PROBLEM TO BE SOLVED: To provide a polyester-based mixed product for preventing lack of hiding, having flexible feeling and stretchability, and providing nearly uniform color when dyed by reducing difference of dyed colors between a polytrimethylene terephthalate-based fiber and a polyethylene terephthalate-based fiber. SOLUTION: The polyester-based mixed product for preventing the lack of hiding is obtained by mixing the polytrimethylene terephthalate-based fiber with the polyethylene terephthalate-based fiber having a sheath-core structure regulated so that the weight ratio of the sheath to the core may be (30/70)-(70/30), and including the core part having 2-10 wt.% concentration of titanium oxide fine particles and 0.4-2.0 mol% diethylene glycol concentration.
