  • SURFACE COVERING WITH WEAR LAYER HAVING DISPERSED WEAR RESISTANT PARTICLES AND METHOD OF MAKING THE SAME
    Publication number: 20160059526
    Abstract: A surface covering includes a base layer, a wear layer, and a topcoat layer. The wear layer is laminated to the base layer. The wear layer comprises a polymeric binder system having wear resistant particles dispersed therein. The wear layer is formed by dispersing a plurality of wear resistant particles into a liquid to form a stable liquid dispersion, blending the stable liquid dispersion into a polymeric resin to form a mixture, and extruding the mixture to form the wear layer.

  • Method of coating an open weave fabric
    Patent number: 4379730
    Abstract: A method of applying a latex coating to a carpet secondary backing by means of an applicator roll and a metering roll which travel in reverse rotation and different tangential speeds. The carpet secondary backing travels between a pressure roll and the applicator roll and a film of a coating material is applied to the backing. The backing is an open weave structure and the coating is applied primarily to the strands of the backing and not particularly to the open area of the backing.
