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 of color strength and color parameters of the samples was performed using a reflective spectrophotometer and wash and light fastness were done based on standards. The results show that the fabric was dyed with natural dye of H. Sabdariffa without the presence of mordant are not suitable for the textile industry in terms of color strength and color fastness. Mordanting with different metal mordants and using different dyeing methods can increase the color strength and wash and light fastness and cause excellent wash fastness (grade 5) and very good light fastness (grade 5 to 6). A comparison of dyed samples shows that the change of mordant type in the simultaneous dyeing method has a greater effect on the color properties of the samples than pre- and post-mordanting methods.
