The anti-electrostatic filter bags produced by Shanghai Vinson are of two types, and the effects of their use are also different; in addition to the process of producing ordinary needle felts, they are also required to be used in warp yarns of base fabrics for the production of needle felts. The incorporation of conductive fiber yarns or the incorporation of conductive fibers or conductive materials in chemical fibers has made antistatic needle felts with better 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.
