PROBLEM TO BE SOLVED: To enable the multicolor expression of different hues and densities in a polyester fiber. SOLUTION: This conjugated fiber has either of two kinds of polyesters, different in dyeability and arranged in a sheath part and the other arranged in a core part, thick and thin parts in the fiber axial direction and further tangled parts of 3-150 tangles/m in the fiber axial direction. The conjugated fiber is obtained by carrying out the interlacing treatment of an undrawn conjugated fiber yarn having either of the two kinds of polyesters different in dyeability as the sheath component and the other as the core component with air, then performing the semidrawing treatment of the resultant fiber and forming the thick and thin parts in the fiber axial direction. |
