摘要： Provided are an absorbent and an absorptive article containing the absorbent which has excellent water absorbability and leakage prevention ability, and has an intent to achieve reductions in the weight and thickness of an absorptive article.The absorbent comprises a polysaccharide that causes a gelation reaction in the presence of a polyvalent metal ion and a source of the polyvalent ion, in which the polyvalent ion is supplied simultaneously with or after dissolution and swelling of the polysaccharide. The absorptive article containing the absorbent can achieve excellent water absorbability and leakage prevention ability and thus reductions in the weight and thickness as the absorptive article.

摘要： A disposable diaper includes a pair of tape fasteners 6 that are used to connect front and rear waist regions 8, 10 to each other and are attached to side flaps 14 in the rear waist region 10 of the diaper. Each of the tape fasteners 6 includes fibrous nonwoven fabric made of thermoplastic synthetic resin fiber and thermoplastic synthetic resin coated on a substantially whole area of an outer surface of the fibrous nonwoven fabric wherein the thermoplastic synthetic resin forms a substantially smooth synthetic resin layer on outer surfaces of the respective tape fasteners. Thus, a free portion of each tape fastener is reliably prevented from being disengaged from a target tape even when the outer surface of the tape fastener and an inner surface of an underwear rub together during use of the diaper.

摘要： A topsheet for use in body fluid absorptive articles is so improved that collapse and clogging of liquid passages therein may be reliably avoided. The topsheet includes an upper sheet, provided with skin-contacting areas and liquid passages, and a lower sheet provided with skin-non-contacting areas, areas welded to the liquid passages, and exposed areas. The exposed areas are welded to each of the liquid passages around lower openings thereof so as to protect the liquid passage against collapse and clogging. The exposed areas define a skin-contacting surface which rises up into each of the liquid passages without extending above the upper surface of the skin-contacting areas. The upper sheet cooperates with the lower sheet to define cavities extending in the direction of the topsheet thickness.

摘要： A water-absorbent structure comprises an assembly of thermoplastic synthetic fibers, cellulose-based fibers, super-absorbent polymer and water-pervious sheets wrapping these components together. The assembly is a honeycomb construction having a plurality of through-holes and normally in a compressed state. Upon water permeation into the water-absorbent structure, the super-absorbent polymer is swollen and softened and the assembly is swollen so that the through-holes restore the initial state before the assembly has been compressed.
