The key to upgrading the chemical fiber industry is technological progress

The focus of competition in the global fiber economy has gradually shifted from the product competition, which mainly relies on the comparative advantage of the labor force, to the competition based on the ability to rely heavily on science and technology innovation. For China's chemical fiber industry, it is faced with the key period of industrial upgrading from quantitative expansion to quality and efficiency. The key to realizing this kind of industrial upgrading is to improve the technological level of the industry and accelerate the pace of technological progress.
Zheng Zhiyi, chairman of the China Chemical Fiber Industry Association, pointed out that the technological advancement of China's chemical fiber industry in the next few years should start from the following aspects:
First, we must use high technology to transform and upgrade the traditional industries in terms of processes, equipment, process control and management.
High-tech can be applied to the entire production process of chemical fiber products, including polymerization, reaction mechanism, chemical process, process control, catalytic theory and catalytic material screening manufacturing, fine additives, additives, oil additives, fine dispersion, fine temperature control system , online detection technology and so on. The problems in these areas are wide-ranging and it is the easiest to obtain practical benefits.
In view of the current low value-added products, we should make full use of high technology and vigorously develop differentiated and functional products to increase the added value of products. From the analysis of the development of differentiated commercial varieties, China has concentrated more on specifications and cross-sections, and there is a large gap between multi-component, multi-performance, and multi-functionality. High-tech offers quick and low-cost possibilities to reduce such gaps. The application of high-tech to develop differentiated and functionalized fibers must be combined with the development of downstream products to effectively support the development of market demand.
For energy-saving emission reduction and environmental friendly requirements, we must vigorously develop green fiber and recycled fiber. Among them, we must develop biodegradable fiber such as viscose fiber and acetate fiber, reduce secondary pollution to the environment, accelerate the development of recycled polyester staple fiber, renewable polyester filament, continuously improve the level of technical equipment, improve product quality, and actively Participate in international competition and increase the proportion of these fibers in the total volume.
Second, we must develop high-tech fiber, and key varieties must achieve industrial production during the "11th Five-Year Plan" period.
At present, although the total amount of high-tech fiber market is limited, it has significant implications for the operation and development of the national economy because of its long industrial chain and wide supply chain. In the coming years, the focus of China's development of new and special fibers includes carbon fiber, aramid fiber 1414, PTT fiber, PPS fiber, and ultrahigh molecular weight polyethylene fiber. Zheng Zhiyi pointed out that high-tech fiber technology has a high threshold, is capital-intensive, has a relatively small market capacity, and involves a small number of enterprises. Therefore, it needs to fully grasp the situation, moderate publicity and guidance, pay attention to case service, and strive for national policies to support and strengthen planning.
Third, we must vigorously develop biomass engineering technology in light of resource constraints such as oil and natural gas.
In the coming years, the development priorities of the biomass engineering technology of the chemical fiber industry include polylactic acid fiber materials, solvent-based cellulose fibers, research and development of bio-based polyol technology, industrialization of reusable multi-class fast-growing wood application technologies, and multi-protein fiber technology Research and development. The bamboo pulp fiber and hemp pulp fiber series should achieve the industrialization target of 100,000 tons and 10,000 tons, and strive for breakthroughs in the industrialization of bio-based polyols and plant straw chemical pulp.
Fourth, we must continue to strengthen theoretical research on the basics and applications of chemical fiber, and strengthen engineering capabilities.
In the past, engineering forces with localization as their goal effectively solved problems such as the disconnection of technology and products, the inability of technology and equipment to progress simultaneously, and the low-cost investment and operation. In the future, the focus of the chemical fiber industry's strengthening of engineering capabilities will include: upgrading the existing large-scale domestically produced complete sets of technical equipment and engineering standards, accelerating the localization of major technical equipment in the industry, strengthening the development of key equipment and components for high-tech fiber, and strengthening process software and Equipment integration engineering development.
Fifth, we must pay attention to international cooperation in the context of global economic integration.
In particular, Zheng Zhiyi pointed out that in the future, the international cooperation of China's chemical fiber industry will focus on joint ventures and cooperation and continue to introduce advanced international chemical fiber production technology, equipment, and process control systems to improve quality, reduce consumption, and optimize technology and product structure. We must cooperate in the research and development or introduction of key technologies to achieve breakthroughs in differentiated and functionalized fiber industrialization and achieve differentiated development goals.
