Chitin fiber has a wide range of applications and the development trend of industrial clustering is obvious.

Chitin fiber, also known as chitin fiber, refers to fiber materials made from chitin and its derivative chitosan as raw materials through spinning. Compared with traditional cotton fiber, chitin fiber has the characteristics of strong hygroscopicity, good antibacterial properties, good air permeability, and can inhibit parasites. It is widely used in many fields such as bedding, clothing, medical and health care.

The main raw materials of chitin fiber are chitin and chitosan, and shrimp and crab shells are the main sources of raw materials. Our country has a vast territory, a huge marine aquaculture area, and a rich variety of aquatic products, which has driven the continuous growth of shrimp and crab shell production. In 2022, my country’s shrimp and crab shell production will reach nearly 13 million tons, setting a record high. The chitin content in shrimp and crab shells reaches nearly 90%. Benefiting from the sufficient supply of raw materials, my country’s chitin production continues to increase, laying a good foundation for the development of the chitin fiber industry.

The main preparation methods of chitin fiber include indirect production method, wet spinning method and fermentation method. The indirect production method is usually used to produce regenerated chitin fiber. It first uses chitin to produce chitosan, then dissolves, dilutes, precipitates and other processes to obtain chitosan fiber, and finally adds acetyl group to obtain the finished product; wet spinning method It is a traditional preparation method for chitin fiber. It first makes chitin into an organic solution, and then goes through processes such as filtration, spinning, drawing, washing, and drying to obtain finished products. The fermentation method has low operating costs and can be used for large-scale production and production. With the advantages of simple process, it is expected to become the mainstream preparation method of chitin fiber in the future.

According to the “2023-2028 China Chitin Fiber Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, Chitin fiber is a natural regenerated cellulose fiber that is widely used in bedding, clothing, medical and health care and many other fields. In the field of clothing, chitin fiber can be used to produce sportswear, antibacterial underwear, antibacterial socks, shirts, etc.; in the field of medical and health care, chitin fiber can be used to prepare medical sutures, artificial skin, medical dressings, hemodialysis membranes, and sustained-release drugs. Agents, etc.

Chitin fiber is an antibacterial fiber. Attracted by market prospects, the number of companies entering the chitin fiber industry in my country is increasing. Qingdao Jifa Group, Shandong Xinke Marine Biology, Weifang Yingde Chitin, etc. are the main players in my country’s chitin fiber market. At present, the clustering trend of my country’s chitin fiber industry is relatively obvious, and Shandong is the region with the largest number of enterprises in my country.

Industry analysts said that chitin fiber has the advantages of strong hygroscopicity and good antibacterial properties, and is widely used in many fields. As market demand is gradually released, the development prospects of the industry will continue to improve. my country’s chitin output is relatively high, and its raw material advantages provide favorable conditions for the development of the chitin fiber industry. At present, my country’s chitin fiber companies are concentrated in Shandong, with a high degree of industrial aggregation.
