The dusting bag of polyester needled felt is the main filter material in the bag dust collector. It is a non woven needling technology. The polyester staple fiber is carding and paving the fine fiber cloth on the fine fiber fabric with a crisscross arrangement of the fiber and the uniform distribution of the gap. The filter material has great strength, good elastic recovery performance, stable fabric size, good wear resistance, large air clearance, good air permeability, long service life, good dust removal effect and good mechanical properties and acid and alkaline resistance under 130 C. Because of the low price of polyester, polyester needle felt dust bag is the most cost-effective filter medium at low.
