[ What is claimed is:] [1.] A process for producing alveolar cellulosic products of the sponge, sponge-cloth type, from cellulose, characterized in that it comprises:at least partially dissolving said cellulose in an intrinsic solvent for cellulose;incorporating an effective quantity of at least one pore-forming agent into the resulting mixture, with mixing; said pore-forming agent(s), which is/are compatible with the cellulose mixture, being capable of generating macro- and micropores when it/they is/are actuated;gelling the homogeneous dough thus obtained;treating said gelled dough under conditions in which the dissolved cellulose precipitates out and the pore-forming agent(s) present are actuated.
