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.

Liant polymère soluble à l'eau pour lier un substrat fibreux. Ce liant comprend entre 25 pour-cent en poids et 85 pour-cent en poids environ d'un terpolymère acide carboxylique insaturé/ester d'acide carboxylique insaturé; entre 5 pour-cent en poids et 35 pour-cent en poids environ d'un inhibiteur d'ions bivalents; et entre 10 pour-cent en poids et 60 pour-cent en poids environ d'un polymère hydrophile pouvant être réticulé. Dans une forme préférée, le polymère hydrophile pouvant être réticulé agit sensiblement comme un inhibiteur d'ions bivalents et favorise les qualités hydrophiles de la texture traitée, rendant l'utilisation d'un inhibiteur ionique bivalent distinct superflue. La composition de liant est soluble dans un environnement aqueux présentant une concentration en ions bivalents inférieure à 50 ppm et une concentration en ions monovalents inférieure à 0,4 pour-cent en poids environ. L'invention décrit en outre une texture fibreuse dispersible dans l'eau comportant une quantité efficace de ce liant réparti sur le substrat fibreux, ainsi qu'un procédé pour produire cette texture fibreuse dispersible dans l'eau.
