초록

The purpose of this study was the efficient use of the black rice bran for dyeing textiles. For this purpose, we investigated proper extracting conditions of black rice bran, dyeability and dyeing fastness of dyed silk fabrics. To find proper extracting condition of black rice bran, we extracted black rice bran with water at different temperatures(, , ), different extracting pH(pH3, pH4, pH5, pH6) and extracting time(20, 40, 60, 80, 100, 120, 140, 160, 180min.). Also we investigated the effect of dyeing time(1, 2, 3, 4, 5, 6hr.), dyeing temperature(, , ) and mordanting method(non, pre, sim, post) to examine dyeability and dyeing fastness of dyed silk fabrics. As a result, when the extracting temperature and time were , 3hr., respectively, extracting was best. And the higher the extracting concentration, the more the extracting amount. As the dyeing temperature and time were higher and longer, the dyeability of silk fabrics was better. With mordant, the dyeability was improved and when using premordant method better, the K/S value was maximized. The laundering fastness of the silk fabrics dyed with black rice bran was estimated to have a good grade of 3~4, however, the light fastness was poor to have a grade of 1~2.
