Carpet and textile coating compositions are formulated to include fiber or flock pieces so as to improve the tuft pull strength and dimensional stability of the carpet or textile. The coating compositions comprise 10 to 70%, by weight, of a latex binder and 30 to 90%, by weight, of at least one filler, wherein the filler comprises about 0.001 to 100%, by weight, of fiber or flock pieces. Any natural or synthetic fiber may be used in the coating compositions of this invention.

Fiber reinforcement of carpet and textile coatings

A thickened aqueous copolymer solution useful for thickening and improving the properties of latex systems comprising a copolymer having as monomeric units: about 79-99 percent of a (meth)acrylic acid salt of sodium, potassium, or ammonium; about 0-20 percent of (meth)acrylic acid; about 0-20 percent of a lower alkyl ester of (meth)acrylic acid; about 1-21 percent of surfactant units selected from the urea reaction product of a monoethylenically unsaturated monoisocyanate with a nonionic surfactant having amine functionality; and about 0-1 percent of a copolymerizable polyethylenically unsatured monomer, said percentages being by weight based on the total weight of monomeric units in said copolymer.
