Structure of New Filter Material:
The structure diagram of the new filter material is shown above. -The surface filter layer is a dense surface layer composed of fine fibers and ultrafine fibers. -The middle layer is high strength and low elongation base cloth. -The inner layer is a coarse porous layer which is easy for air to pass through. -The design of gradient layered structure enables the filter felt to have high filtration accuracy and maintain a large air permeability.
