ELASTIC LAMINATES WITH IMPROVED HYSTERESIS

摘要

PURPOSE: Nonwoven fabric or web laminates which contain at least one elastic layer and which are formed from fibers, films, fiber arrays and the like, are provided. CONSTITUTION: A composite elastic material laminate having improved hysteresis comprises a layer of an elastic material bonded to a layer of nonelastic material on at least one side, wherein the elastic material layer comprises a blend of a narrow polydispersity number polymer and a conventional elastomer and wherein the blend is essentially free of low molecular weight polyethylene processing aids.
