Abstract

Method of manufacturing felt-like filter material for purifying liquids, particularly water, characterized by the provision of a coarse non-woven coarse fiber fabric, the pores of which are covered with a network of fine fibers and in which are lodged materials high specific surface area up to maximum, placing on the surface of the fibers and/or materials of high specific surface up to maximum bactericidal or bacteriostatic substances in an insoluble form in the liquid to be purified, particularly in water.
