Abstract
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. The woven textile surface covering has a second layer that has a yarn engaging surface where at least a portion of the yarn engaging surface occupies the interstices of the warp and weft yarns. The second layer includes a resin composition and a cross-linking agent. The cross-linking agent is effective for cross-linking the resin composition with the warp and weft yarns. The resin composition and the cross-linking agent are effective for wetting, penetrating, and encapsulating at least a portion of the warp and weft yarns.
