CCTV'S Large-Scale Industrial Documentary Focuses On The Development Of New Textile Materials

Since the chemical industry

Human beings play the role of creation

Just one century

Created countless new species of materials

Our life has been closely related to them

Cannot be separated for a moment

CCTV Finance Program Center Large scale industrial documentary "The Backbone" Focusing on materials, the sharp weapon of big country competition, the magic weapon of enterprise competition, and the support of a better life, and gathering the wisdom and painstaking efforts of nearly 20 top material scientists and academicians, we conducted an in-depth visit, three-dimensional presentation, and comprehensive display of the material industry system supporting the high-quality development of Made in China for the first time from a panoramic perspective and an epic pattern.

　　 The large-scale industrial documentary "A pillar of a pillar" will be broadcast on CCTV Finance Channel at 19:43 every day from July 17 to 20, and from July 24 to 25. On July 19, the third episode of Legend of Creation was broadcast.

　　 0.05 denier microfiber! The Chinese have broken their own world record again!

Remember the silk stockings that swept the world in the last century? It uses nylon, the first synthetic fiber in the world. After that, more and more chemical fibers were invented.

Someone once asserted that without chemical fiber, cotton would be hard to solve the clothing problem of people all over the world.

How did crude oil become a chemical fiber? Tap the video to see the legend of the chemical industry from oil to silk ↓

It was once speculated that as long as the chemical fiber is thin enough, it may be comparable to natural silk. As a result, a competition of filaments swept the whole chemical fiber industry.

First, Japan announced to produce 0.3 denier superfine fiber around 2000. 0.3 denier means 10000 meters long silk, with a weight of 0.3 grams. This was once considered the upper limit of industrial spinning technology, and no one in the world will break through it.

Soon, China produced 0.15 denier superfine fiber, and the superfine record decreased by 50%. Today, the Chinese have broken their own world record!

Chinese engineer Bian Shuchang has produced 0.05 denier superfine fiber. It is equivalent to splitting the fiber close to one fiftieth of the hair into three pieces. This kind of microfiber also has a nice name—— "Island fiber" 。

Although the history of chemical fiber is only 130 years, the man-made fiber we have created is even more than the natural cotton, linen and wool.

Popular throughout the country in the last century Dacron No pulling, no pulling, no washing and no drying;

　　 Vinylon , moisture absorption like cotton, with strength exceeding that of cotton;

　　 acrylic fibres Known as synthetic wool, it is used to make suits with neat shape and not easy to fold;

　　 spandex Good elasticity, often make underwear or sportswear;

　　 polyester fiber The filament fabric has pearl light, smooth feel and is comparable to natural silk;

If you put Island fibre Interleaved into cloth, its performance is even better than that of natural suede. It is fine waterproof, and is a superior fabric. People often choose it to wipe precision instruments.

In China, the legend from oil to silk is staged every day. Wujiang, once the "Silk City" of Suzhou, has now become a world chemical fiber city. Globally, more than 70% of the world's annual chemical fiber consumption comes from China.

　　 As thin as hair, as light as feather, as strong as steel! Uncover the "king of new materials"!

Its figure often appears in high-end sports equipment, often helping athletes to create new world records;

The fan blades made of it are lighter and stronger, which will bring higher power generation efficiency and stronger unit stability;

In the aerospace field, this fiber even launched a fierce attack on metal. People often choose it to replace metal, and take the amount of this fiber as an important symbol to measure the level of a country's aerospace equipment.

It is famous carbon fibre 。

In 1880, Edison first discovered carbon fiber in order to make a long bright electric lamp, but the early carbon fiber was easy to break and break, leading to a long dormancy period. A hundred years later, people will awaken carbon fiber, upgrade the formula and process, and let carbon fiber display its talent and shine. At this time, carbon fiber, which is as thin as hair, as light as feather, and as strong as steel, will return to the Jianghu and win the title of "king of new materials" at one stroke.

Today, carbon fiber has already established itself in the industrial field, but it is as expensive as gold and as difficult to manufacture as a chip. There are only a few countries in the world that can produce it, and China is one of them.

Chinese engineers have announced that they can manufacture T1000 carbon fiber! A bundle of one meter long T1000 carbon fiber weighs only 0.5g, but it can bear the force of 500kg. Taking a bundle of chopsticks thick and thin, it can pull two C919 domestic large aircraft. In the future, T1000 carbon fiber will strongly support the manufacturing of China's national heavy weapons, including large passenger aircraft, carrier rockets, and the construction of many super projects.
