Abstract
Carpets having stain resistant pile fibers and a backing that is substantially impervious to water are described. The impervious backing prevents water from passing through the carpet and into the underpad where its presence causes rotting and mildewing of the underpad and other carpet components. The impervious backing also permits washing of the carpet with generous amounts of water without wetting the underpad.
Claims6
A carpet comprising a primary backing coated with an adhesive composition and a pile consisting essentially of fibers attached to said primary backing, said carpet being characterized in that said fibers are shaped from nylon 66 or nylon 6 polymer modified to contain as an integral part of its polymer chain aromatic sulfonate units in an amount sufficient to improve the acid dye-resist properties of said fibers and said adhesive composition contains a fluorochemical in an amount sufficient to render said backing substantially impervious to water.
