Improvement in dyeing behavior of the wool fabrics using nanosilver pretreatment

Nanotechnology, a rapid-growing branch of science, is widespread in ample areas of life around the world. One of the most common examples of nanocompounds is nanosilver, which is carried out frequently in medicine, electronics, the construction industry and chemical technology, mostly as an exceptionally efficient antibacterial and antifungal agent. In the recent study, three different anionic dyes were used in order to assess the dyeing behavior of pretreated wool fabrics using different nanosilver concentrations. Moreover, wash and light fastness were determined for these pretreated wool fabrics in order to analyze the effect of the nanosilver on these fabrics. Increase in nanosilver concentration was followed by improvement in dye absorption, as well as, shift in maximum absorption wavelength. In addition, it is noticed that increase in nanosilver concentration results enhancement in the wash and the light fastness. Finally, the optimum nanosilver concentration was measured and the results were reported.
