    • A single- or multi-ply disposable wiping article is disclosed. The disposable wiping article comprises at least one web layer and has a surface topography exhibiting regions of minimum and maximum calipers. A continuous polymer network defining bonded regions and a plurality of unbonded regions is bonded to the web layer. The continuous polymer network is preferably a thermoplastic adhesive. After curing, the thermoplastic adhesive can contract upon heating, thereby creating puckered regions of maximum caliper coincident unbonded regions. The minimum caliper of the web layer is coincident the bonded regions. Methods of making the web of the present invention are disclosed. One method includes providing a first web layer; providing a thermoplastic adhesive; applying the thermoplastic adhesive to the first web layer in a continuous network; curing the thermoplastic adhesive; and heating the thermoplastic adhesive to effect contraction of the thermoplastic adhesive.
    • 公开了单层或多层一次性擦拭物品。 一次性擦拭制品包括至少一个纤维网层并且具有表现出最小和最大卡尺的区域的表面形貌。 限定结合区域和多个未结合区域的连续聚合物网络被结合到网状物层。 连续聚合物网络优选为热塑性粘合剂。 固化后,热塑性粘合剂可以在加热时收缩,从而产生最大卡尺一致的未粘合区域的褶皱区域。 纤维网层的最小厚度与接合区域重合。 公开了制造本发明的网的方法。 一种方法包括提供第一网层; 提供热塑性粘合剂; 在连续的网络中将热塑性粘合剂施加到第一纤维网层; 固化热塑性粘合剂; 并加热热塑性粘合剂以实现热塑性粘合剂的收缩。
