摘要
The effect of nano SiO2silica and nano TiO2 on the dyeing of cotton fabric with madder dye was studied. The metal nanoparticles were prepared by sol-gel method from respective precursors. Various concentrations of the nanoparticles were added during the dyeing of cotton with madder. The effect of nanoparticles on the color values, fastness, and ultraviolet protection properties was studied. The characterization of the nanoparticles and the dyed fabric was studied using various analytical techniques. The dye was characterized by FTIR and phytochemical analysis. The post dyeing results inferred that there is a considerable improvement in the dye uptake and fastness properties of the dyed fabric after introducing metal nanoparticles. The SEM and EDX analysis confirmed the presence of SiO2 and TiO2nanoparticles on the fabric surface. The physico-mechanical properties of the fabric were found intact after dyeing.
