Method for continuously producing sponge bodies (1) made of regenerated cellulose using at least partially agglomerated pore inducers made of sodium decahydrate, in which at first a viscose solution is provided, the pore inducer is added to said viscose solution, the viscose solution is laid onto a conveyor belt which is continuously moving, wherein the viscose solution is led through baths on the conveyor belt, resulting in a porous mass made of regenerated cellulose.
L'invention porte sur un procédé de fabrication continue de corps spongieux (1) à partir de cellulose régénérée, par utilisation d'agents porogènes, au moins partiellement agglomérés, obtenus à partir de sulfate de sodium décahydraté, procédé suivant lequel on prépare tout d'abord une solution de viscose, on mélange l'agent porogène à cette solution de viscose, on place la solution de viscose sur une bande transporteuse se déplaçant en continu, la solution de viscose se trouvant sur la bande transporteuse étant envoyée dans des bains, ce qui va former une masse poreuse à partir de la cellulose régénérée.
