Abstract

The present invention relates to a regenerated cellulose-based cellular material with a long-term resistance to microorganisms—bacteria and/or fungi—and to a process for its preparation. Said material, which is of the sponge or sponge-cloth type, contains in its cellulosic bulk an effective amount of 2,4,4′-trichloro-2′-hydroxydiphenyl ether (triclosan) which is distributed and not enclosed in a matrix. At least one latex and advantageously at least one cationic compound are used together with said triclosan.
