High-end, green, intelligent, see how the chemical fiber industry to win the future with strength

Coal to ethylene glycol technology uses relatively rich coal resources in China instead of oil route to produce ethylene glycol, which relies heavily on imports in China, and has an important impact on the development of China's energy industry, modern coal chemical technology and polyester industry. Yao Yuangen, a researcher at the Fujian Institute of Material Structure of the Chinese Academy of Sciences, discussed the development direction of coal-to-ethylene glycol technology and industry around the current application of coal-to-ethylene glycol products in related polyester enterprises and the influencing factors on the quality of downstream polyester products.

Ye Guangdou, professor of Sichuan University, introduced the development status of continuous basalt fiber in China. He suggested that the industry should strengthen basic technology research, break through the key core technology of continuous basalt fiber raw materials and the pool kiln method, large leakage plate, intelligent fiber production technology, strengthen fiber performance and application research, carry out the research of basalt melt preparation iteration technology, rationally layout bigger and stronger the whole industrial chain, and promote the continuous basalt fiber industry to achieve high-quality development.

Carbon neutrality puts forward new requirements for the development of the industry. The lightweight characteristics of carbon fiber and its composite materials play an important role in promoting energy conservation and consumption reduction, while carbon neutrality requires green energy such as wind power, photovoltaic and other industries have a large demand for carbon fiber, but the production of carbon fiber itself needs to consume a lot of electricity. With the improvement of wind power technology, its cost is getting lower and lower. Can wind power be used to reduce the cost of carbon fiber? Yan Bing, industry mentor of the Material Department of Suzhou University, proposed in his speech a new energy ecosystem, in this system, carbon fiber can be used as wind power blades, wind power hydrogen production, promote hydrogen energy vehicles forward, while the demand for refueling stations increases, it is necessary to build more distributed fan power stations for hydrogen production. Hydrogen cars need carbon fiber, wind power needs carbon fiber. This mutual promotion can promote the growth of volume and the reduction of cost, which is a perfect industrial chain for the carbon fiber industry.

Explore the practical path to achieve the goal of "double carbon"

During the "14th Five-Year Plan" period, under the guidance of green development and double carbon goals, the chemical fiber industry not only shares the social responsibility of green manufacturing and ecological protection with the whole textile industry chain, but also independently undertakes the important mission of developing diversified biological raw material resources, improving the recycling level of fiber products, and reducing carbon emissions of industry enterprises.

At the forum on the green development of chemical fiber industry, Wang Huaping, a researcher and doctoral supervisor of Donghua University's School of Materials, introduced the technical route and industrial development direction of bio-based chemical fibers. He introduced that as of 2019, the total production capacity of bio-based chemical fibers has reached 5 million tons/year, and bio-based synthetic fibers, new bio-based cellulose fibers, and Marine bio-based fibers have achieved large-scale production, and the application technology is mature, and the application field is constantly expanding. The development trend of bio-based fibers in the future will revolve around integration and development, including integration and innovation of technology, integration and development of bio-based fibers and green fibers, integration and development of green manufacturing, integration and development of industrial chain innovation and chain, integration and development of terminal brands, integration and development of recycling and regeneration, integration and development of the whole life cycle, and sustainable integration and development.

Plastic particles are an unavoidable problem for the sustainable development of the chemical fiber industry, and clothing washing and wearing are an important source of fiber microplastics in the environment. This fiber microplastics is non-degradable, causing great pressure on the ecological environment and serious harm to human health. Li Guang, a professor in the School of Materials Science and Engineering at Donghua University, introduced several current strategies to inhibit or intercept the release of fiber microplastics from clothing. She pointed out that the discharge of laundry wastewater is the main way for fiber microplastics to enter the environment, in order to inhibit the production of fiber microplastics during the washing process, filters can be added to the water outlet of the washing machine and laundry bags can be used. The surface of nylon fabric is coated, and the surface functionalization of nylon fabric can be treated with modified pectin.
