Abstract

PURPOSE: The title spinneret designed to spin fibers comprising a number of island components strippable into modified cross-section superfine filaments, wherein island steams, divided into a plurality of components, join with the other island components, are covered with sea components, and collected into a fiber.
CONSTITUTION: The polymer A for the island 1 is divided from the hole 4 and jetted to the tops 5 of the pipes 7. The polymer B for the islands 2 is passed through the space 8 to the gaps between the pipes 6 and pipes 7 to join with the polymer A. The composite streams are made to flow through the pipes 7 and 11 and covered with the sea component (polymer C), which is fed from the space 12 to the annular parts between the pipes 11 and holes 13, before the funnel part 14. A plurality of covered streams are collected in the funnel part 14, and extruded through the orifice 15 into a fiber. The multi-component fiber thus obtained consists of the islands 1 and 2 and the sea 3.
