Abstract
An abrasive sheet member is disclosed, including a substrate having first and second major surfaces, an abrasive on the first major surface, and a plurality of hooking stems on the second major surface. The hooking stems are adapted to hook engaging structures on an opposed surface to releasably affix the abrasive sheet member to the surface.
Claims22
An abrasive article for releasable affixation to an opposed surface having engaging structures, comprising:
- a) a substrate having first and second major surfaces;
- b) abrasive means disposed on the first surface;
- and
- c) a plurality of hooking stems integrally provided on and projecting from the second surface, the hooking stems each including means for hooking the engaging structures to releasably affix the abrasive article to the opposed surface, wherein;
- the hooking means are oriented randomly relative to an adjacent hooking means;
- and
- the substrate and the hooking stems are made from an organic thermoplastic polymeric material selected from the group consisting of polyurethanes, polyamides, polyolefins, polyesters, and combinations thereof.
