Filter bag is used for high temperature exhaust filtration in chemical, carbon black, iron and steel, non-ferrous metallurgy, coal-fired boiler, refractory and cement industries, particularly suitable to bag filters with impulse or high velocity reverse air clean-down technology.
Needle felt filter cloth are made from polyester, polypropylene, polyamide, acrylic, nomex, glass fiber, pps, p84 and overlay ptfe membrane etc.
Needle felt is the main material of dust bag.

Polyamide filter cloth
Products performance: polyamide enjoys high strength between 4-5.3 cndtex, and tensile elongation stands between 18%-45%. When stretched 10%, polyamide filter cloth can restore 90% and above, which also has the highest tensile strength and abrasion-resistance among all other fibers, this makes polyamide fiber an ideal material for tire-producing. Polyamide fiber can stand concentrated alkali and weak acid, but sensitive to light and can easily get discolored and embrittled if put under the strong sunshine for a long time. Polyamide 66cannot be applied in the pharmacy and food industry, for which is poisonous.
Applications: rubber producing, ceramics, pharmacy, food industry and metallurgy.
