PROBLEM TO BE SOLVED: To provide a polyester combined filament yarn dyeable in a deep to a medium color at a low temperature of≤100°C and having high elastic modulus. SOLUTION: The core-sheath type conjugated combined filament yarn comprising a highly shrinkable polyester filament yarn A as a core part and a low shrinkable low-temperature dyeable polyester filament yarn B as a sheath part is prepared. For further detail, the core-sheath conjugated combined filament yarn in which the shrinkable polyester filament yarn A is present in the core part and the low-temperature dyeable polyester filament yarn B is present in the sheath part can be obtained by interlacing both the polyester filament yarns and then shrinking the interlaced filament yarns in boiling water.
