In addition to being beautiful and comfortable, there are also higher requirements for functionality. As a result, many functional clothing fabrics have emerged to meet the needs of consumers and bring more convenience to people's daily lives. With the continuous improvement of people's scientific concepts, green concepts such as ecology, environmental protection, and pollution-free are becoming more and more deeply rooted in people's hearts, and fabric clothing with green concepts is getting more and more attention, and its development prospect is very broad.

[0003] In the prior art, common fabrics for close-fitting use include pure cotton fabrics, silk fabrics, linen fabrics, and artificial fiber fabrics or mixed textile fabrics of these raw materials. Pure cotton fabric is widely welcomed by people because of its comfortable wearing experience. However, during use, cotton fabrics will breed a large number of bacteria and mites, and are prone to mildew and odor. Moreover, it is not suitable for soaking in washing liquid for a long time or being exposed to the sun for a long time, which brings inconvenience to users. Although people have tried to add antibacterial agents to antibacterial treat cotton fabrics, this kind of additive is not environmentally friendly and may have a certain impact on human health; Silk fabric has the disadvantages of difficult washing and maintenance, not easy to take care of, easy to deform and fade, and high price; Linen fabric has the disadvantages of poor anti-wrinkle performance, rough surface, dull and lack of luster, and is not suitable for making skin-friendly clothes; Artificial fiber fabric makes people feel uncomfortable when wearing and contacting, is easy to irritate the skin, is prone to static electricity and has poor biodegradability, and its skin-friendly performance is poor.
