The filter fabric used in anti-static dust collector bags is typically manufactured from anti-static polyester needle felt. Its base fabric may incorporate conductive fiber yarns within the warp threads, or conductive materials-such as conductive fibers-may be blended directly into the chemical fibers. The conductive fibers are arranged on the surface of the filter medium in various configurations-including linear strip patterns and embedded conductive matrices-to impart anti-static properties. These filter bags are utilized in industries where electrostatic discharge poses an explosion risk-such as those involving flour dust, chemical dust, or coal dust-and are specifically suited for dust collection applications requiring explosion protection.
Their structure typically employs a composite design, comprising the main filter bag body encased within inner and outer anti-static protective sleeves; nylon filaments may be selected as the material for these components to enhance the overall structural integrity.
