PURPOSE: A dyeing method of synthetic filament is characterized by streaming the filament at 130deg.C and breaking fibroin and polyamide type inherent ingredients in a steaming and heating process. The dyeing method thereof is capable of preventing shrinkage, coloring the filament with dyes effectively, increasing dyeing effects and increasing quality of the filament. CONSTITUTION: A dyeing method of synthetic filament is as follows: (a winding process, 100) winding the filament around a soft winder; (a dyes spraying process, 200) spraying dyes on the filament; and then (a steaming and heating process, 300) steaming the dyed filament at 130deg.C..
