  Abstract

Nature has been a first inspiration for the evolution of mankind. Natural colorants of plants origin highly influenced the textile industry and target a wide range of textile functionalities. Tannins from Terminalia chebula fruits have been explored to develop colored, UV protective and antioxidant functional wool textiles. Metallic mordants (Alum, ferrous sulfate, and stannous chloride) under ecological permissible limits are utilized to establish the correlation with the functional properties achieved on textiles. Shades of various colors on wool are characterized in terms of CIEL*a*b* and color strength (K/S) values on Hunter-Lab spectrophotometer. Ultra-violet (UV) protection ability was measured in terms of UV transmittance and UPF (UV protection factor) values. UV transmittance is consistently below 5 % in all dyed wool fabrics, while it was upto more than 30 % in undyed wool. Antioxidant results of both mordanted and unmordanted (control) dyed wool fabrics are found highly appreciable up to 99 % of activity. Multifunctional colored wool textiles are developed with ecofriendly and economically viable process and resources.
