PURPOSE:To obtain the titled filament showing high luster characteristics and high stretchability, by making the sectional outer shape of conjugated filament concentrically placing two thermoplastic polymers having different shrinkage percentages into a triphyllous shape. CONSTITUTION:The sectional shape of filament is made into a triphyllous shape and the deformation degree is 1.2-1.8, preferably 1.35-1.55. The conjugated interface at the sectional central part of the fiber of polymers A and B is substantially in parallel with one side between two leaves of sectional outer shape of fiber, a trapezoidal part at the single side from the central conjugated interface consists of the low-shrinkable polymer B and the other triangular part is made mainly of the high-shrinkable polymer A.
