At present, the biological base covers almost all varieties, chemical fiber production, is a new fiber does not lag behind the foreign varieties, and in the pursuit of environmental protection in trend of the sustainable development of modern industry, has a large space for development and broad prospects for development.
As one of China's seven major strategic emerging industries is an important part in the field of new materials, biological base of chemical fiber in our country through the "11th five-year plan" period of rapid development, has made some achievements, cellulose fiber has been realized industrialization, scale, technology level, ranks the world's leading engineering; And poly (lactic acid) (PLA) fiber is realized industrialization; 1, 3 - propanediol and 1, 4 - butanediol, biological method of glycol monomer, polymer and fiber processing progress rapidly; New type regenerated cellulose materials such as bamboo pulp, hemp pulp diversification, thousand tons Lyocell fiber etc has made significant breakthroughs of the whale set industrialization techniques, laid the groundwork for each Lyocell fiber industrialization development in China. However, due to the industry started relatively late, weak basic research and innovation ability insufficiency, the downstream application in narrow, the biological base of chemical fiber industry in China size is small, the production cost is high, the production raw materials a head out, low engineering level must solve and breakthrough.
At present, the national development and reform commission, ministry of finance, the ministry, ministry of science and technology, Chinese academy of sciences and other departments are combination of major project implementation plan "" national biological base material -" special plan "biological base of chemical fiber and its raw materials. Understanding the industry development significance, discusses developing mode, increase capital investment, especially for countries to seize the "twelfth five-year" period of new and high technology material included in the opportunity to accelerate the development of seven strategic emerging industries, is more important and urgent.
Deep understanding of development
In recent years, with the global shortage of oil resources and the increasing deterioration of the ecological environment, the traditional petroleum chemical technology and products and the side effects of unsustainability is increasingly significant. Ministry of industry and consumer goods industry department deputy director wang wei said, biological base of chemical fiber and its raw material is comply with the development of the need of the situation. Chemical products produced by biomass feedstocks to replace petroleum products has become the inevitable trend of current development.
At present, more than 90% of the products based on petroleum chemical fiber industry in China, raw material costs accounted for more than 80% of the cost of production, and imports account for about two-thirds of the total demand for chemical fiber raw materials, in fact external dependency has gone beyond the steady development of the industry security cordon, on the healthy development of the whole industry chain with investment risk and instability. As the world's largest producer of chemical fiber, chemical fiber in China's development will be restricted by more and more. Deng xiaoping said that China's chemical fiber industry association end, actively developing biological base of chemical fiber and its raw materials industry, not only is an important way to realize the sustainable development of chemical fiber industry, but also carries the responsibility with chemical fiber power.
Abundant biomass resources is green chemical raw materials of the future, more and more chemical products can be obtained by biomass resources. At present, the world chemical industry giants such as dupont chemical, DOW chemical, DSM, basf and other companies have been from the beginning of the last century from the traditional chemical fiber and chemical industry to biological research and industrialization base of chemical fiber and raw material, has been as the most priority to the development of business. Has a deep research on biological base of chemical fiber in China's chemical fiber industry association, honorary President of Zheng Zhi art said, from biological chemical fiber base way to obtain raw materials trend has become increasingly apparent in the whole world, the countries of the world, especially developed countries after the world financial crisis, the development of biological industry as out of the woods, for the high-tech commanding heights, the prosperity of national strategy.
It is understood that the "twelfth five-year" national strategic emerging industry development planning "and" chemical fiber industry "twelfth five-year" development plan "is the development of biological base of chemical fiber and its raw materials as a important special content. Deng xiaoping pointed out, from the maintenance national security in our country, cultivating the height of the strategic emerging industries, earnestly implement the plans for the development of the biological base of chemical fiber and its raw materials.
Positive innovation and development mode
About planning shows that by 2015, the biological base of chemical fiber and its raw material production in China will by 2012, 2012 tons (including traditional bio-based renewable fiber) increased to 5.1 million tons, the annual average growth rate of 17%. Biological base of chemical fiber and its raw material output will reach 105 billion yuan, the added value of 44 billion yuan.
Industry experts pointed out that accelerate the development of industry, should give full play to the market to the basic role of optimizing the allocation of resources, make the enterprise really become the main body of technological innovation and industrialization development, also want to give full play to the government's role of strategic emerging industries, in terms of policies and regulations, systems and mechanisms conducive to a sound environment for industry development, handle properly the relationship between industrial development and corporate competition, established for biological technology innovation and industrialization good support platform. Shanghai cathay biotechnology industry co., LTD., chairman of LiuXiuCai said enterprises in the main body position in the market, enterprises on the market front, can choose potential products, countries should do a good job of intellectual property protection. In pure chitosan fibers and industrialization projects with independent intellectual property rights of hayes Moore biological technology co., LTD. And, at present has been declared national patents and international more than 120. Vice manager Zhang Mingyong emphasized the industry the importance of the protection of intellectual property rights. Through patent protection for intellectual property rights, he said. Domestic enterprises should have the consciousness of patent applications.
On the development steps, industry development is focus on the urgent demand of national economic and social development, a batch of good basic conditions, technical conditions are ripe, growth potential, high correlation of modern biological industry focus areas and major products. Biological base of chemical fiber and its raw materials professional committee secretary general Li Zengjun said, industry development will focus on breakthrough plays an important support and a group of leading role at the forefront of biological technology, the formation of independent intellectual property rights, conquers the highest position in international competition, and accelerate industrialization.
On the biological base of chemical fiber industry development model, can be summarized conventional fiber development experience. Deng xiaoping said, this can avoid detours. Equipment research institute of peoples' han ma research center chief engineer says, through the development of the industry, can no longer walk the development of the conventional fiber. In training talents, the protection of intellectual property rights, mining industry culture, pay attention to environmental protection technology to a breakthrough and innovation. Guangdong baihe medical representatives agreed that industry can no longer like the traditional fiber, rushing to enter. Non-benign competition will produce adverse effect to the development of the industry.
To improve industrial technology
Biological base of chemical fiber and its raw material is strategic new industries, and countries technology blockade is common, international cooperation in space is not big, industry is generally believed that we should set the idea of relying on independent development strategic thinking.
Develops the biological base of chemical fiber raw material resources and the development of new production technology into the industry's focus of attention in current technology. Donghua university vice-chancellor Zhu Meifang said, in terms of technology, we now basically has the following points: one is using ionic liquids, non-toxic safety, such as low temperature alkaline/urea solution can be recycled solvent, melt spinning, etc. New technology of preparation of cellulose fibre; Second, using chitin, seaweed and other biomass and various protein as raw material to produce biological base of chemical fiber; Three is the research and utilization of agricultural products, such as crop waste resources, the biosynthesis technology preparation of poly lactic acid (PLA), poly (butyl diacid butyl glycol ester (PBS) and poly (propylene glycol terephthalate (PTT), and other biological chemical fiber varieties.
Multidisciplinary cross fusion is the development of the industry technical characteristics. In conventional materials to design is important to the development of biological base of chemical fiber technology is proposed. From the traditional biological discipline and its relevant physical, chemical discipline penetration to the material, energy, disciplines, composite material science and other fields. Biomass fiber research and related disciplines continue to cross, penetration, a new academic growth point will appear constantly, Beijing chemical university college of life science and technology, dean of the yuan friends that it is a good idea to interdisciplinary work on the development of industry will play a twice the result with half the effort. Said Zhao Qingzhang also, an adviser to the China textile academy of sciences, the development of the biological base of chemical fiber industry to absorb the professionals in the field of textile.
In terms of technical research, compared with large foreign enterprises "deep pockets", domestic related enterprises appear weak. Zheng Zhi art said, for domestic related enterprises, the fight alone, the strength is limited, with the help of power will accelerate the breakthrough of technology research and development. According to China's chemical fiber industry association secretary-general Wang Yuping, "Marine biological base of chemical fiber and its application industry alliance", "PLA/PHA fiber and application industry alliance", "new solvent method cellulose fiber and application industry association, such as technology innovation alliance will be gradually established in the subsequent work. Xinxiang officials also believe the egret chemical fiber, the industry faces on the key technical problems of the generality of the cooperative engagement can accelerate the pace of industrialization.
Technical development talents. To cultivate comprehensive talents for the development of the industry is the major professional institutions. For talents cultivation, deng xiaoping pointed out that a close to the industry development of the biological base of chemical fiber materials is indispensable. His advice to each big colleges can make a copy of this aspect of the teaching material, cultivating the learn more cutting-edge technology for the development of industry.
