Natural dyes 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, we prepared single phase natural indigo from polygoum tinctoria. And then, its physicochemical properties were investigated by DLS, AFM, and SEM. Furthermore, antibacterial activity and cytotoxicity of single phase natural indigo were investigated by agar diffusion and MTT-assay, respectively. Also, polygoum tinctoria dyeing was carried out against fabric according to the various dyeing conditions. And then the values of K/S according to dyeing conditions were investigated by colorimeter. |
