摘要： Multilayer microporous films comprise first and second microporous film layers. The first film layer has a first maximum pore size and the second film layer has a second maximum pore size different from the first maximum pore size. In a more specific embodiment, the multilayer microporous films comprise coextruded first, second and third microporous film layers. One of the first, second and third film layers has a maximum pore size smaller than the respective maximum pore sizes of the remaining layers of the multilayer film or larger than the respective maximum pore sizes of the remaining layers of the multilayer film, and the one layer does not have an unconstrained surface in the multilayer film. Methods for producing multilayer microporous films provide a first film layer having a maximum pore size upon stretching which is different from that of a second film layer upon stretching.

摘要： The method and apparatus prevent the formation of pin-holes or other breakage during stretching of polymeric films, non-woven fibrous webs or laminates in the cross machine direction. Pin-holes and other breakage are prevented by creating slack areas along the length of the product where the edges of the non-woven strips meet with the polymer film, pressing the slack areas into the interdigital stretching rollers without stretching the slack areas, and stretching the remainder of the web in a typical manner. The slack regions are formed prior to interdigitation by, for example, formation of a furrow, a fold or a corrugation.
摘要翻译：该方法和装置防止在横向拉伸聚合物薄膜，非织造纤维网或层压板的过程中形成针孔或其它断裂。通过在产品的长度上产生松散的区域来防止针孔等破损，其中无纺布条的边缘与聚合物膜相遇，将松弛区域压入叉指拉伸辊而不拉伸松弛区域，并且拉伸网络的其余部分是典型的方式。松散区域通过例如沟槽，褶皱或波纹的形成在交叉之前形成。

摘要： The present invention is directed to a method and apparatus for in-line separation of polymer film and non-woven to compensate for the increased width due to stretching in the cross-machine (CD) direction. Due to the stretching in the cross-machine direction, typically by interdigital rolling or tentering, the width of individual webs is increased. To compensate for the increase in width, the apparatus and method of the present invention is employed to provide for in-line separation of the narrow webs. The apparatus of the present invention may allow for simplicity in threading the device, due to the ability to automatically thread individual turning bars by moving the turning bars across the undeflected path of the web.
摘要翻译：本发明涉及一种用于在线分离聚合物膜和无纺织物以补偿由于在跨机器（CD）方向上的拉伸而增加的宽度的方法和装置。由于横跨机器方向的拉伸，通常是通过叉指滚动或拉幅，每个腹板的宽度增加。为了补偿宽度的增加，本发明的装置和方法用于提供窄幅网的在线分离。本发明的装置可以允许在穿过装置时的简单性，这是由于通过将转动杆移动穿过幅材的未偏转路径来自动地螺纹连接各个转动杆的能力。

摘要： Microporous film products permeable to moisture vapor and which act as barriers to liquid are made by a high speed method. Such microporous products are made at speeds in the order of above 500 fpm to about 1200 fpm. Thermoplastic polymers are melt blended to contain about 35% to about 45% by weight of a linear low density polyethylene, about 3% to about 10% by weight of a low density polyethylene; about 40% to about 55% by weight calcium carbonate filler particles, and about 2% to about 6% by weight of a triblock polymer of styrene.

A web of spun bonded fibers is incrementally stretched to provide fiber ends extending outwardly from both web surfaces for bonding with the extruded thermoplastic film and to provide a soft fibrous texture to the laminate.
