Method for preparing writing brush hair from animal fur waste

Abstract

The invention provides a method for preparing writing brush hair from animal fur waste. The method comprises the following steps of (1) conducting color separation, screening and impurity removal on the animal fur waste; (2) cleaning the pretreated animal fur through aerial fog spray-washing and conducting vacuum drying on the animal fur; (3) adding the cleaned animal fur into compound alkaline liquor for treatment at 60-80 DEG C for 2-4 h, adjusting the PH to be 7, conducting filtering immediately to obtain blank hair, and then conducting washing and drying on the blank hair; (4) adding the blank hair into a dye solution for dyeing at 50-70 DEG C for 3-5 h, then adding tryptophan and a color fixing agent, keeping heat preservation treatment for 30 min, adjusting the PH to be 7, and taking out, washing and drying the blank hair; (5) conducting ageing; and (6) conducting high-temperature cooking and softening. According to the method, an animal fur leftover material is adopted as a raw material for production of writing brush hair; resources can be repeatedly utilized; the production cost is lowered; and a manufactured writing brush is fluent in writing, high in degreasing degree and large in ink absorption amount.

Description

technical field [0001] The invention belongs to the technical field of brush processing, in particular to a method for preparing brush hair, in particular to a method for preparing brush hair from animal fur waste. Background technique [0002] The pen made of poultry, animal or human hair is listed as one of the four treasures of the study in China, which is divided into hard, double and soft. The raw materials for making brush tips are mainly wool, weasel tail hair, mountain rabbit hair, stone badger hair, and beaver hair. Pig palm and workers are also widely used in making brush tips. . Brush shafts are mostly made of bamboo tubes, such as green bamboo (roasted red), purple bamboo, mottled bamboo (Xiangfei bamboo), Luohan bamboo, etc., and mahogany, horn, aggregate, ivory, and jade are also used as shafts, which are more luxurious.

Problems solved by technology

[0003] Usually, people obtain the raw materials of brush brush hair from regular cutting, which usually results in the incomplete utilization of the residual hair on animal skins. However, the production of animals in my country is limited, and the source of animal hair is limited, so the existing resources are efficiently used. It is a major problem in the brush hair processing technology
