The glass fiber composite needle felt filter bag combines the advantages of glass fiber + chemical fiber to overcome the shortcomings of a single material, and makes a new composite filter material with high performance and high cost performance. When the filter material is cleaned, the jitter is good, the dust is easy to peel off; the porosity is high, the gas permeability is good, the dust collection efficiency is high, and the service life is long; the high-strength and low-stretch industrial yarn is used as the base fabric to greatly increase the strength; the superior glass fiber + chemical is selected. The fiber, filter material is enhanced in acid and alkali resistance, hydrolysis resistance and wear resistance; the filter material is treated by PTFE impregnation and other post-treatment processes to improve water and oil resistance; suitable for wide working conditions, low energy consumption, maintenance Low cost;
