Chemical fibers, also known as synthetic fibers, are fibers with textile properties made from natural or artificially synthesized polymer compounds through processes such as spinning solution preparation, spinning, and post-treatment. Chemical fibers have the characteristics of wear resistance, light resistance, easy washing and drying, and are not susceptible to insect damage. They can be used to manufacture products such as clothing, shoes, hats, conveyor belts, tire curtains, parachutes, and electrical insulation wires. They are applied in textile, transportation, automotive, construction, medical and other fields, among which the textile industry is the main application area of chemical fibers in China. According to the "2022-2026 Development Prospects and Investment Risk Avoidance Suggestions Report of China's Chemical Fiber Industry" released by the New World Industry Research Center, thanks to the progress of production technology and the increase in market demand, the production scale of China's chemical fiber industry continues to expand. According to data from the National Bureau of Statistics, from 2017 to 2020, the output of China's chemical fiber industry increased from 48.7705 million tons to 61.2468 million tons. The production scale of chemical fibers in China continues to expand, and it is expected to exceed 66.5 million tons in 2021.

Chemical fibers can be divided into synthetic fibers and synthetic fibers. Synthetic fibers are made from natural polymer compounds and are further divided into products such as viscose fibers, acetate fibers, nitrate fibers, etc; Synthetic fibers are made from artificial polymer compounds as raw materials, and are subdivided into products such as polyester fibers, polyacrylonitrile fibers, polyvinyl alcohol fibers, and specialty fibers. In recent years, in order to meet the diversified and high-end demands of the market, the speed of structural adjustment and technological innovation in China's chemical fiber industry has accelerated, and outdated production capacity has accelerated its exit from the market. The profitability of the chemical fiber industry has gradually improved.

China is a major producer of chemical fibers worldwide, accounting for approximately 70% of the total global production. The concentration of chemical fiber production regions in China is relatively high, with Jiangsu and Zhejiang being the main production areas. In the past two years, affected by the COVID-19, the operating rate of foreign chemical fiber enterprises has declined, and the international market demand has shifted to the domestic market. Against this background, the proportion of China's chemical fiber exports has increased. In 2020, China's chemical fiber exports will be about 4902200 tons.

Worldwide, regions such as Europe, North America, and Japan have a relatively high level of development in the chemical fiber industry. These regions place greater emphasis on the high-end, refined, differentiated, and innovative development of chemical fiber products. Compared to European and American countries, China's chemical fiber industry started later, and there is still a certain gap in product quality, technological level, equipment level, etc. There is still significant room for improvement in the industry in the future.

There are many types of chemical fibers with a wide range of applications. In recent years, with the increase in market demand and the improvement of production technology, the production scale of chemical fibers in China has continued to expand. At present, China has become a major producer of chemical fibers in the world. Due to the late start of the industry, there is still a certain gap in the development level of China's chemical fiber industry compared to European and American countries. In the future, the industry needs to further develop towards high-end, diversified, and refined directions.
