Usually industrial dust concentration reaches a certain level(that is, the explosion limit), such as the case of electrostatic discharge sparks or other factors such as the ignition point, it is very easy to cause explosion and fire. Such as: flour dust, chemical dust, explosive dust, etc.. In case of electrostatic discharge there is the possibility of explosion. In the field of bag type dust, such as with the bag to collect the dust, it is required to manufacture the bag itself with anti- static function. production of anti electrostatic filter in addition to have the production of ordinary needle felt process, it is also required to mix conductive fiber, stainless steel fiber and carbon fiber in the production of needle-felt.
