Brush and rotating brush

Abstract

A brush and a rotating brush are provided that are capable of flexibly setting the balance between scraping performance and mopping performance. The brush of the rotating brush includes a fabric base, which is formed by weaving warp and weft, and a brush portion, which includes bristles. The bristles are formed by pile yarns, which are woven into the fabric base to project upright from the outer surface of the fabric base. The bristles of the brush portion include two types of pile yarns that have different lengths and are arranged to be adjacent to each other in a warp direction, which is a direction in which the warp extends.

1 . A brush, comprising:
 a fabric base formed by weaving warp and weft; and   a brush portion that includes bristles, which are formed by pile, the pile being woven into the fabric base to project upright from an outer surface of the fabric base,   wherein the brush portion includes two or more types of the bristles between which at least one of a length, a diameter, or a density is different, the two or more types of the bristles being arranged to be adjacent to each other in a direction in which the warp extends.   
     
     
         2 . The brush according to  claim 1 , wherein the two or more types of the bristles between which at least one of the length, the diameter, or the density is different are adjacent to each other in a direction in which the weft extends. 
     
     
         3 . The brush according to  claim 1 , wherein
 the brush portion includes
 a first section that includes first bristles, and 
 second sections that include second bristles, at least one of a length, a diameter, or a density of the second bristles being different from that of the first bristles, and 
   the second sections are adjacent to opposite sides of the first section in the direction in which the warp extends.   
     
     
         4 . The brush according to  claim 2 , wherein
 the brush portion includes
 a first section that includes first bristles, and 
 second sections that include second bristles, at least one of a length, a diameter, or a density of the second bristles being different from that of the first bristles, and 
   the second sections are adjacent to opposite sides of the first section in the direction in which the weft extends.   
     
     
         5 . The brush according to  claim 3 , wherein the first bristles are shorter than the second bristles. 
     
     
         6 . The brush according to  claim 1 , wherein the fabric base and the pile are formed by jacquard weaving. 
     
     
         7 . A rotating brush, comprising:
 a rotor; and   the brush according to  claim 1 , the brush being arranged on an outer surface of the rotor.   
     
     
         8 . The brush according to  claim 3 , wherein the second sections are adjacent to opposite sides of the first section in the direction in which the weft extends. 
     
     
         9 . The brush according to  claim 4 , wherein the first bristles are shorter than the second bristles. 
     
     
         10 . The brush according to  claim 8 , wherein the first bristles are shorter than the second bristles. 
     
     
         11 . The brush according to  claim 1 , further comprising a constant clearance in which the bristles do not exist. 
     
     
         12 . The brush according to  claim 1 , wherein the fabric base is one continuous piece of fabric. 
     
     
         13 . The brush according to  claim 12 , wherein the fabric base and the pile are formed by jacquard weaving.
