This study presents an environmentally benign bioactive dyeing and finishing of bio-mordanting cotton fabric via hematoxylin dye extracted from Haematoxylum Campechianum L. medicinal tree. A facile approach to fabricate bio-mordanting cotton fabrics based on gelatin and aloe vera for sustainable green dyeing with hematoxylin dye to achieve a wide range of functional properties and environmental benefits was explored. Optimization of dyeing conditions in terms of salt concentration and pH was

... ducted. Also, build-up properties and fastness characterization has were studied in the presence and absence of biomordants. The natural functional groups of the dye extract were investigated by FTIR spectral analysis. The results reflect the success of bio-mordant chemical modification and mechanism for dyeing process in the course of increasing K/S values associated with improving colorfastness to washing and light as compared to unmordant fabric. All the dyed bio-mordanting fabrics in this work showed great potential value-adding applications in terms of excellent UV protection, antioxidant activity, and high antibacterial activity. The outcomes of this study deal to have implications to the eco-textile green dyeing for the achievement of healthy and sustainable environment applications.
