Effects of Process Parameters on Single Step Fixation of Reactive Printing and Crease Resistance Finishing of Cotton Fabrics using 2³ Factorial Design

摘要

Effects of process parameters on single step fixation for reactive printing and crease resistance finishing of cotton fabric has been investigated in this research work using factorial design. 2~(3) factorial design have been designed and conducted to check the effect of concentration of crease resistant, urea and time-temperature profile of fixation conditions on the single step fixation process of reactive printing and crease resistance finishing. The results from the experiment suggest that two out of three factors were significant, which are concentration of crease resistant and fixation condition. Evaluation of the single step fixation process in comparison to the two-step combination has been made with respect to k/s value and dry crease recovery angle (DCRA) using software Design Expert 7.0. The statistical and graphical analyses of experiment revealed the significant effect of concentration of crease resistant and fixation condition on the response variables of single step fixation process. Furthermore, the models have been tested for adequacy and found that the assumption of normality and independency are not violated. R~(2) values were very high, suggesting that models accounted for most of the variability.
