Polyester blended waterproof, oil proof and antistatic filter bag

  The polyester needle punched filter felt of our company is made of 1-2
5d high-quality polyester fine denier yarn, weaving reinforced base cloth with high-strength and low elongation yarn, and then processed by needle punching reinforcement and post-treatment process
This product not only has the characteristics of high porosity, good air permeability, acid resistance and moderate alkalinity of ordinary felt filter cloth, but also has very good wear resistance
Therefore, it is the most widely used variety of felt filter materials
The gram weight ranges from 350g / m2 to 800g / m2, and the thickness ranges from 1mm to 4mm
Post treatment methods include calendering, singeing, heat setting, immersion drying, coating, etc
It has the characteristics of stable size, easy ash removal 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 depends on the air permeability of the filter material itself, and the resistance in operation is many times greater than the initial resistance
The running resistance depends on the smoothness of the filter surface and the ash removal effect
It is generally hoped that when the filter material ensures the same filtration efficiency, the greater the air permeability, the better, that is, the lower the resistance, the better, because this can save a lot of energy
In the dust remover using air flow back blowing for dust removal, when the air flow with the same pressure and air volume is used for dust removal, the dust removal effect of selecting the fabric with large air permeability as the filter bag is better than that of selecting the fabric with small air permeability
Therefore, under the condition of ensuring the high filtration accuracy of the filter material, how to improve the permeability of the filter material, improve the surface smoothness, reduce dust adhesion and reduce the running resistance is the first topic that the filter material manufacturer should study
The surface resin smooth finishing needle punched filter felt developed by our factory has an air permeability of more than 50% higher than that of ordinary calendering finishing filter material, and the surface smoothness is more flat and smooth than that of calendering finishing
