Bundle of hairs and manufacturing method for the same

Abstract

A bundle of hairs, having a hair portion which is composed of plural hairs of synthetic fiber and a base for connecting base ends of the plural hairs of the synthetic fiber, used for painting, writing, drawing, etc., with liquid impregnated into the bundle of hairs. A rate of synthetic fiber non-existent area to an area defined by dimensions of a base portion of the hair portion is set to correspond to purposes of the bundle.

What is claimed is:  
     
         1 . A bundle of hairs having a hair portion composed of plural synthetic fibers and a base mutually connecting base ends of the plural synthetic fibers, and used for painting, writing, drawing, etc., impregnated with liquid, comprising a ratio of synthetic fiber non-existent area to an area defined by dimensions of a base portion of the hair portion set as to correspond to purposes of the bundle.  
     
     
         2 . The bundle of hairs as set forth in  claim 1 , wherein the ratio of synthetic fiber non-existent area to the area defined by the dimensions of the base portion of the hair portion is 30% to 85%.  
     
     
         3 . The bundle of hairs as set forth in  claim 1  or  claim 2;  wherein the hair portion is composed of two or more kinds of synthetic fibers.  
     
     
         4 . The bundle of hairs as set forth in  claim 1  or  claim 2 , wherein diameter of the synthetic fiber disposed on a central area of a flat portion of the base is differentiated from diameter of the synthetic fiber disposed on peripheral area surrounding the central area.  
     
     
         5 . The bundle of hairs as set forth in  claim 1  or  claim 2 , wherein diameter of the synthetic fiber disposed on a central row area of a flat portion of the base is differentiated from diameter of the synthetic fiber disposed on side row area on the both sides of the central row area.  
     
     
         6 . The bundle of hairs as set forth in  claim 1  or  claim 2 , wherein a fluid flowing gap is formed on the base.  
     
     
         7 . A manufacturing method for bundle of hairs comprising the steps of: 
 preparing a fiber positioning member having plural through holes and inserting synthetic fibers to desired through holes among the plural through holes on the fiber positioning member;    connecting and bundling end portions of the synthetic fibers protruding from the fiber positioning member by melting or adhesion; and    drawing the synthetic fibers from the fiber positioning member and cutting the synthetic fibers into a predetermined length.    
     
     
         8 . The manufacturing method for bundle of hairs as set forth in  claim 7 , wherein protruding length of the synthetic fibers in the bundling step is short.  
     
     
         9 . The manufacturing method for bundle of hairs as set forth in  claim 7 , wherein protruding length of the synthetic fibers in the bundling step is sufficiently long.  
     
     
         10 . A manufacturing method for bundle of hairs comprising the steps of: 
 preparing a fiber positioning member having plural through holes and inserting synthetic fibers respectively to desired through holes among the plural through holes on the fiber positioning member;    connecting and bundling end portions of the synthetic fibers protruding from the fiber positioning member by melting or adhesion;    drawing the synthetic fibers from the fiber positioning member and cutting the synthetic fibers into a predetermined length; and    tapering forth ends of the synthetic fibers after the cutting.    
     
     
         11 . The manufacturing method for bundle of hairs as set forth in  claim 7 ,  8 ,  9 , or  10 , wherein the fiber positioning member is constructed as that a wavy concavo-convex flexible thin plate is wound as to form plural through holes.  
     
     
         12 . The manufacturing method for bundle of hairs as set forth in  claim 7 ,  8 ,  9 , or  10 , wherein two or more kinds of synthetic fibers are used.  
     
     
         13 . The manufacturing method for bundle of hairs as set forth in  claim 7 ,  8 ,  9 , or  10 , wherein diameter of the synthetic fiber inserted to the desired through hole of the fiber positioning member is differentiated from diameter of the synthetic fiber inserted to the other through holes surrounding the desired through hole.  
     
     
         14 . The manufacturing method for bundle of hairs as set forth in  claim 7 ,  8 ,  9 , or  10 , wherein diameter of the synthetic fiber inserted to the through holes in a desired row of the fiber positioning member is differentiated from diameter of the synthetic fiber inserted to the other through holes in both side rows on the both sides of the desired row.  
     
     
         15 . The manufacturing method for bundle of hairs as set forth in  claim 7 ,  8 ,  9 , or  10 , wherein two or more kinds of synthetic fibers having different diameters are inserted to one through hole of the fiber positioning member.  
     
     
         16 . The manufacturing method for bundle of hairs as set forth in  claim 7 ,  8 ,  9 , or  10 , wherein mutual interval between the through holes of the fiber positioning member is set to be 0.10 mm to 3.00 mm.
