Abstract

PURPOSE: To obtain the title fibers having improved hand, dyeability, water absorption, and antistatic properties, by dissolving the sheath part comprising an organic metal sulfonate and a polyoxyalkylene glycol of concentric composite fibers.
CONSTITUTION: Concentric composite fibers comprising the core part of a polyester consisting mainly of repeating units of formula I: (n is an integer 2W6), and the sheath part of a polyoxyalkylene glycol and an organic metal sulfonate of formula II: [R is 3W30C alkyl or 7W40C (alkyl) aryl group; M is alkali (earth) metal] are treated with an aqueous alkaline compound to remove 40W70% of the sheath part. The cross-sectional area of the sheath part is 1W10 times that of the core part.
