Abstract
PURPOSE: A cellulose ester solution in an organic solvent is lenearly extruded out of annular slits and simultaneously a specific liquid is introduced inside the hollow part, thus producing hollow fiber with continuously passing hollow part over the whole fiber length.
CONSTITUTION: A solution of a cellulose ester in an organic solvent is extruded out of the spinneret with annular slits, preferably in almost vertical direction. At the same time, tetrahydrofuran and/or dioxane is introduced inside the hollow part of the linear fiber as the core liquid and the fiber is led into the coagulation bath. As the core liquid, tetrahydrofuran is used as it is; however, it may be mixed with other solvent miscible therewith. The process permits high-speed and stable operations and gives hollow fiber with good dialyzing properties.
