Abstract

PURPOSE: To obtain good cellulosic hollow fibers having uniform and improved dialytic properties, by filling and enclosing the extruded spinning solution in the interior and the outer periphery of the spinning solution which is being extruded through an annular spinning hole with a noncoagulating liquid, and passing the extruded solution through a coagulating liquid.
CONSTITUTION: A copper-ammonia cellulosic spinning solution is extruded through an annular spinning hole, passed through a coagulating liquid, coagulated and regenerated. In the process, a noncoagulating liquid is extruded through an extruding hole 20 provided in the interior of an annular extruding hole 18 for the spinning solution into the interior of the extruded spinning solution, and a noncoagulating liquid is simultaneously extruded through an annular extruding hole 7 provided on the outside of the annular extruding hole 18 to enclose the outer periphery of the extruded spinning solution. The noncoagulating liquid filled into the interior and the noncoagulating liquid enclosing the outer periphery may be the same or different.
