The present invention relates to a spinning nozzle which is to produce a netlike fiber by extrusion-spinning a raw fiber solution under a condition involving a high temperature and a high pressure. More specifically, the present invention relates to a spinning nozzle for high-pressure extrusion-spinning, wherein the ratio of a long side to a diameter (L/D) of an outlet of the spinning nozzle is greater than or equal to 1.5 and less than or equal to 10. According to the present invention, it is possible to increase material properties including strength and solidity of a thread as well as productivity in comparison to an existing spinning nozzle. |
