PROBLEM TO BE SOLVED: To provide a method for stably spinning high quality triacetate fiber for a long time without reduction of dye-affinity by improving releasing performance of the triacetate from a spinning nozzle in spinning allowing suppression of adhesion of spinning dope to the spinneret, and accumulation of a deterioration product. SOLUTION: The invention relates to the method for spinning triacetate fiber comprising use of a silicone oil which is soluble in methylene chloride. The method solves defects that in long time spinning, spinning dope discharged from the spinneret adheres on the surface of the spinneret and a part of a discharging nozzle and deteriorates to cause variation of dyeing quality and thread breakage.
