摘要

PROBLEM TO BE SOLVED: To provide a spinning nozzle capable of stably supplying an additive agent or precisely adjusting a supply amount of the additive agent.SOLUTION: A spinning unit of an air jet spinning machine has a spinning nozzle 1 and produces a thread 2 from a fiber composite 3 that is supplied to the spinning nozzle. The spinning nozzle comprises an introduction path 4 for the fiber composite, an inner swirl chamber 5, a thread formation part 6 protruding into the swirl chamber and a lead-out path 7 for the thread produced in the swirl chamber. The spinning unit has an additive feed section 8 to supply an additive agent 9 to the spinning nozzle. The additive feed section includes at least one top flame that is attached to the spinning nozzle. The additive agent supplied from an additive feeding line 14 of the additive feed section is supplied to the spinning nozzle through the top flame.
