Abstract
An elastomeric laminated fabric which is elastic in the cross direction. The laminate includes an elastomeric film having one or two nonwoven webs of carded thermoplastic staple fibers thermally point bonded thereto using heated calendar rolls. The resulting laminated fabric is stretchable by at least 100% in the cross direction without breaking for at least two cycles and recovers elastically. The fiber content of the nonwoven webs is at least 50% high-elongation polyolefin staple fibers having a breaking strain of at least 400%.
