ABSTRACT:
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.
