Abstract: A method for preparing carpet by using polyurethane to anneal secondary backing to a greige, comprising fibers attached to a primary backing using a roller application system. The greige is conditioned prior to coating and the polyurethane coated greige is contacted with the secondary backing and the laminate is tensioned and supported to maintain the laminate structure substantially through the polyurethane curing process.

Abstract: A method for preparing carpet by using polyurethane to anneal secondary backing to a greige, comprising fibers attached to a primary backing. The polyurethane monomers are mixed just prior to application to the greige primary backing allowing the relatively low viscosity polyurethane to penetrate the fibers of the primary backing to aid in fiber lock. The polyurethane is puddle between two rollers that coat a layer of polyurethane onto the greige. The polyurethane coated greige is then contacted with the secondary backing before complete polymerization to insure sufficient tack to hold the backings together resulting in a durable carpet requiring a relatively low weight of polyurethane monomers.
