Polyester filter bag has the advantages of simple production process, fast production speed, low cost. Polyester filter bag is a kind of widely used filter bags which can work under 130℃. Polyester filter bags adopts the non-woven needle-punching process, it will be needle punched into felt after the polyester fiber is carded and laid on a fine fiber cloth with a staggered arrangement of fibers and uniform distribution of voids. The filter material has high strength, good elastic recovery performance, stable fabric size, good wear resistance, large void ratio, good gas permeability, long service life, good dust removal effect, good mechanical properties and resistance at normal temperature below 130 °C with the acid and alkali resistance ability. Due to the low price of polyester, polyester needled felt filter bags is a cost-effective filter media.
