Exclusive interview with Academician Jiang Shicheng: the high-quality development of chemical fiber should firmly focus on these three areas

At present, the most distinctive feature of China's economic construction in the new era is to lead China's economy to a high-quality development path with the development concept of "innovation, coordination, green, openness and sharing".

China's chemical fiber industry has gone through a bumpy and thorny entrepreneurial road from a "zero" start to today's world chemical fiber power. Today, 70% of the chemical fiber consumed in the world every year comes from China. Chinese chemical fiber enterprises have seized the opportunity of the times with strong, stable and efficient production and manufacturing capabilities as well as product R & D capabilities, and have established the "country of chemical fiber". However, standing at the crossroads of the new development stage, what is the direction of the industry to strive for next? This proposition is asking every chemical fiber enterprise day and night

Recently, the Ministry of industry and information technology and the national development and Reform Commission jointly issued the guiding opinions on the high-quality development of the chemical fiber industry (hereinafter referred to as the Guiding Opinions), giving clear answers and directions. After the release of the document, our reporter connected Jiang Shicheng, an academician of the Chinese Academy of engineering, to have an in-depth understanding of the technological innovation work that should be made for the high-quality development of the chemical fiber industry.

From "following" to "running together" and "leading"

Embrace the future of Chinese chemical fiber

As the "father of dacron materials" in China, it is Jiang Shicheng who enriched the wardrobe of Chinese people who once could only wear cotton and linen; It was Jiang Shicheng who let such a material as "Dacron" fall from the altar of high price imports and enter the life of every ordinary Chinese people; It was the team led by Jiang Shicheng that created the first milestone with the glory of the times in the history of China's chemical fiber development.

Today, China's chemical fiber industry has grown from small to large, and is trudging on the track of high-quality development from large to strong, In this regard, Jiang Shicheng said: "After the development of the 13th five year plan, the scientific and technological strength of China's chemical fiber industry has been greatly enhanced, and the technical level has entered a new stage from 'following' to 'leading' with the world's leading level, which has provided strong support for China's economic development, livelihood improvement, ecological optimization and national security. However, the industry should also be soberly aware that there is still a certain gap between the scientific and technological level of China's chemical fiber industry and the advanced level of foreign countries, mainly It is reflected in that basic theoretical research still needs to be strengthened, the ability of independent innovation still needs to be comprehensively improved, key core technologies still need to be tackled, the construction of multi-level talent team needs to be strengthened, and the industry still needs to continue to work on the road of high-quality development. "

Jiang Shicheng said, "the scientific and technological development of China's chemical fiber industry should, on the basis of fully mastering the current situation, plan and layout key areas and their advanced technologies, strive to make up for the shortcomings of core technologies, master key technologies and common technologies, plan major projects and projects, and improve the sustainable development ability and core competitiveness of the industry."

Jiang Shicheng believes that the next industry development should focus on these three areas: fiber new materials, green manufacturing, and intelligent manufacturing.

Specifically, the development level of new fiber materials is related to the national economy, social development and national security. Next, enterprises need to focus on the technological progress of functional fibers, bio based fibers, high-performance fibers and recycled fibers. In addition, cutting-edge fiber new materials such as nanofibers, smart fibers, biomedical fibers and degradable fibers are areas that need to be focused on for the high-quality development of the industry.

In the field of green manufacturing, Jiang Shicheng said, "green and environmental protection processes, oiling agents, additives and catalysts, green fiber certification, platform system construction and promotion are all topics that need to be tackled for the high-quality development of chemical fiber."

During the "14th five year plan" period, green manufacturing will become the main battlefield for the manufacturing industry to achieve the "double carbon" goal. Achieving carbon peak and carbon neutralization is also an inevitable choice for the future sustainable development of the textile industry. To this end, the Chinese Academy of engineering has set up a "dual carbon development strategy and technology roadmap for the textile industry" consulting project. According to Jiang Shicheng, the project will form a technical roadmap for low-carbon development of the textile industry through the research on the current situation of carbon emission of China's textile industry, emission reduction technologies in key links of the industrial chain, carbon emission coefficient of textile raw materials and carbon emission benefits of recycling of waste raw materials, and put forward policies, measures and suggestions for low-carbon transformation and development of China's textile industry. This is also an important aspect of the high-quality development of the chemical fiber industry.

In addition, in the field of intelligent manufacturing, Jiang Shicheng believes that we should vigorously promote the digital transformation of enterprises and encourage enterprises to build intelligent factories based on big data, artificial intelligence and industrial Internet.

Forging long boards and mending short boards to consolidate the cornerstone of high-quality development

New fiber materials, green manufacturing and intelligent manufacturing are the three key points that Jiang Shicheng pointed out that the high-quality development of the industry needs to focus on. "For these three key areas, I think the industry still needs to further highlight the key points, layout some major science and technology and engineering projects, strengthen scientific and technological innovation and the toughness of the industrial chain supply chain, strengthen basic research, promote applied research, carry out chain reinforcement and chain strengthening, and speed up the solution of the 'neck sticking' problem." Jiang Shicheng said.

For example, Jiang Shicheng said: in the field of new fiber materials, we can focus on the industrialization technology of high-efficiency flexibility of nylon, the industrialization technology of antimony free polyester fiber, the industrialization technology of high-efficiency flame-retardant fiber, and the industrialization technology of medical protective fiber. In the field of bio based chemical fiber, we should focus on the preparation technology of special pulp and NMMO solvent for lysell fiber, and the localization and low-cost preparation technology of important raw materials such as high light purity, high chemical purity lactic acid and lactide. There are many categories in the field of high-performance fibers, which need to be overcome one by one. For example, the preparation technology of large tow carbon fibers above 48K, t1100 grade and m65j grade carbon fibers needs a breakthrough. Para aramid needs to realize the stable and large-scale production of high-strength, high model para aramid, aramid paper, aramid honeycomb materials, and meet the applications in safety protection, optical communication, aerospace, rail transit and other fields. The most important thing of UHMWPE fiber is to break through the research and development of functionality on the basis of high efficiency and low cost, and expand its application in marine breeding, protective clothing, and other fields.

In addition, some ultra cutting-edge fiber products, such as nanofibers, smart fibers, graphene modified fibers, also need to actively overcome technical bottlenecks to achieve a new stage of development.

As for green manufacturing, Jiang Shicheng pointed out that technically, we should focus on the research and development of new technologies of high-quality recycled polyester and energy-saving and low-carbon devices; The research and development of key technologies of green oiling agents, additives and catalysts should be strengthened. At the same time, combined with the "double carbon" strategy, the implementation path of carbon reduction in the industry should be clarified, the research and development of green processes and equipment should be increased, the transformation of cleaner production technology and the promotion of key energy-saving and emission reduction technologies should be strengthened, so as to promote the improvement of the green development level of chemical fiber. In addition, we should focus on promoting the construction of a trusted platform for green fiber products and improving the quantity and quality of green fiber supply.

In the part of intelligent manufacturing, Jiang Shicheng specifically pointed out that we should guide and play the role of leading enterprises in the industry, concentrate resources to build an industrial Internet platform that can serve the chemical fiber industry, promote upstream and downstream enterprises in the industrial chain to realize resource data sharing through the industrial Internet platform, strengthen the connection between supply and demand, and promote the collaborative development and application of the whole industrial chain.

In addition to setting up key projects in key areas, Jiang Shicheng said that basic research has valuable long-term value for industrial development. The industry needs to pay full attention to the role of universities and scientific research institutions, consolidate the theoretical foundation, and provide theoretical support for improving product stability and product performance, so as to lead the future development of high-tech in the chemical fiber industry, consolidate the international competitive advantage of China's chemical fiber industry, and build a chemical fiber power in an all-round way.

Build a high-quality talent team

Gather intelligence and empower high-quality development

High quality talents are the foundation of high-quality development. Jiang Shicheng especially pointed out that the high-quality development of the chemical fiber industry must strengthen the construction of the industry talent team, vigorously cultivate industry academic / technical leaders, establish a database of senior experts in the chemical fiber industry, and promote the construction of innovation teams in the whole industry while guiding the scientific and technological progress of the industry; We should give play to the leading and exemplary role of China Chemical Fiber Industry Association · Hengyi fund and China Chemical Fiber Industry Association · Lvyu fund, and pay attention to the discovery and training of a group of young and middle-aged technical experts, outstanding engineers and outstanding technical workers. We should give full play to the important role of industry training courses, such as the national advanced training course of textile composite talent training project, strengthen the technical exchange and professional integration between the chemical fiber industry and other related industries such as textile, dyeing and finishing, cultivate a group of composite talents, encourage scientific and technological personnel and experts to participate in international scientific and technological cooperation plans and projects, and cultivate composite scientific and technological talents with international vision. At the same time, we should also use Internet technology to strengthen professional knowledge popularization activities.

In addition, Jiang Shicheng also said that the construction of scientific and technological innovation platform will promote the development of scientific and technological innovation of all kinds of talents. The high-quality development of chemical fiber is inseparable from a scientific and efficient innovation system. The next industry should further strengthen the construction of national and provincial innovation centers, laboratories, Engineering (Technology) research centers, inspection and testing centers, and build a scientific and technological innovation system with the combination of industry, University and research, and efficient collaboration, Comprehensively improve the innovation ability of chemical fiber industry.

Finally, Jiang Shicheng pointed out that the high-quality development of the chemical fiber industry not only requires the cooperation of enterprises, universities, scientific research institutes and the whole industrial chain, but also requires the corresponding encouragement and support policies from relevant national departments. In this regard, he suggested that the relevant departments of the state use the existing special fund channels to support the research and development of major technical equipment and key common technologies in the chemical fiber industry in combination with the development trend of the industry. In addition, Jiang Shicheng also suggested that enterprises, scientific research institutes and colleges and universities should pay attention to and strengthen intellectual property management, strengthen the intellectual property awareness of scientific and technological personnel and scientific and technological managers, promote the formation of an atmosphere for the protection of intellectual property, and give full play to the representative role and collective advantages of industry associations in the maintenance of intellectual property rights.
