Polyester needle felt waterproof, oil-proof and electrostatic filter bag.
Our company polyester needle filter felt selection of 1-2.5D polyester fine denier, with high strength and low elongation yarn woven reinforced base cloth, through the needle reinforcement and post-treatment technology. In addition to the characteristics of high porosity, good permeability, acid resistance and moderate alkalinity of ordinary felt filters, the product has very good wear resistance, so it is a variety of felt filters widely used. G weight from 350g/m2-800g/m2, thickness from 1mm-4mm our factory can produce. The post-treatment methods are calendering, singeing, heat setting, impregnation drying, coating and so on. It has the characteristics of stable size, easy cleaning and long service life.
The surface smoothness of filter material has a great influence on the dynamic running resistance of filter material. The initial resistance of the filter material is determined by the permeability of the filter material itself, and the resistance in operation is many times larger than the initial resistance. The running resistance depends on the smoothness of the filter surface and the cleaning effect. It is generally hoped that when the filter material ensures the same filtration efficiency, the larger the air permeability, the better, that is, the lower the resistance, the better, because this can save a lot of energy. In the dust collector with air flow back blowing, when the air flow of the same pressure and the same air volume is used for dust removal, the dust removal effect of the woven fabric with high air permeability is better than that of the woven fabric with low air permeability. Therefore, in the case of ensuring the high filtration accuracy of the filter material, how to improve the permeability of the filter material and improve the surface smoothness, reduce dust adhesion, and reduce the operating resistance is the first topic that the filter material manufacturer should study. The air permeability of the surface resinized smooth finishing needled filter felt developed by our factory is more than 50% higher than that of ordinary calender finishing filter material, and the surface smoothness is more smooth than that of calender finishing.
