Pad Batch Dyeing is a type of semi-continuous dyeing process, which is mainly used in the dyeing of cellulosic fiber like cotton or viscose with reactive dyes. Pad batch dyeing is a textile dyeing process that offers some unique advantages in the form of versatility, simplicity, and flexibility and a substantial reduction in capital investment for equipment. It is primarily a cold method that is the reason why it is sometimes referred to as the cold pad batch dyeing. [3] Special features of pad batch dyeing Significant cost and waste reduction as compared to other conventional dyeing processes. Total elimination of the need for salt and other specialty chemicals. For example there is no need for anti-migrants, levelling agents and fixatives that are necessary in conventional dye baths. Optimum utilisation of dyes that eliminates specialty chemicals cuts down chemical costs and waste loads in the effluent. All this results in a formidable reduction in wastewater treatment costs. Excellent wet fastness properties. Pad batch dyeing cuts energy and water consumption owing to low bath ratio (dye: water) required for the process. This is because unlike other dyeing processes it does not function at high temperatures. A uniform dye quality is achieved with even colour absorbency and colour fastness. As compared to rope dyeing, Pad batch dyeing produces much lower defect levels. In pad batch dyeing, qualities like high shade reliability and repeatability are common. This is because of high reactivity dyes with rapid fixation rate and stability. Lastly Pad batch dyeing can also improve product quality. The fabric undergoing the cold pad batch dyeing process is able to retain a uniformly coloured appearance. It shows added luster and gives a gentle feel. The fabric gives a brighter look in sha
