Abstract
A water soluble polymer comprising from about 25 weight % to about 90 weight % of an unsaturated carboxylic acid/unsaturated carboxylic acid ester terpolymer; from about 10 weight % to about 75 weight % of a divalent ion inhibitor and from about 0 weight % to about 10 weight % of a plasticizer 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 0.5 weight %. Also disclosed is a water dispersible fibrous fabric having a fibrous substrate and an effective amount of the binder distributed on the substrate and a method of making a water dispersible fibrous fabric.
Claims24
An ion sensitive water soluble binder composition for binding fibrous material into an integrated fabric, said binder composition comprising from about 25 weight % to about 90 weight % of an unsaturated carboxylic acid/unsaturated carboxylic acid ester copolymer;
- from about 10 weight % to about 75 weight % of a divalent ion inhibitor and from about 0 weight % to about 10 weight % of a plasticizer, wherein said water soluble 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 0.5 weight % and is insoluble in an aqueous solution having a concentration of divalent ions greater than about 50 ppm and said unsaturated carboxylic acid/unsaturated carboxylic acid ester copolymer is a copolymer of from 10 to 90 weight percent of acrylic acid and/or methacrylic acid and 90 to 10 weight percent of at least one acrylic ester and/or methacrylic ester having an alkyl group of 1 to 18 carbons or a cycloalkyl group of 3 to 18 carbons.
