The antistatic fabric is a fabric obtained by mixing conductive fibers or antistatic synthetic fibers or a mixture of the two at substantially equal intervals or evenly during weaving. The conductive fiber is a general term for fibers made of a conductive material or a subconductive material using metal or organic materials in whole or in part, and has a volume resistivity ρv ~ between 104 and 109 Ω/cm.
According to the distribution of the conductive component in the fiber, the conductive fiber can be classified into three types: a conductive component uniform type, a conductive component covering type, and a conductive component composite type. Most of the anti-static fabrics are made of conductive fibers, especially the conductive component composite type, that is, the composite fiber is used most.
The anti-static overalls made of conductive fibers are added to the chemical fiber fabric, and the power-dissipation is based on two mechanisms of charge leakage and neutralization. When grounded, the static electricity on the fabric is neutralized by the corona discharge of the conductive fibers, and can also be discharged to the ground via the conductive fibers; when not grounded, the electricity is dissipated by the weak corona discharge of the conductive fibers.
