Abstract
The disclosure relates to a carpet product, a process for manufacturing carpet, and an apparatus used in a carpet manufacturing process. The carpet product is made from tufted polymer filament yarn and includes a sheet of extruded polypropylene, integrally fused to the individual yarn filaments of the yarn back loops. The yarn fibers are substantially all secured to the integrally fused sheet so that the carpet resists fuzzing. The process includes providing a carpet base having a primary backing penetrated by yarn, applying heat to the underside of the base, extruding a heated sheet of polymer and continuously contacting the heated extruded sheet of polymer with the base thereby integrally fusing the base to the extruded sheet. The apparatus includes a source of carpet precursor, a heated cylinder for heating the underside of the carpet, an extruder and a casting roll against which the extruded sheet and heated carpet are pressed.
