摘要： 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.

摘要翻译： 提供了一种弹性非织造层压制品，其包含层叠在一个或多个非织造面层上的弹性膜。 非织造织物包含常规聚烯烃，并且还可以含有基于聚烯烃的塑性体。 通过切槽来激活层压板以将非织造材料面与弹性膜分离。 为了减少由于切槽激活而导致的光纤拉出，层压板可以在室温或高温下和特定压力范围内进行后粘合，以压紧面料的纤维并最大限度地减少纤维拉出/模糊性，而不会 牺牲层压板的柔软度，弹性和感觉。

摘要： Laminates are described that contain a frangible layer adhered to at least one extensible layer, such as an elastic layer. In one embodiment, a frangible layer is positioned between two opposing elastic layers. The frangible layer includes lines of separation that generally extend in a first direction. The lines of separation allow the elastic layers to stretch and recover in a direction perpendicular or skew to the lines of separation. In one particular embodiment, the lines of separation comprise lines where the frangible layer has been weakened. The lines of separation can be formed after the laminate is made using groove rolls.
摘要翻译： 描述了包含粘附到至少一个可延展层（例如弹性层）上的易碎层的层压体。 在一个实施例中，易碎层位于两个相对的弹性层之间。 易碎层包括通常沿第一方向延伸的分离线。 分离线允许弹性层在与分离线垂直或偏斜的方向上拉伸和恢复。 在一个特定实施例中，分离线包括易碎层已被削弱的线。 在使用槽辊制成层压体之后可以形成分离线。
