Abstract (en)
[origin: EP0226982B1] 1. A process for the level dyeing of wool or of the wool portion of fiber blends by the exhaust dyeing technique by applying an aqueous liquor of dyes which exhaust under strongly acidic conditions to the fiber material at a pH between 2 and 3 with heating, which comprises combining acid dyes which exhaust under strongly acidic conditions and reactive dyes with one another to form trichromatic recipes by replacing acid dyes of inadequate fastness by reactive dyes of the same or similar shade.
