Chitosan fiber has a wide range of applications and industry development is accelerating

Chitosan fiber is also called chitosan fiber and chitosan fiber. It is a fiber made by removing the acetyl group of chitin through concentrated alkali treatment. Chitosan fiber has the advantages of deodorization and deodorization, broad-spectrum antibacterial, good biocompatibility, strong adsorption, and biodegradability. It is widely used in medical materials, textiles, filter materials and other fields.

The main raw material of chitosan fiber is chitosan, and chitin is the main source of chitosan. my country is a major marine aquaculture country, with marine aquaculture area and aquatic product production ranking among the top in the world. Chitin can be extracted from shrimp and crab shells. In 2022, my country’s shrimp and crab shell production will reach 13 million tons, which lays a good foundation for the development of the chitin industry. . Chitosan is produced by removing the acetyl group of chitin through concentrated alkali treatment. It has natural antibacterial properties. Chitosan fiber made from it as raw material has the advantages of broad-spectrum antibacterial and good biocompatibility.

The main preparation methods of chitosan fiber include dry and wet spinning, wet spinning and electrospinning. Wet spinning refers to adding acetic acid aqueous solution to chitosan, and finally obtains chitosan fiber through processes such as dissolution, filtration, spinning, stretching, shaping, and drying; electrospinning refers to dissolving chitosan and The finished product is obtained through processes such as spinning, extrusion, and electrostatic stretching. The chitosan fiber produced by this method has the characteristics of good electrical conductivity, good mechanical properties, and small fiber diameter, and can be used to produce nanocomposite materials.

According to the “2023-2028 China Chitosan Fiber Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , Chitosan fiber has a wide range of applications. In the field of medical materials, chitosan fiber can be used to produce hemostatic materials, medical sutures, artificial skin, artificial dialysis membranes, etc.; in the field of textiles, chitosan fiber is an important raw material for quilt covers, pillow covers, blankets, towels and other products; In the field of filter materials, chitosan fiber has strong adsorption properties and can be used to produce tobacco filters.

There are many chitosan fiber manufacturers and the market competition is fierce. The world’s leading chitosan fiber companies include Japan’s Fujibo Co., Ltd., Japan’s Unitika Co., Ltd., South Korea’s Yingde Chitin Co., Ltd., and the United States’ DuPont Company, etc.; the main players in my country’s chitosan fiber market include Shandong Huaxing Textile Group Co., Ltd. , Suzhou Hengguang Chemical Fiber Co., Ltd., Shandong Hesmore Biotechnology Co., Ltd., Qingdao Tsunami Bioengineering Co., Ltd., Qingdao Jifa Group Co., Ltd., etc.

Industry analysts said that chitosan fiber has excellent performance and is widely used in many fields. With the continuous improvement of technological innovation level, the industry development The outlook will continue to improve. At present, Chinese companies have large-scale production capabilities of chitosan fiber, but there is still a gap in output compared with overseas developed countries. As the independent research and development capabilities of local enterprises continue to improve, the concentration of my country’s chitosan fiber industry will increase.
