PROBLEM TO BE SOLVED: To obtain a blended article of a polyester fiber and a polytrimethylene terephthalate-based fiber, which provides a dyed material having a soft and flexible hand, excellent color development and solid dyeing properties, slight dispersion by each color of dyeing batch and high color reproducibility and has excellent color fastness to dyeing. SOLUTION: The blended article comprises a polyester fiber that is a polyester obtained by copolymerizing a polyethylene terephthalate with 3-6 wt.% of a polyethylene glycol having 300-2,000 molecular weight and comprising the polyethylene terephthalate composed of≥90 wt.% of ethylene terephthalate repeating unit, has≤1.4 single yarn dtex and a dynamic loss tangent (tanδ) at 110 Hz measured frequency, having a temperature (Tmax) exhibiting the maximum at≥85°C and≤105°C and a polytrimethylene terephthalate-based fiber.
