摘要： The invention is a dyeing method of an aliphatic polyester filament comprising dyeing the aliphatic polyester filament with a disperse dye by selecting a dyeing temperature, dyeing pH, and dyeing time in such a way that the weight average molecular weight of the aliphatic polyester filament has a lowering ratio of 20% or less.
The invention is a method for dyeing the aliphatic polyester filament with good reproducibility and level dyeing property while substantially maintaining the molecular weight and the essentially excellent properties of the aliphatic polyester filament, and can provide dyed articles which have high strength, are excellent in level dyeing property and color fastness to light, and have various hues.
