This study was carried out the effect of stability and color extract for it`s condition in the curcuma L.. dyeing. The stability is to investigate the absorbance of the curcumin, one of the major yellow pigments and the stability regarding the effect of light, oxygen temperature and pH. The dyeing condition is compared the effect of mordanting condition and the best way to extract pigment and analysed through the color-fastness rating, color-difference value test. The main results obtained are summarized as follows; 1. The best and proper solvent to extrect curcumin pigment was a ethanol and a distilled water. 2. The light effect indicated that the absorbances of solution in absence of ligh was more stable. 3. The oxygen(O_2) effect to curcumin showed that the condition in the absence of O_2 was more stable than that in presence of O_2 4. The temperature showed that the absorbance was best stable in 4℃ and less changed at 25℃. 5. The curcumin-etanol solution was stable in pH 2∼4. 6. Generally color-fastness rating to silk, wool and cotton indicated that crocking C.F. and perspiration C.F. were more than 3rd grade and dry cleaning C.F. was more than 4th grade. But light color-fastness and washing color-fastness were very poor. 7. To make good color fastness, the mordanting treated group and the pre-mordant conditions were more effective than others 8. When compared with color-difference value test indicated that the silk was looks like more reddish and bluish color and than the wool and cotton were greenish and bluish. As a mordant, A(C_2H_4OH(COOH_3) and D(K_2Cr_2O_7) were more effective to make greenish color in the silk and the reddish color was abtained by B(Al.K(SO_4)_2.12H_2O) and C(FeSO_4.7H_2O).
