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.

Highlights

Modern text ile processes have high demand for development of a combined application of crease resistance fin ishing and reactive printing
The e xperimental results, ANOVA for K/S and Dry Crease Recovery Angle (DCRA) are shown in Table 2, 3 and 4 respectively
The interaction graphs forchro ma& fixation conditions and concentration of CR & fixation conditionsdemonstrate that the Econtrol method of fixation at 130°C using the pad-dry-print-fix-wash method provides an efficient system for imparting single step fixation of reactive printing and crease resistance finishing

Summary

Introduction

Modern text ile processes have high demand for development of a combined application of crease resistance fin ishing and reactive printing. A number o f experimental and numerical studies on simultaneous fixation of reactive dyeing and crease resistance finishing have become availab le in recent years. Some studies have reported on combined application of reactive printing and crease resistance finishing that probably due to contradictory application and fixation conditions of both processes, it is difficult to develop an acceptable combination. A nu mber of theoretical and e xperimental studies exist providing detailed informat ion about the effect of process parameters and operating conditions[1-9]. Since the 1950s many researchers [10-15] have attempted to combine reactive dyeing and crease resistance finishing processes into one step to capture the potential time, energy, and other savings associated with the combined process
