Reactive Printing and Crease Resistance Finishing of Cotton Fabrics-Effects of Fixation Modes by 2 2 .4 1 Mixed Factorial Design

Abstract

A single step fixation for reactive printing and crease resistance finishing of cotton fabric has been exp lored in this research work using an experimental design technique (DOE).2 2 .4 1 mixed factorial design have been conducted to efficiently identify the act ive set of factors and their interaction. A ll of the three factors namely chro ma, concentration of crease resistant and fixation conditions were found to be significant.The results further show that apart from the influence of individual factors, the said properties of cotton fabric are also reliant on the interaction effect of the significant factors. The influence of individual factors and their interactions on color yield (K/S) and Dry Crease Recovery Angle (DCRA) has been critically examined using software Design Expert 7.0.The results showed that combination of the Econtrol* process at 130˚C without urea has been verified experimentally to be the best selection for the single step fixation of reactive printing and crease resistance finishing for the cotton fabric using the pad-dry-print-fix method. The uncertainty analyses for measurements shows that the predicted values are in good agreement with experimental data and are sufficiently accurate.
