    • A method for dyeing a PLA(Poly Lactic Acid) fiber is provided to improve the dyeability, by selecting dyes suitable for the PLA fiber and determining dyeing temperature suitable for the PLA fiber. A PLA fiber is dyed by disperse dyes selected from C.I. Disperse Yellow 42, C.I. Disperse Yellow 86, C.I. Disperse Orange 30, C.I. Disperse Red 54, C.I. Disperse Red 74, C.I. Disperse Blue 56, and C.I. Disperse Blue 374. The maximum dye temperature is a range of 100-110°C when the PLA fiber is dyed by the selected disperse dyes. The pH of a dye bath is controlled within a range of 4-6 when the PLA is dyed by the selected disperse dyes.
