Introduction of polyester filter bag
Polyester needle felt is adopted polyester filament needle carpet fiber classics non-woven acupuncture process heat sty ling, singeing, pressure with light made with three-dimensional structure, space distribution uniformity, the surface is smooth non-woven fabric.
Feature of polyester filter bag
It has such advantages as large porosity, good air permeability, high efficient of dust collection, easy separation, stable chemical property, long working life,low price etc. it can not only filtrate normal temperature gas, water, oil but also corrosion
gas with acidity, alkalinity.
Application of polyester filter bag
It is widely used in such fields as steel, non-ferrous metal, chemical industry,cement, medicine, foodstuff etc.
