PROBLEM TO BE SOLVED: To provide a dyed product comprising dyed polytrimethylene terephthalate-based fibers, having high sublimation fastness and clearness, and to provide a method for producing the dyed product. SOLUTION: The dyed product comprises the dyed polytrimethylene terephthalate-based fibers, wherein trimethylene terephthalate dimer accounts for 0.1-1.5 mass% of the polytrimethylene terephthalate-based fibers. The dyed product is produced by dyeing the polytrimethylene terephthalate fibers using a disperse dye and a treatment agent comprising an ester compound of a polyhydric alcohol alkylene oxide adduct and an alkyl- or alkenylfatty acid.
