Abstract

PURPOSE: The spinning dope is extruded through the outside nozzles in a spinneret for sheath-core type conjugate fiber and subjected to gel-drawing without contact with the coagulant extruded from the inner nozzle to produce hollow fiber of high quality for ultrafiltration membrane at a high speed.
CONSTITUTION: The spinning dope is extruded through the outside nozzle in a spinneret for sheath-core type conjugate spinning, preferably which has an inner nozzle 1 with the projecting bill more than 2.5mm longer than the outer nozzle 2, and subjected to gel drawing without contact with the coagulant extruded through the inner nozzle to effect high-speed spinning, thus producing the objective fiber.
EFFECT: Even when a coagulant solution of more than 4 coagulation value such as a solution mainly consisting of water is used, high-speed spinning can be effected to give hollow fiber with uniform structure on the wall surface.
