Cloth-like biaxial stretch nonwoven
摘要：
An elastomeric composite web (20) includes an elastomeric-substrate (22), and an operative layer of an elastomeric polypropylene-based adhesive material (24) or other surface modifying agent which is adhered or otherwise applied directly to at least one major, facing-side (26) of the elastomeric-substrate (22). In particular aspects, the layer of the surface modifying agent (24) has been provided separate from the elastomeric-substrate (22), and the layer of surface modifying agent (24) has been applied directly to the elastomeric-substrate (22) while the elastomeric-substrate has been operatively configured in a substantially unstretched condition. In other aspects, the elastomeric-substrate (22) can have a distinctively high basis weight, and the layer of surface modifying agent (24) can be applied directly to the elastomeric-substrate (22) prior to attaching the elastomeric-substrate to any separately provided, substantially non-elastomeric, supplemental-substrate. In a further aspect, the elastomeric-substrate (22) can be substantially free of continuous, elastomeric strands.
摘要（中）：

弹性体复合网（20）包括弹性体基底（22），以及弹性体聚丙烯基粘合剂材料（24）或其它表面改性剂的操作层，其粘附或以其他方式直接施加到至少一个主要面 （26）的弹性体基底（26）。 在特定方面，表面改性剂（24）的层已经与弹性体基材（22）分开提供，并且表面改性剂层（24）已被直接施加到弹性体基材（22），同时 弹性体基底已被可操作地构造成基本上未拉伸的状态。 在其它方面，弹性体基材（22）可以具有明显高的基重，并且在将弹性体基材连接到任何材料之前，可以将表面改性剂层（24）直接施加到弹性体基材（22） 单独提供，基本上非弹性的补充基底。 在另一方面，弹性体基材（22）可以基本上不含连续的弹性体股线。
