A dyeing method of polyester filament yarn is provided to produce filament yarn of a straight state by dyeing the filament yarn of a crimp state in a dyeing bath after winding the filament yarn to a bobbin. A dyeing method of polyester filament yarn includes the following steps of: adding heat of the temperature of 140~150°C on filament fabric; dismantling the heat applied filament yarn fabric; winding the filament yarn of a disassembled crimp state to a bobbin; and dyeing the winded filament yarn by dipping the filament yarn in a dyeing bath in which salt brine is stored in the temperature of 130~140°C. |
