The Dyeability of Silk Fabrics with Annatto Extract

안나토 추출액을 이용한 견직물의 염색성

This study was investigated for the dyeing properties of silk fabrics with Annatto Extract. The dye stuff was extracted by distilled water at 60$^{\circ}C$, 10minutes, 100:1 of bath ratio. The highest K/S value was showed at 25% dye concentration, 60minutes of dyed time at 50$^{\circ}C$ in the temperature. The post mordant conditions were better than that of pre mordant, especially post-Fe mordant showed highest K/S value. The laundering fastness was relatively good by Cu-mordant. Drying cleaning fastness appeared 4-5 grades.
