Chasing “intelligence” and “green” to move towards high-end, the chemical fiber industry actively creates “hard advantages”
Facing the new development pattern and new challenges, the positioning of the chemical fiber industry is also undergoing profound changes. In April this year, the Ministry of Industry and Information Technology and the National Development and Reform Commission jointly issued the “Guiding Opinions on the HighQuality Development of the Chemical Fiber Industry”, pointing out that the chemical fiber industry is the key to the stable development of the textile industry chain. and the core support of continuous innovation. It is an industry with international competitive advantages and an important part of the new materials industry. Xian Nong, a first-level inspector of the Industry Department of the National Development and Reform Commission, said at the 28th China International Chemical Fiber Conference, “This positioning is the basis for an in-depth analysis of the new historical stage of my country’s chemical fiber industry and a comprehensive understanding and grasp of the important role of the chemical fiber industry. This is a new judgment on the positioning of the chemical fiber industry, which will give new tasks and put forward new requirements for the development of the chemical fiber industry.”
Under the new development situation, how should the chemical fiber industry consolidate its advantages, make up for its shortcomings, and strengthen its weaknesses? He Yaqiong, director of the Consumer Goods Industry Department of the Ministry of Industry and Information Technology, said that the first is to deepen the supply-side structural reform and implement the “three-product” strategy of increasing varieties, improving quality, and creating brands. It is necessary to improve the resilience of the supply system, lead and create demand with high-quality supply, and promote industrial upgrading, product upgrading, and consumption upgrading. It is necessary to attach great importance to the role of “brand”, expand the influence of “Chinese FiberFashion Trends” and “Green Fiber”, and enhance consumers’ awareness of Chinese fiber and enterprises, Further unite clothing and home textile enterprises to strengthen the cultivation of advantageous brands, expand demand and maintain the safety and stability of the supply chain through brand building. The second is to accelerate the intelligent green transformation to consolidate and enhance international competitiveness. We must pay more attention to high-end, intelligent, and green development, and win the market with hard advantages such as quality and price. Let green and low-carbon become a new competitive advantage in the chemical fiber industry, and let green and low-carbon fiber products empower textile and apparel products. Promote the collaborative innovative application of various fiber raw materials and improve the resilience and safety level of the industrial chain and supply chain. The third is to promote the collaborative innovation and mutual empowerment of chemical fibers and natural fibers, strengthen the development of new technologies and new products, and promote the positive organic linkage and mutual support of the chemical fiber and cotton chains. , Improve the resilience and safety level of the industrial chain and supply chain. The fourth is to strengthen international cooperation in industry and trade and build a new development pattern of mutual promotion of domestic and international dual cycles.
Seize the new positioning to make high-quality development more resilient
At present, the global economic and industrial development pattern is undergoing profound changes. my country’s chemical fiber industry is facing many development pressures and challenges such as rising crude oil prices, sluggish downstream demand, and declining corporate efficiency. Against this background, how should the chemical fiber industry promote high-quality development? ?
Xu Kunyuan, former deputy minister of the Ministry of Textile Industry and former vice president of the China Textile and Apparel Federation, pointed out that chemical fiber now accounts for more than 80% of textile raw materials. At the same time, chemical fiber It is also an important basic material for industrial textiles. The chemical fiber industry is not only an important livelihood industry, but also a strategic emerging industry. Therefore, the chemical fiber industry must pioneer and innovate, adjust its structure, develop high-tech fibers, optimize the industrial system, unite the upstream and downstream industrial chains, and gradually achieve the goals of high-end, informatization, intelligence and green development, and achieve high-quality development.
“After the development during the ‘Thirteenth Five-Year Plan‘ period, my country’s chemical fiber industry continues to deepen the supply-side structural reform, continuously promotes industrial structural adjustment, and further consolidates the role of my country’s textile industry in The status and role of the industrial system and the global fiber industry have laid a solid foundation for comprehensively building a strong chemical fiber country. The ’14th Five-Year Plan’ is an important period of opportunity for comprehensively building a strong chemical fiber country and achieving high-quality development. The chemical fiber industry must fully implement new developments concept, vigorously implement the “Guiding Opinions on the High-Quality Development of the Chemical Fiber Industry”, strengthen independent innovation of key technologies and equipment for new fiber materials, accelerate digital transformation and upgrading, promote green and low-carbon transformation, and build a high-end, intelligent, and green modern industry in the chemical fiber industry. system.” said Jiang Shicheng, an academician of the Chinese Academy of Engineering.
Regarding the high-quality development of the chemical fiber industry, Xia Nong made three suggestions: First, focus on improving the resilience and safety level of the industrial chain and supply chain. It is necessary to put the enhancement of the resilience and competitiveness of the industrial chain in a more important position, and strive to create an independent, controllable, safe and reliable industrial chain and supply chain. In particular, the key points related to the stable development of the industry must make up for the shortcomings and enhance autonomyIntellectual property rights and substitution capabilities ensure the stability and smoothness of the industrial chain and supply chain. The second is to focus on building a new development pattern for the industry. It is necessary to increase the added value and brand influence of my country’s fiber products through high-quality development, and enhance the global value chain status of my country’s chemical fiber industry; it is necessary to work from both ends of supply and demand, not only expand effective demand, form a strong domestic market, but also promote productionTransformation and upgrading to consolidate and enhance industrial competitive advantages. The third is to focus on promoting the green, circular and low-carbon development of the industry. To deal with industry development wellThe relationship between development and carbon reduction, coordinate and orderly promote carbon peak work, study and formulate a “dual carbon” strategic roadmap for the chemical fiber industry, clarify the industry’s carbon reduction implementation path, and promote the formation of green and low-carbon production methods and lifestyles.
Finding new growth points and empowering new tracks with new materials
Under the new development trend, where is the new track for the chemical fiber industry?
Zhu Meifang, academician of the Chinese Academy of Sciences and dean of the School of Materials at Donghua University, pointed out that the fiber industry has entered a new track, and the raw materials, polymerization, processing, and forming processes have been endowed with technology and environmental protection font>, the new concept of intelligence, characterized by intelligence, super performance, and green, can have a highly penetrating, disruptive, and transformative effect on traditional industrial clusters A new generation of fibers will be the research direction.
Taking carbon fiber as an example, in recent years, the demand for carbon fiber in the new energy field has grown rapidly, the demand for domestic carbon fiber has increased significantly, and the profit margins of domestic carbon fiber companies have continued to increase. In the future, domestic carbon fiber will have broad application prospects in high value-added fields such as aerospace, pressure vessels, carbon/carboncomposites, and companies with independent intellectual property rights and continuous innovation capabilities will Take advantage of future competition.
Carbon fiber is usually combined with other materials such as resin to form composite materials, which can be used to prepare structural materials, functional materials or materials with both structure and function. Carbon fiber prefabricated body, also known as carbon fiber fabric, is a composite material reinforcement with a specific shape formed by weaving, weaving, stitching, needle punching, etc. using carbon fiber as raw material. It is the “key reinforcing base material” of composite materials. . The structure and performance of prefabricated bodies directly affect the structure and performance of composite materials, and is a key basic material for advanced composite materials.
Miao Yunliang, chairman of Jiangsu Tianniao High-tech Co., Ltd., said that carbon fiber prefabricated bodies can be divided into two categories: flat fabric prefabricated bodies and three-dimensional fabric prefabricated bodies according to their structures. Among them, three-dimensional fabric preforms can be divided into 2.5D woven, three-dimensional weaving, suture, puncture, acupuncture, etc., and acupuncture carbon fiber preforms are widely used. Compared with 3D braided preforms, needle-punched preforms have the advantages of uniform pore distribution, easy dense molding, high in-plane and inter-layer strength, high production efficiency, low cost, and easy mass production. Its application areas include aircraft carbon brake discs, single crystal thermal equipment thermal field materials such as heating elements, heat shields, crucibles, rocket engine combustion chambers, nozzles, etc. For example, needle-punched prefabricated bodies have been used in large quantities in a full range of domestic aircraft models, including C919 and ARJ-21.
Strengthening international cooperation towards a new green era
Although the global economic recovery is not as good as expected, the international situation is more uncertain, and the business environment is becoming more difficult, experts at the meeting all believe that we still live in a globalized and interconnected world, and cooperation is indispensable.
Frédéric Van Houtevu, Chairman of the European Manmade Fibers Association, said that despite facing various uncertainties, the global (especially Asian) manmade fiber industry has recovered relatively quickly and output has continued to grow. Regarding the overall development trend of the industry in the future, he believes that the first is to continue to promote green development in production and consumption, such as developing clean production processes and sustainable products; the second is to accelerate the transformation to a new economy, promote digitalization, automation, and intelligence, so that The industry is more adaptable; the third is to maintain competitive advantages such as high quality, specialization, and efficient management structures; the fourth is to continue to innovate in products, production processes, raw materials, etc.; the fifth is to improve supply chain, textile waste recycling, and marine microplastics Conduct extensive international cooperation on issues such as , biodegradation, and unified standards to achieve a win-win situation for the global textile and chemical fiber industry.
Kenichi Tomiyoshi, executive vice president of the Japan Chemical Fiber Association, said that for sustainable development, Japan focuses on six aspects: PET recycling system, “fiber-fiber” recycling system, bio-based chemical fiber, and response to microplastics ( fiber fragments) issues, work on carbon neutrality, chemical substance management. He said that chemical fiber will support the growth of global fiber demand, and Asia’s chemical fiber production accounts for about 90% of global production. Therefore, the Asian chemical fiber industry will play an important role in the sustainable development of the global fiber industry. It is expected that all parties will share information, strengthen cooperation, and increase efforts to solve sustainable development issues.
At present, reducing carbon emissions is a global social consensus. More than 100 countries have proposed or will propose the goals of carbon peaking and carbon neutrality. Liu Yuan, director of the Market and Innovation Development Department of Product Certification Department Six of the China Quality Certification Center, believes that in the context of global green development, green trade barriers will inevitably increase in the future, such as the upcomingEUCarbontariffs will have an impact on Chinese companies’exports. The proposal of China’s “double carbon” goal will lead to revolutionary changes in the advanced manufacturing industry represented by new chemical fiber materials. In the context of carbon neutrality, the entire chemical fiber industry should focus on six technical routes: source reduction, finding alternative energy sources, improving processes, energy conservation and efficiency improvement, recycling, and technological carbon sequestration.
