摘要： A water absorptive fabric including a layer of a water absorptive polymer whose major components consist of a cross-linked poly(metal salt of acrylic acid) and a water-soluble resin. The fabric may be produced by first impregnating a fabric substrate with a solution which contains a metal salt of acrylic acid in the form of a monomer, a cross-linking agent and a water-soluble resin, and then heating the impregnated fabric substrate to thereby copolymerize the monomer and the cross-linking agent, in the presence of the water-soluble resin.
