Gu Ping said that China's textile industry has developed rapidly, with obvious advantages in scale and manufacturing, but is also faced with multiple constraints such as employment, environment, raw materials and so on. In addition, Sino US trade friction has led to a re layout of the international trade pattern, leading China's leading industrial chain nodes to foreign countries, which has weakened the comprehensive international competitive advantage of China's textile industry. Therefore, industrial upgrading and high quality development are particularly urgent. Through the preliminary statistics on the import and export volume of China's textile machinery industry and the production and sales in the first three quarters of the key enterprises in the 1~9 months of this year, and the development of ITMA2019 nonwoven equipment, Gu Ping analyzed that the market demand of Nonwovens Materials is still strong in the next five years, and the development trend of nonwoven equipment is high speed and high yield, circular economy and digital automation. For the trend of textile intelligent manufacturing, Gu Ping put forward three suggestions: first, to strengthen the development of automation, digitization and intellectualization of textile equipment; two, to promote the construction of textile intelligent factories (workshop); three, to make up the standard framework of Intelligent Manufacturing in textile field.
Liu Yaozhong, director of the textile industry branch of China Council for the promotion of trade (CCPIT), combined with the trade war between China and the US. He said that the textile industry is facing the common challenges of the lack of healthy and sustainable development of the global economy, the severe challenges of economic globalization and trade liberalization, the need for deep digital transformation at the supply side and the consumer side, and the continuous upgrading of automation and intelligent manufacturing to bring new challenges to the industrialization of the late-onset countries. Liu Yaozhong analyzed the Sino US economic and trade frictions and tariffs, the 13 rounds of Sino US economic and trade consultations, the measures adopted by the Chinese government, and the nature and trend of Sino US economic and trade frictions. He believes that from the perspective of the international layout and progress of China's textile industry, "one belt and one road" has created good opportunities for the development of China's textile industry international cooperation. With regard to the two main lines of the transnational layout of productive forces and the global cooperation of high-quality resources, the transnational regional cooperation of textile industrial chain, supply chain and value chain will accelerate. In the future, China will expand its opening up to the world, especially opening up huge domestic markets, co - operation, co - construction and sharing, so as to achieve win-win cooperation and sustainable development.
Professor Qian Xiaoming of Tianjin University of Technology mainly introduced the present situation and trend of needle punched nonwovens. He said that acupuncture technology can be combined with different processes, different nets and different raw materials to produce high performance and versatile products, further enhance the application field and added value of needled nonwoven products, and acupuncture compound products are the development direction of acupuncture technology in the future, and promote the development of the entire nonwoven industry. Nowadays, needle punched products have been widely used in filtration, geotextile, leather and wiping, etc. the process of filtering nonwovens has been realized by many technologies such as spunbond, carding, needling, spunlace, laminating, finishing and so on. A new type of filtering material has been developed in the direction of microfiber, density gradient and structural design.
