Shock! These "black technologies" actually come from textile mills.

On December 18th, the highest technology award in China's textile industry, the "Textile Light" Science and Technology Education Award was presented. Don't underestimate this 14-year-old award! It is not only the cradle of the National Science and Technology Progress Award, but many black technologies that shocked the world were born in the Chinese textile mills that won the award. Today, Spicy Sister gives you an award-winning black technology that affects your life!

Metal mesh, the second country in the world that can develop and transmit satellite antennas with a diameter of more than 10 meters.

Is the textile factory related to satellite creation? Absolutely! The first star of China's satellite mobile communication system - Tiantong No. 1 01 star, has the high technology born in our textile industry!

There is a special umbrella in the laboratory of Donghua University. This umbrella is neither rain nor shade, because its umbrella is not ordinary nylon, but an ultra-thin metal mesh. It is this metal network that has shown great power in many satellites such as China's Beidou navigation satellites and mobile communication satellites. It has broken the history of long-term dependence on imports of satellite metal network antennas in China.

The metal mesh is the key component of the satellite antenna to reflect electromagnetic waves and the basic material of the spaceborne mesh antenna. However, it is well known that "to the easy to fold", the extremely thin wire has high rigidity, small elongation, large residual torque, and the metal becomes a uniform and soft "cloth", and the difficulty is conceivable. Donghua University, which has long been concentrating on textile technology, cooperated with Xi'an Space Radio Technology Research Institute, Wuyang Textile Machinery, Jiangsu Runyuan and other enterprises to achieve only 1/4 of the hair with the fine wire and the warp knitting technology. The coarse and extremely fine gold-plated molybdenum wire fiber is twisted and twisted, and the innovative design and manufacture of special doubling, warping and warp knitting equipment and complete production process.

This series of technical and technological breakthroughs has achieved the “rigid and flexible” of the satellite antenna metal mesh, and also reduced the metal mesh by more than 90%, making it easier to carry and size. This set of "key technology for the production of very fine wire warp knitting and its application on large expandable flexible spaceborne antennas" also won the first prize of this year's "Textile Light" technology category.

"The results have independent intellectual property rights , and the overall technology has reached the international leading level. The metal mesh products developed by the project have been successfully applied in China's high-performance satellites, greatly improving the communication capabilities of China's satellites and breaking the monopoly of foreign technology. And make China the second country in the world that can develop and transmit satellite-borne antennas with a diameter of more than 10 meters after the United States." Li Lingshen, vice president of the China National Textile and Apparel Council, said, "Advanced technology has improved the application of textiles. And added value. The research and development of new technologies, new processes and new equipment has greatly enhanced the added value of textiles and expanded the field of textile applications."

Swallowing bottle, old film, spit new Blanket, car board

Are Coke bottles and old film related to cars? As long as there is black technology for the recycling of used polyester fibers, they are inseparable.

According to reports, China produces about 21 million tons of waste textiles every year in the production and consumption sectors, and the utilization rate is less than 14%. If cotton and linen textiles in China's waste textiles can be fully recycled, the annual supply of natural fiber is about 6 million tons, which exceeds the annual output of cotton in the country, which is equivalent to reducing the occupation of 20 million mu of cultivated land, which can greatly alleviate the bottleneck of raw materials in the textile industry. And if it can greatly increase the recycling rate of chemical fiber products, it will save millions of tons of crude oil per year for China.

However, recycling can be a test of real effort. Due to the complicated source of waste raw materials, the difference in color, purity and viscosity, and the large amount of impurities, every step in the production of sorting, cleaning and melt spinning is a problem. Through efficient and flexible processing, Zhejiang Luyu Environmental Protection Co., Ltd. and Ningbo Dafa Chemical Fiber Co., Ltd. have realized the recycling of waste fibers with high quality and high value, and constructed a waste polyester fiber regeneration system with complete intellectual property rights. Using the waste polyester bottle flakes to produce the key technology and industrialization of recycled polyester BCF puffed filaments, Longfu Huaneng can swallow 2.6 billion used plastic bottles every year and spit out 6 million environmentally friendly blankets. These companies have won this year's textile technology award.

According to Li Lingshen, China has built the world's largest production base of recycled polyester fiber with polyester waste fiber as raw material. The products have been widely used in construction materials, automotive sheet and other fields, and the overall technology has reached the international advanced level. Efficient recycling of waste polyester fiber products and high value-added development.

"Technology, fashion, green" will become a new label for China's textile industry

In addition to these high-quality textile technologies, there are still many textile innovations in 2017. By improving the quality of apparel fabrics , the Chinese people's clothing experience has been greatly improved.

Is there a bad experience of sweating in a down jacket? Jiangsu Danmao has innovated a down jacket fabric with humidity control and temperature control. The fabric made of functional polyester and wool fiber blending fabric can accelerate the evaporation of moisture on the surface of the fiber by using body heat, and store heat and heat. After the fabric is compounded with high moisture permeable and breathable film, it also has good anti-drilling and windproof and rainproof functions, so that the wearer is always in constant temperature and humidity of 37.5 degrees.

Have you ever had a splash on your chest when you have a shirt on your chest? Have you ever tried to clean the neckline stains? This year, Lutai Textile launched an easy-to-care shirt using high-tech means. This shirt has a functional partition design. In addition to the overall anti-wrinkle, the dirty collar and cuffs are also waterproof, oil-proof and anti-fouling, especially easy to decontaminate; the front of the shirt that is easily stained has nanometer three Anti-staining and anti-staining function; the sweat-prone back sheet and sleeve have the function of moisture absorption and quick drying, which greatly reduces the difficulty of garment care and saves water.

Finally, friends who love outdoor sports are also blessed. In the past, China's anti-UV clothing, light and beautiful, poor functionality, easy to tan; true sunscreen is too heavy and too stuffy, how to be both functional and aesthetic? Pathfinder obtained the ultra-thin UV-resistant multi-functional fabric of Textile Technology Award this year, imitating the scale structure of the sunset butterfly, adding only 3 grams of coating per square meter, forming a moisture-permeable, breathable, waterproof, UV-blocking Light and thin shield.

Sun Ruizhe, president of the China National Textile and Apparel Council, said that in the new historical period, it is necessary to accelerate the construction of textile and technological powers, brand powers, sustainable development powers and textile talents . "In a long period of time in the future, China Textile will focus on technological innovation and product development, and shape the new positioning of China's textile industry, that is, to create the industry as an innovation-driven technology industry, a culture-led fashion industry and a responsible-oriented green industry. , 'Technology, fashion, green' will become a new label for the textile industry."
