Abstract

The purpose of this study is to examine the possibility of anthocyanin pigments of Rubus fruticosus. In order to achieve this purpose, anthocyanin concentration was analyzed by measuring absorbency from anthocyanin 520nm of Rubus fruticosus. Hair dyeing was increased in dye intake(K/S) with increased dyeing temperature(20oC~60oC) and hair color was changed from red to purple. With increased pH, a* value proceeded from +(red) to -(green) or a color meter was reacted to yellow of original bleached hair and In thealkalic status, red brown or red green or a yellow green was shown because of reddish brown deposits and discolored original color ofanthocyanin mordant. It brought about poor dye intake and dyeing or mordanting effects were lost. It suggested that anthocyaninmordants were specially sensitive to pH and dye intake was rapidly decreased with increased pH. For hair dyeing, mordant concentrations should be selected in consideration of the characteristics of mordants(dye intake, lightless, chroma and color). While acidmordants(FeSO4, AlK(SO4)2
