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. Because of the low price of polyester, polyester needle felt is a 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), antistatic properties form a series of products.

Compared with general woven filter materials, needle-punched filter felts have the following advantages:

Large porosity and good gas permeability can improve equipment load capacity and reduce pressure loss and energy consumption. The needle-punched filter felt is a short-fiber filter cloth which is staggered and has a uniform distribution of voids, and the porosity is more than 70%, which is double that of the woven filter cloth. The use of acupuncture as a filter bag reduces the size of the baghouse and significantly reduces energy consumption.
The dust is highly efficient and the gas emission concentration is low. The actual measurement shows that the efficiency of filtering 325 mesh talc powder (median diameter 7.5μm) can reach 99.9-99.99%, which is an order of magnitude higher than flannel. Gas emission concentrations can be significantly lower than national standards
The surface is finished by hot rolling, singeing or coating, the surface is smooth and smooth, not easy to block, not easy to deform, easy to clean and long service life. The service life of needle felt is generally 1-5 times that of woven filter cloth.
Chemically stable. Not only filters normal or high temperature gases, but also filters aggressive gases containing acids and bases

Product Feature:

Large porosity and good gas permeability can improve equipment load capacity and reduce pressure loss and energy consumption. Needle filter felt is utilized
Short-fiber filter cloth with staggered arrangement and uniform distribution of voids, the porosity can reach more than 70%, which is double that of woven filter cloth. The use of acupuncture as a filter bag reduces the size of the baghouse and significantly reduces energy consumption.
The dust emission efficiency is high and the gas emission concentration is low. The actual measurement shows that the efficiency of filtering 325 mesh talc powder (median diameter about 7.5μm) can reach 99.9-99.99%, which is an order of magnitude higher than flannel. Gas emission concentrations can be significantly lower than national standards
The surface is finished by hot rolling, singeing or coating, the surface is smooth and smooth, not easy to block, not easy to deform, easy to clean and long service life. The service life of needle felt is generally 1-5 times that of woven filter cloth.
Chemically stable. It not only filters normal or high temperature gases, but also filters aggressive gases containing acids and bases.
