Color Characteristics of Silk Fabrics according to Dyeing Sequence and Mordant Type in Combination Dyeing using Yellowish Natural Dyestuffs and Indigo

This study was conducted to find green color diversity through combination dyeing of natural dyestuffs. Silk fabrics were dyed in combination with good fastness of natural indigo and yellowish natural dyes. Following combination dyeing, three kinds of mordants were treated. The color characteristics of silk fabrics with combination dyeing were measured. The greens of silk fabrics displayed slight differences according to the combination dyeing sequence. It was found that dyeing with indigo followed by yellow resulted in good green color ( GY, G, BG ). The green represented by the concentration of indigo (niram) showed a slight difference. Green colors ( GY, G, BG ) were more strongly expressed when the concentration of indigo was 5-10 g/l. The green color of combination dyed fabrics showed a slight difference according to the kind of yellowish natural dyestuffs used. The use of turmeric and Amur cork tree was more effective than the Japanese pagoda tree after dyeing with indigo first. When dyeing with indigo followed by a yellowish dye, color characteristics were different according to the type of mordant. Additionally, the color characteristics of silk fabrics treated with mordants were not significantly changed compared to fabrics not treated with mordant for dyeing with Japanese pagoda tree and turmeric. However, the color characteristics of silk fabrics dyed with Amur cork tree were slightly changed.
