Polyimide is leaf-shaped structure with a larger filter surface, and always embedded in the surface of other needle felt with different material to improve the filter efficiency.

During the weaving process, we add the anti-static yarn regularly. It is used for explosive industry dust collection to prevent explosion caused by static flame during the production. It is also used for solid-liquid separate. For some sticky filtrate, it makes cake removing more easily. We generally adopt the stainless steel fiber for anti-static

anti-static felt specifications: Product name:anti-static polyester needle felt(anti-static scrim) Material: polyester staple fiber Scrim:polyester anti-static scrim

Tensile strength (n/5 x 10cm): a) Warp: 1,000 b) Weft: 1,200 Tensile elongation: a) Warp: <20% b) Weft: <25% Permeability (10-3m3/m2.S): 150 - 350 Working temperature (oC): a) Continuance: 130 b) Instant: 150 Surface treatment: singeing, calendering, heat setting

Except technic to manufacture common needle punched felt, it also require to replant electric conduct fiber into the scrim or blend the chemical fiber with electric conduct fiber and other electric conduct material. Our company can make both filter needle punched felts.

During the running of dedusting bags, the gas includes moist, hygroscopic and deliquescent powders. It will create the water or oil membrane on the surface of powder to increase the cohesion, but it will make the dust removal more difficult. After treatment, those filter material can form the molecular barrier around the fiber

Liquid Filtration Needle Felt 1.water repellent punched felt 2.use Teflon coating 3.can apply to Steel Cementing Smelting

The material is even in thickness, the steady size of hole and strengthening the tensility. The precision is among 1-200 microns, the material is mainly polypropylene or polyester.
