Zusammenfassung:	PURPOSE: A dyeing method for wool and ply-yarn of polylactic acid-fiber is provided to prevent degradation of property of wool and polylactic acid-fiber through pre-processing conditions, optimized dyeing conditions, and post-processing conditions etc. CONSTITUTION: A dyeing method for wool and ply-yarn of polylactic acid-fiber includes the following steps of: bonding wool spun yarn and polylactic acid-fiber spun yarn; refining the manufactured ply yarn in a neutral bath containing a polyoxyethylene alkyl ester-based scouring agent and water; dyeing the ply yarn with dissolved liquid; post-processing the dyed ply yarn; processing the ply yarn with a softening agent bath in which a silicon-based softener, CH3COOH and water are mixed; and evaporating moisture from the ply yarn.
