    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.

    摘要: A disposable body fluid absorbent wearing article includes a liquid-pervious topsheet including plastic film layer sections, liquid-pervious openings and a first fibrous layer bonded to the lower surface of the film layer sections. A second fibrous layer forming a liquid-absorbent core is contiguous to the lower surface of a first fibrous layer and a third fibrous layer is contiguous to the lower surface of the second fibrous layer. The wearing article is constructed so that its Klemm's water absorbency may progressively increase in the order of the first fibrous layer, the second fibrous layer and the third fibrous layer.
