The purpose of this study is to investigate the effect of mordanting condition in the Gardenic Jasminoides Ellis Dyeing. The results were as follows; 1. The color fastness was compared and analysed that colored sample as $AIK(SO_4)_2,;CuSO_4{cdot}5H_2O,;Ca(OH)_2,;NaOH,;HOOC(CHOH)_2COOH,;K_2;Cr_2O_7$ group was better than non-colored sample and also a silk was better than a cotton in fastness. Mordant as NaOH, HOOC$(CHOH)_2COOH,;K_2Cr_2O_2,;AIK(SO_4)_2$ were better than anything else in fastness and the effective method of the mordant to a silk was pre & aft mordant(4) and to a cotton was aft-mordant(3). 2. The comparison between methanol and distilled water, which used in extracted dyenig solution, the latter was more than one grade in fastness. 3. The color-difference value-test indicated that colored sample groups more redish and bluish color than non-colored sample. 4. The comparison between methanol and distilled water, which used to extract dyeing solutions, the latter were more light, greenish and yellowish colors. 5. When compared with the methanol and distilled water, as used to extract dyeing solutions, showed that the methanol was more clear and light yellow and the distilled water was more orange color and more effective in color fastness.
