发明名称 CLEANING WIPE WITH VARIABLE LOFT WORKING SURFACE
摘要 <p>A cleaning wipe (20) useful as a wet cleaning wipe for picking up diverse debris, such as hair and other debris such as dirt, including a web (22) defining a working surface (24) opposite a second surface (36). The working surface(24) has first(30), second (32), and third(34) regions each having a different degree of loftiness and a different height. The degree of loftiness of the first region (30) is greater than that of the second (32) and third (34) regions, and the degree of loftiness of the second region (32) is greater than that of the third region (34). Finer debris, such as wetted hair, is captured and/or retained within the first region (30), whereas other debris such as particulates (e.g., dirt, sand) are captured and/or retained in the second region(32). In one embodiment, a plurality of the first(30), second(32), and third (34) regions are defined on the working surface (24) in a pattern.</p>
