Standard Wearing Guidelines for Antistatic Clothing
For operators, standard antistatic clothing styles present two possible discharge paths. It's generally believed that wearing pure cotton work clothes prevents static electricity buildup and is therefore safe; however, this view is one-sided. Cotton fabrics can even carry a higher charge than some synthetic fabrics. Therefore, in dry climates, one cannot expect pure cotton products to eliminate the static electricity hazards of antistatic clothing in all situations. One is the discharge between the fingertips and a grounded conductor; the other is the discharge between the work clothes and a grounded conductor. Both types of discharge can damage static-sensitive devices. While antistatic clothing can eliminate the first type of discharge hazard, it cannot eliminate the second.
During normal production activities, the antistatic clothing worn by operators will become charged due to frequent contact, separation, and friction with external surfaces, between layers of clothing, between underwear and skin, and even between the soles of shoes and the ground. This charging is particularly amplified when wearing highly insulating synthetic fabrics. Static charges on clothing and shoes gradually dissipate across the entire surface according to the law of charge dissipation on a dielectric, eventually reaching equilibrium and forming a certain static voltage on the clothing. Since the human body is a good conductor, the charge on clothing can cause the skin to become charged due to electrostatic induction, also forming a certain static voltage.
Generally, people often only focus on eliminating static electricity from the skin, neglecting or not giving sufficient importance to eliminating static electricity from anti-static clothing. This needs to be strictly improved to effectively prevent the harmful effects of static discharge from the human body! Therefore, we should coordinate and implement effective protective measures for the anti-static clothing that must be worn.
