Abstract

PURPOSE: Two kinds of polyester different in intrinsic viscosity is conjugate spun through a spinneret with T-shaped nozzles into side-by-side conjugate fiber, thus producing the titled fiber with high crimping, bulkiness and good luster.
CONSTITUTION: Two kinds of polyester with 0.09W0.26 difference in intrinsic viscosity is melt-spun through a spinneret having T-shaped nozzles which satisfy equationsI, II and III (LA is the slit length of the upper horizontal slit; WA is the width of the upper horizontal slit; LB is the slit length of the lower vertical slit and WB is the width of the lower vertical slit) into side-by-side type conjugae fiber with more than 0.46 intrinsic viscosity, thus producing the objective fiber.
