Usually, when the concentration of industrial dust reaches a certain level (i.e. the explosion limit), when encountering factors such as electrostatic discharge sparks or boundary points, high-temperature resistant needle felt is highly likely to cause explosion and fire. Such as: flour dust, chemical dust, explosive dust, etc. If there is a possibility of explosion in the event of electrostatic discharge, in the field of bag dust removal, if these dust needs to be collected using cloth bags, it is required that the produced cloth bags themselves have anti-static functions. In addition to the production of ordinary needle punched felt technology, the production of anti-static filter materials also requires the inclusion of conductive fiber yarn in the base fabric warp yarn of the needle punched felt production.
