"Shenzhou 13 Manned Spaceship Returns Three People" Warm Clothing "And" Body Protective Clothing "Gather Textile Strength

　　 At 9:56 Beijing time on April 16, 2022, the shenzhou-13 manned spacecraft re-entry module successfully landed at Dongfeng landing site, and the shenzhou-13 manned mission was a complete success.

"Feeling good" group Zhai Zhigang, Wang Yaping and ye Guangfu, astronauts of Shenzhou 13 All of them left the capsule safely and smoothly, ended their "space business trip" and returned to the earth, which has been separated for half a year, thus marking a successful end to China's longest manned space flight. This is the 21st mission of China's manned space program since the project was approved and implemented. It is also the second manned mission in the space station stage. Behind this mission, the textile people once again contributed "textile strength" to China's aerospace industry.

　　 Astronauts' warm clothes

At about 10:43 a.m. on April 16, the three member group of Shenzhou 13 "space business trip" began to leave the cabin. After each astronaut leaves the cabin, the staff immediately put on "warm clothing" for them.

The blue equipment is called astronaut ground thermal device Professor He Yang, director of Beijing National Costume Museum Design has the function of displaying national image.

According to He Yang, "Shen 13" uses the floor thermal equipment of "Shen 11". Because astronauts stay in orbit for a long time, they may not be able to adapt to the earth's gravity immediately after landing; And the climate at the landing site is cold. In order to ensure the health of astronauts, it is necessary to design ground thermal insulation devices. According to the regulations, the floor thermal insulation device consists of sleeping bag and blanket. The sleeping bag will put the astronauts in the spacesuit, and the blanket will keep warm and take care of them. In order to adapt to the natural bending state of astronauts in the armchair, sleeping bags are specially made into conformal bending style; Professional outdoor fabrics are used to keep warm and windproof.

According to the temperature of Dongfeng landing site, only sleeping bags were used after the astronauts left the cabin.

The color of sleeping bags and blankets in the ground thermal insulation device is based on the color of the logo of the Chinese astronaut center, and is considered to be unified with the visual image of the space center from the three aspects of lightness, hue and color to form an identifiable color system. The flower patterns of the prosperous Tang Dynasty are combined in the traditional way of four directions, seeking changes in the order, having rich details and aesthetic feeling in the near view, and forming a background full of rhythm and rhythm from a distance, which helps to set off the heroic posture of Chinese astronauts. The flower patterns with prosperous weather and Chinese style convey a festive and cordial atmosphere, and let the flowers cluster around the aerospace heroes of the motherland.

It is reported that Professor He Yang is the designer of the patterns of sleeping bags and the colors of working clothes for astronauts in the "Shenqi", "Shenjiu" and "tiangong-2" missions. She has been designing patterns and patterns for sleeping bags in the cabin since Shenzhou 7. "At that time, the concept of" auspicious clouds flying into the sky "was used, and there were various cloud patterns on the sleeping bag," He Yang said. Because the sleeping bag will remain in the orbital module and can not be recycled, it needs to be made again every time.

　　 "Protective clothing" of space station

In addition to the "warm clothing" of astronauts, what is rarely known is that during the 183 days of astronauts' stay in orbit, basalt fiber cloth produced by Zhejiang Shijin Basalt Fiber Co., Ltd. has been quietly guarding them in the space station as "body protective clothing".

With the development of space industry, the number of space debris continues to increase, which seriously threatens the safe operation of spacecraft. It is reported that the enemy of the space station is actually debris and micro stars formed by space debris. At present, more than 18000 large-scale space wastes have been detected and numbered. In addition, the total number is as high as 10 billion, which can only be resisted by the space station itself. In 2018, the Russian Soyuz spacecraft claimed an air leak due to damaged cooling pipes. Last month, the small space station's 18 meter long space debris was detected in time, and the subsequent inspection by space crews was more serious.

In order to prevent similar incidents, basalt fiber cloth is used to fill the structural materials of the space station to prevent the occurrence of similar events, so that the space station can protect the high-speed impact of debris up to 6.5 mm in diameter. The basalt fiber cloth, jointly developed by the space station of the Fifth Research Institute of China Aerospace Science and Technology Corporation and Zhejiang Shijin Basalt Fiber Co., Ltd., has been used in China's space station. As the key material of space debris protection structure, it can effectively crush, melt and even vaporize the projectile, and reduce the projectile speed, The ability of the space station to resist the impact of space debris with a speed of 6.5km/s is increased by more than three times, and the on orbit reliability and safety of the space station are greatly improved, which exceeds the protection design index of the international space station.

"We started to develop basalt fiber cloth in 2014. After more than 20000 tests, we succeeded and exceeded the protection design index of other countries' international space stations." The person in charge of Zhejiang Shijin Basalt Fiber Co., Ltd. said that this year marks the 30th anniversary of China's manned space flight. Over the past 30 years, China has been accelerating its pace from a space power to a space power. In the future, it will move towards a more far-reaching deep space, and there will be more and more technologies that need to be broken through.
