摘要： An absorbent product comprising a liquid permeable surface sheet, a liquid nonpermeable back sheet and an absorbent layer located therebetween, wherein the absorbent layer comprises a water nonswellable synthetic fiber (a) and optionally cellulose fiber (b), and a water-absorbent resin (c), with the weight ratio of (a):(b) being (100 to 20):(0 to 80) and the percentage content of (c) based on the weight sum of (a), (b) and (c) is 25 to 75 weight %. The absorbent layer is treated with polyoxyalkylene-modified silicone surface active agent (d1) and/or a nonsilicone surface active agent having HLB of 8 to 14 (d2). Absorbent products of the present invention exhibit excellent shape retention in the moist state and good permeability and diffusibility for the absorbed liquid. Accordingly, they provide excellent surface dryness, reduced leakage and thus can be comfortably used for a long time and effectively applied to disposable diapers, sanitary napkins and incontinence pads.
摘要翻译： 1.一种吸收性物品，其特征在于，包括透液性表面片，液体不可渗透的背片和位于其间的吸收层，其中所述吸收层包含水不可渗透的合成纤维（a）和任选的纤维素纤维（b）和吸水性树脂 c）以（a），（b）和（b）和（b）的重量和计，（a）：（b）的重量比为（100〜20）：（0〜80） c）为25〜75重量％。吸收层用聚氧化烯改性的硅氧烷表面活性剂（d1）和/或HLB为8〜14（d2）的非硅酮表面活性剂处理。本发明的吸收性物品在潮湿状态下表现出优异的形状保持性，并且对吸收液体具有良好的渗透性和扩散性。因此，它们提供优异的表面干燥度，减少泄漏，因此可以长时间舒适地使用，并有效地应用于一次性尿布，卫生巾和失禁垫。

摘要： The present invention relates to a water absorbent composition comprising 100 parts by weight of water absorbing polymer particles and 0.5 to 30 parts of a resin powder having heat adhesion property at 50.degree.-200.degree. C. The present invention also relates to a water absorbing material and water absorbing products using the said water absorbing material comprising the water absorbing polymer particles, a resin having heat adhesion property at 50.degree.-200.degree. C. and fibrous material, wherein the water absorbing polymer particles are adhered to the fibrous material through the resin by heat treatment at temperature exceeding the temperature exhibits heat adhesion property of the resin. The water absorbent composition of the present invention provides excellent adhesion to a fibrous material, while it maintains the water absorbency of the original water absorbing polymer, and is consequently useful as raw material for sanitary goods such as disposable diapers and sanitary napkins etc. The water absorbing material of the present invention has excellent water absorbency, absorbing speed and shape retention property after water absorption. Consequently, it is useful for water absorptive goods such as disposable diapers and sanitary napkins.
