Can a piece of cloth be used to repair roads? Look at the textiles that open up these brains!

What do you think of lifting textiles, is it soft and elegant silk , fashionable and colorful clothing, or a comfortable and breathable home textile? Textiles not only have "small body" but also "great wisdom." With the breakthrough of science and technology, textiles play a key role as a new material in many areas such as sponge city construction, flood control and flood control, and garbage disposal. It not only promotes new economic growth points in the textile field, but also transforms and upgrades other industries. Development plays a role.

At the first Asia-Europe Geotextile Materials Conference held in Beijing recently, a series of new industrial textile technologies, materials and scientific research achievements were unveiled. Among them, many achievements have aroused the interest of foreign experts and enterprises, or will be built along the “One Belt, One Road ” project.

Aspect 1: Textiles that can “build roads”

Highways, high-speed rail construction... These "big guys" who look thick and tough are inseparable from a "cloth". Zheng Junlin, vice president of the China Industrial Textiles Industry Association, said that geotextiles made from fiber materials are embedded in the middle of the asphalt layer to achieve anti-seepage and protection, and to enhance the durability and service life of the road.

China has a vast territory and has faced many challenges in road paving, and it has a wealth of experience. For example, the construction of the Qinghai-Tibet Highway has made China a global leader in geotextiles and technology that are resistant to high temperatures, cold and dryness. Such products and technologies have attracted the attention of many foreign experts and enterprises during the forum. Zheng Junlin said that these products and technologies will go abroad and serve the infrastructure construction along the “Belt and Road”. In the future, domestic geotextile enterprises will invest in factories along the route and carry out resource allocation and capacity cooperation on a global scale.

Aspect 2: "Guards" in the construction of the sponge city

Industrial textiles can not only “build roads” but also “guards” in the construction of sponge cities.

If the city can be like a sponge, it will “water”, “water storage” and “clean water” when it rains. It needs to be “discharged” when needed. The “sponge layer” of the roof, sewer, wall and floor is very important. The geotextile and geomembrane of the sponge layer are very important. This material is also "textile".

Zheng Junlin said that relying on advanced technology, China's independent research and development of geotextiles, geomembranes, filter layers and other products can not only isolate rainwater, improve roof and surface "infiltration" ability, ensure that rainwater does not cause damage to the building structure, but also avoid fine Granular stone enters the pipeline to cause blockage.

Li Lingshen, vice president of the China National Textile and Apparel Council, said at the meeting that in 2016, the fiber processing volume of geotextiles in China increased by 9.2%, and the fiber processing volume of construction textiles increased by 14.2%. Geotextiles and construction textiles will provide a solid foundation for the construction of sponge cities.

Aspect 3: Landfill "Good Helper"

Large to repair roads and bridges, urban construction, as small as landfills, riverbank slope protection, geotextiles are everywhere. Especially in the field of landfill, high-strength, environmentally-resistant polyester filament spinning clay cloth can be called a “good helper”, which can not prevent leakage, avoid soil pollution, and disintegrate garbage. Make a difference.

The development of the industry is inseparable from the active promotion of enterprises. During the forum, the reporter learned that in the past five years, China's geotextile textile materials technology has made great progress in high efficiency, high strength and intelligence . For example, the new tunnel anti-drainage system developed and produced by Hongxiang new materials has high efficiency and can be achieved. “Drip water does not leak”; Tiandingfeng developed textile materials play an important role in water conservancy, hazardous waste landfill, high-speed rail construction, etc. Taian Luther Company intelligent geotextile with fiber optic sensors can be used for airports, bridges, highways Provides functions such as soil reinforcement, structural safety monitoring and early warning.

In the future, industrial textiles including the above will expand more application space, open up new economic growth poles, and better serve social development and people's livelihood.

The Ministry of Industry and Information Technology proposes that by 2020, the proportion of industrial textile fiber processing volume in the textile industry will increase to 33%, and the main technologies of environmental protection textiles, geotextile textiles and bio-based functional textiles will reach the world advanced level. . I believe that in the near future, there will be more "high births" of high-tech textiles, refreshing our understanding and stunning your life.
