Abstract

The dyeing of wool with reactive dyes in a strongly acid medium (containing sulfuric acid) requires no longer acceptable, long heating-up times (50-60 minutes) in order to obtain level dyeings. It has now been found, according to the invention, that by rapidly heating up the dyebath which contains the dyes of the vinylsulfonyl type and also all the ingredients, except the acid, to the dyeing temperature together with the material to be dyed and then metering in the sulfuric acid under isothermal conditions at the dyeing temperature it is possible to obtain very level and very fast dyeings in a significantly shorter overall dyeing time. Carbonized wool can be dyed without prior neutralization.
