ABSTRACT:
Fine grain or fibrous solid active particles are immobilized in an areal or flat, flexible stratified body. The active particles serve for treating a liquid or gaseous medium circulating between the stratified body and the surroundings. The treatment, among other things, encompasses the sorption of substances, if desired, followed by desorption for regenerating the active particles, the emission of substances, the ion exchange and the catalysts of chemical reactions. The active substances or particles are enclosed between a base or substratum layer and a fiber-containing cover layer. Both layers are held together by means of holding fibers which are densely distributed over the entire surface and simultaneously anchored in both layers, whereby at the same time there are also immobilized the active particles. According to a preferred method the holding fibers are removed from the cover layer by fiber-orienting needles.
