Needle Punching Nonwoven Fabric

Density of needled filter could be controlled through needle-punching parameters, such as needling density and penetration depth; many needle-punched nonwoven filters are made of multiple layer structures including various needled nonwoven fibrous layers and reinforcement layers (scrim, woven fabric, lightweight spunbond nonwovens, etc.) to achieve required filtration efficiency, compactness, dimension stability, and mechanical robustness.
