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.
