PROBLEM TO BE SOLVED: To provide a polyester yarn of blended filaments with different shrinkage, providing a stretchable fabric simultaneously having delicate and elegant bulking feeling, natural and dry touch feeling and excellent grandrelle-like feeling. SOLUTION: The polyester yarn of the blended filaments with the different shrinkage is obtained by blending and interlacing a low shrinkage yarn and a high shrinkage yarn which is a multifilament of a polytrimethylene terephthalate. The low shrinkage yarn comprises a polyethylene terephthalate multifilament having thick and thin parts in the fiber axis direction, and a multifilament substantially not having the thick and thin parts in the fiber axis direction, and has 0-6% self extension rate as the whole yarn in a dry-heat treatment (at 180°C) after hot water treatment (at 100°C).
