Dyeing is carried out continuously or discontinuously according to different processes. They all have one problem in common, i.e. that unevenly dyed batches can only be repaired with a great amount of time and cost. Due to the covalent bond between fibre and dyestuff, a levelling-out like with dyeings with direct dyestuffs is impossible. As a rule prior stripping is indispensible in order to repair an unlevel dyeing. Hence unlevelness should be avoided right from the beginning.
