    摘要： The present invention is directed to a fluid-entangled laminate web and the process and apparatus for its formation as well as end uses for the fluid-entangled laminate web. The laminate web includes a support layer and a nonwoven projection web having a plurality of projections which are preferably hollow. As a result of the fluid-entangling process, entangling fluid is directed through the support layer and into the projection web which is situated on a forming surface. The force of the entangling fluid causes the two layers to be joined to one another and the fluid causes a portion of the fibers in the projection web to be forced into openings present in the forming surface thereby forming the hollow projections. The resultant laminate has a number of uses including, but not limited to, both wet and dry wiping materials, as well as incorporation into various portions of personal care absorbent articles and use in packaging especially food packaging where fluid control is an issue.

    摘要翻译： 本发明涉及流体缠结层压纤维网及其形成的方法和装置以及流体缠结的层压纤维网的最终用途。 层压纤维网包括支撑层和具有多个突起的非织造突起网，优选为中空的。 作为流体缠结过程的结果，缠结流体被引导通过支撑层并进入位于成形表面上的凸起网。 缠结液体的力导致两层彼此接合，并且流体使得突出腹板中的纤维的一部分被迫进入成形表面中的开口，从而形成中空突起。 所得到的层压板具有许多用途，包括但不限于湿擦拭和干擦拭材料，以及并入个人护理吸收制品的各个部分中，并且用于包装，特别是在流体控制是问题的食品包装中。
