The research on irradiation preservation technology of animal products has been more than 40 years old and has proved to be a new technology with high safety, reliability and high economic efficiency. Some foreign countries have entered the practical stage. China has approved 7 kinds of irradiated foods such as rice and peanuts for sale.　　

Xinjiang is one of the five largest pastoral areas in the country, and its livestock resources are very rich. The animal hair processing products such as labor insurance, thermal insulation, industrial and civilian felts are the main livestock products in Xinjiang. The annual savings are about 80,000, and the variety is wide and the texture is pure and exported to all parts of the country.

However, during the midsummer (May to September) preservation, felts and other hair products are often endangered by worms, quality is damaged, and losses are caused. The fact that goods cannot be stored in summer is a problem that has been difficult to solve for a long time. General warehouses use chemical fumigants to spray and kill, but the effect is not ideal. According to reports, some chemical fumigants can cause cancer in animals, and many countries in the world have banned their use. In addition, the felt production process is extensive, and the amount of bacteria is large, which also affects human health. Therefore, we have carried out research on felt irradiation sterilization technology, providing scientific basis for using radiation instead of chemical fumigation.
