Textile fiber material is dyed particularly quickly, uniformly, and gently by evacuating it unitl dry in a treatment vat, whereupon the dyeing liquor is introduced into the vat, avoiding any initial condensation in the fibrous material. This is achieved by introducing the dyeing liquor at a low temperature in harmony with the vacuum or by preheating the fibrous material to the necessary degree. After having been introduced, the dyeing liquor is subjected to slight excess pressure and caused to act on the fibrous material which, subsequently, is dried in the vat.
