Batch dyeing (exhaust dyeing) is a method of dyeing a textile material. The method involves the gradual transfer of dye from a dye bath to the textile material in the same piece of equipment. [ 1 ] The various methods of batch dyeing result from the type of machine used in the dyeing process.
The textile industry is a water-intensive industry that significantly strains the world's water supply. [11] In exhaust dyeing, the ratio of textile to liquor has the most effect on how much water is used. If the liquor ratio is changed from 1:10 to 1:8, 20% less water is used and 15% less money is spent on processing.

Chemical resist dyeing is a modern textile printing method, commonly achieved using two different classes of fiber reactive dyes, one of which must be of the vinyl sulfone type. A chemical-resisting agent is combined with dye Type A, and printed using the screenprint method and allowed to dry.
Printing is the process of adding localized or patterned color to fabrics. [2] Discharge printing involves dyeing first with dischargeable dyes; subsequently, the dyed fabric undergoes a printing process involving the application of a chemical-infused paste that effectively removes the color imparted by the dye.
