Pig bristles are one of the important raw materials for brush making, and most paint brushes are processed from bristles. At present, the quality requirements of my country's supply and marketing system for the purchase of raw bristles are: white, black, and yellow, with separate colors, no impurities, no mold, and drying. They are purchased in 8 grades. According to the current production methods of bristles in rural areas, its processing and finishing can be divided into three stages. 1. Processed from raw materials into hair shop 　 　 classify the bristles according to their hair color, remove impurities, and then place them in warm water at 45-60°C to moisten and ferment for a whole day and night to soften the residual meat and grease contained in the bristles. Remove the fermented and moist bristles from the water, pound the skin with a wooden board to make it completely separate and loosen from the sticky bristles. After washing with water, use iron and sulfur to comb away the fluff, dander, etc. Wash the bristles several times with clean water. Put the cleaned bristles on a bamboo sieve and place them on a kang stove to dry them or place them in the sun to dry them. The dried bristles will become a 'hair shop'.

The finished product is made of semi-finished products. The pig bristles are tied with hemp rope, and the long bristles are removed with sulphur. The head and tail are straightened out, and the roots are tied with jute rope to form a strong original handle according to various specifications and sizes. The original bundled handles must be carefully inspected to see if there is any shedding dander, and the tips are trimmed, and then inspected for mildew, miscellaneous hair and oily hair, etc., if necessary, use tweezers to pick it out.

The packaging box should be dry, lined with a layer of oiled paper, and then covered with a layer of white paper to prevent moisture and rain from entering. Each layer should be sprinkled with camphor powder (300-400 grams per box) to prevent insects.
