The conventional dyeing process (pad-dry-pad-steam):-
The dye is applied from the first padder and the fabric is dried. Since many of the dyes could easily undergo migration on drying, salt and an antimigrant may be necessary in the first road bath to achieve uniformly colored fabric. After drying, the fabric is passed through a pad bath containing salt and alkali, and bleeding into the pad bath should be minimal. Then the fabric is steamed and washed of. This method is suitable for dyeing polyester/cotton blend fabric when a thermosol step is introduced between the drying and second padding steps
