Other name: Felt anti-static filter bag; Polyester dust collector filter bag; Polyester dust filter bag; Filter bag dust collector; Flour dust collector filter bag; Dust collector filter sock; Dust filter sock; PE dust filter bag.

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.
Advantage: High void;  Good ventilation;  High dust collection efficiency and long service life;  Its temperature resistance is moderate, and it can reach 150°C in an instant;  It is moderately resistant to acid and alkali, and has very good wear resistance.
Application:Mainly used in cement building materials; Building materials; Steel; Non-ferrous smelting; Furniture; Chemicals; Machinery casting; Crushing and polishing; Food; Medicine; Feed mill grinding machine and other industries.
