| 摘要 |
The present invention relates to a process for preparing synthetic hair fiber comprising halogen-containing synthetic fiber, in which synthetic hair fiber can be evenly dyed at a low temperature in a short period, maintaining excellent fastness, without abnormal shrinking (frizzing) and embrittlement of the fiber due to swelling. The object is attained by dipping the synthetic hair fiber bundle in a solution containing a dye, a carrier (accelerating agent) and a solvent for halogen-containing fiber, and then dyeing at 60 DEG to 90 DEG C.
