[Prior art] Between the liquid-permeable top sheet and the liquid-absorptive suction sheet, a disposable diaper having a bottom sheet to ensure the holding space of excrement has been widely known. However, in these diapers, the wearer's body pressure is often added during wearing, and the backsheet is often damaged, and the desired holding space cannot be secured. In addition, because the disposable diapers are generally stacked and most of the packages are sold on the ground, and considerable pressure is added to the packaging, the underlying film is crushed for other reasons. As a result, it is difficult to sufficiently absorb and maintain soft stools with high fluidity, and it is easy to cause leakage of soft stools. The mouth is different from these conventional techniques' and proposes a disposable diaper in which banks are formed on both sides of the absorbent body to prevent leakage of stool. However, these diapers are those who increase the height of the dike to block the stool, and are not those who absorb the stool between the dike and the dike to prevent it from leaking out. [Summary of the Invention] Therefore, the object of the present invention is to provide a disposable diaper, which has a low viscosity, such as soft stools, which is excellent in absorption and maintenance of the world, and can prevent leakage. " In order to achieve the above object, the present invention provides a disposable diaper, which is a liquid-permeable top sheet, a liquid-impermeable back sheet, and a two-door, liquid-retaining absorber; 273 83867 200402284 The absorbent includes: a lower absorbent layer containing a superabsorbent polymer; an anti-compression layer disposed on both sides of the upper surface of the lower absorbent layer; and an upper absorbent layer disposed on a pair of the absorbent layers. The non-woven fabric between the compression-resistant layers is the main body; the KES compression ratio of the compression-resistant layer is formed lower than the KES compression ratio of the upper absorption layer. [Embodiment] The present invention will be described below with reference to the drawings according to a preferred embodiment. FIG. 1 is a plan view showing a disposable diaper according to a first embodiment of the present invention as viewed from the top sheet side, and FIG. 2 is a cross-sectional view showing a line π-π of FIG. 1. As shown in FIG. 1 and FIG. 2, the disposable diaper 1 of this embodiment type is a top sheet having liquid permeability 2, a back sheet 3 having liquid impermeability, and a back sheet 3 between the top sheet 2 and the back sheet 3. The liquid-retaining absorber 4 is constituted. The top sheet 2 and the back sheet ^ are the areas corresponding to the crotch region of the diaper 1 to be bent to form a sander-shaped middle timer. On the one hand, the absorber 4 is formed in a rectangular shape. The absorbent body 4 is held and fixed by the top sheet 2 and the back sheet 3. The top sheet 2 and the back sheet 3 extending outward from the front and back of the absorbent body 4 form the back and ventral waist sheet portions 5, 5 '. In addition, the top sheet 2 and the back sheet 3 'which extend out from the sides from the left and right edges of the absorbent body' are formed to the leg sheet portions 6, 6. Three leg-shaped elastic stretchable members 6 & 63 are arranged on the leg pieces 6 and 6, and the elastic stretchable members are fixed by the top sheet 2 and the back sheet 3. Further, the elastically stretchable member 6a contracts to form a leg gather. 83867 200402284 and the front and rear ends are fixed to the top sheet 2 while the inner side is in a free state. Further, elastically stretchable members 7a, 7a are fixed to the side edge of the inner portion along its longitudinal direction. Furthermore, by shrinking the elastically stretchable member, the aforementioned inner portion of the three-dimensional pleated palm-forming sheet 7 stands up to form a three-dimensional frame on the skin-contacting side of the wearer of the diaper !. A pair of stoppers 8 formed by tape fixings and the like are installed on the both sides of the back side waist portion 5 in the wide direction, and on the back side waist portion 5 and the back plate 3 ' Attach an adhesive attachment (not shown) formed by a rectangular positioning tape. Further, when the disposable diaper of the embodiment is worn, the stoppers 8, 8 are fixed to the adhesive attachment. As the back sheet 3 and the three-dimensional gathers forming sheet 7 constituting the diaper 1, and the elastic stretchable members 6a and 7a, those generally used in this technical field can be appropriately used. For example, as the back sheet 3, a film of a thermoplastic resin, or a composite sheet of a film of a thermoplastic resin and a nonwoven fabric can be used. As described later, the thermoplastic resin film may have moisture permeability. The three-dimensional pleated palm-forming sheet 7 can be made of various nonwoven fabrics such as a spun-bonded nonwoven fabric, an air-through nonwoven fabric, a spun-bonded / melt-blown / spun-bonded nonwoven fabric (SMS, SMMS). Elastic expansion and contraction members can be used, 7a, can use polyurethane rubber yarn and so on. Details of the top sheet 2 and the absorbent body 4 will be described later. As shown in FIG. 2, the diaper 1 of the present application type has an absorbent body 4 including a lower absorbent layer 10, an anti-compression layer 11, and an upper absorbent layer 12; the lower absorbent layer 10 ′ contains a highly absorbent polymer. The anti-compression layer 丨 丨 is disposed on both sides of the upper surface of the lower absorption layer 丨 0; the upper absorption layer ^ is mainly composed of a non-woven fabric disposed between the anti-compression layers 11. 83867 200402284 The lower absorbent layer is a vertically long rectangular shape, and its length is generally arranged to be consistent with the length direction of the diaper. The lower absorbent layer 10 is composed of a fibrous aggregate formed by absorbing a paper 10b such as tissue paper with a superabsorbent polymer particle and a paper polymer fiber as a royal body. The anti-compression layer u is narrower than the width of the lower absorbent layer and is approximately the same as the length of the lower absorbent layer 10. The long absorbent layer is rectangular in shape and extends in the longitudinal direction of the diaper i. The anti-compression layer n 'has a certain thickness across its length. The anti-compression layer u is arranged on the upper surface of the lower absorption layer 10 approximately at its side edge and the side edge of the lower absorption layer 10 approximately. The upper absorption js! 9, 尨 & π, and the receiving layer 12 are approximately the same shape as the lower absorption layer 10, and cover the upper surface of the anti-compression layer 11 and the lower absorption layer 10. The anti-compression layer? Has a KEsm shrinkage ratio lower than that of the upper absorption layer 12. The KES compression rate is stipulated in the Japan Institute of Fiber Machinery, a corporation of Osaka Prefecture, issued by the Quality and Style Measurement and Standardization Research Committee (July 1G, 1_1). Kawabata Toshio's work "Standardization and Evaluation of the F-Quantity Style Analysis (Second Board) "-Book, which is about the physical properties of the compression characteristics of cloth. The KES compression ratio used for the compression characteristics of cloth is also described in, for example, Japanese Patent No. 2514294. The specific method of measuring the KES compression ratio will be described later. The absorbent body 4 of the diaper 1 according to the present embodiment has the above structure, thereby improving the absorption and retention of excrement, particularly the soft stool of the low-viscosity body. Specifically, since the upper absorbent layer 12 is composed of a non-woven fabric as a main body and is bulky, as described above, the wearer's body pressure is applied to the absorbent body 4 when the diaper is worn, or the diaper is It is easy to be crushed after packaging, but by compressing the anti-compression layer u on both sides of the upper absorption layer 12, the crushing of the upper absorption layer a can be prevented. As a result, the upper absorptive layer 12 can maintain its swelling during wearing of the diaper 丨 2S2 83867 200402284 loose ', but it can hold the space to absorb soft stools. This improves the absorption and retention of soft stools. In particular, as shown in FIG. 2, after the upper absorbent layer 12 covers the upper surface of the anti-compression layer 11, even if the wearer's body pressure is applied to the absorbent body 4 or is packed to compress the upper absorbent layer 12 ′, the upper absorbent layer can be surely guaranteed. The thickness of 12 reaches the thickness of the anti-compression layer u. By maintaining the bulkiness of the upper absorbent layer 12, in addition to the above effects', the next effect can also be exhibited. That is, the absorbent body 4 can maintain a soft state even when the body pressure of the user is strong or is packed, and a comfortable wearing feeling can be obtained. In addition, the absorbent body 4 is more rigid than the central part in the wide direction. Because the side part is relatively stiff, when the diaper is worn, the cross-sectional shape of the absorbent body 4 in the wide direction is changed to a slightly inverse ω shape. The diaper 1 can fit around the feet of the wearer. The compression-resistant layer 11 is preferably made of a material that can resist body pressure and packaging pressure of a wearer and is not compressed. For example, the compression-resistant layer U may be composed of a fibrous body of paper fibers, a structure of thermoplastic fibers, a foam made of synthetic resin, or the like. In particular, from the viewpoint that the KES compression ratio of the anti-compression layer 11 is extremely lower than the KES compression ratio of the upper absorption layer 2, the anti-compression layer is composed of a paper-polymer fiber laminate, porous nonwoven fabric, and foam. good.柷 The KES compression rate of the compression layer 11 itself is 20 ~ 60%, especially 25 ~ 55 〇 / 〇, it is better to effectively prevent the compression of the anti-compression layer i 丨. The anti-compression layer 11 has a thickness. From the viewpoint of ensuring the minimum thickness of the upper absorbent layer 12 when the wearer's body pressure is applied to the absorbent body 4 and the upper absorbent layer 12 is compressed, the thickness is 0.7 at a load of 50 gf / cm2. Above, especially above 1 mm is preferred. The upper limit value of the thickness of the anti-compression layer is determined from the viewpoint of the fit of the diaper when worn, the comfort during wearing, and the capacity of the diaper 83867 -10- 200402284, which is easy to fold into three folds, etc., with 5 mm Below, especially below 4 mm. The width of each anti-compression layer 11 is 5 to 40 mm, especially 10 to 30 mm. It is preferable to ensure sufficient absorption area for soft stools and effectively prevent compression. For the same reason, the ratio of the width of each anti-compression layer to the width of the absorbent body 4 (the width of the lower absorption layer 10 and the upper absorption layer 12 in this embodiment) is 5 to 35%, especially 1 〇 ~ 30% is better. Furthermore, for the same reason, the distance between the inner side edges of each anti-compression layer 11 is preferably 30 to 90% ', particularly 40 to 80% of the width of the absorbent body 4. In addition, the anti-compression layer j ^, although the weight of the paper is 75 ~ 700g / m2, especially 150 ~ 600g / m2, especially 200 ~ 500g / m2, the absorption area for soft stools is fully ensured and effectively prevented The compression point is better. The length of the anti-compression layer 11 is almost the same as the length of the absorbent body 4 (= the length of the lower absorption layer 10 and the upper absorption layer 12). However, if the length of the anti-shrink layer 11 is more than 25% of the length of the absorbent body 4, especially two = or more, the compression of the upper absorbent layer 12 can be fully prevented.

The fineness of the fibers constituting the non-woven fabric is 2 15 dtex, especially 3 to 10 dtex, especially 4 to 10 cores. It is better to maintain the absorption of soft feces and improve the permeability. The upper absorption layer 12 has a KES compression ratio larger than that of the anti-compression layer 11. The upper absorption layer 12 has a KES compression ratio of 40 to 80%, particularly 45 to 75%, and it is preferable to maintain the soft stool absorption space and the flexibility of the absorbent body. In addition, the compression rate of the anti-compression layer litKES is 0.4 times to 0.85 times smaller than the other compression rate of the upper absorbing layer 12, especially 0.5 to 0.8 times, which effectively prevents compression of the upper absorbing layer 12. Better. Although the weight of the upper absorbent layer 12 'is 15 to 200 g / m2, especially 25 to 150 g / m2', and particularly 30 to 100 g / m2, from the viewpoint of maintenance and economical efficiency of the absorbent layer. Look better. In addition, the thickness of the upper absorbing layer 12 under a load of 0.05 gf / cm2 is 0.75 to 5 mm, particularly 0.75 to 4 mm, and the thickness under a load of 50 gf / cm2 is 0.25 to 2.5 mm, especially 0.3 to 2 mm. It is preferable to maintain a soft absorbing space and soften the absorbent body. In the present embodiment, the upper absorbing layer 12 is implemented, and the length is approximately the same as the length of the absorbing body 4 (the length of the second lower absorbing layer ί). However, to the right of the length of the upper absorbing layer 12 is 25% or more of the length of the absorbent body 4, particularly 33% or more, sufficient soft stool absorption and retention can be achieved. When the length of the upper absorbent layer 12 is shorter than the length of the absorbent body 4, the upper absorbent layer 2 is arranged from the area corresponding to the excretion part of the wearer of the absorbent body 4 to the area corresponding to the back side part. It is better to fully absorb and maintain. 83867 -12- 200402284 The top sheet 2 covering the upper surface of the absorbent body 4 can be transmitted softly quickly. Furthermore, it is preferable that the top sheet 2 has a plurality of openings h which are formed regularly by softening and softening. The opening h-/ is mm, especially 15 to 4 mm. The point of ensuring rapid passage of soft stools is prevented and prevented-but the point of absorbed soft stools returning is preferred. For the same reason, each opening is 4 ~ 20 mm, especially ㈣_ is better. As the non-woven fabric constituting the top sheet 2, a hydrophilic air-permeable non-woven fabric M 1 yarn-bonded non-woven fabric, a non-woven yarn non-woven fabric, and the like can be used. Among these non-woven fabrics, it is preferable to use a ventilated non-woven fabric and a non-woven non-woven fabric from the point that the soft stool passes through quickly. The fineness of the fibers constituting the non-woven fabric is from 0.5 to ⑸㈣, especially from 1 to the point where the softness and touch of the skin are better. The woven fabric may be composed of two kinds of fibers having different finenesses. At this time, the non-woven fabric is used as the upper layer, that is, the fiber of the layer facing the wearer's side. Use 0.5 to 5.5 dtex, especially as the lower layer, that is, the layer facing the lower side of the absorber. For fibers that use 2 to 10 dtex, especially 4 to 8 dtex, it is better to maintain the touch of the non-woven skin and improve the absorbency of soft stools. In this embodiment, the KES compression ratio for forming the upper absorption layer 12 at a lower compression ratio than that of the top sheet 2 just described is better. This means that the top sheet 2 is softer than the upper absorbent layer 2. Thereby, the wearing feeling of a diaper is better. In addition, the upper absorbent layer 12 is relatively harder to compress than the top sheet 2. Therefore, even when an unexpected body pressure is applied, the upper absorbent layer 12 is difficult to be compressed, which can ensure a soft stool retention effect. For the same reason, the upper KES compression rate of the top suction 83867 -13- 200402284 and the closing layer 12 is smaller than the KES compression rate of the top sheet 2 by 33 times to 0.85 times, and particularly preferably 0.4 times to 0.8 times. . The compression rate of the top sheet 2 is 60 to 95%, especially 70 to 90%. From the viewpoint of giving the wearer a soft feeling, the point that the diaper 1 has a good feeling of wearing is preferable. Although the top sheet 2 has a paper weight of 15 to 80 g / m2, and particularly 20 to 60 g / m2, it is preferable from the viewpoint of softness of permeability and quality style. In addition, the thickness of the top sheet 2 under a load of 0.5 gf / cm2 is 0.8 to 3 mm, particularly 0.8 to 2 6 mm, and the thickness under a load of 50 gf / cm 2 is 2 mm, particularly 0. 2 to 10, preferably from the point of softness. The absorbent body 4 of the diaper 1 of this embodiment is appropriately manufactured by the method shown in FIG. First, a hard paper made of thin paper or the like is drawn from the original sheet 21. The extracted hard paper 20 passes through the lower part of the first fibrillator 22. The first fibrillator 22 is used to produce a fibrous body 24 having a rectangular shape after crushing the pulp sheet 23 supplied thereto and forming a fibrous state. Although not shown in the figure, particles of a superabsorbent polymer are also supplied to the first fibrillator 22, and the particles of the superabsorbent compound are uniformly mixed with the pulp broken into a fibrous state. The fibrous body 24 having a rectangular shape is placed on the central portion of the hard paper 20 in the width direction. This state is shown in FIG. 3 (a). The fibrous body 24 is intermittently placed on a hard paper 20. The hard paper 20 on which the fibrous body 24 is placed is introduced into a well-known folding device 2 5 'so that both side portions thereof are folded into the upper side of the fibrous body 24. The fibrous body 24 is thereby covered with the hard paper 20. As a result, a lower absorption layer formed of a continuous body is formed. This state is shown in FIG. 3 (b). The continuum of the lower absorbent layer formed in this way has its upper and lower surfaces reversed, and then passes through the lower portion of the second fiberizer 25. The second fibrillator 25 is used after being crushed and supplied to 83867 -14- 200402284, and the pulp sheet 26 is in a fibrous state, in order to manufacture an elongated fibrous body 27. Two thin fibrous bodies 27 are formed in the younger fibrillator 2 5. Each of the fiber bodies 27 is manufactured intermittently, and is placed on the continuous body of the lower absorption layer, respectively. The placement positions of the fibrous bodies 27 are located on both sides of the fibrous bodies 24 of the continuous body of the lower absorption layer. This bear is shown as (c) in FIG. 3. Next, a continuous sheet 29 of the upper absorbent layer, which is extracted from the original sheet 28 provided downstream of the second fibrillator 25, is formed to cover the continuous body of the absorbent layer under the fibrous body 27. The sheet 29 has the same width as the continuum of the lower absorbent layer. This state is shown in FIG. 3 (d). Thereby, a continuous body including an absorbent body including a lower absorbent layer, an upper absorbent layer, and an anti-compression layer is manufactured. The continuum is held at a certain position in the subsequent step, and is cut in a wide direction to form each absorbent body. Next, a second embodiment of the present invention will be described with reference to Fig. 4. Regarding the present embodiment, only points that are different from the first embodiment will be explained ', and in particular, points that are not explained will be appropriately applied to the detailed description of the first embodiment. In Fig. 4, the same components as those in Figs. 1 and 2 are assigned the same reference numerals. Fig. 4 is a view corresponding to Fig. 2 of the i-th embodiment. The diaper of this embodiment differs from the diaper of the first embodiment only in that the upper absorbent layer 12 is disposed between an anti-compression layer and the upper absorbent layer 12 does not cover the upper surface of the anti-compression layer 11. point. Even in this embodiment, as in the first embodiment, by arranging the anti-compression layers 11 on both sides of the upper absorbent layer 12, it is possible to prevent the upper absorbent layer 12 from being crushed and improve the absorption and retention of soft stools. However, only the upper absorbing layer 12 does not cover the upper part of the anti-compression layer 11, and the effect of preventing crushing of the upper 83867 -15-200402284 absorbing layer 12 is smaller than that of the first embodiment. The KES compression ratio of the present invention is measured by the next method. The KES-FB3 compression tester made by kato-teku was used for the set-up. This tester was used to measure a compression area of 2 cm2 and a thickness τ under a load of 0.5 gf / cm2 of the sample. Next, the sample was compressed at a pressure rate of 20 μm / sec. As the compression load increases gradually. Compression is performed until the load reaches 50 gf / cm2. Then, the thickness Tm under a load of 50 gf / cm2 was measured. Divide the thickness by 0.5 gf / cm2. Divide the thickness by 0.5 gf / cm. D subtract the thickness of the household under 50 gf / cm.

For example, in the first embodiment, the entire upper area of the tax compression layer 1 is covered by the upper absorbing layer 12, but instead of this, at least a part of the upper surface of the anti-compression layer may be covered. In addition, in each of the aforementioned embodiments, although the anti-compression layer 11 extends continuously in the longitudinal direction of the sheet, instead of making the anti-compression layer discontinuous, the front-end portion of the anti-compression layer 11 and / or At the back end, two anti-compression layers can be connected. The lower absorptive layer 10 may be not only a vertical moment, a timer, or a T-shape. The present invention will be explained in more detail by way of example for His Majesty. However, the scope of the present invention is not limited to these embodiments. Examples 1 to 8 and Comparative Examples 1 to 3 (1) Production of Top Sheet This table shows these KES pressures. Table 1 shows various types of top sheet shrinkage. 83867 16-200402284 (2) Manufacturing of upper absorbing layer Various kinds of upper absorbing layers of the types shown in Table 1 were manufactured. The table shows these KES compression ratios. (3) Manufacture of anti-compression layer The pulp fibers were laminated into 200g / m2, 300g / m2, and 400g / m2, respectively, and this was cut into a width of 25 mm and a length of 285 mm to obtain a compression-resistant layer. Each anti-compression layer is placed on the lower absorbent body such that these outer side edges overlap the lower edge of the lower absorption layer, so that the distance between the inner side edges of the anti-compression layer becomes 40 mm. Table 1 shows the KES compression ratio of the anti-compression layer. (4) Manufacture of lower absorbent layer A fibrous body having a weight of 478 g / m2 and a paper containing 63% by weight of pulp fibers and 37% by weight of superabsorbent polymer was cut into a width of 90 mm and a length of 285 mm. The rectangle is made of a thin paper with a weight of 16 g / m2, and the fiber body is wrapped to form a lower absorbent body. (5) Back sheet Use a moisture-permeable back sheet with a weight of 40g / m2. The components obtained in the above (1) to (5) were used in combination as shown in Table 2. For the adhesion of each member, a sample for performance evaluation was obtained using a hot-melt adhesive. Performance Evaluation For the evaluation samples obtained in the examples and comparative examples, the soft stool absorbency was evaluated by the following method. The results are shown in Table 2. Soft stool absorbency Test bench with beveled acrylic plate. The tilt angle of the acrylic plate is set appropriately (for example, 10 degrees). The angle is measured with an angle meter, and the slope error is ± ι 83867 -17- 200402284 degrees. In addition, the acrylic plate is leveled in a direction orthogonal to the oblique direction. Before the test, check whether the soft stools hang on the acrylic plate and whether they flow down in a straight line. If not, adjust the angle of the acrylic plate. Next, a sample for evaluation was placed on the acrylic plate. On the evaluation sample, 30 g of the sample was dropped from a glass tube having an inner diameter of 3 mm at a rate of 3 g / sec. At this time, the tip of the glass tube is changed from the dropping position of the evaluation sample to approximately the top. The dropping position of the evaluation sample is located 190 mm from the lower end portion of the evaluation sample toward the upper side, and is located at the center of the width direction of the evaluation sample. After dropping a certain amount of soft stool, measure the flow down distance and diffusion area, and observe whether there is leakage. ~ 3 samples of soft stool preparation were added in 1500 g of kurancm ^ PVA-based synthetic cleaning cream from Uehara Chemical Co., Ltd. in Tokyo, Japan, plus edible blue sold by Aizen, a Japanese company in Japan. No. 〇1§. In addition to the separation, change the water, adjust the viscosity to 25 ± rC to become 3〇 ± 3 mpa.

For this, 83867 -20- 200402284 The results shown in Tables 1 and 2 can be used, and the examples show that each example has excellent absorption and retention of soft stool samples, which can prevent leakage. Regarding this, in the comparative example without the anti-compression layer, the J head does not have a soft absorption and retention property of the sample, and the leakage caused by the liquid flow on the surface is poor. Also using the evaluation option of Example 1 to manufacture disposable diapers for newborns with the structure of the present example, the practical surnames and names were confirmed, and it was confirmed that watery stools (soft stools) were absorbed. <Thinking There are many, and the leakage rate of stool is reduced. As described in detail above, the person of the present invention also throws off a diaper-type diaper, which can effectively absorb and maintain low-viscosity excreta such as soft stools, and can effectively prevent its leakage. In addition, this ㊆ 明 (polishing dish diapers 'can maintain the soft t-state of the absorbent body, so you can get comfortable wearing 舒适. Furthermore, the wearable diapers' cross-sectional shape of the absorbent body in the width direction is easy to change. Forming a slightly inverted ω shape, the diaper can fit around the wearer's feet. The disposable diaper of the present invention is particularly suitable. The disposable diaper for neonates with a large number of human excretion times.
