Static electricity phenomenon and conductive fiber composite fabric information

1. Static electricity phenomenon and its hazards Textile materials are generally insulating materials with high resistivity. Especially synthetic fibers, such as polyester fiber, polyamide fiber, polyolefin fiber, etc. are mostly non-polar materials with poor hygroscopicity and conductivity. Low resistance, they can generate static electricity due to friction. Since fabrics made of such synthetic fibers can carry a high potential of more than 10kv when used, discharge phenomena will inevitably occur, sometimes causing great harm to the human body or equipment. In industries such as explosives, coal mines, petroleum, chemicals, and textiles, static discharge sparks may cause fires and explosions of flammable and explosive materials. Chemical fibers and natural fibers such as acetate fiber, modified silk, wool, etc. are hygroscopic and have stronger static electricity caused by friction than synthetic fibers. However, if they are in a low-humidity environment, static electricity will still occur and cause many hazards. Therefore, people pay more and more attention to the antistatic properties of fibers and fabrics. Whether from the perspective of preventing harm or controlling product quality, eliminating static electricity hazards has become an urgent problem to be solved in people’s production and life.
