Polyester needle felt series filter material using non-woven acupuncture process, and by heat setting and other treatment methods, widely used in industrial dust, dust control and so on. Polyester Needle felt filter permeability is good, after heat treatment, the surface smooth and smooth, easy to deformation, easy to clean. Hydrophobic and oil-repellent processing of polyester needle felt filter because of its hydrophobic properties, used in high moisture content or with a small amount of oil dust, can prevent paste bags, extend the service life. (PTFE) film, with a smooth surface, hydrophobic, easy to clean, and other characteristics, high filtration efficiency, low running resistance, low energy consumption. , Long life, the real realization of the "surface filtration."
