Polygoum tinctoria, as a blue pigment, has been known as one of the oldest natural dyes. The natural dye substances largely consist of plant, animal and mineral materials and appear to have a lot of benefits that enable the dyed materials to exhibit their natural colors. It may have a bit of a harmful influence on the human body itself, in comparison with the synthetic substances. Generally, 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, physicochemical characterization of polygoum tinctoria dye substance was investigated, and polygoum tinctoria dyeing was carried out various natural fabrics according to the various dyeing conditions - fermentation temperature, dyeing temperature, dyeing time, and kinds and amounts of alkali. And then the values of K/S according to dyeing conditions were investigated by colorimeter. Also we investigated to dyefastness against the light, wshing, perspiration and friction by KS(Korea Industrial Standard). |
