In this paper, we select pure PET and PET mixed Lycra ' Nylon and Nylon mixed Lycra as the dyed fabrics, dyestuffs are the disperse dye ' acid dye. The dyeing method is one- bath-two-section impregnation and the quality characteristic is E (KJS values) of the fabrics. Our purpose is to find the optimum combination of processing parameters to achieve the customers' demands. Taguchi experimental design method has been proposed in the research. In view of the dyeing results, the parameters including machine operating temperature, dyeing time, dye liquor concentration, and bath-ratio value are regarded as the control factors. The L9(34)
orthogonal array together with the ANOVA approach are employed to determine the optimum conditions, significant factors, and percent contribution. In the experiments, KfS values of fabrics are chosen to be the smaller-the-better target characteristic, and the confirmation experiments are performed and verified the reproducibility of the experimentation. The K/S values of dyed fabrics in optimum condition are much closer to the target values.
Keywords: Dyeing, E, Taguchi Experimental Design Method, ANOVAApproach, Confirmation Experiments
