Hybrid Abrasive Hand Pad and Method of Abrading a Surface

Abstract

An abrasive hand pad includes a coaled abrasive member secured to a nonwoven abrasive member. Methods of abrading a surface of a workpiece are also disclosed.

What is claimed is: 
     
         1 . A hybrid abrasive hand pad comprising:
 a coated abrasive member comprising an abrasive layer secured to a major surface of a flexible, dense backing, wherein the abrasive layer comprises first abrasive particles and a first binder; and   a nonwoven abrasive member secured to the backing opposite the abrasive layer, wherein the nonwoven abrasive member comprises second abrasive particles secured to a lofty open nonwoven fiber web by a second binder.   
     
     
         2 . The hybrid abrasive hand pad of  claim 1 , wherein the abrasive layer comprises a make layer, a size layer, and the first abrasive particles. 
     
     
         3 . The hybrid abrasive hand pad of  claim 1  wherein the abrasive layer comprises shaped abrasive composites comprising the first abrasive particles and the first binder. 
     
     
         4 . The hybrid abrasive hand pad of  claim 1 , wherein the coated abrasive member has a plurality of perforations extending through the abrasive layer and the backing. 
     
     
         5 . A method of abrading a surface of a workpiece, the method comprising frictionally contacting the hybrid abrasive hand pad of  claim 4  with the surface of the workpiece, and moving at least one of the abrasive hand pad or the workpiece to abrade the surface of the workpiece. 
     
     
         6 . A method of abrading a surface of a workpiece, the method comprising frictionally contacting the hybrid abrasive hand pad of  claim 1  with the surface of the workpiece, and moving at least one of the abrasive hand pad or the workpiece to abrade the surface of the workpiece.
