Synthesis of Reactive Auxiliaries for Dye Resist Treatment of Wool

Three reactive auxi liaries cont aining s -triazine-based reactive group s were synthesized and the dye resist effects ac hieved on w ool were e valuated. The results obtained indicated that, the dye resist 2 effect achieved wi th t he bifunctional reactive Auxiliary (R ) was exhibited t he highest value. The effect of the dye bath pH, salt concentration, dyeing temperature, dyeing time, conc. of dye and c onc. of auxiliaries were also s tudied. Good fastness properties of the dyed fabric were achieved.
