PROBLEM TO BE SOLVED: To provide a mixture of polyester fiber and cellulosic fiber, having specifically soft and flexible feeling, excellent in color development, having good homochromatic property, hardly causing color variance between batches, obtainable of colored products excellent in color reproducibility and excellent in dye color fastness performance. SOLUTION: The mixture of polyester fiber and cellulosic fiber comprises a polyester fiber comprising a polyester, which polyester comprises polyethylene terephthalate obtained by copolymerization with 3-6 wt.% polyethylene glycol having 300-2,000 molecular weight,≥90 wt.% of which polyester comprises polyethylene terephthalate recurring unit, and which polyester has≤1.4 single fiber dtex and≥85°C but≤105°C temperature (Tmax) exhibiting maximum dynamic loss tangent (tanδ) at 110 Hz measuring frequency.
