Abstract:
A method for continuously producing sponge bodies (1) made of regenerated cellulose using at least partially agglomerated pore inducers made of sodium sulphate decahydrate is provided. First, a viscose solution is provided. A pore inducer is added to said viscose solution. The viscose solution is laid onto a conveyer belt which is continuously moving. The viscose solution is led through baths on the conveyor belt, resulting in a porous mass made of regenerated cellulose.
