Abraded spiral wound brush

Abstract

In a spiral wound brush for applying mascara and similar hair-streaking cosmetic products, the present invention replaces the sharply clipped ends common to the synthetic fibers typically employed with synthetic fibers having raggedly formed bristle ends for enhancing the pick up of the cosmetic product and for applying it thereafter with a softer feel.

1 . In a spiral wound brush for applying cosmetic products, the improvement comprising: 
 providing said brush with extruded synthetic fibers of like diameter along the lengths thereof having raggedly formed bristle ends for picking up the cosmetic product and for thereafter transferring same for application.    
   
   
       2 . The improvement of  claim 1  providing said brush with extruded synthetic fibers of like diameter along the lengths thereof having raggedly formed bristle ends for the picking up and subsequent transferring of one of mascara and hair-streaking cosmetic products.  
   
   
       3 . The improvement of  claim 1  wherein said brush is provided with one of hollow and solid extruded synthetic fibers.  
   
   
       4 . The improvement of  claim 1  wherein said brush is provided with one of hollow and solid extruded synthetic polymer fibers.  
   
   
       5 . The improvement of  claim 1  wherein said brush is provided with one of hollow and solid extruded synthetic polyamide fibers.  
   
   
       6 . The improvement of  claim 13  wherein said bristle ends are formed by a rotating cylindrical abrading wheel.  
   
   
       7 . (canceled)  
   
   
       8 . The improvement of  claim 13  wherein said abraded bristle ends are formed by a rotating cylindrical abrading wheel applying an abrasion force perpendicularly to the extruded synthetic fibers.  
   
   
       9 . The improvement of  claim 13  wherein said abraded bristle ends are formed by a rotating cylindrical abrading wheel applying an abrasion force laterally along the extruded synthetic fibers.  
   
   
       10 . The improvement of  claim 1  wherein said brush is provided with one of hollow and solid extruded synthetic fibers whose ends are subjected to one of organic and inorganic chemical exposure.  
   
   
       11 . The improvement of  claim 1  wherein said brush is provided with hollow extruded synthetic polyamide fibers.  
   
   
       12 . (canceled)  
   
   
       13 . In a spiral wound brush for applying cosmetic products, the improvement comprising: 
 providing said brush with extruded synthetic fibers of like diameter along the lengths thereof having raggedly formed, abraded bristle ends for picking up the cosmetic product and for thereafter transferring same for application.    
   
   
       14 . The improvement of  claim 13  providing said brush with extruded synthetic fibers of like diameter along the lengths thereof having raggedly formed, abraded bristle ends for the picking up and subsequent transferring of one of mascara and hair-streaking cosmetic products.
