PROBLEM TO BE SOLVED: To provide a polyester combined filament yarn of different shrinkage producing an excellent spunlike touch in a stretchable fabric. SOLUTION: The polyester combined filament yarn of the different shrinkage is obtained by carrying out a filament combining and interlacing treatment of a low shrinkable yarn composed of a polyethylene terephthalate multifilament yarn having thick and thin unevenness in the fiber axis direction and >0 to 6% self elongation percentage by dry heat (180°C) treatment after hot water (100°C) treatment with a highly shrinkable yarn composed of a polytrimethylene terephthalate multifilament yarn.
