Bristle is a traditional commodity that my country exports to earn foreign exchange. The export volume is large and the price is rising gradually. The processing is simple, does not require much investment and equipment, and can be done by ordinary families. It is a good way to get rich. The processing and collection methods are now introduced as follows: 1. Collecting and pulling the bristles 1. The method of pulling the bristles of live pigs. It is best to pull the bristles of live pigs in summer, when it is the time of hair removal and hair removal. 5 minutes before the first plucking, feed the pigs some vinasse-like feed to expand the pores of the pigs. Then, while the pigs are eating or lying still, touch the pig's body with one hand and pull the bristles with the other hand. Try to pull it off gently. If the hair roots are loose, it means that the extraction is the most timely. When it is judged that the hair roots are loose, you can use a fine wood comb to comb the pig's bristles from back to front. The bristles can be combed, put in a pre-prepared paper bag and stored. If the hair roots are not very loose, you can first use your thumb, index finger and middle finger to hold three or five bristles and pull upwards. Pull out once every 1-3 days. Do not pull too much each time until you finish pulling. In this way, as long as the hair is plucked in time, a 100 kg pig can extract 1 to 2 kg of bristles. Pulling the bristles of live pigs will not affect the normal growth and development of the pigs. Due to the stimulation of pulling the bristles, it can not only increase the appetite of the pigs, but also speed up the growth of fat. Matters needing attention: ①The piglet should be kept dry. To prevent skin infections caused by pulling the bristles. ②Don't pull too much at one time, it is better to use thin pull, less pull, do not pull the whole piece. It should be pulled out gradually, and then wait until the next time it grows up. ③Don't pull hard bristles that are not easy to pull out, to prevent the bristles from breaking or pulling the bristles together with the flesh and the skin. 2. The method of collecting bristles: ①. Double planing method. After killing the pig, scald the hemp pig's body with hot water, first use a nail brush to shave the sweat skin of the pig, and then use an iron shaver to shave off the pig hair. ②. In the separate slaughter method, at present, the price of black bristles is high, white bristles are the second time, and flower bristles are the second. When killing the pig, the action should be a little slower. Try to separate the black and white bristles. ③. Brushing method. Spring and autumn are the moulting seasons of live pigs. Iron combs can be used to scrape the whole body of pigs once every 3 days. This will not only make the pig hair fall off and be easy to collect, but also stimulate the growth of new hair in the cortex. It is suitable for male and female pigs. 2. The manual processing method of bristles. The bristles are processed by hand. The technology is simple. Generally, small and medium-sized enterprises and even families can perform operations. The method is as follows. 1. Process the raw materials into wool or mixed bristles to classify the pig hairs according to their hair color, and remove the belly hair, tail hair, mildew hair and sundries; The fur is scattered; after washing the loose pig hair with water, use an iron comb to remove the fluff, dander, etc. and wash it off; dry the clean hair and dry it into a fur shop, which can be sold. 2. The wool paving is made into a semi-finished product. The wool paving is tied with a rope to a small wooden board, and steamed in a pot to straighten the bent strip and increase the gloss, remove the fishy filth, and achieve the disinfection and sterilization effect. 3. To make the finished product, combs are used for combing and grading from root to tip, first long and then short: rub lightly with both palms, straighten the head and tail; after grading and bundle, match the bristles of all levels according to the regulations, and then use the comb to comb After the initial inspection and re-inspection, the roots will be ground, that is, they will be cleaned up with a wooden board and the protruding hairs will be cut off; the packaging should be carried out after the inspection is passed, and the packing should be neatly arranged, and each layer should be sprinkled with camphor powder to prevent pests. The standard weight is 50kg and 60kg. 3. Regardless of black or white bristles, as long as they fully meet the following quality standards, they can be classified as first-class products. Those who lack one or two items are classified as second-class products, and those lacking two or more are considered third-class products. 1. The quality standard of the black bristles: the color is pure black and shiny; no yellow hair tip: the hair root is thick; the fork tip is not deep; Impurities such as ash and slag. 2. The quality standard of white bristles: no yellow and black; less oily hair; the same as other quality standards of black bristles.
