Improvement of the fastness properties of garment leathers with TiO2/SiO2/glymo based nanocomposite solution and lacquer coating

Abstract

In this study, the development of TiO2/SiO2/GLYMO based nanocomposite solution by sol-gel method and the improvement of the fastness properties of the garment leathers by using the nanocomposite on leather in finishing process with lacquer have been investigated. The results show that the films of TiO2/SiO2/GLYMO based nanocomposite solution on the leather samples are homogeneous and even. When the fastness properties of the films were evaluated, it was observed that dry rubbing and wet rubbing fastness, color fastness to water and perspiration of the leather surfaces finished with the nanocomposite were improved and the best results were obtained from the KL group of leathers which was treated with the nanocomposite together with lacquer. In addition, it was proposed that the improvement of color fastness to light and UV light of the TiO2/SiO2/GLYMO based nanocomposite treated leathers was probably resulted from UV-absorbing properties of TiO2. As a result, the application of TiO2/SiO2/GLYMO based nanocomposite solution with lacquer coating on garment leathers improved their fastness and thus garment leathers with longer wear life were obtained in this study.
