using non-woven needling process, and made by heat setting and other processing methods, widely used in industrial dust, dust control and so on. The polyester Needle Felt
good air permeability, after heat treatment, the surface is smooth, not easy deformation, easy cleaning. The polyester needle felt water and oil repellency after treatment because of its hydrophobic properties, used in the dust with high moisture content or containing a small amount of oil, can prevent the paste bag, prolong the service life of coated polyester needle felt. The surface of a layer of composite microporous polytetrafluoroethylene (PTFE) films with a smooth surface, hydrophobic breathable, easy cleaning and other characteristics. High filtration efficiency, low running resistance, low energy consumption, long service life, truly realize the surface filtering.
The Filter Felt divide into PPS FILTER FELT, PTFE FILTER FELT, ARAMID FILTER FELT, ACRYLIC FILTER FELT, PET FILTER FELT ETC.
