National Policy Is Closely Related To The Industrialization Of Hi-Tech Fibers.

The rapid rise of modern technology and related industries has promoted the rapid development of high-tech fiber and composite materials.

Synthetic new materials have entered into the life sciences, aerospace, electronics, medical and health industries, and become the new growth point of the development of chemical fiber technology.

At present, Japan, the United States and other developed countries still occupy the high-end technology and market of high-tech fibers in the world. Japan has the strongest R & D power in high-tech fibers such as carbon fiber, aramid fiber and polyphenylene sulfide. In the industrialization of biotechnology, the United States occupies a leading position, especially in PLA technology and propylene glycol (PDO) industrial production technology.

The development of high technology fiber materials, renewable bioengineering technology and various high-performance differential functional fiber technology has become the focus of the development of chemical fiber technology in China and even in the world in the new era.

In the field of high tech fiber, developing countries have launched a battle with developed countries.

High tech fiber production capacity will double in 5 years.

Over the past five years, China's chemical fiber industry has experienced a period of rapid development, but mainly in the conventional way.

To this end, during the "12th Five-Year" period, China's chemical fiber industry should strengthen product development, expand downstream application areas, seek new growth points, create demand and lead the market.

At the same time, the differential rate of chemical fiber has been greatly increased. In 2015, it strives to reach 60%, of which polyester filament reaches 70%.

We will continue to promote the industrialization of biomass fiber and hi-tech fiber. By 2015, the capacity of biomass regenerated fiber will grow from 1 million 800 thousand tons to 3 million 520 thousand tons. The biomass synthetic fiber will grow from 35 thousand tons to 210 thousand tons. The production capacity of high-tech fiber will be doubled, from 70 thousand tons to 140 thousand tons (including bamboo fiber), including 6000 tons of carbon fiber, 14000 tons of aramid fiber and 7000 tons of polyphenylene sulfide. Other new types of polyester and special fibers such as PI and PBO have made breakthroughs to achieve industrialization level.

What needs to be more clear is that during the "12th Five-Year" period, we should focus on breaking through the current constraints on the development of the industry.

National policy is closely related to the industrialization of hi-tech fibers.

The international financial crisis, which broke out in the second half of 2008, has brought about profound changes in the global economic development mode. The development of strategic emerging industries has become the commanding height of the new round of economic and technological development.

This year, we can see from the guidance catalogue of the 2011 New Textile Industry issued by the national development and Reform Commission that polylactic acid fiber, seaweed fiber, chitin fiber, polyhydroxyacrylate fiber, animal and vegetable protein fiber and other biomass fiber will usher in a great opportunity for development.

In addition, the development and production of organic and inorganic high-performance fibers and products, such as carbon fiber, aramid fiber, polysulfonamide fiber, Gao Qianggao mould polyethylene (ultra high molecular weight polyethylene) fiber, polyphenylene sulfide fiber, polyimide fiber, polytetrafluoroethylene fiber, basalt fiber, silicon carbide fiber and high strength glass fiber, have all been included in the encouragement category, which is highly valued by the state.

In order to break through the bottleneck of high-tech fiber industrialization, high-tech fibers should be organized as "national team" in the future with the goal of "industrialization, production, research and industry chain".

According to the guidance catalogue of the 2011 New Edition, the industrialization of the domestic blank varieties of high and new technology fiber, the upgrading of the quality performance of the existing high-tech fiber varieties, the industrialization of downstream composite materials and the development of industrial textiles are all included in the category of key encouragement.

In July 7th, the Ministry of industry and information technology released the guide to the development of key technologies for common industry (2011), which involved 8 key generic technologies in the textile industry. These technologies have great and far-reaching significance for the textile industry to achieve the goal of sustainable development and to build a textile power.

Carbon fiber, para aramid fiber, high strength and high modulus polyethylene fiber and so on are the new high-tech fiber technologies highlighted in this published guide to the development of key common technologies of industry (2011).

After several years' efforts, China's carbon fiber industry is forming an industrial scale. The technology of carbon fiber precursor, pre oxidized wire and carbonization has matured, and the key equipment such as pre oxidation furnace and large carbonization furnace has been able to produce independently.

Kiloton carbon fiber equipment and carbon fiber tow (1 ~ 6K) have been mass produced, and the technology of high strength and high modulus series such as carbon fiber T700 and T800 has been expanded.

The technology of aramid fiber 1000 ton scale industrialization is being perfected. The aramid fiber has been industrialized and its total output has exceeded 10000 tons.

The industrialization of high strength and high modulus polyethylene fibers has been realized.

Expanding the application of high-tech fibers in the industrial field

Through technological innovation such as "original innovation", "integrated innovation", "digestion and absorption and re innovation", we should speed up the application of high and new technology in the industry, strengthen and increase the contribution rate of science and technology and the contribution rate of brand, speed up the optimization and adjustment of product structure, vigorously develop functional and differential fibers, and comprehensively enhance the application ratio of chemical fiber in the industrial field.

We should vigorously develop new technologies, new technologies, new materials and new equipment for energy conservation, emission reduction, low consumption and low carbon, promote cleaner production and develop cleaner products, implement circular economy, research and develop degradable, renewable, recyclable materials in traditional fields and new fields; especially focus on the development and application of practical technologies and products with high efficiency, high added value, high performance, high yield, low consumption, low cost, low price and low environmental risk (4H4L).

First of all, speed up the application of high technology in chemical fiber industry.

Adopting advanced and applicable technology and high and new technology, especially using modern material science, information technology, nano technology and biochemical technology to pform and upgrade the traditional chemical fiber technology, equipment and production automation control level, we will solve many problems in the whole production process of chemical fiber products.

We should overcome technical difficulties such as plasma etching, nuclear magnetic resonance and biochemical modification, accelerate the industrialization of new polyester and its industrial chain, and strive to have large-scale production lines of industrialization and localization in all varieties.

Secondly, we should vigorously develop multi-functional and differentiated fibers, promote downstream application development, and increase the added value of all links.

At the same time, we should promote the development of product research and development and textile products, and increase the chemical fiber differential rate to 60% by 2015.

Finally, we should vigorously develop industrial fiber and increase the proportion of application.

We should focus on the research, development and industrialization of high-performance multi-functional, composite differential and functional fiber materials. We will focus on developing new technologies and varieties of new fibers, such as polyester and fiber, differential, functional acrylic, functional nylon and so on, strengthen the industrialization research and development, develop high-performance fabrics, increase the added value of products, attach importance to the matching technology development of differential and functional fibers, and further expand their applications in the three fields of civilian high simulation, super simulation clothing, home textiles, industry, and non fiber, synthetic new materials and high technology fields.

Forming an integrated innovation system of upstream and downstream integration

The development and production of hi-tech fiber is highly interdisciplinary and highly integrated with many engineering technologies, and there is no foreign technology that can be used for reference. Our country must further strengthen its independent innovation, speed up the R & D, industrialization and industrialization of basic technology and equipment, and have enough basic scientific research and Application technology support, advanced industrial technology guarantee, strict process and quality management guarantee, at the same time, we should strengthen the research and development system of production, learning and research, further promote the coordinated development of industrial chain, supply chain and knowledge chain, and promote the integrated development of upstream and downstream.

At the same time, we should continue to promote the industrialization and application of hi-tech fibers, and accelerate the industrialization of high performance fiber and composite materials such as high performance carbon fiber, aramid fiber, polyphenylene sulfide, ultra-high molecular weight polyethylene, basalt fiber, polyimide and new polyester, so as to increase the total output.

According to authoritative departments, in the next 5 years, China should basically build up the world's chemical fiber production and R & D base, break the bottleneck of hi-tech fiber, and achieve comprehensive industrialization results in key varieties such as carbon fiber, aramid, polyphenylene sulfide, ultra-high molecular weight polyethylene and basalt fiber, and create high-tech production, learning, research and production and development and marketing system with Chinese characteristics, laying a solid technical foundation for overtaking the developed countries in an all-round way.

We will actively promote the industrialization and application of new types of polyester (PTT, PEN, etc.) and the development of new technologies, including the polymerization of polythalene (PTT) resins, the development of key technologies and equipment and products of PTT fiber industrialization, the polymerization and spinning technology of polysebacate (PEN), the research of new technology for the synthesis and preparation of cationic copolyesters, the digitalization of the direct spinning process of high-quality polyester filament, and the research and development of the new generation of key technologies and equipment for non fiber polyester.

Reporters learned in the interview that high-tech fibers and functional fibers are the crystallization of high technology in many fields and disciplines. However, China started late in this field, and there is a fault between basic research and industrialization.

In addition, backward manufacturing equipment and inadequate research and development.

High tech fiber materials are not only complicated in production technology, but also demanding in production conditions. But at present, domestic production equipment, materials, meters, automatic control systems and so on can not meet the requirements.

Experts pointed out that the ultimate solution to these bottlenecks is to rely on market-oriented and integrated system innovation.

Compared with the enterprises in developed countries, the vast majority of chemical fiber enterprises in China are far from enough to participate in market competition.

This requires domestic enterprises to rely on new and high technologies to enhance the development capabilities of new materials and new products, and to form core technologies with independent intellectual property rights. On the other hand, we must constantly improve our ability to respond to domestic and foreign markets and enhance the ability of enterprises to resist risks.

At present, domestic enterprises need to start from the digestion, absorption and re innovation of relevant foreign fiber and material technology, and on the basis of maintaining the international advantages of conventional chemical fiber materials, step by step to promote integrated innovation with related fields of new fiber, and gradually cultivate the ability and market demand of industrialization.
