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.

Zirconium (III) salts as cure co-catalysts for nonwoven binders

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.
