Polyurethane "Seamless" Spacesuit

If the polyurethane layer is damaged, the colloid will exudate and solidify at the damaged part and automatically plug the leak.

According to Professor Wu Guoxing, Professor of Aerospace Medicine Engineering Institute of China, in the most expensive clothes in the world, a set of extravehicular spacesuit includes 19 items: upper garment, clothing lower body, upper limbs, gloves, helmet, liquid cooling ventilating suit, male urine collection bag, female urine collection bag, sunshade board on helmet, drinking bag, communication device, main life support system, auxiliary oxygen cylinder and so on.

The spacesuit part is made up of 14 layers.

The function is gradually improving, and materials are becoming more and more abundant, so the cost is higher and higher.

Space expert Liu Dengrui explained.

"Yang Liwei wears more than 130 new materials in his spacesuit."

Chinese textile material expert Yao Mu said in an interview with the media that in order to prevent inflation, all kinds of rings, zippers, sewing threads and special liners were specially made on spacesuit.

According to the performance of different parts, spacesuit selection materials are also different, the same material also has many different categories, such as rubber, but the different types of rubber used in spacesuit are totally different.

It can be said that every inch of spacesuit is not simple.

Because spacesuit is usually only one piece in the world and can not be produced in large quantities, the raw materials for producing spacesuit are also very small. This undoubtedly increases the production cost.

Moreover, the production environment of spacesuit is very strict. There must be hundreds of processes in space design.

According to "Tianfu Morning Post" reported that God seven spacesuit from head to toe by a special textile company in Chengdu to provide raw materials, all aspects of spacesuit should be connected with high-strength silk.

The extravehicular spacesuit of God seven is made of high grade mixed fiber and has the characteristics of high strength, high temperature resistance, impact resistance and radiation protection.

In addition, the raw materials have good elasticity, and the inner layer of the fabric is also covered with rubber, which is able to resist ultraviolet radiation and strong cosmic radiation.
