Academician of CAE Member JiangBecome a forum speech. He said that the National Advanced Functional Fiber Innovation Center has now formed a construction mode of academician team leadership, scientific research team implementation, and deep cooperation in the collaborative innovation of industry, university and research, opening up a new track, injecting new power, and shaping new advantages for the field of advanced fiber materials.

In terms of green technology, the Innovation Center has developed fiber interface treatment technology, antimony free fiber preparation technology, 10000 ton melt direct spinning flame-retardant polyester fiber engineering preparation technology, etc., focusing on breaking through core technologies such as new fiber material development, equipment basic component manufacturing, etc., continuously increasing investment in green low-carbon technology research and development, encouraging in-depth cooperation between industry, university and research, and promoting the application and promotion of green technology in the fiber field.

At the level of inspection, detection and certification, Jiangsu New Horizon Inspection, Detection and Certification Co., Ltd., a subsidiary of the Innovation Center, has established a five dimensional inspection and evaluation system for functions, ecological climate, physical performance, ecological security, and social responsibility evaluation, providing inspection, evaluation, certification, consulting and other services for chemical fiber, yarn, fabric, clothing and other enterprises.

At the level of big data model, the Innovation Center has built a secondary node based on industrial Internet identity analysis, a supply chain traceability system and blockchain technology to build a green fiber product trusted platform that can reliably trace the whole process of recycled fibers from recycling to yarn, fabric, and trade, build an industrial ecology, and provide public services such as product traceability, supply chain management, industrial finance, standard certification, and technical support. 

The convening of this forum is of great strategic significance, providing strong technical support and solutions for technological innovation and industrial development in the field of advanced fiber and new materials. It is hoped that the Innovation Center will gather innovation resources, integrate innovation carriers, speed up the research and application of green and low-carbon technologies, aim at the world's advanced level, and strengthen the research of low-carbon, zero carbon and negative carbon technologies; Strengthen the research, development and application of new fiber materials with energy conservation, emission reduction, high efficiency, low carbon and recycling, promote the improvement of key core technology breakthroughs and technology iteration capabilities, create a collaborative industrial innovation ecology, and contribute to the realization of China's dual carbon goals.

Wang Huaping, a professor of Donghua University and general manager of the National Advanced Functional Fiber Innovation Center, explained the latest development of bio based fibers with the theme of "technological innovation and industrial development trend of bio based fibers". Under the current "double carbon" development background, as the leading textile material, the green and low-carbon development of the fiber industry is crucial. this year4The Guiding Opinions on High Quality Development of Chemical Fiber Industry issued in August has formulated a panoramic picture of low-carbon development for the chemical fiber industry. Among them, bio based fiber is an important part of China's emerging strategic material field, and also an important support for building a chemical fiber power. At present, China has a complete range of bio based fiber materials,PLA、PTT、LyocellIn the following stage, chitosan, seaweed fiberPA56、PDTIt has the advantage of scale,PHBV, bacterial fiber, etc. are at the stage of international parallel run, and the benefits are generally low. Developed countries almost monopolize the high-end market in the field of large-scale bio based fiber new materials, especially with strong brand and original innovation ability and strong market influence.

Based on this situation, Wang Huaping analyzed the existing scientific problems and key technical problems of various types of bio based fibers, and proposed the future development trend: develop new technologies of biological resources, improve large-scale and efficient preparation technologies, reconstruct the new development system of the characteristics of bio based fibers, build a new generation of high-value industrial chain of bio based fibers, strengthen the product standards with the characteristics of bio based fibers, and establish green productsLCACarbon footprint assessment and bio based certification system, create a recyclable design, biodegradation and recycling technology system, refine the scenario based bio based fiber patent technology system, and deepen the integration development mode of capital, technology, product and market.

He finally mentioned that to develop engineering hard power, it is necessary to strengthen the four in one soft power, namely resource innovation, technological innovation, product innovation and service innovation.

Li Li, a professor of Hong Kong Polytechnic University, delivered a report on "Creative Economy and Interdisciplinary". She introduced that this year7In August, the Hong Kong Polytechnic University established the Institute of Fashion and Textile, which will focus on industrial design, wearable clothing, advanced manufacturing, soft materials, etc. Li Li and the team's main research direction is to use technology packaging design, that is, first study the market demand, and then select the technology30A number of enterprises have cooperated and achieved research results of a certain scale. As for how to combine creative design with traditional industries, Li Li believes that the first thing is to strengthen industrialization, the second is to deepen cooperation with traditional industries, the third is to integrate society and culture, and the fourth is to strengthen cooperation with social institutions. Next, Li Li and his team will focus on acoustic fabrics, agricultural wastes and basalt fibers, combining creative design and other disciplines for new research and development.

Lv Weibang, director of the Advanced Nanocomposite Innovation Center, delivered a report entitled "Promoting Carbon Neutralization with Nanocarbon: High Performance Nanocarbon Fiber". He believed that in the context of the current "dual carbon" development, the development of clean energy, low energy consumption and high-performance structural materials and functional materials is the key measures to reduce emissions, among which lightweight high-strength fiber composites will be the key raw materials of modern industrial equipment. Then he focused on the latest research and development of new carbon nano materials. Although the current nano carbon materials are facing challenges such as the lack of controllable equipment and engineering equipment for high-quality products, the low level of spinning theory, the insufficient application development, and the poor cooperation between production, teaching, research and application, their prospects are promising.

Professor Li Zhaoling of Donghua University gave a report entitled "Green and Efficient Extraction of Natural Cellulose Fiber". Based on the defects of the current cellulose fiber preparation methods, Li Zhaoling and his team proposed the low eutectic solvent method. This method has the advantages of simple recovery, recyclability, simple preparation process and low price, which provides a new idea for the separation of natural cellulose fibers. At present, the degumming separation mechanism, degumming effect and reuse effect of the eutectic solvent used in this method need to be further studied and confirmed.
