Bio-based fibers become a new strategic material for the textile industry

Recently, the National Development and Reform Commission, the Ministry of Finance, the Ministry of Industry and Information Technology, the Ministry of Science and Technology, the Chinese Academy of Sciences and other departments are jointly promoting the "bio-based material major project implementation plan" and "bio-based chemical fiber and raw material implementation plan."

The reporter learned that in accordance with the "Twelfth Five-Year Plan for National Economic and Social Development" and the "Twelfth Five-Year Plan" for the development of bio-industries, implementation of major projects for the implementation of bio-based materials projects will break through to restrict the development of bio-based materials industry. The bottleneck of key technologies, accelerate the industrialization process, build a bio-based material technology and product research and development platform and standard system to achieve large-scale production of bio-based chemical fiber and application areas, and effectively enhance the international competitiveness of China's bio-based materials industry.

Duan Xiaoping, president of the China Chemical Fiber Industry Association, said that bio-based chemical fiber and its raw materials are important components of China's strategic emerging bio-manufacturing industry, with green, environmentally friendly, renewable raw materials, and biodegradable and other excellent features. Solve the current global economic and social development is facing a serious shortage of resources and energy, as well as environmental pollution and other issues. The vigorous development of bio-based chemical fibers and their raw materials is a requirement for the sustainable development of the chemical fiber industry and the realization of a low-carbon economy. It is necessary to cultivate and develop strategic emerging industries, realize strategies for strengthening the country's textile and fiber industries, and improve the people’s healthy living standards, and for alternative fossil resources, It is of great significance to develop a recycling economy and build a resource-saving and environment-friendly society.

At present, the major projects of bio-based chemical fiber and its raw materials are the breakthroughs for the industry, with “three alternatives” (material substitution, process substitution, product substitution) and “three combinations” (combined with the bio-chemical industry and energy conservation and environmental protection , combination of waste utilization, integration with function improvement and promotion and application) and “three priorities” (focusing on the production and application of biological diols, focusing on the preparation of polylactic acid fiber raw materials and fiber application technologies, and focusing on capturing marine bio-based Diversified fiber materials and large-scale production technologies As the current important task for the development of bio-based chemical fibers, the development of non-food bio-based raw materials and new-type bio-based chemical fibers that replace petroleum resources; breakthroughs in green processing and new processes of bio-based fibers, and equipment integration Technology, to achieve industrial production; to open up bio-based chemical fiber applications, promote industrial chain leapfrogging and sustainable development, and achieve significant economic and social benefits.

Shusheng Silk is a representative of bio-based PTT fibers and is a product developed by Fujian Haixing Material Science and Technology Co., Ltd. and DuPont. Zhang Lianjing, general manager of Haixing, said: “35% of the raw materials of Shulan Silk use non-oil renewable biomass resources, reducing the reliance on petroleum and petrochemical products. Compared to the production of nylon 6 fibers by the petrochemical process, the same amount of Elasticity can reduce energy consumption by 30% and CO2 emissions by 63%. It is a recyclable, recyclable green fiber."

Wang Yuping, secretary-general of the China Chemical Fiber Industry Association, said that vigorously developing bio-based fibers will bring about profound changes in the related technologies, processes, equipment, talents and business models of the textile and chemical fiber industry. The bio-based fiber industry will give the textile industry flourishing prospects and potential for inexhaustible room for improvement.

China's bio-based chemical fiber is about to enter a period of rapid growth under the new circumstances of national policy encouragement, special support, business investment, and association promotion. According to the "30-year road map for China's biomass fiber and bio-chemical raw materials technology and industry development" published by the China Chemical Fiber Industry Association, it can be seen that by 2015, the output of China's bio-based fibers and biochemical raw materials is expected to reach 5.1 million tons. Increased by 17%. Among them, PTT fiber will reach 150,000 tons, alginate fiber will reach 10,000 tons, and PLA fiber will reach 50,000 tons. The industrial chain extends upstream and downstream to achieve raw material substitution, process substitution, product substitution, and broadening the downstream application fields, so as to achieve a sound economic and social development.
