Abstract
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.

A water absorptive fabric having sufficient flexibility to be formed about a communication cable which includes a layer of a water absorptive polymeric material formed by the in situ reaction of a metal salt of acrylic acid, a cross-linking agent and a water soluble resin.
A process of producing a water absorptive fabric, comprising the steps of:
- 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 heating the impregnated fabric substrate to thereby copolymerize said monomer and said cross-linking agent, in the presence of said water-soluble resin.
