ABSORPTIVE MATERIAL, METHOD FOR PRODUCING THE SAME AND ABSORPTIVE ARTICLE USING THE SAME

摘要

An object of the present invention is to provide an absorbent structure, its production process, and an absorbent article comprising the absorbent structure, wherein, in the absorbent structure, a water-absorbent resin is fixed, and the restrictions, due to this fixation, on the swelling are small, and the absorbent structure is excellent in absorption properties and usable favorably for thin type absorbent articles in which the water-absorbent resin is used in an increased amount. As a means of achieving this object, the absorbent structure according to the present invention comprises a base material, a water-absorbent resin layer, and a hot-melt adhesive, wherein the water-absorbent resin layer includes a water-absorbent resin as an essential material and is fixed to the base material with the hot-melt adhesive; with the absorbent structure being characterized by: being a multi-layered structure including at least the following three layers: a layer of the base material; the water-absorbent resin layer; and the hot-melt adhesive; and displaying an average space ratio of 30 to 70 % and an average space radius of 100 to 300 mu m during saturation-swelling without load.
