Can pure cotton fabrics be anti-static?
It is generally believed that wearing pure cotton work clothes can prevent the accumulation of static electricity in clothing and is therefore safe. In fact, this view is one-sided. This is basically the case only when the relative humidity of the air is higher than 50%; when the relative humidity is relatively low, the charge of pure cotton products increases significantly.
Tests have shown that when the relative humidity is below 30%, the charge capacity of pure cotton fabrics is equivalent to that of polyester; when the relative humidity is below 20%, the charge capacity of cotton fabrics is even higher than that of some chemical fiber fabrics. Therefore, in areas with dry climates, we cannot expect to use pure cotton products to eliminate static electricity hazards in clothing under any circumstances.
Based on the above reasons, in order to effectively prevent the harm of electrostatic discharge to human body, operators must wear anti-static work clothes.
