This preparation relates to a dye composition for dyeing acrylic fibers. 10 wt. pts. acrylonitrile and 2-15 wt. pts. 20-28% ammonia water were mixed and treated or heated or reacted. The 2-10 wt.% pts. concentrates formic and 1-5 wt. pts. triethanolamine were added to this mixture. The composition produced was homogeneously mixed. The mirabilite was added and dissolved completely. This dye composition works effectively even at low temperatures in a relatively short time and has strong dispersion power.
