Abstract

PURPOSE: To spin hollow fibers, e.g. polyester or nylon fibers, of circular cross section stably, by means of a spinneret having protrusions satisfying a specific relation at the outer center of arc-shaped slits with recesses toward the central part of the spinneret.
CONSTITUTION: In a spinneret for hollow fibers in which holes are constituted of 2W6, preferably 2W4, arc-shaped slits having recesses toward the center of the spinneret, protrusions satisfying formulas I and II [W (mm) is the slit width; L (mm) is the length of the slits; H (mm) is the height of the protrusions; A (mm) is the width of the protrusions] are provided. The protrusions satisfying the formulas Iand II provide the adhesion of the polymer extruded through the respective slits with certainty, and the width (a) of the gap (I) between the slits permits the sufficient strength of the spinneret simultaneously.
