Abstract

PURPOSE: To reduce the difference in quality between the interior and exterior of an extruded fiber, and to improve the spinnability, by making the feed rate of a sea component polymer from near the inner periphery and the center of a spinneret for an island-in-sea type composite fiber controllable.
CONSTITUTION: A molten polymer fed from the inner periphery of the distribution plate 16 is distributed to the part near the inner periphery and the center of the spinneret 1 by the plate 16 on the spinneret assembly comprising a plurality of the circular spinneret plates 1W4 and the spacer 5. The polymer is then fed from the conduits 6 and 19 of the first and the second spinnerets 1 and 2 and then near the inner periphery and the center of the spinneret 2 to the sea component path 9 between the spinnerets 2 and 3 in the spacer 5. A flow control piece 20 is set for controlling the ratio of flows in the inner and the outer conduits 19 and 6, preferably as a member to regulate the path in a part of the conduit 19.
