  • Patent number: 6406574
    Abstract: A method for manufacturing a vinyl-backed carpet is described wherein the carpet is assembled in a single continuous finishing line. The method includes the application of a vinyl plastisol reinforcing layer directly to the back of unfinished woven or tufted carpet material. The method allows the use of a thinner vinyl layer that results in savings in material, processing steps, and energy required for curing.
    Type: Grant

  • Patent number: 6162748
    Abstract: The present invention relates to a method of preparing a woven textile surface covering. The method involves applying a resin composition layer onto a back surface of a woven layer. The woven layer is formed by weaving warp and weft yarns. The resin composition layer is effective for bonding to the warp and weft yarns. The resin composition layer is provided with a resin composition and a cross-linking agent effective to wet, penetrate, and encapsulate the warp and weft yarns. The resin composition layer occupies the interstices of the warp and weft yarns and when the resin is heated, the resin cross-links with the woven layer. A backing layer is then contacted with the surface of the heated resin composition layer thereby bonding the backing layer to the resin composition layer. The present invention also relates to a woven textile surface covering having a first layer with a decorative surface and a back surface. The first layer is formed from woven warp and weft yarns that have interstices therebetween.
