Abstract

PURPOSE: A copolyester consisting of ethylene terephthalate units and a small amount of ethylene phthalate or ethylene isophthalate units is used as the sheath component to produce the titled conjugate fibers that dye deeply under normal pressure by no use of a carrier.
CONSTITUTION: A polyester containing more than 85mol% of ethylene terephthalate units is used as the core component and a copolyester consisting of more than 75mol% of ethylene terephthalate units and 18W25mol% of ethylene isophthalate and/or ethylene phthalate units is used as the sheath component to produce the objective cojugate fibers. The polyester for the core component has an intrinsic viscosity of higher than 0.5 and the sheath component occupies 20W70% of the total fiber. Further, the core and sheath components are arranged almost concentrically.
EFFECT: The resultant fibers have sufficient strength and thermal stability.
