Polyester needle felts have a high production speed, high labor productivity and low product cost.
The production process is simple, easy to monitor and ensure the stability of product quality.
The three-dimensional structure of the fiber in the needle felt filter is conducive to the formation of a dust layer, and the dust-catching effect is stable. Therefore, the dust-catching efficiency is higher than that of a general fabric filter.
Polyester needled felt dust bag porosity as high as 70% -80%, for the general weaving filter material 1.6-2.0 times, so its own good air permeability, low resistance.
