The elastic wrinkle member for the leg gathers is formed by the surface sheet 2 (the inner hydrophilic sheet 71). And the back sheet 3 is clamped and fixed. Further, by the contraction of the elastically stretchable member 10a, the leg gathers are formed in the lower portion C of the diaper 1. In the left and right side portions in the longitudinal direction (Y direction) of the diaper 1A, the sheets for forming a sheet for stereoscopic protection are disposed so as to cover the side portions of the surface sheet 2, respectively. Each of the three-dimensional protective forming sheets is fixed to the surface sheet 2 in a specific width region of the side portions in the longitudinal direction (γ direction) and the side portions in the width direction (X direction), and is oriented in the width direction ( The inner side of the X direction is in a free state. The side portion of the sheet for forming a three-dimensional protective sheet on the inner side in the width direction (χ direction), that is, the side portion near the center line CL has a three-dimensional anti-147153.doc 201039803 elastic member for protection forming 1Ia, and when worn, borrows (four) elasticity (4) Force of the member, the three-dimensional protection is formed by the free state portion inside the width direction (χ direction) of the sheet, and the three-dimensional pleats are formed on the skin contact surface side of the wearer in the diaper. The material for forming the disposable diaper μ of the first embodiment will be described. As the hydrophilic sheet 7, specifically, the surface sheet 2 (the inner hydrophilic sheet 71) and the outer hydrophilic sheet 72', a sheet material having hydrophilicity and absorbing moisture can be used. Here, 'the so-called "sheet material" refers to the state in which the fibers are not entangled in the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ For example, weaving. Further, the term "hydrophilic" includes both of the following: the fiber itself absorbs and retains moisture; and the person who absorbs and retains moisture by the space between the fibers. Examples thereof include a sheet of hydrophilic fibers and a sheet obtained by hydrophilizing a hydrophobic fiber with an oil or the like. Specifically, a non-woven fabric (for example, a spunlace nonwoven fabric) containing hydrophilic fibers such as cotton, yaki, or pulp may be suitably used; or a non-woven fabric containing hydrophobic fibers such as polyethylene fibers or polypropylene fibers may be hydrophilic by an oil agent or the like. The treatment is obtained. The top sheet 2 (the inner hydrophilic sheet and the outer sheet 72 are either sheets containing hydrophilic fibers or sheets obtained by hydrophilizing hydrophobic fibers), The combination is not limited, but when worn for a long period of time in a state of excessive sweating, since the liquid retention of the sheet itself is low, it is preferable to maintain the dry feeling of the skin side for a longer period of time. 5 The surface sheet 2 (the inner hydrophilic sheet 71) is a sheet obtained by hydrophilizing a water-repellent fiber of the melon. The basis weight of the hydrophilic sheet 7 is determined in consideration of the water absorption capacity and the like. For example, 147153. Doc -10- 201039803 When a hydrophilic fiber sheet is used as the hydrophilic sheet 7, the basis weight of the surface sheet 2 (the two-side hydrophilic sheet 71) is preferably 1 〇 to (10) g 〜 2, more preferably \When using a sheet of hydrophilic fiber, the outer hydrophilic sheet, the basis weight of 72 is preferably 1〇~8〇2, more preferably (4) g/mz. / Especially softness, flexibility by waist The contraction of the member 8 can easily form fine wrinkles, and reduce the wear to the wearer when in contact with the skin. Discomfort

The inner hydrophilic sheet 71 and the outer hydrophilic sheet are preferred from the viewpoint that the sweat accumulated in the gap between the fibers and the fibers is transferred to the outer hydrophilic sheet 72 by the expansion and contraction of the wrinkles. Compared with the material 72, it is easier to compress and deform, and it is easy to compress and deform. It is a sheet which is extremely easy to compress and compress in the thickness direction. By capillary force, sweat is quickly transferred from the skin contact side to the side of the contact surface _ 栗 too % 士月 ". It is preferred that the outer hydrophilic sheet 72 has a higher density than the inner hydrophilic sheet 71. When a sheet of hydrophilic fibers is used as the hydrophilic sheet 7, the density of the outer hydrophilic sheet is preferably 2 gw, more preferably 0 Å 2 g/cm3. When the hydrophilic sheet is used, the basis weight of the surface sheet 2 (the inner hydrophilic sheet 71) is preferably 〇.01 〇.2g/cm3, more preferably 0.02 〜0.1 g/ Cm3. ^The sweat that is transferred to the face of the skin is not reversed, and from the viewpoint of the outer hydrophilic 72 & body fluid, the outer hydrophilic sheet 72 is preferably the inner hydrophilic sheet 7_tt, which uses higher evapotranspiration. The bulk is measured by the following method for measuring the liquid evapotranspiration. ', ', <Method for measuring liquid evapotranspiration> 147153.doc 201039803 Spraying 0.2 g of distilled water on an acrylic plate. A sample of each of the inner hydrophilic sheet 71 and the outer hydrophilic sheet 72 of the loo mmxl00 mm square is placed on the steamed water of the jet, and is used at a constant temperature of 20 ° C and a humidity of 65 ° / RH. The change in weight is used to determine the amount of evapotranspiration of the steaming water. The amount of distilled water after 10 minutes (the weight of the sample containing distilled water after 1 minute - the original weight of the sample) is divided by the initial distilled water 2 illusion, the ratio is taken as the liquid The value of the evapotranspiration. The measured value is the average value of n = 3. As the back sheet 3, the absorber 4, and the sheet U for forming a pair of three-dimensional protection sheets, the corpse is usually used for disposable diapers. If you are an absorbent item, you can For example, as the back sheet 3, a resin sheet or a laminate of a resin film and a non-woven fabric can be used. As the absorber, a coating material such as a tlissue paper or a water-permeable non-woven fabric can be used. For example, a fiber assembly of a fiber material or a superabsorbent t compound is supported. As the sheet for forming a three-dimensional protective sheet, a stretchable film, a nonwoven fabric, a woven fabric, or a laminated sheet thereof can be used. === The member 8 for the formation of the leg gathers, the elastic member for forming the leg gathers, and the absorbent member 01 such as the elastic member Ua for the purpose of the disposable diaper spoon can be used without any particular limitation. For example, it can be used as a rubber, a polyaminocarbamic acid polymer, a polystyrene, an ethylene isoprene copolyester-ethylene, etc., a knee-based ethylene-polybutylene diene copolymer, a propylene acetamidine copolymer. A stretchable material such as a copolymer, etc. As an absorbent article such as a diaper which forms the fastening tape 9, it is listed as a fishing net (4), and it can be used as a "restricted use". For example, make agic -Tape (registered trademark) (Kuraray 147153.doc 201039803 (manufactured by KUraray) Co., Ltd.), r Quickl〇n (registered trademark) (manufactured by γκκ), "Magicl〇th (registered trademark)" (Kaneb〇BeU T〇uch), etc. Public components, etc. As the dry belt, a matte material having a surface structure capable of being fastened to the engaging projection of the fishing surface material is used, and as such a matte material, the hook surface can be fixed by pressing the hook surface material without any particular limitation. Material. For example, a mother member such as the above-described various known mechanical fishing surfaces and hook-and-plier fasteners can be used. Further, 0 may be a material which can be directly engaged with the engaging projection of the hook surface material, for example, a non-woven fabric having a fastening property, and constitutes the outer surface of the abdominal portion B (the non-skin contact surface of the back sheet 3). Next, the effect of the use of the diaper 1A of the embodiment of the present invention described above will be described. As shown in Fig. 1 and Fig. 2, the diaper 1A has a hydrophilic sheet 7 on the skin contact surface of the waist flaps 6a, 6b which are prone to eczema, lice, rashes, etc. (the inner hydrophilic sheet forming the skin contact surface) The material 71 and the outer hydrophilic sheet 72) disposed on the non-skin contact surface side of the inner hydrophilic sheet coffin 71 can transfer the perspiration of the wearer to the inner hydrophilic sheet 71. As shown in FIG. ,, the diaper 1A is formed with wrinkles by the waist elastic member 8 at the waist flaps 6a, and is often stretched and contracted by the wearer's breathing or walking motion, and is easily transferred to the inner side by the expansion and contraction. The sweat of the sheet 71 is transferred to the outer hydrophilic sheet 72. The diaper 1 A of the outer side of the hydrophilic sheet 72 is more diffusible than the inner hydrophilic sheet 7}, so that the hydrophilicity can be transferred to the outer side. The sweat of the sheet 72 spread rapidly. As a result, it is not easy to cause sweat to stay on the inner hydrophilic sheet 71 forming the skin contact surface of the waist flap, and the inner hydrophilic sheet 147153.doc 13 201039803 material 71 is not easily wetted, thereby preventing eczema. , scorpion, rash, etc. Further, since the inner hydrophilic sheet 7 1 and the outer hydrophilic sheet 72 of the diaper 1A are both sheets, the distance between the constituent fibers is not easily caused by the stretching of the wrinkles caused by the breathing or walking movement of the wearer. When the change occurs, the transfer property of the sweat from the inner hydrophilic sheet 71 to the outer hydrophilic sheet 72 is not easily lowered, so that the effect of preventing the occurrence of eczema, lice, macules, and the like can be maintained. Further, as shown in Fig. 3, the diaper 1At, the two outer hydrophilic sheets 72, and the cross-sectional and quasi-uniform diapers 1A are aligned in the direction of visibility (X direction), so that the liquid is more diffusible. The sweat transferred to the outer hydrophilic sheet 72 is diffused more rapidly. As a result, it is difficult to prevent the sweat from staying on the inner hydrophilic sheet 71 forming the skin contact surface of the waist flap 6, and the inner hydrophilic sheet 7i is not easily wetted, thereby preventing eczema and lice' rash.
