FIELD: process engineering.
SUBSTANCE: invention relates to gas cleaning. Proposed material comprises two fibrous layers of the mix of polyester fibers of 0.33 and 0.84 tex, and carcass canvas arranged between said layers, the ration of said fibers in said mix making 80-20 wt %. Said layers are bonded together by needling and impregnated by water dispersion base on perfluoronamiloxyrane with solid residue weight gain of 2-6%. One side of filtration material is smooth.
EFFECT: higher filtraiton efficiency.
