       7 . The dusting article of  claim 1 , where the first fiber layer and the second fiber layer comprise fibers comprising a fineness of 1 to 50 dtex.  
   
   
       8 . A dusting article comprising: 
 a base sheet;    a second base sheet adjacent to the base sheet;    a first fiber layer adjacent to the second base sheet;    a first sheet adjacent to the first fiber layer;    a second fiber layer adjacent to the first sheet;    a supplemental fiber layer attached to the second fiber layer; and    a second sheet adjacent to the supplemental fiber layer.    
   
   
       9 . The dusting article of  claim 8 , wherein said base sheet comprises thermoplastic fibers.  
   
   
       10 . The dusting article of  claim 9 , wherein said thermoplastic fibers comprise fibers of polyethylene, polypropylene, polyethylene terephthalate; conjugated fibers of polyethylene and polyethylene terephthalate or polyethylene and polypropylene and combinations thereof.  
   
   
       11 . The dusting article of  claim 8 , wherein the first fiber layer and the second fiber layer comprise crimped fibers.  
   
   
       12 . The dusting article of  claim 8 , wherein at least one of the base sheet, second base sheet, first sheet and the second sheet are cut into strips.  
   
   
       13 . The dusting article of  claim 12 , wherein the strips are from about 1 mm to about 15 mm wide.  
   
   
       14 . The dusting article of  claim 8 , where the first fiber layer, the second fiber layer, and the supplemental fiber layer comprise fibers comprising a fineness of 1 to 50 dtex.
