  • Publication number: 20040013847
    Abstract: 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.

  • Publication number: 20020082574
    Abstract: A body fluid absorbent wearing article includes a liquid-absorbent panel. The panel is composed of a first fibrous assembly panel lying on the side of a topsheet and a second fibrous assembly panel underlying the first sub-panel. The first sub-panel has a flat portion, a plurality of protuberant portions and a plurality of wall portions. The first sub-panel has a fiber density progressively increasing as the first panel gets nearer to the second sub-panel having a fiber density higher than that of the first panel. The panel thus formed rapidly spreads body fluids thereover and prevent the body fluids from flowing back to a top surface of the article.

  • Publication number: 20020049417
    Abstract: A body fluid absorbent panel including fibers containing hydrophilic fibers by 80-100% by weight and superabsorbent polymer particles contains heat-fusible fibers which are fused to intertwine the fibers and thereby to form a three-dimensional network structure wherein the high absorption polymer particles are held between respective pairs of the adjacent fibers or bonded to the fibers by means of binder, and thereby falling off of the polymer particles can be prevented and the absorption efficiency can be improved.
