Abstract

PURPOSE: Special composite filament yarns with a change in the long direction, comprising sheath and core components of specific shapes, wherein part of the core components are exposed to the surface in the long direction.
CONSTITUTION: Sheath-core type composite filament yarns comprising sheath and core components consisting of two types of polymers having a small affinity for each other, e.g. a polyamide and a polyester. The core components are of cross- sectional shapes with at least three protrusions arranged in the symmetry of rotation, and the tips of the protrusions are partly and intermittently exposed to the filament surfaces in the long direction by mechanical treatment, e.g. draw falsetwisting, or chemical treatment with a solvent. The peeled split parts may be napped or dyed in different colors.
