    摘要: A water soluble polymer binder for binding a fibrous substrate comprises from about 25 weight percent to about 85 weight percent of an unsaturated carboxylic acid/unsaturated carboxylic acid ester terpolymer; from about 5 weight percent to about 35 weight percent of a divalent ion inhibitor; and from about 10 weight percent to about 60 weight percent of a hydrophilic cross-linkable polymer. In a preferred mode of the invention the hydrophilic cross-linkable polymer functions substantially as a divalent ion inhibitor and promotes hydrophilicity of the treated fabric eliminating the requirement of a separate divalent ion inhibitor. The binder composition is soluble in an aqueous environment having a divalent ion concentration less than about 50 ppm and a monovalent ion concentration of less than about 0.4 weight percent. Also disclosed is a water dispersible fibrous fabric having an effective amount of the binder distributed on the fibrous substrate and a method of making a water dispersible fibrous fabric.
