<p>A perforated spinneret (1) characterized in that a plurality of spinning hole groups (31), each including a plurality of odd-shaped spinning holes (2) arranged at intervals along a virtual curve (30) such as an arc extending radially outward from the central part of the discharge front (11) of the spinneret while curving clockwise under a state where the discharge front (11) is viewed from the front, are formed in the discharge front (11), and the plurality of spinning hole groups (31) are arranged while spaced apart from each other in the circumferential direction of the spinneret. When this perforated spinneret is used, soft feeling is attained, and a multi-filament twist yarn having sufficient elasticity and a small variation in quality can be produced.</p> |
