본 연구에서는 한국 특산종으로 남해안 섬에서만 자라는 황칠나무(Dendropanax morbifera Lev., 황칠이라고 함)를 사용하여 염색하였다. 황칠나무는 면역력 증진, 신경 안정, 항균, 항산화에 효능이 있는 것으로 알려져 있다. 황칠염색은 $60^{\circ}C$에서 이루어졌으며, 발효한 액체 황칠을 염료로 사용하였다. 매염제에 따른 염색을 실시하고 CCM을 사용하여 색발현 특성을 알아보았다. 면직물의 경우 대조직물의 K/S값이 0.13에 비해 식소다 동시매염, 고백반 식소다 동시매염, 고백반 동시매염, 고백반 선매염, 황수(영천지역의 약수) 후매염은 각각 1.53, 0.99, 1.62, 1.65, 2.21로 차이가 있었다. 울직물의 경우 대조직물의 K/S값이 0.48에 비해 식소다 동시매염, 고백반 동시매염, 고백반 식소다 동시매염, 고백반 선매염, 황수 후매염은 각각 2.61, 1.97, 3.20, 3.07, 4,59로 차이가 있었다. 견직물의 경우 대조직물의 K/S값이 0.30에 비해 식소다 동시매염, 고백반 동시매염, 고백반 식소다 동시매염, 고백반 선매염, 황수 후매염은 각각 2.06, 1.21, 1,77, 1.80, 3.23로 차이가 있었다. 황수 매염이 식소다나 백반 매염보다 효과가 있는 것을 알 수 있었으며, 매염의 순서에 따라서도 차이가 나는 것을 알 수 있었다.

This study was conducted to clarify the effects of different natural mordants and mordanting methods on the dyeing degree of silk using extracts from Coreopsis drummondii. Surface colors were shown as an order of descent Y in control, and an order of descent Y and YR treated by mordants. Extracts from Coreopsis drummondii was sufficient for the natural dyestuffs. $10\%,\;20\%\;and\;30\%$ mordants made from lime-juice of Camellia japonica, oyster shells. and Symplocos chinensis (Lour) Druce for. pilosa (Nakai) Ohwi were used for the dyeing of silk. Surface color of silk was not affected by the concentration of mordants and mordanting methods, however, $20\%$ mordant was suitable for the dye coloring. It was shown that dye coloring concentrations were highly in the order of mordanting later > mordanting ahead > co-mordanting, and so on. Silks were naturally dyed by the extracts from Coreopsis drummondii, and twenty-nine kinds of natural mordants were treated and screened. Surface color of silk was shown as an order of descent YR treated by the mordants made from the lime-juice of Camellia japonica and Eurya japonica, and as an order of descent Y by the other mordants. By the treatment of natural mordants, concentrations of dye coloring were significantly increased compared with control (none-mordanting), and the potentials as a natural mordant for the effective dye coloring was sufficiently ascertained.

The purpose of this study was to investigate dyeing properties of cotton fabrics by American fleabane extract. Effect of dyeing condition on dye uptake and effect of mordanting on dye uptake, color change and colorfastness were explored. Its affinity to cotton fiber was considerably lower than wool, and its hydrogen bonding was involved in the absorption of American fleabane colorants to cotton fiber. K/S value of pre­mordanting was higher than sim-mordanting or post-mordanting. Except that Sn mordanted showed high K/S value, it did not significantly increase. American fleabane produced mainly yellowish color on mordants and mordanting method. Cotton fabrics showed generally high colorfastness except colorfastness to washing.

안개나무 목질부의 열수추출물을 사용하여 한지를 염색하였다. 안개나무 목질부의 추출물을 동결건조하여 만든 염료 분말을 사용하여 제조한 0.0002%(wt) 농도의 염액은 198 nm에서 0.39의 흡광도를 278 nm 에서 0.10의 흡광도를 가지는 자외가시광선 흡수 피크를 나타내었으며 무매염으로도 한지에 염색이 잘 되었다. 염색된 한지는 황색 계열의 색을 나타내었으며, 명반 매염을 하면 $a^*$ 값과 $b^*$ 값이 동시에 증가하여 주황색을 띠는 것을 알 수 있고, 초산동 매염을 하면 $a^*$ 값이 증가하지만 $b^*$ 값이 감소하여 적색을 좀 더 많이 띠게 되었다. 염화철 매염을 하면 $b^*$ 값만 크게 감소하여 녹색계열의 색을 나타내었다. 닥섬유에 염색시 온도가 증가함에 따라서 염착량은 감소하는 경향을 보였고, 양이온화 섬유를 사용하면 염착량이 크게 향상되나, $a^*$값이 더 크게 증가하여 색상이 적황색으로 변하였다. 표면 전하밀도와 염착량은 정비례의 관계를 나타내었으며, 양이온화 정도가 높아질수록 제조한 색한지의 광견뢰도는 악화되었다.

In this study, simultaneous mordanting method of dyeing in the Caesalpinia sappan dye liquor mixed with the rice straw ash solution was employed. The dyeing effects were compared and reviewed according to the changes of dyeing mechanisms of pre-mordanting and simultaneous mordanting using ash solutions. By the direct addition of the ash solution, the pH of the liquor was abruptly changed. In the case of maintaining the pH value of the ash solution at about 7 or 8, compared to the pre-mordanting, $a^{*}$ values increased and $b^{*}$ values decreased. As a result, it is highly desirable in terms of selective emphasis on the reddish hue. The color development, differentiated from that obtainable by the dyeing of chitosan pre-treated fabric, was obtained due to the effect of the water soluble chitosan component on the dyeing mechanism.

This study was carried out to investigate the chemical and dyeing properties of Petasites japonicus leaf extract under the various extracting and dyeing conditions such as temperature, time, the ratio of water and pH, repetition of dyeing in silk and cotton fabrics with Petasites japonicus leaf. The results were as follows: 1. It was found that λ$_{\max}$ of color solution extracted by Petasites japonicus leaf has two peaks at 290nm and 323nm. 2. The optimum extracting conditions were studied at 10$0^{\circ}C$, 40min., pH 7 and 1 : 20(the ratio of water and Petasites japonicus leaf), the optimum dyeing temperature, dyeing time, dyeing pH and repetition of dyeing were 10$0^{\circ}C$, 60min., pH 7, repetitions of three times, respectively. 3. Silk and cotton fabrics dyed with Petasites japonicus leaf extract were colored yellowish orange. The colory Petasites japonicus leaf extract in silk and cotton fabrics were deeped by same-mordanting with aluminum potassium sufate and cupric sulfate. 4. Washing fastness of silk fabrics was 4∼5 grade, but cotton fabrics was 3∼4 grade, so washing fastness of silk fabrics washed with neutral detergent was excellent.

The purpose of this study is to investigate the efficacy of juglone, which shows hish affinity to wool, for hair dyeing as a natural dye. Before dyeing hair with juglone, virgin hair was bleached by a conventional method using hair shops in the city. In order to study the dyeing properties of juglone on hair, the effects of dyeing conditions on dye uptake, color, tensile strength, and morphology were investigated. And the effect of Fe-mordanting on color change was also investigated. Dye uptake changed marginally as dye concentration increased in the range of 0.02-0.04g. Dye uptake increased progressively is dyeing time increased in the range of 10-20 min. Juglone produced YR colors on hair and the color of dyed hair got duller as juglone concentration increased. The hair was little damaged by bleaching, but cuticles were melted and stripped away by dyeing for longer time. Tensile strength retention decreased up to 65% at 20 min dyeing. Simultaneous mordanting with Fe did not improved dye uptake, but led to darker brown color compared with unmordanted hair.
