- This research reports a novel and innovative method of developing and optimising nano-emulsions using two combinations of herbal extracts produced from Moringa oleifera, curry leaf, coconut oil (nano-emulsion 1) and other using Aegle marmelos with curry leaf and coconut oil (nano-emulsion 2).
- Researchers identified herbal combination following a systematic review of plant-based antimicrobial substances
- Nano-emulsions were characterised and optimised for their properties (pH, thermal stability, nano-particle size and Whiteness Index)
- Organic cotton fabric (plain woven) – 20 and 60 gsm were selected in this study
- Nano-emulsions were applied on the organic fabric using continuous and batch process
- Finished fabrics were characterised for their surface morphology using scanning electron microscopy, energy dispersive X-ray (EDX) analysis and Fourier transform infrared spectroscopy (FTIR) analysis.
- The finished fabrics were evaluated for their Whiteness Index, assessed for antimicrobial resistance against Gram-positive (Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli) using AATCC 100 and 147 methods.
- In addition, fabrics were assessed for their antifungal efficacy (AATCC 30), tensile strength and air permeability.
- Results suggested that finished organic fabrics with nano-emulsions had antimicrobial resistance, antifungal, wash fastness after 20 washing cycles, and sufficient strength.
- This novel finishing method suggests that organic cotton fabrics treated with nano-emulsions can be used as a durable antimicrobial textile for healthcare and hygiene textiles.
