Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a spinneret for dry-wet spinning having excellent spinning stability in the process of manufacturing a filament yarn which can provide a filament yarn free from thickness unevenness between the filament yarns as well as excellent quality in terms of e.g. strength and elongation.SOLUTION: A spinneret for dry-wet spinning capable of extruding a polymer solution containing a polymer into a gas from a plurality of nozzle apertures comprises: a spinneret surface in which nozzle holes are formed; liquid level lift-up members which are disposed on at least a portion of the spinneret surface and extend from the spinneret surface in a spinning direction of the polymer solution so as to allow the flow of gases or liquids in a direction parallel to the spinneret surface. |
