Process for the preparation of formed bodies of regenerated cellulose from solutions of cellulose derivatives in dimethylsulphoxide

摘要

A process for the preparation of formed bodies of regenerated cellulose from cellulose derivative solutions in dimethylsulphoxide is disclosed. The solution is extruded and coagulated in a coagulating bath which is a saline acqueous solution having a substantially non-alkaline or preferably a substantially neutral reaction, a formed body being thus produced.
