Abstract: A carpet tile and process for making the carpet tile, wherein the carpet tile contains tufted face yarn, a primary backing, and at least three polymer-containing layers. The first layer is a pre-coat layer, and the second and third layers each contain a solventless hot melt adhesive that is extruded onto the pre-coat layer.

Abstract: Vinyl polymer adhesive using glass powder as a filler. The glass powder includes the use of recycled automotive and architectural glass as a filler material for several vinyl polymer adhesives, such as hot melt adhesives, polyvinyl chloride adhesives, and vinyl acetate-ethylene (VAE) emulsion adhesives. The glass powder may have an average particle size between 100 and 400 mesh.

Abstract: The floor covering includes multiple layers including a non-woven base layer, a VAE precoat applied to the non-woven woven base layer and overlaid by a first PVC layer. A fiberglass mat is applied over the first PVC layer and a second PVC layer is applied over the mat. A woven PVC layer is laminated by heat and pressure to the underlying second PVC layer. The woven PVC layer comprises monofilament or multifilament cores, preferably but not limited to, polyester filaments overlaid by a PVC coating.

Abstract: Described are methods of making a carpet by (a) providing a primary backing material having a front side and a back side, (b) tufting a yarn into the primary backing material to produce a carpet pile on the front side of the primary backing material and loops of the yarn on the back side of the primary backing material, (c) applying by slot coating a layer of a first melted coating composition onto the back side of the tufted primary backing material, (d) applying by slot coating a layer of a second melted coating composition onto the coating applied in step (c) thereby fixing the loops of the yarn to the primary backing material, and (e) applying and pressing a secondary backing onto the slot coated tackifying resin layers and pressing it to join the first and second tackifying resins and the primary backing and secondary backing and yarn loops together to form a carpet.
