Description

ABSTRACT:
An improved cushioned carpet fabric is provided. The cushioned carpet comprises a primary carpet having a primary base and a plurality of pile-forming yarns projecting outwardly from one side. A layer of reinforcement material is bonded to the primary base on the side opposite the pile forming yarns. The reinforcement layer is adjacent to and embedded in, a cushion layer of a polymer such as a polyurethane. There is preferably no additional adhesive between the cushion layer and the layer of reinforcement material since the primary carpet fabric is mated in-situ to the polyurethane-forming composition without preheating the polyurethane-forming composition. An apparatus and process for forming the cushioned carpet fabric of the present invention are also provided.
