2023/7/10
As the core support for stable development and continuous innovation in China's textile industry chain system, chemical fiber industry is an international competitive advantage industry and an important part of new material industry. In the past decades of rapid development, China's chemical fiber has gradually shifted from following and running into a new stage of leading, but it is also facing increasing competitive pressure, and the demand for structural adjustment and industrial upgrading is more urgent.
In China's economy from high-speed growth into a new stage of high-quality development, chemical fiber industry should be how to continue to maintain and enhance competitiveness? In the recently held China Chemical Fiber Science and Technology Conference, experts from the chemical fiber industry focus on the construction of modern industrial system of textile and chemical fiber, disseminate the latest technological achievements of fiber science and technology, and discuss the new situation of the chemical fiber industry, high-end, green, sustainable development road.
Scientific and technological innovation leads the new development of the industry
At present, China's chemical fiber industry has formed barriers to entry through refining and chemical integration and volume advantages; Chinese enterprises also follow the concept of green sustainability, production of recycling, green, biodegradable and other categories of sustainable fibers by the market recognition.
How to further promote the high-quality development of China's chemical fiber industry?
Duan Xiaoping, vice president of the China Textile Industry Federation, believes that we should pay attention to the global macroeconomic trends and prevent operational risks; we should pay attention to sustainable development and strengthen the construction of green brands; we should adapt to the economic "shift" and cultivate the core competitiveness of enterprises; and we should pay attention to the security of the industrial chain supply chain.
In the view of Zhu Meifang, academician of the Chinese Academy of Sciences, in the face of the severe and complex international environment, the chemical fiber industry to open up new areas of development of the new track, to lead the new development of the global chemical fiber industry, fundamentally, or rely on scientific and technological innovation. Based on this, we should focus on consolidating basic research, focus on strengthening cooperation between industry, academia and research, and focus on playing the role of the industry platform.
Ministry of Industry and Information Technology, Consumer Goods Industry Division, Textile Division Director Yu Kun said, to strengthen the scientific and technological leadership, promote industrial innovation and upgrading; the implementation of the "double carbon" goal, promote industrial green transformation; accelerate the integration of digital reality, promote industrial transformation and upgrading.
Technological breakthroughs power fiber greening
After years of development and accumulation, China's chemical fiber industry has basically completed three aspects of the layout.
First, high-performance fibers and composites for aerospace, national defense and military industry, high-end equipment and advanced manufacturing; secondly, for a large number of fiber materials, giving them functionality and intelligence, that is, multi-functional fibers; thirdly, alternative petroleum resources, bio-based fiber materials, that is, environmentally friendly and bio-fiber materials. These three aspects of the layout as well as the remarkable achievements made to support the construction of China's textile power of the main indicators basically reached.
However, in the face of the new situation, new stage, new changes, China's chemical fiber industry must also look for new starting point in technological innovation, green development and other aspects.
Professor Sun Yize of Donghua University put the focus of technological innovation on three-dimensional knitting technology. He pointed out that three-dimensional knitting belongs to the single-cell structure, good mechanical properties, suitable for a variety of curved bodies, shaped structural parts, its material loss is small, high degree of automation, is currently both composite material preform and production cost cost-effective production mode. In the future, three-dimensional knitting technology will be toward the large size, ultra-thick, high-density curved body three-dimensional knitting technology, large cross-section size three-dimensional knitting technology and other directions.
Wang Rui, professor of Beijing Institute of Fashion Technology, focused on "new technology of flame retardant polyester fiber - carboxylic acid MOFs preparation and application in PET flame retardant". She pointed out that with the increase of flame-retardant fiber production, the pressure of environmental protection and flame retardancy is even greater, and there is an urgent need to develop low-carbon and environmentally friendly flame retardants. In the future, her group will comprehensively promote the design and development, engineering and scale-up of MOFs flame retardant fibers.
In addition to work on improving the performance of fibers and other aspects, many experts will also focus on scientific and technological research and development on the greening and sustainability of fibers.
Wang Yuzhong, academician of the Chinese Academy of Engineering that the green development of chemical fiber industry, one is the research and development of green catalytic technology into fiber polymers, spinning, processing, functionalization of additives and modifiers green technology; biomass as raw material for the production of textile fibers in line with the demand for low-carbon development, the future need to develop its green production technology, enhance the cost-effectiveness of products. Secondly, the existing textile fiber materials, should develop its waste recycling and upgrading recovery of new technologies, not only to reduce fossil energy consumption, but also reduce the waste to the environment, in line with the demand for green and low-carbon development; focusing on the development of waste cotton high efficiency decolorization, clean pulping and spinning technology, as well as waste polyester and its various blended products, green and efficient chemical depolymerization technology. Third, for the new design and synthesis of fiber-forming polymers, in addition to consider the use of performance, should also consider the environmental protection of synthesis, recycling, easy to recycle and functional high value, to promote the development of differentiation of China's textile industry, enhance industrial competitiveness.
"Waste textile recycling and reuse is an important component of realizing low-carbon and sustainable development both in China and the world." In the view of Wang Huaping, researcher of Donghua University, it is necessary to promote the industrialization and development of new technology of waste textile recycling from the aspects of biological depolymerization and regeneration technology, microwave and other process-enhancing technology, and chemical conversion and fusion and regeneration technology; and to start to strengthen the high-level modern waste textile processing industry system from the perspectives of industry chain upgrading, technology integration, factory intelligence, and multi-dimensional synergism.
