ABSTRACT:
Non-adhesive activated ("non-AA") polyester cord, or aramid cord, and fabrics made therefrom, may be coated in a two-step process, the first step of which is conventional. In the novel second step, after the cord is conventionally pre-coated in the first step, it is dipped in a R/F-free latex of a diene polymer in which an acrylic resin having a mol wt. in the range from about 100,000 to about 1,000,000 is dispersed. The acrylic resin resin is a copolymer selected from the group consisting of two or more monomers, one of which is (meth)acrylic acid and another is a lower alkyl(meth)acrylic acid ester, the monomers having the configuration ##STR1## wherein, R represents H, methyl, ethyl, Cl or CN, and, X represents hydroxyl (OH), hydroxymethylamino (NHCH.sub.2 OH), or alkoxy (O-alkyl) having from 1 to 4 carbon atoms; and, optionally, in addition the copolymer may include a vinyl aromatic monomer having from 8 to about 18 carbon atoms.
