摘要： A powdered resin of high absorption power (SAP) has heretofore been used as a water retentive material for sanitary products, such as sanitary napkin, a paper diaper and an incontinence pad. This water retentive material is used by being held between two paper sheets but the powdered SAP comes off easily from an absorption member. Moreover, even when the SAP is in a dried powdered state or in a water-absorbed gel state, it is moved between a top sheet and a back sheet in accordance with the movement of a user of the sanitary product. Consequently, the water absorption power decreases, and the shape stability lowers. Moreover, since the SAP in a water-absorbed gel state is sticky, the user feels unpleasant. A cellulose fiber, such as a viscose rayon fiber containing uniformly a non-cellulose material of a high water absorption power, such as polyacrylate is manufactured, from which fiber a fiber web or a nonwoven cloth is manufactured, which is used as a water retentive material in an absorption member. This fiber has high water absorption power and moreover a high water retentivity, i.e. large absorbed water-holding power. Accordingly, an absorption member formed of a sheet made of this fiber has a stable shape both when it is in a dry state and when it is in a water-absorbed state, and, moreover, it has high water absorption power and a high water retentivity. Therefore, when this water retentive sheet is used, a thin absorption member of high water absorption power can be provided.
摘要翻译：迄今为止，已经将高吸收能力的粉末状树脂（SAP）用作诸如卫生巾，纸尿布和失禁垫的卫生产品的保水材料。这种保水材料被保持在两个纸张之间，但是粉末状SAP容易从吸收构件中脱出。此外，即使当SAP处于干燥的粉末状态或吸水凝胶状态时，根据卫生产品的使用者的移动，其在顶片和背片之间移动。因此，吸水力降低，形状稳定性下降。此外，由于在吸水凝胶状态下的SAP是粘性的，所以使用者感到不愉快。制造纤维素纤维，例如均匀地含有高吸水力的非纤维素材料的粘胶人造丝纤维，如聚丙烯酸酯，由纤维素纤维制成纤维网或无纺布，用作保水剂吸收构件中的材料。该纤维具有高吸水能力，而且具有高的保水性，即大的吸收保水力。因此，由这种纤维制成的片材形成的吸收部件在处于干燥状态时和处于吸水状态时都具有稳定的形状，此外，它具有高的吸水力和高的水分保持性。因此，当使用这种保水片时，可以提供具有高吸水能力的薄吸收构件。

摘要： A biodegradable and hydrolyzable sheet which comprises at least one biodegradable synthetic fiber, at least one natural fiber and/or regenerated fiber, the fibers being bonded to one another with a binder which substantially loses its adhesive power in water. This sheet has a combination of a given tensile strength, a good softness, and a desired liquid absorption capability and, in addition, a desired biodegradability. Therefore, the sheet, when flushed away in a flush toilet, does not cause any significant increase in solid residues in a septic tank and sewage treatment equipment, rendering the sheet suitable particularly for wet wipes.
摘要翻译：一种可生物降解和可水解的片材，其包含至少一种可生物降解的合成纤维，至少一种天然纤维和/或再生纤维，所述纤维用粘合剂彼此粘合，所述粘合剂基本上损失其在水中的粘合力。该片材具有给定的拉伸强度，良好的柔软性和所需的液体吸收能力的组合，并且还具有期望的生物降解性。因此，当在冲水马桶中冲洗时，该片材不会导致化粪池和污水处理设备中固体残留物的显着增加，使得该片材特别适用于湿巾。

摘要： A highly water-absorbing resin composition obtained by fusing or fixing a thermoplastic resin to the surface of a highly water-absorbing resin either through an adhesive binder or directly, and its composition comprises 1 to 100 parts by weight of the thermoplastic resin per 100 parts by weight of the highly water-absorbing resin. When this composition is employed, a highly water-absorbing resin can be firmly bonded to a fibrous substrate, and a water-absorbing material which stably holds the highly water-absorbing resin even after water absorption can be obtained. Accordingly, a greater amount of the highly water-absorbing resin can be held by a substrate such as a fibrous substrate than in the prior art, and the present invention can provide a water-absorbing composite material suitable for various applications, e.g. sanitary field such as a paper diaper and sanitary napkin, and water-absorbing materials of industrial materials such as for horticulture and agriculture and foodstuffs.
摘要翻译：通过粘合剂粘合剂或直接将热塑性树脂熔融或固定在高吸水性树脂的表面而得到的高吸水性树脂组合物及其组合物包含1至100重量份热塑性树脂/ 100份的高吸水性树脂。当使用该组合物时，可以将高吸水性树脂牢固地粘合到纤维基材上，并且可以获得即使在吸水后稳定地保持高吸水性树脂的吸水材料。因此，与现有技术相比，通过诸如纤维质基材的基材可以保持更多量的高吸水性树脂，并且本发明可以提供适合于各种应用的吸水复合材料，例如，诸如纸尿布和卫生巾的卫生领域，以及用于园艺和农业和食品的工业材料的吸水材料。

摘要： A particulate deodorant resin composition comprising a water-absorbent resin and powdery zeolite dispersed within the resin particles. The composition produces the effect of deodorizing the absorbed body fluid while retaining the water-absorbent function inherent in water-absorbent resins. When, therefore, used as sanitary materials such as paper diaper or sanitary goods, it is featured by not only the inherent absorbent effect, but also the deodorant effect.
