Anti-static clothing to eliminate static principle
1. First of all, anti-static work clothes refer to work clothes that are sewn with anti-static fabrics to prevent static electricity accumulation on clothing. The antistatic fabric is a fabric obtained by mixing conductive fibers, antistatic synthetic fibers, or a mixture of the two at approximately equal intervals or uniformly during weaving.
2. Conductive fiber refers to a general term for fibers made of conductive materials or sub-conductive materials that use metal or organic materials in whole or in part. Its volume resistivity ρv is between 104 and 109 Ω / cm. According to the distribution of conductive components in the fiber, conductive fibers can be divided into three types: uniform conductive component type, conductive component covering type and conductive component composite type. The vast majority of anti-static fabrics are made of conductive fibers, especially the composite type of conductive components, that is, the most used composite fibers.
3. The anti-static overalls made of conductive fibers are added to the chemical fiber fabrics. The elimination of electricity is based on the two mechanisms of charge leakage and neutralization. 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 via the conductive fiber; when it is not grounded, it is eliminated by the weak corona discharge of the conductive fiber.
