High Performance Fiber Brings Vitality To The World'S Chemical Fiber Industry.

"Receiving the world" financial crisis The impact of global chemical fiber production has been the first negative growth since 1982, but we should see that the continuous innovation of high performance fibers in the world has brought vitality to the development of chemical fiber industry. This is the voice delivered at the fifteenth China International Chemical fiber conference innovation and upgrading sub forum. The forum has not only greatly encouraged the confidence of the world's chemical fiber entrepreneurs, but also pointed out the direction for the healthy development of the world's chemical fiber industry.

Vigorous development of high-performance fibers

In all walks of life generally affected by the financial crisis, the world's major high-performance fiber producers rely on technological innovation to increase production efficiency, reduce costs and develop new varieties, and the growth rate of demand basically stays at two digits. At the forum, Luo Yifeng, director of the national special synthetic fiber information center, introduced the progress of the world's high-performance fibers.

The impact of the financial crisis on Para aramid and its copolymers is relatively small. The continuation of the world war on terror, the intensification of labor protection, the lightening of spanport vehicles, energy saving and environmental protection further promoted its development. According to the introduction, DuPont invested $500 million in 2010 to expand the production capacity of para aramid amide by 25% and increase the new product of "Kevlar ED" with high curling processing. The Japanese company plans to invest 6 billion yen in 2009 to expand the production capacity of Technora fiber by 50%, to reach the scale of 3000t/a, and to increase the capacity of "Twaron" by 15%, so that the production capacity can be increased to 27500~28000t/a. In South Korea, KOLON and Xiao Xing have successively realized the industrialization of para aramid fibers, with capacity of 1000~2000t/a and 1000t/a respectively. enterprise The production of para aramid fiber plant is being developed and constructed. It is expected that the total capacity of 5000t/a will be formed by 2010.

With the continuous improvement of foreign technology and the continuous development of new markets, Xuan Wuyan (BS) fiber is expected to become the fourth largest high-strength and high modulus fiber. There are 4 BS fiber manufacturers in Ukraine, one of which is a joint venture with TOYOTA automobile in Japan in 2000, specializing in the production of automobile mufflers. Now the capacity is 1200t/a. Another company invented a new series of BS devices in 2006, which can reduce the production cost and make it less than E- glass fiber, thus opening up a broad market space, and now its capacity is close to 1000t/a. After many years of research and development in China, at least 6 companies have been put into production: Chengdu Tuo Xin Basalt Fiber Industry Co., Ltd. has developed a low energy consumption device to produce continuous roving and fabric, with capacity of about 300t/a; Mudanjiang electric power group basalt Co., Ltd. has formed 800t/a capacity; Zhejiang stone gold Basalt Fiber Co., Ltd. is building 1000t/a production line, and the total capacity of the country is estimated to be about 2600t/a; Beijing Anshan Fiber Co., Ltd. is planning large-scale andesite fiber factory.

Developing new and high technology Fiber Dimension is the key.

Under the guidance of the government's macroeconomic regulation and control and industrial policy guidance, the chemical fiber and related enterprises have developed rapidly through the combination of production, teaching, research and administration, collaborative research, independent research and innovation, and high technology, differential and functional fibers. Ye Yongmao, vice president of China Chemical Fiber Industry Association, pointed out that at present, high temperature resistant Aramid 1313, super high strength polyethylene, polyphenylene sulfide (PPS), polysulfonamide fiber, basalt fiber and so on have been in the stage of industrialization to industrialization, including carbon fiber integrated technology of raw silk, carbonization and composite materials, aramid 1414, aramid III, lyocell and other fibers are in the pilot stage of industrialization, and PBO, SIC, PBI and other fibers need further pilot test or industrialization.

We should strengthen the support for heavy point projects, strengthen the support for heavy point projects, identify weaknesses in international development, organize multi-party forces, and build a platform for innovation services in industry, academia and research. We should fully understand the risk factors of high-tech fiber industry, strengthen the technical and economic feasibility analysis, actively and steadily promote the implementation of the projects, further strengthen the engineering and supporting research on technology and equipment, strengthen the research and development efforts of special fiber materials and equipment for high temperature and corrosion resistance, further strengthen the informatization and standardization of hi-tech fiber industry, strengthen all kinds of technical regulations, standards, testing and certification systems in line with the international practice, safeguard industrial safety and sustainable development, continuously improve the capability of independent innovation, pay attention to protection and intellectual property rights, and enhance the ability to safeguard their rights. In view of the gap between China's high performance fibers and international advanced level, Ye Yongmao put forward the key task of innovation and development of the chemical fiber industry in the new era: we should fully recognize the high-tech fiber and developed countries in China.

"Although the financial crisis has brought enormous difficulties to the chemical fiber industry, it has also spawned new and high technologies to promote the industry's survival of the fittest, structural optimization, energy conservation and emission reduction, and industrial upgrading." Ye Yongmao is full of hope for the future.

Carefully mounted carbon fiber

Carbon fiber is one of the topics that the attendees pay close attention to. In the past 3 years, China has made breakthroughs in the research and development of carbon fiber. This is mainly reflected in the bottleneck restricting carbon fiber - breakthroughs in precursor technology. The carbon fiber produced by our own raw silk has basically reached the T300 level of Dongli, Japan, and initially met the needs of domestic military and civilian products. At the same time, it also broke through the pilot level of laboratory and production line, and has built several thousand ton production lines in China, and several thousand ton class production lines are under construction. Among them, Weihai expanded Fiber Co., Ltd. used the carbon fiber produced by self developed raw silk, after comprehensive and strict comprehensive evaluation, confirmed that it has reached the level of T300 fiber in Japan. The expanded kiloton production line was put into operation in 2008, and its carbonization equipment was introduced by Harper company, and its second sets of 1000 ton production line equipment have also been spanported. It is being installed and debugged, and the capacity of 3000 t/a will be built in the near future. Jiangsu Lianyungang Zhongfu Eagle Carbon Fiber Co., Ltd. has accelerated the construction of a 1000 ton production line, from the original silk to carbon fiber has complete independent intellectual property rights, equipment design and manufacture, and has started production trial operation in December 2008, long-term plan to 10000 tons of production line.

Chen Shaojie, a researcher at Shenyang Institute of aircraft design, said that the global financial crisis of carbon fiber has ended. In 2009, the world's carbon fiber can achieve a new balance between supply and demand. In 2010, there will be more production than sales and oversupply. On the development of carbon fiber, Chen Shaojie put forward five suggestions: prudent carbon fiber, such as no reliable technical source, independent intellectual property rights without raw silk and carbon fiber, and no strong investment capability, so that carbon fiber products need to undergo strict technical evaluation; attention should be paid to the development of downstream products; the application in the industrial field is the direction of product development; attention should be paid to design and manufacturing technology.
