    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.
