Abstract: PROBLEM TO BE SOLVED: To provide a nozzle for a chemically synthetic fiber, capable of mixing and processing the fiber stably even in a high overfeeding ratio. SOLUTION: This nozzle for the chemically synthetic fiber has a yarn thread- introducing opening Y, a yarn thread-discharging opening Ye, and a fluid- injecting orifice I positioned between the yarn thread-introducing opening Y and the yarn thread-discharging opening Ye, and is so structured that a fluid from the fluid-injecting orifice I is injected to yarn threads of the chemically synthetic fiber which are introduced from the yarn thread-introducing opening Y and travel, so as to mix the yarn threads with each other, wherein a separator C is located between the yarn thread-introducing opening Y and the fluid- injecting orifice I, so that the introduced yarn threads are separated from each other.
