Polyester (PET) regular needle felt 

with smooth surface, needle felts made from polyester yarns have good air permeability and are not yielding. They are excellent in industrial fume dust-controlled and dust collection. 

The weights are available from 250G/M2 to 1100G/M2. 

Polypropylene (PP) needle felt 

Benefits from the good physical and chemical characteristics of polypropylene, the PP felts are wearable, acid & alkali resistant and have good air permeability. So they are usually used in the strong acid and alkali conditions 

Besides the dust collection application, PP needle felts are also used in the liquid filtration processes 

We also provide filter bags made in this felt.
