Abstract
Abstract TUFTED RUGS AND CARPETING HAVING A THERMOPLASTIC BACKING, E.G. A CLOSED CELL FOAM BACKING, ARE PREPARED BY APPLYING A HEAT-SENSITIVE PLASTISOL COMPOSITION TO THE BACK OF A MATERIAL COMPOSED OF TUFTED YARNS IN A THERMOPLASTIC BASE FABRIC, FUSING THE PLASTISOL COMPOSITION TO BIND THE BASE FABRIC AND TUFTED YARNS TOGETHER, AND THEN LAMINATING THE THERMOPLASTIC SHEET TO THE PLASTISOL LAYER USING THE PLASTISOL LAYER AS THE SOLE SOURCE OF A SENSIBLE HEAT TO MELT THE THERMOPLASTIC SHEET AND BOND IT TO THE PLASSTISOL LAYER.
