Abstract: A crosslinkable anionic binder composition which comprises an emulsion copolymer containing acrylamidoglycolic acid (AGA) and a zirconium III salt of an alpha or beta hydroxycarboxylic acid, the pH of the composition being from about 1.5 to 4.5. Provided are nonwoven binder compositions which are stable for extended periods prior to application of the binder composition onto the nonwoven substrate and initiation of crosslinking by application of heat.

Abstract: An emulsion composition is disclosed which provides a binder having good wet tensile strength and low heat seal temperature for nonwoven products which comprises an aqueous dispersion of a mixture consisting essentially of 50 to 95 wt % of a vinyl acetate-ethylene copolymer and 5 to 50 wt % of a vinyl acetate-ethylene-crosslinking monomer copolymer.

Abstract: A binder composition for nonwoven fabrics which comprises(a) a fugitive base salt of a phosphate ester surfactant or a carboxylate surfactant,(b) a latex comprising a vinyl acetate-ethylene-olefinically unsaturated carboxylic acid interpolymer colloidally suspended in water, the interpolymer containing about 0.5 to 7.0 weight percent olefinically unsaturated carboxylic acid and sufficient ethylene to provide the interpolymer with a glass transition temperature of from about -30.degree. to +20.degree. C., and(c) a polyvalent metal complex compound comprising a polyvalent metal ion and counter ions or ligands which hinder interaction of the polyvalent metal ion with the carboxylate and phosphate groups of the surfactant and interpolymer at room temperature, but at elevated temperature permit such interaction because the counter ions or ligands are expelled or are replaced by the anionic group of the surfactant and interpolymer.
