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.

Abstract: AN INTEGRAL TUFTED CARPET, WHICH CARPET COMPRISES IN COMBINATION: A BASE FABRIC SHEET COMPRISING THERMOPLASTIC FIBERS, WHICH FIBERS ARE SUBJECT TO SHRINKAGE AT TEMPERATURES IN EXCESS OF ABOUT 200*F.; TUFTED YARNS SECURED THROUGH AND TO SAID BASE FABRIC SHEET TO PROVIDE A TUFTED PILE FACE SURFACE AND YARN LOOPS ON THE BACK SURFACE; A LAYER OF A FUSED VINYL CHLORIDE RESIN PLASTISOL COMPOSITION BONDED TO THE BACK SURFACE, THE FUSED LAYER SUBSTANTIALLY FILING THE INTERSTICES BETWEEN THE TUFTED YARN LOOPS AND THE BASE FABRIC, THE FUSED PLASTISOL COMPOSITION THE SOLE ADHESIVE EMPLOYED TO LOCK THE TUFTED YARNS TO THE BASE FABRIC, THE THERMOPLASTIC FIBERS OF THE BASE FABRIC MAINTAINED IN SUBSTANTIALLY NONHEAT-SHRINKABLE FORM; AND A LAYER OF A THERMOPLASTIC FOAM, ONE SURFACE OF THE FOAM SHEET BONDED TO THE SURFACE OF THE FUSED PLASTISOL COMPOSITION, THE LAYERS BONDED TO EACH OTHER SOLELY BY THE MELTED AND COOLED SURFACES OF THE THERMOPLASTIC VINYL CHLORIDE RESIN AND THE FOAM.
