Into the mid-to-high end to continue to expand applications and alternatives

Complying with the new round of scientific and technological revolution and industrial transformation trends, accelerating the construction of modern industrial technology system is one of the themes of China's current economic restructuring. Scientific and technological innovation is an important engine for the development of industrial textile industry. The multi-disciplinary and multi-field cross-integration reflects the characteristics of the industry and the direction of innovation. We have seen that the main field of high-performance fiber applications is industrial textiles. It can be said that improving the level of innovation in industrial textiles is the main task for China's textile industry to create new competitive advantages and move towards the mid-to-high end. In recent years, the growth rate of global industrial textile fiber processing volume is about twice that of all textile fiber processing. According to the prediction of relevant UN agencies, by 2050, 68% of the world's textile fibers will be used for industrial textiles.

The “Thirteenth Five-Year” development plan for the industrial textile industry first proposed six major national key development strategy supporting projects, embedding industry development into the consideration of national strategic development. These six areas are: strategic emerging industry supporting projects, environmental protection supporting projects, health and pension industry supporting projects, emergency and public safety industry supporting projects, “One Belt and One Road” strategic supporting projects, and “military and civilian integration” supporting projects.

Undoubtedly, with the improvement of eco-environmental awareness, the development of healthy pension industry, the growing of emerging industries and the promotion of the “One Belt, One Road” strategy, industrial textiles have a large space for development. During the “Thirteenth Five-Year Plan” period, fiber-based composite materials and other new materials for industrial textiles, air pollution control textiles, water treatment and pollution control textiles, soil pollution control textiles, medical and health textiles, health care and intelligent textiles, Rehabilitation and care textiles, textiles for prevention and response to natural disasters, textiles for the prevention and emergency disposal of textiles for safety accidents, textiles for public safety and health incidents, textiles for international and domestic key projects, and industrial transfer for the “Belt and Road” Textiles, as well as “military and civilian integration” and other “military and civilian integration” related industrial textiles will become the key development direction.

It should be pointed out that in the future, with the continuous advancement of high-performance fiber and bio-based fiber technology, and its integration with nano, information, three-dimensional molding and other technologies, coupled with textile-based functional materials and multifunctional composite processing technology and application. The improvement of the level and the continuous improvement of the simulation comprehensive evaluation system will raise the technical level of the industry to a new level. With the upgrading of equipment, technology and technology, and the popularization and application of industrial robots, Internet of Things, big data systems, and the introduction of intelligent, differentiated and personalized manufacturing models, the performance level of industrial textiles and the substitution in related fields The proportion will continue to increase and expand more new application space and market share.
