Recently, the World Fiber New Materials Conference and the 23rd China International Chemical Fiber Conference was held in Hangzhou, the experts said that the current chemical fiber industry has entered the adjustment period, the traditional synthetic fiber production capacity is serious, the development of new chemical fiber materials are gradually becoming the industry's main theme In the future, the development of industry depends on the further breakthrough and innovation of major technology.
Traditional chemical fiber production overcapacity
China Textile Industry Association, vice president of China Chemical Fiber Industry Association, said Deng Xiaoping, 2016, China's chemical fiber production of 49.43 million tons, accounting for 74% of the world's total chemical fiber, chemical fiber accounted for China's total textile fiber processing 83 %. However, the industry in recent years is also facing clumsy overcapacity problem.
Donghua University Professor Zhu Meifang said that chemical fiber materials is not only clothing, home textile fabric raw materials, but also an important basic engineering materials by the production technology and market capacity and other factors, China's chemical fiber industry overcapacity phenomenon is very obvious, has now entered The adjustment period.
Nippon Chemical Fiber Association, vice president and chairman of the field, said the future, the global production capacity of synthetic fiber is expected to grow 2.6% per year in 2020 will reach 93.3 million tons of synthetic fiber consumption is expected to grow 3.6% per year, Reaching 70.8 million tonnes, and the gap between global production capacity and consumption will reach 22.5 million tonnes, and the excess capacity will be reduced from 27.3% in 2015 to 24% in 2020. 'While this figure is getting smaller but overcapacity The problem still exists, must be the attention of the whole industry. "Ueda Akira said.
New prospects for new chemical fiber materials
With the highlight of the problem of overcapacity, as well as the supply side of the structural reform continued to advance, chemical fiber materials are gradually from the traditional conventional synthetic fiber to the high-end, functional, intelligent chemical fiber new materials.
China Textile Industry Federation Party Secretary and Secretary General Gao Yong said that the next 20 years, the world's carbon fiber, aramid, etc. as the representative of the advanced fiber materials will usher in an important strategic stage of development, each year will be more than 15% This stage will also become China's traditional chemical fiber enterprises into the field of high-tech materials a major opportunity.
At present, China has become the country with the highest coverage of high-tech fiber (including bio-based chemical fiber). The high-performance fiber production and the potential consumption are the first in the world. The development of new chemical fiber is becoming the main theme of the industry.
In addition, in the Ministry of Industry and Information Technology and the National Development and Reform Commission issued by the end of 2016, "Chemical Fiber Industry 'thirteen five' development guidance ', but also the status of China's fiber materials industry has been positioned, that is, the importance of strategic emerging industries The chemical fiber industry is no longer only used in traditional textile and clothing, but related to national defense, military, transportation, energy, health and other aspects of traditional chemical fiber materials can not meet the needs of these areas, fiber materials from Passive adaptation to the initiative to innovation and development. 'Zhu Meifang said.
Improve the level by new technology
Duan Xiaoping believes that the level of development of a country's fiber materials usually focus on four aspects: First, the bulk of the basic raw materials, that is, the level of development of functional textile new materials; Second, bio-based chemical fiber and core technology development; Is a breakthrough in the industrialization of high-performance fiber technology; four fiber materials, cutting-edge technology research, etc. These are closely related with the new chemical fiber materials.
'In the new chemical fiber materials, we are not in place in the current research and development, such as the lack of or no high level of R & D institutions, market applications and development can not keep up, in large aircraft and aerospace fiber materials and other aspects of technology Barriers, etc. Not only that, there are foreign affiliates or official agencies, for each material, each component has a strict certification requirements.China in recent years to develop carbon fiber and other chemical fiber new materials through its certification is very difficult, This is also the development of our problems encountered. 'Duan Xiaoping said.
Duan Xiaoping said that the development and quality of functional fiber materials, the industrialization of bio-based chemical fibers, the industrialization of high-performance fibers and the serialization of products are the urgent problems to be solved in the current industry, which depends on further technological innovation. Functional fiber materials development and quality improvement, to develop large-capacity polymerization of spinning equipment, breaking the nylon ring hair technology to enhance the level of large-capacity nylon equipment to further reduce the production cost of conventional fibers; the development of new fiber varieties, the development of a new generation of copolymerization, Blending, multi-component, multi-component online addition technology to achieve deep dyeing, ultra-fine denier, anti-pilling, anti-static and other differentiated fiber scale production; development of flexible manufacturing technology, construction of high efficiency flexible manufacturing technology innovation platform, System to solve the technical bottleneck of industrial development.
In the bio-based chemical fiber industry, the bio-based chemical fiber to break through the manufacture of key equipment to overcome the biological-based chemical fiber and raw materials industry bottlenecks; bio-based synthetic fiber to break through the bio-based synthetic fiber raw materials, industrial production technology, Development of non-food bio-based fiber raw materials production, to enhance the polylactic acid, polytrimethylene terephthalate and bio-based polyamide polymerization, spinning and dyeing and finishing industrialization technology level.
In the high-performance fiber industrialization and serialization, need to further enhance and break the key production and application of key varieties of high-performance fiber technology to further improve the stability of fiber performance indicators; to form carbon fiber, aramid, polyimide fiber and poly Tetrafluoroethylene fiber and other high-performance fiber varieties of serialization to meet the needs of downstream users; breakthrough high-strength high-model carbon fiber, continuous silicon carbide fiber, silicon boron nitride fiber, poly aryl ether ketone fiber and other new high-performance fiber preparation and industrialization The key technology.
