Method to measure and/or adjust combing resistance by using a brush

Abstract

Disclosed herein is a method to measure and/or adjust combing resistance of fibers by using a brush, wherein the brush comprises: a brush handle; a brush head connecting to the brush handle and comprising a substrate and bristles which are mounted on the substrate, wherein a certain number of the bristles are movable; an activation means which moves the movable bristles from their original positions to different positions; wherein the brush further comprises at least one of the following: a cover for the brush head which is movable between an open position and a closed position, which internal surface can closely face to the tips of the bristles in its closed position, and which has a gap between the substrate and its side ends in its closed position; an indication to match at least one position of the movable bristles to at least one fiber type and/or at least one treatment type; or the combination thereof. By the use of the above brush device, it becomes easier to measure and/or adjust combing resistance of a variety of fiber types.

What is claimed is: 
     
         1 . A method to measure and/or adjust combing resistance of fibers by using a brush, wherein the brush comprises:
 a brush handle;   a brush head connecting to the brush handle and comprising a substrate and bristles which are mounted on the substrate, and wherein a certain number of the bristles are movable;   an activation means which moves the movable bristles from their original positions to different positions; and   a cover for the brush head which is movable between an open position and a closed position, which internal surface can closely face to the tips of the bristles in its closed position, and which has a gap between the substrate and its side ends in its closed position.   
     
     
         2 . A method to measure and/or adjust combing resistance of fibers by using a brush, wherein the brush comprises:
 a brush handle;   a brush head connecting to the brush handle and comprising a substrate and bristles which are mounted on the substrate, and wherein a certain number of the bristles are movable;   an activation means which moves the movable bristles from their original positions to different positions; and   an indication to match at least one position of the movable bristles to at least one fiber type and/or at least one treatment type.   
     
     
         3 . A method to measure and/or adjust combing resistance of fibers by using a brush, wherein the brush comprises:
 a brush handle;   a brush head connecting to the brush handle and comprising a substrate and bristles which are mounted on the substrate, and wherein a certain number of the bristles are movable;   an activation means which moves the movable bristles from their original positions to different positions;   a cover for the brush head which is movable between an open position and a closed position, which internal surface can closely face to the tips of the bristles in its closed position, and which has a gap between the substrate and its side ends in its closed position; and   an indication to match at least one position of the movable bristles to at least one fiber type and/or at least one treatment type.   
     
     
         4 . The method of any of  claims 1 - 3 , comprising the steps of:
 providing a sample of fibers;   placing the sample of fiber on the substrate and bristles of the brush;   moving the movable bristles by the activation means;   measuring and/or adjusting the combing resistance of the samples by brushing the samples by the brush.   
     
     
         5 . The method of  claim 1  or  3 , comprising the steps of:
 providing a sample of fibers; 
 placing the sample of fiber on the substrate and bristles of the brush when the cover for brush head is in an open position; 
 moving the cover to its closed position; 
 measuring the combing resistance of the samples by brushing the samples by the brush. 
 
     
     
         6 . The method of  claim 2  or  3 , comprising the steps of:
 providing a sample of fibers; 
 placing the sample of fiber on the substrate and bristles of the brush; 
 moving the movable bristles by the activation means according to the indication; 
 measuring and/or adjusting the combing resistance of the samples by brushing the samples by the brush. 
 
     
     
         7 . The method of any of  claims 1 - 3 , wherein the activation means moves the movable bristles to at least two different positions from the original position. 
     
     
         8 . The method of  claim 1  or  3 , wherein the gap between the substrate and the side ends of the cover is from about 20 mm to about 1 mm. 
     
     
         9 . The method of  claim 8 , wherein the gap between the substrate and the side ends of the cover is from about 10 mm to about 2 mm. 
     
     
         10 . The method of  claim 8 , wherein the gap between the substrate and the side ends of the cover is from about 5 mm to about 3 mm 
     
     
         11 . The method of any of  claims 1 - 3 , wherein the fiber is natural or artificial human hair. 
     
     
         12 . The method of any of  claims 1 - 3 , comprising the steps of:
 providing at least two different samples of fibers;   measuring the combing resistance of the samples by brushing the samples by the brush;   comparing the combing resistances of the samples.   
     
     
         13 . The method of  claim 12 , wherein one sample comprises untreated fiber(s) and the other sample comprises fiber(s) treated with a cosmetic, chemical and/or mechanical treatment. 
     
     
         14 . The method of  claim 12 , wherein the samples are treated with different cosmetic, chemical, and/or mechanical treatments. 
     
     
         15 . The method of  claim 12 , further comprising the step of utilizing said comparison to support advertising claims about the efficacy of a treatment. 
     
     
         16 . A brush of any of  claims 1 - 3 .
