ABSTRACT:
The back side of a tufted carpet is treated with an agent which will substantially lower the breaking strength of the yarn at points on the backstitch of the yarn. The face yarns or tufts of the carpet are unaffected by the agent. The back of the carpet is covered by a conventional latex coating to bind the carpet yarns in position to the carpet backing. A force engaging an individual tuft and pulling it from the body of the carpet will pull out individual tufts rather than unravel a strand of yarn from the carpet backing.
