Xu Xinmin, vice mayor of Nantong Municipal People's government, said in his speech that the high-end textile industry is one of the three major pillar industries in Nantong's "13th Five-Year" development. Nantong textile industry has a good foundation, forming a chain of chemical fiber, textile, printing and dyeing and finishing, clothing and home textiles. In 2018, the city's high-end textile industry achieved an output value of 220 billion 800 million yuan, an increase of 9.8% over the same period last year, and the main business revenue output value was 218 billion 800 million yuan, an increase of 9.8% over the same period last year, with a profit of 17 billion 100 million yuan, an increase of 15.5% over the same period last year. The textile industry in the city has 30 engineering and technology centers at the provincial level or above, 3 provincial academician workstations, and 20 well-known trademarks in China. The safety protection industry has important social significance and industry value. The Nantong municipal government will vigorously support and provide more convenience for the development of enterprises.

Shi Weidong, President of Nantong University, introduced the current research system of Nantong University at his address. He said that the textile School of Nantong University has six undergraduate majors, including textile engineering, light chemical engineering, nonwoven materials and engineering, fashion design and engineering, clothing and costume design and performance. In the field of research and development of textiles for safety protection, the national science and technology innovation platform for research and development, the National Joint Engineering Research Center for the development of special fiber composites for safety protection, focuses on the protection of high-performance fiber composites, radiation protection and high-performance fiber composites, bulletproof and mechanical damage, high-performance fiber composites, thermal protection and high-performance fiber composites. Materials, medical protective high-performance fiber composites and wearable smart high-performance fiber composites have been studied in 6 aspects, including basic research, application research, product development, achievements transformation and industrialization, etc., to solve the major common technical problems in the development of textile, emergency protection and other related industries.

Li Lingshen, vice president of China Federation of textile industry and President of China Industrial Textiles Association, said that in recent years, China's textile industry has achieved rapid development in science and technology, running from running to running, and running to some fields. A large number of scientific and technological achievements have been certified by the state, and a complete production system, industrial chain system and scientific and technological innovation platform system have been established. The competitiveness of the textile industry has been significantly improved, but at the same time, we should also realize that in the global textile industry chain, China's textile industry still has a short board, and high-end products are relatively few.

He said that China's textile industry should focus on 4 aspects in the future development: first, the development of multi-functional, multi-functional chemical fibers and bio based fibers. The production of high performance fibers in China is not the highest, but the range of applications and products are very wide, and the market demand is rising. The development of safety protection textiles is inseparable from high-performance fiber technology. Support; The two is the high-end industrial textiles. The basic definition of developed countries to textile power is that industrial textiles account for more than 1/3. In 2018, the total amount of industrial textile fiber processing in China reached 15 million 600 thousand tons, accounting for 28.5% of the total fiber processing. According to the development of domestic industry market, the growth and development space of industrial textiles were very large. The development of defense and military industry has brought more and better opportunities for development of textiles for safety protection. The three is intelligent manufacturing. In the future, the competition among enterprises is the competition of digital assets value. Enterprises should pay close attention to the construction of digitalization and networking. Only by realizing the interconnection and interconnection of all production systems can enterprises realize their core competitiveness. The four is green manufacturing. To achieve green manufacturing, we must pay attention to the research and development of green fibers, and realize the green of textile production in order to achieve the closed-loop green of textile production. The competent enterprises should try to study the high quality and quantitative development of recycled materials, strengthen the combination of basic research and industrial application, and help the industry achieve healthy transformation.

Jiang Shicheng, academician of the Chinese Academy of engineering, made a keynote speech entitled "the development status and the direction of technology development of high-performance fibers for composite materials for safety protection". He said that at present, the development of high performance fibers in China has shown a good momentum of development. The support of industrial policies has increased, the level of technology has been continuously improved, and the market demand has continued to grow. All these have provided impetus for the development of high performance fibers in China. According to Jiang Shicheng, the development direction of high performance fiber technology is mainly reflected in 4 aspects: first, the high performance, specialization and structural function integration of the products. Around the needs of major applications such as automobile, high-speed rail, marine engineering, environmental protection, etc., we design and develop new specialized, serialized and high-performance fiber varieties with high strength, high modulus, crack resistance, high temperature resistance, long service life and high reliability. Two, the processing technology is highly efficient and stable. It focuses on the efficient synthesis and purification of monomer, high conversion polymerization and stabilization control, high efficient continuous preparation of high concentration spinning solution, low degradation, rapid defoaming and high homogenization technology of high viscosity spinning solution. Three is the intellectualization of the processing system, the development of the production process information, intelligence and product traceability, the promotion of intelligent factory, intelligent workshop demonstration application, improve the production efficiency and product quality of high-performance fiber, reduce production costs, expand market applications; The four is the specialized customization of the raw material system. Specialized monomers, solvents, sizing agents, such as carbon fiber, high strength high modulus polyethylene, polyimide fiber and so on, are professionally standardized and customized. The spinning agent, sizing agent and fiber evaluation characterization technology, which are compatible with high-performance fibers, are developed to enhance the applicability of products and achieve large-scale production.

Two experts from military research institutes introduced the development trend of bulletproof vest, bulletproof helmets and anti biochemical personal protective equipment.

Zhao Xiaoming, Professor of Tianjin University of Technology, made a keynote speech entitled "analysis of the development direction of electromagnetic wave absorbing materials technology". He said that the absorbing material is a kind of material that can absorb and attenuate the incident electromagnetic wave, and transform its electromagnetic energy into other forms of energy diffusion, or cause electromagnetic wave interference to disappear. As far as the current development of absorbing materials is concerned, single materials are difficult to meet the increasing requirements of "thin, light, wide and strong". Therefore, different materials need to be combined in various forms to achieve more effective and adjust the electromagnetic parameters of the composites to the greatest extent.

In the afternoon session, Professor Zhang Qinghua of Donghua University introduced the properties of polyamide Fitlon dyeable polyimide fiber and its application in the field of safety protection. Fitlon fiber has low thermal conductivity, good flame retardancy, excellent UV resistance and heat oxidation resistance. It can be used in professional field protection, such as forest fire prevention clothing, fire fighting clothing, and chemical, metallurgical, thermal power generation, geological, mining and nuclear industry and other professional protection.

Yuan Guoqiu, Professor of Nantong University, associate professor Liu Qixia, Long Xiaoyun, Cao Haijian and Yan Xuefeng respectively introduced the development and application of Shi Moji heterostructure materials, high-performance bioprotective materials, carbon / magnetic composite flexible wave absorbing nonwoven materials, bulletproof and mechanical damage textiles, cutting injury protective textile materials. These topics rely on the research and development of the national special local fiber joint Engineering Research Center for safety protection, and have made landmark achievements, and have been affirmed by participating enterprises.

During the same period, the seminar on the production and research achievements of the textile and Garment College of Nantong University was held, as well as the preparatory work conference for the technical innovation alliance of textile composites industry for safety and protection. Some guests visited the national joint local engineering research center for the development of special fiber composites for safety protection.
