다국어 초록 (Multilingual Abstract)

This study was to examine the effect of color and colorfastness depended on temperature and dyeing time by using hot water extract form Caesalpinia sappan L. The dyeing temperature was 20oC, 30oC, 50oC, and 70oC and dyeing time was respectively 10, 20, 30, and 50 minutes. The colorfastness was measured by the washing with distilled water, plain shampoo, color shampoo and daylight. As the result, dyed hair color was red and dependant of dyeing time and temperature. The effect of dyed hair which appeared at 30oC for 10 minutes was higher than others. The value of lightness(L*), redness(a*), yellowness(b*) and color difference(E) was measured 47.22, 43.53, 43.78 and 48.06 respectively. The rate of washing colorfastness was decreased with repeated washing distilled water, plain and color shampoo. The daylight colorfastness was largely decreasing as washing. From these results, we can confirm that the hot water extracts from Caesalpinia sappan L. may be useful in the materials of hair coloring dye.
