Polyester needle felt is the main filter material in the bag filter. 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. 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, and good mechanical properties at normal temperature (below 130 ° C). And acid and alkali resistant. Due to the low price of polyester, polyester needle felt is the most cost-effective filter medium at low temperatures.
Polyester needle felts are often mixed with antistatic fibers, singeing, calendering, water-repellent and oil-proof impregnation according to the characteristics of dust from different manufacturers. The polyester needle felts have increased the easy-to-clear ash in the original performance. Dust stripping fast), water and oil proof (anti-condensation), anti-static properties, forming a series of products.
