Dissipation mechanism of anti-static clothing
Anti-static clothing refers to work clothes sewn with anti-static fabric as the fabric to prevent the accumulation of static electricity on the clothing. Anti-static fabric is a fabric formed by mixing conductive fibers or anti-static synthetic fibers or both at roughly equal intervals or evenly during weaving. Conductive fiber refers to the general term for fibers made of metal or organic conductive materials or sub-conductive materials in whole or in part, and its volume resistivity v is between 104 and 109 /cm. According to the distribution of conductive components in the fiber, conductive fibers can be divided into three types: uniform conductive component, conductive component covering type, and conductive component composite type. At present, most anti-static fabrics are made of conductive fibers, especially the conductive component composite type, that is, composite fibers are used most often. The anti-static work clothes made of conductive fibers are added to the chemical fiber fabric, and the electricity dissipation is based on two mechanisms of leakage and neutralization of electric charges. When grounded, the static electricity on the fabric is neutralized by the corona discharge of the conductive fiber, and can also be discharged to the ground through the conductive fiber; when it is not grounded, the weak corona discharge of the conductive fiber is used to dissipate the electricity. Practice has shown that anti-static work clothes can effectively suppress static electricity in clothing and eliminate or reduce the hazards of electrostatic discharge.
