The natural dyes have moderate colors and are environmentally friendly, while harmful mordants must be used for fixing them and obtaining a full color range on fabrics and it is very hard to improve K/S of the dyeing and mordanting. In this study, polygonum tinctroium dye with nano size morphology was prepared using the dorr agitator, homogenizer, and lyophilization and investigated physicochemical characterization. Then, it's dyeing was carried out various fabrics according to the various dyeing conditions and the values of K/S according to dyeing conditions were investigated by colorimeter. Also we investigated to dye fastness, cytotoxicity, and antibacterial activity. |
