吸收性物品 Absorbent article

本發明關於一種吸收性物品。 The present invention relates to an absorbent article.

吸收性物品，例如生理用衛生棉、護墊等，經由長年累積的技術開發，已漸漸地提升基本性能，與以往相比，吸收經血等***物之後，外漏等較少發生，目前更進一步追求高機能化，例如具有貼近肌膚的著用感。 Absorbent articles, such as sanitary napkins and pads, have been gradually developed to improve basic performance through years of accumulated technology. Compared with the past, absorption of excretions such as menstrual blood, leakage, etc. occur less frequently. The pursuit of high performance, for example, has a sense of closeness to the skin.

且，例如引證1中記載一種吸收性物品，其係在頂部薄片之外表面中的至少一部分包含有效量的乳液塗覆，該乳液塗覆在20℃下為半固體或固體，且能夠部分地移動到著用者的肌膚。且，上述乳液塗覆中包含：10~95%之(i)在20℃下具有可塑性或流動一致性，並包含選自石油基底之柔軟劑、脂肪酸酯柔軟劑、烷基乙氧基化柔軟劑、以及此等之混合物中的1種，且實質上不包含水分之柔軟劑、與5~90%之(ii)能夠將柔軟劑固定在頂部薄片的外表面上之固定化物質，且前述固定化物質具有至少35℃，較佳為至少40℃之融點，並選自多元羥基脂肪酸酯、多元羥基脂肪酸醯胺、C_14-C₂₂脂肪醇、C_12-C₂₂脂肪 酸、C_12-C₂₂脂肪醇乙氧基化物、以及此等之混合物。 Also, for example, reference is made to an absorbent article comprising at least a portion of the outer surface of the top sheet comprising an effective amount of an emulsion coating which is semi-solid or solid at 20 ° C and capable of being partially Move to the user's skin.

引證1中，具有35℃以上之融點的固定化物質由於在乳液塗覆中於室溫(25℃)下會結晶化，乳液塗覆的黏度會升高，具有使乳液塗覆不動化之作用。 In Citation 1, an immobilized material having a melting point of 35 ° C or higher is crystallized at room temperature (25 ° C) in emulsion coating, and the viscosity of the emulsion coating is increased, and the emulsion coating is immobilized. effect.

然而，使用固定化物質使乳液塗覆不動化(高黏度化)的話，本身就存在著有效成分之「柔軟劑」會難以從乳液塗覆中釋出的問題點。且，即使將乳液塗覆不動化(高黏度化)，在體壓等高壓力之下，乳液塗覆會移動至吸收性物品的內部(頂部薄片之纖維的空隙等)，會有「柔軟劑」難以持續對著用者的肌膚產生作用之問題點。 However, when the immobilized material is used to imprint the emulsion (high viscosity), there is a problem that the "softener" of the active ingredient is difficult to release from the emulsion coating. Moreover, even if the emulsion is coated immovable (high viscosity), under the high pressure such as body pressure, the emulsion coating moves to the inside of the absorbent article (the void of the fibers of the top sheet, etc.), and there is a "softener". It is difficult to continue to have problems with the user's skin.

因此，本發明之目的為提供一種將保護著用者肌膚的乳液連續地釋放至著用者肌膚之吸收性物品。 Accordingly, an object of the present invention is to provide an absorbent article which continuously releases an emulsion for protecting a user's skin to the skin of a user.

針對本發明之吸收性物品，以下進行詳細的說明。 The absorbent article of the present invention will be described in detail below.

本發明之吸收性物品具備液體透過性層、與液體不透過性層、與上述液體透過性層以及液體不透過性層之間的吸收層。 The absorbent article of the present invention comprises a liquid permeable layer, an opaque layer, and an absorbing layer between the liquid permeable layer and the liquid permeable layer.

[膠體乳液] [colloidal emulsion]

本發明之吸收性物品中，膠體乳液包含膠體化劑與乳液。 In the absorbent article of the present invention, the colloidal emulsion contains a colloidizing agent and an emulsion.

膠體化劑係為了保持上述乳液之成分，包含苯乙烯系彈性體。 The colloidalizing agent contains a styrene-based elastomer in order to retain the components of the above emulsion.

作為上述苯乙烯系彈性體，具有硬段以及軟段者較佳，且作為上述硬段，以聚苯乙烯嵌段較佳，且作為上述軟段，以聚烯烴嵌段較佳。 The styrene-based elastomer preferably has a hard segment and a soft segment, and is preferably a polystyrene block as the hard segment, and a polyolefin block as the soft segment.

上述聚苯乙烯嵌段中不僅包含苯乙烯之同元共聚物而成的嵌段(亦即聚苯乙烯嵌段)，亦包含α-甲基苯乙烯之同元共聚物而成的嵌段(亦即聚α-甲基苯乙烯嵌段)、以及苯乙烯與α-甲基苯乙烯之共聚合物而成的嵌段。 The above polystyrene block includes not only a block of a homopolymer of styrene (that is, a polystyrene block) but also a block of a homopolymer of α-methylstyrene ( That is, a block of a poly-α-methylstyrene block and a copolymer of styrene and α-methylstyrene.

作為上述聚烯烴嵌段，有舉例如聚烯烴之同元共聚物而成之嵌段，例如聚乙烯嵌段、聚丙烯嵌段、聚丁烯嵌段、以及聚丁二烯嵌段、以及聚烯烴之共聚合物而成之嵌段、例如乙烯、丙烯、丁烯以及丁二烯等之共聚合物而成之嵌段。 As the above polyolefin block, there may be mentioned, for example, a block of a homopolymer of polyolefin, such as a polyethylene block, a polypropylene block, a polybutene block, and a polybutadiene block, and a poly A block formed of a copolymer of an olefin, for example, a copolymer of ethylene, propylene, butylene, and butadiene.

且，本說明書中，在方便上，丁二烯也作為正烯系單體使用。 Further, in the present specification, butadiene is also used as a normal olefin monomer.

且，上述軟段中亦包含聚丁二烯嵌段之氫加成物、以及丁二烯與乙烯、丙烯、丁烯及丁二烯等之共聚合物而成的嵌段之氫加成物。 Further, the soft segment further comprises a hydrogen adduct of a polybutadiene block and a hydrogen adduct of a block of butadiene and a copolymer of ethylene, propylene, butylene and butadiene. .

作為上述苯乙烯系彈性體，以在兩末端具有硬段，並在此等之間具有1種或複數種軟段較佳。 The styrene-based elastomer preferably has a hard segment at both ends, and one or a plurality of soft segments are preferably provided between the two.

作為上述苯乙烯系彈性體之具體例，有舉例如以下。 Specific examples of the styrene-based elastomer are as follows.

(i)聚苯乙烯-block-聚(乙烯-co-丙烯) (i) polystyrene-block-poly(ethylene-co-propylene)

(以下，有時省略成「SEP」) (The following may be omitted as "SEP")

(ii)聚苯乙烯-block-聚(乙烯-co-丙烯)-block-聚苯乙烯 (ii) polystyrene-block-poly(ethylene-co-propylene)-block-polystyrene

(以下，有時省略成「SEPS」) (The following may be omitted as "SEPS")

(iii)聚苯乙烯-block-聚(乙烯-co-丁烯)-block-聚苯乙烯 (iii) polystyrene-block-poly(ethylene-co-butylene)-block-polystyrene

(以下，有時省略成「SEBS」) (The following may be omitted as "SEBS")

(iv)聚苯乙烯-block-聚乙烯-block-聚(乙烯-co-丙烯)-block-聚苯乙烯 (iv) polystyrene-block-polyethylene-block-poly(ethylene-co-propylene)-block-polystyrene

(以下，有時省略成「SEEPS」) (The following may be omitted as "SEEPS")

上述苯乙烯系彈性體較佳為具有5,000~500,000，再較佳為具有10,000~400,000，且更較佳為具有50,000~300,000之重量平均分子量。若上述重量平均分子量低於5,000，則苯乙烯系彈性體會有難以保持在膠體構造之傾向，且若上述重量平均分子量超過500,000，則所形成之膠體的50%變形時的壓縮應力會變高，著用感會有降低之傾向。 The styrene-based elastomer preferably has a weight average molecular weight of 5,000 to 500,000, more preferably 10,000 to 400,000, and still more preferably 50,000 to 300,000. When the weight average molecular weight is less than 5,000, the styrene-based elastomer tends to be difficult to maintain in the colloidal structure, and if the weight average molecular weight exceeds 500,000, the compressive stress at 50% deformation of the formed colloid becomes high. There is a tendency to reduce the sense of use.

且，重量平均分子量之測定方法如後述。 Further, the method for measuring the weight average molecular weight will be described later.

上述苯乙烯系彈性體較佳為包含10~50質量%之聚苯乙烯嵌段與50~90質量%之聚烯烴嵌段，再較佳為包含15~40質量%之聚苯乙烯嵌段與60~85質量%之聚烯 烴嵌段，且更較佳為包含18~35質量%之聚苯乙烯嵌段與65~82質量%之聚烯烴嵌段。 The styrene-based elastomer preferably contains 10 to 50% by mass of a polystyrene block and 50 to 90% by mass of a polyolefin block, and more preferably 15 to 40% by mass of a polystyrene block. 60 to 85% by mass of polyolefin The hydrocarbon block, and more preferably contains 18 to 35% by mass of a polystyrene block and 65 to 82% by mass of a polyolefin block.

若聚苯乙烯嵌段的量低於10質量%，則會有聚苯乙烯嵌段難以形成後述微米層分離構造之傾向。若聚苯乙烯嵌段的量超過50質量%，則能夠保持乳液之聚烯烴嵌段的量變少，故能夠保持之乳液的量會有變少之傾向。且，聚苯乙烯嵌段之微米層分離構造的量變多，所形成的膠體乳液會凝固，會有著用感變差之傾向。 When the amount of the polystyrene block is less than 10% by mass, the polystyrene block tends to be difficult to form a micron-separated structure described later. When the amount of the polystyrene block exceeds 50% by mass, the amount of the polyolefin block capable of holding the emulsion is reduced, so that the amount of the emulsion that can be held tends to be small. Further, the amount of the micron layer separation structure of the polystyrene block is increased, and the formed colloidal emulsion is solidified, which tends to deteriorate the feeling of use.

上述苯乙烯系彈性體會生成膠體乳液之理由如以下所述。苯乙烯系彈性體之硬段會互相凝集形成一範圍，並有作為交聯點之作用。另一方面，軟段會發揮連結此等交聯點之網孔的角色。其結果，苯乙烯系彈性體具有作為彈性體之機能。 The reason why the above styrene-based elastomer forms a colloidal emulsion is as follows. The hard segments of the styrene elastomer will agglomerate to each other to form a range and function as a crosslinking point. On the other hand, the soft segment will play the role of the mesh connecting these cross-linking points. As a result, the styrene-based elastomer has a function as an elastomer.

將上述苯乙烯系彈性體與上述乳液，尤其是與烴基混合後，苯乙烯系彈性體之軟段會保持上述乳液，另一方面，硬段會維持在形成一範圍之狀態。其結果，苯乙烯系彈性體與上述乳液之混合物(膠體乳液)具有下述彈性體之機能，該彈性體具有比苯乙烯系彈性體單體更低的壓縮應力。 When the styrene-based elastomer is mixed with the above emulsion, particularly with a hydrocarbon group, the soft segment of the styrene-based elastomer retains the emulsion, and on the other hand, the hard segment is maintained in a state of being formed. As a result, the mixture of the styrene-based elastomer and the above emulsion (colloidal emulsion) has the function of an elastomer having a lower compressive stress than the styrene-based elastomer monomer.

且，上述乳液僅會被保持在苯乙烯系彈性體之軟段中較鬆的網孔，並能夠移動到膠體乳液的表面。 Moreover, the above emulsion is only retained in the looser mesh in the soft section of the styrenic elastomer and can be moved to the surface of the colloidal emulsion.

上述乳液包含烴。本說明書中，「烴」意指碳與氫而成之化合物。作為上述烴，有舉出鏈狀烴，例如石臘系烴(不包含雙鍵以及三鍵，亦稱作烷)、正烯系烴(包 含1個雙鍵，亦稱作烯)、乙炔系烴(包含1個三鍵，亦稱作炔)、及包含2個以上選自雙鍵以及三鍵所成群中之鍵結的烴、以及環狀烴，例如芳香族烴、脂環式烴。 The above emulsion contains a hydrocarbon. In the present specification, "hydrocarbon" means a compound in which carbon and hydrogen are formed. Examples of the hydrocarbon include a chain hydrocarbon such as a paraffinic hydrocarbon (excluding a double bond and a triple bond, also referred to as an alkane), and a normal olefinic hydrocarbon (package). a double bond, also known as an alkene, an acetylene hydrocarbon (containing one triple bond, also referred to as an alkyne), and a hydrocarbon containing two or more bonds selected from the group consisting of a double bond and a triple bond, And cyclic hydrocarbons such as aromatic hydrocarbons and alicyclic hydrocarbons.

作為上述烴，為鏈狀烴以及脂環式烴較佳，為鏈狀烴再較佳，為石臘系烴、正烯系烴、及包含2個以上之雙鍵的烴(不包含三鍵)更較佳，且為石臘系烴更較佳。 The hydrocarbon is preferably a chain hydrocarbon or an alicyclic hydrocarbon, and more preferably a chain hydrocarbon, and is a paraffinic hydrocarbon, a normal olefinic hydrocarbon, and a hydrocarbon containing two or more double bonds (excluding a triple bond) More preferably, it is more preferred as a paraffinic hydrocarbon.

上述鏈狀烴中包含直鏈狀烴以及分支狀烴。 The chain hydrocarbons include linear hydrocarbons and branched hydrocarbons.

上述烴為在40℃中具有0.01~80mm²/s之動力黏度較佳，具有0.01~4.0質量%之抱水率較佳，且具有未滿1,000之重量平均分子量較佳。是因為烴可作為後述之體液滑性賦予劑來作用。 The above hydrocarbon has a dynamic viscosity of preferably 0.01 to 80 mm ² /s at 40 ° C, a water absorbing ratio of 0.01 to 4.0% by mass, and a weight average molecular weight of less than 1,000. This is because hydrocarbons can act as a body fluid slip imparting agent to be described later.

本發明之膠體乳液中，乳液(例如烴)會有一定量滲出到膠體乳液的表面。滲出到表面的乳液會移動到著用者的肌膚，或者會與經血、尿等體液一起滑落到吸收體內部等而消失，之後新的乳液會從膠體乳液再滲出。因此，膠體乳液能夠連續地釋放出乳液。 In the colloidal emulsion of the present invention, an emulsion (e.g., a hydrocarbon) will have a certain amount of exudation to the surface of the colloidal emulsion. The emulsion that has oozing out to the surface will move to the user's skin, or will disappear with the body fluid such as menstrual blood or urine, and disappear into the inside of the absorbent body, and then the new emulsion will re-bleed out from the colloidal emulsion. Therefore, the colloidal emulsion is capable of continuously releasing the emulsion.

上述乳液較佳為包含50~100質量%，再較佳為包含60~100質量%，且更較佳為包含70~100質量%之上述烴。這是以膠體形成之觀點來看。 The above emulsion preferably contains 50 to 100% by mass, more preferably 60 to 100% by mass, and still more preferably 70 to 100% by mass of the above hydrocarbon. This is in terms of colloid formation.

上述膠體乳液中，作為上述乳液，除了上述烴以外，亦能夠進一步包含該發明所屬技術領域中熟知用來作為乳液之成分。 In the above colloidal emulsion, as the above-mentioned emulsion, in addition to the above hydrocarbons, it is possible to further comprise a component which is well known as an emulsion in the technical field of the invention.

上述膠體乳液中，作為上述乳液，除了上述烴以外， 進一步包含體液滑性賦予劑較佳，該體液滑性賦予劑具有超過0.00且0.60以下之IOB、與40℃下為0.01~80mm²/s之動力黏度、與0.01~4.0質量%之抱水率、與未滿1,000之重量平均分子量。 In the above-mentioned colloidal emulsion, it is preferable to further include a body fluid slip imparting agent as the above-mentioned emulsion, and the body fluid slip imparting agent has an IOB of more than 0.00 and 0.60 or less, and 0.01 to 80 mm ² /s at 40 ° C. The dynamic viscosity, the water holding ratio of 0.01 to 4.0% by mass, and the weight average molecular weight of less than 1,000.

上述體液滑性賦予劑為本案申請人之申請案，與國際公開第2012/133724號說明書所記載之「血液改質劑」相同成分，且同樣地與國際公開第2013/129236號說明書所記載之「血液滑性賦予劑」為相同成分。 The above-mentioned body fluid slip imparting agent is the same as the "blood modifier" described in the specification of International Publication No. 2012/133724, and is similarly described in the specification of International Publication No. 2013/129236. The "slipperiness imparting agent" is the same component.

藉由上述膠體乳液中包含上述體液滑性賦予劑，體液滑性賦予劑會從膠體乳液連續地釋放出，經過長時間，能夠使到達液體透過性層之體液等迅速地滑落到吸收體的內部。 When the body fluid slip imparting agent is contained in the colloidal emulsion, the body fluid slip imparting agent is continuously released from the colloidal emulsion, and the body fluid or the like reaching the liquid permeable layer can be quickly slipped to the inside of the absorbent body over a long period of time. .

IOB(Inorganic Organic Balance)為表示親水性以及親油性之平衡的指標，本說明書中是意指根據小田等之下式：IOB=無機性值/有機性值所算出之值。 IOB (Inorganic Organic Balance) is an index indicating the balance between hydrophilicity and lipophilicity, and in the present specification, it means a value calculated according to the formula of Oda et al.: IOB=inorganic value/organicity value.

藤田氏之主要的基之有機性值以及無機性值統整於下述表1。 The main organic and inorganic values of Fujita's base are summarized in Table 1 below.

上述動力黏度是根據JIS K 2283：2000之「5.動力黏度試驗方法」，並使用Cannon-Fenske逆流形黏度計，在40℃之試驗溫度下測定。 The above dynamic viscosity is measured according to "5. Dynamic viscosity test method" of JIS K 2283:2000, and measured at a test temperature of 40 ° C using a Cannon-Fenske counter-flow viscosity meter.

上述膠體乳液會連續地釋放出體液滑性賦予劑至吸收性物品之肌膚接觸區域，例如，由於是緩緩釋放出，即使體液滑性賦予劑與體液一起滑落到吸收性物品內部，新的體液滑性賦予劑也會再從膠體乳液被供給至液體透過性層之表面，並使體液繼續滑落到吸收性物品內部。其結果，即使長時間連續使用吸收性物品時，液體透過性層也難以產生沾黏感，液體透過性層會繼續保持在乾爽狀態。 The above colloidal emulsion continuously releases the body fluid slip imparting agent to the skin contact area of the absorbent article, for example, because it is slowly released, even if the body fluid slip imparting agent slides down into the absorbent article together with the body fluid, the new body fluid The slip imparting agent is also supplied from the colloidal emulsion to the surface of the liquid permeable layer, and the body fluid continues to slide down into the interior of the absorbent article. As a result, even when the absorbent article is continuously used for a long period of time, the liquid permeable layer is less likely to have a sticky feeling, and the liquid permeable layer continues to be in a dry state.

上述乳液中較佳為包含0~50質量%，再較佳為包含0~40質量%，且更較佳為0~30質量%之上述體液滑性賦予劑。這是以膠體形成之觀點來看。 The above emulsion preferably contains 0 to 50% by mass, more preferably 0 to 40% by mass, and still more preferably 0 to 30% by mass of the above-mentioned body fluid slip imparting agent. This is in terms of colloid formation.

上述膠體乳液中基於此等之合計100質量份，較佳分別以1~30質量份以及70~99質量份，再較佳分別以2~20質量份以及80~98質量份，且更較佳分別以3~15質量份以及85~97質量份之比率包含膠體化劑與乳液。上述膠體化劑之比率若低於1質量份，則所形成之膠體乳液會難以具有彈性體之作用，或是當施加體壓時會有超過膠體乳液之彈性界限而變形的情況。上述膠體化劑之 比率若超過30質量份，則所形成之膠體乳液的彈性會變高，有時著用感會變差。 The above-mentioned colloidal emulsion is preferably used in an amount of from 1 to 30 parts by mass and from 70 to 99 parts by mass, more preferably from 2 to 20 parts by mass and from 80 to 98 parts by mass, and more preferably, based on 100 parts by mass of the total of the above-mentioned colloidal emulsions. The colloidizing agent and the emulsion are contained in a ratio of 3 to 15 parts by mass and 85 to 97 parts by mass, respectively. When the ratio of the above colloidizing agent is less than 1 part by mass, the formed colloidal emulsion may have difficulty in functioning as an elastomer or may be deformed when the body pressure is applied, which exceeds the elastic limit of the colloidal emulsion. The above colloidal agent When the ratio exceeds 30 parts by mass, the elasticity of the formed colloidal emulsion becomes high, and the feeling of use may be deteriorated.

上述膠體乳液具有1~100kPa之50%變形時的壓縮應力，較佳為具有1~80kPa之50%變形時的壓縮應力，再較佳為具有1.5~60kPa之50%變形時的壓縮應力。 The colloidal emulsion has a compressive stress at 50% deformation of 1 to 100 kPa, preferably a compressive stress at 50% deformation of 1 to 80 kPa, and more preferably a compressive stress at 50% deformation of 1.5 to 60 kPa.

50%變形時的壓縮應力若低於1kPa，則施加體壓時會有膠體乳液超過彈性界限而變形，並有被破壞的情況，且50%變形時的壓縮應力若超過100kPa，則膠體乳液之彈性會變高，施加體壓時膠體乳液會難以變形，著用者會有察覺到違和感之情況。 When the compressive stress at 50% deformation is less than 1 kPa, when the body pressure is applied, the colloidal emulsion is deformed beyond the elastic limit and is broken, and if the compressive stress at 50% deformation exceeds 100 kPa, the colloidal emulsion is The elasticity will become high, and the colloidal emulsion will be difficult to deform when the body pressure is applied, and the user will perceive the feeling of discomfort.

以往的乳液塗覆、護膚劑等，為了將有效成分固定在特定的地方，採用將此等高黏度化(黏性體化)之手法。然而，將此等高黏度化之後，有效成分(柔軟劑等)會被鎖在乳液塗覆、護膚劑等之內部，變得難以發揮其機能。且，以往的乳液塗覆、護膚劑等，只是黏性體，若施加著壓等體壓，會有無法固定於特定的地方，，移動到吸收性物品內部，難以持續對著用者之肌膚作用的問題點。 Conventional emulsion coatings, skin care agents, and the like, in order to fix an active ingredient in a specific place, a method of making such a high viscosity (viscosity) is employed. However, after such high viscosity, the active ingredient (softener, etc.) is locked inside the emulsion coating, the skin care agent, etc., and it becomes difficult to exert its function. In addition, conventional emulsion coatings, skin care agents, and the like are only viscous bodies. If a body pressure such as pressure is applied, they may not be fixed to a specific place, and may move to the inside of the absorbent article, and it is difficult to continue to face the user's skin. The problem point.

另一方面，上述膠體乳液會在有施加體壓等之範圍內表現作為彈性體之現象。因此，即使對上述膠體乳液施加較高的體壓，也會一直停留在彈性變形，且不會被擠壓至頂部薄片的纖維等之間，而在體壓變低之後，彈性會回復，並回到原本的位置(肌膚接觸區域)。因此，膠體乳液中所包含之乳液能夠在所期望的位置中達成其作用。 On the other hand, the above-mentioned colloidal emulsion exhibits a phenomenon as an elastomer in a range in which a body pressure or the like is applied. Therefore, even if a high body pressure is applied to the above-mentioned colloidal emulsion, it will remain elastically deformed and will not be squeezed between the fibers of the top sheet, etc., and after the body pressure becomes low, the elasticity will recover, and Return to the original position (skin contact area). Therefore, the emulsion contained in the colloidal emulsion can achieve its effect in the desired position.

The absorbent article 1 shown in Fig. 1, more specifically, the sanitary napkin has a top sheet 2 as a liquid permeable layer, a bottom sheet as a liquid impermeable layer (not shown), and a top portion. An absorbent body 3 serving as an absorbent layer between the sheet 2 and the bottom sheet (not shown). The absorbent article 1 shown in Fig. 1 also has a side sheet 4 and an embossing portion 5.

In other words, the top sheet 2 contains a plurality of linear colloidal emulsions 6 which are parallel to each other and extend in the longitudinal direction of the absorbent article 1.

圖2表示根據有別於本發明實施形態之吸收 性物品1的平面圖。圖2所表示之吸收性物品1，更具體來說為生理用衛生棉中，頂部薄片2在其肌膚接觸區域中包含膠體乳液6，且複數個點狀膠體乳液6被塗佈成千鳥狀。換而言之，頂部薄片2中包含被配置成千鳥狀的複數個點狀膠體乳液6。 Figure 2 shows absorption according to an embodiment different from the present invention. Plan view of the sexual item 1. In the absorbent article 1 shown in Fig. 2, more specifically, in a sanitary napkin, the top sheet 2 contains a colloidal emulsion 6 in its skin contact area, and a plurality of point-like colloidal emulsions 6 are coated in a thousand birds. In other words, the top sheet 2 contains a plurality of point-like colloidal emulsions 6 arranged in a thousand bird shape.

本發明之吸收性物品中，關於塗佈有上述膠體乳液之面積並無特別限制，但以不阻礙吸收性物品的通氣性之觀點來看，與著用者肌膚接觸的區域中，較佳為塗佈1~50%，再較佳為塗佈3~40%，且更較佳為塗佈5~30%之區域。 In the absorbent article of the present invention, the area in which the colloidal emulsion is applied is not particularly limited, but it is preferably in a region in contact with the user's skin from the viewpoint of not impeding the air permeability of the absorbent article. The coating is 1 to 50%, more preferably 3 to 40%, and more preferably 5 to 30%.

且，在液體透過性層中塗佈有上述膠體乳液之實施形態中，上述膠體乳液，在液體透過性層與吸收性層在吸收性物品的厚度方向上重複的範圍之內，被塗佈為液體透過性層面積之1~50%的區域較佳，被塗佈為液體透過性層面積之3~40%的區域再較佳，且被塗佈為液體透過性層面積之5~30%的區域更較佳。 In the embodiment in which the colloidal emulsion is applied to the liquid permeable layer, the colloidal emulsion is applied as a range in which the liquid permeable layer and the absorbent layer are repeated in the thickness direction of the absorbent article.

The area is better.

若上述膠體乳液塗佈未滿液體透過性層面積之1%，則會有難以發揮本發明效果之傾向。若上述膠體乳液塗佈超過液體透過性層面積之50%的區域時，由於塗佈有膠體乳液的區域不會吸收體液，作為其結果，吸收體液的區域會變窄，吸收性會有降低之傾向。 When the above-mentioned colloidal emulsion coating is less than 1% of the area of the liquid permeable layer, it is difficult to exhibit the effects of the present invention. When the colloidal emulsion is applied in a region exceeding 50% of the area of the liquid permeable layer, the body fluid is not absorbed in the region where the colloidal emulsion is applied, and as a result, the region in which the body fluid is absorbed is narrowed, and the absorbability is lowered. tendency.

且，為了達成上述塗佈區域，液體透過性層與吸收性層在吸收性物品厚度方向上重複的範圍之內，較佳為以1~30g/m²，再較佳為以2~20g/m²，且更較佳為以 3~10g/m²之基重包含上述膠體乳液。 Further, in order to achieve the coating region, the liquid permeable layer and the absorbent layer are preferably in the range of 1 to 30 g/m ² , more preferably 2 to 20 g / in the range in which the absorbent article is repeated in the thickness direction of the absorbent article. m ² , and more preferably contains the above colloidal emulsion at a basis weight of 3 to 10 g/m ² .

本說明書中，膠體乳液之基重如以下來測定。 In the present specification, the basis weight of the colloidal emulsion is measured as follows.

(1)將頂部薄片之應測定的範圍以銳利的刀具，例如刀片的替換刀片切出，得到樣品。 (1) The range to be measured of the top sheet is cut out with a sharp blade such as a replacement blade of the blade to obtain a sample.

(2)樣品之面積：測定A(m²)以及質量：M₀(g)。 (2) Area of sample: Determination of A (m ² ) and mass: M ₀ (g).

(3)將樣品在膠體乳液為可溶之溶媒，例如芳香族系溶媒，例如二甲苯等之中，至少攪拌3分鐘，使膠體乳液溶解於溶媒中。 (3) The sample is stirred at least for 3 minutes in a solvent in which the colloidal emulsion is soluble, for example, an aromatic solvent such as xylene, and the colloidal emulsion is dissolved in the solvent.

(4)將樣品在已測定質量的濾紙上進行過濾，在濾紙上，以溶媒將樣品充分洗淨。將濾紙上之樣品於100℃之烘箱內進行乾燥。 (4) The sample was filtered on the filter paper of the measured mass, and the sample was thoroughly washed with a solvent on the filter paper. The sample on the filter paper was dried in an oven at 100 °C.

(5)測定濾紙以及樣品之質量，藉由由此減去濾紙的質量，算出乾燥後之樣品質量：M₁(g)。 (5) The mass of the filter paper and the sample were measured, and the mass of the dried sample was calculated by subtracting the mass of the filter paper: M ₁ (g).

(6)將膠體乳液之基重G_BW(g/m²)以下述式：G_BW(g/m²)=[M₀(g)-M₁(g)]/A(m²)算出。 (6) Calculating the basis weight G _BW (g/m ² ) of the colloidal emulsion by the following formula: G _BW (g/m ² )=[M ₀ (g)-M ₁ (g)]/A(m ² ) .

且，為了減少誤差，自複數吸收性物品中採取複數樣品使樣品之總面積超過100cm²，重複複數次實驗，採用其平均值。 Further, in order to reduce the error, a plurality of samples were taken from the complex absorbent article so that the total area of the sample exceeded 100 cm ² , and the experiment was repeated for a plurality of experiments, and the average value thereof was used.

本發明之吸收性物品中，液體透過性層為不織布或織布時，該不織布或織布以親水化處理過較佳。作為上述親水化處理，有舉出在不織布或織布纖維的表面上塗覆親水劑、對不織布或織布的原料之合成樹脂中混合親 水劑等。在液體透過性層上成為交雜地共存來自烴基、體液滑性賦予劑等之親油性區域、與來自親水劑之親水性區域，而更能發揮滑落性能，這是因為使體液容易迅速地移動至吸收體。 In the absorbent article of the present invention, when the liquid permeable layer is a nonwoven fabric or a woven fabric, the nonwoven fabric or woven fabric is preferably hydrophilized. As the hydrophilization treatment, there is a synthetic resin in which a hydrophilic agent is applied to the surface of the non-woven fabric or the woven fabric, and the raw material of the non-woven fabric or the woven fabric is mixed. Aqueous agent, etc. In the liquid permeable layer, the lipophilic region derived from the hydrocarbon group or the body fluid slip imparting agent and the hydrophilic region derived from the hydrophilic agent are coexisting, and the sliding property is more exhibited because the body fluid is easily moved quickly. To the absorber.

上述膠體乳液並無特別限制，能夠製造。 The above colloidal emulsion is not particularly limited and can be produced.

例如藉由在加熱後的乳液中添加膠體化劑後再混合而製造塗佈液，且藉由將該塗佈液塗佈在應塗佈膠體乳液的吸收性物品之液體透過性層上，能夠製造吸收性物品。 For example, a coating liquid is prepared by adding a colloidizing agent to the heated emulsion, followed by mixing, and by applying the coating liquid to the liquid permeable layer of the absorbent article to which the colloidal emulsion is applied, Manufacture of absorbent articles.
