Column language

At present, the situation at home and abroad is undergoing profound changes and international competition is becoming increasingly fierce. On the one hand, a new round of scientific and technological revolution and industrial transformation is booming, which is changing the industrial paradigm and global industrial pattern; on the other hand, some developed countries promote the return of manufacturing industry, and the "counter globalization" undercurrent is surging. Developing countries are vigorously promoting the development of labor-intensive industries, and China's industry is facing "two-sided extrusion". Under the changing situation, there are always opportunities for change. At the new historical starting point, China's textile industry is facing new historical tasks and era topics. It needs to stand on the global level, look far ahead, and seek a new situation in the changing situation. As the mainstream media to convey the development trend of world textile technology, textile guide tries to record the development of the industry in the form of keywords, hoping that relevant practitioners can have a glimpse of the situation, think rationally, and get some inspiration. The key word in this issue is new infrastructure.

In June 2020, the national development and Reform Commission clarified the scope of "new infrastructure", and proposed the goal of "building a basic infrastructure system for industrial upgrading, integration and innovation, guided by new development concepts, driven by technological innovation, based on information network, and oriented to the needs of high-quality development". So far, the new infrastructure has a clear definition and scope. The full name of new infrastructure construction is new infrastructure construction, mainly including 5g base station construction, UHV, intercity high-speed railway and urban rail transit, new energy vehicle charging pile, big data center, artificial intelligence and industrial Internet, involving many industrial chains.

01. Textile materials help new infrastructure development

At present, innovation has occupied the core position in the overall situation of China's modernization construction, and self-reliance of science and technology is becoming the strategic support of national development. As an important application-oriented discipline, textile has the characteristics of interdisciplinary convergence and cross-border integration of multi-technology, which is an important carrier of strategic technological innovation. The innovation and development of the textile industry is reflected in the emerging effect of new technologies, new materials and new products, as well as the driving effect on new infrastructure, new equipment and new formats. It plays an irreplaceable role in improving the national innovation system and building a strong science and technology country.

High performance fibers and composites represented by carbon fiber and aramid fiber, as the key basic materials of national high-tech industry, are constantly promoting the technological progress and industrial upgrading of emerging industries such as high-speed trains, new energy vehicles and charging piles, UHV transmission lines and other emerging industries as well as new infrastructure.

In September 2018, at the Berlin International Rail Transit technology exhibition, CRRC Qingdao Sifang locomotive and rolling stock Co., Ltd. officially released the new generation of carbon fiber Metro "cetrovo". In fact, the cab, car body and equipment cabin are about 30% lighter than the raw metal materials, and the bogie is 40% lighter than the raw metal materials. So far, it is a large-scale application of carbon fiber composite on rail locomotives The model of materials. At present, cetrovo has completed the line test and operation demonstration, and passed the acceptance smoothly.

In December 2019, Datang Xilinhot power plant's 1 000 kV transmission line, the world's first "Inner Mongolia Ximeng Shandong" UHV supporting project with carbon fiber composite core conductor, has been officially connected to the grid in Inner Mongolia. The total length of the project line is 14.6km, which is erected by single circuit, and the line adopts carbon fiber composite core conductor independently developed by China. The operation of the line not only saves energy and reduces operating costs, but also increases the transmission power of 1.32 million KW · h every year, which eases the power shortage in North China.

In addition, high performance fibers and their composites can also be seen on new energy vehicles and charging piles. New energy vehicles use electricity as the driving power source, so it is necessary to consider the problems of short circuit or high voltage breakdown. Therefore, in the selection of materials, in addition to insulation voltage, corrosion protection, but also need to consider the flame retardant. Therefore, carbon fiber reinforced composites, long glass fiber flame retardant reinforced polypropylene materials, PP reinforced composites (pplgf35) have become the first choice of battery module shell.

02. New infrastructure promotes textile industry reform

The real economy with manufacturing as the core is the basis for maintaining national competitiveness and healthy economic development, which has become the consensus of all countries in the world. The scientific and technological innovation of manufacturing industry is the forefront of a new round of global scientific and technological revolution and industrial transformation.
