When the concentration of general industrial dust reaches a certain level (i.e., explosive limits), factors such as electrostatic discharge sparks or external ignition can easily lead to explosions and fires. 

Antistatic polyester needle-punched felt incorporates antistatic fibers to provide excellent antistatic performance. It is used in industries where there is a potential for explosions due to electrostatic discharge, such as in flour dust, chemical dust, and coal dust. Also as part of baghouse dust collectors, plate and frame filter presses, belt filter presses, vacuum suction filters, and smoke dust removal systems.
