What is Polyester Needle Felt？
Polyester needle-punched felt is made of polyester fiber, polyester fiber, viscose fiber, polypropylene fiber, etc., and is made by needle-punching process.
Properties of Polyester Needle Felt
1.Polyester needle-punched felt is a staggered arrangement of fine short fibers with uniform pore distribution to filter air, with a porosity of 70%, which is twice that of woven filter cloth.
2.High dust removal efficiency and low gas emission concentration.
3.The surface of polyester needle-punched felt is smooth and smooth after hot rolling and singeing or coating, not easy to be blocked, not deformed, easy to clean, and has a long service life.
4.Anti-static needle-punched felt has the function of preventing anti-corrosion and electrostatic discharge of blast furnace gas and coal mill bag dust collection in cement plant, and deriving static electricity.
The main use of polyester needle felt
Products are widely used in: machinery, metallurgy, mining, forestry, textile, electromechanical, communications, instrumentation, transportation. Surface treatment of products in aviation, ship mooring, machinery, electronics, home appliances, electromechanical, hardware, furniture, rubber and other industries.
