The anti-static filter bags produced by our company are of two types, and the effects of their use are also different; in addition to the process of producing ordinary needle-punched felts, it is also required in the warp yarns of the base fabrics for the production of needle felts. Incorporation of conductive fiber yarns or incorporation of conductive fibers or conductive materials in the chemical fibers provides an antistatic needle felt that is more excellent in antistatic properties.
In the industries of metallurgy, mining, chemical engineering, cement, machinery, food processing, boilers, etc., in order to allow particles and fine dust in industrial exhaust gases to not pollute the environment, high-quality results have been achieved, and good conductive fibers are available. The static electricity generated in the production process is conducted away. The surface of the felt is treated with a high temperature heat treatment, which not only avoids the occurrence of hair removal, but also ensures the filtration efficiency.
