Evaluation of the Effect of Mordant Types and Dyeing Methods on the Color Properties of Viscose Lycra Fabric Dyed with Hibiscus Sabdariffa Calyces
In this study, the dyeing with Hibiscus sabdariffa extract in the presence of metal mordants was studied.In order to evaluate the effect of the dyeing method on the color parameters of the samples, three premordanting, simultaneous and after-mordanting methods were used using iron sulfate, copper sulfate,aluminum potassium sulfate, zinc chloride and citric acid as mordant materials in dyeing. Evaluation ofcolor strength and color parameters of the samples was performed using a reflective spectrophotometerand wash and light fastness were done based on standards. The results show that the fabric was dyed withnatural dye of H. Sabdariffa without the presence of mordant are not suitable for the textile industry interms of color strength and color fastness. Mordanting with different metal mordants and using differentdyeing methods can increase the color strength and wash and light fastness and cause excellent washfastness (grade 5) and very good light fastness (grade 5 to 6). A comparison of dyed samples shows thatthe change of mordant type in the simultaneous dyeing method has a greater effect on the color propertiesof the samples than pre- and post-mordanting methods.
