Abstract:
A process for preparing a laminated carpet by adhesively bonding a secondary backing to a greige good comprising carpet yarns tufted into a primary backing, said process comprising:a) applying to the primary backing side of said greige good, a reactive polyurethane adhesive comprising an isocyanate-functional component and an isocyanate-reactive component, to form an adhesive-coated greige good;b) prior to contacting said adhesive-coated greige good with said secondary backing, promoting adherence of the secondary backing to the adhesive-coated greige good by applying a non-advancing polyurethane-reactive skip coating composition to said secondary backing;c) contacting said secondary backing with the adhesive-coated surface of said greige good to form a laminate; andd) curing said reactive polyurethane adhesive to form a laminated carpet,wherein said non-advancing polyurethane-reactive skip coat composition, following application to said secondary backing, will exhibit greater adhesion to the polyurethane adhesive-coated greige good than is obtained from the same areal weight of a skip coat having the same composition as said reactive polyurethane adhesive.
