ABSTRACT:
The present invention provides methods and compositions to impart coffee stain resistance to polyamide textile substrates such as carpets. The compositions comprise either (i) a copolymer selected from the group consisting of a hydrolyzed aromatic-containing vinyl ether maleic anhydride copolymer, a half ester of an aromatic-containing vinyl ether maleic anhydride copolymer, and mixtures thereof, or (ii) an aromatic-containing acrylate copolymerized with an acid selected from the group consisting of acrylic acid and maleic acid. The coffee stain-resistant polyamide textile substrates made are also part of the invention.
