Abstract

Laminated carpeting consisting of a secondary backing adhered to a greige good of yarn tufted into a primary backing are prepared from polyurethane adhesives by single puddle processes which allow for lowered use of polyurethane while producing carpets exhibiting excellent delamination strength. Preferably, a reactive polyurethane system is employed as a primary adhesive, and the secondary backing is skip-coated with a minor amount of a non-advancing skip coat.
