Abstract

For eco-friendly antibacterial finish, based on the literature survey ten herbs were selected to finish 100% cotton, 100% bamboo and 50:50 bamboo/cotton single jersey knitted fabrics, for sportswear. The selected herbs were shade dried and ground into fine powder, using methanol, herbal extracts were prepared. Dip dry method has been carried out to finish the selected fabrics with herbal extracts for antibacterial finish. Evaluation of antibacterial finished fabrics were carried out by ENISO 20645 test method, based on the results three herbs namely Azadirachtra indica (Neem), Leucas aspera (Thumbai), Acalypha indica (Kuppaimani) were selected for further study. Microcapsules were developed for the three selected herbs and applied on the selected fabrics using Exhaust method. Microencapsulated antibacterial finished fabrics were assessed by AATCC 100-2004 test method to select best one herb among three. Among all samples, Azadirachtra indica (Neem) finished fabrics shows higher percentage of bacterial reduction. Hence, it was selected for further study. Optimization of concentration for Azadirachtra indica (Neem) extract at 4%, 6% and 8% has been carried out. Among all the samples, Azadirachtra indica (Neem) finished at 6% concentration shows higher percentage of bacterial reduction. Hence, 6% of Azadirachtra indica (Neem) was selected for antibacterial finishing.
