Anti-static condition of cotton fabric
It is generally believed that wearing cotton overalls can prevent static accumulation of clothing and is therefore safe. Actually, this view is one-sided. This is basically the case when the relative humidity of the air is higher than 50%; and when the relative humidity is relatively low, the charge amount of the pure cotton product is significantly increased. Tests have shown that at a relative humidity of less than 30%, the charge of a cotton fabric is comparable to that of polyester; and when the relative humidity is less than 20%, the charge of a cotton fabric is even higher than that of some chemical fabrics.
Therefore, in dry climate areas, it is not expected to use any cotton products to eliminate the electrostatic hazard of clothing under any circumstances. Based on the above reasons, in order to effectively prevent the electrostatic discharge hazard of the human body static electricity, the operator must wear anti-static overalls.
