Substitute products for urea in application of reactive dyes to cotton fabrics
Geeta N Sheth & Aparna A Musale
Caprolactam, PEG 400 and PEG 600 have been identified as partial or complete substitutes of urea in the dyeing and printing of reactive dyes on cotton fabrics. It is observed that the caprolactam in many reactive dyes can replace urea while PEG 400 and PEG 600 are effective for replacement to the extent of about 50% of the optimum concentration of urea required for fixation.
