Important Breakthroughs Have Been Made In The Field Of High Performance Fiber Materials.

At present, high performance fibers such as carbon fiber T300, aramid, polysulfonamide, ultra high molecular weight polyethylene, polyphenylene sulfide and basalt have achieved breakthroughs in industrialization, and the level of functionalization and differentiation of chemical fiber products has improved significantly.

The key technologies such as fine denier and microfiber, profiled fiber, high moisture conductive polyester fiber and super Imitation cotton polyester fiber have been broken through and achieved industrialization.

The bio based fiber produced from renewable, biodegradable bamboo pulp and hemp stalk pulp has been commercialised, and solvent based cellulose fiber has broken through the key technology of 1000 ton level quasi industrialization.

The key technology of refinement of jute fiber has been breakthroughs and the industrialization application of refined jute has been achieved. In view of the need of genetic improvement of silk quality and processing characteristics, the genome map of silkworm has been completed, and the key technology of natural colored silk has been broken through. A breakthrough has been made in the research of high yield and high quality pgenic cotton flowers, which can greatly increase cotton production and significantly improve the fineness of cotton fiber.

The industry is currently short of research and development on materials such as carbon fiber, aramid fiber and ultra-high molecular weight polyethylene fiber. The key technologies and equipment have not yet been broken through, and it is difficult to reach the industrial scale. The import dependence of aramid fiber is over 95%, and the dependence degree of carbon fiber imports is more than 80%; the new functional fibers with high added value have yet to be expanded and upgraded, and the proportion of functional and differential fibers is still low; the dependence of the chemical fiber industry on fossil resources has exceeded the warning line, while the research on new type biological fibers based on petroleum is basically in the tracking stage.

In view of the problems in the development of science and technology in China's textile industry and following the development trend of international textile technology, the development trend of fiber materials in China will continue to be high performance, fiber varieties to differentiate, fiber processing to ecological, and fiber scale to nano scale.

In the field of high performance fiber, we should pay more attention to the systematic research on the formation mechanism, evolution law and control methods of multi-scale structure in the process of fiber production, the key technologies and equipment for continuous and stable preparation of high performance fiber polymer, the key technology and equipment of liquid crystal spinning, the key technology and equipment of gel spinning, the key technology and equipment of high viscosity spinning fluid defoaming, and the research and development of low cost carbon fiber preparation technology.

In the field of differentiation and functional fiber, we should focus on the research and development of polyester fiber high simulation technology, polyamide fiber high quality chip raw material technology and supporting technology, and promote the application and development of fiber and textiles, and expand the downstream application areas, and find new growth points.

We should focus on developing the composite technology of functional membranes and textile fabrics in functional materials of electrospun nanofibers, the research and development of biomedical materials for electrospinning nanofiber membranes, and the realization of diversified applications of electrospinning nanofibers macro quantization manufacturing.

In the field of new bio based fibers, we should pay attention to the development of bio based fibers and biochemical raw materials, and make full use of resources such as agricultural products, crop waste and bamboo and fast-growing forests to achieve the industrialization of renewable, degradable, recyclable, environmentally friendly bio based fibers and comprehensive development and utilization.
