감지의 재현을 위한 한지의 전통 쪽염색 특성

Abstract

The study investigated the dyeing properties of Hanji dyed with Indian indigo powder and Niram, a traditional mud-like indigo precipitate with shell-lime, to reproduce Achoengji (or Gamji), the Korean traditional indigo-dyed paper. The dyeing yield and color difference increased with increasing of the dyeing time in the first dyeing process, which was performed by a stepwise manner of increasing dyeing time of yellow Hanji by 5 minutes from 5 to 85 minutes using Indian indigo powder. They increased rapidly up to 15 minutes, and then steadily increased until 85 minutes. The second dyeing process was repeated with the dried indigo-dyed Hanji as the same dyeing manner in the first dyeing process. The dyeing yield and color difference were similar or a bit higher to those of the first process from five to forty minutes of dyeing time. After 40 minutes of the dyeing, those even were decreased unexpectedly. From these results, it was believed that the appropriate dyeing time was between 15 and 30 minutes. A dyeing solution produced by the fermentation of Niram in a traditional method was also used to compare the color changes by the repetition number of dyeing (15 minutes dyeing – 15 minutes development). The dyeing yield and color difference increased with an increase in the dyeing number, and the hue was also changed G→BG→B→PB, respectively. The hue was 1.9G dyed indigo paper in the single time, and the PB color of dyed indigo paper was started to appear after the 8-times dyeing. The color factor similar to those of the antique indigo paper used in this study was appeared in 30-times dyed indigo paper, showing a color difference of 9.82, color yield of 8.56, and hue of 6.0PB. Nevertheless, the dyeing number could be reduced by the fact that the color factor of indigo-dyed paper depended on the indigo contents in the fermented indigo solution.
