Abstract
PURPOSE: To obtain a water absorbent articled having salt resistance and a high water absorptivity by fixing a polymeric cross-linked material containing a specific amount or more of sulfonic acid (salt) groups and having a specific amount or more of dissociating groups on a fiber with an organic polymeric binder. CONSTITUTION: A polymeric cross-linked material obtained by polymerizing a sulfonic acid group-containing unsaturated monomer, etc., e.g. vinylsulonic acid or acrylic sulfonic acid in the presence of a cross-linking agent [e.g. divinylbenzene or ethylene glycol (meth)acrylate] and containing >=0.5 mg equivalent/g sulfonic acid groups or salts thereof and >=1.0 mg equivalents/g dissociating groups is fixed on the surface of a fiber such as a synthetic, a natural or a regenerated fiber or a sheet comprising the fiber using an organic polymeric binder [a preferred example; (meth)acrylic acid containing >=1 mg equivalents/g hydrophilic groups (sulfonic acid groups or the like)] to afford a water absorbent article capable of absorbing even an aqueous liquid containing salts at a high concentration such as seawater at a high absorption ratio without deteriorating the absorbing ability with time.
