Abstract

K/S values, Hue, Value, and Chroma changes of the hot-water and alkali extract of Boehmeria tricuspis have investigated to obtain an optimum dyeing conditions. Maximum optical absorption of the cotton, Hanji, and silk dyed with the extract were observed at 400 nm. The K/S value of the dyed silk was higher than those of other materials in the treatments with the temperature and time condition and there was not much changes in the treatments near $80\;^{\circ}C$ and 40 minutes. Also, the K/S value of the dyed silk was drastically increased as the concentration of the dye was increased. In the treatments with temperature and time condition, Hue of the materials dyed with alkali extracts resulted in YR color, whereas materials dyed with hot-water extracts provided R color. In the time and temperature condition of treatment, there were no significant changes in the samples treated near $80\;^{\circ}C$ and 40 minutes. The Value and Chroma of the dyed materials were not significantly changed. As a result, it is suggested that the optimum temperature, time, and concentration of dye would be $80\;^{\circ}C$, 40 minutes, and 100%, respectively, when cotton, Hanji, and silk are dyed with Boehmeria tricuspis extract.
