Zhejiang polyester needle felt dust bag, dust bag, bag at room temperature, long life

Polyester filter bag large selection of quality fine denier fiber yarns, with advanced production equipment PET (polyester) fiber needle punched filter felt, can be a variety of quantitative fibers are uniformly mixed, and then mixed open multiple units and combed cotton fiber unit in favor between different means net composite fiber layer, dilution transformation. Bag Features: polyester needle felt filter bag with a high void space, good air permeability, high dust collection efficiency, long life and other advantages of ordinary cloth mat class specific. Its moderate temperature levels, instantaneous 150 ℃, which is moderate acid, alkali, and has very good wear resistance. So it is felt type filter using a variety of the largest. Weight 350g / m2 ~ 800 / m2, thickness of 1mm ~ 4mm, width of 3.4 or less can I plant production, and cut to various widths. Surface treatment in accordance with the different requirements of working conditions, can singeing, calendering or coating. Bag Advantage: The surface smoothness of the polyester filter bag filter cleaning effect on the air permeability of the woven fabric used to make the bag when ventilation is better to use a small amount of woven fabric. Therefore, to ensure the filter media to achieve higher accuracy, raising the air permeability and surface smoothness filter and reduce dust adhesion and lower operating resistance. Polyester needle felt series filter using nonwoven needling process, and made with a heat-setting and other treatment methods, widely used in industrial catch dust, dust control and so on. Polyester needle felt filter after water repellent and oil-treated because of their water repellent properties, application in high moisture content or oil containing a small amount of dust can be prevented paste bag and prolong life. Polyester needle felt filter surface covered with a layer of a composite microporous polytetrafluoroethylene (PTFE) film, with a smooth surface, water repellent, breathable, easy cleaning features, high filtration efficiency, low resistance, low energy consumption , long life, so that "surface filtration.
