초록

Fabric made of 100% silk was dyed with Undaria pinnatifida extracts under differentconditions such as varing colorant concentration, temperature, time and dyebath pH. Thedye uptake (K/S, value), CIE L*,a*,b* and Munsell values of the dyed samples andmordanted samples were measured. Colorfastness, antibacterial property and UV protectionproperty were also evaluated. As colorants concentration increased, the dye uptakeincreased progressively and maximum color strength was obtained at 100% V/V. Dyeuptake also increased with increasing temperature and time, and the maximum colorstrength was obtained at 80℃ and 60min.·With pre-mordanting, the color of the Al and Femordanted silk fabrics was yellow on the Munsell color system, while the Cu mordantedfabric was a greenish color. Al and Fe post-mordanted fabrics had a yellow tone, and theCu post-mordanted fabric had a yellow greenish tone. The light fastness property of theCu mordanted silk fabric was relatively good, The effect of Al and Fe mordanting onfastness was insignificant. The antibacterial activity of dyed and unmordanted silk fabricwas excellent, whereas fabric dyed and mordanted with Undaria pinnatifida extractdemonstrated superior ultraviolet protection.
