Advantage of Polyester needle felt filter fabrics
1. Good tensile strength
2. Excellent resistance to acid
3. Excellent resistance to solvent
4. Economical
5. Continuous working temperature <135℃, surge 150℃
What is Polyester needle felt filter fabrics?
Polyester needle felt is the most widely used filter fabrics for
normal temperature dust removal, thanks to its versatile property
and high cost-effectiveness. Huading’s Polyester needle felt filter
fabrics is made out by long fiber scrim, and fine fiber punching on
the surface, in suitable density and thickness to ensure the
optimal filtration efficiency and tensile strength.
Various after treatment include water and oil resistance,
anti-static, PTFE membrane, etc to meet your different working
conditions.
Disadvantage of Polyester needle felt filter fabrics
Polyester is easy to hydrolysis in high temperature and high
humidity working conditions, there is ester group on the polyester
macromolecular chain, which is easy to rift in the tough
high-temperature and high-humidity conditions, this causes the
degradation of the filter material and reduces the service life.
Application of Polyester Needle Felt Filter Fabrics
1. Mining
2. Cement industry
3. Metal industry
4. Aluminum and non-ferrous metal industry
5. Ceramic industry
6. Quarrying
7. Plastic
8. Milk powder
9. Flour mill (used under dry conditions up to 150°C)
