복분자 추출물에 의한 면직물의 염색성

Abstract

For the purpose of application to natural fruit as a dyestuff , the dyeability of Rubus coreanus Miquel fruit extract was analyzed. Cotton fabrics were dyed with this extract according to various dyeing conditions. And the effects of mordanting conditions were examined color changes as color differences and color fastnesses. The dyeaffinities were increased gradually as were increased dye concentration. The dyeing temperature was effective in the lower temperatures than higher's. The proper dyeing time and dyeing repetition were 30 minutes and 3 times. The dyeaffinity was decreased at mordanted conditions except post mordanted-Fe, and color difference was increased distinctly at post mordanted condition, especially at post mordanted-Cu. The colors of dyed cotton fabrics were RP, BG, GY, and PB. Light, Washing and perspiration fastnesses were not improved on pre and post mordanted cotton fabrics.
