Irregular-shaped spinning having polymer discharge holes 11 with a star-shaped cross section as shown in Fig. 7 (sometimes a spinneret is manufactured.In short, it is sufficient that the polymer discharge holes have a conformal radial cross section). Accordingly, the discharge electrode in which the polymer discharge holes are formed has a cross section of an equiangular radial shape, such as an X-shaped cross section and a star-shaped cross section.

。As can be seen from the explanation in section 1, the method for producing the irregularly shaped spinneret of the present invention is to perform electrical discharge machining using electrical discharge electrodes with grooves at the proximal end of each side of an equiangular radial cross section, such as the W1 surface. Since a polymer discharge hole with a protruding part is drilled on the inner surface of the proximal corner part of each side in a square radial shape, the machining allowance is small because only the protrusion 44IX is removed by finishing shaping. is extremely small. tj(l) does not take 11.4 hours for finishing shaping as in the conventional method, and 1. The manufacturing efficiency of J-j type spinneret is improved. Since no beams are formed on the inner surface of the proximal end corner of each side of the polymer discharge hole, it is possible to spin a high-quality irregularly shaped yarn without damaging the spun yarn. There are some things you can do.
