<p>A base substrate (100) having a first side (110) and a second side (120), first and second receiving loops (210, 220) extending from the first and second sides of the base substrate, respectively, and first and second stiff loops (310, 320) extending from the first and second side of the base substrate, respectively. The base substrate is a flexible cloth or cloth-like material. The receiving loops are an absorbent material such as the material used in the base substrate. The stiff loops are formed of a yarn having at least one filament with a cross-section having an aspect ratio of greater than about 1.2, a corner edge, and/or at least a concave portion.</p> |
