FABRIC TREATMENT WITH BIOSYNTHETIC SILVER NANO PARTICLES USING PLANT EXTRACT

Cotton fabric was treated with green synthesized Silver Nano Particles (AgNPs) using a mixture of Neem, Mango and Tulasi extract as a reducing agent in the batch method. Chemical reduction methods were followed for Nano particles formation by adding the extract to Silver nitrate solution in drops. The liquid was then applied to enzymatic pretreated fabric using padding mangle. Both liquid and fabrics samples are characterized using Particle Analyzer (DLS), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and UV-Spectrophotometer. Average Particle size found 98nm and Zeta Potential was -45 to 55(mV). The purity and crystalline nature of AgNPs were confirmed based on the XRD assessment. In addition, specific functional groups, which led to silver nitrate reduction in AgNP formation, were examined using FTIR. Antibacterial activity assays with Gram Positive and Gram negative demonstrated that AgNPs reduced bacterial growth and produced well-defined inhibition zones.
