Antibacterial efficacy analysis of Punica granatum L. leaf, rind and Terminalia chebula fruit extract treated cotton fabric against five most common human pathogenic bacteria

Abstract

Bacterial resistance of textile material is one of the major problems faced in the field of Healthcare and hygiene textiles. Hence, in this study the water and methanol extracts of Punica granatum L leaf, rind and Terminalia chebula fruits were obtained and treated on the cotton plain woven fabric. The fabrics were tested for its antibacterial activity against bacterial strains like Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Proteus vulgaris, and Salmonella typhi. The result indicates that the treated cotton fabric shows a clear microbial resistance with 27-38 mm zone of inhibition in the agar diffusion test against all the above mentioned strains. Similarly, to measure the microbe resistance quantitatively, the AATCC Test Method 100-2004 was performed. The result indicates that, the treated samples show 99% of reduction against Staphylococcus aureus and 90% reduction against Escherichia coli. Further the treated cotton fabrics performance was evaluated using AATCC Test Method 61-2003 for wash durability.
