The top sheet 60 has a plurality of ridges 61 and grooves 62 extending in parallel in the front-rear direction of the disposable diaper on the skin contact surface. The plurality of ridges 61 and the plurality of grooves 62 are alternately arranged in the width direction. The non-skin abutment surface of the top sheet is flat.
脊部的基重比溝部的基重更高。脊部的基重理想是15~50g/m2，更理想是20~40g/m2，最理想是28~35g/m2。溝部的基重理想是5~20g/m2，更理想是8~18g/m2，最 理想是10~15g/m2。頂面薄片的整體基重為25g/m2的時候，理想是脊部的基重為28~32g/m2，溝部的基重為10~15g/m2。 The basis weight of the ridge is higher than the basis weight of the groove. The basis weight of the ridge is preferably 15 to 50 g/m 2 , more preferably 20 to 40 g/m 2 , and most preferably 28 to 35 g/m 2 . The basis weight of the groove portion is preferably 5 to 20 g/m 2 , more preferably 8 to 18 g/m 2 , and most preferably 10 to 15 g/m 2 . When the total basis weight of the top sheet is 25 g/m 2 , the basis weight of the ridge portion is preferably 28 to 32 g/m 2 , and the basis weight of the groove portion is 10 to 15 g/m 2 .
在頂面薄片的溝部62，存在有開孔或密度小的部分為理想。於此，「密度小」是指：密度0.015g/cm3以下的情況。藉由在頂面薄片的溝部存在有開孔或密度小的部分，當尿迅速被排出時，尿可容易通過頂面薄片的溝部62。 It is preferable that the groove portion 62 of the top sheet has a hole having a small opening or a small density. Here, the "small density" means a case where the density is 0.015 g/cm 3 or less. By having a hole or a portion having a small density in the groove portion of the top sheet, urine can easily pass through the groove portion 62 of the top sheet when the urine is quickly discharged.
鄰接的脊部61的頂點間的距離理想是1~10mm，更理想是2~8mm，最理想是3~5mm，最典型的是約4mm。脊部61的寬幅理想是1~10mm，更理想是2~5mm，理想是3~4mm，溝部62的寬幅理想是0.5~20mm，更理想是1.0~10mm，最理想是2~5mm。最典型的是脊部61的寬幅約3.0mm，溝部62的寬幅約1.0mm。 The distance between the apexes of the adjacent ridges 61 is desirably 1 to 10 mm, more preferably 2 to 8 mm, most preferably 3 to 5 mm, and most typically about 4 mm. The width of the ridge 61 is preferably 1 to 10 mm, more preferably 2 to 5 mm, and most preferably 3 to 4 mm, and the width of the groove portion 62 is preferably 0.5 to 20 mm, more preferably 1.0 to 10 mm, and most preferably 2 to 5 mm. Most typically, the width of the ridge 61 is about 3.0 mm and the width of the groove 62 is about 1.0 mm.
用於頂面薄片60的不織布理想是包含熱熔著纖維彼此的交點的纖維。在這樣的纖維，例如有由熱可塑性聚合物材料形成的纖維，聚乙烯及聚丙烯等的聚烯烴、聚對苯二甲酸乙二醇酯等的聚酯、聚醯胺等。又，在這樣的纖維也可使用由複數個熱可塑性聚合物材料的組合所形成的芯鞘型、並列型的複合纖維。 The nonwoven fabric used for the top sheet 60 is desirably a fiber comprising intersections of thermally fusible fibers with each other. Examples of such fibers include fibers formed of a thermoplastic polymer material, polyolefins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate, and polyamine. Further, a core-sheath type or a side-by-side type composite fiber formed of a combination of a plurality of thermoplastic polymer materials can be used for such a fiber.
頂面薄片為一様的基重的不織布時，關於在配置吸收擴散薄片的位置以外排尿時、在表面流的尿的吸收，往吸收體的浸透慢，且尿從頂面薄片上到被吸收為止需要時間，而會發生尿的洩漏。本發明的用後即棄式紙尿布，頂面薄片具有脊部與溝部，由於溝部的基重低，所以頂面薄 片上的尿通過溝部迅速朝下層移動，可防止尿在頂面薄片的表面流而洩漏的情況。 When the top sheet is a basis weight non-woven fabric, the absorption of urine flowing on the surface when urinating outside the position where the diffusion sheet is disposed is slow to permeate the absorbent body, and the urine is absorbed from the top sheet to the absorbed sheet. It takes time until a leak of urine occurs. The disposable disposable diaper of the present invention, the top sheet has a ridge portion and a groove portion, and the top surface is thin due to the low basis weight of the groove portion The urine on the sheet moves rapidly downward through the groove portion, preventing urine from leaking on the surface of the top sheet and leaking.
接著，參照圖4，說明製作具有複數個脊部61與複數個溝部62的頂面薄片60用的方法的一例。圖4(a)是說明在為了製作不織布所形成的纖維網形成脊部及溝部的工程的圖，圖4(b)表示形成有脊部及溝部的纖維網的寬方向(CD)的剖面的圖。藉由裁切機等的纖維網形成手段所形成的纖維網210是朝吸筒220被搬送。然後，從吹出部230的噴嘴噴吹被加熱的流體流231分開纖維網210的一部分，而在纖維網210形成脊部211及溝部212。因流體流231而朝與作為纖維網210的進行方向的機械方向(MD)正交的寬方向(CD)被分開的纖維在脊部211聚集。因此，因為在脊部211堆積有相當於溝部212的區域的纖維，所以脊部211的基重變高。又，由於藉由流體流231纖維朝寬方向(CD)被吹走，所以溝部212的基重低。 Next, an example of a method for producing the top sheet 60 having a plurality of ridge portions 61 and a plurality of groove portions 62 will be described with reference to Fig. 4 . Fig. 4 (a) is a view for explaining a process of forming a ridge portion and a groove portion in a web formed by forming a nonwoven fabric, and Fig. 4 (b) is a view showing a width direction (CD) of a web in which a ridge portion and a groove portion are formed. Figure. The web 210 formed by the web forming means such as a cutter is conveyed toward the suction tube 220. Then, a portion of the fiber web 210 is separated by blowing the heated fluid stream 231 from the nozzle of the blowing portion 230, and the ridge portion 211 and the groove portion 212 are formed in the fiber web 210. The fibers separated by the fluid flow 231 toward the width direction (CD) orthogonal to the machine direction (MD) of the progress direction of the web 210 are gathered at the ridges 211. Therefore, since the fibers corresponding to the region of the groove portion 212 are deposited on the ridge portion 211, the basis weight of the ridge portion 211 is increased. Further, since the fibers of the fluid stream 231 are blown away in the width direction (CD), the basis weight of the groove portion 212 is low.
從吹出部230被吹出的流體流231也可為空氣、水蒸汽這類的氣體，也可為水等的液體。又，也可在氣體含有固體或液體的微粒子的氣懸膠體。 The fluid stream 231 blown out from the blowing portion 230 may be a gas such as air or water vapor, or may be a liquid such as water. Further, it is also possible to use an aerosol in which the gas contains solid or liquid fine particles.
用後即棄式紙尿布1在頂面薄片60與吸收體50之間具有吸收擴散薄片90。吸收擴散薄片90是為了迅速吸收被排出到頂面薄片60的穿用者的尿且予以擴散而設。吸收擴散薄片90是由親水性且液透過性的材料形成。例如，可將由親水性且液透過性的纖維形成的織布、不織布 等作為吸收擴散薄片90使用。吸收擴散薄片90理想是由親水性且液透過性的纖維形成的不織布。 The disposable disposable diaper 1 has an absorption diffusion sheet 90 between the top sheet 60 and the absorbent body 50. The diffusion sheet 90 is provided to rapidly absorb and diffuse the urine of the wearer discharged to the top sheet 60. The absorption diffusion sheet 90 is formed of a hydrophilic and liquid permeable material. For example, a woven fabric or a non-woven fabric formed of hydrophilic and liquid permeable fibers can be used. It is used as the absorption diffusion sheet 90. The absorption diffusion sheet 90 is desirably a nonwoven fabric formed of hydrophilic and liquid permeable fibers.
吸收擴散薄片90是如圖1及圖2所示，設在吸收體50的面方向的區域的一部分的區域。 The absorption diffusion sheet 90 is a region provided in a part of a region in the surface direction of the absorber 50 as shown in FIGS. 1 and 2 .
用後即棄式紙尿布是男子用的時候，將吸收體的前後方向長度設為L0時，吸收擴散薄片的前端91是位在從吸收體的前端54起0.0L0~0.10L0的位置，理想是位在0.07L0~0.095L0的位置。吸收擴散薄片的後端92是位在從吸收體的前端54起0.50L0~0.85L0的位置。 A disposable diaper is the formula used when the man, the absorbent body front-rear direction of the length L 0 is set, the diffusion front end of the absorbent sheet 91 is located in the absorbent body from the front end 54 from the 0.0L 0 ~ 0.10L 0 position, is located in the ideal 0.07L 0 ~ 0.095L 0 position. Diffusing absorbent sheet 92 is located in the rear end position from the front end of the absorbent body 54 from 0.50L 0 ~ 0.85L 0's.
用後即棄式紙尿布為女子用的時候，吸收擴散薄片的前端91是位在從吸收體的前端54起0.20L0~0.35L0的位置，理想是位在0.25L0~0.30L0的位置。吸收擴散薄片的後端92是位在從吸收體的前端54起0.70L0~1.0L0的位置，理想是位在0.75L0~0.80L0的位置。 When a disposable paper diaper as a woman with a formula, the absorptive and diffusive sheet 91 is located in the front end of the absorbent body 54 from the front end from the position of 0.20L 0 ~ 0.35L 0, the bit is desirable 0.25L 0 ~ 0.30L 0 s position. Diffusing absorbent sheet 92 is located in the rear end of the absorbent body 54 from the front end from the position of 0.70L 0 ~ 1.0L 0, the bit position is desirable 0.75L 0 ~ 0.80L 0's.
吸收擴散薄片90是設在用後即棄式紙尿布1的與穿用者的尿的排出口對應的位置(排尿點)及其周邊的區域(吸收層)，亦即，設在吸收體50的面方向的區域的前腰圍區域12側的區域。在男子用的用後即棄式紙尿布與女子用的用後即棄式紙尿布由於吸收層的區域不同，所以在男子用的用後即棄式紙尿布與女子用的用後即棄式紙尿布設有吸收擴散薄片90的區域也不同。亦即，設有男子用的用後即棄式紙尿布的吸收擴散薄片90的區域與設有女子用的用後即棄式紙尿布的吸收擴散薄片90的區域相比靠近前腰圍區域12側。 The absorption diffusion sheet 90 is provided at a position (a urination point) corresponding to the discharge port of the wearer's urine of the disposable disposable diaper 1 and a peripheral region (absorption layer) thereof, that is, provided in the absorbent body 50. The area on the front waistline region 12 side of the area in the face direction. Disposable disposable diapers for men and disposable diapers for women are used in disposable diapers for men and disposables for women because of the different areas of the absorbent layer. The area in which the disposable diaper is provided with the absorption diffusion sheet 90 is also different. That is, the area of the absorbent diffusion sheet 90 provided with the disposable disposable diaper for men is closer to the front waistline region 12 side than the area of the absorbent diffusion sheet 90 provided with the disposable disposable diaper for women. .
在用後即棄式紙尿布的兩側部設有腿圍彈性構件70時，用後即棄式紙尿布是男子用的時候，吸收擴散薄片90的前端91比腿圍彈性構件70的前端71更位於前，用後即棄式紙尿布為女子用的時候，吸收擴散薄片90的前端91比腿圍彈性構件70的前端71更位於後。男子的時候，由於會有在前方迅速排出尿的傾向，所以在腿圍彈性構件70的應力無效的前方部分也有吸收擴散薄片90的存在為理想。 When the leg-surrounding elastic members 70 are provided on both side portions of the disposable disposable diaper, when the disposable disposable diaper is used for men, the front end 91 of the absorbent diffusion sheet 90 is longer than the front end 71 of the leg-surrounding elastic member 70. Further, when the disposable disposable diaper is used for women, the front end 91 of the absorbent diffusion sheet 90 is located further rearward than the front end 71 of the leg-surrounding elastic member 70. In the case of a man, there is a tendency to rapidly discharge urine in the front side, and therefore it is preferable to have the absorption diffusion sheet 90 in the front portion where the stress of the leg-surrounding elastic member 70 is invalid.
在用後即棄式紙尿布的前腰圍區域設有扣具用目標帶片150時，用後即棄式紙尿布為男子用時，吸收擴散薄片90的一部分重疊於目標帶片150，用後即棄式紙尿布為女子用時，吸收擴散薄片90沒有重疊於目標帶片150。藉由這樣的設計，可獲得在尿布的中央附近的部分吸收尿，往吸收體透過，防止所謂尿在目標帶片附近積存而洩漏的效果。 When the target waist piece 150 for the buckle is provided in the front waist region of the disposable disposable diaper, when the disposable disposable diaper is used for men, a part of the absorption diffusion sheet 90 is overlapped with the target tape 150, after use. When the disposable diaper is for women, the absorbing diffusion sheet 90 does not overlap the target belt 150. With such a design, it is possible to obtain a portion in the vicinity of the center of the diaper that absorbs urine and transmits it to the absorbent body, thereby preventing the so-called urine from being accumulated in the vicinity of the target tape piece and leaking.
本發明的用後即棄式紙尿布藉由在排尿位置配置吸收擴散薄片，由於吸收擴散薄片暫時吸收排尿之後的大量的尿，所以可防止尿在頂面薄片的表面流而洩漏的情況。在吸收擴散薄片被吸收的尿，之後慢慢移動到吸收體在吸收體被吸收。 In the disposable diaper of the present invention, by absorbing the diffusion sheet at the urination position, since the absorption diffusion sheet temporarily absorbs a large amount of urine after urination, it is possible to prevent urine from leaking on the surface of the top sheet and leaking. After absorbing the absorbed urine, the urine is slowly moved to the absorbent body and absorbed in the absorbent body.
本發明的用後即棄式紙尿布，是除了可藉由組合具有脊部及溝部的頂面薄片、以及與男女不同的排尿位置配合的吸收擴散薄片，有效率地經由吸收擴散薄片使尿往吸收體浸透之外，改善在偏離配置吸收擴散薄片的範圍的地方 的尿浸透，使尿漏不易發生。本發明的用後即棄式紙尿布，由於吸收擴散薄片在頻繁地吸收尿的區域以外的部分並不存在，所以可在產品相對於身體柔軟地貼合的狀態下進行安裝。 The disposable disposable diaper of the present invention is capable of efficiently absorbing urine through the absorption diffusion sheet by combining a top sheet having a ridge portion and a groove portion and an absorption diffusion sheet which is matched with a urination position different from that of men and women. In addition to the absorption of the absorber, the improvement is made in the range away from the range in which the diffusion sheet is disposed. The urine is soaked so that urine leakage is not easy to occur. In the disposable disposable diaper of the present invention, since the absorbent diffusion sheet does not exist in a portion other than the region where the urine is frequently absorbed, the product can be attached in a state where the product is softly attached to the body.
吸收擴散薄片的密度比頂面薄片的溝部的密度更大，且比頂面薄片的脊部的密度更小為理想。亦即，密度是在頂面薄片的溝部、吸收擴散薄片、頂面薄片的脊部的順序變大為理想。這裡，密度是指所謂每單位體積的質量。藉由密度的大小關係成為如此的方式，雖可使大量的尿落下，可是尿不易回到表面。更詳而言之，當尿大量被排出時，尿首先在頂面薄片的溝部積存。由於吸收擴散薄片的密度比頂面薄片的溝部的密度更大，所以在頂面薄片的溝部積存的尿，藉由毛細管現象的原理迅速移行到吸收擴散薄片而被吸收。在吸收擴散薄片被吸收的尿，雖然首先被保持在吸收擴散薄片，可是之後朝面方向擴散，並且移行到吸收體，在吸收體被吸收。當一旦被吸收的尿欲回到表面時，由於尿被擁抱在密度大的頂面薄片的脊部，所以液返回不易發生。 It is desirable that the density of the absorption diffusion sheet is larger than the density of the groove portion of the top sheet and smaller than the density of the ridge portion of the top sheet. That is, the density is preferably in the order of the groove portion of the top sheet, the absorbing diffusion sheet, and the ridge portion of the top sheet. Here, the density refers to the so-called mass per unit volume. This is the way by which the density relationship is such that a large amount of urine can be dropped, but the urine does not easily return to the surface. More specifically, when a large amount of urine is discharged, urine first accumulates in the groove portion of the top sheet. Since the density of the absorption diffusion sheet is larger than the density of the groove portion of the top sheet, the urine accumulated in the groove portion of the top sheet is quickly transferred to the absorption diffusion sheet by the principle of capillary action and absorbed. The urine in which the absorption diffusion sheet is absorbed, although first held in the absorption diffusion sheet, is then diffused in the surface direction and migrates to the absorber, and is absorbed in the absorber. When the absorbed urine is returned to the surface, since the urine is hugged in the ridge of the dense top sheet, liquid return does not easily occur.
吸收擴散薄片的密度理想是0.015~0.05g/cm3，更理想是0.017~0.04g/cm3，最理想是0.02~0.03g/cm3。頂面薄片的脊部的密度理想是0.015~0.06g/cm3，更理想是0.015~0.03g/cm3，最理想是0.015~0.02g/cm3。在頂面薄片的溝部的密度理想是0.010~0.02g/cm3，更理想是0.015~0.02g/cm3。 The density of the absorption diffusion sheet is desirably 0.015 to 0.05 g/cm 3 , more desirably 0.017 to 0.04 g/cm 3 , and most desirably 0.02 to 0.03 g/cm 3 . The density of the ridge portion of the top sheet is desirably 0.015 to 0.06 g/cm 3 , more desirably 0.015 to 0.03 g/cm 3 , and most desirably 0.015 to 0.02 g/cm 3 . The density of the groove portion of the top sheet is desirably 0.010 to 0.02 g/cm 3 , more preferably 0.015 to 0.02 g/cm 3 .
吸收擴散薄片的基重理想是20~60g/m2，更理想是25~50g/m2，最理想是30~40g/m2，最典型的是約40g/m2。 The basis weight of the absorption diffusion sheet is desirably 20 to 60 g/m 2 , more desirably 25 to 50 g/m 2 , most preferably 30 to 40 g/m 2 , and most typically about 40 g/m 2 .
吸收擴散薄片90理想是由尿的吸收速度比吸收構件51更快速的材料所形成。藉由由吸收速度快的材料形成，當尿迅速被排出時，吸收擴散薄片90可迅速吸收大量的尿。吸收擴散薄片90理想是由可逆吸收尿且得以放出的材料所形成。藉由由可逆吸收尿且得以放出的材料形成，一旦在吸收擴散薄片被吸收的尿，之後慢慢地移動到吸收體，在吸收體被吸收。另一方面，吸收構件51是被不可逆吸收尿，且一旦吸收的尿不容易放出的這類的材料所形成，或包含有這樣的材料為理想。又，吸收構件51雖是由吸收容量大的材料形成為理想，可是吸收擴散薄片90的吸收容量比吸收構件51的吸收容量更小為理想。作為這樣的材料，可例示1層或複數層構造的熱風不織布等的不織布，且可將該等作為吸收擴散薄片90使用。作為形成不織布的纖維，可舉聚丙烯(PP)的單纖維、或聚乙烯(PE)/聚對苯二甲酸乙二醇酯(PET)、PP/PE芯鞘或是並列的複合纖維等，可將該等的纖維的1種單獨或將複數予以組合使用。該等的纖維或不織布，是藉由在表面塗布親水性油劑或混入親水劑等賦予親水性。 The absorption diffusion sheet 90 is desirably formed of a material whose urine absorption speed is faster than that of the absorption member 51. By being formed of a material having a high absorption speed, the absorption diffusion sheet 90 can quickly absorb a large amount of urine when the urine is quickly discharged. The absorbent diffusion sheet 90 is desirably formed of a material that reversibly absorbs urine and is released. By being formed of a material that reversibly absorbs urine and is released, once the urine absorbed by the diffusion sheet is absorbed, it is slowly moved to the absorber, and the absorber is absorbed. On the other hand, the absorbing member 51 is formed of a material which is irreversibly absorbed into the urine and which is not easily released by the absorbed urine, or is preferably contained. Further, the absorbing member 51 is preferably formed of a material having a large absorption capacity, and the absorption capacity of the absorbing diffusion sheet 90 is preferably smaller than the absorbing capacity of the absorbing member 51. As such a material, a nonwoven fabric such as a hot air non-woven fabric having a single layer or a plurality of layers can be exemplified, and these can be used as the absorption diffusion sheet 90. Examples of the fiber forming the nonwoven fabric include polypropylene (PP) single fiber, polyethylene (PE)/polyethylene terephthalate (PET), PP/PE core sheath, or a side-by-side composite fiber. One type of these fibers may be used singly or in combination. These fibers or non-woven fabrics are rendered hydrophilic by applying a hydrophilic oil agent to the surface or by mixing a hydrophilic agent or the like.
吸收擴散薄片90是使用熱熔型接著劑等的接著劑與頂面薄片60及吸收體50接著。接著劑是藉由螺旋塗布、淋塗等塗布在吸收擴散薄片90、頂面薄片60或吸收體 50。 The absorption diffusion sheet 90 is adhered to the top sheet 60 and the absorber 50 using an adhesive such as a hot melt type adhesive. The adhesive is applied to the absorption diffusion sheet 90, the top sheet 60 or the absorber by spiral coating, shower coating or the like. 50.
以下，說明本發明的前述實施形態的作用效果。在頂面薄片上排尿後，因為溝部的基重低，所以每單位面積的纖維根數變少，阻礙液體透過的情況少，可使尿迅速往吸收體側移行。再者，藉由與男女不同被配置的吸收擴散薄片組合，在男女各自不同的位置被排泄的尿可更進一步迅速朝吸收體移行。此時，在產品腹側端部域有效賦予胯摺邊緊貼力與腰部帶片的束緊力，減低吸收擴散薄片與肌膚的隙間，而可使尿有效果地朝吸收體移行。根據本發明，排尿位置及吸收位置不同的男子與女子的睡姿等的尿在尿布表面流動時候的尿吸收提昇，尿漏減少。 Hereinafter, the effects of the above-described embodiments of the present invention will be described. After urinating on the top sheet, since the basis weight of the groove portion is low, the number of fibers per unit area is reduced, and the amount of liquid permeation is inhibited, so that the urine can be quickly moved toward the absorber side. Further, by combining the absorption diffusion sheets arranged differently from men and women, urine excreted at different positions of men and women can be further moved toward the absorbent body more quickly. At this time, in the ventral end region of the product, the tightening force of the crease and the tightening force of the waist strip are effectively imparted, and the gap between the absorbing and absorbing sheet and the skin is reduced, and the urine can be effectively moved toward the absorber. According to the present invention, the urine absorption of the urine such as the sleeping position of the man and the woman in the sleeping position and the absorption position is increased when the urine is flowing on the surface of the diaper, and the urine leakage is reduced.
吸收擴散薄片90理想是有著色。將吸收擴散薄片90著色成白色以外的顏色時，頂面薄片60等的用後即棄式紙尿布1的吸收擴散薄片90以外的構件理想是白色。藉此，可確實強調頂面薄片60中的設有吸收擴散薄片90的區域的頂面薄片60的肌膚抵接面的脊部61與溝部62。而且，對使用者可馬上傳達用後即棄式紙尿布1的頂面薄片60的表面被強化的功能的存在。又，由於在用後即棄式紙尿布1可賦予條狀的模様，所以可將用後即棄式紙尿布1做成造型優者。又，用後即棄式紙尿布1的使用後，頂面薄片60的脊部61比透過吸收擴散薄片90看得見的溝部62相比白，而看起來立體。因此，可讓使用者認識直接接觸穿用者的肌膚的部分白色且髒污少，可給予使用者清潔感高的印象。 The absorption diffusion sheet 90 is desirably colored. When the absorption diffusion sheet 90 is colored to a color other than white, the member other than the absorption diffusion sheet 90 of the disposable disposable diaper 1 such as the top sheet 60 is preferably white. Thereby, the ridge portion 61 and the groove portion 62 of the skin contact surface of the top sheet 60 in the region of the top sheet 60 where the diffusion sheet 90 is absorbed can be surely emphasized. Moreover, the user can immediately convey the function of strengthening the surface of the top sheet 60 of the disposable disposable diaper 1. Further, since the disposable disposable diaper 1 can be provided with a strip-shaped mold after use, the disposable disposable diaper 1 can be made into a good shape. Further, after the disposable disposable diaper 1 is used, the ridge portion 61 of the top sheet 60 is whiter than the groove portion 62 which is seen through the absorbing diffusion sheet 90, and looks three-dimensional. Therefore, the user can recognize that the part directly contacting the wearer's skin is white and less dirty, and gives the user an impression of high cleanliness.
又，藉由吸收擴散薄片90設置在吸收體50的面方向的區域的一部分的區域，所以藉由在用後即棄式紙尿布1的吸收層等的區域設置吸收擴散薄片90，使用者可容易認識吸收層等的區域。 Further, since the absorption diffusion sheet 90 is provided in a region of a portion of the surface of the absorber 50 in the surface direction, the user can provide the absorption diffusion sheet 90 in the region of the absorbent layer of the disposable disposable diaper 1 or the like. It is easy to recognize areas such as the absorption layer.
再者，設有吸收擴散薄片90的面方向的區域，藉由在男子用的用後即棄式紙尿布與女子用的用後即棄式紙尿布的不同配置，可容易在男子用的用後即棄式紙尿布與女子用的用後即棄式紙尿布認識不同的吸收層。藉此，被著色之吸收擴散薄片90適切地存在於穿用者的排尿點附近，藉由可容易認識在尿布的排尿點附近具有脊部與溝部，使用者可有效果地認識尿布的吸收功能提昇的情況。 Further, the area in which the surface of the diffusion sheet 90 is absorbed can be easily used for men by the different arrangement of the disposable disposable diaper for men and the disposable disposable diaper for women. The disposable disposable diaper and the disposable disposable diaper for women recognize different absorbent layers. Thereby, the colored absorption and diffusion sheet 90 is appropriately present in the vicinity of the wearer's urination point, and it is easy to recognize that there are ridges and grooves near the urination point of the diaper, and the user can effectively recognize the diaper absorption function. The situation of promotion.
