The purpose of this research is to revive the colors of combination dyeing and mixed dyeing with natural dyestuffs. The fabrics used were cotton and rayon. The natural dyestuffs used in this research were indigo, Phellodendron amurense, and Caesalpinia sappan. The effects of combination dyeing were as follows. First, all samples showed deeper colors. Second, according to the results of the surface K/S measurement, while the surface K/S of cotton was over 15, that of rayon was over 17. Third, the results of the light fastness measurement showed the superiority (by over grade 4) of all the samples, except in the case of rayon fiber sample no. 6 (which had been pre-dyed with indigo five times before being dyed with P. amurense once and then being dyed with C. sappan once). In the color fastness to washing measurement, all fibers showed superiority (by over grade 3~4). In addition, the color fastness to dry cleaning of all fibers was satisfactory or excellent (by over grade 3). Fourth, according to the results of the tensile strength measurement, it tended to decrease in the case of cotton and increase in the case of rayon. Fifth, the results of the density measurement showed that the density of cotton decreased by about 15~20% in the case of warp and 10% in the case of weft for all samples. The density of rayon decreased 20% in the case of warp for all samples and increased 30% in the case of weft for all samples.
