Silk Textiles Dyeing by Plant-Derived Colorant in the Presence of Chitosan and Shellac

Abstract The research aimed to dye silk satin textiles with a plant-derived colorant in the presence of additives natural origins, such as chitosan and shellac, investigate whether they can satisfactory results. In this study, series mechanical properties (Young modulus, elongation at break, tensile strength), colorfastness following exposure UVC irradiation 6 months storage dyed samples were tested. Colorimetric measurements scanning electron microscopy (SEM) images performed FTIR spectra registered. Results indicated that used had potential Colorant addition shellac more intensely, covering ensured their color stability during while did not particularly affect under influence irradiation. However, pre-treatment low molecular weight improves storage. Both influenced textiles.
