Optimization of Wool Fibers Dyeing with Saffron Petal to Produce Blue Shade

This research is based on to optimize the application of saffron’s petal as a natural dye in wool yarn dyeing process to produce blue shade. Saffron’s petal colorant substance is Anthocyanin, which can be used as natural dyes. Experimental design software was applied to optimize the effective dyeing parameters of wool dyeing such as tin chloride concentration as a mordant (0% to 3%), saffron petals concentration (50% to 200%), dyeing time (30 to 80 minutes) and the final temperature dyeing process (50 to 95 ° C) to get blue shade. In order to this, the color appearance, light and washing fastness of dyed samples was studied at different conditions dyeing. Statistical results of the quadratic polynomial model based on experimental results showed that tin chloride concentration (p
