Duan Xiaoping: Five years, science and technology casting chemical fiber power

(According to the recording of the speech of the first chemical fiber technology conference) Duan Xiaoping Technology is the weapon of the country, the country relies on the strong, the industry depends on the prosperity, the enterprise relies on winning. Under the current national science and technology innovation strategy, under the guidance of General Secretary Xi Jinping of the "Science and Technology Association" on the spirit of "scientific and technological innovation", how to use the Chinese chemical fiber industry at the special turning point of the convergence of "two years" The basis of the development of chemical fiber technology during the “Twelfth Five-Year Plan” period? How to give play to the leading role of scientific and technological innovation and take the road of scientific and technological innovation and development. By 2020, the technological level of China's chemical fiber industry will reach international advanced or international first-class. I. The “Twelfth Five-Year Plan” will strengthen the foundation of science and technology and help the rapid development of the chemical fiber industry. During the “Twelfth Five-Year Plan” period, the Chinese chemical fiber industry has formed a complete industrial chain supporting system, including the corresponding scientific research, personnel training and equipment manufacturing departments; Leading equipment and technology in the field of fiber production; products ranging from conventional chemical fibers, high-performance chemical fibers to bio-based chemical fibers, making it the country with the widest product coverage and applications. These achievements have laid a solid foundation for the future development of the chemical fiber industry, and created favorable conditions for the industry to achieve transformation and upgrading, innovation and development. (I) The industry's overall technological progress has significantly improved the development of “super-capacity and high-efficiency flexible differential polyester filament complete engineering technology” and “key technology development of high-quality melt direct-spinning ultra-fine denier polyester filament”. The second prize of scientific and technological progress, 13 technologies of “100,000 tons of melt straight-spun polyester industrial yarn production technology” and “1000 tons of polyimide fiber industrialization complete technology and equipment” won the “Textile Light” science The first prize for technological progress, the winning rate of chemical fiber projects is the highest in the textile industry, and fully demonstrates the content of technology in the chemical fiber industry. (II) Significant breakthrough in high-performance fiber industrialization technology In 2015, the domestic high-performance fiber production capacity reached 150,000 tons, and the export volume reached 38,000 tons. The export volume ranked second in the world. Whether fiber can be exported is an important indicator to measure its development level. In the past, our chemical fiber relied on imports. Now we are the world's number one and export is the first. This shows that our production level has improved, and high-performance fiber is also the same, indicating that China is currently The overall technical level of the high performance fiber industry has reached international standards. There is another sentence that can describe our achievements in this respect. We have used 5 to 10 years to make up for the gap between high-performance fiber and developed countries in 30-40 years, which is important for the further improvement of the high-performance fiber industry. significance. (III) New progress in bio-based chemical fiber and raw material core technology In 2015, the total capacity of new bio-based fiber reached 400,000 tons. Make full use of agricultural products, crop waste and resources such as bamboo, hemp and fast-growing forest to achieve renewable, degradable and recyclable. One thing is worthy of our pride. Almost all high-performance fiber and bio-based chemical fiber are produced in China. China has become the country with the widest coverage of high-tech fiber production. (IV) Significant achievements in green manufacturing technology promotion and recycling system construction The chemical fiber industry is actively promoting green manufacturing, promoting advanced green manufacturing technology, energy saving and recycling technologies, and accelerating the elimination of high energy consumption, high pollution and low efficiency. Production process and equipment. During the “Twelfth Five-Year Plan” period, the chemical fiber industry launched ten energy-saving and emission-reduction technologies, successfully completed the energy conservation and emission reduction targets of the “Twelfth Five-Year Plan”. The total output of recycled fiber is close to 5 million tons, accounting for 10% of the total chemical fiber production in China. , accounting for 80% of the total scale of global fiber recycling. (V) Significant progress in the construction of science and technology innovation support system The chemical fiber industry currently has five innovation alliances, such as chemical fiber industry technology innovation strategic alliance, chemical fiber regeneration and circular economy industrial technology innovation strategic alliance. Among them, the chemical fiber industry technology innovation strategic alliance is the A-level alliance. The National Science and Technology Ministry pilot alliance; there are 12 national-level enterprise technology centers and 45 provincial-level enterprises. There are national key medical laboratories and research institutes with public testing service platforms in universities, and the proportion is also the largest in the textile industry. The standardization system was rapidly promoted, and 37 national standards, 182 industry standards and 32 association standards were revised. In promoting the integration of the two industries, the dominant enterprises actively built modern intelligent factories, intelligent workshops, and machine substitutions; Chemical Fiber Industry Association - Heng Yi Fund" academic awards commended papers 356 and so on. (VI) Three major problems that the industry needs to face directly Although the chemical fiber industry has made great achievements during the “Twelfth Five-Year Plan” period, there are still three major problems: 1) The original innovation capability is insufficient, the enterprise innovation vitality and motivation are not strong, and the R&D investment is insufficient. , has not yet formed a dynamic technological innovation system, research and development fragmentation, and is not strong support for cutting-edge technology and key technology innovation. We are looking at these problems and trying to solve them. The problem started from 2011 to 2012. The original intention of setting up the China Chemical Fiber Industry Association and Hengyi Fund Excellent Paper Award is to do this. We have not had much experience to copy. Taking the road of independent research and development and innovation to promote technological progress, without the support of basic theory, it is impossible to have leap-forward technological progress. Practice has proved that what we advocate and do is in line with national policies. 2 The innovation model combining production, education and research is not deep enough. The next step is to enhance the participation and discourse power of enterprises in the innovation alliance, so that enterprises can play a greater role in the alliance. 3 is a shortage of innovative technology leaders. In particular, small and medium-sized enterprises need to strengthen their ability to innovate because of the lack of funds and talents. II.13: Launching the engine of scientific and technological innovation, casting a strong chemical fiber country Under the new economic normal, the development of the textile industry faces two major tasks: first, the adjustment of international division of labor and overseas layout, and second, the structural reform of the supply side. For the chemical fiber industry, it is more important to focus on supply-side structural reforms. The “three-product” strategy put forward by the Ministry of Industry and Information Technology is actually the concrete practice of supply-side structural reform in the industrial field. The “three-product” strategy cannot be separated from scientific and technological progress, technological development varieties, technology to improve quality, and technology casting brands. China's chemical fiber textile industry is still unable to follow the road of French and Italian fashion brands, and must follow the road of technology brands in Germany and Japan. Scientific and technological progress is the top priority of the “13th Five-Year Plan” of the chemical fiber industry. During the “13th Five-Year Plan” period, the chemical fiber industry must adhere to the innovation drive, improve the innovation system, break through the bottleneck constraints, and adhere to the four basic principles of market orientation; The eight major goals of science and technology development; the completion of the ten key tasks of science and technology development. (I) Eight major objectives of science and technology development: 1. Accelerate the development and professional application of differentiated functionalized fibers, emphasize the integration of multiple technologies, enhance the added value of products, establish an efficient new product development and promotion platform, and achieve a differentiated rate of chemical fiber. 65%; 2. Break through a number of key technical bottlenecks in high-performance fiber industrialization, comprehensively improve the quality stability and application performance of high-performance fibers, achieve low-cost, high added value of high-performance fibers and products, enhance product competitiveness, and high performance. Effective fiber production capacity reached 260,000 tons; 3. Break through a number of key technologies and equipment for bio-based fiber industrialization, promote the development of bio-based fibers and their raw materials, and produce bio-based fiber capacity of 900,000 tons; 4. Support a batch of waste polyester Fiber-to-fiber recycling and high-quality technology, waste textile recycling and recycling of chemical industry key technologies, and the total amount of fiber continues to grow, recycling and recycling system is further improved; recycled fiber accounts for 12% of chemical fiber, year The average growth rate reached 15%; 5. Supporting a batch of key technologies for industrial fiber manufacturing Technology, expand the application of chemical fiber in industrial fields, the proportion of chemical fiber for industrial use increased to 33%; 6. Support a number of key technologies for green low-carbon energy conservation and emission reduction in chemical fiber industry, energy consumption per unit, water consumption, and discharge of major pollutants It meets the requirements of national binding indicators and related standards; 7. Has a core technology of independent intellectual property rights, authorizes invention patents to increase by 15% annually, and large and medium-sized enterprises' research and development expenditures account for more than 1.2% of main business income, new product output value The proportion has increased to over 28%, and the construction of industrial innovation platform has further advanced and played a key supporting role. At present, the R&D expenditure of large and medium-sized chemical fiber enterprises accounts for 1% of the main business income. Let's take a look at Huawei. In 2015, the basic research and R&D investment is 9 billion US dollars, accounting for 15% of the total annual revenue. In the future, the proportion of its investment will increase to 20% or even 30%. Huawei has 26 R&D centers around the world. Most are located in Europe. The direction in which future chemical fiber companies go is also determined by technology and R&D investment. 8. Have a batch of chemical fiber safety evaluation, basic general standards, further optimize the chemical fiber standard system structure, formulate chemical fiber group standards, enhance international standardization capabilities, and lead the formulation of some international standards. (II) Ten key tasks of science and technology development The ten key tasks of chemical fiber technology development during the “13th Five-Year Plan” period are: (1) strengthening basic theoretical research, (2) overcoming major key common technologies in the industry, and (3) promoting general fiber intelligence Convergence, (4) improve the quality of high-performance fiber, (5) expand the application of bio-based chemical fiber, (6) strengthen the comprehensive utilization of independent innovation of recycled recycled fiber (7) develop green manufacturing technology, (8) improve the application level of information technology, (9) Improve the standard system and the clean production evaluation system, and (10) build a professional talent team. Among them, it is our key focus to overcome the key common technologies in the industry, improve the quality of high-performance fibers, develop green manufacturing technologies, and improve the application level of information technology. 1. Conquering the five key common technologies in the industry First, we will tackle high-performance fibers and focus on low-cost, high-stability manufacturing of key technologies and equipment engineering technologies. The second is to overcome the key technologies of high-efficiency flexible and integrated manufacturing of general-purpose fiber, the key technology of low-cost preparation of new polyester industrial filament, the new function and the high-efficiency and controllable large-scale preparation and application technology of intelligent fiber and nanofiber. The third is to overcome the bio-based raw materials and bio-based fiber green processing technology and equipment integration technology to replace petroleum resources; the high-efficiency continuous polymerization technology of bio-based synthetic polyesters such as PLA, PDT and PTT; the key to bio-based polyol engineering and industrialization Technology; biomedical fibers and products, biodegradable fibers and products, bio-based fiber new resources, efficient cleaning and key technologies for high value-added products. The fourth is to overcome the key technologies of high-quality recycling of recycled fiber. The fifth is to overcome key technologies such as digital, intelligent, chemical fiber equipment and manufacturing; large-capacity multi-batch product information automation and product traceability. The five key common technologies are related to the overall technical level of the industry. If we solve it well, we will take a step toward the strong chemical fiber country; if we solve it all, we will become a strong chemical fiber country. (1) Green manufacturing technology: 8+3 Green manufacturing technology: 8+3, that is, 8 energy-saving emission reduction technologies and 3 green fiber manufacturing technologies, 8 refers to the process, and 3 refers to the result. The eight energy-saving and emission reduction technologies include: green pulping technology, one-step nitrogen extraction technology for regenerated cellulose fiber, organic matter extraction technology in polyester esterification wastewater, polyester non-ruthenium catalyst polymerization technology, high-performance fiber and product recycling technology. Waste textile chemical recycling technology, recycled polypropylene direct spinning technology, air conditioning system energy-saving integration technology. Among these eight, polyester non-ruthenium catalyst polymerization technology is very important, because the 40 million tons of polyester production accounts for 80% of the total chemical fiber production. More than a year ago, there was a heavy metal over-standard event in the Wujiang area. Although there is no direct evidence to show that it is related to our catalyst, it must be paid enough attention to us, so this technology should be promoted in the industry. Followed by high-performance fiber and product recycling technology, high-performance fiber will usher in great development during the 13th Five-Year Plan period, while high-performance fiber is resistant to acid, alkali and high temperature, and is less prone to natural degradation in natural environment, and is not easy to recycle. It is more harmful to the environment after being discarded, so its recycling is very important. The three green fiber manufacturing technologies include: raw liquid coloring fiber, focusing on perfect color and focus on fashion trends; bio-based chemical fiber, the most important of which is polylactic acid, which is most likely to be a substitute for conventional fiber. Lactic acid fiber heat resistance and fabric dyeing technology; recycling and recycling of chemical fiber, the focus is on taking the road of high quality and expanding the application field. During the "Thirteenth Five-Year Plan" period, China's economy entered a new normal and faced multiple pressures. As far as the chemical fiber industry is concerned, resources and environmental carrying capacity have the greatest pressure. Only by actively improving and upgrading can we avoid being forced to shut down. (2) Major technological breakthroughs: 3+1 Major technological breakthroughs: 3+1, ie 3 breakthrough target technologies and 1 possible breakthrough target technology. The three breakthrough target technologies have achieved major technological breakthroughs in the high-end production and application of new solvent-based cellulose fibers, bio-based synthetic fibers, and high-performance fibers. The new solvent cellulose fiber is the most important of the three technologies, because in the future it is likely to replace the market space of viscose fiber, which now has an annual output of 3.5 million tons. At present, some enterprises have successfully developed this kind of fiber, and basically achieved stable production. The current price is 18,000 yuan/ton, and the conventional viscose fiber is 14,000 yuan/ton. In the near future, when the 30,000-ton production line is put into production. At that time, the cost is likely to drop to 14,000 yuan / ton, when its replacement effect is very obvious. The current breakthrough in this fiber is Lyocell fiber low-cost industrialization technology, solvent localization and recycling and purification technology; bio-based synthetic fiber should focus on solving the production technology of PLA, PTT, PDT, PA56 and other fibers; high-performance fiber high-end production With the application of national major projects such as automobile lightweighting and large aircraft manufacturing as an opportunity, we will focus on high-performance fiber and composite material production technology. One possible breakthrough target technology refers to nylon melt direct spinning technology. With the advancement of technology, this seemingly unlikely technological breakthrough is now possible. Once the technology breaks through, the nylon industry may grow faster than other conventional synthetic fibers. 2. Improve the application level of information technology. Informatization technology includes four aspects: service networking, Internet of Things, cloud computing, big data, Internet of affairs, information and communication technology, and Internet platform, enabling the Internet and the chemical fiber industry to deepen integration and create new The development of the ecology, the other three aspects of the chemical fiber industry involved less. From the perspective of value chain, the chemical fiber industry is mainly used in production and manufacturing, and is at the low end of the value chain. It involves less research and design and sales in high-end. From the application stage, the chemical fiber industry is now in the process. In the process of transforming the production link to the transformation of the sales link, the application of information technology from the industrial synergy is still far away. In the future, we should improve the application level of information technology from the following three aspects: First, apply information technology and advanced measurement and control technology to the whole process management of chemical fiber manufacturing. Development of production-oriented manufacturing execution systems (MES), ERP information systems for enterprise management, and IoT systems for supply chain and downstream e-commerce service platforms and marketing management. Strengthen the development and application of functions such as online detection, remote diagnosis and operation and maintenance. Study the application of big data technology in production
