Performance Evaluation and Statistical Analysis of Color Parameters for the Modified and Dyed Cotton Fabric

Abstract

In this study, the reactive composite (N-methylolated-PAam-GG) onto cotton fabrics in the presence of a catalyst (i.e., ammonium sulfate and ammonium chloride) had been prepared, and it was fixed with various conditions of time and temperature, and then dyeing these modified cotton fabrics with the madder as a natural dye. Spectral reflectance, color coordinates, and color differences were measured. Then, the Kubelka–Munk equation was used to determine and evaluate the fixation onto dyed modified cotton fabrics and then study the statistically analyzed results using one-way ANOVA. The existing relationships had been detected with the change of both times (3 and 5 min.), temperature (120,140 and 160°C) with two catalysts used (i.e., ammonium sulfate and ammonium chloride) by the conventional method for the assessment of natural dye onto the modified cotton fabrics if a known concentration of the same dye, is available for comparison. We found that the modified cotton fabrics were fixed with ammonium sulfate at 140°C for 5 min. exhibited a higher color fixed with the madder as a natural dye in all color parameters, color coordinates, and color difference.
