현대 주거 공간의 색채 유형이 다양화 되고 실내 공기질 관리법이 시행되면서 환경친화형 컬러가구재의 개발이 매우 필요한 시점이다. 따라서 치자, 홍화, 오배자, 자초, 소목 및 밤송이 등으로부터 천연염료를 추출하여 적정한 염색조건을 도출하였다. 천연염료 추출시 용매의 pH가 높아지면서 동일계 색상일지라도 더 짙은 염료가 얻어졌다. 염색에 앞서 천연염료와 목재 조직과의 결합을 촉진하기 위하여 알루미늄, 구리, 철 및 크롬 계통의 매염제를 처리하였는데, 매염제의 종류에 따라 황색, 갈색, 녹색 등의 색상이 얻어졌다. 매염 처리된 목재 시험편에 본 천연계 염료로 염색한 경우 염색시의 pH와 온도가 높아질수록 짙은 색상이 얻어졌을 뿐만 아니라 염액이 목재 조직 내부로 더욱 깊이 침투하였다. 컴퓨터 모델링을 통하여 보여진 천연염색된 컬러가구는 다양한 색상이 요구되는 현대 주거 공간과 조화를 꾀할 수 있어 천연염료가 현대 목가구 제작에 적합한 재료로 사용될 것으로 사료되었다.

This study aims at developing of textile design expressed not only Korean natural image but also modern sensibility using fabrics dyed by tie dyeing with various natural dyes. And it attempts to practicality of high value-added goods revived traditional beauty. With the aqueous extract of various natural dyes, i.e., indigo, amur cock tree, onion's peel, citrus peel, mugwort, gromwell, sappan wood silk fabrics dyed by tie dyeing. Also various color changes were examined by mordants, i.e., aluminium sulfate, cupric acetate mono hydrate, ferrous chloride. With these fabrics, I made works using the techniques of applique, mola, fabric's connection and weaving. I think the developed textile design gave expression to natural image of Korean nation.

Until now, in case of natural dyeing, the appearance of medium colors were achieved by repeat dyeing with different colorants after dyeing with one colorant. In this study, however, new dyeing method for appearance of medium colors was developed by use of mixing solution of different colorants prepared with the same ratio using colorant concentrates. In combination dyeing, purple color was difficult to represent because of the Gardenia blue dye among the colorants used in this study was naby blue dye. But the other medium colors such as yellow red, green yellow, green and blue green were easily represented by use of reddish Sappan wood and yellowish Gardenia concentrates. If the natural blue dye is prepared in concentrate condition, the dyeings dyed in various colors may be obtained by combination dyeing.

This study was carried out on the process of natural dye substances which can flock ultraviolet rays without producing harmful substances by pollution, germs, etc. While making human body safe in contact, extracting Gardenia, Sappan wood, Radix scutellariae, Cromwell, Mugwort, Gallnut, Lac. Those are used for curing diseases, dyeing silk cloth with those extracts, and examining the color fastness, Ultraviolet protection. From this study, the following conclusion was produced. Brightness was lower in pre-mordanting than in post. And color difference showed that Radix scutellariae was the highest. Aluminum-mordanting showed a higher color difference than Fe. Colorfastness to washing was high in all samples, and the degree of color-changing by washing was the highest in the sample dyed by gardenia, pre-mordanted gallnut showed the highest degree. Colorfastness to perspiration was the highest in gardenia. UV-A test showed that all samples a high rate of 85% or higher compared with test white cloth. Especially, post-mordanted radix scutellariae, pre-mordanted gallnut and post-mordanted sappanwood showed a superior blocking rate.

본 연구는 치자나무, 홍화, 오배자, 지치(지초), 소목 및 밤송이 등으로부터 추출한 천연염료를 이용하여 밤나무재를 염색할 때 나타나는 목재 표면의 색상 변화를 정량적으로 분석하여 효과적인 천연염색법을 검토하였다. 목재 시편은 염액의 온도, pH, 침지시간, 반복처리 횟수 등과 같은 다양한 처리조건을 적용하여 다채로운 색을 발현시겼고, 천연염색된 시편의 색상을 정량적으로 측정하기 위하여 $L^*$, $a^*$ 및 $b^*$ 값을 측정하여 채도와 염착농도를 산출해 내었다. 도막처리법은 천연염색 시에 많은 시간을 필요로 하는 침지 처리에 비해서 더욱 경제적인 처리법이라는 것을 확인할 수 있었다. 또한 착색력이 낮은 도막처리법은 반복적인 도막 처리를 통하여 원하는 색상을 얻을 수 있었으며 색상의 농담도 쉽게 표현할 수 있었다. 천연염색 처리 결과 염액의 온도가 높으며 약산성 염료(pH4의 수준)를 사용함으로써 우수한 착색효과를 얻을 수 있었다.

본 연구에서는 천연염료와 직물종류, 매염유무의 세 가지 조건에 대한 천연염색직물의 물리적 색채 특성을 측정하고, 심리적 색채감성평가를 실시하였다. 이에 대하여 염료의 종류, 직물의 종류, 매염제의 유무에 따른 물리적 색채 특성 차이를 살펴보기 위하여 분산분석을 실시하였으며, 상관관계분석을 통해 물리적 색채 특성과 심리적 감성간의 관계를 분석하고, 회귀분석을 이용해 천연염색에 대한 예측식을 도출하였다. 최종적으로, 천연염색직물에 대한 감성 이미지 맵을 제안하기 위하여 다차원 척도법(Multidimensional Scaling: MDS)을 이용하였다. 이를 통해, 대표적으로 남성적인(masculine)인 이미지에는 무거운, 딱딱한 색채감성을 갖는 치자염색이, 여성스러운(feminine) 이미지에는 밝고 투명하고 부드러우면서 가벼운 색채감성을 갖는 소목과 락, 치자청을 사용한 염색이 적합하다. 내츄럴(natural)한 이미지를 나타내기 위해서는 은은한 색채감성의 쑥 염색이 적절하고, 화려한 색채감성의 쪽으로 염색을 한다면 액티브(active)한 이미지를 가질 수 있을 것이라 예측 가능하다.

This study aims to compare the properties of natural dye stuffs, such as color, dyeability, fastness, and marketability, to analyze the differences noted by expert groups regarding the properties of the stuffs, and to make a positioning of the stuffs. A survey of experts in academia, business, and the art of natural dyeing was conducted, with an evaluation of 23 types of the stuff's properties. There is a correlation between the properties of the stuffs, and evaluating dye stuffs differs according to the group to which it belongs. X-axis relates to color and Y-axis refers to fastness in the positioning of the stuff. There are different relationships between properties according to their group. Color is significantly associated with marketability in art experts however, fastness is closely connected with marketability in business. The stuffs can be divided into five clusters. Cluster I includes indigo and persimmon, and is marked by excellent color, dyeability, fastness, and marketability, Cluster II contains safflower and sappan wood, which are excellent colors, yet suffer from low marketability on account of their medium to low fastness. Cluster III includes red, purple, and brown dyes, and onion and rhubarb, and has medium properties. Cluster IV is mugwort and yellow dyes, except onion and rhubarb, and features low properties. Cluster V is loess, featuring medium color and low fastness.

As the substitute of synthetic coloring materials for hair dyeing, we selected some natural ones of three primary colors such as sappan wood, logwood(red), gardenia blue(blue) and amur cork tree(yellow). Mixed colorants and metallic mordanting technique were used to widen the color space of dyed samples. In view of similarity in morphological and chemical structure, wool was adopted as the reference material for human hair to evaluate the color properties of hair dyeing. The color properties of the dyed samples were evaluated by using CIE $L^*a^*b^*$ and Munsell color systems. The addition of an alum or ferrous mordants was effective to expand the color space of hair and to increase the colorfastness to washing and light more than the rating of 1. Displaying the dyed samples by using Munsell color system, better linearity of hue values between the dyed samples of wool and human hair was shown when alum mordant was used.

In order to analysis on color difference of natural dyes, I have dyed Hanji, cotton, silk fabric and exposed them to carbon arc light. The results of experiment have been analysed by wavelength of maximum absorption, amounts of dye uptake, color difference, Hunter's value and Munsell's value. Gardenia Jasminoides is monogenetic dye, but it gained darker color by pre-mordanting method used Al mordant agent and greenish yellow color by Fe mordant agent. whereas Curcuma, an Amur cork, and bud of pagoda tree are shown as greenish yellow color, and A barberry root, Betel nut, and Rhubarb are shown as reddish yellow color. these gained khaki colored dyed fabric by Fe mordanting. In addition, Sappan wood showed great result in pre-mordanting. Especially, it gained dark red color by Al pre-mordanting. The pink color was shown by post-mordanting. and Logwood showed great dyeing result in Hanji and cotton better than silk. Specially pre-mordanting was effective. Hanji and cotton showed greenish blue color by Al pre-mordanting, and silk showed brown color.

In order to analysis on color difference of natural dyes, I have dyed Hanji, cotton, silk fabric and exposed them to carbon arc light. The results of experiment have been analysed by Munsell's value, and compared the difference of colors which were recognized visually. Gardenia Jasminoides is monogenetic dye, but it gained darker color by pre-mordanting method used aluminum mordant agent and greenish yellow color by ferric mordant agent. whereas Curcuma, an Amur cork, and bud of pagoda tree are shown as greenish yellow color, and A barberry root, Betel nut, and Rhubarb are shown as reddish yellow color. these gained khaki colored dyed fabric by ferric mordanting. In addition, Sappan wood showed great result in pre-mordanting. Especially, it gained dark red color by aluminum pre-mordanting. The pink color was shown by post-mordanting. and Logwood showed great dyeing result in Hanji and cotton better than silk. Specially pre-mordanting was effective. Hanji and cotton showed greenish blue color by aluminum pre-mordanting, and silk showed brown color. However the color, which was recognized visually, differed from colorimeter sometimes. Therefore, such color table might be necessary for the natural dyeing.
