  • Polyolefin-backed nylon carpets with improved stability
    Patent number: 6329039
    Abstract: A carpet having nylon fibers containing a copper-based stabilizer has a polyolefin backing that partially envelops the nylon fibers. In the presence of the polyolefin backing, the copper induces degradation of the fibers and the backing. To prevent this degradation, a polyolefin backing of an ethylene/vinyl acetate copolymer which includes a stabilizing amount of a metal deactivator additive is employed. The metal deactivator is preferably 1,2-bis(3,5-di-tert-butyl-4-hydroxylhydrocinnamoyl) hydrazine. Such carpets are particularly suited for use in the manufacture of automotive carpets.
