초록

In this research, the dyeing properties of Lycopus lucidus Turcz on cotton and silk fabrics were evaluated to establish a scientific database of natural dyes. The optimum dyeing conditions were identified with K/S values depending on the dyeing concentration, temperature, time, and pH. For the optimum conditions, the color changes for different synthetic mordants were observed as L, a*, b* and H, V, C. The color fastness after dyeing and mordanting was also examined. Additionally, the antibiosis of Lycopus lucidus Turcz was examined. The results were as follows: For the cotton, the optimized dyeing conditions were 300% (o.w.f.), 50℃, 40 min., and pH 5. For the silk fabric, the conditions were 450% (o.w.f.), 70℃, 60 min., and pH 4. The K/S value of dyed cotton improved about 1.03-2.78 folds after mordanting. The fabric color was yellow in the absence of mordanting, while it was reddish yellow after post-mordanting with FFC. Although the color changed with the mordanting method and mordant, the overall hue was yellow. Thus, Lycopus lucidus Turcz appears to have the potential for use as a natural dyeing material for a yellow hue. The K/S value of the dyed silk fabric improved about 1.05-1.40 folds after mordanting. The fabric showed a reddish yellow color when pre-mordanted with Al and Cu. The washing and dry-cleaning fastness of the cotton and silk fabrics were at the 4-5 level. The light fastness of the cotton improved after mordanting; however, pre-mordanting was more effective than post-mordanting or the absence of mordanting. The dyed cotton, silk fabrics showed excellent antibiosis.
