초록

The purpose of this study is to examine the influence of the pigment characteristic and changes in dying conditions on the dying properties by extracting Chelidonium majus var. asiaticum using distilled water and ethanol as solvents.
Changes in dying conditions include variations in dye concentrations, dyeing temperatures and time on dye uptake, and K/S Value was compared according to these changes. Additionally, color changes were observed through mordant.
Ultraviolet-visible spectrum was used to investigate the pigment characteristic, and as a result, tannin was identified in distilled-water-extract, whereas berberine and chlorophyll were identified in ethanol-extract. In FT-IR analysis, tannin in distilled-water-extract was verified as hydrolyzable tannin. For ethanol extract, chlorophyll was verified through absorption band of C-H, which is aliphatic spectrum around 2920 cm -1 and 2850 cm -1 . From GC/MS analysis, oil components as well as terpine compounds were detected in ethanol-extract, and this, in turn, brings expectation regarding functionality. When dying in silk, dye uptake increased as concentration of the extract increased, and the optimum dyeing temperature and time were 40 ℃ and 60 minutes respectively. Dyed fabrics’ colors were all basically Y-series colors, and adjustment in brightness and revelation of khaki color were also available depending on the type of the mordant. Color fastness, except for washing fastness, was good in silk dyed with distilled-water-extract. Thus, it can be concluded that by selecting the right extracting method and by doing proper dyeing and mordant according to the needs, these dyed fabrics can be used as eco-friendly, functional clothing material.
