According to the relevant person of Donghua University (formerly China Textile University), where the spacesuit of China manned spacecraft was made, the spacesuit was made last year and tried on many times.

Spacesuit consists of clothing, helmet, gloves and space boots. The most complex clothing consists of 14 layers: the innermost layer is the lining of liquid-cooled ventilation clothing; Outside the lining is a liquid-cooled ventilation suit, which is made of nylon elastic fiber and many plastic tubes for conveying coolant. There are two pressurized airtight layers outside the liquid-cooled ventilation suit, and another limiting layer limits the outward expansion of the pressurized airtight layer; Outside the limiting layer is a heat-proof micrometeorite dust-proof suit, with 8 layers in total, which plays the role of heat-proof micrometeorite dust-proof; The outermost layer is coat. Although the space suit has a complicated structure, it is not difficult to wear, and it can be worn in about 15 minutes.

Because spacesuit is a special kind of clothing, it usually consists of several layers, such as breathable layer, airtight layer and thermal insulation layer. It is a small sealing system, which has two functions: protection and disembarkation. This spacesuit belongs to indoor spacesuit. Except the helmet and rubber gloves, the whole spacesuit is made of a special high-strength polyester. The whole set of clothes weighs about 10 kg, and the design cost is as high as tens of millions of yuan.
