  A,xiaomao fine leather
 
  Xiaomao fine leather strip shape most for tubular skin,a few for open piece of leather.Drum skin has two kinds:plate out after the file(or don't open rear bumper)drum skin and hair out after the file of the drum skin.
 
  (a)identification plate out drum skin quality identification method of the pile quality,mainly according to the wool to take off the change process,pedal show characteristics of dew,and in a small amount of the actual situation of external plush,plush to determine the length and density.This kind of skin easily found on the pedal various existing disability,can be directly according to the weight of the disabled,to judge the system the influence degree of the fur coat.And the hair in the drum skin wool in various defects in the inside of the skin tube,inspection is directly observed,this needs according to the disability in the pedal and part of the exposed wool characteristics reflect,to judge.Through the observation of the panel color variation,the strength of the light,listen to the voice of the pile friction and help to set the disability of the category,the character and degree.Such as the pedal local has become dark,water wet trace,show that the parts of the wool already by boring and fall off.
