Enzymes are now widely used in various textile processes, such as pretreatment and finishing. In the present investigation, undyed as well as vat‐dyed cotton fabrics were pretreated with intracrystalline swelling agents, such as sodium hydroxide and ethylene diamine, and an intercrystalline swelling agent, morpholine. Acid hydrolysis was also carried out on cotton. All the samples were further treated with acid and neutral cellulase enzymes. The effect of pretreatment and enzyme action on the vat dyeing was then studied. In all cases, it was found that intra‐ as well as intercrystalline swelling resulted in enhancing the response of the enzymes.
