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，我国纺织行业在未来发展时应当注重4方面建设：一是实现多功能、多性能化学纤维以及生物基纤维的发展，我国高性能纤维产量不是最高，但应用范围和产品种类很广，且市场需求呈现不断上升的趋势，安全防护用纺织品发展更是离不开高性能纤维技术的支撑；二是高端产业用纺织品，发达国家对纺织强国的基本定义是产业用纺织品占比达到1/3以上，2018年我国产业用纺织品纤维加工总量达到1560万吨，占整个纤维加工总量的28.5%，从国内行业市场发展情况来看，产业用纺织品日益增长和发展空间很大，应急与公共安全、国防与军工等领域的发展为安全防护用纺织品带来了更多、更好的发展机遇；三是智能制造，未来企业的竞争是数字资产价值的竞争，企业应当积极关注数字化建设，网络化建设，只有实现各个生产系统的互联互通，才能实现自身核心竞 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. 据蒋士成介绍，高性能纤维技术发展方向主要体现在4个方面，一是产品高性能化、专业化、结构功能一体化，围绕汽车、高铁、海洋工程、环保等重大应用领域需求，设计研发高强高模、防裂、耐高温、使用寿命长和高可靠等新型专业化、系列化高性能纤维品种；二是加工技术高效稳定化，重点关注单体高效合成与提纯、高转化率聚合及其稳定化控制、高浓度纺丝原液的高效连续制备与低降解、高粘度纺丝溶液的快速脱泡与高均质化等技术；三是加工体系智能化，发展生产流程的信息化、智能化及产品的可追溯性，推广智能工厂、智能车间示范应用，提高高性能纤维生产效率与产品品质，降低生产成本，扩大市场应用；四是原料体系专业化配套定制，碳纤维、高强高模聚乙烯、聚酰亚胺纤维等生产的单体、溶剂、上浆剂等实现专业化标准化定制，开发与高性能纤 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.
