The effluent from textile dyeing industry have negative impact on environment pollution. Most of the industry use reactive dye and this dye produce effluent after dyeing. In this work, the dye bath of reactive dyeing used again without draining them. 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. Two reactive dyes are Reactive Red & Reactive Yellow and Two materials: Nylon, Silk as well as Silk fiber & Nylon Yarn, were examined. It is shown that when using suitable dyeing conditions such that by controlling pH and temperature hydrolyzed reactive dye baths could be reused for silk and nylon dyeing with very good wash and moderate colorfastness.
