In the production, processing and use of ordinary textiles, it is easy to generate static electricity due to friction and induction. For synthetic fiber products with generally low moisture regain, the accumulated electrostatic charge is easy to cause dust adhesion, clothing entanglement with limbs, resulting in discomfort, and can cause the increase of blood pH value, the decrease of calcium content in blood, the increase of calcium content in urine, the increase of blood glucose and the decrease of vitamin C content. High electrostatic voltage can produce electric shock to human body. Ion bars can be used to quickly eliminate high static electricity on the surface of textiles. We can customize ion bars with different functions and models according to the needs of customers' on-site production environment, so as to better meet customers' needs and solve the problem of static electricity.
