Abstract
Abstract A tufted carpet coated with a fused thermoplastic resin on the underside of a tufted primary backing is formed by impregnating the primary backing with a liquid plasticizer either undiluted or diluted with a solvent for the plasticizer, coating the underside of the primary backing with a solid resin powder capable of being plasticized by the plasticizer and fusing the resin coating by heating. The primary backing can be tufted subsequent to impregnation and preferably prior to impregnation with the plasticizer. In one embodiment a secondary backing, either impregnated with plasticizer or containing no plasticizer is applied to the resin coating either prior to or during the time the resin is fused to adhere the primary backing to the secondary backing.
