Key common technologies indicate the development direction of the textile industry
Business News Agency July 14 The Ministry of Industry and Information Technology announced on July 7th the “Guidelines for the Development of Common Key Technologies for Industries (2011)â€, involving 8 key common technologies in the textile industry. Such as imitation cotton polyester fiber and its textile industrial technology, high-tech fiber technology, high temperature filter material technology, high-performance ultra-fine filtration of nano-fiber membrane key manufacturing technologies, new key technologies such as biomass fiber. These key common technologies are of great and far-reaching significance for the textile industry in achieving sustainable development goals and building a strong textile nation.
Specifying the future direction of the industry Key common technologies in an industry often herald the direction of the industry. For example, over-imitation cotton technology is a key technology that has been highly praised by domestic and foreign textile technicians and invested in R&D in recent years. This technology can make chemical fiber very close to natural cotton, and some technical indicators even exceed cotton. In layman's terms, the “ultra-imitation cotton†products, whether visually, tactilely, or functionally (friendlyness, comfort, washability), have the excellent characteristics of both cotton and chemical fiber, such as polyester, reaching cotton and cotton. The effect of cotton. "Super-imitation cotton" products must ensure that cotton has excellent softness and warmth, but also has good mechanical properties, chemical properties, and even anti-static, anti-pilling, anti-bacterial, flame retardant, far infrared, anti-ultraviolet, etc. Features. With the perfection of "ultra imitation cotton" technology, the added value of the product will also increase.
Wang Huaping, deputy dean of the Donghua University Research Institute and director of the Key Laboratory of High Performance Fiber and Products Ministry of Education, believes that “super-imitation cotton†has opened up a new space for the development of the chemical fiber industry. He said that China’s imitation cotton products still have a big gap compared with foreign countries, especially Japan, and the key technology systems and product systems for the processes of polymerization, spinning, weaving, dyeing and finishing of “ultra imitation cotton†products. The standard system has not yet been formed and needs to be strengthened. He suggested that the industry should strengthen the study of the dynamic heat and moisture comfort performance mechanism of cotton-like fibers and products, clarify the product positioning and goals, and carry out imitation of cotton fine denier or ultrafine denier, hydrophilic copolymerization modification, inorganic blend modification, and surface Research on the capillary wicking effect and dynamics, moisture absorption and moisture transfer ability and kinetics of fibers and fabrics such as roughening and cross-section isomorphism lay the scientific foundation for formulating cotton functional test methods and indicators and regulating market behavior. It is understood that in order to alleviate the contradiction between supply and demand of cotton and effectively use excess polyester production capacity, relying on the strategic alliance for technological innovation in the chemical fiber industry, by the end of 2010, the Ministry of Science and Technology gave priority to the “12th Five-Year Plan†national science and technology support program – “Super-synthetic cotton synthetic fiber. And its textile industrialization technology development." The project includes more than 20 units including the China Academy of Textile Science, Donghua University, Yizheng Chemical Fiber Co., Ltd., and Taicang Jinhui Chemical Fiber Industrial Co., Ltd., to jointly participate in the development.
The “12th Five-year Textile Development Plan†for the realization of the goal of becoming a strong nation in textiles will outline the blueprint for the development of China's textile industry in the next five to 10 years. Among them, key breakthroughs in the current major technological bottlenecks that constrain the development of the industry, overcome a number of common key technologies, and improve core technologies and capabilities for independent innovation have become the core tasks of planning. In order to realize a strong textile nation in 2020, we must have independent innovative high-performance fiber products and achieve industrial mass production. These common key technologies represent the technological capabilities of a country. The development of science and technology can not be separated from the participation of textile high-performance fiber materials. Carbon fiber, para-aramid fibers, and high-strength and high-modulus polyethylene fibers are high-tech fiber technologies highlighted in the "Guidelines for the development of industry-key common technologies (2011)". Spacecraft, large aircraft, high-speed rail, new energy and other industries are inseparable from these textile high-performance composite fibers. After several years of efforts, China's carbon fiber industry is becoming a scale of industrialization. Carbon fiber precursors, pre-oxidation fibers, and carbonization technologies have matured. Key equipment such as pre-oxidation furnaces and large-scale carbonization furnaces can be independently produced. Thousands of tons of carbon fiber equipment, small carbon fiber tow (1 ~ 6k) can already be mass production; carbon fiber T700, T800 and other high-strength and high modulus series of technology has been a certain extension; para-aramid kiloton-level industrial technology is continuously improving; The meta-aramid has achieved industrial production, and the total output has exceeded 10,000 tons; the varieties of high-strength and high-modulus polyethylene fibers have been increased, the output has been expanded, and industrialization has been realized.
Some high-tech private enterprises in China have seized the opportunity of national industrial policy adjustment to advance into the field of high-performance fibers. Some powerful large state-owned companies have also increased their capital investment in science and technology. They have played the role of the national team as the main force and marched into the field of high-tech fibers. It can be foreseen that the industrialization and investment scale of high-performance fiber in China will be further expanded and a new textile industry growth level is taking shape. According to report, in order to cooperate with the development of China's large aircraft C919, a domestic private enterprise has successfully developed the aircraft steering steering fiber composite products, and has passed the identification and evaluation of the relevant departments, the indicators meet the design requirements, can meet China's large aircraft The production needs of some key components.
The shortage of resources for development and harmonious coexistence, the expansion of population, and changes in the environment require that a country's economic development must take into account global interests. Changing the mode of growth, focusing on the future, grasping the development trend of the world's textile technology, deploying basic theoretical research and cutting-edge technologies in advance, and laying a solid foundation for the future development of the industry have become the consensus of the industry. The development of the textile industry has always depended on resources such as cotton, sangma, and oil. However, limited resources have caused bottlenecks in the development of the industry, and the original situation has been impossible to maintain. As a result, textile raw materials were expanded to other fields, to the ocean for fiber (algae fiber, chitin fiber), raw material diversification (bamboo fiber, coconut fiber, sugar cane fiber). In addition, energy conservation, emission reduction and green environmental protection are becoming the key to the sustainable development of the textile industry. Therefore, the key technologies for the mass production of high-efficiency ultra-fine filtration nanofiber membranes for seawater desalination, the high-temperature filter materials technology for providing high-temperature filtration materials for thermal power plants, and the key technologies for new biomass fibers have been pushed to the forefront. Tianjin Polytechnic University has devoted many years to the research and development of various membrane materials such as hollow fiber membrane materials. After the Wenchuan Earthquake, it provided facilities to filter polluted water, to reverse osmosis membrane desalination, and to provide double membrane desalination engineering equipment for Singapore. . High-temperature filter materials play an important role in the filtration of harmful particulate pollutants in thermal power plants, because at 200 degrees Celsius, the filter bag fibers must use high-temperature materials, such as polyphenylene ether, polyimide, poly four Vinyl fluoride and other fibers. However, for some time China cannot produce itself and needs to import it. This situation has greatly changed now. Companies such as Sichuan Deyang and Jiangsu Ruitai have made breakthroughs in the production of high-temperature filter bag materials. Jiangsu Ruitai Technology Co., Ltd. has realized the production of polyphenylene ether (PPS) staple fiber, with an annual output of 10,000 tons of PPS staple fiber and 3000 tons of PPS filament. PPS resin and PPS modified material produced by Sichuan Deyang Special New Material Co., Ltd. fill the gap in the industrial production of PPS in China.
With the continuous improvement of key common technologies for textiles, the R&D and industrialization of many key technologies has become an opportunity for the textile industry to cultivate and develop strategic emerging industries. Of course, due to the difficult and long-term research of key generic technologies, the development of key technologies for industrial commons cannot be achieved overnight. However, as the forward-looking and directional technology of the textile industry, especially the key common technologies in basic materials, key processes, core components, and system integration, we must firmly grasp and not relax. Because it represents the future of textiles.
