With the increasing scarcity of natural resources, the textile and garment industry has begun to seek new alternative textile materials that are more environmentally friendly and sustainable. Adidas has announced the full use of recycled polyester fiber in 2024. H & M has also announced that 100 percent of recycled or sustainably sourced fiber materials will be used by 2030. H & M, Nike, Burberry, Gap and other brands have also joined the "circular fashion" program to reduce the global fashion industry's excessive dependence on natural resources by recycling raw materials and products. Recycling has become a fashion trend.

China is the world's largest producer and consumer of chemical fiber, with large reserves of waste products, but the regeneration rate is less than 10%. Polyester fiber is the leading product of chemical fiber. At present, most of the waste polyester and its products are treated as landfill or incineration, and its recycling is the key to the sustainable development of textile and chemical fiber industry.

The development of recycling is the requirement of changing the mode of economic development and the only way to improve the efficiency of resource utilization. In order to further implement the national innovation driven development strategy, implement the outline of building a strong textile country (2011-2020), promote the development of recycling textile processing in the whole industry to the breadth and depth, and realize the recycling of resources in a larger scope and higher efficiency, from April 3 to 4, sponsored by the Textile Light Science and Technology Education Foundation, the Science and Technology Development Department of China Textile Industry Federation, and the Textile Industry Science and Technology Development Center, the "Textile Light" recycling textile processing key technologies and applied scientific and technological achievements promotion activities were held in Ningbo, Zhejiang Province.

    High-end interviews: clear development direction and path

In April last year, the Chinese Academy of Engineering released the results of the project "Research on the Development Strategy of Recycling Technology of waste Chemical Fiber Textile Resources", which studied the current situation and development trend of recycling of waste textile resources at home and abroad. this paper analyzes the bottleneck, development characteristics and solutions of the recycling development of waste chemical fiber textile resources in China, and on this basis puts forward the key tasks, major special suggestions and development policies and measures. In this regard, Sun Jinliang said in a high-end interview that the recycling of waste textiles is a major problem for the whole society. Although a lot of work has been done at present, the change of people's concept, the recycling of enterprise waste, and the recycling of uniforms of troops, factories and mines should arouse enough attention from the society. In addition, it is necessary to strengthen publicity, mobilize the strength of the whole society, and work together to realize the recycling of waste textile resources.

Yu Jianyong believes that recycling determines the sustainable development of the industry, which is not only the concept of manufacturing, but also the terminal market. International brands have their own special plans, and the real consumption wave is forming, which also brings urgency to the growth of the industry. The key to the textile recycling industry is to realize the transformation of manufacturing mode, from linear development to circular development, and finally form the textile cycle and establish a new circular production mode. The key to realizing the cycle is to focus on the key points, in line with the characteristics of the raw material structure, first polyester, then nylon, and then other niche fibers. The path to achieve circulation should consider maximizing energy efficiency, and different raw materials should be treated in different ways. Facing the special engineering problem of regeneration, we should study the most economical processing method, take the product quality as the core, and deal with the waste in the processing process. In addition, processing should keep up with the changes in the market and allow the entire industrial chain to circulate.

He Yanli said that the amount of waste textiles is very large, and high value-added applications should be considered. But there is no second-hand clothing market, recycling channels, sorting standards are not sound, national policies and regulations have not formed a system. At present, more than 90% of bottle slices can be recycled, but the recycling of waste textiles is still far from complete. Therefore, the China Chemical Fiber Industry Association will promote the directional recycling of waste textiles as a breakthrough to promote the recycling of waste textiles. In addition, it is necessary to increase publicity to let everyone understand that the recycling of waste textiles can still be of high quality. Only when consumers recognize it can the industry continue to develop. She also hopes that more responsible companies will obtain green fiber certification, survival of the fittest, and let good companies stand out.

Hao Xinmin, a senior engineer at the Institute of Quartermaster Engineering and Technology of the Institute of Systems Engineering of the Academy of military Sciences, said that a large number of 07 military uniforms have been recycled, and the current treatment plan has been formed. The new era of military uniforms has been from the source, through the use of new materials, to consider the issue of recycling. In the future, we should strengthen the research on soft topics to facilitate the recycling and classification of clothing, home textiles and other categories, and make the recycling of waste textiles operate well through standards.

Huanjia Group is the largest bottle recycling enterprise in China. Zhu Hongjun, deputy general manager of the company, introduced the recycling system, which is of great reference to the textile recycling cycle.

Zhang Deliang, vice president of Shanghai Textile Science Research Institute, introduced the progress of standard research from the perspective of regenerated fiber identification and safety.

Another high-end interview focused on production applications and experience sharing, wu Anfu, Manager of Innovation and Research Department of Li Ning (China) Sporting Goods Co., Ltd., Lu, Marketing Manager of Shanghai Shenyang Teng Auto Textile Interior Co., Ltd., Cui Zhanming, Chairman of Hongxiang New Materials Co., Ltd., Dong Qinxia, Chief Engineer of Ningbo Shenzhou Knitting Co., Ltd., Bao Yuan, Project Manager of Shanghai Youke Machinery Technology Co., Ltd., Qian Jun, Director of Textile Industry Recycled Polyester Technology Innovation Center, from the brand, knitting production, industrial use, equipment, renewable fiber innovation and other angles of upstream and downstream interaction. We hope that the terminal brand, recycled fiber production enterprises and application enterprises will join hands to contribute to the recycling of waste textiles.

In the high-end interview session, the interaction between the stage and the stage made every participant feel benefited.
