ABSTRACT

Dyeing properties of Glycyrrhizae Radix was investigated with silk fabrics. Dyeing water is a type of chalcone, it showed yellow in IR spectrum. K/S value showed high in following conditions; Glycyrrhizae Radix 200g/1ℓ water, 80℃ of dyeing temperature, 90 minute of dyeing time. Glycyrrhizae Radix dyeing water has higher K/S value in alkalinity(pH9) than in neutrality(pH7) or acidity(pH3) conditions. K/S value showed highest in pH5 premordant method of alkalinity dyeing water condition. The color of silk fabric dyed with Glycyrrhizae Radix is yellow. The change of color did not show by mordant treatment. K/S value showed higher in mordant treatment than nonmordant. Light fastness showed over 3 degree in nonmordant, premordant, simmordant(Al,Cu,Fe) and postmordant(Cu). Water fastness showed over 3 degree in dyeing water(pH3, pH5, pH7). Dry cleaning fastness showed over 3 degree in all dyeing methods. Washing fastness is showed in 2-3 degree; Al in nonmordant, premordant, simmordant and Cu in simmordant are 2-3 degree. Perspiration fastness is nearly 3-4 degree in premordant and simmordant. Perspiration fastness shows high in premordant, simmordant than postmordant. The fastness of light, water, dry cleaning, washing, perspiration shows better nonmordant, premordant, simmordant than postmordant method.
