Description

吸收性物品 Absorbent articles

本發明主要係關於尿液吸收墊片、失禁墊片、拋棄式尿布、生理用衛生棉、分泌物之護墊等之吸收性物品，特別係關於具備抗菌劑之吸收性物品。 The present invention mainly relates to absorbent articles such as urine absorbing pads, incontinence pads, disposable diapers, sanitary napkins, secretion pads, etc., and particularly relates to absorbent articles with antibacterial agents.

歷來，已習知藉由在前述吸收性物品中具有抗菌劑，以抑制尿液或經血等體液中所含之細菌的繁殖，從而減低肌膚問題或抑制惡臭產生之技術。由於前述抗菌劑係透過與體液的接觸，對體液中所含之細菌等之抗菌效果始顯現，因此理想係均勻地配置於吸收體液部分之全體。 In the past, there has been a conventional technology for reducing skin problems or suppressing malodor by having antibacterial agents in the aforementioned absorbent articles to inhibit the reproduction of bacteria contained in body fluids such as urine or menstrual blood. Since the aforementioned antibacterial agent has an antibacterial effect on bacteria contained in the body fluid through contact with the body fluid, it is ideal to be uniformly arranged in the entire body fluid absorption part.

作為在吸收性物品中配置抗菌劑之手段，有藉由於進行吸收體的積纖時將紙漿纖維與粉體狀的抗菌劑一同混合，從而使之分散並混入吸收體中之技術，然而對於未與粉體狀的抗菌劑接觸之體液不會顯現抗菌效果，因此此方法抗菌效果並不充分。此外，作為另一手段，有將溶解於液體之抗菌劑噴霧或塗佈至吸收體的表面上之技術，然而將液體塗佈加工於吸收體有致體液的吸收性能惡化之虞。 As a means of disposing an antibacterial agent in an absorbent article, there is a technique of mixing pulp fibers with a powdered antibacterial agent during fiber accumulation of the absorbent body to disperse and mix it into the absorbent body. Body fluids in contact with powdered antibacterial agents will not exhibit antibacterial effects, so the antibacterial effect of this method is not sufficient. In addition, as another method, there is a technique of spraying or coating an antibacterial agent dissolved in a liquid on the surface of the absorber. However, applying the liquid to the absorber may deteriorate the absorption performance of body fluids.

另一方面，下述專利文獻1中揭露一種吸收性物品，其係吸收體具有第1吸收層與位於該第1吸收層的非肌膚相對面側之第1片 材；前述第1片材係具有複數個從肌膚相對面側向非肌膚相對面側凹陷之凹部，且複數個前述凹部各自配置有抗菌劑。 On the other hand, the following Patent Document 1 discloses an absorbent article, which is an absorbent body having a first absorbent layer and a first sheet located on the non-skin facing side of the first absorbent layer Material; The first sheet has a plurality of concave portions recessed from the skin-facing surface side to the non-skin-facing surface side, and each of the plurality of the concave portions is provided with an antibacterial agent.

此外，下述專利文獻2中揭露一種吸收性物品，其係表面片材的肌膚側之最外表面或表面片材的吸收體側之面上配置有抗菌性片材；且前述抗菌性片材係具有含有親水性纖維層與疏水性纖維層之片材狀基材，及形成於前述片材狀基材的前述親水性纖維層上並且由抗菌性組成物所構成之抗菌性組成物層；且前述抗菌性片材的前述抗菌性組成物層側，係透過接著劑貼著於前述表面片材；且前述抗菌性組成物係含有於常溫下為固體並且溶解於體液之熱可塑性水溶性聚合物與抗菌劑。 In addition, the following Patent Document 2 discloses an absorbent article in which an antibacterial sheet is arranged on the outermost surface of the surface sheet on the skin side or the surface of the surface sheet on the absorber side; and the aforementioned antibacterial sheet It has a sheet-like substrate containing a hydrophilic fiber layer and a hydrophobic fiber layer, and an antibacterial composition layer formed on the aforementioned hydrophilic fiber layer of the aforementioned sheet-like substrate and composed of an antibacterial composition; And the antibacterial composition layer side of the antibacterial sheet is attached to the surface sheet through an adhesive; and the antibacterial composition contains a thermoplastic water-soluble polymer that is solid at room temperature and dissolves in body fluids. And antibacterial agents.

【專利文獻2】日本專利第5096736號公報 [Patent Document 2] Japanese Patent No. 5096736

上述專利文獻1中，記載藉由在吸收體中具備具有凹部之第1片材，被此吸收體吸收之體液沿著前述第1片材的凹部迅速地擴散於吸收體中，且與配置於前述第1片材的凹部之抗菌劑接觸，從而發揮抗菌效果之作用效果，然而由於未到達此第1片材的凹部而被配置於第1片材 的肌膚側之第1吸收層及表面片材、包覆吸收體之包覆片材等吸收之體液並未與抗菌劑接觸，從而未顯現抗菌劑的抗菌效果，因此有從如此之被第1吸收層、表面片材、包覆片材等吸收之體液產生惡臭之虞。 The above-mentioned Patent Document 1 describes that by providing a first sheet having a recessed portion in the absorbent body, the body fluid absorbed by the absorbent body rapidly diffuses in the absorbent body along the recessed portion of the first sheet and is arranged in the absorbent body. The antibacterial agent in the concave portion of the first sheet is in contact with each other to exert the antibacterial effect. However, the concave portion of the first sheet is not reached and it is placed on the first sheet. The body fluids absorbed by the first absorbent layer and the surface sheet on the skin side, and the covering sheet covering the absorbent body are not in contact with the antibacterial agent, so the antibacterial effect of the antibacterial agent is not displayed. The body fluid absorbed by the absorbent layer, surface sheet, covering sheet, etc. may generate malodor.

另一方面，上述專利文獻2中，記載由於抗菌性片材係使用溶解於體液之熱可塑性水溶性聚合物作為附著於片材狀基材之抗菌性組成物中之抗菌劑的載體，因此熱可塑性水溶性聚合物透過與體液接觸而溶解，其結果，熱可塑性水溶性聚合物內的抗菌劑被放出並且發揮抗菌效果之作用效果，然而由於抗菌劑從抗菌性片材被釋放出並與體液一同流出，因此體液排出後幾乎沒有抗菌劑殘留於抗菌性片材上。因此，有從附著於肌膚面之體液及被表面片材吸收之體液產生惡臭之虞。此外，由於由熱可塑性水溶性聚合物與抗菌劑所構成之抗菌性組成物層，係透過噴霧塗佈加工等塗佈加工於抗菌性片材的親水性纖維層上，因此儘管預先於纖維的表面附著親水化劑而賦予其親水性，惟由於此親水化劑上進一步塗佈覆蓋有抗菌性組成物層，故由前述親水化劑產生之親水性的效果無法充分地發揮，而有吸收性能降低之虞。 On the other hand, the above-mentioned Patent Document 2 describes that since the antibacterial sheet uses a thermoplastic water-soluble polymer dissolved in body fluids as a carrier for the antibacterial agent attached to the antibacterial composition of the sheet-like substrate, the heat The plastic water-soluble polymer dissolves through contact with body fluids. As a result, the antibacterial agent in the thermoplastic water-soluble polymer is released and exerts an antibacterial effect. However, the antibacterial agent is released from the antibacterial sheet and interacts with the body fluid. Since the body fluids are discharged together, almost no antibacterial agent remains on the antibacterial sheet. Therefore, there is a risk of generating malodor from body fluids attached to the skin surface and body fluids absorbed by the surface sheet. In addition, since the antibacterial composition layer composed of a thermoplastic water-soluble polymer and an antibacterial agent is applied to the hydrophilic fiber layer of the antibacterial sheet through spray coating processing or the like. Hydrophilizing agent is attached to the surface to give it hydrophilicity. However, since this hydrophilizing agent is further coated with an antibacterial composition layer, the hydrophilic effect produced by the aforementioned hydrophilizing agent cannot be fully exerted, and it has absorption performance. Reduce the risk.

因此本發明主要之課題在於提供一種吸收性物品，其可充分地發揮由抗菌劑產生之抗菌效果，並且不會造成吸收性能降低。 Therefore, the main subject of the present invention is to provide an absorbent article that can fully exert the antibacterial effect produced by the antibacterial agent without causing a decrease in absorption performance.

〔尿液吸收墊片的基本構造之一例〕 [An example of the basic structure of a urine absorbing pad]

本發明之尿液吸收墊片1，如圖1~圖3所示，主要係由防漏片材2、表面片材3、吸收體4、外裝片材5、側邊不織布6、6、及第二片材8所構成；且前述防漏片材2，係由聚乙烯片材等所構成；前述表面片材3，係形成與著用者的肌膚之接觸面並且使尿液等迅速地透過；前述吸收體4，係介在並裝設於此兩片材2、3之間；前述外裝片材5，係覆蓋尿液吸收墊片1之最外面(非肌膚接觸面)；前述側邊不織布6、6，係形成左右一對的立體摺邊BS、BS，前述左右一對的立體摺邊BS、BS係以前述吸收體4的略側緣部作為立起基端，且於至少包含著用者的排尿口部之前後方向的指定區間內向肌膚側突出；前述第二片材8，係根據需要配設於前述表面片材3與吸收體4之間；並且於吸收體4的周圍，於其上下端緣部，防漏片材2、表面片材3以及外裝片材5的外緣部透過熱熔膠等接著劑或熱密封、超音波密封等接合手段而接合；此外，於其兩側緣部，較吸收體4向側方延伸出之防漏片材2、表面片材3、外裝片材5及側邊不織布6透過熱熔膠等接著劑或熱密封、超音波密封等接合手段而接合。 The urine absorbing pad 1 of the present invention, as shown in Figures 1 to 3, is mainly composed of a leak-proof sheet 2, a surface sheet 3, an absorbent body 4, an exterior sheet 5, and side non-woven fabrics 6, 6, And the second sheet 8; and the aforementioned leak-proof sheet 2 is composed of polyethylene sheet, etc.; the aforementioned surface sheet 3 forms a contact surface with the user’s skin and makes urine and the like quickly The aforementioned absorbent body 4 is interposed and installed between the two sheets 2 and 3; the aforementioned exterior sheet 5 covers the outermost (non-skin contact surface) of the urine absorption pad 1; The side non-woven fabrics 6, 6 are formed with a pair of left and right three-dimensional hems BS, BS, and the aforementioned pair of left and right three-dimensional hems BS, BS are based on the slightly side edges of the absorbent body 4 as the standing base ends. At least including the user’s urinary mouth, protruding toward the skin in a designated section in the front and back direction; the second sheet 8 is arranged between the surface sheet 3 and the absorber 4 as necessary; and in the absorber 4 At its upper and lower end edges, the outer edges of the leak-proof sheet 2, the surface sheet 3 and the exterior sheet 5 are joined by hot-melt adhesive or other bonding means, heat sealing, ultrasonic sealing, etc.; In addition, at the edges of both sides, the leak-proof sheet 2, the surface sheet 3, the exterior sheet 5, and the side non-woven fabric 6 extending laterally from the absorber 4 are sealed by hot melt adhesive or other adhesive or heat-sealed , Ultrasonic sealing and other bonding means.

以下進一步對尿液吸收墊片1的構造進行詳細說明： The structure of the urine absorbing pad 1 will be further described in detail below:

前述防漏片材2，係使用聚乙烯等至少具有阻水性的片材，但近年從防止悶熱的觀點而言傾向使用具有透濕性者。此阻水、透濕性片材，理想係使用微多孔性片材，前述微多孔性片材，係於聚乙烯或聚丙烯等烯烴系樹脂中熔融混練無機填充劑，使片材成形後，藉由向一軸或二軸方向延伸而獲得。前述防漏片材2，亦可使用塑膠膜與不織布積層而成的聚乙烯積層不織布。 The aforementioned leak-proof sheet 2 uses a sheet having at least water barrier properties such as polyethylene, but in recent years, it has tended to use those having moisture permeability from the viewpoint of preventing stuffiness. This water-blocking and moisture-permeable sheet is preferably a microporous sheet. The aforementioned microporous sheet is melted and kneaded with an olefin resin such as polyethylene or polypropylene, and an inorganic filler is melted and kneaded to form the sheet. Obtained by extending to one axis or two axes. The aforementioned leak-proof sheet 2 may also be a polyethylene laminated non-woven fabric formed by laminating a plastic film and a non-woven fabric.

接著，前述表面片材3，理想係使用有孔或無孔的不織布 或多孔性塑膠片材等。構成不織布的素材纖維，除了聚乙烯或聚丙烯等之烯烴系、聚酯系、聚醯胺系等之合成纖維以外，亦可為嫘縈或銅銨等之再生纖維、棉等之天然纖維，並且可使用由水針法、紡黏法、熱熔黏合法、熔噴法、針軋法等適當的加工法所獲得之不織布。此等加工法中，水針法以富有柔軟性與懸垂性之特點而優異，熱熔黏合法以蓬鬆且壓縮復原性高之特點為優異。於前述表面片材3形成多數透孔之情形，體液會被迅速地吸收，且乾爽性優異。不織布的纖維，可為長纖維或短纖維任一者，但由於理想係呈現毛巾質地的質感，因此以使用短纖維為佳。此外，為了便於壓紋處理，使用熔點較低的聚乙烯或聚丙烯等之烯烴系纖維者為佳。此外，亦可理想地使用將熔點高的纖維作為芯而熔點低的纖維作為鞘的芯鞘型纖維或並列型纖維、分割型纖維之複合纖維。 Next, the aforementioned surface sheet 3, ideally a non-woven fabric with or without holes Or porous plastic sheet, etc. In addition to synthetic fibers such as polyethylene or polypropylene, such as olefin, polyester, and polyamide, the material fibers constituting the non-woven fabric may also be recycled fibers such as rayon or cupra, and natural fibers such as cotton. In addition, non-woven fabrics obtained by appropriate processing methods such as water needle method, spun bonding method, hot melt bonding method, melt blown method, and needle rolling method can be used. Among these processing methods, the water jet method is excellent in terms of flexibility and drape, and the hot melt bonding method is excellent in terms of fluffy and high compression recovery. In the case where a large number of through holes are formed in the aforementioned surface sheet 3, body fluids are quickly absorbed, and the dryness is excellent. The fibers of the non-woven fabric may be either long fibers or short fibers, but since the ideal is to present a towel-like texture, it is better to use short fibers. In addition, in order to facilitate the embossing process, it is better to use olefin fibers such as polyethylene or polypropylene with a lower melting point. In addition, a core-sheath type fiber or a composite fiber of a side-by-side type fiber or a split type fiber in which a fiber with a high melting point is used as a core and a fiber with a low melting point is used as a sheath can also be preferably used.

介於前述防漏片材2與表面片材3之間的吸收體4，例如係由棉狀紙漿與高吸水性聚合物所構成。前述高吸水性聚合物係例如作為粒狀粉混入構成吸收體4的紙漿中。前述紙漿，可列舉：由從木材所獲得之化學紙漿、溶解紙漿等之纖維素纖維、或嫘縈、醋酸酯等之人工纖維素纖維所構成者；相較於闊葉樹紙漿，以功能及價格面而言，更理想為使用纖維長度較長的針葉樹紙漿。 The absorbent body 4 interposed between the aforementioned leak-proof sheet 2 and the surface sheet 3 is made of cotton-like pulp and super absorbent polymer, for example. The aforementioned super absorbent polymer system is mixed into the pulp constituting the absorber 4 as granular powder, for example. The aforementioned pulp includes: chemical pulp obtained from wood, cellulose fibers such as dissolving pulp, or artificial cellulose fibers such as rayon and acetate; compared with hardwood pulp, it is more functional and cost-effective In other words, it is more desirable to use softwood pulp with a longer fiber length.

此外，亦可於吸收體4中混合合成纖維。前述合成纖維，例如可使用：聚乙烯或聚丙烯等之聚烯烴系、聚對苯二甲酸乙二酯或聚對苯二甲酸丁二酯等之聚酯系、尼龍等之聚醯胺系、以及此等之共聚物等，亦可為混合此等二種者。此外，亦可使用將熔點高的纖維作為芯而熔點低的纖維作為鞘之芯鞘型纖維或並列型纖維、分割型纖維等之複合纖維。前 述合成纖維，為了使其對體液具有親和性，在疏水性纖維的情形，理想係使用藉由親水化劑進行過表面處理者。 In addition, synthetic fibers may be mixed in the absorber 4. For the aforementioned synthetic fibers, for example, polyolefin series such as polyethylene or polypropylene, polyester series such as polyethylene terephthalate or polybutylene terephthalate, polyamide series such as nylon, etc. can be used. And these copolymers, etc., may also be a mixture of these two types. In addition, composite fibers such as core-sheath fibers, side-by-side fibers, split-type fibers, etc., which use fibers with a high melting point as the core and fibers with a low melting point as the sheath can also be used. before In order to make the synthetic fibers have affinity for body fluids, in the case of hydrophobic fibers, it is desirable to use those that have been surface-treated with a hydrophilizing agent.

前述高吸水性聚合物係除了「粒子」以外亦包含「粉體」。高吸水性聚合物，可直接使用用於此種吸收性物品之粒徑者，並且平均粒徑為1000μm以下，理想係未吸收時之粒徑為106μm以上者為全體的99重量%以上，特別係以150~850μm者為全體的99重量%以上為佳。理想係未吸收時的平均粒徑為250~500μm左右。此外，高吸水性聚合物理想係吸收後的平均粒徑為未吸收時的平均粒徑的三倍以上，具體而言為500μm以上。另外，未吸收時的高吸水性聚合物的平均粒徑，係指重量基準粒度分布之積算值50%時之粒徑。此情況中之重量基準粒度分布係以JISZ8815-1994為基準而測定。亦即，藉由將內徑150mm、深度45mm的710μm、500μm、300μm、150μm及106μm的篩孔的篩子，以篩孔較窄的篩放下面的方式重疊，於最上面的篩孔最大的710μm的篩子上放入測定樣品50g，使用搖篩器搖篩10分鐘，並且測定各個篩子上殘留之測定樣品的重量，以最初的測定樣品的重量為基準求出各個篩子上殘留之測定樣品的重量%而測定。 The aforementioned super absorbent polymer system also includes "powder" in addition to "particles". The super absorbent polymer can be directly used for the particle size of such absorbent articles, and the average particle size is 1000μm or less, ideally, the particle size of 106μm or more when not absorbed is 99% by weight or more of the whole, especially It is preferable that the 150-850μm is 99% by weight or more of the total. Ideally, the average particle size when not absorbed is about 250 to 500 μm. In addition, the super absorbent polymer desirably has an average particle size after absorption that is three times or more the average particle size when it is not absorbed, specifically 500 μm or more. In addition, the average particle size of the superabsorbent polymer when it is not absorbed refers to the particle size at 50% of the cumulative value of the particle size distribution on a weight basis. The weight-based particle size distribution in this case is measured based on JISZ8815-1994. That is, by overlapping the sieves of 710μm, 500μm, 300μm, 150μm and 106μm with an inner diameter of 150mm and a depth of 45mm with the narrower sieve placed underneath, the uppermost sieve with the largest opening is 710μm. Put 50g of the measurement sample on the sieve, shake the sieve for 10 minutes, and measure the weight of the measurement sample remaining on each sieve. Determine the weight of the measurement sample remaining on each sieve based on the weight of the initial measurement sample % And determined.

高吸水性聚合物的基重的量，可依據該吸收體4的用途所要求之吸收量適當地制定。因此，雖然無法一概而論，但可為50~350g/m²。當聚合物的基重的量未滿50g/m²時難以確保吸收量。如果超過350g/m²的話，則不僅效果飽和，且會因高吸水性聚合物的過剩而予以顆粒的不適感。 The amount of the basis weight of the super absorbent polymer can be appropriately determined according to the amount of absorption required by the application of the absorbent body 4. Therefore, although it cannot be generalized, it can be 50~350g/m ² . When the basis weight of the polymer is less than 50 g/m ² , it is difficult to ensure the absorption. If it exceeds 350 g/m ² , not only the effect is saturated, but the superabsorbent polymer is excessive and gives a feeling of discomfort to particles.

前述吸收體4，係相對於紙漿及高吸水性聚合物的合計重量之高吸水性聚合物的比率為5~90重量%，特別係以30~70重量%為 佳。若高吸水性聚合物的比率較小於5重量%，則有吸水能力不足之虞。另一方面，若大於90重量%，則會強烈感受到高吸水性聚合物的顆粒感(粒子感)，從而使用感降低。 The aforementioned absorbent body 4 has a ratio of 5 to 90% by weight of the super absorbent polymer relative to the total weight of the pulp and super absorbent polymer, particularly 30 to 70% by weight good. If the ratio of the super absorbent polymer is less than 5% by weight, the water absorption capacity may be insufficient. On the other hand, if it exceeds 90% by weight, the graininess (particle feeling) of the super absorbent polymer is strongly felt, and the feeling in use is reduced.

On the other hand, since the antibacterial agent 12 in the aforementioned fiber is loaded by kneading inside the fiber 10, it remains in the state of being supported in the fiber 10 and resists the body fluid absorbed by the surface sheet 3 or adheres to it. The body fluids of the user’s skin, etc., exist near the user The body fluid on the skin surface exerts an antibacterial effect. In this way, the antibacterial agent 13 in the fiber treatment agent and the antibacterial agent 12 in the fiber exert their antibacterial effects in different forms, so that the malodor caused by urination can be reliably suppressed and the antibacterial effect by the antibacterial agent can be fully exhibited.

相對於此，於過去具備抗菌劑之吸收性物品中，如圖7所示，由於係在表面附著有纖維處理劑之纖維的表面，抗菌劑覆蓋前述纖維處理劑而塗佈，因此透過排尿，抗菌劑及纖維處理劑流失且抗菌劑不殘存於表面片材上，從而有從被表面片材吸收之體液或附著於著用者的肌膚面之體液等產生惡臭之虞。 In contrast, in the conventional absorbent articles equipped with antibacterial agents, as shown in Fig. 7, the antibacterial agent is coated on the surface of the fiber with the fiber treatment agent attached to the surface, so that the antibacterial agent is applied to cover the fiber treatment agent. The antibacterial agent and the fiber treatment agent are lost and the antibacterial agent does not remain on the surface sheet, so there is a risk of generating malodor from body fluids absorbed by the surface sheet or body fluids attached to the skin surface of the user.

此外，於過去具備抗菌劑之吸收性物品中，如前所述，由於係在表面附著有纖維處理劑之纖維的表面，抗菌劑覆蓋前述纖維處理劑而塗佈，因此有所塗佈覆蓋之抗菌劑阻礙纖維處理劑的效果，而使吸收性能惡化之虞。相對於此，本發明之尿液吸收墊片1中，由於纖維處理劑中抗菌劑13係藉由混合入附著於纖維10的表面之纖維處理劑11而被配設，因此不會阻礙纖維處理劑11的效果，且不會有吸收性能惡化之情形。 In addition, in conventional absorbent articles equipped with antibacterial agents, as mentioned above, since the surface of the fiber with the fiber treatment agent adhered to the surface, the antibacterial agent is applied to cover the aforementioned fiber treatment agent, so it is coated with The antibacterial agent hinders the effect of the fiber treatment agent and may deteriorate the absorption performance. In contrast, in the urine absorbing pad 1 of the present invention, since the antibacterial agent 13 in the fiber treatment agent is arranged by mixing the fiber treatment agent 11 attached to the surface of the fiber 10, it does not hinder the fiber treatment The effect of agent 11, and there will be no deterioration in absorption performance.

從確實地發揮如此之效果之觀點而言，理想係構成為相較於伴隨排尿而從前述抗菌性不織布(表面片材3)溶出之抗菌劑的量，排尿後殘存於前述抗菌性不織布之抗菌劑的量較多。藉此，即使在排尿後，亦於接近著用者的肌膚面處配置有較多的抗菌劑，從而可維持靠近肌膚面位置的抗菌效果，且變得更衛生。如此之構成，可藉由適當調整纖維中抗菌劑12的含量與纖維處理劑中抗菌劑13的含量而達成。具體而言，以抗菌性不織布的每單位體積所含有之纖維中抗菌劑12的含量較纖維處理劑 中抗菌劑13的含量大為佳。藉此，即使透過排尿而從指定部分的抗菌性不織布溶出纖維處理劑中抗菌劑13，亦有較溶出之纖維處理劑中抗菌劑13的量為多量的纖維中抗菌劑12會停留在纖維10中。 From the viewpoint of reliably exerting such an effect, the ideal system is constituted so that compared to the amount of antibacterial agent eluted from the antibacterial nonwoven fabric (surface sheet 3) accompanying urination, the antibacterial agent remaining in the antibacterial nonwoven fabric after urination The amount of agent is larger. Thereby, even after urination, more antibacterial agents are placed near the skin surface of the user, so that the antibacterial effect near the skin surface can be maintained, and it becomes more hygienic. Such a configuration can be achieved by appropriately adjusting the content of the antibacterial agent 12 in the fiber and the content of the antibacterial agent 13 in the fiber treatment agent. Specifically, the content of antibacterial agent 12 per unit volume of the antibacterial nonwoven fabric is higher than that of the fiber treatment agent The content of antibacterial agent 13 is great. Thereby, even if the antibacterial agent 13 in the fiber treatment agent is eluted from the designated portion of the antibacterial non-woven fabric through urination, the amount of antibacterial agent 13 in the fiber treatment agent is larger than that of the eluted fiber treatment agent. The antibacterial agent 12 in the fiber will stay on the fiber 10. in.
