Anti-static work clothes are a kind of shielding clothes
Today's electronics factories all have anti-static work clothes, but the role of anti-static work clothes is not very clear. Some people think that if you wear an anti-static wrist strap and wear anti-static shoes, anti-static work clothes are optional. The static electricity on the clothes or clothes will be discharged to the ground through the anti-static wrist strap and anti-static shoes. In fact, this is a common misconception.
Most clothes are insulated or have insulating properties (depending on the amount of sweat in the clothes, thickness, cloth, number of layers, etc.). The charge will not move on the insulator, it will remain on the insulator all the time, so the static electricity will be neutralized after a certain time.
Therefore, your sleeves, belts, etc. may carry a voltage of several thousand volts (the electric field it generates is very strong for the surrounding conductors), which may cause charges to be induced on nearby isolated conductors. The harm is unimaginable. Therefore, staff need to wear anti-static work clothes to shield the insulated clothes to minimize the static field generated by the clothes.
