Zusammenfassung:Disclosed is a method of imparting constraint in a biaxially elastic nonwoven laminate, and the constrained laminate itself, the method comprising providing a biaxially elastic nonwoven laminate comprising at least one meltspun elastic fabric and at least one extensible fabric or film; and fusing at least, or preferably, only a portion(s) of the at least one meltspun elastic fabric to at least one of the extensible fabrics to create at least one inelastic zone. Desirably, the at least one meltspun elastic fabric and at least one extensible fabric or film is biaxially elastic, and referred to as being "nonwoven" due to the at least one layer of meltspun elastomer. The meltspun elastic fabric may comprise a polyolefin-based elastomer or blend of an elastomer with a thermoplastic.
