천연염료의 색채에 관한 연구 -치자색소를 중심으로- = A Study on the Color of Natural Dye -Cape Jasmine Dye-

다국어 초록 (Multilingual Abstract)

Fading gives the change of three characteristic value, i.e., hue, chroma, and value. In order to study on the color of natural dye, authors have dyed ramie, silk, and nylon fabric in dye solution extracted from fruits of Cape Jasmine, and exposed them to carbon arc light. The results of experiment have been analysed by the method of C.I.E. chromaticity diagram, H.V/C color solid, and the determination of three characteristic value of color difference etc.. The results from these analyses are as follows; 1. As the dyeing temperature becomes higher, the hue of Cape Jasmine dye on the silk and nylon fabric gets the shift Y to YR, its value increases and its chroma decreases. 2. The light fading of this dye makes the shift of hue YR to Y; on the nylon and silk singlehue, on the ramie multihue. And also the value and chroma of this dye on the silk and nylon decrease with the light fading. 3. The light fading of Cape Jasmine dye is chiefly caused by the shift of chroma.
