Anti-Static Polyester Needle Felt Bag

Anti static filter bagis currently ideal dust filter material, with good ventilation energy, high dust removal efficiency, and a certain degree of acid, alkali and heat resistance, weaving process uses a multilateral brushing, increased fabric thickness, elasticity, so the dust removal effect is good, the dust removal rate can reach 99.99%. The above two products have been widely used in petroleum, chemical, metallurgy, mining, cement and environmental protection dust removal and other industries.

In addition to the process of producing a normal needle felt, the production of a polyester anti-electrostatic dust bag also requires the incorporation of conductive fiber yarns in warp yarns of base fabrics for the production of needle felts or the incorporation of conductive fibers and the like in chemical fibers. After the (ie explosion limit) in the event of static discharge sparks or external ignition and other factors, can easily lead to explosions and fires. Such as dust, chemical dust, coal dust, etc. In case of electrostatic discharge may have an explosion. In the field of bag dust collection, such dust is needed.
