Abstract:

In order to sustain the natural dyes, there is increased need to identify sources of natural dyes having high yield, good colour fastness and multifunctional properties. In this study, the dyeing potential of natural dyes extracted from locally available plants namely Glycyrrhiza glabra and Lagerstoermia speciosa will be evaluated on the basis of their antimicrobial activity and ultraviolet protection factor. The solutions of both the natural dyes were subjected to antibacterial testing against common human pathogens S. aureus and E. coli. These dyes were applied on wool fabric using standard conditions. The antibacterial activity, colour strength (k/s), UPF and fastness properties of both the dyed samples were assessed. The characterization of dye was done on the basis of FTIR and phytochemical analysis. The results demonstrate that both the natural dyes possess good antimicrobial activity against human pathogens and exhibits good UPF, colour fastness properties as well as colour strength. This study envisages the development of sustainable dyeing technique for wool fabric and also a potential alternative for providing antimicrobial finishing to the fabric.
