Abstract
Abstract A carpet including yarn pile extending from the face of a primary backing and a secondary backing bonded to the back of the primary backing has a thin film of liquid impervious thermoplastic material bonded either to the rear of the primary backing or to the rear of the secondary backing to provide a fluid barrier for preventing spills from seeping through to a floor beneath the carpet. The film is bonded to either backing by a hot melt thermoplastic adhesive or other non-aqueous adhesive. Additionally, the method of providing such fluid barrier for the carpet is disclosed.
