Dust filter bag

The nonwoven needling process, and the high temperature heat, singeing, calendering and other postprocessing method, widely used in industrial dust, dust control etc..

The needle felt filter material has good permeability. After heat treatment, the surface is smooth and smooth. It is not easy to be deformed and easy to dust. The hydrophobicity and hydrophobicity treated needle felt filter material can prevent paste bag and prolong service life because of its hydrophobicity and application in high moisture content or small amount of oil pollution.

PTFE coated needle felt surface composite a layer of microporous polytetrafluoroethylene (PTFE) films with smooth surface and hydrophobic breathable, easy cleaning features, high filtration efficiency, low running resistance, low energy consumption, long service life, truly realize the surface filtering".

PTFE coating is applied on the surface of needle felt with polytetrafluoroethylene and other chemicals. It has the characteristics of smooth surface, high temperature resistance, corrosion resistance, high permeability and strong dust barrier.
