The role of anti-static clothing worn in the purification workshop
Anti-static fabrics are fabrics made by mixing conductive fibers or anti-static synthetic fibers or both at roughly equal intervals or evenly during weaving. Conductive fiber refers to a general term for fibers made of conductive materials or sub-conductive materials that are wholly or partly made of metal or organic matter, and its volume resistivity ρv is between 104 and 109Ω/cm.
According to the distribution of conductive components in the fibers, conductive fibers can be divided into three types: uniform conductive components, conductive component covering types, and conductive component composite types. The vast majority of anti-static fabrics are made of conductive fibers, especially the conductive component composite type, that is, composite fibers are used the most.
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 electricity.
