Abstract

Photo-yellowing is one of the most important drawbacks for wool fabrics. Different methods have been used for decreasing the yellowing rate. One of them is covering the wool surface by ultraviolet absorbers. In this study wool fabric was treated with nano titanium dioxide and butane tetra carboxylic acid, cured and then irradiated for three hours. Yellowness variations of irradiated samples were detected by a spectrophotometer. The result of this study showed that titanium dioxide was a very suitable UV absorber and its effect depends on concentration.
