Abstract
This study shows the dyeability and antibacterial activity about cotton and silk fabrics dyed with Chrysanthem indicum L. In the case of dyeability, in the first, K/S value was shown comparatively high numerical value. The value of all test sample was over 20. In the next, in the case of colorfastness, the light colorfastness showed the lowest grade, the other colorfastness was relatively good. However there are some differences according to fabrics and mordants. In the case of antibacterial activity to Klebsielia pneumoniae, the cotton fabrics had the most antibacterial effect at the dyed fabrics that had been mordanted $CuSO_4$.$5H_2O$, and the silk fabrics had the most antibacterial effect at the dyed fabrics that had been mordanted $CuSO_4$.$5H_2O$.$Al_2$ and $(SO_4)_3$.
