  • Method to impart coffee stain resistant to polyamide textile substances
    Patent number: 5359010
    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.

  • Method and composition to enhance acid dye stain resistance of polyamides by improving resistance to detergent washings and products thereof
    Patent number: 5348786
    Abstract: A method of imparting acid dye stain resistance to polyamide substrates having improved durability of the stain resistance to detergent washings comprising treating the polyamide substrate with an effective amount of a mixture of phenyl vinyl ether/maleic diacid copolymer and 2-(4-hydroxymethyl-phenoxy)-ethyl vinyl ether/maleic diacid copolymer, wherein the phenyl vinyl ether/maleic diacid copolymer is the stain resist agent, and the 2-(4-hydroxymethyl-phenoxy)-ethyl vinyl ether/maleic diacid copolymer is added to improve the durability of the stain resist agent.

  • Method to impart coffee stain resistance to polyamide fibers
    Patent number: 5135774
    Abstract: A method to impart coffee stain resistance to polyamide fibers such as those found in textile substrates (e.g., carpets). The method includes preparing an aqueous dispersion of charged microfine beads of 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, immersing the polyamide fiber in the aqueous dispersion so that the beads contact and coat the fiber via an electrostatic attraction. The aqueous dispersion is prepared by dissolving the polymer into a water-soluble solvent to form a solution, injecting the solution into water, and evaporating the solvent.
