Pad-steam dyeing process
The dye, alkali and salt are fed into the pad bath. Dye hydrolysis should not pose a problem if the dye and alkali are continuously fed in to the pad from separate feed tanks. However, the salt concentration may cause dye solubility problems. This process was developed so the intermediate costly drying step could be elimiuted. The main application of this systemis for fabrics that experience migration problems during the intermediate drying step. This method is used for towel and pile fabrics where the cost and difficulty fo drying dyed good is prohibitive. Dyes of high reacivity are preferred
