The main target ofTthis study is to develop an  antibacterial  chitosan  nanocomposite  fabric  among  in  situ   crated   silver  nanoparticles  utilizing   Vitex  leafTextract,  which  i s amedicinal herb. The CNCFs were evaluated using scanning  electron  microscopy  (SEM), Fourier transform infrared (FT-IR) spectroscopy,Xray diffraction (XRD), and antimicrobial testing. Additionally, these CNCFs have excellent antibacterial characteristics. These CNCFs could be used  in medical  applic  ations like surgical aprons, wound cleansing, wound  dressing,  and  hospital  bed  mat erials, as they were manufactured utilising a simple and environmentally acceptable approach.
