The polyester dust filter bag is the main filter material in the dust collector bag. It is a non-woven needle punching process. The polyester staple fiber is carded and laid on a fine fiber cloth with staggered fibers and uniform gap distribution, and then needle-punched into a felt. The polyester dust filter bag has high strength and good elastic recovery performance. The fabric has stable size, good wear resistance, large void ratio, good air permeability, long service life, good dust removal effect, good mechanical properties and acid and alkali resistance at normal temperature. Rain polyester has low price, so polyester needle felt dust filter bag is the most cost-effective filter medium at room temperature. With the accumulation of dust on the surface of polyester dust filter bag filter, the efficiency and resistance of dust removal accessories will increase accordingly. When the pressure difference between the two sides of the filter material is large, some fine dust particles that have adhered to the filter material will be squeezed past, and the efficiency of the filter bag of the dust remover is lowered.
