Recently, bioactive compounds are becoming more and more important with respect to various environmental benefits such as biodegradability, biocompatibility, reduction in pollution, and non-toxic nature, resulting in their increased upsurge in the global market demands. The present study reports a sustainable approach for assessing colorimetric characteristics (K/S and CIEL*a*b*), sun protection, and antioxidant properties of wool fabric dyed with Acacia nilotica, Terminalia arjuna, and Adhatoda vasica natural dyes with emphasis on the use of ferrous sulfate as mordant to develop bioactive fabric for use in biomedical textile sector. The pretreatment with ferrous sulfate significantly modified color parameters and fastness properties. Sun protection properties of dyed wool fabric were determined in terms of Ultraviolet Protection Factor (UPF) and compared to that of undyed wool fabric.
Antioxidant properties of dyed and undyed wool fabric were determined in terms inhibition of peroxidation by 2,2′- diphenyl-1-picrylhydrazyl radical (DPPH) scavenging activity and compared with that of the ascorbic acid used as positive control. This study demonstrates that A. nilotica, T. arjuna, and A. vasica natural dyes can be employed as promising multifunctional agents for the chemical processing of wool materials especially for developing bioactive textile materials and clothing in near future.
