Abstract
The dyeability and light fastness of natural dye (Tea polyphenols) in the presence of various percentages of Poly-N-Vinyl-2-Pyrrolidone (PVP), ZnO nanoparticles and PVP/ZnO nanocomposites were carried out in this article. These pretreatment agents were padded on functionalized silk fabrics and the modification effects were characterized by Fourier transform infrared spectroscopy and Scanning electron microscope. The dyeability, UV protection and light fastness properties were analyzed respectively. Experimental verification and theoretical analysis of silk dyeing and finishing performance with modified natural tea polyphenols dye were made.
