The disclosure relates to a carpet, a process for manufacturing a carpet and a method for recycling a carpet. The carpet of the present disclosure includes a primary backing having tufts of synthetic carpet fibers protruding from a top surface and, optionally, a secondary backing, with an extruded sheet of an isotactic polyolefin polymer between and integrally fused to a bottom surface of the primary backing and an upper surface of the secondary backing. The process for manufacturing the recyclable carpet includes contacting the extruded sheet with the primary backing and, optionally, the secondary backing, at a temperature sufficiently high to integrally fuse the extruded sheet to the respective backing. The method for recycling synthetic carpet of the type described includes manufacturing the carpet, collecting portions of the carpet, and melting the collected portions to make a feedstock.

Carpet and techniques for making and recycling same

Crystallizable hot melt adhesive compositions comprising block copolyesteramides and alkali metal carboxylates. The block copolyesteramides comprise hard or crystalline polyester blocks and soft or amorphous polyamide blocks in the weight ratio of 2:3 to 4:1. The alkali metal carboxylates provide a concentration of alkali metal cation in the range of 0.1 to 6 meq per 100 parts by weight of copolyesteramide. The hot melt adhesive compositions are useful for bonding plastic parts to form plastic structures which are relatively free of bond line distortion.

Hot melt adhesive compositions

A polymeric blend formed from recycled carpet scrap and selected compatibilizing agents and/or a poly(ethylene-co-omylacetate) and the products produced from such blend.

Recycling of carpet scrap

The present invention pertains to carpet and method of making it. In one aspect, the carpet includes (a) a primary backing which has a face and a back surface, (b) a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing, (c) an adhesive backing, (d) an optional secondary backing adjacent to the adhesive backing, and (e) at least one homogeneously branched linear ethylene polymer. The method includes extrusion coating at least one homogeneously branched linear ethylene polymer onto the back surface of a primary backing to provide an adhesive backing. The method can include additional steps or procedures, either separately or in various combinations. Additional steps and procedures include preheating the primary backing prior the extrusion step, multilayer adhesive backings, washing or scouring the primary backing prior the extrusion step, and utilizing adhesive polymeric additives, high heat content fillers, blowing agents and/or implosion agents. The constructions and methods described herein are particularly suited for making carpet tile.

Carpet, carpet backings and methods

Polymer resins incorporating nanoparticles having a particle size in the range of 1-100 nm and a narrow particle size distribution have improved tensile properties and scratch resistance.

Nanoparticle-filled polymers

Hot melt compositions containing copolymer of ethylene and vinyl acetate and/or alkyl acrylate wherein the alkyl group contains 1-18 carbon atoms; atactic polypropylene; and vulcanized rubber which are particularly useful as hot melt carpet backing adhesives and as hot melt pressure sensitive adhesives.
