The leaves and branches of were extracted with distilled water and 30% ethanol, and the dyeability and functionality of silk fabrics were examined according to the color characteristics of the extract and dyeing conditions. As a result of analyzing the ultraviolet and visible light absorption spectrum of the extract, it was possible to confirm the peak of flavonoid belonging to polyphenol, and the peak of riboflavin expressing yellow color was confirmed. Adsorption equilibrium was observed at 4% dyeing concentration and 60 minutes of dyeing time, and as the temperature increased, dyeing amount increased without color change of Y-series. Aluminum mordanting also increased the yellow color. The color fastness of washing and UV irradiation was low, but the color fastness of rubbing was evaluated as relatively good. The silk fabric dyed with the distilled water extract of the leaves showed a 99.9% bacteriostatic reduction against Staphylococcus aureus and Klebsiella pneumoniae, showing excellent antibacterial properties.
