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.本發明揭示一種在雙軸彈性非織造積層材中給予約束的方法，及該受約束之積層材本身，該方法包含提供含有至少一種熔紡彈性織物及至少一種可延長織物或薄膜之雙軸彈性非織造積層材；及至少或較佳地將該至少一種熔紡彈性織物的單獨一部份融合到該可延長織物之至少一者上以產生至少一個非彈性區。較合宜地，該至少一種熔紡彈性織物及至少一種可延長織物或薄膜係為雙軸彈性，並因為該至少一層的熔紡彈性體而稱之為“非織造”。該熔紡彈性織物可包含以聚烯烴為基礎之彈性體或彈性體與熱塑性塑膠的摻合物。
