PURPOSE: Provided are a dyeing method of polytrimethylene terephthalate(PTT) fiber using a carrier containing natural terpene which doesn't pollute environment, doesn't generate an offensive odor and harmful steam and is capable of dyeing deep color, and the polytrimethylene terephthalate fiber having good fastness. CONSTITUTION: The PTT fiber is dyed by using the carrier containing the natural terpene. Terpene has monoterpene structure or diterpene structure. Monoterpene has monocyclic structure or dicyclic structure. The carrier is mixed with an emulsifier, a dispersant and the terpene ingredient modified with water soluble derivatives. Dyeing conditions are as follows: using 1-20wt.% of the carrier based on the fiber; having 1:5-1:50 of bath ratio; and dyeing at 80-120deg.C for 20-80minutes. |
