This study was conducted to clarify the effects of mordanting conditions on the dyeability of silk fabrics by natural dyes extracting from african marigold plants. Five minute coloring process seemed to be enough because the surface color of the silk fabrics showed negligible difference between coloring time spans. In the case of coloring copper sulfate, alum and calcium hydroxide, L-value marked low at the 70-80℃ and △E-value did relatively high. But the coloring with sulfate of iron and cider vinegar was not affected by the temperature. The result of treatment with 1%, 3% and 5% of mordant indicated that L- and △E-value of the surface color of the silk made no meaningful difference by the mordant concentration. When alum and calcium hydroxide are treated with a post-coloring method, L-value marked low and △Evalue did relatively high. Others made no significant difference according to coloring methods. Observing the surface form of the colored silk through SEM revealed that textiles got damaged with a caustic soda treatment.
