Professional Protection: Safety And Protection Textiles, Industry, University And Research Cooperation Forum

In November 1st, a forum on textile industry university research cooperation for safety and protection was held in Nantong, Jiangsu. Nearly 200 participants in the industry participated.

The conference is sponsored by China Industrial Textiles Association, and is hosted by Nantong University, Nantong science and Technology Association and Nantong high end textile industry association.

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 terms of research and development of textiles for safety protection, the national science and technology innovation platform for research and development, the National Joint Research Center for research and development of special fiber composite materials for safety protection, focuses on 6 aspects: nuclear and biochemical protection, high-performance fiber composite materials, radiation protection high-performance fiber composite materials, bullet proof and mechanical damage resistant high-performance fiber composites, thermal protection high performance fiber composite materials, medical protective high-performance fiber composites and wearable intelligent high-performance fiber composite materials. The whole chain innovative design is carried out from basic research, applied research, product development, achievement transformation and industrialization to solve 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 technological innovation platform system have been constructed. The overall competitiveness of China's 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 short boards and relatively high end products.

　　他表示，我國紡織行業在未來發展時應當注重4方面建設：一是實現多功能、多性能化學纖維以及生物基纖維的發展，我國高性能纖維產量不是最高，但應用范圍和產品種類很廣，且市場需求呈現不斷上升的趨勢，安全防護用紡織品發展更是離不開高性能纖維技術的支撐；二是高端產業用紡織品，發達國家對紡織強國的基本定義是產業用紡織品占比達到1/3以上，2018年我國產業用紡織品纖維加工總量達到1560萬噸，占整個纖維加工總量的28.5%，從國內行業市場發展情況來看，產業用紡織品日益增長和發展空間很大，應急與公共安全、國防與軍工等領域的發展為安全防護用紡織品帶來了更多、更好的發展機遇；三是智能制造，未來企業的競爭是數字資產價值的競爭，企業應當積極關注數字化建設，網絡化建設，只有實現各個生產系統的互聯互通，才能實現自身核心競 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. 據蔣士成介紹，高性能纖維技術發展方向主要體現在4個方面，一是產品高性能化、專業化、結構功能一體化，圍繞汽車、高鐵、海洋工程、環保等重大應用領域需求，設計研發高強高模、防裂、耐高溫、使用壽命長和高可靠等新型專業化、系列化高性能纖維品種；二是加工技術高效穩定化，重點關注單體高效合成與提純、高轉化率聚合及其穩定化控制、高濃度紡絲原液的高效連續制備與低降解、高粘度紡絲溶液的快速脫泡與高均質化等技術；三是加工體系智能化，發展生產流程的信息化、智能化及產品的可追溯性，推廣智能工廠、智能車間示范應用，提高高性能纖維生產效率與產品品質，降低生產成本，擴大市場應用；四是原料體系專業化配套定制，碳纖維、高強高模聚乙烯、聚酰亞胺纖維等生產的單體、溶劑、上漿劑等實現專業化標準化定制，開發與高性能纖 The matching of spinning agent, sizing agent and fiber characterization technology can 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.
