General clothing can carry a high static electricity, especially now most of the clothing is chemical fiber, can produce thousands of thousands of volts of static electricity. When the human body carries out various activities, the static voltage value on the clothing has greatly exceeded the electrostatic discharge damage threshold of many electrostatic sensitive devices, so it is possible to cause damage to sensitive devices when touching or approaching these components. So there are anti-static clothes, then some people ask, anti-static work clothes are really useful? I take you to understand.
Some people believe that wearing pure cotton overalls can prevent the accumulation of static electricity in clothing, so it is safe. In fact, this view has a one-sidedness, only when the relative humidity of the air is higher than 50%, and when the relative humidity is relatively low, the electricity of pure cotton products is significantly increased.
The results show that when the relative humidity is lower than 30%, the electric capacity of pure cotton fabric is equivalent to that of polyester fabric. When the relative humidity is less than 20%, the electric capacity of cotton fabric is even higher than that of some chemical fiber fabrics. Therefore, in dry climates, cotton products can not be expected to eliminate electrostatic hazards in clothing under any circumstances. At this time, it is necessary to wear anti-static work clothes to ensure the quality of the product and personal safety.
Anti-static work clothes are required to wear protective clothing in flammable and explosive places. Anti-static fabric is made of anti-static fiber mixed with cotton and poly-cotton fiber. Its electrical conductivity is higher than the requirements of Japan’s “electrostatic safety Guide”, the charge density is less than 7, the durability is strong, safe and reliable. For the above reasons, in order to effectively prevent the damage of static electricity on the human body, the operator must wear anti-static work clothes. In addition, it is necessary to wear anti-static shoes and other supporting measures to more effectively ensure human safety.
