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.

거북꼬리의 적정염색 조건을 구명하기 위하여 열수 및 알칼리추출물을 사용하여 염색조건에 따른 염착량(K/S) 및 Munsell의 색상(Hue), 명도(Value), 채도(Chroma)의 변화에 대하여 조사하였다. 면, 한지, 실크에 대한 열수 및 알칼리추출물 처리 염색물의 최대흡수파장(${\lambda}max$)은 400 mm였다. 염색조건에 따른 염착량은 온도와 시간 조건에서 실크 염색물이 높은 수치를 나타내었고, $80\;^{\circ}C$와 40분을 전후로 큰 변화를 보이지 않았다. 농도조건에서는 농도가 높을수록 급격히 증가하는 경향을 나타내었다. Munsell의 색상은 온도와 시간조건에서 알칼리추출물 처리 염색물은 YR (Yellow Red) 계열의 색상을, 열수추출물 처리 염색물은 R (Red) 계열의 색상을 나타내었으며 온도는 $80\;^{\circ}C$, 시간은 40분을 전후로 큰 변화가 없었다. 명도 및 채도는 뚜렷한 변화를 보이지 않았고 염색조건에는 큰 영향을 미치지 않는 것으로 사료된다. 따라서 거북꼬리추출물로 염색할 경우 최적 염색조건은 온도 $80\;^{\circ}C$, 시간 40분, 농도 100% (추출원액)로 조절하는 것이 바람직할 것으로 생각된다.
