Fibreglass Needle Felt Industrial Filter Cloth PTFE 220cm High Performance

What is Nonwoven Needle Felt Filter Fabrics?



Needle felt is a kind of non-woven filter fabric specially used for dust
collector filter bags. It is a major filter material for industrial air
filtration and dust removal. The needle felt is made of randomly arranged
fibers needle punched on the scrim fabric, after that the fibers are close-
knitted to form a tortuous three-dimensional stereo-structure, which is
different from the traditional woven filter cloth composed of warp and weft
yarns. It makes dust particles adhere to the surface of the filter material and
form an initial layer of dust ( Filter cake), with the remarkable
characteristics of small pore size, high filtration efficiency and low air
resistance, greater air permeability and excellent dust particle capture.

What is needle felt filter fabrics features and advantages?



The irregular fibers in the needle felt filter fabrics are arranged in three
dimensions, which could give full play to the dust capture capacity
This structure easy to form the dust filter cake layer in the initial of
filtration production, and is no straight pore after dedust. It makes the air
filter bags has a high and stable dust collection efficiency.
The statical dust capture rate of needle felt filter cloth could up to 99.5% ~
99.99%
The porosity of needle filter felt is as high as 70% ~ 80%, which is 1.6 ~ 2.0
times of woven filter fabrics, it gets larger air permeability and lower air
resistance
