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.
Needle felt for dust collector filter bags
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
Main Characteristics of a Non-woven Needle Filter Felt:
Weight, the most rudimental and important data of a needle felt,also is an important factor affecting the price of the filter fabrics
Thickness, too thick will lower the fabric strength and filtration efficiency, meanwhile too thin will lower the wear resistance and increase air resistance
Air permeability, the crucial parameter of a filter fabric
Tensile strength, an important parameter to determine the quality of a needle felt filter fabric
Breaking strength, indicate the robustness of a needle felt filter cloth
Wear resistance, include planar wear, flexual wear and crease wear, it depends on material property, fiber shape and fabric structure
Temperature resistance, include continuous working temperature and surge temperature, one of the most important parameter to choose the suitable needle felt for the dust collector bags
Dust removal characteristics
1.Resistance coefficient of clean filter material
2.Statical dust removal rate
3.Dynamic dust removal rate
4.Dynamic air resistance
Water & Oil resistance
1.Heat setting, the heat setting of needle felt is to eliminate the stress in the fabric to obtain a stable dimension and smooth surface, which are important to the reliability and service lifetime of the air filter bags.
2.Sing, burn off the floating fibers on the surface of the needle felt filter material to make the surface smoother and easy to dust removal.
3.Calendar, hot calendering makes the surface of the needle felt filter cloth smoother, with uniform thickness and air permeability. Although the initial resistance will be slightly bigger, it remains the particles on the surface, the dust does not easily enter the deep layer and is easier to dedust. This helps to reduce the air resistance of the bag housing dust collector, and increase filtration efficiency and service life of the filter bags.
Coating, including water & oil resistance coating and PTFE coating treatment, It avoids agglomeration on the surface of the filter fabrics when there is condensation in the bag filter housing.
4.PTFE treatment, including PTFE dipping and PTFE membrane
PTFE impregnation(dipping) treatment reduces the fabric pore size, improves the filtration efficiency, moreover, enhance the heat resistance, corrosion resistance, oxidation resistance and abrasion resistance properties of the needle felt filter fabrics.
5.PTFE membrane is an ideal solution to control the pollution PM2.5
