Anti-static dust bag are used (conductive fibers are incorporated in the production of needle felt fabric yarn warp or mixed with conductive fibers in the chemical fiber and other conductive material) anti-static polyester needle felt production, with excellent anti- static properties, for surface dust, chemical dust, coal dust, etc. In case of electrostatic discharge potentially explosive industry, is the best choice of proof collecting industrial dust concentration reaches a certain level after (ie explosive limit) in case electrostatic discharge spark ignition or external factors, could easily result in an explosion and fire, such as: surface dust, chemical dust, coal dust, etc. In case of electrostatic discharge may have exploded in areas such as the dust bag filter required. bag to collect, requires making dust bag filter media with anti-static properties, the company absorb and digest foreign technology, according to the needs of the domestic blast furnace gas collecting coal mill and cement mill collecting coal and other industries, development and production Antistatic filter needle felt, anti-static cloth in addition to the production process with the production of an ordinary needle felt, also called conductive fibers are incorporated in the production of needle felt fabric yarn warp or mixed with conductive fibers or chemical fibers conductive material, three of my financial company of these two types of anti-static cloth can be produced. Its performance in a leading domestic level, has been the authoritative department.
