Nowadays, it is impossible to get a job in the labor market especially in the fields of engineering without knowledge and skills. In order to introduce scientific and experimental methods of scouring agent which is one of the most widely used in reactive dyeing for cotton, we tested two important and popular scouring agent in the market Hero + and Hero Grand. On the other hand, for obtaining pleasing scouring to remove any oils and other impurities. the performance of scouring agent by considering usage amount depends on ability to reduce surface tension and increasing wetting time, wettability, removing stains, whiteness index, height of foam and cloudy point. The main purpose of this study is evaluating and comparing scouring agents by introducing standard and experimental methods applicable to all plans.
