Abstract
Nonwoven abrasive articles, particularly lofty nonwoven abrasive articles, with a textured, non-planar surface and an abrasive coating thereon. The coating may cover the entire surface or only portions of the surface. The textured surface, composed of peaks or high regions and valleys or recessed regions, provides improved cut performance over nonwoven abrasive articles having a generally planar abrading surface.
