Description

Polyester anti-static dust bag filter cloth are made of anti-static polyester needle felt production, conductive material of the conductive fiber yarn or chemical fiber mixed with conductive fibers incorporated in the warp yarns of the base fabric of the production needle felt, excellent anti-static performance.

Feature

  1. Good chemical resistance for weak Acids, weak Alkalis and Organic Solvents
  2. Excellent efficiency of filtration
  3. Low contraction and thermal stability
  4. Elongation and high tensile strength
