The clothes are basic necessities of life, and besides the effect of beauty, the heat preservation is an important effect of the clothes in the global temperate zone and cold regions. Cotton, animal hair, chemical fibers and the like are widely applied to manufacturing of warm clothes. Most commonly, the temperature of the human body is maintained by increasing the number of pieces of the worn clothes, and the proper temperature of the human body is maintained only by increasing the thickness of the fabric, so that the requirement of people on the consumption of clothing products cannot be met, and the produced clothes which are only used for increasing the thickness of the fabric to maintain the proper temperature of the human body are troublesome, inconvenient and not beautiful. In addition, radiation protection, especially against ultraviolet radiation, is a problem that people begin to think about when wearing clothes. Traditional clothes rarely have an ultraviolet-proof function, and the function is added only to special sun-proof clothes. Professional sun-blocking clothes can play the effect of ultraviolet protection, radiation protection, but usually the price is high, is not suitable for general crowd. The sun-proof clothes with low price has poor ultraviolet effect, and even the sun-proof function is not much different from that of common clothes. In addition, for garments, antimicrobial properties should also be considered, where a large number of bacteria are present in the air or in contact with it, and intimate undergarments may be frequently changed and washed, but have allergic or other skin problems; the frequency of washing the outer-wearing overcoat is low, and the washing cost is higher when the outer-wearing overcoat is frequently changed, so that the clothes with the antibacterial function tend to be.
