PROCESS AND DEVICE FOR PRODUCING CELLULOSE FIBRES

摘要

-9- To prepare cellulose fibres, a solution of cellulose in a tertiary amine-oxi de is shaped in hot condition to give filaments, the filaments are cooled and then introduced into a precipitation bath in order to precipitate the dissolved cellulose, whereby the shaped solution is exposed to an essentially laminar gas stream (Figure 2a) for cooling before introduction into the precipitatio n bath.
