Natural dye extracted from Salicornia bigelovii was applied to silk fabrics by dip dyeing process. The dyeing properties and the functionalities of the silk fabrics were determined. Factors affecting the dyeing properties such as dyestuff concentration, temperature, time and pH were studied. The colorimetric parameters L*, a*, b*, and H, V/C values were measured to select the optimal mordanting conditions. The colorfastnesses of the dyed and mordanted fabrics were estimated for practical use; in addition, the antibacterial property, ultraviolet protection properties were evaluated. The dyeabilities of silk increased depending on the increasing dye concentration, dyeing time, and dyeing temperature. And optimum dyeing results were achieved when dyeing with 300% (o.w.f.) of dye concentration at 90℃ for 100 minutes and at pH 3. The dyed silk fabrics without mordants produced yellow (Y) color and showed yellow (Y) or green yellow (GY) colors depending on the mordants type. The light fastness of dyed and Al mordanted silk fabrics were found to be excellent, and the drycleaning and rubbing fastness were good. The dyed silk fabrics showed no antibacterial property, but Al and Cu mordanted silk fabrics showed 99.9% reduction rate. The ultraviolet protection properties of the dyed silk fabric was improved. And the ultraviolet protection properties of mordanted samples showed very good ultraviolet protection properties.
