Abstract

PURPOSE: A plurality of polyesters with the specified range in intrinsic viscosity are subjected to conjugate spinning under specific conditions into sheath-core type conjugate fiber, whereby fiber with high processability and pilling resistance is produced at a high speed by stable operations.
CONSTITUTION: (A) A polyester of 0.6W0.7 intrinsic viscosity is used as the sheath part and (B) another polyester of 0.4W0.5 intrinsic viscosity is used as the core part where they are arranged concentrically and taken up at a speed of higher than 2,000, preferably 2,500W6,000m/min. The difference in intrinsic viscosity between components A and B is made less than 0.2 and the volume ratio of the sheath part to the core part is adjusted to 10W30/90W70.
