Abstract: In this research, the cotton fabrics were treated with nitrogen plasma for the clinical and anti-bacterial purposes. Turmeric was used a as a natural dye. Some part of both untreated and plasma treated samples was immersed in silver nitrate as a mordant before dyeing. Effect of plasma and silver nitrate on dye ability of cotton samples was compared and studied. Samples were analyzed with different experimental methods, such as scanning electron microscopy (SEM), Reflection spectro-photometry and antibacterial test. Results showed that, turmeric dye have anti-bacterial efficiency and good antibacterial activity achieved by plasma treatment of fabrics. In case of AgNO3 treatment, samples showed 100% antibacterial activity. It also concluded that, nitrogen plasma has synergic effect on antibacterial activity of turmeric as natural dye on cotton fabrics.
