First Claim
Patent Images
1. As a surface covering, a dyed carpet or upholstery fabric comprising a polyolefin backing material having a polymeric coating thereon, and face yarns tufted to said backing, said coating being selected from:
- A. homopolymers and copolymers of a quaternary monomer prepared by reacting an epihalohydrin of the formula ##STR2## with an amine salt of the formula H2 C=C(R)C(O)O--A--N(CH3)2.sup.. HY; and
B. the reaction product of homopolymers or copolymers of said amine salt and said epihalohydrin;
wherein R is hydrogen or methyl, X is iodine, bromine or chlorine, A is a (C2 -C6) alkylene group having at least two carbon atoms in a chain between adjoined O and N atoms or A may be a polyoxyethylene group of the formula (CH2 CH2 O)x CH2 CH2 wherein x is at least 1, and Y is an anion.

Abstract
The dye receptivity of polyolefin materials, used as backings for tufted surface coverings such as carpets and upholstery fabrics, is improved by coating the polyolefin material with a self-curing polymeric binder containing a quaternary ammonium salt. The backing is thereby easily dyed on-shade with the tufted face yarns so as to hide the backing.
