[0002] As people's living standards improve, they are no longer only pursuing the practicality of fabrics, but are also beginning to shift towards functionality, beauty and style. For example, more and more people are beginning to pay attention to health, and regard antibacterial properties as a necessary property of textiles; more and more people are beginning to pursue fun and additional functions based on fun, and pay attention to the temperature-sensitive color change of fabrics in order to achieve a more beautiful external visual effect. With the development of dyeing and finishing technology, chemical technology, etc., the ways to give textiles functionality are becoming more and more diverse.

[0003] Static electricity is a common physical phenomenon. As people do not know much about its generation, they often think that only static electricity discharges above several thousand volts can be felt. But in fact, static electricity at lower voltages can also have adverse effects on human health. Static electricity can irritate human skin, reduce skin moisture, increase dandruff, and cause dry and itchy skin. This phenomenon is particularly obvious in winter, because the air is dry in winter, and static electricity is easily generated between human skin and clothing. The skin of the elderly is relatively dry and more susceptible to static electricity.
