The utility model discloses a dacron mixing conductive three-proof spunlaced felt. The structure of the filtering felt is that bonding fiber layers are ejected into the upper surface and the lower surface of a piece of decron polyester filament base cloth through high-pressure water flow. The dacron mixing conductive three-proof spunlaced felt has the advantages of being strong in water-proof, oil-proof and static-proof performance, high in filtering accuracy, long in service life and good in filtering performance.
