Abstract― The purpose of this research was to investigate the color characteristic and the dyeing properties of Glycyrrhizae Radix extract on cotton fabrics. The highest absorbance of Glycyrrhizae Radix extract was obtained in 75 v/v% of ethyl alcohol in water. Pre-mordanted cotton fabrics dyed at 30℃ and pH 3 for 80 minutes showed the highest K/S value. According to the dyeing conditions, the colors of the fabrics varied from yellow(Y) and yellowish red(YR) to greenish yellow(GY). The color fastness of the fabrics in dry-cleaning and water was 4~5 rating. The deodorization capacity and UV-cut effect of the dyed fabrics were higher than those of undyed ones.
