    摘要： The present invention is directed to a pattern-unbonded nonwoven fabric having continuous bonded areas defining a plurality of discrete unbonded areas, which is suitable for use as an improved loop fastening material for hook and loop fastening systems. The fibers or filaments within the discrete unbonded areas of the present invention are dimensionally stabilized by the continuous bonded areas that encircle or surround each unbonded area. The spaces between fibers or filaments within the unbonded areas remain sufficiently open or large to receive and engage hook elements of a complementary hook material. The hook material can be any of a wide variety of commercially available hook components which, as is known in the art, typically include a base material from which a plurality of hook elements project. The present invention further is directed to a process for making such a pattern-unbonded nonwoven fabric including the steps of providing a nonwoven fabric or web, providing opposedly positioned first and second calender rolls and defining a nip therebetween, with at least one of said rolls being heated and having a bonding pattern on its outermost surface comprising a continuous pattern of land areas defining a plurality of discrete openings, apertures or holes, and passing the nonwoven fabric or web within the nip formed by said rolls.

    摘要翻译： 本发明涉及一种具有限定多个离散的未粘合区域的连续粘合区域的图案无粘合无纺织物，其适合用作钩和环紧固系统的改进的环形紧固材料。 在本发明的离散的未粘合区域内的纤维或细丝通过围绕或围绕每个未粘结区域的连续粘结区域尺寸稳定。 未粘合区域内的纤维或细丝之间的空间保持足够的开放或大的接纳和接合互补钩材料的钩形元件。 钩材料可以是各种可商购的钩部件中的任一种，如本领域已知的那样，钩部件通常包括多个钩元件从中突出的基材。 本发明还涉及一种制造这种图案无粘合无纺织物的方法，包括以下步骤：提供无纺布或网状物，提供相对定位的第一和第二压延辊并在其间限定一个辊隙，至少一个所述辊 被加热并且在其最外表面上具有粘合图案，其包括限定多个离散开口，孔或孔的接合区域的连续图案，并且将非织造织物或纤维网通过由所述辊形成的辊隙。
