Abstract

The invention relates to a process for the continuous dyeing of textile webs of synthetic fibres or mostly synthetic fibre materials with suitable dyestuffs and dyestuff fixation according to a usual method, wherein the padding operation of the fibrous material with an aqueous dyebath having a relatively high concentration and squeezing off the excess of liquid is effected while pressing from both sides endless webs of an absorbent fibre material (auxiliary webs) onto the material to be dyed.
