Abstract
PURPOSE: A spinneret, having many spinning holses having a specific length of extruding holes at the bottom thereof, and capable of controlling the flow rate without causing the local uneven denier, and suitable for the wet spinning method, etc.
CONSTITUTION: Spinning holes 1 with introductory holes 3 having a depth gradually increasing from the central part 7 of the arrangement thereof to the outer peripheral part 6 and the length of extruding holes 4 gradually decreasing from the central part 7 of the spinning holes 1 to the outer peripheral part 6 are provided at the bottom of a spinneret 8. A spinning solution is made to flow in a large amount in a part with a low flow resistance, i.e. spinning holes having a shorter length of the extruding holes 4 at the outer peripheral part 6 and in a small amount in the spinning holes at the central part 7 with a high flow resistance. If the solidifying rate of the spinning solution extruded through the extruding holes 4 at the outer peripheral part 6 is high to block the flow, its flow rate approaches that of the central part 7, and there is little difference between them. Thus, the local uneven denier will not occur.
