Post-Bonded Grooved Elastic Materials

An elastic nonwoven laminate that contains an elastic film laminated to one or more nonwoven facings is provided. The nonwoven facing contains a conventional polyolefin and can also contain a polyolefin-based plastomer. The laminate is activated by grooving to decouple the nonwoven facing from the elastic film. To reduce fiber-pull out that can result due to activation by grooving, the laminate can be post-bonded at room or elevated temperatures and a specific range of pressures to compact the fibers of the facing and minimize fiber pull- out/fuzziness while not sacrificing the softness, elasticity, and feel of the laminate. 本发明提供了种弹性非织造层合物，所述弹性非织造层合物包括层合到个或多个非织造面料的弹性膜。所述非织造面料包含常规聚烯烃并且还可以包含基于聚烯烃的塑性体。所述层合物通过形成凹槽而激活以使所述非织造面料与所述弹性膜分离。为了减少可因形成凹槽而导致的激活所产生的纤维拉出，所述层合物可在室温或升高的温度和特定范围的压力下进行后粘结，以压实所述面料的所述纤维并最大程度减少纤维拉出/起绒毛性，而不牺牲所述层合物的柔软性、弹性和感觉。
