Using Chitosan for Improving the Dyeability of Cotton Fabrics with

The study examined the influence of chitosan to improve dye absorption on cotton farbric using Mangosteen Rind. The results of this study concluded that the cotton fabrics treated with chitosan had better depth of shade than those of the untreated fabrics dyed with Mangosteen Rind. This may be because the chitosan treated cotton fabrics provided more dye sites than those present on the untreated fabric. The cotton fabrics treated with chitosan not only provided better depth of shade but also provided better wash fastness and light fastness than those of the untreated fabrics when dyed with Mangosteen Rind. The use of different mordants and mordanting methods affected the dye shade and depth of shade differently on the dyed fabrics both with and without chitosan. Only natural dyes can have their shades changed by using different mordants. This phenomenon cannot be observed in synthetic dyes. The cotton fabrics dyed with mordants had better wash fastness and light fastness than those of cotton fabrics dyed without mordant
