Abstract
The present invention is directed to an elastic laminate which is elastically extensible in at least one direction. The elastic laminate includes an elastomeric material having a first surface and a second surface opposing the first surface; and a first nonwoven layer joined to the first surface of the elastomeric material. The first nonwoven layer is formed from component fibers having a primary fiber direction. The first nonwoven layer has a Fiber Orientation Ratio within about ±20 degrees from a primary fiber direction of at least about 65%. The present invention is also directed to a disposable garment employing such an elastic laminate.
