The anti-static processing method of the fabric generally comprises the following steps: firstly, the fabric is subjected to after-treatment by using an antistatic finishing agent; grafting modification of fiber, blending and interweaving of hydrophilic fiber for the purpose of improving the moisture absorption of the fabric; ③ blending or embedding the conductive fiber; the action mechanisms of the first two methods are all to improve the moisture regain of the fabric, reduce the insulativity and accelerate the static leakage. Therefore, if the processing effect is not durable or significant in a dry environment or after multiple washings, the processing effect is usually applied to common clothing fabrics. The third method can solve the static problem of textile with high efficiency, so it is widely used in producing antistatic working clothes. The fabric is post-finished with an antistatic finishing agent. The composite fabric is a novel material formed by bonding and laminating one or more layers of textile materials, non-woven materials and other functional materials. The carbon fiber is a special fiber composed of carbon elements, has the characteristics of high temperature resistance, friction resistance, electric conduction, heat conduction, corrosion resistance and the like, is fibrous and soft in appearance, can be processed into various fabrics, and has high strength and modulus along the fiber axis direction due to the preferred orientation of the graphite microcrystal structure along the fiber axis.
