| Abstract | ||||
| The main task of this study is to establish a one step dyeing of wool/polyester blended fabric using basic dyes. Wide range of parameters has been studied such as pH values, PEG-600 concentration, dyeing technique, fixation time and temperature. The best dyeing conditions were achieved, using different colors of basic dyes at pH 9. The color strength (K/S) values of the dyed blend with temperature increased rapidly the fixation time and temperature until 30 min. at 130˚C.This was followed by a relatively increase in the k/s values by using different amounts of PEG-600. The dyeing technique has an important effect on the k/s values and the improvement can follow the decreasing order of exhaustion under pressure< exhaustion< pad-dry cure method. | ||||
