Description

technical field [0001] The invention relates to the technical field of raccoon fur bleaching, in particular to a method for bleaching and decolorizing raccoon fur fibers. Background technique [0002] Raccoon hair fiber is a precious textile raw material and a special animal fiber. The natural raccoon fur fiber is camel color and has the effects of light weight, softness and warmth. Its color is darker, which is not conducive to dyeing the required bright color or light color, so its application in the textile industry will be limited to a certain extent. The research on the bleaching and decolorization method of raccoon hair fiber is less at present, therefore, seeking the method for bleaching and decolorization of raccoon hair fiber and making it less damage to the fiber has become an important subject at present. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for bleaching and decolorizing raccoon ...
