PURPOSE:To manufacture a high-quality multi-filament free from fluffs and end breakage, at a high speed, by extruding viscose dope from a spinneret having a number of spinning nozzles arranged along one circle, into a coagulation liquid flowing in the form of a funnel. CONSTITUTION:A viscose dope is extruded from the spinneret 9 into a coagulation liquid flowing in the form of a funnel, and is coagulated in the course of moving together with the flow of the coagulation liquid. In the above wet spinning process, a spinneret having a number of spinning nozzles 3 arranged in one circle 2 is used as the spinneret 9. The minimum distance between the nozzles is preferably <=2mm..
