Abstract: A nonwoven abrasive article includes: a lofty open nonwoven fiber web, an abrasive layer bonded to the lofty open nonwoven fiber web, and a peripheral antiloading composition disposed on the abrasive layer. The peripheral antiloading composition comprises at least 50 percent by weight of wax having a melting point onset of from 180° F. (82° C.) to 290° F. (143° C.). A method of abrading a workpiece using the nonwoven abrasive article is also disclosed.

Abstract: A method of transferring a shaped particle to a substrate includes providing a scrim of at least two elongate strands periodically joined together at flexible bond regions to form an array of apertures between the strands. The scrim is extended along at least one direction to increase the minimum dimension of the apertures. Shaped particles are applied to the extended scrim and at least a portion of the shaped particles enter in at least some of the apertures therein. The extended scrim is relaxed and frictionally retains the particles between the elongate strands. The particle loaded scrim is extended along at least one direction to release and transfer the shaped particles to the substrate in a predetermined orientation.
