<p>A method for the manufacture of a tufted pile carpet is disclosed. The method comprises contacting a polyolefin composition of at least one grafted polymer selected from polyolefin, olefin copolymer and olefin terpolymer with a tufted primary carpet backing. The tufted primary carpet backing is comprised of fibres selected from at least one of polyamide fibres, polyester fibres, polypropylene fibres, acrylic fibres, rayon fibres and natural fibres. The grafted polymer is selected from at least one of homopolymers of ethylene and propylene, copolymers of ethylene and propylene, terpolymers of ethylene, propylene and diene and copolymers of ethylene with at least one of a C3-C10 hydrocarbon alpha-olefin, vinyl acetate, alkyl acrylate or alkyl methacrylate that has been grafted with at least one monomer selected from ethylenically unsaturated dicarboxylic acids and anhydrides thereof. The polyolefin composition is heated to a temperature above the melting point of the polyolefin composition, and maintained in contact with the tufted primary carpet backing, at a temperature above the melting point of the polyolefin composition under a pressure and for a period of time sufficient to cause the polyolefin composition to flow around the fibres of the tufted carpet backing. The polyolefin composition is maintained in contact with the tufted primary carpet backing and at a temperature above the melting point of the polyolefin composition for a further period of a least 30 seconds. The resultant carpet is then cooled below the melting point of the composition. The polyolefin composition may also be placed between a tufted primary carpet backing and a secondary carpet backing and contacting the composition. Tufted pile carpets wherein such a tufted primary carpet backing has been stabilized with such a polyolefin composition are also disclosed.</p> |
