Elastic necked-bonded materials and methods of forming the same

摘要

A method of forming a stretchable composite by applying a polymeric precursor (26), such as a latex or thermoset elastomer, to a neckable material (12) either prior to or after neck-stretching the material, then treating the polymeric precursor (26) on the necked material to form a polymeric tie layer (27). An elastic sheet (32) is bonded to the tie layer and necked-stretched material thereby forming an elastic necked-bonded laminate (44).
