The high liquid quickly absorbs the absorbent layer while reducing the diffusion range of the liquid. [Prior Art] The structure of an absorbent article that absorbs menstrual blood excreted from a female genitalia is generally a surface layer in which the surface of the absorbing layer is covered with a liquid permeable surface. The absorbing layer is formed of a mixture of a hydrophilic fiber such as pulp and a superabsorbent polymer (SAP), and the surface sheet is made of a non-woven fabric formed of a hydrophilically treated hydrophobic chemical fiber, or It is a non-woven fabric formed of hydrophilic fibers such as enamel. In the absorbent article, there is an absorbent layer having a higher density formed by hydrophilic fibers in the lower direction of the surface sheet. The liquid received on the surface of the surface sheet is sucked by the hydrophilicity and capillary action of the absorbent layer, and is rapidly absorbed and held by the surface layer by the surface sheet. However, since the menstrual blood viscosity is high and continues to be excreted during the physiology of the female, the liquid is liable to be saturated in the surface sheet when the absorbent layer maintains a certain degree of liquid. That is, the menstrual blood rapidly passes through the surface sheet due to its own weight, but compared with the penetration speed, since the absorption speed of the liquid by the capillary action of the absorption layer is slightly slow, if a large amount of liquid is tolerated in a short time, The liquid absorbing layer is not completely absorbed, and the liquid tends to remain in the surface sheet 1263489 (2). Since the liquid spreads around the surface sheet, the surface sheet is wetted by menstrual blood, which tends to make the skin feel moist, and because the surface of the blood spreads wider, the wearer is visually disgusted. Hey. On the other hand, Japanese Patent Document 1, which will be described later, discloses that an absorbent layer formed of a mixture of a cotton pulp and a superabsorbent polymer and a liquid-permeable surface sheet are interposed with a density specific surface. In the second sheet having a low sheet, the second sheet is formed by joining a hydrophilic composite fiber, and the invention described in the publication is aimed at absorbing the liquid from the surface sheet by the second sheet. The absorption layer ' makes it difficult for the body fluid to stay in the surface sheet and the second sheet. [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. The second sheet spreads around. In the absorbent article described in the above publication, since the area of the second sheet is not particularly limited, when the liquid is diffused along the second sheet, the liquid is easily diffused on the surface sheet. Further, in the above-mentioned publication, since the entire structure is a flat structure, the winter liquid 1263489 (3) the liquid which has permeated through the second sheet by the absorption layer diffuses in the absorption layer having a high density, and leaves the second sheet. The peripheral field 'is also prone to a state in which a large amount of liquid exists in the absorbing layer. In the outer peripheral region 'because the surface sheet is directly placed on the surface of the absorbing layer, it is also easy to saturate the liquid of the surface sheet shortly after the start of use in the above-mentioned outer peripheral field. Therefore, the surface sheet becomes a state of being wetted in a wide range, and it is easy to make the body feel stuffy. The liquid flowing along the surface of the surface sheet is liable to cause side leakage. Further, in the manufacturing process of the absorbent article, generally, the cloth roll wound by the belt-shaped nonwoven fabric for forming the second sheet is used, and the nonwoven fabric pulled out from the cloth roll is cut so as to have a predetermined area. The second sheet described above is used. However, in the case where the cloth roll having the non-woven fabric is wound, the bulkiness (thickness) is flattened due to the pressure of the winding, and since it is stored in this state, the non-woven fabric pulled out from the cloth roll is squashed. status. When the second sheet is formed of the nonwoven fabric, the bulkiness of the second sheet is small, and the internal void is crushed to a high density. Therefore, the speed at which the liquid permeating the surface sheet is sucked into the second sheet becomes slow, and the liquid tends to stay in the surface sheet. Further, the liquid sucked into the second sheet is caused to flow in the second sheet having a higher density and diffused around the second sheet before being absorbed in the absorbent layer, so that a large range of liquid is retained on the second sheet. As a result, the liquid becomes easy to rewet back to the surface sheet. Further, in the second sheet in which the bulkiness is squashed, there is also a problem that the feeling of softness is not obtained. -7- 1263489 (4) The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to provide a liquid which can be quickly absorbed in a limited field and which can quickly absorb liquid overflowing in the peripheral field at any time, and can suppress The diffusion range of the liquid of the surface sheet, and also the absorbent article which is easy to prevent side leakage. [Means for Solving the Problems] The present invention relates to an absorbent article in which an absorbent layer is provided between a back sheet and a liquid-permeable surface sheet, and is characterized in that it is oriented from a center line extending in the longitudinal direction A pressing portion in which the surface sheet and the absorbing layer are pressed into a concave shape is continuously formed in a longitudinal direction at a position spaced apart from each other in the longitudinal direction, and the inner side sandwiched by the pressing portion is a central absorption field, and the above The outer peripheral side of the pressing portion is divided into an auxiliary absorption region, and in the central absorption region, between the absorbent layer having a hydrophilic material and the surface sheet, a structure in which fibers are joined together to form a void is provided and a ratio is provided. In the liquid guiding layer having a low density of the absorbing layer, the liquid guiding layer is formed in the auxiliary absorbing region so as not to overlap the pressing portion, and the absorbing layer is covered by the surface sheet.

15- 1263489 (12) 因接著劑而減少滲透面積之情形。 又，於上述上層吸收體4與液體引導層5之交界面， 藉由塗佈成網狀、櫛梳狀或是螺旋狀之熱熔型接著劑，上 述上j曾吸收體4與液體引導層5接著一起。又，重疊了上 層吸收體4及下層吸收體3者之上面與下面是被親水性之 纖維紙所覆蓋，因此於上層吸收體4與下層吸收層之界面 ，並無夾介接著劑。又，下層吸收體3與背面薄片2之交 界面亦藉由熱熔型接著劑接著。 比上述壓著部9之外側之輪郭線9B外周側之，存在 有上述下層吸收體3以及上層吸收體4之領域成爲輔助吸 收領域1 2。於該輔助吸收領域1 2，在與上述輪郭線9 B緊 鄰之外周側，形成有重疊有下層吸收體3及上層吸收體4 以及表面薄片6之高膨鬆部1 2 a，於比其外周之側，設置 有其下層吸收體3被表面薄片6覆蓋之厚度較薄之領域 1 2 b。而，於超過上述輔助吸收領域1 2之外周側，沒有夾 介上述下層吸收體3以及上層吸收體4，背面薄片2及表 面薄片6是藉由熱熔型接著劑而接著。 如第1圖及第2圖所示，上述輔助吸收領域1 2之高 膨鬆部1 2 a是以將上述壓著部9之外周全周圍住之方式而 形成，又，上述厚度較薄之領域1 2 b，是以將上述高膨鬆 部1 2a之外周全周圍住之方式形成。 其次’說明各構成材料之理想例。 表面薄片6，以使用由化學纖維所形成之氣流不織布 爲理想。作爲化學纖維是使用芯部爲含]·]質量％左右之 -16- 1263489 (13) 氧化鈦之聚對苯二甲酸乙二醇酯（PET )，而鞘部爲聚乙 烯（P E )之芯鞘型複合合成纖維，並藉由熱風將上述芯鞘 型複合合成纖維彼此間予以熱熔著使之接著者。於上述芯 部添加了氧化駄之心銷型複合合成纖維，表面變得更光滑 ，表面薄片6之質感會變得更好。又作爲表面薄片6，若 使用氣流不織布時，由於其爲膨鬆度高且於纖維間形成有 空隙者，故液體之透過性良好。 形成上述表面薄片6之芯鞘型複合合成纖維，以藉由 在其內部揉入有界面活性劑等之親水性油劑，或是於其表 面塗層以上述親水性油劑，經親水性處理之化學纖維，與 於其表面塗佈有撥水性油劑之撥水性纖維之混合而形成爲 理想。藉由混合該撥水性纖維，具有防止液體於表面薄片 6擴散之效果。又於混合撥水性纖維時，如第4圖（A ) 所示，於表面薄片6形成多數之透液孔1 5，以採用液體 易於透過表面薄片6之構造爲理想。上述撥水性纖維，以 含有對於表面薄片6之質量之質量比爲5〜30%理想。若 超過3 0 %，則會變得液體易於在表面薄片6之表面彈開， 降低表面薄片6之液體透過能力。又若未滿5 %，則防止 液體擴散之效果會低減。 又，表面薄片6，亦可爲由化學纖維所形成之點黏（ pointbond)不織布或紡黏（spunbond)不織布、或嫘縈等 之親水性纖維及含有上述撥水性纖維之水針（s P u η 1 a c e ) 不織布。或，亦可爲形成有多數透液孔之樹脂薄膜、或是 於樹脂薄膜與不織布之層壓材形成有多數之透液孔者。 -17- (14) 1263489 全都爲以表面薄片6之基重在15〜60g/m2之範圍爲 理想。若未滿上述範圍則不能得到足夠之表面強度’於濕 潤狀態有產生破損之虞。又若超過上述範圍，則表面薄片 6會變僵硬，會有穿著中產生不適感之虞。又表面薄片6 之密度以在0 . 1 2 g / cm3以下爲理想。由於女性生理時之 經血黏度較高，故爲了使該經血滲透，密度以在上述値以 下爲理想。 又，上述透液孔1 5，如第4圖（A )及第6圖所示， 於其表面之開孔尺寸Hd爲0.5〜2.0mm，縱長方向之排列 間距Hy爲2〜5mm，橫向方向之排列間距Hx爲1〜4mm ，而Hy比Hx長，透液孔1 5之排列，如第6圖所示，各 透液孔1 5於X方向及Y方向爲位置相互錯開之關係。 上述液體引導層5，爲具備有親水性之化學纖維，例 如揉入界面活性劑或於表面塗佈有界面活性劑之化學纖維 彼此間接合並形成三次元之骨架而具備有空隙之構造者。 如此藉由使用具備有空隙之液體引導層5，會變得液體易 於滲透過表面薄片6並藉本身重量進入上述空隙內，又， 在被吸收至位於其下之吸收層之前，可將液體保持於空隙 內。 作爲上述構造者’可舉由親水性化學纖維所形成之具 備有透液機能之氣流不織布或，同時具備有透液機能與保 液機能之氣流成形不織布。 上述氣流不織布，是使用芯部爲聚丙烯（p p )而鞘部 爲聚乙烯（P E )之偏芯形態之芯鞘型複合合成纖維（例如 -18- (15) 1263489 纖度爲4.4 dtex，纖維長爲50mm )之纖維層，藉由使用熱 風將上述芯鞘型複合合成纖維之鞘部彼此間熱熔著而接著 者。 或上述氣流不織布，是使用芯部爲含有1 · 1質量％左 右之氧化鈦之聚對苯二甲酸乙二醇酯（ρ Ε τ )，而鞘部爲 聚乙烯（PE )之芯鞘型複合合成纖（例如纖度爲2.2dtex 纖維長爲44mm )之纖維層，藉由使用熱風將上述芯鞘型 複合合成纖維之鞘部彼此間熱熔著而接著者。 可作爲上述液體引導層5使用之氣流不織布之密度在 0.005g / cm3以上0.1g/cm3之範圍，不過如下述般再將 從布捲拉出之上述氣流不織布予以熱處理，使其恢復鬆度 後作爲液體引導層5使用較理想。 例如於上述之氣流不織布，藉由115 °C〜3 00 °C，更 佳爲1 3 0 °C〜2 0 0 °C (例如1分鐘之1 3 5 °C熱風處理）之熱 處理，可使上述氣流不織布之厚度，恢復至1 .2〜4倍之 範圍。 較佳爲使用將上述氣流不織布予以熱處理恢復膨鬆度 後，再將上述氣流不織布冷卻者。藉此將藉由熱處理恢復 之膨鬆度，藉由急冷維持該膨鬆度，可製得低密度之具緩 衝性之氣流不織布。 恢復膨鬆度後之上述氣流不織布之密度，比上述上層 吸收體4及表面薄片6還低，以使用乾燥狀態下之密度再 〇.〇〇5g/ cm3以上0.02g / cm3之範圍者爲理想。密度若未 滿上述範圍，則纖維間之空隙會變太小，會變得液體難以 -19- 1263489 (16) 滲透過表面薄片6並利用本身重量進入上述空隙，將經血 從表面薄片6朝向上層吸收體4A之引導機能會惡化。又 若超過上述範圍，則空隙會變太大，延伸於纖維之三次元 方向之骨架之強度會降低，會變得易於被身體之壓力壓扁 膨鬆度。 又恢復膨鬆度後之上述氣流不織布，於濕潤狀態下賦 予 980Pa(10g/cm2)之壓力時之密度，以在 0.005g/ cm3〜0.0.4g/cm3之範圍內爲理想。 又，恢復膨鬆度後之上述氣流不織布之每片之厚度， 是在乾燥狀態及濕潤狀態下在1.5mm〜3mm，較佳爲2mm 〜3mm。又，於濕潤狀態下賦予9 8 0Pa ( 10g/ cm2 )之壓 力時之厚度爲 0 · 5 m m〜2 m m，較佳爲0.5 m m〜1 . 5 m m。又 除去上述壓力後之厚度之恢復比例，若於加壓時作爲1， 則爲1 · 5倍以上爲理想，更佳爲1 · 8倍以上。以將上述氣 流不織布重疊爲複數片形成液體引導層5爲理想。 又，於上述乾燥狀態及濕潤狀態之厚度與密度，以及 於濕潤狀態且施加上述壓力時之厚度與密度之測量，是基 於以下之（實施例B )之（1 1 )所記載之測量方法。 若使用上述液體引導層5時，在處於不斷承接經血之 狀態，且施以體壓作用時，亦可於液體引導層5內保持空 隙，可於液體引導層5內引導且保持液體，可防止液體朝 向表面薄片6回滲。又，體壓減輕時，可立刻恢復膨鬆度 ，可長時間維持使重覆而來之液體之透液機能。 又，液體引導層5整體之基重，在15〜300g/m2之 - 20- (17) 1263489 範圍，更佳爲2 0〜1 0 0 g / m 2。只要在上述範圍，即可使 在液體引導層5內之液體朝向吸收層移動，又，液體被吸 收於吸收層前，可將液體保持於液體引導層5內之空隙。 作爲液體引導層5使用之上述氣流成形不織布，是將 上述親水性之天然纖維或作爲再生纖維素纖維及化學纖維 ’與熱可塑性樹脂纖維混合者使其浮於空氣中，將上述纖 維回收於網上並積層後，施以加熱處理，使上述熱可塑性 樹脂纖維之表面熔融，藉由熱可塑性樹脂纖維與親水性纖 維熱熔著而製造出來。例如，作爲親水性纖維，可使用木 材紙漿、嫘縈、醋酸嫘縈、紙漿以外之天然纖維素纖維、 纖維素鹼化紙漿、交聯紙漿等，作爲化學纖維可使用芯部 爲聚丙烯（PP )而鞘部爲聚乙烯（PE )之芯鞘纖維（例 如纖度爲1.7dtex，纖維長爲13mm)。 又’上述纖維亦可爲藉由乳膠形態之樹脂黏劑接著者 〇 該氣流成形不織布，爲化學纖維間，或是上述親水性 纖維及化學纖維彼此接合，具備有形成空隙之三次元骨架 構造者。將該氣流成形不織布作爲液體引導層5用時，與 氣流不織布同樣爲具備有液體藉由本身重量進入空隙內之 透液機能，同時由於含有天然纖維或再生纖維素纖維等之 親水纖維，故親藉由水作用，可將欲滯留於表面薄片6之 液體吸入液引導層5。 又’該氣流成形不織布，從布捲拉出之後，以1 〇 〇〜 3〇〇°C，較佳爲130〜2 0 0 t之熱予以熱處理！分鐘左右， -21 - 1263489 (18) 恢復膨鬆度爲理想。使用氣流成形不織布時之，於乾燥時 之密度、於濕潤時且加壓時之密度、1片不織布之厚度、 於濕潤時且加壓時之厚度、加除去壓時之厚度之恢復率、 基重等之理想軸Η ’爲與上述氣流不織布相同。 又於上述液體引導層5，使用將織網藉由針軋（ needle punch)法或Highloft法等之製法處理之不織布， 將此予以熱處理恢復膨鬆度者，或，雖非不織布，亦可使 用具有三次元骨架，並藉由熱恢復膨鬆度之材料，例如氨 基甲酸乙酯等。 又’液體引導層5，亦可由將其整體予以熱處理恢復 膨鬆度之上述氣流不織布或氣流成型不織布而形成，不過 ，液體引導層5，亦可部分熱處理，爲存在有恢復膨鬆度 之部分與沒有恢復膨鬆度之部分者。例如，於使用縱長方 向之尺寸較長之液體引導層5時，亦可僅把與膣口對向之 則方部分施以熱處理作成低密度，而與後方之肛門或臀溝 對向之部分則不恢復膨鬆度作成比前方部分密度高之狀態 。藉此’於與膣口對向之部分，可於短時間將大量承接之 經血快速移動至吸收層，後於方部分，藉由事先將其作成 局密度’可將表面薄片所承受之較少量之液體快速地吸入 。或相反地亦可前方部分不熱處理，僅將後方部分熱處理 ，將後方部分作成低密度。 構成上述液體引導層5之纖維之纖度，只要在1 . 8〜 3 3 dt ex即可，爲了使來自身體之押壓力等被開放時之膨鬆 度之恢復性佳，且作成不易發生液體回滲現象（回流現象 -22- 1263489 (19) )，上述纖度以在2.4〜1 1 dtex爲理想。 又，液體引導層5，是將上述不織布折疊成3片重疊 而使用。在此，若用1片不織布製造出與將其重疊成3片 之不織布之基重相同者時，纖維密度會變高，且厚度會變 小，內部之空隙也會變小。因此，上述般之液體藉其本身 重量導於上述空隙內之機能會降低。又，如第3圖所示， 使折疊成3片重疊之不織布之2條折線朝向縱長方向，若 使兩折線分別位於液體引導層5之側緣5 a及側緣5 b，則 折疊成3片重疊之各層會變得在層間之界面易於朝第3圖 之左右方向移動。亦即，液體引導層5於左右方向可持有 自由度，在中央吸收領域1 1緊密接著於膣口之狀態下， 液體引導層5可對應身體之移動作比較自由之移動。因此 可隨時維持設置有液體引導層5之領域與上述膣口之緊密 接著性，且膣口較不會感到不適少。 在液體引導層5之藉由不織布之折疊而形成之層數未 必限於3片重疊者，亦可爲2片重疊，或是4片重疊以上 。若重疊片數多時液體可進入不織布之層間之空隙，可將 許多表面薄片6所承接之液體導於液體引導層5。但是， 若折疊次數太多，則形成液體引導層5之製程會變多，生 產性會降低。且若重疊片數多，則上述層間之空隙會變太 多，會有液體滯留於該部分之虞。 因此’作爲不織布之折疊次數，從液體之引導機能及 生產效率之點來考量，以2片重疊乃至5片重疊左右爲理 想。但是’如上述般爲了使其具有朝不織布之各層之左右 -23- 1263489 (20) 方向之自由度，且作成適當之層間之界面之數，以3片重 疊爲理想形態。 又，作爲上述液體引導層5，亦可將裁斷成 WlxLl 之大小之不織布，作成例如3片重疊者。如此重疊者，可 使其在密度或各層之自由度與上述之折疊者發揮同樣機能 。但是，爲了使液體引導層5不會嚙入於壓著部9內，必 須將不織布，以上述寬幅尺寸W爲非常小之尺寸之方式 裁斷，不過要將不織布裁斷成如此之小尺寸是很困難的， 因此以將不織布折疊形成WlxLl之大小之液體引導層5 爲理想。 上層吸收體4，是由粉碎紙漿、纖維素鹼化紙漿、交 聯紙漿等之紙漿之積層體且基重爲例如23 0g/ m2者所形 成。下層吸收體3，是使用相對於上述紙漿含有1 . 5〜2.0 質量％之高吸收性聚合物者，且基重及厚度爲上述上層吸 收體4之80%以下者，例如基重爲160g / m2者。又，上 述上層吸收體4及下層吸收體3在重疊狀態下，於其上下 面被纖維紙夾住之狀態下使用。又，於下層吸收體3，形 成有第1圖所示之格子狀圖案15之壓花。 而，上述上層吸收體4及下層吸收體3之密度，以在 0. 1〜0.6g/ cm3之範圍爲理想。若未滿上述範圍則剛性會 變太低不能維持生理用衛生棉1之形態，穿著於身體時會 有發生縐褶或扭曲之虞。又若超過上述範圍，則會變得僵 硬易於使身體感到不適。不過，藉由如上述般在下層吸收 體3形成有格子圖案之壓花，在上述密度之範圍內下層吸 -24- 1263489 (21) 收體3密度會比上層吸收體4高。 又，爲了使被液體引導層5引導之液體，易於被上層 吸收體4吸引，相對於液體引導層5之密度，上層吸收體 4之密度以在其2倍以上爲理想，更佳爲5倍以上。 又背面薄片2，爲不透液性且通氣性之薄片，是形成 有細微通氣孔之聚乙烯（PE )薄膜、或聚丙烯（PP )薄 膜等。例如，爲藉由在上述之塑膠薄片混入 CaC03， BaS04等之無機塡充料並予以延伸處理，於薄膜上形成有 適當分散之細微通氣孔，提昇了通氣性者，且厚度爲1 5 〜5G//m左右者。或，亦可爲於不織布層壓以熱可塑性樹 脂之材料。 如第3圖所示，於上述背面薄片2之外面，塗佈有以 所定之橫向寬幅尺寸，連續延伸於縱長方向之帶狀之感壓 接著劑層7。而，於使用前之狀態，上述感壓接著劑層7 是以離型薄片（圖示省略）覆蓋保護。 上述壓著部9，爲藉由使用加熱輥筒之壓花加工形成 者’在下層吸收體3、上層吸收體4以及表面薄片6重疊 之狀態，於下層吸收體3之外面，表面用平滑之輥筒擋接 ，於表面薄片6之表面側用具備有壓花圖案之凸部之加熱 輥筒擋接，下層吸收體3、上層吸收體4以及表面薄片6 被上述凸部加壓且加熱。其結果，於上述壓著部9，在如 第2圖所示之寬幅尺寸爲（5之部分，包含於各層及薄片之 熱可塑性纖維會熔融而形成薄膜狀之熔融部9D。於上述 熔融部9D之間，形成有其雖沒有變成薄膜狀，但其吸收 -25- 1263489 (22) 層比壓著部9以外之領域密度高之高密度部9 E。 而，於上述3層形成有壓著部9後’於上述下層吸收 體3之下側設置有背面薄片2。 於該實施形態，上述熔融部9D，是以相對於壓著部 9之延伸方向爲傾斜線狀之方式形成。上述熔融部9D之 寬幅尺寸（5例如爲0.2〜1 . 5 m m，上述熔融部9 D之間距P 例如爲1〜5 m m。又壓著部9之寬幅尺寸W a爲2〜4 m m 左右。 如上述般，爲了適當形成熔融部9D及高密度部9E， 要將上述加熱輥筒之溫度設定於1 2 0 °C以上，輥筒間之壓 力以在9 8 0〜24 5 0Pa之範圍內選擇爲理想。若以上述之溫 度及壓力形成壓著部，則接著於內褲裝著於身體後從兩側 面受到大腿部之壓力時，如第5圖所示，在壓著部9之右 側壓著部9a及左側壓著部9b之一部分，生理用衛生棉1 會變得易於折彎。又，不會有形成壓花之壓力太高而在熔 融部9D產生一部分破損等之問題。 又如上述般，於中央吸收領域1 1，液體引導層5之 各緣部位於比壓著部9更內側處，液體引導層5不會重疊 到壓著部9。若上述液體引導層5重疊到壓著部9時，由 於形成液體引導層5之不織布爲膨鬆度高且由纖維形成之 三次元骨架者，故於壓著部9之各薄片之壓著強度會降低 。此時，於壓著部9之表面薄片6及上層吸收體4會變成 沒有固定或是固定變弱，於中央吸收領域1 1所承接之經 血沿著表面薄片6擴散或是在上層吸收體4內擴散之時， -26 - 1263489 (23) 於上述壓著部9會變得不能防止液體之擴散。 又，於壓著部9之壓著強度較弱時，會較難使中央吸 收領域1 1朝向身體側凸狀變形，且於中央吸收領域u及 其周邊，各薄片會移位錯開，易於在表面薄片6或液體引 導層5產生扭曲。其結果，會變得中央吸收領域1 1難以 緊密接著於膣□，不能達成欲於中央吸收領域1 1內重點 吸收液體之初期目的。 從以上可得知，藉由液體引導層5不會重疊於壓著部 9之構成，可使中央吸收領域1 1朝向身體突出變形，可 使中央吸收領域1 1柔軟地緊密接著於膣口。又藉由壓著 部9可發揮防止液體擴散之機能。 以下，說明各部之理想尺寸。第1實施形態之生理用 衛生棉1是於晝間等使用之一般尺寸，於橫向方向中心線 Ο X - Ο X之寬幅尺寸爲8 0 m m，於縱長方向中心線0 y - 0 y之 長度尺寸爲210mm左右。 又，被上述壓著部9圍住之中央吸收領域1 1必須具 備有可緊密接著於女性膣口之面積，寬幅尺寸 W2在 25mm〜50mm之範圍，縱長方向之尺寸L1在50〜110mm 之範圍。又，於第8圖所示之適於夜間穿著之加長形態， 其上述中央吸收領域1 1以延伸至肛門之後方領域爲理想 ’此時之中央吸收領域1 1之縱長方向尺寸之上限爲 2 8 0 m m左右。 上述液體引導層5之寬幅尺寸W1及縱長尺寸L1’ 是對應上述中央吸收領域1 1之面積而設定者，不過於液 -27- 1263489 (24) 體引導層5之緣部與壓著部9之內側之輪郭線9A之間’ 必須隔開某程度之間隔。例如，上述液體引導層5之緣部 ，與上述輪郭線9 A之間隔，亦即（W 2 - W 1 )/ 2，以及 (L 2 - L 1 ) / 2，以在1〜]〇mm之範圍爲理想，更佳爲2 〜6mm。只要在上述範圍，於形成壓著部9之時，不會有 上述液體引導層5之緣部重疊到壓著部9之虞。 於上述實施形態之上層吸收體4之橫向方向中心線 〇x-Ox之寬幅尺寸爲55 mm左右，於縱長方向中心線〇y-〇y之長度尺寸爲120mm左右。又下層吸收體3，其上述 寬幅尺寸爲75mm左右，其長度尺寸爲180mm左右。又 ，第3圖所示之輔助吸收領域中之高膨鬆部1 2 a之寬幅尺 寸WB，以在3〜10mm左右爲理想。 於使用該生理用衛生棉1之時，首先要將保護感壓接 著劑層7之離型薄片剝離，夾介感壓接著劑層7，接著於 內褲***部2 0之內側使用。 在將內褲及生理用衛生棉1穿著於身體之狀態，上述 ***部2 0以及生理用衛生棉1，會受到來自兩側大腿部 之緊束力。於上述生理用衛生棉1，由於在從縱長方向中 心線0 y - 0 y朝向橫向方向等間距之位置形成有延伸於縱 長方向之右側壓著部9a以及左側壓著部9b，故藉由上述 緊束力，生理用衛生棉1之上述右側壓著部9 a以及左側 壓著部9 b之部分會發揮其作爲絞鏈之機能，生理用衛生 棉1 ’以該絞鍵之部分作爲折線並如第5圖所示般被折彎 -28- (25) 1263489 特別是，設置於中央吸收領域1 1之液體引導層5沒 有重疊到壓著部9，於壓著部9，其下層吸收體3及上層 吸收體4僅存在於其上而已。因此，可將上述壓著部9， 與壓著部9以外之領域之間之剛性差及厚度差作得較大， 會變得生理用衛生棉1，易於在右側壓著部9 a及左側壓 著部9b之位置上折彎。 此時，來自大腿部之緊束力，會從上述右側壓著部 9a及左側壓著部9b作用於中央吸收領域11，藉由該緊束 力，中央吸收領域1 1之表面會朝向身體凸狀彎曲，位於 中央吸收領域1 1之表面薄片6之表面會易於緊密接著於 女性之膣口。此時，中央吸收領域1 1，成爲具備有下層 吸收體3、上層吸收體4以及液體引導層5之膨鬆度高者 ，而且由於液體引導層5爲密度較低之材料，故對膣口之 觸感較柔軟。 從膣口***出來之經血等之黏度高較之液體，主要被 在表面薄片6之中央吸收領域1 1承接，該液體，滲透過 表面薄片6被液體引導層5承接。亦即，由於液體引導層 5具備有其化學纖維被接合且具有延伸於三次元方向之骨 架而形成有空隙之構造，故液體會藉其本身重量滲透過表 面薄片6，被引導至上述液體引導層5之空隙內。再者被 吸收於液體引導層5內之液體，藉由位於其下之密度較高 之上層吸收體4之親水作用以及毛細管作用被吸引，被上 層吸收體4吸收保持。再者，被上層吸收體4吸收之液體 ，被其下之下層吸收體3吸收保持。 -29- (26) 1263489 上述液體引導層5，其使液體朝下移動之能力很高， 且在液體被吸入上層吸收體4之前，由於液體被保持於液 體引導層5內’故表面薄片6不易呈液體飽和狀態。因此 ’表面薄片6不易使身體肌膚感到濕潤。 又’因座姿等藉由身體體重之押壓力產生作用時，該 押壓力會被表面薄片6及液體引導層5承接。上述液體引 導層5 ’由於是藉熱處理恢復膨鬆度之低密度層，故可發 揮作爲緩衝層之機能。又由於即使加上來自身體之押壓力 而上述液體引導層5被壓縮時，亦可維持高空隙率，故可 暫時保持來自上述表面薄片6之液體並長時間保持使液體 被吸入上層吸收體4之機能。又來自身體之押壓力開放時 ’由於上述液體引導層5之復原膨鬆度之機能高，故於上 述液體引導層5，會隨時持續形成有空隙。 於上述表面薄片6含有撥水性纖維，藉此可防止液體 之擴散，不過由於如上述般表面薄片6可維持膨鬆度，易 於維持在內部形成有空隙之狀態，故即使包含有上述撥水 性纖維，亦可充分發揮表面薄片6之透液機能。 於該實施形態，如第4圖（A )所示，由於從表面薄 片6到液體引導層5形成有多數之透液孔1 5，故表面薄 片6之表面所承接之液體，會滲透過上述透液孔1 5移動 到液體引導層5。因此，表面薄片6所承接之液體，易於 在液體引導層5藉本身重量下降，藉此，更易於防止液體 殘留於表面薄片6或液體之擴散。 如此，於該生理用fei生棉1 ’集中重覆***於中央吸 -30- 1263489 (27) 收領域1 1之中央部分之液體’會滲透過表面薄片6被液 體引導層5承接，成爲液體不易在表面薄片6擴散者。又 ，由於液體引導層5密度較低’故會抑制在液體引導層5 內之液體朝向周圍擴散，藉此’亦可抑制液體於表面薄片 6擴散。 滲透過表面薄片6及液體引導層5之液體在上層吸收 體4被吸收、擴散，再被下層吸收體3吸收、擴散。不過 ，於中央吸收領域1 1，由於上層吸收體4及表面薄片6 間之距離較開，故於上層吸收體4內擴散之經血之顏色不 易從表面側以目測確認。如此於表面薄片6之液體之擴散 領域有限，且由於在上層吸收體4之液體之擴散，從表面 側看不見，故易於防止穿著者於使用中之目視生理用衛生 棉1之表面時，心理上感到不安。 又，液體在位於中央吸收領域1 1內之上層吸收體4 及下層吸收體3內朝周圍擴散時，上述壓著部9會發揮阻 止液體擴散之機能。亦即，沿著上層吸收體4與下層吸收 體3朝向橫向方向擴散至右側壓著部9 &及左側壓著部9 b 之液體，會集中於高密度部9E，再流動於高密度部9E間 ’並沿著右側壓著部9a及左側壓著部9b朝向縱長方向傳 導。因此，中央吸收領域1 1所承接之液體，難以超過壓 者部9傳導至該周圍之輔助吸收領域1 2。 於上述中央吸收領域1 1之外周，設置有輔助吸收領 域1 2 ’不過如第4圖（B )所示，於與壓著部9緊臨之外 側存在有較厚之高膨鬆部】2a，如第5圖所示在變形之狀 -31 - (28) 1263489 態下，上述高膨鬆部1 2 a易於合貼於大***外側之***部 分。又如第5圖所示，由於壓著部9同時埋沒於膨鬆度高 之中央吸收領域1 1與上述高膨鬆部1 2 a之間，故密度高 且剛性高之壓著部9不會直接與身體接觸，壓著部9不會 給予身體剛直感。 而’沿著股胯部流動之經血附著於輔助吸收領域]2 之時’又’沿著中央吸收領域1 1之表面流動之經血超過 壓著部9附著於輔助吸收領域1 2之表面之時，該液體， 藉由位於表面薄片6正下方之上層吸收體4之毛細管作用 之液體之吸收力，會快速地滲透過表面薄片6被上述上層 吸收體4吸收。如上述般於中央吸收領域1 1之被上層吸 收體4或下層吸收體3吸收之液體由於難以超過壓著部9 傳到其外側，故於上述輔助吸收領域1 2之上述上層吸收 體4與下層吸收體3不易因大量之液體而產生飽和。又， 於輔助吸收領域1 2位有下層吸收體3及上層吸收體4， 吸收層之材料之容積會變大。因此，於輔助吸收領域12 之附著於表面薄片6之表面之液體，會立刻被其下之吸收 層吸收，易於防止液體之側漏。 又，於輔助吸收領域1 2，於表面薄片6之正下方位 有密度高之上層吸收體4，由於藉其親水力及毛細管作用 ’附著於表面薄片6之表面之液體會被快速吸引，故於該 輔助吸收領域1 2，沒有必要於表面薄片設置透液孔。不 過，亦可於該輔助吸收領域1 2之表面薄片6形成有透液 孔。 -32- 1263489 (29) 又下層吸收體3是以大範圍設置於中央吸收領域1 1 及輔助吸收領域1 2，由於該下層吸收體3爲基重及厚度 較小者，且於內部具備有高吸收聚合物，故下層吸收體3 之液體保持容量會變大。因此，於中央吸收領域Π及輔 助吸收領域I 2，在下層吸收體3會變得可保持較多之液 體’作爲生理用衛生棉1整體，成爲液體之吸收容量大者 〇 如上述般，於上述生理用衛生棉1，藉由壓著部9區 畫有中央吸收領域1 1，將該中央吸收領域1 1作成易於緊 密接著於膣口，於該中央吸收領域1 1主要爲承接液體。 而’於該中央吸收領域1 1，對於液體之重覆供給，表面 薄片6也不易飽和，於表面薄片6之液體不易擴散。而， 萬一液體超過中央吸收領域1 1附著於輔助吸收領域1 2之 時’在輔助吸收領域1 2會立刻捕捉該液體地發揮機能。 桌7圖乃至第11圖是顯不本發明之另一實施形態。 於此等實施形態，關於與上述第1實施形態相同之構成， 則附以與第1實施形態相同之符號並省略該詳細說明。 第7圖是顯示作爲本發明之第2實施形態之吸收性物 品之生理用衛生棉1 A之平面圖。 該生理用衛生棉1 A，僅壓著部9之圖案形狀相異， 其他之構成以及尺寸等爲全部與第1圖乃至第5圖所示之 生理用俾ί生棉1相同。 於第7圖所示之生理用衛生棉1 a，作爲壓著部僅形 成有右側壓著部9a以及左側壓著部9b，沒有形成第1圖 -33- (30) 1263489 所示之生理用衛生棉1之前方壓著部9c以及後方壓著部 9d。該右側壓著部9a及左側壓著部9b之構造等是與第1 圖及第2圖等所示之上述生理用衛生棉相同。 於該生理用衛生棉1 A，由於在左右兩側也設置有延 伸於縱長方向之右側壓著部9a以及左側壓著部9b，故穿 著於股胯部時之變形狀態是與第5圖相同。又，該生理用 Μ生棉1 A ’其由右側壓著部9 a與左側壓著部9 b夾住之 領域爲中央吸收領域1 1 A，於比右側壓著部9 a更右外側 處，以及比左側壓著部9b更左外側處，形成有輔助吸收 領域1 2 A。而在中央吸收領域1 1 A以及輔助吸收領域1 2 A 之液體之引導機能或吸收機能，是與上述生理用衛生棉1 之中央吸收領域Π以及輔助吸收領域1 2相同。 又’ g亥生理用Μ生棉1 A，亦爲夾介縱長方向中心線 〇 y - 0 y左右對稱之形狀，且夾介橫向方向中心線Ο X - Ο X 於前後呈對稱之形狀。而，從橫向方向中心線Ox-Ox至 右側壓著部9a與左側壓著部9b之前端之長度尺寸LB， 是比從上述橫向方向中心線至液體引導層5之前緣5c之 長度尺寸LA還長。此於從橫向方向中心線至右側壓著部 9 a與左側壓者部9 b之後端之長度尺寸，以及至液體引導 層5之後緣5 d之長度尺寸也爲相同情形。 而，上述Lb— La以在3mm以上爲理想，更佳爲5mm 以上。 藉由如此構成，中央吸收領域1 1 A之中央部所承接 之液體，從表面薄片6夾介液體引導層5被上層吸收體4 -34- 1263489 (31) 及下層吸收體 3吸收之經血’在朝向上述各吸收體3、4 兩側面擴散之時，可藉由上述右側壓著部9 a及左側壓著 部9 b阻止該擴散，位於輔助吸收領域1 2 A之各吸收體3 、4不易呈液體飽和現象。 第8圖是顯示作爲本發明之第3實施形態之吸收性物 品之生理用衛生棉1 B之平面圖。 該生理用衛生棉1 B，其基本構造是與上述生理用衛 生棉1及1 A以及1 D相同，不過僅於整體之大小及壓著 部之平面圖案之形狀爲相異。 該生理用衛生棉1 B之縱長方向之尺寸較長，且於後 方之整體之寬幅方向會變寬，於穿著於股胯部時上述後方 部分會成爲可緊密接著於臀部之所謂護臀部。 於該生理用衛生棉1 B，背面薄片、下層吸收體3 A、 上層吸收體4A、液體引導層5A之縱長方向之尺寸較長。 而，壓著部9 0也於縱長方向爲較長之形態。該縱長型之 壓著部9 0，具備有以圍住中央吸收領域1 1 B之方式連續 形成之右側壓著部 90a、右側壓著部 90b、前方壓著部 9〇c以及後方壓著部90d。又於比前方壓著部90c更前方 處，設置有一對前方延長壓著部90e、90f。該前方延長壓 著部90e、90f，以隨著朝向前方彼此之間隔越寬之方式傾 斜延伸，前方延長壓著部90e、9 Of之前端部，分別位於 W生理用衛生棉緣邰離開之位置。 再者，於比右側壓著部90a更內側處設置有較短之內 側壓著部90g，於比右側壓著部90b更內側處亦同樣設置 -35- 1263489 (32) 有較短之內側壓著部9 0 h。 又，如第8圖所示，上述壓著部90之各部分具備有 所定之寬幅尺寸，不過於該寬幅內’與第2圖所示之實施 形態相同，其薄膜狀之熔融部9D及高密度部9E是沿著 壓著部之線方向交互地形成。 又，上述液體引導層5A，於上述中央吸收領域1 1B 具備有於縱長方向較長之面積，並以不會重K到上述壓者 部9 0之方式設置。而於壓著部9 0之外周形成有輔助吸收 領域12B 。 於該生理用衛生棉1 B，由於中央吸收領域1 1 B於縱 長方向較長，故該中央吸收領域1 1 B可從膣口合貼到臀部 。上述壓著部90之圖案形狀，由於在前方延長壓著部 9 Oe、9 Of之一部分，生理用衛生棉易於折彎，故生理用衛 生棉易於合貼於膣口前方之恥丘附近。 又由於中央吸收領域1 1 B之前方領域及後方領域，以 內側壓著部9 0 h、9 0 g爲起點易於折彎，故中央吸收領域 1 1 B之前方領域易於合貼於膣口，後方領域易於合貼於臀 部之溝內。 而’由於藉由位於中央吸收領域 Π B之液體引導層 5 A，可將表面薄片6 A所承接之經血引導至其下之上層吸 收體4 A與下層吸收體3 A，故中央吸收領域1 1 B所承接 之經血，不易沿著表面薄片6從上述中央吸收領域丨〗B超 越壓著部9 0朝向周圍擴散。因此，即使是生理用衛生棉 1 B之後方部分，亦即護臀部分之縱長方向之長度或橫向 -36- 1263489 (33) 方向之寬幅尺寸較小或較薄者，也易於防止經血朝向 方向漏出。 又液體引導層5 A爲縱長型，不過以不會重疊到 壓著部9 0 a、右側壓著部9 0 b、前方壓著部9 0 c及後 著部90d，以及前方延長壓著部90e、90f，再加上不 疊到內側壓著部90g、90h爲更佳之方式，位於從各 著部離開之處。因此，可將上述各壓著部形成均等之 狀態，生理用衛生棉1 B整體變得易於合貼於身體地 。特別是，若將液體引導層5 A以不會重疊到上述內 著部90g、9 Oh之方式配置時，可將上述內側壓著部 、90h形成均等之壓著狀態，可易於以上述內側壓 9 0 g、9 0 h爲起點將中央吸收領域1 1 B之上述前方領 後方領域折彎。 又，上述液體引導層5A亦可作成不重疊到上述 壓著部90g、9 Oh。例如用液體引導層5 A之厚度較大 挺度較高之材料形成時，藉由將該液體引導層5 A用 內側壓著部90g、90h壓縮，可易於使具備有縱長之 引導層5 A之中央吸收領域1 1 B，以上述內側壓著部 、9 Oh作爲起點並如上述般彎曲。 又，於第8圖之實施形態，前方延長壓著部90e， ，及內側壓著部90g、90h亦可不特別設置。 又於上述各實施形態之生理用衛生棉1、1 A、1 B 爲於兩側緣部不具有側翼之形狀，不過於上述各實施 之生理用衛生棉亦可形成從兩側緣部朝向側面凸出之 臀部 右側 方壓 會重 個壓 壓縮 變形 側壓 90g 著部 域及 內側 、硬 上述 液體 9〇g .90f ，皆 形態 側翼 -37 - (34) 1263489 部。 第9圖，是以作爲其一例之第1圖及第2圖所示之生 理用衛生棉1之構造爲基本，顯示形成上述側翼部之第4 實施形態。 第9圖所示之生理用衛生棉1 C，從該兩側緣部之大 致中央部分設置有朝向兩側面延出之一對側翼部2 i、2 i 。於該生理用衛生棉1 C，其背面薄片2之兩側，緣部成爲 與上述側翼部2 1、21相同之形狀，不過表面薄片6之右 側緣部6 A及左側緣部6B，僅延伸至側翼部2 1、2丨之基 部。而於左右兩側部，由疏水性不織布或經撥水處理之不 織布所形成之不透液性薄片22、22重疊於最表面。該薄 片2 2、2 2之內側之緣部2 2 a、2 2 a ’在從縱長方向中心線 〇 y -

1263489 (36) 延長壓者部9 e與則方延長壓著部9 f之前方之終端，位於 從上述則緣部1 C及右側緣部1 A以及左側緣部1 B離開之 處。 又，於後方領域，形成有從右側壓著部9 a及後方壓 著部9d之交界再往後方延伸之後方延長壓著部9g，也形 成有從左側壓著部9b及後方壓著部9d之交界再往後方延 伸之後方延長壓著部9H。上述後方延長壓著部9g位於右 側壓著部9 a之延長線上，後方延長壓著部9 Η位於左側壓 者部9b之延長線上。而’後方延長壓著部9g及後方延長 壓著部9H，以隨著朝向生理用衛生棉之後緣部：D，離縱 長方向中心線〇y-〇y越開之方式傾斜，於後方延長壓著 部9g及後方延長壓著部9H之後方之終端，位於從上述 後緣部1 D及右側緣部1 A以及左側緣部1 B離開之處。 其次於第1 1圖以平面圖顯示之本發明之第6實施形 態之生理用衛生棉1 E，其生理用衛生棉之本體部分之構 造是與第9圖所示之生理用衛生棉1 C相同之構造，具備 有延長於左右兩側部之側翼部2 1、2 1，且具備有薄片22 、22 ° 而，於夾住兩薄片22、22之緣部22a與22a之領域 ，形成有與第1 〇圖所示之生理用衛生棉1 D相同之圖案 之壓著部190。 於上述生理用衛生棉1 D及1 E，其設置有被右側壓著 部9a、左側壓著部9b、前方壓著部9c以及後方壓著部 9d圍住之中央吸收領域1 1，亦即液體引導層5之領域， -40- (37) 1263489 如第5圖所示是朝裝著者側凸出地變形，上述中央吸收領 域1 1會易於緊密接著於身體之***部。 再於比前方壓著部9c更前方之領域，前方延長壓著 部9e及前方延長壓著部9f，是以隨著朝向前緣部1 C相 互離得越開之方式相互對向形成。因此，被前方延長壓著 部9 e與右側緣部1 A夾住之領域，以及被前方延長壓著部 9f與左側緣部1 B夾住之領域，易於以前方延長壓著部9e 與前方延長壓著部9f作爲彎曲起點朝向身體方向變形。 因此，生理用衛生棉易於合貼於身體之股胯部之前方部分 〇 同樣地於後方領域，被後方延長壓著部9g與右側緣 部1 A夾住領域，以及被後方延長壓著部9H與左側緣部 1 B夾住之領域，也易於以後方延長壓著部9 9與後方延長 壓著部9H作爲彎曲起點朝向身體方向變形。因此，生理 用衛生棉易於以追隨配合身體之臀部形狀之方式合貼於身 體地變形。 又由於液體引導層5不會重疊到壓著部1 9 0，故易於 形成均等壓縮狀態之壓著部1 90。 於第1圖、第2圖、第7圖、第8圖，以及第1〇圖 所示之各實施形態，由於藉由設置上述液體引導層5，經 血不易擴散於中央吸收領域1 1以外之周圍，故以透液性 之表面薄片形成肌膚側之表面之大致全區域，即使不設置 第9圖或第1 1圖所示之不透液性之薄片22、22或側翼部 2 1、2 1也易於防止經血朝向左右方向側漏。又，如第1 -41 - 1263489 (38) 圖、第2圖、第7圖、第9圖、第10圖，以及第11圖所 示之各實施形態般，即使特別是如第8圖所示於後方部分 不設置較長較寬之護臀部分者，也易於防止經血朝向臀部 方向漏出。 再者，作爲本發明之實施形態之生理用衛生棉，如第 1 2圖（A ) ( B )所示，可作成於生理用衛生棉之肌膚側 表面之左右兩側形成延伸於縱長方向之防漏壁5 0、5 Ο A 之構成。 防漏壁50、50A，是藉由不透液性之薄片22而形成 ，將該薄片22折成2片重疊，藉由在該內側夾有延伸於 縱長方向之彈性構件5 1而形成。第1 2圖（A )( B )， 是顯示將生理用衛生棉在橫向方向基準線Ox處裁斷之狀 態，不過折成2片重疊之上述薄片22，在生理用衛生棉 之縱長方向之兩端部分，其整體被折疊並被接著固定於表 面薄片6。又彈性構件5 1是於縱長方向被拉長成所定之 拉伸度之狀態下被固定於上述薄片22。 藉由彈性構件5 1之收縮力，生理用衛生棉成爲彎曲 形狀，其結果，於比橫向方向基準線Ox前後之所定範圍 內，薄片22立起，形成有上述防漏壁50、5 0A。 藉由設置該防漏壁5 0、5 0 A，更可防止液體之側漏， 又如上述般藉由生理用衛生棉彎曲，會易於合貼於股胯部 〇 又，形成防漏壁50、50A之薄片22，如第12圖（A )所示，亦可從表面薄片6立起，如第1 2圖（B )所示， -42- (39) 1263489 亦可以與表面薄片6同時被捲入下側吸收體3及背面薄片 2間之方式設置。 其次，第1 3圖是顯示製造本發明之生理用衛生棉1 之製造方法之一例。 於布捲1 0 0，捲有用以形成液體引導層5之氣流不織 布等之不織布1 0 1。上述不織布1 0 1，通過第1驅動輥筒 1 〇 2，被供給於加熱單元1 0 3。於該加熱單元1 0 3，設置有 熱風裝置104，從該熱風裝置104之熱風口（不圖示）有 熱風105對著上述不織布101吹。 藉由該熱風1 0 5之吹烘，上述不織布1 〇1恢復膨鬆度 。上述膨鬆度被恢復至1 . 5〜3倍之範圍，又密度被恢復 至〇.〇〇5g/ cm3〜0.02g/ cm3。從上述熱風裝置104吹出 之熱風1 〇5之溫度，在構成氣流不織布之材料中，以在軟 化溫度最低之材料之軟化溫度以上爲理想，又，以軟化溫 度最高之材料之軟化溫度以上之溫度加熱爲更理想。具體 上爲上述加熱溫度在130 t〜300。(：之範圍內。 厚度恢復之不織布1 0 1，在通過第2驅動輥筒1 06之 前段或是後段，或通過之同時，被供給於冷卻裝置1 〇 7。 上述冷卻裝置107是從噴口 l〇7a吹出空氣者，上述不織 布101藉由被空氣吹而急速冷卻。又上述冷卻裝置1〇7， 亦可於不織布1 0 1之表裡兩面以對向之方式設置一對。 若冷卻被加熱而恢復膨鬆度之上述不織布1 〇 1時，由 於形成上述不織布1 0 1之纖維在短時間內被固定化，故可 立即保持上述不織布1 0 1膨鬆度恢復之狀態。因此於其後 -43» (40) 1263489 之搬送時即使立即於上述不織布1 〇 ]加諸張力時，上述不 織布1 0 1之fΜ度也不會被壓扁，於解除張力之同時可立 刻恢復膨鬆度。 特別是’上述不織布1 0 1爲由熱可塑性纖維所形成之 氣流不織布時，構成不織布之材料藉由冷卻下降爲軟化溫 度以下。因此，即使承受上述張力，亦可防止不織布i 〇 1 因伸長而降低膨鬆度。 第1 3圖所不之搬送裝置之場合，設置於加熱單元 103之前段之第1驅動輥筒102之迴轉速度，是以與設置 於上述加熱單兀1 0 3之後段之第2驅動輕筒1 〇 6之迴轉速 度相同或比該速度快爲理想。通過加熱單元1 〇 3之不織布 1 0 1 ’由於在膨鬆度增加之同時，朝向搬送方向之長度會 收縮，故若把在加熱單元1 0 3後段之第2驅動輥筒1 0 6之 迴轉速度，設定得比在加熱單元1 0 3前段之第1驅動輥筒 1 0 2之迴轉速度快，則上述不織布1 〇丨，即使藉由加熱單 元1 0 3暫時恢復膨鬆度，也會受到來自第2驅動輥筒1 0 6 之張力，朝向已收縮之搬送方向再次伸長降低膨鬆度。因 此藉由將上述第2驅動輥筒1 0 6之迴轉速度設定成與第1 驅動輥筒1 0 2相同或比第1驅動輥筒1 〇 2慢，可對上述不 織布1 0 1之長度方向不施加張力，可維持高膨鬆度狀態。 又上述冷卻裝置1 0 7，若設置於供給有不織布1 〇 1之 第2驅動輥筒1 〇 6之前段，則可更易於有效地保持上述不 織布1 0 1之恢復膨鬆度之狀態，更理想。 恢復膨鬆度之上述不織布1 0 1，折疊成例如第3圖所 -44 - 1263489 (41) 示之3片重疊之狀態後，被供給於裁刀輥筒1 Ο 8、1 〇 9之 間，修剪成所定形狀’形成有液體引導層5。該液體引導 層5，被輸送帶吸引並送於輥筒1 1 3、11 4。 於布捲1 1 〇捲有用以形成表面薄片6之氣流不織布等 之不織布1 1 1。上述不織布1 1 1在通過輥筒1 1 2之後，上 述不織布1 1 1以及上述液體引導層5，被夾於輥筒1 1 3、 1 1 4並相互重疊，被供給於透液孔形成輥筒〗i 5、丨丨6間 〇 上述透液孔形成輥筒內，於與形成表面薄片6之不織 布η1對向之側之輥筒1 1 5之表面，設置有加熱之複數個 針頭，另一方面，與液體引導層5對向之側之輥筒1 1 6之 表面爲平滑面。 若重疊之不織布1 1 1及液體引導層5被供給於上述透 液形成輥筒1 1 5、1 1 6間，則加熱之上述針頭會刺入上述 不織布1 1 1，從不織布1 1 1到液體引導層5形成有多數之 透液孔1 5。由於上述不織布1 1 1及液體引導層5包有熱 可塑性纖維，故藉由加熱針頭之刺入，上述熱可塑性纖維 會熔著，於上述透液孔1 5之一部分，不織布1 1 1及液體 引導層5會相互接著。因此於上述不織布丨丨丨與液體引導 層5之交界面不必塗接著劑，不過使上述不織布丨；[1及液 體引導層5通過透液孔形成輥筒1 1 5、1 1 6間之前，亦可 設定將上述不織布1 1 1及液體引導層5間接著之接著製程 〇 於紙漿積層圓筒120之表面，形成上層吸收體4及下 -

The space of the liquid guiding layer is absorbed by the liquid to guide the layer 1263489 (5), and the liquid in the liquid guiding layer is sucked and absorbed by the hydrophilic action and capillary action of the absorbing layer located thereunder. Keep in the absorbent layer. Therefore, when the liquid is repeatedly received in the central absorption region, the movement of the liquid toward the liquid guiding layer can suppress the liquid from remaining on the surface sheet, and the surface sheet can be maintained at a time to easily permeate the liquid. Moreover, since the liquid guiding layer is disposed only in a limited range in the central absorption field, the liquid which is repeated will become mainly penetrated within the above-mentioned limited range in the central absorption field, and can inhibit the liquid of the surface sheet. The diffusion can focus on absorbing liquids. Further, the liquid which is absorbed by the absorption layer and which is to be diffused toward the side surface is prevented by the above-mentioned pressing portion, and it is difficult for the liquid body to move to the absorption layer in the auxiliary absorption field. Therefore, in the auxiliary absorption field, the surface sheet is less likely to be in a liquid-saturated state, and the liquid adhering to the auxiliary absorption area is sucked into the absorption layer located directly below it. Therefore, the liquid diffusion of the surface sheet can be retained in a limited range in the central absorption field, so that the skin is not easily wetted, and since the auxiliary absorption field is maintained at a state in which the liquid can be quickly absorbed, it is easy to prevent the side leakage of the liquid. . Further, it is preferable that the pressing portion is formed so as to continuously surround the predetermined range, and the area surrounded by the pressing portion is used as the central absorption field, and the liquid guiding layer has an area ratio. Any of the small areas of the central absorption field is located at a position that does not overlap the pressing portion. In this way, by the field surrounded by the pressing portion as the central absorption field, the field of penetration of the re-introduced liquid can be limited to the range of the pressing portion. Further, the absorbing layer is provided with a lower layer absorber, and an area of the lower layer absorber which is superposed on the lower layer absorber of the above-mentioned 9- 1263489 (6) is smaller than the upper layer absorber and has an area larger than the upper layer absorber. In the pressing portion, the surface sheet, the lower layer absorber, and the upper layer absorber are pressed into a concave shape 9 to be used in the auxiliary absorption field, and the lower layer absorber is formed in a portion immediately adjacent to the pressing portion. And a high loft portion provided by both of the upper layer absorbers, and a smaller one having a smaller thickness of the lower layer absorber is formed on the outer side of the high loft portion. In this configuration, since not only the central absorption field but also the outer side of the pressing portion is also high in bulkiness, it is possible to widen the high loft area which is in contact with the femoral condyle, and the wearing feeling is good. Further, since the absorption layer in the auxiliary absorption field on the side immediately adjacent to the pressing portion is thick, even if the liquid leaks largely toward the outside of the pressing portion, the liquid can be quickly absorbed. Further, in the central absorption field, it is preferable that a plurality of liquid-permeable holes are formed from the surface sheet to the liquid guiding layer, and chemical fibers forming the surface sheet and the liquid are formed around the liquid-permeable opening. It is desirable that the chemical fibers of the guiding layer are thermally fused. If a liquid permeable hole is formed from the surface sheet to the liquid guiding layer, the liquid accommodating the surface sheet in the central absorbent field becomes apt to penetrate in the field in which the liquid guiding layer is provided. Further, as described above, in order to allow the liquid to be repeatedly transferred to quickly pass through the surface sheet, the fiber density at the time of drying the liquid guiding layer is 〇·005 S / c m 3 or more. 〇 2 g / C m3 or less is ideal. Further, the liquid guiding layer imparts a density of 98 80 Pa (-10-10263489 (7) 10 g / c m2 ) at a pressure of 湿润 in a wet state. 〇 〇 5 g / c m 3 cm3 is ideal. The above-mentioned density range can be adjusted by drawing the liquid guiding layer from the cloth roll and heating the broad bulk. If the liquid guiding layer is subjected to pressure from the body at the above g, the liquid guiding layer is also easily restored when the pressing force is opened. The second sheet of the above-mentioned density allows the liquid to be retained in the gap before the absorption 3 by allowing the repetitive layer to permeate through the surface sheet by its own weight. Therefore, it is easy to prevent _ from becoming a moist state, and the liquid is widely diffused in the surface sheet. The liquid guiding layer functions as a buffer layer for relieving the pressure to be applied in the same manner as the surface sheet, so that the soft feeling is further enhanced and the crucible is more excellent. For example, the liquid guiding layer is an air-through non-woven fabric or an air laid non-woven fabric. Further, the nonwoven fabric may be formed so that the plurality of sheets overlap and the liquid guiding layer is formed. When the non-woven fabric is folded in such a manner that the liquid guiding layer is formed, it is possible to form a high bulkiness in the field of Chiang, and it is possible to make the touch of the central absorbent portion pressed into the painful portion to be softer. In the above invention, it is particularly effective because the menstrual blood is not easily surface-expanded. Also, the central part of the bulge makes it closely follow the form of the female part~0. 0 4 g / ; Reason, can restore the degree range, increase the bulk of the gap. The surface of the liquid absorbing layer is wet, and the skin is folded by the airflow shaping method of the skin. The central absorption and body excretion: Therefore, for I, in recent years, _ Physiological Guard-11 - 1263489 (8 Although the raw cotton is increased, even if the surface is closely attached to the mouth to absorb the menstrual blood, there will be a case where the menstrual blood spreads on the surface. The part of the wearer's body that is not stained by the menstrual blood will feel uncomfortable, or Take time to wipe out the menstrual blood. In the present invention, since the diffusion of the liquid on the surface of the sanitary napkin and the layer close to the surface is very small, the area other than the part of the wearer is less contaminated by menstrual blood. Therefore, the physiological sanitary napkin which is a partial close-contact type of the central bulge is excellent. That is, since menstrual blood does not penetrate and absorb from the mouth, it is less likely to be stained by menstrual blood than the part of the body, and it is not easy to cause discomfort, and the time and effort for wiping the menstrual blood become very small. . Furthermore, when exchanging sanitary napkins, because the menstrual blood seen on the surface is less diffused, the wearer is less likely to experience the so-called sorrow of whether the menstrual blood will be contaminated by the menstrual blood. [Embodiment] FIG. 2 is a plan view showing a surface side of the sanitary napkin 1 as the skin contact surface side of the first embodiment of the absorbent article according to the present invention.

The guiding layer 5, and the laminated structure of the liquid permeable surface sheet 6. The sanitary napkin 1 is formed with a pressing portion 9 that surrounds a predetermined area. As shown in Fig. 2, the crimping portion 9 is provided with a constant width W and extends continuously in a strip shape. The pressing portion 9 includes a right pressing portion 9a and a left pressing portion 9b extending in the longitudinal direction at a position spaced apart from the center line 〇y-〇y in the longitudinal direction by a predetermined distance. The front chamber portion 9c and the rear pressing portion 9d are formed in the lateral direction at a position spaced apart from the front direction by the center line Ox-Ox in the lateral direction. The right pressing portion 9 a and the left pressing portion 9 b , the front pressing portion 9 c and the rear pressing portion 9 d are continuous with each other, and the right pressing portion 9 a and the left pressing portion 9 b are oriented in the longitudinal direction. The curved shape of the center line 〇 y - 0 y is convex, and the front pressing portion 9 c and the rear pressing portion 9 d are curved shapes that are convex toward the center line Ο X - 0 X in the lateral direction. In the embodiment, the pressing portion 9 is in the shape of a left-right symmetry of the -13,263,489 (10) core line Oy-Oy in the longitudinal direction of the interposition, and the center line of the transverse direction is interposed. Symmetrical shape before and after. As shown in Fig. 2, the lower layer absorber 3 is provided with a right side edge portion 3a and a left side edge 邰3b' having a curved shape in which the convex side faces the longitudinal center line Oy-Oy, and has a convex side direction away from the lateral direction. Curve shape in the direction of the center line 〇χ _ The width of the front edge portion 3 c and the trailing edge portion 3 d is wide. The upper layer absorber 4 is provided with a right side edge portion 4a and a left side edge portion 4b having a curved shape in the same direction as the right side edge portion 3a and the left side edge portion 3b, and the front portion and the edge portion 3c are provided. The trailing edge portion 3d has a curved shape of the front edge portion 4c and the trailing edge portion 4d in the same direction, and the shape is substantially similar to the planar shape of the pressing portion 9. Further, the upper layer absorber 4 is wider than the outer circumference of the pressing portion 9 by the rim line 9 B, and has a smaller area than the lower layer absorber 3. In this embodiment, the shape of the lower layer of the lower layer absorber 3 and the shape of the wheel of the upper layer absorber 4 are bilaterally symmetrical with respect to the center line 0 y - Ο y in the longitudinal direction of the interlayer, and the center line Ox-Ox in the transverse direction is interposed. Symmetrical shape before and after. Further, the lower layer absorber 3, the upper layer absorber 4, and the surface sheet 6 are in the entire range of the pressing portion 9, the right pressing portion 9a, the left pressing portion 9b, the front pressing portion 9c, and the rear pressing portion 9d. Pressurized into a concave shape 'this portion is combined with each other. As shown in Fig. 3, the liquid guiding layer 5 is a gas-flow non-woven fabric or the like as described later, and the chemical fibers are followed by each other, and the fibers form a skeleton extending in the three-dimensional direction, and a fine void is formed between the fibers. Density - 14 - 1263489 (11) Non-woven fabric is formed, which is formed by overlapping folds. In this embodiment, the non-woven fabric is folded at two fold lines to form three overlaps. The planar shape of the liquid guiding layer 5 which is folded into three sheets by the non-woven fabric is a rectangle, and the width between the side edges 5a and the side edges 5b extending in the longitudinal direction is indicated by W1, and extends in the lateral direction of the leading edge 5 The length dimension between c and the trailing edge 5 d is indicated by L 1 . As shown in Fig. 2, the area of the liquid guiding layer 5 is much smaller than the area surrounded by the rim line 9A on the inner side of the pressing portion 9, the side edge 5a, the side edge 5b, and the leading edge 5c. And the trailing edge 5d is all inside of the pressing portion 9, and does not overlap the pressing portion 9. In the sanitary napkin 1, the area surrounded by the rim line 9A on the inner side of the pressing portion 9 is the central absorption field 11 . In the central absorption region 11, the lower layer absorber 3 and the upper layer absorber 4 are superposed on the back sheet 2, and the liquid guiding layer 5 which is not covered by the pressing portion 9 is overlapped, and the surface is The surface sheet 6 is covered by the structure. As shown in Fig. 1 and Fig. 4(A), in the central absorption region 11, a plurality of regularly arranged liquid-permeable holes 15 are formed in the surface sheet 6. As shown in Fig. 4(A), the liquid permeable hole 15 is formed by passing through the surface sheet 6 to the liquid guiding layer 5. The surface sheet 6 and the liquid guiding layer 5 contain thermoplastic fibers, and the liquid permeable holes 15 are formed by piercing with a heated needle. At this time, the thermoplastic fibers are fused, and in the portion of the liquid permeable holes 15, The surface sheet 6 and the liquid guiding layer 5 are followed by each other. Therefore, at the interface between the surface sheet 6 and the liquid guiding layer 5, no adhesive is applied, and when the liquid permeates from the surface sheet 6 to the liquid guiding layer 5, it does not occur - 15- 1263489 (12) Reducing the permeation area due to the adhesive The situation. Further, at the interface between the upper layer absorber 4 and the liquid guiding layer 5, the upper layer 7 and the liquid guiding layer are coated by a hot melt type adhesive which is applied in a mesh shape, a comb shape or a spiral shape. 5 then go together. Further, since the upper surface and the lower surface of the upper layer absorber 4 and the lower layer absorber 3 are covered with the hydrophilic fibrous paper, there is no intervening adhesive at the interface between the upper layer absorber 4 and the lower layer. Further, the interface between the lower absorbent body 3 and the back sheet 2 is also followed by a hot melt type adhesive. The area in which the lower layer absorber 3 and the upper layer absorber 4 are present is the auxiliary absorption area 12 than the outer circumference side of the rim line 9B on the outer side of the pressing portion 9. In the auxiliary absorption field 12, a high loft portion 1 2 a in which the lower layer absorber 3, the upper layer absorber 4, and the surface sheet 6 are superposed is formed on the outer peripheral side of the above-mentioned rim line 9 B, in comparison with the outer periphery thereof. On the side, a thinner region 1 2 b whose lower absorbent body 3 is covered by the surface sheet 6 is provided. On the outer peripheral side of the auxiliary absorption field 12, the lower layer absorber 3 and the upper layer absorber 4 are not interposed, and the back sheet 2 and the sheet sheet 6 are followed by a hot-melt type adhesive. As shown in Fig. 1 and Fig. 2, the high loft portion 1 2 a of the auxiliary absorption region 12 is formed so as to surround the outer periphery of the pressing portion 9, and the thickness is thin. The field 1 2 b is formed so as to surround the periphery of the high loft portion 1 2a. Next, an ideal example of each constituent material will be described. The surface sheet 6 is preferably a nonwoven fabric formed of chemical fibers. As the chemical fiber, a polyethylene terephthalate (PET) having a core portion of -16% to 1263489 (13) titanium oxide having a core content of about 5% by mass is used, and the sheath portion is a core of polyethylene (PE). The sheath-type composite synthetic fiber, and the core-sheath type composite synthetic fibers are thermally fused to each other by hot air to be the same. A core-pin type composite synthetic fiber of cerium oxide is added to the above core, and the surface becomes smoother, and the texture of the surface sheet 6 becomes better. Further, when the airflow non-woven fabric is used as the surface sheet 6, since it has a high bulkiness and a void is formed between the fibers, the liquid permeability is good. The core-sheath type composite synthetic fiber forming the surface sheet 6 is hydrophilically treated by a hydrophilic oil agent having a surfactant or the like interposed therein or by coating the surface with the above hydrophilic oil agent. It is preferable that the chemical fiber is mixed with a water-repellent fiber coated with a water-repellent oil agent on its surface. By mixing the water-repellent fibers, there is an effect of preventing the liquid from diffusing on the surface sheet 6. Further, when the water-repellent fibers are mixed, as shown in Fig. 4(A), a plurality of liquid-permeable holes 15 are formed in the surface sheet 6, and it is preferable to use a structure in which the liquid easily permeates the surface sheet 6. The above water-repellent fibers are preferably contained in a mass ratio of 5 to 30% by mass to the surface sheet 6. If it exceeds 30%, it becomes easy for the liquid to bounce off the surface of the surface sheet 6, and the liquid permeability of the surface sheet 6 is lowered. If it is less than 5%, the effect of preventing liquid diffusion will be reduced. Further, the surface sheet 6 may be a point bond nonwoven fabric formed of a chemical fiber, a spunbond nonwoven fabric, or a hydrophilic fiber such as a crucible, and a water needle containing the water-repellent fiber (s P u η 1 ace ) Not woven. Alternatively, a resin film having a plurality of liquid permeable holes or a laminate of a resin film and a non-woven fabric may be formed into a plurality of liquid permeable holes. -17-(14) 1263489 are all preferably in the range of 15 to 60 g/m2 based on the basis weight of the surface sheet 6. If it is less than the above range, sufficient surface strength cannot be obtained, and damage occurs in the wet state. Further, if it exceeds the above range, the surface sheet 6 becomes stiff and there is a feeling of discomfort during wearing. Further, the density of the surface sheet 6 is at 0. Below 1 2 g / cm3 is ideal. Since the menstrual blood viscosity is high in women's physiology, in order to infiltrate the menstrual blood, the density is preferably below the above-mentioned enthalpy. Further, the permeate hole 15 is as shown in Fig. 4 (A) and Fig. 6, and the opening size Hd of the surface is 0. 5~2. 0 mm, the arrangement pitch Hy in the longitudinal direction is 2 to 5 mm, the arrangement pitch Hx in the lateral direction is 1 to 4 mm, and Hy is longer than Hx, and the arrangement of the liquid-permeable holes 15 is as shown in Fig. 6, each liquid-permeable hole 1 5 is a position in which the positions are shifted from each other in the X direction and the Y direction. The liquid guiding layer 5 is a structure having a hydrophilic chemical fiber, for example, a buffering surfactant or a chemical fiber coated with a surfactant on the surface, and indirectly forming a three-dimensional skeleton and having a void. Thus, by using the liquid guiding layer 5 having a void, it becomes easy for the liquid to permeate through the surface sheet 6 and enter the space by its own weight, and the liquid can be held before being absorbed to the absorbent layer located thereunder. In the gap. As the above-mentioned structure, a gas permeable non-woven fabric having a liquid permeable function formed of a hydrophilic chemical fiber or a gas permeable non-woven fabric having a liquid permeable function and a liquid retaining function can be used. The airflow non-woven fabric is a core-sheath type composite synthetic fiber in which the core portion is polypropylene (p p ) and the sheath portion is polyethylene (P E ) in an eccentric form (for example, -18-(15) 1263489 has a fineness of 4. The fiber layer of 4 dtex (fiber length: 50 mm) was thermally fused with the sheath portions of the above-mentioned core-sheath type composite synthetic fibers by using hot air. Or the airflow non-woven fabric is a core-sheath type composite in which the core portion is a polyethylene terephthalate (ρ Ε τ ) containing about 1.1% by mass of titanium oxide, and the sheath portion is polyethylene (PE). Synthetic fiber (for example, the fineness is 2. A fiber layer of 2dtex fiber length of 44 mm) is obtained by heat-sealing the sheath portions of the core-sheath type composite synthetic fibers with hot air. The density of the airflow non-woven fabric which can be used as the liquid guiding layer 5 is 0. 005g / cm3 or more 0. In the range of 1 g/cm3, it is preferable to heat-treat the airflow non-woven fabric which is pulled out from the cloth roll to restore the looseness as described below, and to use it as the liquid guiding layer 5. For example, in the above-mentioned airflow non-woven fabric, heat treatment can be performed by 115 ° C to 300 ° C, more preferably 130 ° C to 200 ° C (for example, 1 minute temperature of 1 35 ° C hot air treatment) The thickness of the above airflow non-woven fabric is restored to 1. 2 to 4 times the range. Preferably, the airflow non-woven fabric is subjected to heat treatment to restore bulkiness, and then the airflow is not cooled. Thereby, the bulkiness which is recovered by the heat treatment and the bulkiness are maintained by quenching can produce a low-density cushioning airflow non-woven fabric. The density of the airflow non-woven fabric after the recovery of the bulkiness is lower than that of the upper absorbent core 4 and the surface sheet 6, so that the density in the dry state is used again. 〇〇5g/ cm3 or more 0. The range of 02g / cm3 is ideal. If the density is less than the above range, the gap between the fibers becomes too small, and it becomes difficult for the liquid to be -19-1263489 (16) to permeate through the surface sheet 6 and enter the above space by its own weight, and the menstrual blood is directed from the surface sheet 6 toward the upper layer. The guiding function of the absorber 4A is deteriorated. Further, if it exceeds the above range, the void becomes too large, and the strength of the skeleton extending in the three-dimensional direction of the fiber is lowered, and it becomes easy to be crushed by the pressure of the body. After the bulkiness is restored, the airflow is not woven, and the density at a pressure of 980 Pa (10 g/cm2) is given in a wet state to 0. 005g/ cm3~0. 0. Ideally within the range of 4g/cm3. Moreover, the thickness of each of the airflow non-woven fabrics after the bulkiness is restored is in a dry state and a wet state. 5 mm to 3 mm, preferably 2 mm to 3 mm. Further, the thickness at which the pressure of 98 ° Pa (10 g/cm 2 ) is applied in a wet state is 0 · 5 m 2 to 2 m m, preferably 0. 5 m m~1 . 5 m m. Further, the recovery ratio of the thickness after the pressure is removed is preferably 1 · 5 times or more, more preferably 1 · 8 times or more, as 1 when pressurized. It is preferable to form the liquid guiding layer 5 by laminating the above-described air flow non-woven fabric into a plurality of sheets. Further, the measurement of the thickness and density in the dry state and the wet state, and the thickness and density in the wet state and the application of the above pressure are based on the measurement method described in (1) of (Example B) below. When the liquid guiding layer 5 is used, when the menstrual blood is continuously received and the body pressure is applied, a space can be maintained in the liquid guiding layer 5, and the liquid can be guided and held in the liquid guiding layer 5 to prevent liquid. The liquid is rewound towards the surface sheet 6. Moreover, when the body pressure is reduced, the bulkiness can be restored immediately, and the liquid permeable function of the liquid which is repeated can be maintained for a long time. Further, the basis weight of the liquid guiding layer 5 as a whole is in the range of - 20 - (17) 1263489 of 15 to 300 g/m2, more preferably 20 to 1 0 0 g / m 2 . As long as it is within the above range, the liquid in the liquid guiding layer 5 can be moved toward the absorbent layer, and the liquid can be held in the gap in the liquid guiding layer 5 before the liquid is absorbed in the absorbent layer. The air-laid nonwoven fabric used as the liquid guiding layer 5 is obtained by mixing the hydrophilic natural fiber or the regenerated cellulose fiber and the chemical fiber 'with the thermoplastic resin fiber in the air, and recycling the fiber to the net. After the upper layer is laminated, heat treatment is performed to melt the surface of the thermoplastic resin fiber, and the thermoplastic resin fiber and the hydrophilic fiber are thermally fused. For example, as the hydrophilic fiber, wood pulp, enamel, barium acetate, natural cellulose fiber other than pulp, cellulose alkalized pulp, crosslinked pulp, or the like can be used, and as the chemical fiber, the core can be used as polypropylene (PP). And the sheath is a core sheath fiber of polyethylene (PE) (for example, a fineness of 1. 7dtex, fiber length is 13mm). Further, the above-mentioned fibers may be formed by a resin adhesive agent in the form of a latex, a flow-formable nonwoven fabric, a chemical fiber, or a hydrophilic fiber and a chemical fiber bonded to each other, and a three-dimensional skeleton structure having a void-forming structure. . When the air-laid nonwoven fabric is used as the liquid guiding layer 5, it is provided with a liquid permeable function in which the liquid enters the void by its own weight, and contains hydrophilic fibers such as natural fibers or regenerated cellulose fibers. The liquid inhalation guiding layer 5 to be retained in the surface sheet 6 can be held by the action of water. Further, the air stream is formed into a non-woven fabric, and after being pulled out from the cloth roll, it is heat-treated at a heat of 1 〇 〇 to 3 〇〇 ° C, preferably 130 to 20,000 volts! Minutes or so, -21 - 1263489 (18) Restoration of bulk is ideal. When the nonwoven fabric is formed by air flow, the density at the time of drying, the density at the time of wetting and pressurization, the thickness of one sheet of non-woven fabric, the thickness at the time of wetting and pressurization, the recovery rate of the thickness when the pressure is removed, and the base The ideal axis 重 of the weight is the same as the airflow non-woven fabric described above. Further, in the liquid guiding layer 5, a nonwoven fabric which is processed by a method such as a needle punching method or a highloft method, and which is subjected to heat treatment to restore bulkiness, or may be used without being woven, may be used. A material having a three-dimensional skeleton and recovering bulk by heat, such as urethane or the like. Further, the liquid guiding layer 5 may be formed by the above-mentioned air flow non-woven fabric or air flow forming non-woven fabric which is heat-treated to restore the bulkiness. However, the liquid guiding layer 5 may be partially heat-treated to have a portion having a restored bulkiness. And those who did not restore the bulkiness. For example, when the liquid guiding layer 5 having a long dimension in the longitudinal direction is used, only the portion opposite to the cornice may be heat-treated to have a low density, and the portion opposite to the rear anus or gluteal groove may be formed. Then, the bulkiness is not restored to a state higher than the density of the front portion. By this, in the part opposite to the mouth, the large amount of menstrual blood can be quickly moved to the absorption layer in a short time, and then the surface portion can be subjected to less by the prior density. The amount of liquid is quickly inhaled. Or conversely, the front portion may not be heat treated, only the rear portion is heat treated, and the rear portion is made low density. The fineness of the fibers constituting the liquid guiding layer 5 is as long as 1. 8 to 3 3 dt ex, in order to restore the bulkiness when the pressure from the body is opened, and to make it difficult to cause liquid backflow (reflow phenomenon-22- 1263489 (19)), The fineness is at 2. 4 to 1 1 dtex is ideal. Further, the liquid guiding layer 5 is used by folding the above-mentioned nonwoven fabric into three sheets. Here, when one piece of non-woven fabric is produced and the basis weight of the non-woven fabric which is superposed on three sheets is the same, the fiber density is increased, the thickness is reduced, and the internal void is also small. Therefore, the function of the above-mentioned liquid guided in the above-mentioned void by its own weight is lowered. Further, as shown in Fig. 3, the two fold lines folded into three sheets of non-woven fabric are oriented in the longitudinal direction, and if the two fold lines are respectively located at the side edges 5a and the side edges 5b of the liquid guiding layer 5, they are folded into Each of the three overlapping layers becomes easy to move in the left-right direction of FIG. 3 at the interface between the layers. That is, the liquid guiding layer 5 can hold a degree of freedom in the left-right direction, and the liquid guiding layer 5 can relatively freely move in accordance with the movement of the body in a state in which the central absorbent field 11 is closely followed by the mouth. Therefore, it is possible to maintain the tightness of the area in which the liquid guiding layer 5 is provided and the above-mentioned mouthwash at any time, and the mouth is less likely to be less uncomfortable. The number of layers formed by the folding of the liquid guiding layer 5 by the non-woven fabric is not necessarily limited to three overlapping sheets, and may be two sheets overlapping or four sheets overlapping or more. If the liquid can enter the gap between the layers of the non-woven fabric when the number of overlapping sheets is large, the liquid received by the plurality of surface sheets 6 can be guided to the liquid guiding layer 5. However, if the number of times of folding is too large, the number of processes for forming the liquid guiding layer 5 will increase, and the productivity will be lowered. If the number of overlapping sheets is large, the gap between the layers will become too large, and liquid will remain in the portion. Therefore, as the number of folding of the non-woven fabric, it is considered from the point of guiding function of liquid and production efficiency, and it is desirable to overlap two sheets or even five sheets. However, as described above, in order to have the degree of freedom in the direction of the left and right -23 - 1263489 (20) directions of the layers of the non-woven fabric, and to form an appropriate number of interfaces between the layers, it is preferable to form three sheets of overlap. Further, as the liquid guiding layer 5, a non-woven fabric cut into a size of W1xL1 may be formed, for example, by three sheets. Such overlap can give the same degree of freedom in density or layer as the above-mentioned folder. However, in order to prevent the liquid guiding layer 5 from being caught in the pressing portion 9, the non-woven fabric must be cut in such a manner that the above-mentioned wide size W is a very small size, but it is very necessary to cut the non-woven fabric into such a small size. Difficult, it is therefore desirable to fold the non-woven fabric into the liquid guiding layer 5 of the size of WlxLl. The upper absorbent body 4 is formed of a laminate of pulp of pulverized pulp, cellulose alkalized pulp, crosslinked pulp, and the like, and has a basis weight of, for example, 23 g/m2. The lower absorbent body 3 is used in combination with the above pulp. 5~2. 0% by mass of the superabsorbent polymer, and the basis weight and thickness are 80% or less of the above-mentioned upper layer absorber 4, for example, a basis weight of 160 g / m2. Further, the upper absorbent core 4 and the lower absorbent core 3 are used in a state in which the upper and lower absorbent cores 4 and the lower absorbent core 3 are sandwiched by the fiber paper. Further, in the lower layer absorbent body 3, embossing of the lattice pattern 15 shown in Fig. 1 is formed. The density of the upper layer absorber 4 and the lower layer absorber 3 is at 0. 1~0. The range of 6g/cm3 is ideal. If it is less than the above range, the rigidity will become too low to maintain the shape of the sanitary napkin 1, and there will be creases or distortions when worn on the body. If it exceeds the above range, it will become stiff and easily cause discomfort to the body. However, by forming the embossing of the lattice pattern in the lower absorbent body 3 as described above, the lower layer absorbs -24 - 1263489 (21) and the density of the body 3 is higher than that of the upper layer absorbent body 4 within the above range of the density. Moreover, in order to make the liquid guided by the liquid guiding layer 5 easy to be attracted by the upper layer absorber 4, the density of the upper layer absorber 4 is preferably twice or more, more preferably 5 times the density of the liquid guiding layer 5. the above. Further, the back sheet 2 is a liquid-impermeable and air-permeable sheet, and is a polyethylene (PE) film or a polypropylene (PP) film in which fine vent holes are formed. For example, by mixing the inorganic ruthenium of CaC03, BaS04 or the like in the above-mentioned plastic sheet and extending it, a fine vent hole which is appropriately dispersed is formed on the film, and the air permeability is improved, and the thickness is 15 to 5 G. //m or so. Alternatively, it may be a material in which a thermoplastic resin is laminated on a nonwoven fabric. As shown in Fig. 3, on the outer surface of the back sheet 2, a pressure-sensitive adhesive layer 7 having a strip shape extending continuously in the longitudinal direction is applied to a predetermined lateral width. On the other hand, in the state before use, the pressure-sensitive adhesive layer 7 is covered and protected by a release sheet (not shown). The crimping portion 9 is in a state in which the lower layer absorber 3, the upper layer absorber 4, and the top sheet 6 are overlapped by the embossing process using the heating roll, and the surface is smoothed on the outer surface of the lower layer absorber 3. The roller is in contact with the surface of the surface sheet 6 by a heating roller having a convex portion having an embossed pattern, and the lower layer absorber 3, the upper layer absorber 4, and the surface sheet 6 are pressurized and heated by the convex portion. As a result, in the crimping portion 9, the wide portion having the wide size as shown in Fig. 2 is a portion (5), and the thermoplastic fibers contained in the respective layers and sheets are melted to form a film-like molten portion 9D. Between the portions 9D, the high-density portion 9 E having a higher density than the region of the pressing portion 9 is formed, but the layer is formed in the above-mentioned three layers. The pressing portion 9 is provided with a back sheet 2 on the lower side of the lower layer absorber 3. In this embodiment, the melting portion 9D is formed obliquely to the direction in which the pressing portion 9 extends. The width dimension of the above-mentioned melting portion 9D (5 is, for example, 0. 2~1. 5 m m, the distance P between the above-mentioned melting portions 9 D is, for example, 1 to 5 m m. Further, the width dimension W a of the pressing portion 9 is about 2 to 4 m m. As described above, in order to appropriately form the molten portion 9D and the high-density portion 9E, the temperature of the heating roller is set to be above 120 °C, and the pressure between the rolls is in the range of 98 to 2450 Pa. The choice is ideal. When the crimping portion is formed at the above temperature and pressure, when the pressure is applied to the thigh from both sides after the undergarment is attached to the body, as shown in Fig. 5, the pressing portion 9a is pressed to the right side of the pressing portion 9. And a part of the left pressing portion 9b, the sanitary napkin 1 becomes easy to bend. Further, there is no problem that the pressure at which the embossing is formed is too high and a part of the melted portion 9D is broken. Further, as described above, in the central absorption region 1, the respective edge portions of the liquid guiding layer 5 are located further inside than the pressing portion 9, and the liquid guiding layer 5 is not superposed on the pressing portion 9. When the liquid guiding layer 5 is superposed on the pressing portion 9, since the non-woven fabric forming the liquid guiding layer 5 is a three-dimensional skeleton having a high bulkiness and formed of fibers, the pressing strength of each of the sheets of the pressing portion 9 is obtained. Will decrease. At this time, the surface sheet 6 and the upper layer absorber 4 in the pressing portion 9 become unfixed or fixed, and the menstrual blood received in the central absorption field 11 diffuses along the surface sheet 6 or in the upper layer absorber 4 At the time of internal diffusion, -26 - 1263489 (23) becomes unable to prevent the diffusion of the liquid at the pressing portion 9. Further, when the pressing strength of the pressing portion 9 is weak, it is difficult to cause the central absorption region 1 1 to be convexly deformed toward the body side, and in the central absorption region u and its periphery, the sheets are displaced and staggered, and it is easy to The surface sheet 6 or the liquid guiding layer 5 is twisted. As a result, it becomes difficult for the central absorption field to closely follow the enthalpy, and it is impossible to achieve the initial purpose of absorbing liquid in the central absorption field. From the above, it can be seen that the central absorbent region 11 is deformed toward the body by the liquid guiding layer 5 without overlapping the pressing portion 9, so that the central absorbent region 11 can be softly closely attached to the cornice. Further, the pressing portion 9 can function to prevent liquid from diffusing. Hereinafter, the ideal size of each part will be described. The sanitary napkin 1 of the first embodiment is a general size used in the daytime, and the width dimension of the center line Ο X - Ο X in the lateral direction is 80 mm, and the center line in the longitudinal direction is 0 y - 0 y. The length is about 210mm. Further, the central absorption area 1 1 surrounded by the pressing portion 9 must have an area which can be closely attached to the female gargle, the wide size W2 is in the range of 25 mm to 50 mm, and the longitudinal direction dimension L1 is 50 to 110 mm. The scope. Further, in the elongated form suitable for night wear shown in Fig. 8, the central absorption area 1 1 is preferably extended to the rear of the anus. The upper limit of the longitudinal dimension of the central absorption field 1 1 at this time is 2 8 0 mm or so. The wide dimension W1 and the longitudinal dimension L1' of the liquid guiding layer 5 are set corresponding to the area of the central absorption region 1 1 , but the edge of the liquid guiding layer 5 is pressed and pressed at the liquid -27-1263489 (24). The gap between the 9A of the inner side of the section 9 must be separated by a certain degree. For example, the edge of the liquid guiding layer 5 is spaced apart from the above-mentioned rim line 9 A, that is, (W 2 - W 1 ) / 2, and (L 2 - L 1 ) / 2, in the range of 1 〜] 〇 mm The range is ideal, more preferably 2 to 6 mm. In the above range, when the crimping portion 9 is formed, the edge portion of the liquid guiding layer 5 does not overlap the pressing portion 9. In the above embodiment, the width dimension of the center line 〇x-Ox in the lateral direction of the layer absorber 4 is about 55 mm, and the length dimension of the center line 〇y-〇y in the longitudinal direction is about 120 mm. Further, the lower absorbent body 3 has a width of about 75 mm and a length of about 180 mm. Further, the wide size WB of the high loft portion 1 2 a in the auxiliary absorption field shown in Fig. 3 is preferably about 3 to 10 mm. When the sanitary napkin 1 is used, the release sheet of the protective pressure-sensitive adhesive layer 7 is first peeled off, and the adhesive pressure-sensitive adhesive layer 7 is interposed, and then used inside the lower portion 20 of the undergarment. In the state in which the underpants and the sanitary napkin 1 are worn on the body, the crotch portion 20 and the sanitary napkin 1 are subjected to a tight force from the thigh portions on both sides. In the sanitary napkin 1 described above, the right pressing portion 9a and the left pressing portion 9b extending in the longitudinal direction are formed at positions equidistant from the longitudinal direction center line 0 y - 0 y in the lateral direction. According to the above tightening force, the portion of the right side pressing portion 9a and the left side pressing portion 9b of the sanitary napkin 1 exhibits its function as a hinge, and the sanitary napkin 1' is used as the portion of the hinge The fold line is bent as shown in Fig. 5 - (25) 1263489 In particular, the liquid guiding layer 5 provided in the central absorbent field 11 does not overlap the pressing portion 9, and the pressing portion 9, the lower layer The absorber 3 and the upper absorber 4 are present only thereon. Therefore, the rigidity difference and the thickness difference between the pressing portion 9 and the region other than the pressing portion 9 can be made large, and the sanitary napkin 1 can be easily formed on the right side pressing portion 9a and the left side. The pressing portion 9b is bent at a position. At this time, the tight force from the thigh portion acts on the central absorption region 11 from the right pressing portion 9a and the left pressing portion 9b, and the surface of the central absorption region 11 faces the body by the tightening force. The convex curvature, which is located on the surface of the surface sheet 6 of the central absorbent field, tends to closely follow the female's mouth. At this time, the central absorption region 11 has a high bulkiness including the lower absorbent core 3, the upper absorbent core 4, and the liquid guiding layer 5, and since the liquid guiding layer 5 is a material having a low density, the mouth is closed. The touch is softer. The menstrual blood excreted from the fistula and the like have a higher viscosity than the liquid, and are mainly received by the central absorbent region 1 1 of the surface sheet 6, and the liquid permeated through the surface sheet 6 is received by the liquid guiding layer 5. That is, since the liquid guiding layer 5 is provided with a structure in which the chemical fibers are joined and has a skeleton extending in the three-dimensional direction to form a void, the liquid permeates through the surface sheet 6 by its own weight, and is guided to the above liquid guiding. Within the void of layer 5. Further, the liquid absorbed in the liquid guiding layer 5 is attracted by the hydrophilic action and capillary action of the upper layer absorber 4 having a higher density, and is absorbed and held by the upper layer absorber 4. Further, the liquid absorbed by the upper absorbent body 4 is absorbed and held by the lower layer absorbent body 3. -29- (26) 1263489 The liquid guiding layer 5 described above has a high ability to move the liquid downward, and before the liquid is sucked into the upper absorbent body 4, since the liquid is held in the liquid guiding layer 5, the surface sheet 6 Not easily liquid saturated. Therefore, the surface sheet 6 does not easily make the skin feel moist. Further, when the seat posture or the like is exerted by the pressure of the body weight, the pressing force is received by the surface sheet 6 and the liquid guiding layer 5. Since the liquid guiding layer 5' is a low-density layer which restores bulkiness by heat treatment, it functions as a buffer layer. Further, even when the liquid guiding layer 5 is compressed by the pressure from the body, the high void ratio can be maintained, so that the liquid from the surface sheet 6 can be temporarily held and the liquid can be sucked into the upper absorbent body for a long time. The function. When the pressure of the body is increased, the pressure of the liquid guiding layer 5 is high. Therefore, the liquid guiding layer 5 is continuously formed with a gap. The surface sheet 6 contains water-repellent fibers, whereby the diffusion of the liquid can be prevented. However, since the surface sheet 6 can maintain the bulkiness as described above, it is easy to maintain a state in which voids are formed therein, so that even the above-mentioned water-repellent fiber is contained. The liquid permeable function of the surface sheet 6 can also be fully utilized. In this embodiment, as shown in Fig. 4(A), since a plurality of liquid pervious holes 15 are formed from the surface sheet 6 to the liquid guiding layer 5, the liquid received on the surface of the surface sheet 6 permeates the above. The liquid permeable hole 15 moves to the liquid guiding layer 5. Therefore, the liquid received by the surface sheet 6 is liable to be lowered by the weight of the liquid guiding layer 5, whereby it is easier to prevent the liquid from remaining on the surface sheet 6 or the diffusion of the liquid. Thus, in the physiological fei raw cotton 1 'concentrated and repeatedly excreted in the central suction -30 - 1263489 (27) the liquid in the central portion of the field 1 1 will penetrate the surface sheet 6 and be received by the liquid guiding layer 5 to become a liquid It is not easy to spread on the surface sheet 6. Further, since the density of the liquid guiding layer 5 is low, the liquid in the liquid guiding layer 5 is prevented from diffusing toward the periphery, whereby the diffusion of the liquid into the surface sheet 6 can be suppressed. The liquid that has permeated through the surface sheet 6 and the liquid guiding layer 5 is absorbed and diffused in the upper layer absorber 4, and is absorbed and diffused by the lower layer absorber 3. However, in the central absorption field 1, since the distance between the upper absorbent body 4 and the surface sheet 6 is relatively large, the color of the menstrual blood diffused in the upper absorbent body 4 is not easily visually confirmed from the surface side. Thus, the diffusion of the liquid in the surface sheet 6 is limited, and since the liquid in the upper layer absorber 4 is diffused, it is invisible from the surface side, so that it is easy to prevent the wearer from using the surface of the visual sanitary napkin 1 during use. I am upset. Further, when the liquid is diffused toward the periphery in the upper absorbent body 4 and the lower absorbent core 3 in the central absorbent region 11, the pressing portion 9 functions to prevent the liquid from diffusing. In other words, the liquid which is diffused in the lateral direction along the upper layer absorber 4 and the lower layer absorber 3 to the right side pressing portion 9 & and the left side pressing portion 9 b is concentrated in the high density portion 9E and then flows to the high density portion. The space between the 9E is conducted along the right pressing portion 9a and the left pressing portion 9b in the longitudinal direction. Therefore, it is difficult for the liquid received by the central absorption field 11 to pass through the auxiliary absorption field 12 of the pressure portion 9 to the periphery. In the outer periphery of the central absorption field 1 1 , an auxiliary absorption field 1 2 ' is provided. However, as shown in FIG. 4 (B ), a thick and high loft portion exists on the outer side of the pressing portion 9 2a As shown in Fig. 5, in the state of deformation -31 - (28) 1263489, the above-mentioned high loft portion 1 2 a is easily attached to the underarm portion of the outside of the labia majora. Further, as shown in Fig. 5, since the crimping portion 9 is simultaneously buried between the central absorbent region 1 1 having a high bulkiness and the high bulk portion 1 2 a, the crimping portion 9 having a high density and high rigidity is not Will directly contact the body, pressing the part 9 will not give the body a straightforward feeling. When the menstrual blood flowing along the femoral condyle adheres to the field of auxiliary absorption, the blood flowing through the surface of the central absorption field 11 is attached to the surface of the auxiliary absorption field 12 The liquid, which is absorbed by the capillary action of the capillary acting on the upper layer of the absorber 4 directly below the surface sheet 6, is rapidly permeated through the surface sheet 6 and absorbed by the upper layer absorber 4. As described above, since the liquid absorbed by the upper absorbent core 4 or the lower absorbent core 3 in the central absorbent region 11 is less likely to pass over the pressing portion 9 to the outside thereof, the upper absorbent core 4 in the auxiliary absorbent region 12 is The lower absorbent body 3 is less likely to be saturated by a large amount of liquid. Further, in the auxiliary absorption field, the lower layer absorber 3 and the upper layer absorber 4 are provided at the position of 2, and the volume of the material of the absorption layer is increased. Therefore, the liquid adhering to the surface of the surface sheet 6 in the auxiliary absorption field 12 is immediately absorbed by the lower absorption layer, and it is easy to prevent the side leakage of the liquid. Further, in the auxiliary absorption field 12, the upper layer of the surface sheet 6 has a higher density of the upper layer absorber 4, and the liquid adhering to the surface of the surface sheet 6 is rapidly attracted by its hydrophilic force and capillary action. In the field of auxiliary absorption 12, it is not necessary to provide a liquid permeable hole in the surface sheet. However, a liquid permeable hole may be formed in the surface sheet 6 of the auxiliary absorption field 12. -32- 1263489 (29) The lower layer absorber 3 is provided in a wide range in the central absorption field 1 1 and the auxiliary absorption field 1 2, and the lower layer absorber 3 has a basis weight and a small thickness, and is provided internally. Since the polymer is highly absorbing, the liquid holding capacity of the lower absorbent body 3 becomes large. Therefore, in the central absorption field and the auxiliary absorption field I 2, the lower absorption body 3 becomes a liquid which can be kept much as the whole of the sanitary napkin 1 and becomes a liquid absorption capacity as described above. In the above-mentioned sanitary napkin 1, the central absorbent region 11 is formed by the central portion of the pressing portion 9 to be easily attached to the mouth, and the central absorbent region 11 is mainly for receiving liquid. On the other hand, in the central absorption region 1, the surface sheet 6 is less likely to be saturated with respect to the repeated supply of the liquid, and the liquid on the surface sheet 6 is less likely to diffuse. However, in the event that the liquid exceeds the central absorption field 11 and adheres to the auxiliary absorption field 12, the liquid will be captured immediately in the auxiliary absorption field. Table 7 to Figure 11 show another embodiment of the present invention. In the above-described embodiments, the same components as those in the first embodiment are denoted by the same reference numerals as in the first embodiment, and the detailed description is omitted. Fig. 7 is a plan view showing a sanitary napkin 1 A as an absorbent article according to a second embodiment of the present invention. In the sanitary napkin 1 A, only the pattern of the pressing portion 9 is different, and the other configurations and dimensions are the same as those of the physiological cotton 1 shown in Figs. 1 to 5 . In the sanitary napkin 1a shown in Fig. 7, only the right pressing portion 9a and the left pressing portion 9b are formed as the pressing portion, and the physiological use shown in Fig. 33-(30) 1263489 is not formed. The sanitary napkin 1 has a front pressing portion 9c and a rear pressing portion 9d. The structure of the right crimping portion 9a and the left pressing portion 9b is the same as that of the above-described physiological sanitary napkin shown in Figs. 1 and 2 and the like. In the sanitary napkin 1 A, since the right side pressing portion 9a and the left side pressing portion 9b extending in the longitudinal direction are also provided on the left and right sides, the deformation state when wearing the femoral condyle portion is the same as that of the fifth figure. the same. Further, the physiological cotton 1 A 'the area sandwiched by the right pressing portion 9 a and the left pressing portion 9 b is the central absorption region 1 1 A, which is at the right outer side than the right pressing portion 9 a And the auxiliary absorption area 1 2 A is formed at the left outer side than the left pressing portion 9b. The guiding function or the absorbing function of the liquid in the central absorption field 1 1 A and the auxiliary absorption field 1 2 A is the same as the central absorption field Π and the auxiliary absorption field 1 of the above-mentioned physiological sanitary napkin 1. Also, the 'Ghai physiological cotton 1 A is also a shape that is symmetric about the center line of the longitudinal direction 〇 y - 0 y, and the center line Ο X - Ο X in the transverse direction is symmetrical. Further, the length dimension LB from the lateral direction center line Ox-Ox to the right front pressing portion 9a and the left pressing portion 9b is longer than the length dimension LA from the lateral direction center line to the liquid guiding layer 5 leading edge 5c. long. The length dimension from the center line in the lateral direction to the rear end of the right pressing portion 9a and the left pressing portion 9b, and the length dimension to the trailing edge 5d of the liquid guiding layer 5 are also the same. Further, the above Lb-La is preferably 3 mm or more, more preferably 5 mm or more. With such a configuration, the liquid received by the central portion of the central absorption region 1 1 A is interposed from the surface sheet 6 by the liquid guiding layer 5 by the upper layer absorber 4 - 34 - 1263489 (31) and the menstrual blood absorbed by the lower layer absorbent body 3 When diffusing toward both side surfaces of the respective absorbers 3 and 4, the diffusion can be prevented by the right pressing portion 9a and the left pressing portion 9b, and the respective absorbers 3 and 4 located in the auxiliary absorption region 1 2 A can be prevented. It is not easy to be saturated with liquid. Fig. 8 is a plan view showing a sanitary napkin 1 B as an absorbent article according to a third embodiment of the present invention. The sanitary napkin 1B has the same basic structure as the above-described physiological cotton 1 and 1 A and 1 D, but differs only in the overall size and the shape of the flat pattern of the pressing portion. The sanitary napkin 1B has a longer dimension in the longitudinal direction and a wider width direction in the rear, and the rear portion becomes a so-called hip protector that can be closely attached to the buttocks when worn on the femoral condyle. . In the sanitary napkin 1 B, the back sheet, the lower layer absorber 3 A, the upper layer absorber 4A, and the liquid guiding layer 5A have a long dimension in the longitudinal direction. Further, the pressing portion 90 is also in a form in which the longitudinal direction is long. The vertically-shaped crimping portion 90 has a right pressing portion 90a, a right pressing portion 90b, a front pressing portion 9〇c, and a rear pressing portion which are continuously formed so as to surround the central absorption region 1 1 B. Department 90d. Further, a pair of front extension pressing portions 90e and 90f are provided further forward than the front pressing portion 90c. The front extension pressing portions 90e and 90f are obliquely extended so as to be wider toward each other in front, and the front end portions of the front extension pressing portions 90e and 9 Of are located at positions where the physiological sanitary napkins are separated from each other. . Further, a shorter inner pressing portion 90g is provided on the inner side of the right pressing portion 90a, and a lower inner side than the right pressing portion 90b is also provided -35 - 1263489 (32) having a short inner pressure The Ministry is 9 0 h. Further, as shown in Fig. 8, each of the portions of the pressing portion 90 has a predetermined width, but in the wide width, the film-like melting portion 9D is the same as that of the embodiment shown in Fig. 2 . The high-density portion 9E is alternately formed along the line direction of the pressing portion. Further, the liquid guiding layer 5A is provided in the central absorption region 1 1B so as to have a long area in the longitudinal direction, and is provided so as not to be heavy K to the pressing portion 90. On the outer circumference of the pressing portion 90, an auxiliary absorption region 12B is formed. In the sanitary napkin 1B, since the central absorbent field 1 1 B is long in the longitudinal direction, the central absorbent field 1 1 B can be attached to the buttocks from the mouth. The pattern shape of the pressing portion 90 is such that the sanitary napkin is easily bent at a portion of the pressing portion 9 Oe or 9 Of in the front, so that the sanitary cotton can be easily attached to the vicinity of the shame in front of the mouth. In addition, since the front side of the central absorption area 1 1 B and the rear area are easy to bend with the inner pressing portion 90 h and 90 g as the starting point, the field in the center of the absorption field 1 1 B is easily attached to the cornice. The rear area is easy to fit in the groove of the buttocks. And because the menstrual blood carried by the surface sheet 6 A can be guided to the lower layer absorber 4 A and the lower layer absorber 3 A by the liquid guiding layer 5 A located in the central absorption field Π B, the central absorption field 1 The menstrual blood received by 1 B is not easily spread along the surface sheet 6 from the central absorption field 丨 B beyond the pressing portion 90 toward the periphery. Therefore, even if the length of the physiological cotton 1 B, that is, the length of the longitudinal direction of the buttocks or the width of the transverse -36-1263489 (33) direction is small or thin, it is easy to prevent menstrual blood. Leaked in the direction of the direction. Further, the liquid guiding layer 5 A is of a vertically long shape, but does not overlap the pressing portion 90 a, the right pressing portion 9 0 b, the front pressing portion 9 0 c and the rear portion 90d, and the front extension is pressed. It is preferable that the portions 90e and 90f are not overlapped with the inner pressing portions 90g and 90h, and are located away from the respective portions. Therefore, each of the above-mentioned pressing portions can be formed in an equal state, and the entire sanitary napkin 1B can be easily attached to the body. In particular, when the liquid guiding layer 5A is disposed so as not to overlap the inner portions 90g and 9 Oh, the inner pressing portion and the 90h can be uniformly pressed, and the inner pressing can be easily performed. Starting from 90 g and 90 h, the front field of the center of the absorption field 1 1 B is bent. Further, the liquid guiding layer 5A may be formed so as not to overlap the pressing portions 90g and 9 Oh. For example, when the material of the liquid guiding layer 5 A having a large thickness and a high stiffness is formed, the liquid guiding layer 5 A is compressed by the inner pressing portions 90g and 90h, so that the guiding layer 5 having the length can be easily formed. The central absorption region 1 1 B of A is bent as described above with the above-mentioned inner pressing portion and 9 Oh as a starting point. Further, in the embodiment of Fig. 8, the front extension pressing portion 90e and the inner pressing portions 90g and 90h are not particularly provided. Further, the sanitary napkins 1, 1 A, and 1 B of the above-described embodiments have no side flaps at both side edges, but the sanitary napkins described above may be formed from the side edges toward the side surfaces. The right side of the convex buttocks will be pressed against the compression side pressure by 90g, and the inner side, hard liquid 9〇g. 90f, all form flank -37 - (34) 1263489. In the ninth embodiment, the structure of the sanitary napkin 1 shown in Figs. 1 and 2 is shown as an example, and the fourth embodiment in which the side flap portion is formed is shown. The sanitary napkin 1C shown in Fig. 9 is provided with a pair of side flap portions 2i, 2i extending from both side portions from the substantially central portion of the both side edges. In the sanitary napkin 1 C, the edge portions of the back sheet 2 have the same shape as the side flap portions 21 and 21, but the right edge portion 6 A and the left edge portion 6B of the surface sheet 6 extend only. To the base of the side flaps 2 1 , 2丨. On the left and right sides, the liquid-impermeable sheets 22, 22 formed of a hydrophobic non-woven fabric or a water-repellent non-woven fabric are superposed on the outermost surface. The inner edge portions 2 2 a, 2 2 a ' of the inner sides of the sheets 2 2, 2 2 are spaced apart from each other by a distance from the longitudinal center line 〇 y - 〇 y, and are laterally rounded from the above-mentioned pressing portion 9 At the position where the line 9B is separated, the surface sheet 6 is exposed in the area sandwiched by the edge portions 2 2 a and 2 2 a. The sheets 2 2, 2 2 are attached to the surface sheet 6 on both sides, and the side flaps 2 1 and 2 1 are followed by the back sheet 2. That is, the side flap portions 2 1 and 2 1 are the back sheet 2 and the sheet 22 are received by the liquid, and the liquid is impermeable to the portion. In the sanitary napkin 1C, the outer side of the auxiliary absorption field 12 is provided with the liquid-impermeable sheets 22 and 22, so that side leakage of menstrual blood or the like can be prevented. Further, the medicinal sanitary napkin 1 C can be reliably fixed to the lower portion of the crotch by sandwiching the side flap portions 2 1 and 2 1 with the adhesive layer and then covering the outer surface of the lower portion of the undergarment. >38-1263489 (35) Since the menstrual blood is not easily diffused from the central absorption region 1 1 having the liquid guiding layer 5 toward the surrounding portion, the sheet 2, 2 2 can be used as the lower water repellency. Moreover, it is not necessary to make the side flap portions 2 1 and 2 1 highly water-repellent. Further, as the above-mentioned sheets 2 2, 2 2, the basis weight can be used. Similarly, even if the side flap portions 2 1 and 2 are made to have a smaller basis weight, there is no fear of side leakage. Fig. 1 is a plan view showing a sanitary napkin 1 D of an absorbent article according to a fifth embodiment of the present invention. The sanitary tampon 1 D has a pattern shape of the pressing portion 190 which is different from each of the above embodiments, but the basic structure of the other sanitary tampon is the first embodiment shown in Fig. 2 Essentially the same. The pressing portion 190 includes a right pressing portion 9a and a left pressing portion 9b having substantially the same pattern shape as the pressing portion 9 shown in Fig. 2, and a front pressing portion 9c and a rear pressing portion 9d. The equal pressure portions 9a, 9b, 9c, and 9d are continuous in such a manner as to surround the central absorption region 1 1 , and the liquid guiding layer 5 is provided in the central absorption region 11 . The pressing portion 1 90 is formed with the pressing portion 9e extending from the boundary between the right pressing portion 9a and the front pressing portion 9c and extending forward, and similarly, the pressing portion 9b and the front portion are formed from the left side. The crimping portion 9f is extended before the boundary between the crimping portions 9c extends further forward. The front extension pressing portion 9e is located on the extension line of the right pressing portion 9a, and the front extension pressing portion 9f is also located on the extension line of the left pressing portion 9b. However, the front extension portion 9e. And the front extension pressing portion 9f is inclined so as to be closer to the longitudinal center line Oy-Oy toward the front edge portion 1C of the sanitary napkin, and the front side -39 - 1263489 (36) extends the pressing portion 9 e The terminal that extends before the pressing portion 9f is located away from the edge portion 1C, the right edge portion 1A, and the left edge portion 1B. Further, in the rear region, the pressing portion 9g is extended from the boundary between the right pressing portion 9a and the rear pressing portion 9d, and the pressing portion 9g is extended from the left pressing portion 9b and the rear pressing portion 9d. The junction is extended further rearward to extend the pressing portion 9H. The rear extension pressing portion 9g is located on the extension line of the right side pressing portion 9a, and the rear extension pressing portion 9 is located on the extension line of the left side pressing portion 9b. In the rear, the squeezing portion 9g and the rear squeezing portion 9H are inclined so as to be inclined toward the center line 〇y-〇y in the longitudinal direction toward the rear edge portion D of the sanitary napkin. The end portion of the pressing portion 9g and the rear extending pressing portion 9H is located away from the rear edge portion 1 D and the right edge portion 1 A and the left edge portion 1 B. Next, the sanitary napkin 1E of the sixth embodiment of the present invention, which is shown in plan view in Fig. 1, has the same structure as the sanitary napkin 1 C shown in Fig. 9 of the sanitary napkin 1E. The structure is provided with the side flap portions 2 1 and 2 1 extending from the left and right side portions, and is provided with the sheets 22 and 22° to sandwich the edge portions 22a and 22a of the two sheets 22 and 22, and is formed with The pressing portion 190 of the same pattern as the sanitary napkin 1D shown in Fig. 1 is shown. The sanitary napkins 1 D and 1 E are provided with a central absorption area 1 1 surrounded by a right pressing portion 9a, a left pressing portion 9b, a front pressing portion 9c, and a rear pressing portion 9d. In the field of the liquid guiding layer 5, -40-(37) 1263489 is deformed convexly toward the wearer side as shown in Fig. 5, and the central absorbent field 11 is easily attached to the excretion portion of the body. Further, in the field further forward than the front pressing portion 9c, the front extension pressing portion 9e and the front extension pressing portion 9f are formed to face each other as they are apart from each other toward the front edge portion 1C. Therefore, the area where the front pressing portion 9e and the right side edge portion 1A are sandwiched, and the region where the front extension pressing portion 9f and the left side edge portion 1B are sandwiched, it is easy to extend the pressing portion 9e and the front side forward. The extension crimping portion 9f is deformed toward the body direction as a bending starting point. Therefore, the sanitary tampon is easily attached to the front part of the femoral condyle of the body, similarly to the rear field, and is clamped to the field by the rear extension pressing portion 9g and the right side edge portion 1 A, and the pressing portion 9H is extended by the rear side. In the field sandwiched by the left side edge portion 1 B, it is also easy to deform the rearward pressing portion 9 9 and the rear extension pressing portion 9H as bending starting points in the body direction. Therefore, the sanitary napkin is easily deformed in conformity with the shape of the buttocks of the body. Further, since the liquid guiding layer 5 does not overlap the pressing portion 190, it is easy to form the pressing portion 190 in the equal compression state. In each of the embodiments shown in Fig. 1, Fig. 2, Fig. 7, Fig. 8, and Fig. 1 , by providing the liquid guiding layer 5, menstrual blood is less likely to diffuse outside the central absorption field 1 1 . In the surrounding area, the liquid permeable surface sheet forms a substantially entire area of the surface on the skin side, even if the liquid-impermeable sheet 22, 22 or the side flap portions 2 1 and 2 shown in Fig. 9 or Fig. 1 are not provided. 1 It is also easy to prevent menstrual blood from leaking toward the left and right sides. Further, as in the first embodiment, as shown in the first, fourth, seventh, ninth, tenth, and eleventh embodiments, even if it is particularly as shown in FIG. It is also not easy to prevent menstrual blood from leaking toward the buttocks as shown in the rear part. Further, as shown in Fig. 2(A)(B), the sanitary napkin according to the embodiment of the present invention can be formed on the left and right sides of the skin side surface of the sanitary napkin to extend in the longitudinal direction. The structure of the leakage preventing wall 5 0, 5 Ο A. The leakage preventing walls 50, 50A are formed by the liquid-impermeable sheet 22, and the sheet 22 is folded into two sheets, and is formed by sandwiching an elastic member 51 extending in the longitudinal direction on the inner side. Fig. 1 (2) and (B) show the state in which the sanitary napkin is cut at the lateral direction reference line Ox, but the sheet 22 which is folded into two sheets is stretched in the longitudinal direction of the sanitary napkin. The both end portions are integrally folded and then fixed to the surface sheet 6. Further, the elastic member 51 is fixed to the sheet 22 in a state where the longitudinal direction is elongated to a predetermined degree of stretch. The sanitary napkin has a curved shape by the contraction force of the elastic member 51, and as a result, the sheet 22 rises in a predetermined range before and after the lateral direction reference line Ox, and the leakage preventing walls 50, 50A are formed. By providing the leakage preventing wall 50, 50 A, it is possible to prevent the side leakage of the liquid, and by bending the physiological sanitary napkin as described above, it is easy to fit on the strand portion and form the leakage preventing wall 50. The sheet 22 of 50A, as shown in Fig. 12(A), can also stand up from the surface sheet 6, as shown in Fig. 2(B), -42-(39) 1263489 can also be simultaneously with the surface sheet 6. It is provided so as to be caught between the lower absorbent body 3 and the back sheet 2. Next, Fig. 13 is a view showing an example of a method of manufacturing the sanitary napkin 1 of the present invention. In the roll 100, the roll is used to form a non-woven fabric 1 such as a gas flow non-woven fabric of the liquid guiding layer 5. The non-woven fabric 101 is supplied to the heating unit 110 by the first driving roller 1 〇 2 . The heating unit 104 is provided with a hot air device 104, and hot air 105 is blown from the hot air port (not shown) of the hot air device 104 against the nonwoven fabric 101. By the blowing of the hot air 1 0 5 , the non-woven fabric 1 〇 1 restores the bulkiness. The above bulkiness is restored to 1 . 5 to 3 times the range, and the density is restored to 〇. 〇〇5g/ cm3~0. 02g/ cm3. The temperature of the hot air 1 〇 5 blown from the hot air device 104 is preferably a softening temperature of the material having the lowest softening temperature in the material constituting the air flow non-woven fabric, and is preferably a temperature higher than the softening temperature of the material having the highest softening temperature. Heating is more desirable. Specifically, the above heating temperature is 130 t to 300. (In the range of: the thickness-recoverable non-woven fabric 101 is supplied to the cooling device 1 〇7 while passing through the front or rear stage of the second drive roller 106, or passing therethrough. The above-described cooling device 107 is a discharge port When the air is blown out, the non-woven fabric 101 is rapidly cooled by being blown by the air. Further, the above-mentioned cooling device 1〇7 may be provided in a pair on the opposite sides of the surface of the non-woven fabric 1 0 1 . When the non-woven fabric 1 〇1 which is heated to recover the bulkiness is fixed in a short time, the nonwoven fabric 10 1 can be immediately maintained in a state in which the bulkiness of the nonwoven fabric is restored. After -43» (40) 1263489, even if the tension is applied to the above-mentioned non-woven fabric 1 489], the non-woven fabric 1 0 1 will not be crushed, and the bulkiness can be restored immediately after the tension is released. In particular, when the above-mentioned nonwoven fabric 101 is a nonwoven fabric formed of a thermoplastic fiber, the material constituting the nonwoven fabric is cooled to a softening temperature or lower. Therefore, even if the tension is applied, the nonwoven fabric can be prevented from being woven. i 〇1 The degree of bulkiness is lowered by the elongation. In the case of the conveying device not shown in Fig. 3, the rotation speed of the first driving roller 102 provided in the preceding stage of the heating unit 103 is set to the heating unit. It is preferable that the second driving light cylinder 1 〇6 has the same or faster rotation speed than the first stage. The non-woven fabric 1 0 1 ' passing through the heating unit 1 〇 3 is oriented toward the conveying direction due to the increase in bulkiness. The length is contracted, so if the rotation speed of the second drive roller 10 6 in the rear stage of the heating unit 10 3 is set to be faster than the rotation speed of the first drive roller 1 0 2 in the front stage of the heating unit 10 3 When the non-woven fabric is fast, even if the bulkiness is temporarily restored by the heating unit 103, the tension from the second driving roller 1 0 6 is received, and the elongation is again extended toward the contracted conveying direction to lower the bulkiness. Therefore, the length of the non-woven fabric 10 1 can be set by setting the rotation speed of the second driving roller 106 to be the same as or slower than the first driving roller 1 2 2 . No tension is applied in the direction to maintain a high loft state. However, it is more preferable that the apparatus 1 0 7 is provided in the front stage of the second driving roller 1 〇 6 to which the nonwoven fabric 1 供给 1 is supplied, so that the state of recovery of the nonwoven fabric 10 1 can be more easily maintained. The above-mentioned non-woven fabric 110 which is restored to the bulkiness is folded into a state in which, for example, the three sheets are overlapped as shown in Fig. 3 - 44 - 1263489 (41), and is supplied between the cutter rolls 1 Ο 8, 1 〇 9 The liquid guiding layer 5 is formed by being trimmed into a predetermined shape. The liquid guiding layer 5 is sucked by the conveying belt and sent to the rolls 1 1 3 and 11 4 . The cloth roll 1 1 is used to form a nonwoven fabric 1 1 1 such as a air flow non-woven fabric of the surface sheet 6. After the non-woven fabric 11 is passed through the roll 1 1 2, the nonwoven fabric 11 and the liquid guiding layer 5 are sandwiched between the rolls 1 1 3 and 1 1 4 and are superposed on each other to be supplied to the liquid-permeable hole forming roll. Between the cylinders i5 and 丨丨6, the above-mentioned liquid-permeable hole forming roller is provided with a plurality of needles for heating on the surface of the roller 1 115 which is opposite to the non-woven fabric η1 on which the surface sheet 6 is formed, and On the one hand, the surface of the roller 1 16 on the side opposite to the liquid guiding layer 5 is a smooth surface. When the non-woven fabric 11 1 and the liquid guiding layer 5 are supplied between the liquid-permeable forming rolls 1 1 5 and 1 16 , the heated needle penetrates the non-woven fabric 1 1 1 from the non-woven fabric 1 1 1 to The liquid guiding layer 5 is formed with a plurality of liquid permeable holes 15 . Since the non-woven fabric 11 1 and the liquid guiding layer 5 are coated with thermoplastic fibers, the thermoplastic fibers are fused by the penetration of the heating needle, and the nonwoven fabric 1 1 and the liquid are not woven in one of the liquid permeable holes 15 The guiding layers 5 will follow each other. Therefore, it is not necessary to apply an adhesive to the interface between the nonwoven fabric and the liquid guiding layer 5, but the non-woven fabric is formed; [1 and the liquid guiding layer 5 are formed by the liquid-permeable holes before the rolls 1 1 5 and 1 16 are formed. It is also possible to set the subsequent process of the non-woven fabric 11 1 and the liquid guiding layer 5 to the surface of the pulp lamination cylinder 120 to form a pulp layer of the upper layer absorber 4 and the lower-45-(42) 1263489 layer absorber 3. The body is patterned and held. The pulp layered body 121 supplied from the pulp layered cylinder 120 is placed on the fiber paper 1 2 5 drawn from the cloth roll 123' and then sandwiched from the fiber paper 1 2 5 and the cloth roll 1 2 2 Between the drawn paper sheets 1 2 4 and the pulp layered body 121 sandwiched by the fiber papers 124 and 125, the nozzles 126 are coated with heat applied in a wave pattern or a spiral pattern. Fused adhesive. The hot-melt adhesive is applied to the outer surface of the fiber paper 1 2 5 covering the pulp constituting the upper absorbent body 4. The pulp layered body 121, the nonwoven fabric ill, and the liquid guiding layer 5 are superposed and supplied between the light cylinders 1 2 7 and 1 2 8 , and the liquid guiding layer 5 and the pulp layer are covered by the hot-melt type adhesive. The fiber paper 125 on the surface of the body 2 1 is next. Further, a laminate formed of the paper-reinforced laminated body 1 2 1 surrounded by the nonwoven fabric 111, the liquid guiding layer 5, and the fiber papers 1 2 4 and 1 2 5 is supplied to the embossing cylinder 1 29, 1 30, the pressing portion 9 formed in FIG. 1 is formed, and the process of forming the pressing portion 9 is to form a smooth roll on the outer surface of the fiber paper 1 2 4 covering the pulp layered body 1 2 The cartridge 2, 9 is heated on the outer surface of the non-woven fabric 1 1 1 with a heat roller having a convex portion having an embossed pattern, and the paper purple laminated body 1 2 1 and the non-woven fabric 1 π are locally pressurized and heated. Further, a hot-melt type adhesive is applied to the outer surface of the fiber paper 1 2 4 of the laminated body by the nozzle 13 1 . When the non-hygroscopic film 1 3 3 forming the back sheet 2 is pulled out from the cloth roll 1 32, the thin g Wu 13 3 and the above laminated body may be between the rolls n 4 and 丨 3 5 - 46 - 1263489 ( 43) After being pressurized, a laminate having a film 1 3 3 superposed on the skin side surface is formed. The laminated body is supplied between the cutter rolls 136 and 137, and the sanitary napkin 1 having the shape shown in Fig. 1 is trimmed. Fig. 14 to Fig. 16 are another example of the above heating unit 100. In Fig. 14, the nonwoven fabric 1〇1 is supplied into the heating device 140. Hot air 141 is blown into the heating device 140, and the inside of the heating device 140 is completely heated. Therefore, both sides of the surface of the non-woven fabric 10 in the heating device 1404 are heated, and the bulkiness of the nonwoven fabric 1 〇 1 can be effectively restored. The heating unit 103 of Fig. 15 is composed of heating rolls 142 and 143. The nonwoven fabric 101 is heated by being wound around the heating rolls 142 and 143. The heating rolls 1 4 2 and 1 4 3 are separated from each other and the surface is smooth. The above-mentioned non-woven fabric 1 0 1 is not pressurized between the two heating rolls 1 4 2, 1 4 3, and is carried by the heating rolls 1 4 2 and 1 4 3, respectively. At this time, since one surface of the nonwoven fabric 101 is in contact with the surface of the heating roller 142 and heated, and the other surface of the nonwoven fabric 101 is in contact with the surface of the heating roller 143 and heated, the nonwoven fabric 101 is provided by two The heating rolls 1 4 2 , : I 4 3 are heated on both sides. In the middle of the drawing, a rotating cylinder 145 is disposed between the brother 1 driving light cylinder 1 〇 2 and the second driving light cylinder 106. The outer peripheral surface of the rotary cylinder 145 is separated by a predetermined distance, and a hot air blower 146 is provided along the outer peripheral surface of the rotary cylinder 145. The hot air device touches the non-woven fabric 1 when the film 101 passes over the rotary cylinder 135 at a predetermined interval between the hot air package-4 / - 1263489 (44) and the rotary cylinder 1 4 5 . 1. When the non-woven fabric 101 passes over the rotary cylinder 145, the hot air blow port (not shown) of the air device 146 faces the above-mentioned non-wet hot air 147, and the bulkiness of the non-woven fabric 1 〇1 is the Huo De cylinder 1 4 5 itself. If there is heating, it is possible to heat the above-mentioned non-woven fabric surface to effectively restore the bulkiness, which is more desirable. Further, the relationship between the first drive roller 102 and the second drive roller speed, or the description of the cooling device 107 is the same as that of the first embodiment, and therefore will not be described. Further, in the heating unit 103 and the cooling device 1〇7 described above, the conveyance process of the non-woven fabric 1 1 1 of the sheet 6 is also provided, and the woven fabric 1 1 1 and the non-woven fabric 1 0 1 are simultaneously restored to the bulkiness. Further, the non-woven fabric 11 1 and the liquid guiding layer may be heated and cooled together with the liquid guiding layer 5 (Examples) (Example A) Hereinafter, the absorbent of the present invention will be described by comparison with comparative examples.

(1 1 ) The thicknesses of the airflow non-woven fabrics of the above examples and comparative examples were measured. The airflow non-woven fabrics of the above examples and comparative examples were made into a scale of 10 0 X 10 . For samples of 0mm size, use 2 pieces of 100x200mm acrylic plates with a mass of 70g, and take the above samples as two pieces. The crepe plate was clamped. The thickness of each sample was measured using a thickness gauge of U F-60A model manufactured by Daiei Scientific Seiko Co., Ltd. under the condition of sandwiching each sample on the acrylic plate. The thickness is measured. The thickness measurement is performed after the terminal of the thickness gauge is placed on the acrylic plate for 1 minute. The following is the same. Secondly, the samples are completely immersed in the artificial menstrual blood described in the embodiment A. Immediately, afterwards, each sample was clamped with the above-mentioned acrylic plate, and the thickness of the sample was measured using the above thickness gauge as the thickness at the time of wetting. Next, each sample was completely immersed in artificial menstrual blood. After being lifted up in an instant and clamped to the above acrylic plate, a weight of 930 g is applied to the terminal of the thickness gauge, and a pressure of 980 Pa (10 g/cm 2 ) is applied to the acrylic plate. The terminal is placed on the acrylic sheet for 1 minute to measure the thickness of the sample. This is used as the thickness in the wet state and under pressure. Next, the weight is removed to restore the thickness of the liquid guiding layer of each sample, after 1 minute. Then measure the thickness in the same way.

As a surface sheet for testing, a polyethylene terephthalate (PET) having a core portion of 1.1% by mass of a fiber and a polyethylene (PE) portion having a sheath portion was used. The core-sheath composite synthetic fiber of the core form has a fineness of 2.2 dtex, a fiber length of 44 mm, and a basis weight of 25 g / m 2 of a non-woven fabric. The above surface sheet is cut into a width of 1 0 0 m and a length of 2 0 0 m. As the absorption layer for measurement, a mixture of -56-1263489 (53) pulp having a basis weight of 160 g/m2 and a superabsorbent polymer of 8 g/m2 was used, and the size was 180 mm, and the width was 75 mm. The lower layer absorber, the chemical pulp layered body, and having a basis weight of 203 g/m2, a length of 120 mm, and a width of 55 mm below the layer absorber. The upper layer absorber was superposed on the lower layer, and the upper and lower sides were sandwiched by a basis weight of 15 g/m2. The above-mentioned absorbing layer and the above liquid guiding layer were superposed on a plate having a width of 100 mm and a length of 200 mm to form a surface sheet. In the center of the acrylic sheet having a mass of 115 g and a width of 100 mm, a length of 40 mm is formed in the center portion of the acrylic sheet having a length of 200 mm, and a length of 40 mm in the longitudinal direction is formed on the surface sheet. And set the above long hole in the center of the sample. The artificial menstrual blood is injected from the elongated hole. Injection rate; i / mi η, supplied 3 m 1 at the first time, after the liquid is removed from the surface of the sample by $1, at the same injection rate, 4 m at the second injection, after the liquid disappears for 30 seconds, at the third time. After the injection of 3 m at the same injection speed and the third injection, it was confirmed that the liquid was removed from the surface of the sample, and then the acrylic plate having the elongated holes was removed, and the size of the liquid sheet to be diffused in the lateral direction was measured. The diffusion size is the longest distance between the long direction and the lateral direction.

Therefore, since the state in which the three non-woven fabrics are overlapped is measured, the thickness of the liquid guiding layer in the wet state is 1.5 to 3 mm - 58 to 1263489 (55), and the above-mentioned restored thickness is 3 to 6 mm. Further, in the case of drying, the density at the time of drying is 0.005 to 0.02 g / cm3, and the density at the time of wetting and pressurization is O.OOSg / cm3 to O.CMg / cm3. [Effects of the Invention] As described above, according to the present invention, it is possible to quickly inhale a liquid which is repeatedly received in a limited range in the central portion of the absorbent article, thereby preventing the liquid from diffusing on the surface sheet, and even if the liquid moves toward the side, It is quickly absorbed and can effectively prevent side leakage. In particular, in the present invention, the central portion is a structure which can be closely followed by the body excretion portion, and has a good touch to the body and is capable of absorbing liquid in the central portion.
