This study aimed to explore the potential of natural colorants from plants in textile dyeing. Different natural dyes extracted from plants were applied on cotton, silk, and polyester yarns with and without mordants, showing enhanced color strength values with the addition of mordants. The fastness properties of the dyed yarns were found to be good, indicating that the plants used could be a promising source of natural colorants.
In the present study, an attempt had been made to explore the potential of natural colourants and its application in the textile industry. Natural colorants extracted from the sepals of Mussaenda hybrid, fruits of Carissa carandas and Syzygium cumini were applied on cotton, silk and polyester yarns accompanied with mordants (Alum, Acetic acid, Copper sulphate and Lemon juice) and without mordant, using an aqueous method. UV-Vis spectra of different natural dyes were determined. Percent absorption, colour co-ordinates values (CIELab), colour strength (K/S) values and fastness properties of the selected dyed yarns were tested. Different shades of yellow, pink and purple were obtained from the aqueous extracts of Mussaenda hybrid, Carissa carandas and Syzygium cumini. K/S values were enhanced with the addition of mordants. Fastness results of the selected dyed yarns showed good grades. The present study demonstrated that the above plants could be a promising source of natural colourants.
