메리골드 추출염액을 이용한 견직물의 염색특성에 관한 연구

Abstract

In this paper, Tagetes extracts were extracted from leave, root, stem and flower at 100℃ for 20 minutes. Silk fabrics were dyed with Tatetes Patula L. to investigate the dyeing properties in accordance with dye concentration, pH, temperature, time of pre-, simul- and post-treatment of mordants using the three types of mordants. As a result, the surface color of the silk fabrics was yellowish regardless of the types of mordants. However, the a values were decreased and b values were increased in the order of the dyeing using Al〉Cu〉Fe: Al mordanted silk fabrics were appeared in greenish yellow and Fe mordanted silk fabrics were done in redish yellow. K/S values of the silk fabrics treated with Fe mordant were 3 times higher than those of Al and Cu mordants according to the increase in dye concentration. This behaviour was shown even in the increase of mordant concentration due to the interaction of mordant and pigments of Tatetes Patula L. But, the types of mordants did not affect because the equilibrium was obtained in 20 minutes in a similar way. And it showed that the highest K/S value of the silk fabrics studied was pH 4 and 80℃ regardless of the types of mordants.
