[Prior art] Disposable diapers which have a bottom sheet to ensure the holding space of excrement between the top sheet of liquid lag and the absorbent body for liquid retention are widely known. However, in these diapers, the wearer's body pressure is often added during wearing, and the backsheet is often crushed, and the desired holding space cannot be secured. In addition, because disposable diapers are folded and sold together in a large number of packages, considerable pressure is also applied to the packaging, so the bottom sheet 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 soft stools to leak out. In contrast to this conventional technique, a disposable diaper is proposed in which an absorbent body is formed on both sides of the absorbent body to prevent it from leaking. However, these diapers are not the ones who know how to prevent them from absorbing diarrhea, and are not the ones who absorb the stool between the dike and the dike to prevent it from leaking out. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a disposable diaper which is excellent in absorption and retention of low-viscosity excreta such as soft stools and can prevent leakage thereof. 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 liquid-retaining absorbent body between the two sheets; 83867 1230052 The lower absorption layer contains a superabsorbent polymer; the anti-compression layer is disposed on both sides of the upper surface of the lower absorption layer; and the upper absorption layer is disposed between a pair of the compression-resistant layers. Non-woven fabric is the main body; the KES compression ratio of the anti-compression 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 the first embodiment of the present invention, the diaper holding diaper viewed from the top sheet side, and FIG. 2 is a cross-sectional view showing a π-π line of FIG. 1. IS) 1 1 ~~ m No, outer is 丄, attachment, liquid-permeable top sheet 2, liquid-impermeable back sheet 3, and liquid-retaining absorbent body 4 between the top sheet and the back sheet 3 Made up. The top sheet 2 and the back sheet 37. The area corresponding to the lower area of the diaper i is curved by f to form a thinner timer shape. On the one hand, the absorber 4 is formed in a rectangular shape. Moreover, the body 4 is held and fixed by the top sheet 2 and the back sheet 3. The top sheet 2 and the back sheet which extend to the outside from the front and back of the absorbent body 4 are waist sheet parts 5, 5 | on the back and ventral sides. In addition, the top sheet 2 and the back sheet 3 H / 6 are extended from the lateral sides from the left and right 1 edge portions of the absorbent plutonium. On the leg portions 6, 6 are arranged three linear elastic members: The elastic telescopic member 6a is fixed by the top sheet 2 and the back sheet 3—the members 6a and 6a, and the telescopic member 6a contracts to form a leg gather. Alas. The elasticity is on each of the left and right sides of the diaper 1, and there are three-dimensional pleats forming sheets 7 and 7 on top of the pen. Each three-dimensional inspection; = the side part is arranged 1 成 成 片 7 系 的 外 外 83867! 23〇0524 and front and rear ends Shao are fixed to any one of Ding g 'while its inside part is formed from &. In addition, elastic extension members 7a and 7a are fixed to the side edge of the inner side of the child. Moreover, by elongating the elongation percentage, the armor member 7a shrinks, and the aforementioned inner portion of the three-dimensional pleated mesh 7 is also opened 3'M I, which is pulled to the side of the wearer of the diaper 1 Form a three-dimensional pleated palm. The opposite face is the official girl one or two on the back waist part 5. The pair of stoppers 8, which are formed by mounting foot objects on both sides of the universal joint, are put together. North ^, force piece 8, and on the waist part 5 on the ventral side, the same piece 3 is pasted with a sticky attachment (not shown) formed by the rectangular shape of Ding Yi Temple. Also, it is worn. This punishment is implemented. Not only her type of complaints < disposable diapers, the stoppers 8 and 8 are fixed to the adhesive attachment. D is used as the back sheet 3 constituting the diaper 1 and the sheet for the formation of the limulus denier. 7. The elastic members 0a and 7a can be appropriately applied with a force ~, which is usually used in the technical field. For example, the back sheet 3 can be used to use a plastic resin film or a lamination. The film of thermoplastic resin and the blessing of non-woven fabrics, "Founkou mouthpiece. As described below, the film of thermoplastic resin can also be transparent. Three-dimensional pleated _ forming sheet 7, you can use each Non-woven fabrics, such as spun-bonded non-woven fabrics, ventilated non-woven fabrics, spun-bonded / bright melt blown / spun-bonded non-woven fabrics (SMS, SMMs). Elastic expansion and contraction members ^, ~, can be made of polyamine-made rubber yarn. The detailed description of 2 and absorber 4 will be described later. As shown in FIG. 2, the diaper of this embodiment is provided with a lower absorbent layer 10, a pair of 柷 compression layers 11, and an upper absorbent layer 12; The lower absorption layer 10 contains a superabsorbent polymer; the anti-compression layer 丨 丨 is disposed on both sides of the upper surface of the lower absorption layer 10; the upper absorption layer 12 is disposed in an anti-compression layer. The non-woven fabric between the layers U is the main body. 83867 1230052 The lower absorbent layer Η) is a long rectangular shape, and its length direction is arranged to be the same as that of the diaper 1. The lower absorbent layer 10 is made of absorbent paper such as tissue paper. ⑽It is composed of a fibrous material 10a formed mainly by a mixture of particles of superabsorbent polymer and paper fibers. The anti-compression layer u is narrower than the lower absorption layer 10 and is made to absorb the lower portion. Layer 10 is approximately the same length The long rectangular shape extends in the length direction of the diaper 丄. The anti-compression layer u has a certain thickness across its length. The side edge of the anti-compression layer u is approximately the same as the side edge of the lower absorbent layer 10. It is generally arranged on the upper surface of the lower absorption layer ο. The upper absorption layer 12 is approximately the same shape as the lower absorption layer 10 and covers the upper surfaces of the anti-compression layer 11 and the lower absorption layer 10. 柷 The compression layer 11 has a KES compression ratio It is formed at a lower compression rate than 12iKES of the upper absorbing layer. The KES compression rate is stipulated by the Japan Fiber Machinery Association, the Quality and Style Measurement and Standardization Research Committee of Osaka Prefecture, Japan (July 10, 1980) 'Kawabata Ji Xiong's book "Standardization and Analysis of Quality Style Evaluation (Second Board)" is about the physical properties of the compression characteristics of cloth. The KES compression ratio used for the compression characteristics of the cloth is also described in, for example, Japanese Patent No. N1414294. The specific method of measuring the KES compression ratio will be described later. The absorbent body 4 of the diaper 1 of the present embodiment has the above structure, thereby improving the absorption and retention of excrement, particularly the soft stool of the low-viscosity body. In detail, since the upper absorbent layer 12 is composed of a non-woven fabric as the main body and is bulky, the body pressure of the wearer is applied to the absorbent body 4 or the diaper cover during the wearing of the diaper 1. It is easy to be crushed after packaging, but by disposing the anti-compression layer 11 on both sides of the upper absorbent layer 12, the crush of the upper absorbent layer 12 can be prevented. As a result, the upper absorptive layer 12 can maintain its bulkiness during wearing of the diaper 1 83867 -9-1230052, and can maintain a space for absorbing soft stools. Thereby, the effect of absorption and retention of soft stool is promoted. 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 11. By maintaining the bulk of the upper absorbent layer 2, in addition to the above effects, a secondary effect can also be exerted. That is, the absorbent body 4 can maintain a soft shape even if the body pressure of the dental user is added or is packaged, so that the absorbent body 4 can be comfortably worn. In addition, the absorbent body 4 is more rigid than the central portion in the wide direction, so the lateral shape of the absorbent body 4 in the diaper when worn is easy to change into a slightly inverted Ω shape when the diaper is worn. 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 laminated layer 1 丨 can be composed of a structure of cut-to-length flat plastic fibers of pulp fibers, a foam made of synthetic resin, or the like. In particular, from the viewpoint of making the compression ratio of the anti-compression layer 丨 丨 very low compared to the KES compression ratio of the f5 absorbent layer 12, & pulp fiber = layer shirt, porous nonwoven fabric, foam, etc. constitute the anti-compression layer. 11 is better. [The KES compression rate of the plutonium layer 11 itself is 20 ~ 60%, especially 25 ~ 550 / 〇, it is better to effectively prevent the compression of the anti-compression layer. The contact compression layer 11 has a predetermined thickness. From the viewpoint of ensuring that the wearer's cylinder pressure is applied to the absorbent body 4 to compress the upper absorbent layer 12 when the upper absorbent layer 12 is compressed, the thickness is 0.7 mm at a load of 50 gf / cm2. In particular, it is preferably 疋 1 mm or more. The upper limit of the thickness of the anti-compression layer 丨 丨 is determined from the viewpoint of the fit of the diaper when worn, the comfort during use, and the capacity of the diaper 83867! 230052 It is preferably 5 minutes or less, especially 4 mm or less. 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 compression-resistant layer} 1 to the width of the absorbent body 4 (the width of the lower absorbent layer 10 and the upper absorbent layer 12 in this embodiment) is 5 to 3 5%, especially 10 to 30% is preferred. Furthermore, for the same reason, the distance between the inner side edges of each anti-compression layer 11 is preferably 30 to 90% of the width of the absorbent body 4, and more preferably 40 to 80%. In addition, the anti-compression layer u, although the weight of the paper is 75 ~ 700g / m2, especially 150 ~ 600g / m2, especially 200 ~ 500g / m2, the absorption area for soft stool is fully ensured and the compression is effectively prevented The point is better. The length of the compression-resistant layer U in this embodiment is approximately the same as the length of the absorber 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 25% of the length of the absorbent body 4, in particular, it is equal to or greater than 0, the compression of the upper absorbent layer 12 can be sufficiently prevented, and the anti-compression layer can be used. In the case where the length of 11 is shorter than the length of the absorbent body 4, the anti-compression layer u changes from the area corresponding to the excretory portion of the wearer to the area corresponding to the back side. Better. As described above, the upper absorbent layer 12 is mainly composed of a non-woven fabric. For example, only ST12 is made of nonwoven fabric, resin-bonded nonwoven fabric, porous, etc., made of nonwoven fabric, partially combined with thermoplastic fibers, composites of thermoplastic fibers and pulp fibers, and superabsorbent polymers. Non-woven fabrics, hot-rolled non-woven fabrics, spun bonded non-woven fabrics, etc. 83867 l23〇〇52 In these non-woven fabrics, from the point of view of the non-woven fabrics, it is better to use loose cloth and non-woven non-woven fabrics which can fully ensure the holding space of soft stools. No, I, especially 3 10 dt into non-fabric fibers ', its fineness is soft ... and especially 4 ~~' from the point of maintaining the absorption of the workshop & 咼 permeability is better. The KES compression ratio of the Shizhuang absorption layer 12 is higher than the MS compression ratio of the anti-compression layer 11. The KES compression ratio of the absorption layer 12 is ~ ⑽%, especially 45% to 75%. The softness of the body is preferred. In addition, the compression ratio of the anti-compression layered layer is 0.4 times to 0.85 times lower than the compression ratio of the upper absorption layer, especially 0.5 to 0.8 times, which effectively prevents the compression of the upper absorption layer 12 Better. Although the weight of the paper of Shangshao Absorptive Layer 12 is 15 ~ 200〇§ ~ 2, especially 25 ~ 150g / m2, especially 30 ~ 100g / m2, it is maintained by the absorption layer and economically. Viewpoints. 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, although the thickness under a load of 50 gf / cm2 is 0.25 to 2.5 mm, especially ο ″ ~ 2 mm, from the point that the absorption space of the soft stool can be maintained and the point that the absorbent body can be made soft. In this embodiment, the length of the upper absorption layer I2 is approximately the same as the length of the absorber 4 and the length of the lower absorption layer 10). However, if the length of the upper absorbing layer 12 is 25% or more, particularly 33% or more of the length of the absorbent body 4, soft stool can be sufficiently absorbed and held. When the length of the upper absorbent layer 12 is shorter than the length of the absorbent body 4, the upper absorbent layer 12 is arranged from the area corresponding to the excretory portion of the wearer of the absorbent body * to the area corresponding to the back side portion. It is better to fully absorb and maintain. -12- 83867 1230052 From the point of view of the burlesque covering the absorbent body 4, it is made of non-woven fabric. Compared with Γ :: the point where the soft stool passes through quickly and the soft stool passes through, the top sheet 2 advances more quickly and stands straight ... '”… It is also preferable to form a large number of openings. The openings η are eight and the position is 1 to 6 mm. The point of special penetration and the prevention of n' mm 'are to ensure the rapid movement of soft stools. The point of reflow is better. Based on the same _, the opening is 4 ~ 2 °, especially 6 ~ 15mm. 彳 To form the non-woven fabric of the top sheet 2, you can use hydrophilic, hot-rolled non-woven fabric, spinning glued non-woven fabric ... two ... In cloth and non-woven fabrics, the percentage of soft cloth that passes through quickly is to cloth temple. This temple non-woven non-woven fabric is better. It is composed of non-woven non-woven fabric and fiber called non-woven fabric, and its fineness is 5 · 5, especially 1 ~ he … From the point of softness and touch of the skin. You can also make a non-woven fabric with two kinds of fibers with different finenesses. At this time, a woven fabric is formed into a two-layer structure as the upper layer.

性之點較佳。 I 於本實施形態，以剛才所述之比頂壓縮率低地 形成上部吸收層12的KES壓縮率較佳。此事意味著頂片二方 面比上部吸收層12柔軟。藉此，尿片！的穿用感較佳。另= ，上部吸收層12方面，由於比頂片2相對地較難被壓縮，所 以即使在加上意外的體壓的情形’上部吸收層12亦很難被 壓縮，可以確保軟便的保持效果。依同樣的理由，上立。 口丨及 83867 -13 - 1230052 收層12<KES壓縮率，以比頂片2的KES壓縮率小^力倍 ‘特別疋〇·4倍〜0.8倍較佳。頂片2的KES壓縮率為 60〜95%，特別早 、 疋70〜90%，由給予穿用者柔軟的感覺，尿片 1的穿用感良好之點較佳。 頂片2，其紙的重量雖為15〜80g/m2，特別是20〜60g/m2， 由庠人便的透過性與質量風格之點較佳。另外，頂片2，在 gf/cm負荷下之厚度為〇·8〜3㈤以，特別是〇 8〜2.6 mm， 在50gf/cm負荷下之厚度為ojq 2，特別是〇 2J 〇 mm ’由柔軟度之點較佳。 本貝她形怨之尿片1之吸收體4係以圖3所顯示之方法適 當地製造。首先，由原匹21抽出由薄紙等所形成之硬紙。 被抽出 <硬紙20通過第}纖積機22的下部。第1纖積機22， 係在破碎供給至此之紙漿片23，形成纖維狀態之後，為了 I k矩/狀之織積體2 4而使用。又，雖未顯示於圖，不過 對第1纖積機22也供給高吸收性聚合物的粒子，該高吸收性 聚合物的粒子與被破碎形成纖維狀態之紙漿均一混合。矩 开/狀之纖積體24被載置於硬紙2〇的寬方向中央部。以圖3中 (a)顯示該狀態。纖積體24間歇地被載置於硬紙2〇上。 載置纖積體24之硬紙20，被導入眾所周知之折入裝置25 内’藉此其兩侧部被折入纖積體24的上侧。藉此纖積體24 以硬紙20覆蓋。其結果，形成由連續體所形 成之下部吸收 層。以圖3中（b)顯示該狀態。 如此所形成之下部吸收層之連續體，上下面被反轉，其 次’通過第2纖積機25的下部。第2纖積機25在破碎供給至 83867 -14- 1230052 此之紙漿片26形成纖維狀態之後’為了製造細長之纖積妒 27而使用。在第2纖積機25形成2條細長的纖積體27。各： 積體27係間歇地被製造，並分別被载置於下部吸收；的連 、續體上。纖積體27之載置位置，係位於下部吸收層㈣續 體之纖積體24的兩侧部上。以圖3中（c)顯示該狀態。 其次，構成由設置於第2纖積機25的下游之原匹28所抽出 之上部吸收層之連續片29,係被覆蓋於載置纖積體”之下 部吸收層的連續體上。片29係與下部吸收層的連績體相同 之寬度。以圖3中⑷顯示該狀態。藉此，製造包含有下部 吸收層、上部吸收層及抗壓縮層之吸收體的連婧體。哕連 續體’在後步驟於一定位置，在寬方向被裁斷，形成各個 之吸收體。 其次，-面參照圖4-面針對本發明之第2實施形態加以 說明。針對本實施形態，僅針對與第工實施形態不同之點加 以說明，特別是針對未說明之點，適度的適用關於^會施 形態所詳述之說明。另外，在圖4中，與圖i及圖2相同之構 件則賦予相同的符號。 圖4係相當於第!實施形態之圖2之圖。本實施形態之尿片 與第！實施形態之尿片不同之點，僅在於上部吸收層Η係配 置於-對抗壓縮層"間，該上部吸收層12係未覆蓋抗壓縮 層⑽上面之點。即使在本實施形態，與第1實施形態同樣 藉在上部吸收層i 2的兩側配置抗壓縮層11 ,亦可防止上 部吸收層12的壓壞’軟便的吸收及保持效果提高。但是， 僅上^吸收層12未覆蓋抗壓縮層11的上面之部分，防止上 83867 -15- 1230052 部吸收層1 2的壓壞之效果比第1實施形態小。 本發明之KES壓縮率係以其次之方法加以測定。測定裝 置使用kato-teku製之KES_FB3壓縮試驗機。使用該試驗機 測定壓縮面積2cm2，且在試樣之〇.5gf/cm2負荷下之厚度丁〇 。其次，以加壓速度20 μηι/秒壓縮試樣。隨著壓縮負荷逐 漸增加。壓縮進行到負荷達到5〇gf/cm2為止。接者，測定 5〇gf/cm、荷下之厚度Tm。以〇 5gf/cm2負荷下之厚度;^除 由〇.5gf/cm2負荷下之厚度丁 〇減去在5〇gf/cm2負荷下之厚度Sexuality is better. In this embodiment, the KES compression ratio for forming the upper absorption layer 12 at a lower than the top compression ratio just described is better. This means that the topsheet is softer on both sides than the upper absorbent layer 12. Take this diaper! The feeling of wearing is better. On the other hand, since the upper absorbent layer 12 is relatively harder to compress than the top sheet 2, it is difficult to compress the upper absorbent layer 12 even when an unexpected body pressure is applied, and a soft stool retention effect can be ensured. Go up for the same reason. Mouth and 83867 -13-1230052 Closure layer 12 < KES compression ratio is smaller than the KES compression ratio of the top sheet 2 ^ force times ‘especially 疋 0.4 times to 0.8 times better. The KES compression ratio of the top sheet 2 is 60 to 95%, particularly early, and 70 to 90%. From the viewpoint of giving a soft feeling to the wearer, the point that the diaper 1 has a good wearing feeling 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 in terms of human permeability and quality style. In addition, the thickness of the top sheet 2 under a gf / cm load is 0.8 to 3 mm, especially 0 to 2.6 mm, and the thickness under a 50 gf / cm load is ojq 2, especially 0 2 J 0 mm. The softness point is better. The absorbent body 4 of the benife diaper 1 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 < rigid paper 20 passes through the lower part of the fibrillator 22. The first fibrillator 22 is used for crushing the pulp sheet 23 supplied thereto to form a fiber state, and then it is used for the I k moment / shaped weave 24. 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 polymer are uniformly mixed with the pulp broken into a fibrous state. The moment-shaped fibrous body 24 is placed on the central portion in the width direction of the hard paper 20. 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 25 '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 it is crushed and supplied to 83867 -14-1230052, and the pulp sheet 26 is formed into a fibrous state. Two elongated fibrous bodies 27 are formed in the second fibrillator 25. Each: The integrated body 27 is manufactured intermittently, and is placed on the lower part of the absorption and continuous body. The placement positions of the fibrous body 27 are located on both sides of the fibrous body 24 of the lower absorption layer body. This state is shown in FIG. 3 (c). Next, a continuous sheet 29 constituting an upper absorbent layer drawn from an original sheet 28 provided downstream of the second fiberizer 25 is covered on the continuous sheet of the lower absorbent layer on which the fibrous body is placed. Sheet 29 It is the same width as the continuous body of the lower absorption layer. This state is shown by ⑷ in FIG. 3. Thereby, a continuous body including an absorption body including a lower absorption layer, an upper absorption layer, and an anti-compression layer is produced. 哕 Continuous body 'The latter step is cut at a certain position 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 and FIG. 4. The differences between the implementation forms will be explained, especially for the unexplained points, and the detailed description of the application form will be appropriately applied. In addition, in FIG. 4, the same components as those in FIGS. I and 2 are given the same Symbols. Fig. 4 is a view corresponding to Fig. 2 of the first embodiment. The diaper of this embodiment differs from the diaper of the! Embodiment only in that the upper absorbent layer is disposed on the anti-compression layer " The upper absorption layer 12 series Cover the points on the anti-compression layer. Even in this embodiment, similar to the first embodiment, by disposing the anti-compression layer 11 on both sides of the upper absorption layer i 2, it is possible to prevent the upper absorption layer 12 from being crushed. The absorption and retention effect is improved. However, only the upper part of the absorption layer 12 does not cover the upper part of the anti-compression layer 11, and the effect of preventing crushing of the upper 83867 -15-1230052 absorption layer 12 is smaller than that of the first embodiment. The KES compression ratio of the invention is measured by the next method. The measuring device is a KES_FB3 compression tester made by kato-teku. The tester is used to measure the compression area of 2 cm2 and the thickness under the load of 0.5 gf / cm2 of the sample. 〇 Secondly, the sample is compressed at a pressure rate of 20 μm / sec. As the compression load gradually increases. The compression is performed until the load reaches 50 gf / cm2. Then, the thickness Tm at 50 gf / cm and under load is measured. The thickness under a load of 0.5 gf / cm2; ^ divided by the thickness under a load of 0.5 gf / cm2 but minus the thickness under a load of 50 gf / cm2

For example, in the first embodiment, the entire area of the upper surface of the compression layer 1 is covered by the upper absorption layer 12, but instead of this, at least a part of the upper surface of the anti-compression layer 11 may be covered. In addition, in each of the two embodiments, the anti-compression layer i continuously extends in the longitudinal direction of the diaper 1, but instead of this, the anti-compression layer becomes discontinuous. In addition, the front end portion and / or the rear end portion of the compression-resistant layer 11 may be connected to the compression-resistant layers. The lower absorbing layer 10 may be not only a long rectangular shape, but also a sand timer or a T-shaped shape. Hereinafter, the present invention will be described in more detail with reference to examples. 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 Various top sheets of the types shown in Table 1 were produced. The table shows these KES compression ratios. 83867 -16- 1230052 (2) Manufacturing of upper absorption layer Various kinds of upper absorption 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 absorption layer Manufacture of 63% by weight of pulp fibers and 37% by weight of particles of superabsorbent polymer. The fiber with a weight of 478 g / m2 was cut into a rectangle with a width of 90 mm and a length of 285 mm. The fiber was wrapped with a thin paper with a weight of 16 g / m2 to form a lower absorbent body. (5) Back sheet Use a moisture-permeable back sheet with a weight of 40g / m2. The components obtained by using the above ⑴ 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 The soft stool absorbency was evaluated by the following methods for samples cut in the examples and ratios ❹m 彳 ㈣. The results are shown in Table 2. Soft stool absorbency Set the slope with an acrylic plate. Moderate setting (for example, 10 degrees). 4 scoops. The inclination angle of the acrylic plate is measured with an angle meter, and the inclination error is ± 1 83867 -17-1230052 degrees. In addition, the acrylic plate was leveled in a direction orthogonal to the oblique direction '. Before measuring the foot, confirm whether the sample is soft and comfortable on the acrylic board, and whether it is flowing down approximately in a straight line. Shifu,; * τ Adjust the degree of the acrylic plate when you are right below the machine. Secondly, an evaluation copy is placed on the acrylic board. The sample for evaluation was dripped at a rate of 3 g / sec from a broken glass tube having three inner diameters, and the sample was softened. At this time, the tip of the 'glass tube is changed from the dropping position of the evaluation sample to about 5 coffee. The dropping position of the evaluation sample is at a position of nearly 190 mm from the bottom end of the evaluation sample toward the upper side, and is located at the center of the width direction of the evaluation sample. The soft palate of the sample was dropped, and the running distance and diffusion area were measured, and the leakage was observed. The soft stool samples were prepared by adding kuranoru (PVA-based synthetic cleaning cream) i500g made by uehara chemical Co., Ltd. of Japan's Higashi Yongdo Co., Ltd., and adding Edible Blue No. 1 sold by the company Aizen of Tokyo Co., Ltd. .ig.

In this regard, 83867 -20-1230052 is shown in Table 1 and Table 2. In order to understand, it is obvious that the absorption and protection of the soft stool of A ^ good samples for a long time, from ~, not all cases have excellent advantages and The ancient pestle cranialis can prevent its leakage. For this reason, the ratio of several compression layers in the grass ^ ^ ^.. X shows that the absorption and retention of the soft stool of the sample is poor, and leakage due to surface liquid flow occurs. Furthermore, the disposable diapers for neonates were manufactured with the structure of _u-P.r and the original for evaluation in Example 1, and the dogwood fruits were subjected to practical adjustment, and it was confirmed that watery stools (soft stools) were absorbed. < There are many thoughts, and the leakage rate of stool is reduced. As described in detail above, the present invention lacks, J <disposable diapers, low viscosity in soft stools, etc., can effectively prevent its leakage. In addition, the disposable diaper according to the present invention can maintain the softness of the absorbent body, so that a comfortable wearing stomach can be obtained. Furthermore, in the wearing of the diaper, the cross-sectional shape I of the absorbent body in the width direction is changed to a slightly inverted Ω shape, and the diaper can fit the wearer's feet. The disposable diaper of the present invention is particularly suitable as a disposable diaper for newborns who have a lot of soft-riding rides.
