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.

Nonwoven abrasive articles and methods

A method of selectively applying pressure-sensitive adhesive to a nonwoven web and thereby forming a cleaning sheet having adhesive free peaks and adhesive containing valleys includes coating an adhesive transfer roll with adhesive, transferring a portion of the adhesive to raised regions of a female pattern forming roll, separating the adhesive between the adhesive transfer roll and the female pattern forming roll, and transferring the adhesive from the raised regions of the female pattern forming roll to the web. An apparatus for selectively applying pressure-sensitive adhesive to a nonwoven web and forming a cleaning sheet is also described.
