The invention relates to technology of obtaining thin fiber filtering materials. The method for making filtering material on base of ultra-thin synthetic fiber is in mixing granules of fiber-forming and matrix polymers, with formation of composition film of melt of polymer mix and extraction of matrix polymer from it. To mix of fiber-forming and matrix polymers one additionally includes at stage of mixing in amount of 0.5-5.0% of mass of matrix polymer second fiber-forming polymer that forms block-copolymer with matrix polymer in process of forming of composition film.
