General industrial dust in the concentration of a certain level (that is explosive limit) in case of ignition by electrostatic discharge spark or external factors, could easily lead to explosion and fire. Such as: surface dust, chemical dust, coal dust explosion in case of electrostatic discharge are possible. In bag dust areas, such as the dust bag to collect Xu
Yong, calls for making the filter dust bag with anti-static properties.
Our blast furnace gas in accordance with domestic coal mill and cement plant coal mill dust collection dust collector and other industries need to develop and produce the anti-static needle felt and filter cloth.
In addition to production of anti-static filter cloth needle felt manufacturing process general, but also requires the  production of chemical fiber needle felt or stainless steel conductive fiber is mixed with conductive material, made of the antistatic properties of anti-static needle felt even more excellent. Surface treatment according to different requirements of working conditions, can be singeing, calendering, water repellent and oil, PTFE impregnated, coated, coated and other processing.
