Needle punched felt types

Careful production, perfect quality, stable performance

The weight deviation of all our products is ±2% that improvement the use of products in process of uneven air permeability and reduce the service life. Needle punched felt production uses double lapping and carding approach that finishes the final product in one single pass. All fiber will enter the feeding equipment, going through processes of scattering, mixing, carding, lapping and re-scattering. Punching will make the layers of fiber and scrim to inter-penetrate, forming semi-finished filter felt. High temperature treatment will then stabilize the shape and size of the felt.
