초록

This research investigated the effect of pH of dyebath and dyeing temperature on the dyeability of indigotin and indirubin on silk as well as the relationship between the amount of indigotin and indirubin detected from the dyed silk through HPLC-DAD analysis and the color of samples measured using a spectrocolorimeter. Indigo standard dye and indirubin standard dye were deliberately mixed by ratios 100:0, 80:20, 60:40, 40:60, 20:80, and 0:100 to dye silk with a different pH of dyebath (7, 11) and different dyeing temperatures (50°C, 70°C). The amount of indigotin and indirubin pigments in silk was calculated using regression equations obtained from standard calibration curves of indigotin and indirubin. A higher indigotin percent ratio resulted in the higher K/S values and the higher amount of indigotin detected from silk. However, higher indirubin percent ratio in the mixed dye did not relate to the higher indirubin pigment detected in silk. While indirubin showed low or negative contribution to the K/S values, it showed a higher effect on the color of dyed silk. Higher amounts of indirubin in dyed silk resulted in a darker PB color, which led to P color with increases in indirubin content.
