Polyester blended anti-static needle felt is a kind of needle punched nonwoven fabric, which is manufactured by evenly mixing anti-static fibres into polyester fibres during the needling process. The colour is grey. The needle felt is burnished, calendered and heat set with smooth surface.
The surface resistance can reach 10^3-10^8, with excellent anti-static effect.
Polyester blended anti-static needle felt effect is better than stripe anti-static and square anti-static, suitable for the use of higher requirements for anti-static environment, such as blast furnace gas de-dusting and cement plant de-dusting.
