    Abstract: A process for preparation of a tufted polyamide-type fiber carpet is provided. A primary backing tufted with yarn comprised of at least 85% by weight of fibers selected from the group nylon fibers, wool fibers, and blends thereof is provided. A molten polymer adhesive is provided on the back side of the tufted primary backing, the polymer adhesive consisting of at least 85% by weight of one or more ethylene copolymers each comprised of 50 to 95 weight % of ethylene, and 5-50 weight % of at least one comonomer selected from the group of esters and carboxylic acids. The tufted primary backing and the molten polymer adhesive layer are compressed under a moving belt that applies a pressure of at least 1 N/cm for a period of at least 5 seconds during which time the polymer adhesive remains in a molten state. The molten polymer adhesive then cooled to a temperature below the melting point of said molten adhesive. A secondary backing may be placed over the molten polymer adhesive on the back of the primary backing.

    Abstract: A composite backing (38) suitable for use in the manufacturing of carpeting, particularly tufted synthetic turf carpeting, or any other fabric product where dimensional stability in the presence of thermal or moisture gradients is desirable. The composite backing (38) comprises reinforcement strands (20) integrated into a woven backing fabric (10). The reinforcement strands (20) may be laid in an open network structure and needlepunched into a woven backing (10) or may also be integrated into the woven backing by directly weaving the reinforcement strands (20) into the woven backing (10) as it is being fabricated. A synthetic turf product may be constructed by tufting the composite backing.

    Abstract: Seam strips (50) are provided in a textile covering for a floor, wall or ceiling which are exposed and afford an aesthetic surface treatment. The seam strips comprise inverted T-shaped strips with an upstanding web (52) terminating in a margin short of the pile height and a pair of flanges (54, 56) projecting laterally from each of the lower opposite sides of the web (52). The flanges (54, 56) have holes (60) for securing, by way of screws or nails, the strips (50) to the underlying floor, wall or ceiling. The adjacent edges of the textile covering are secured to the upper surfaces of the flanges (54, 56). The textile coverings preferably have the backstitches (14) of tufts and portions of the primary backing forming an exposed surface which, together with the exposed margin of the strips (50), form an aesthetically pleasing surface treatment.
