This article studies the complete reuse of reactive dyebaths. Because of the hydrolysis of residual reactive dyes due to the fixation conditions and because of relatively large amounts of dyes and salts left in the effluent, reusing hydrolyzed reactive dyes is a challenge to dyers. Seven reactive dyes, C.I. Reactive Red 120, Black 5, Blue 5, Violet 5, Orange 13 and 16, and Yellow 2, and two fabrics, nylon 6, 6, and wool, were examined. It is shown that when using suitable dyeing conditions, hydrolyzed reactive dyebaths could be reused for nylon and wool dyeing with very good wash and crocking colorfastness.
