ABSTRACT:
Lamination of a tufted, primary carpet backing to a secondary backing is conducted using a composite hot melt adhesive in sheet form. The composite adhesive overcomes the unfavorable temperature-viscosity gradient within the carpet structure during the lamination process, yielding tufted pile carpets with good tuft encapsulation, tuft bind strength and delamination strength. Also disclosed are hot melt adhesive compositions suitable for use in sheet form in such a process.
