　　 Research on industrial chain

　　 Fu Shaohai, Dean of the school of textile and clothing of Jiangnan University, discusses the problems of insufficient coloring rate and easy to expose in spandex dyeing. The dyeing process, dyeing mechanism and development direction of spandex dyeing are mainly analyzed. For how to improve the dyeing properties of spandex, Fu Shaohai gives two feasible plans: one is to adjust the dyeing process - adding dyeing auxiliaries or using special dyes for spandex. The second is to modify spandex, such as redesign the molecular structure of spandex; Or innovative spinning technology, such as adding substances that can increase the "dye seat" of spandex during the spinning process, so as to improve the dyeing performance, or through the design of composite yarn, core-shell structure yarn can be constructed, such as polyurethane loaded with CNT as the core layer and cotton fiber as the shell layer; Or surface modification of polyurethane, such as hydrophilic modification, oxidation in strong acid solution or plasma treatment, immersion in crosslinking agent, and grafting with hydrophilic compounds can significantly improve the surface hydrophilicity of polyurethane, thus improving its dyeing performance.

　　 Zhang duoyao, general manager of Changlian chemical (Panjin) Co., Ltd., introduced the company's products methanol derivatives, ethylene derivatives, propylene derivatives and their supply chain, and shared 1,4-butanediol (BDO) and polytetramethylene ether glycol (PTMEG) He pointed out that as the main downstream of BDO, PTG has become an important support for BDO elimination while maintaining stability in the PTG spandex industry chain. As the largest part of BDO downstream export, PBT industry has a direct impact on BDO. With the rapid development of new energy, GBL / NMP has a good application prospect in lithium battery electrolyte industry The demand for spandex is supported by the upstream supply shortage, and the PTMEG market will rise sharply in 2021. The downstream spandex manufacturers are about to expand their production, such as Xinxiang Chemical fiber, Huafeng spandex, Xiaoxing spandex, Zhuji Huahai and other spandex manufacturers. It is expected that the subsequent supply will be tight.

　　 The development of functional spandex is the key to upgrade the industrial structure and enhance the competitiveness of the industry. Wei Peng, associate professor of Textile College of Zhongyuan Institute of technology, shared the research on the preparation and properties of functional high temperature resistant and elastic controllable spandex, and introduced the development, preparation ideas and downstream application of functional spandex such as antibacterial, graphene modified, chlorine resistant and flame retardant. He pointed out that there are four main types of spandex, including bare silk, core spun yarn, twisted yarn and covered yarn, which account for the largest proportion in textile, clothing and home textiles, accounting for more than 80% of the overall demand; The proportion of health care products increased year by year, and the consumption was about 15%. Among them, medical supplies accounted for 52%, which were mainly used for masks, protective clothing, isolation clothing, operating clothes, surgical caps, bandages, protective bands, band aid, dressing base cloth, etc., and health care products accounted for 48%, mainly used for diapers, sanitary napkins, wrist guards, knee pads, pressure socks, etc.

　　 Wei Peng said that lightweight and comfortable textiles and medical and health products are still the main application areas of spandex, and the market demand is strong. Therefore, under the premise of ensuring the excellent elasticity of superfine spandex, more attention should be paid to the development of high heat resistance, easy dyeing spandex, new biodegradable spandex, elastic controllable spandex and spandex for intelligent textiles.

　　 Brand application

　　 Medical and health textiles are one kind of industrial textiles, which are mainly used in medical treatment, medical protection, public health, personal health, nursing care and other fields. The common products include protective clothing, operating clothes, isolation clothes, masks, diapers, wipes, etc. Professor Feng Yan of Tianjin University of technology, who came out of the courtyard of Xinxiang Chemical fiber family area, made a report on the development and application of medical textiles. She introduced in detail the structure, performance requirements, production methods, application and development trend of medical and health textiles such as masks, protective clothing and wipes.

　　 Yang Jie, deputy general manager of Xiamen seven wolf Knitting Co., Ltd., through the data research on the spandex industry, combined with the development status of the clothing industry, the use of spandex in the clothing industry and the future development situation of the industry were prospected. Yang Jie said that because consumers' bodies are unique and the size alone is not enough to represent the body shape, the traditional size of clothing may not be suitable for every consumer in the size, which increases the use of spandex. He pointed out that at present, consumers put forward more requirements for the comfort and functionality of clothing products, and correspondingly higher requirements for high elasticity of spandex. They hope to have spandex with conductive, super flexible and color. Differentiation and differentiation are one of the development directions of spandex.

　　 Dong Yi, R & D director of Hunan Sari socks Co., Ltd., summarized the key technology and the best performance of spandex in the application of functional socks based on the actual cases of spandex in different functional socks. At the same time, the development trend of spandex in the future is proposed.
