Abstract

PURPOSE: To obtain the title composite fibers capable of being eluted free from uneven division in the long direction, by composite spinning of (A) a specific polyester having a high alkali hydrolysis rate as a division component and (B) polyethylene terephthalate as a component to be divided.
CONSTITUTION: Composite spinning of (A) a polyester having an intrinsic viscosity at 25°C ≤ 0.6 (in 0-chlorophenol) consisting of 3 mole % or more of ethylene-5-sodium sulfoisophthalate and 80 mole % or more of ethylene terephthalate as a division component (easily eluted) and (B) polyester consisting of 80 mole % or more of ethylene terephthalate as a component to be divided (slightly eluted) is carried out to give divided composite fibers wherein the component (B) is divided into plural parts by the component (A).
EFFECT: The two components will not peel before the elution, and only the division component is eluted easily by treating with a dilute alkali.
