Cotton fibers were coated chemically with silver 
nanoparticles to increase the antibacterial efficacy. Silver 
nanoparticles were synthesized by agreen method and coated on 
cotton fabric using dipprocess using extracted of Ficus Caria and 
Tannic acid. The process includes the activation of cellulose fibres 
in alkaline solution, followed by reduction of silver nitrate to Ag NPs 
in the second stage, while the last stage of process involves 
washing of fibres. In situ preparation of Ag NPs with plant and 
Tannic acid show nanoparticles were about 70 nm in size. The 
synthesized silver nanoparticles were characterized using 
ultraviolet visible spectra, particle size distribution.The treated 
cotton fibers by silver nanaoparticles showed antimicrobial effects 
by killing and/or suppressing growth of a broad spectrum of 
microbes such as Escherichia coli and Staphylococcus aurues 
bacteria.
