Textile industry is an industry related to individual hygiene at any age and social group . Nanotechnology is a most promising field for generating new applications in medicine. However, only few nanoproducts are currently in use for medical purposes.A most prominent nanoproduct is nanosilver. Nanosilver particles are generally smaller than 100 nm and contain 20–15,000 silver atoms.Nano-Silver is one of the applicable products in Nano-technology that is popular for its anti-bacterial property and as a catalyst can destroy more then 650 kinds of virus, bacteria and mushroom. Nano-silver with this property when comes in contact with skin causes sensitiveness. Nano-Silver in comparison with other anti-bacterial methods (like using chemical material in finishing products), has high strength and efficiency and using it is easily possible in particular process.In this experimental research samples from cotton knitted fabric of Rib 1 X 1 under various condition (temperature, time, concentration, and bath) is anti-bacterial by dipping method. Then different samples with dimension 2 X 2 in micro sup anion environment is incubated vertically (temperature 37oC, time 48 hours). Finally, amount of anti-bacterial of fabric that the samples at boiling temperature, time 10 minutes and concentration 200ppm, also temperature of 75oC, time 45 minutes and concentration 200ppm shows the maximum amount of anti-bacteria.
