PROCESS FOR PRODUCING A BACKING FOR TUFTED CARPETS AND BACKING PRODUCED BY THIS PROCESS

摘要

A process for producing a backing for tufted carpets proposes that a carrier layer (2) and a layer of non-woven fibrous material (4) be brought together and bonded under the effect of heat. The bonding is effected by means of an adhesive layer (6) consisting of a thermoplastic plastics material which has a lower melting point than the material of the two layers (2) and (4). The heat is adjusted accordingly so that only the adhesive layer (6) melts and partially surrounds and embeds the areas of the two layers which are to be bonded (2) and (4) which are closest to said adhesive layer. Any melting or fusion of the materials of the two layers themselves is thus avoided. IMAGE
