Textiles show new business cards: technology is the best footnote for changing lives

In recent years, industrial textiles industry very well carry a new level of growth in the important task of the textile industry, industrial textiles industry has not only become an important direction and the main way the textile industry transformation and upgrading and structural adjustment, has become a national strategic emerging industries The components and diversified high-tech industries across multiple sectors.

We have seen that the industrial textile industry has made important contributions to meeting people's living needs, protecting the natural ecological environment, improving the quality of infrastructure, driving the development of related industries, strengthening China's national defense strength and overall national strength.

Rapid advancement in technological innovation

Industrial textiles industry as the key fields of textile science and technology innovation is an important direction of the textile industry structure adjustment and upgrading, but also focus on the developed countries striving to develop. 11 innovation agency of the US National Manufacturing Innovation Network program has been established, in which advanced composite materials and the revolutionary fiber and fabric manufacturing both institutions related to textiles.

At the same time, the industrial textile industry is also an area with broad application potential across industries. Industrial textiles are widely used in many fields such as medical health, environmental protection, safety protection, construction transportation, aerospace and many other fields. Because of their flexibility, they are highly processable and have a huge space to replace traditional materials. The industrial textile industry has not only emerged a number of national science and technology progress awards and industry science and technology progress awards projects, but also a lot of innovations in various sub-fields of industrial textiles, forming a situation of innovation.

In the field of structural reinforcement textiles, the semi-rigid battery windsurfing warp knitting material has greatly reduced the weight of the “Tiangong No.1” satellite; the glass fiber and carbon fiber composite materials have reduced the weight of the wind turbine blade and prolonged its service life; large-diameter high-pressure soft body transmission, storage tanks have been used in the defense industry tube and emergency rescue; large aircraft to achieve mass production of carbon fiber composite material structural member; carbon fiber composite core wire is widely used in power transmission lines.

In the field of other industrial textiles, the promotion of warblized sand barriers and desert vegetation restoration technology has achieved initial results; the localization of dewatering equipment such as high-speed paper-making carpets has reduced the production costs of downstream enterprises; biomass spinning and non-woven sand-fixing materials to improve the effect of desert control and avoid secondary pollution; industrial CNC cutting and connecting equipment and technology progress, a substantial increase in the industrial production of intelligent textile articles.

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.

No doubt, with the enhancement of eco-environmental awareness, healthy development of the pension industry, new industries and growing "along the way" strategic propulsion, industrial textiles have a larger space for development. "Thirteen Five" period, fiber-based composite materials and other new materials, industrial textiles, textiles air pollution control, water treatment and pollution control textiles, soil pollution control textiles, medical textiles textiles, health care intelligence, rehabilitation care textiles, prevent and respond to natural disasters, textiles, prevention and emergency handling production safety accidents textiles, deal with public safety and health events supporting textiles textiles, international and domestic construction of key projects, "along the way" along the transfer of industries supporting the use of 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.

For the future development goals of the industrial textile industry, the industry will maintain rapid and steady growth during the “13th Five-Year Plan” period. The industrial added value of enterprises above designated size will increase by 9% annually, and the total fiber processing industry will grow by more than 8% annually. The proportion of industrial fiber processing will reach 33%; the capacity for independent innovation will be significantly improved. The proportion of R&D investment in 100 key enterprises will increase from 1.9% in 2015 to 2.5% in 2020; textiles and geotechnical materials for environmental protection The main technologies of construction textiles and bio-based functional textiles will reach the world's advanced level; the industrial structure will be further optimized, the quality and efficiency will be significantly improved, and the sustainable development capability will be enhanced, and a group of industrial textile enterprises with international influence will be cultivated.

The industrial textile industry has entered a relatively stable growth period. In this process, the growth rate and the transformation and upgrading coexist. Both the relatively high speed is growing and the technological advanced stage is coming. Two characteristics will appear. Looking forward to the industry's innovation and development, creating markets, exploring different attributes and end uses of products is a very important development direction of the industry. The industrial textile industry should be “widely applied and infinitely replaced”, constantly welcoming new fields and new competitors, and the largest competitive advantage will come from your ability with customers, suppliers to develop new products together.
