Patent ID: 6878647

Claim:
An elastic laminate elastically extensible in at least one direction, comprising: (a) an elastomeric layer having a first surface and a second surface opposing the first surface; wherein the elastomeric layer is in a form selected from the group consisting of a scrim, an apertures formed film, an elastomeric woven or nonwoven, discrete strands and strings; wherein the elastomeric woven or nonwoven and discrete strand and strings comprise a polystyrene thermoplastic elastomer selected from the group consisting of a styrene-butadiene-styrene thermoplastic elastomer, a styrene-isoprene-styrene thermoplastic elastomer, a styrene-ethylene/butylene-styrene thermoplastic elastomer, a styrene-ethylene/propylene-styrene thermoplastic elastomer, a styrene-ethylene/propylene thermoplastic elastomer, a hydrogenated styrene butadiene rubber, and a mixture thereof; and (b) a first nonwoven layer joined to the first surface of the elastomeric layer, the first nonwoven layer being formed from component fibers having a primary fiber direction; wherein the first nonwoven layer has a Fiber Orientation Ratio within about ±20 degrees from a primary fiber direction of at least about 65%; wherein the elastic laminate exhibits elasticity without mechanical stretching of the first nonwoven layer during manufacture.
