Microbial activity causes serious damage to living as well as non-living organisms. Many textile manufacturers are trying to provide better protection to their consumers against microbes and bacteria. Antibacterial finishing treatment is one of the latest achievements in this industry. There is a need to make use of natural herbs and plants rather than synthetic materials over the surface of fabrics to provide protection against certain physical, biological and chemical hazards. This study aimed at developing a textile finish by using leaves of natural plant named Ocimum tenuiflorum (tulsi). The effectiveness of developed finish was determined against its antimicrobial activity with Staphylococcus aureu and Escherchia coli on cotton, polyester, bamboo and a blend of polyester and cotton. The study was experimental in nature. Control and experimental groups of collected fabrics were formulated, where only experimental group was treated with the developed finish. Treated fabrics depicted their zone of inhibition from 35mm to 56mm and 28mm to 52mm for gram positive and gram negative bacteria respectively. It shows better protection against the growth of Staphylococcus aureus and Escherchia coli. Four mechanical characteristics such as tear strength, tensile strength, elongation and stiffness were evaluated to see the difference between treated and untreated fabrics to judge the efficiency of developed finish. The collected data was analyzed through One way Analysis of Variance (ANOVA). P-value less than 0.05 suggest that there is a significant difference between experimental and control groups for their tested mechanical characteristics. It was observed that finish encapsulated the fiber structure completely and provided satisfactory protection against bacterial activity. Moreover, tested mechanical characteristics were also improved with the application of finish.
