In this study, two hats and a laptop bag were developed and produced as cultural products by using Hanji-fabrics dyed with various natural dyeing materials. First of all, for the cultural product development, I selected Hanji-fabric which made with traditional Korean paper with excellent durability and functionality. Secondly, it was dyed blue with indigo, brown with green persimmon juice, red by safflower, yellow by amur cork and purple by gromwell root. Third, two hats and a laptop bag were designed. Fourth, according to the designs, patterns of two hats and a laptop bag were made. And then two hats and a laptop bag were finished by cutting and sewing Hanji-fabrics dyed in various colors.

천연염색은 자연의 식물, 광물, 동물 등에서 염료를 추출하여 직물에 착색하는 것을 의미한다. 합성염료가 발명되기 이전까지 천연염료를 이용하여 의류 및 생활용품 등의 직물에 염색을 하고 인체에 장식을 하였다. 천연염색 중 대부분은 식물성 염료로서 식물의 껍질, 줄기, 열매, 뿌리 등으로부터 색소를 얻을 수 있다. 이러한 천연염색은 그 색상이 차분하고 은은하며, 생리적 측면에서 항균성, 소취성이 있으며, 염색공정이 환경친화적인 저공해 염색으로 알려져 있다. (중략)

천연염색의 색상다양화를 위하여 단백질 섬유인 양모직물에 쪽과 괴화를 이용하여 복합염색을 실시하였다. 복합염색시 쪽염액으로 먼저 염색한 후 괴화염액으로 복합염색한 경우가 괴화염액으로 염색한 후 쪽염액으로 복합염색한 경우에 비해 염착량이 크게 상승한 것으로 나타났다. 복합염색시, 양모직물의 경우 색상의 다양한 효과는 괴화로 먼저 염색하는 것이, 중간색상 발현의 경우에는 쪽으로 먼저 염색하는 것이 효과적이었다.

폐기되고 있는 땅콩껍질로부터 재활용이라는 로하스 개념을 적용한 천연염색 자원개발 측면에서 땅콩껍질의 색소 추출을이용하여 나일론직물의 염색성, 염색 견뢰도와 더불어 기능성을 토하고자 하였다. 볶은 땅콩(학명 Arachis hypogaea)의 외피를 분리하여 땅콩껍질 5kg에 증류수 10L을 가하여 $100^{\circ}C$에서 120분간 환류시켜 색소를 추출 여과하였다. 매염제는 시약은 1급을 그대로 사용하였다. 시료는 KS K 0905에 규정된 염색 견뢰도 시험용 정련된 표준 나일론직물 사용 하였으며 염액의 욕비 1:50, 시간에 따른 염색조건, 염색온도, pH, 반복 염색성은 $100^{\circ}C$에서 90분씩 염색하여 건조하는 순서로 6회 반복 염색하였다. 염색온도가 높아질수록 시간이 길어질 수록황색이 점차 진해지며 온도 증가함에 따라 K/S값과 ${\Delta}E$값이 점차 증가함을 보여주고 있다.

Korea boasts outstanding cultural heritage accumulated over the 5 thousand-year-long history, but has neglected developing marketable commercial products out of its culture. As a result, despite the fact that Korea had successfully developed internationally well-acknowledged technologies, there isn't any exceptional cultural product that can be marketed globally. Therefore, it is necessary to re-design and commercialize a modern sense using unique materials in traditional culture. Fabrics made by natural dyeing have a low saturation, so they do not need special color harmony, they are natural and comfortable. Therefore, fabrics obtained by natural dyeing are considered to be a very suitable material for cultural product development. In addition, Hanji is a good material that can build a field of art by itself because it has a quality, a profound and elegant feeling. In this study, Hanji-fabric, which is made of excellent Hanji, is used for natural dyeing with. Using the dyed fabrics, the cultural products such as two parasols and a card holder was made and presented.

This study was carried out in order to investigate color sensation and sensibility for yellowish natural dye fabrics and reddish ones and to establish prediction models for color sensibility factors of them by color sensation and the related physical measurements focusing on 40s middle-aged people. Eight fabric stimuli which were dyed with a variety of yellowish or reddish natural dyes was subjectively evaluated in terms of color sensation and sensibility by 40s aged participants. As results, three color sensibility factors including 'Active', 'Characteristic', and 'Relax' were extracted and they were examined in respect of their relationships with color sensation and physical color properties. Color sensibility factor 'Active', the dominant factor for the naturally dyed fabrics was explained by $L^*$ and sensation 'Deep' in its predictive model and a yellowish fabric dyed with 300% solution of armur cork unmordanted was perceived the strongest in the factor. Factor 'Characteristic' was predicted by both $a^*$ and sensation 'Light' and reddish natural dye fabrics tended to be felt more strongly for it. Color sensation 'Strong' was the only predictor for factor 'Relax' in that naturally dyed fabrics with lower values for the sensation seemed to show higher 'Relax' factor and a reddish fabric dyed with safflower 125% was the highest for the color sensibility factor. These results could be utilized to design color-sensible natural dye fabrics for middle-aged people.

This study dyed rayon fabric using loess as a natural colorant. To obtain the optimal dyeing conditions, various dyeing conditions were examined (temperature, pH, time, and concentration). The color fastness was evaluated using standard washing and rubbing fastness tests. The results were as follows: The loess powder particle size ranged from 0.4 to $1.7{\mu}m$ with a distribution range of 1.1 to $1.4{\mu}m$, representing a fine and uniform manufactured loess powder. The loess component analysis showed a large amount of silicon dioxide and aluminum oxide. TheFT-IR spectra showed that the ammonium group in the rayon fabric produced N-H banding at $1,540cm^{-1}$. The highest K/S value for the rayon fabric was obtained when the pH was 8.0, and this value increased rapidly with a longer dyeing time and when increasing the loess concentration to 30% (w/v). Pre-treatment with a soybean solution produced the highest K/S value for the rayon fabric with a loess concentration of 30% (w/v). The SEM analysis showed a higher amount of loess adhered to the rayon fabric surface when increasing the loess concentration. However, pre-treatment with a cationic agent and soybean solution resulted in a much higher attachment of loess to the fabric surface. Thus, the experimental results showed that using a cationized fabric and pre-treatment with a soybean solution are more effective when dyeing rayon fabric with loess than when using only loess.

This study was carried out in order to investigate the colorimetric values, the color sensation and sensibility for naturally dyed fabrics with microbial prodiginine colorant and to find out the relationship among color sensation, color sensibility factors and colorimetric properties of them. Color sensation and sensibility of four different fabric stimuli coloring red purple by a microbial prodiginine colorant produced from Zooshikella sp. were subjectively evaluated by university students. The color sensibility for the naturally dyed fabrics was classified into four factors: 'pleasantness', 'gracefulness', 'characteristic' and 'relax'. Color sensibility factor 'pleasantness' was the dominant factor for the naturally dyed fabrics with microbial prodiginine colorant. All color sensibility factors showed a significant correlations with the color sensation and colorimetric properties of the dyed fabrics with prodiginine. There were showed significant relationships between the color sensibility factors and lightness $L^{\ast}$, color saturation $C^{\ast}$, $a^{\ast}$ and $b^{\ast}$. Also, color preference of the dyed fabrics with prodiginine was found to be influenced mainly by color sensibility factors.
