Characterization of Wild Turmeric and Holy Basil Combination Herbal Extracts and Their Synergistic Effect on the Antibacterial Properties of Knitted Fabrics

Abstract

In this work, the characterization of combination herbal extracts of wild turmeric (WT) and holy basil (HB) and their synergistic effect on the antibacterial properties of finished single jersey knitted fabrics of cotton, lyocell and micro-denier polyester were analyzed. The main objective of this work is to find out the influence of combination herbal extract proportion, type of material and their interactive effect on the antibacterial properties. The quantitative antibacterial test (AATCC 100) results of the combination herbal extracts-treated single jersey knitted fabrics show that the 50%WT: 50%HB proportion showed consistent bacterial reduction performance against both Staphylococcus aureus and Escherichia coli bacterial strains in all the materials as supported from the test results of phytochemical screening, Minimum Inhibitory Concentration, Fractional Inhibitory Concentration index for synergy, Antioxidant, Cytotoxicity and GC-MS analysis. In terms of material, lyocell and micro-denier polyester fabrics showed good results in 12 hr and 24 hr contact time against S. aureus. Against E. coli, cotton and micro-denier polyester showed good results in 12 hr and 24 hr contact time, respectively.
