Regenerated cellulose-based cellular material with a long-term resistance to microorganisms, and its preparation

摘要

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.
