COMPOSITE SPINNERET, CONJUGATED FIBER, AND PROCESS FOR MANUFACTURING CONJUGATED FIBER

WIPO Patent Application WO/2014/077359

A1

The present invention addresses the problem of providing: a conjugated fiber having a sea-island structure such that the sea polymer of the sea-island structure can be easily eluted even when the island component is present at a high density; and a spinneret suitable for manufacturing the conjugated fiber. This conjugated fiber has sea-island regions (42) and a sea component region (44), wherein the sea component region (44) lies among the sea-island regions (42), and has a width which is equal to or larger than a prescribed level. This composite spinneret has a discharge plate which has an extrusion hole assembly that is composed of both a group of sea extrusion holes for forming the sea component region and a group of sea-island extrusion holes.
