Mathematical Modelling can lead to a better understanding of the role of variables
in real dyeing process. The aim of this study was to model colour yield in dyeing
cotton cloth with selected reactive dyes via two phase pad-steam fixation method, as a function of steam temperature, steaming time and alkali concentration. Factorial design was employed and at first. polynomial regression models were produced for the selected monochlorotriazine, dichlorotriazine, trichloropyrimidine and vinylsulphone
reactive dyes. As these models did not meet the necessary requirements, orthogonal
polynomial regression was employed. This led to the acceptable models except in one case. The models for the selected dyes in each group of monochlorotriazine, dichlorotriazine, trichloropyrimidine showed similarity but not for vinylsulphone dyes. Response surfaces of the models can be used to find the optimum conditions that maximize
the colour yield of each dye.
