Technology is the primary productive force, and technological innovation is crucial to driving the textile and chemical fiber industry to achieve high quality development in the new era.

In 2018, the China Chemical Fiber Technology Conference was held in Pingdingshan, Henan Province. The conference was jointly sponsored by the Department of Environment and Textile Engineering of the Chinese Academy of Engineering, the China Chemical Fiber Industry Association, the China Textile Engineering Society, and the Pingding Municipal People's Government. The theme was "Fiber New Vision - Zhirong Technology, Creation and Future" In the context of the new era, the significance of technological innovation in China's chemical fiber industry, the focus of scientific and technological innovation in the chemical fiber industry during the 13th Five-Year Plan period, and the key technologies that need to be overcome, how to cooperate with industry, academia and research, and promote the industrialization of scientific and technological achievements. The topic was explored in depth.

Building a strong chemical fiber country needs scientific and technological innovation support

From a macroeconomic perspective, what corresponds to “stock premium” is that economic development shifts from high-speed growth to medium- and high-speed growth, supply-side structural reforms and de-leverage. There are two inspirations for the chemical fiber industry: First, how to make the existing industry stronger, not bigger. In the past, it was possible to become stronger when it was bigger, but the order of strengthening and expanding should be adjusted now. The development of the industry should be oriented towards high quality and high level. Second, under the existing competitive landscape, leading enterprises will Agglomeration effect.

How is technology first understood? Under the background of the new era, the textile industry has proposed a new orientation of “innovation-driven technology industry, culture-led fashion industry, and responsibility-oriented green industry”. Among them, technology is ranked first.

Duan Xiaoping pointed out that the chemical fiber industry has made great achievements in the development of science and technology: the key raw material preparation technology has achieved overflying and broke through resource constraints, forming China's unique bamboo fiber, bio-based pentaamine, adipic acid and chitosan preparation. System; functional fiber preparation technology to achieve overflying, development of single-layer graphene preparation and modification, composite multi-functional high-efficiency preparation, multi-component copolymerization modification technology; high-performance fiber preparation technology to achieve overflight, overcome dry-jet wet spinning high Performance carbon fiber industrialization key technologies and independent equipment, from scratch; promote the integration of military and civilian, has formed a high-level fiber new material military supporting system covering industry organizations, universities, scientific research institutions, backbone enterprises and demanders, in the single The company provided important support and guarantee for the production of weapons protection, equipment support and camouflage anti-jamming weapons. The China Chemical Fiber Industry Association and the Military Equipment Research Institute of the Logistics Support Department undertook the establishment of a military-civilian dual-use chemical fiber standard system project.

Duan Xiaoping further pointed out that green is also the new positioning of the textile industry, and the chemical fiber industry wants to achieve green development, it is inseparable from the support of green manufacturing technology, and green manufacturing technology includes energy-saving emission reduction technology and green fiber manufacturing technology. Among them, energy-saving and emission reduction technologies include green pulping technology, one-step nitrogen extraction technology for regenerated cellulose fibers, organic matter extraction technology in polyester esterification wastewater, polyester non-ruthenium catalyst polymerization technology, high-performance fiber and product recycling technology, and waste. Textile chemical recovery technology, recycled polypropylene direct spinning technology, air conditioning system energy-saving integration technology. Green fiber manufacturing technologies include raw liquid coloring fiber technology, bio-based chemical fiber technology, and recycled chemical fiber technology.

“Innovative development is the key to the transformation and upgrading of the industry. After nearly 20 years of rapid development, China’s chemical fiber industry has achieved such results today, all because of the path of innovation and development. These achievements are largely attributed to the hospital. With the support of relevant state departments, the school and scientific research units insist on innovation, while enterprises transform these innovative technologies into industrialization. Next, China still has a long way to go to realize the transformation from a chemical fiber country to a chemical fiber power. In general, China's chemical fiber industry has an absolute advantage in terms of production capacity, but there is still a gap between high-tech and high-performance fiber in comparison with developed countries. However, in order to achieve the goal of building a chemical fiber power in a short period of time, the key is to It is to strengthen technological innovation," said Jiang Shicheng, an academician of the Chinese Academy of Engineering.

Chemical fiber industry technology development includes 10 key points

The key points of science and technology development in China's chemical fiber industry include ten key tasks, including strengthening basic theoretical research, overcoming major key common technologies in the industry, promoting the integration of general fiber intelligence, improving the quality of high-performance fibers, expanding the application of bio-based chemical fibers, and strengthening the recycling of recycled fibers. Innovate comprehensive utilization, develop green manufacturing technology, improve the application level of information technology, improve the standard system and clean production evaluation system, and build a professional talent team.

Among these key tasks, Duan Xiaoping emphasized the importance of the first two items. He said: "The ZTE incident has given us the enlightenment that the industry must overcome major key common technologies. China's chips are precisely because of the lack of basic research, and they will not be subject to the key common technologies of the industry."

According to Duan Xiaoping, the major key common technologies that the chemical fiber industry needs to overcome include five aspects.

The first is to overcome the high-cost fiber low-cost, high-stability manufacturing key technology and equipment engineering technology.

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 efficient 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, new resources for bio-based fibers, 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 and intelligent chemical fiber equipment and manufacturing; large-capacity multi-batch product information automation and product traceability.

Duan Xiaoping also pointed out that technological innovation also needs the support of the standard system. Since the “Thirteenth Five-Year Plan”, the basic support role of the standardization work in the chemical fiber industry in the high-quality development of the chemical fiber industry has become more and more obvious, the standard effectiveness, advancement and applicability have been further enhanced, and the industry's green development and technological innovation have been deeply integrated. Create a new situation in which the market norms have the standard to follow, the innovation drives the standard, and the transformation and upgrading have the standard support.

It is precisely because of the importance of standard work. During the conference, the Chemical Fiber Association also announced the establishment of the Standardization Technical Committee of China Chemical Fiber Industry Association.

“Standards can be taken first. The number and types of products in the chemical fiber industry have increased in the past few years. The standards at that time could not meet the needs of the development of the industry. So around 2011, the China Chemical Fiber Association launched a study on the group standards of the association. Moreover, from the perspective of the international market, foreign countries mainly rely on non-governmental standards and third-party standards, and China will sooner or later be in line with international standards.” Duan Xiaoping emphasized.
