In this present work, the flowers of the centaury (Hypericum scabrum L.) were extracted with distilled water. Different transition element salts were used to obtain stable and different colours with high fastness. AlK(SO4)(2)center dot 12H(2)O, Bi(NO3)(3)center dot 5H(2)O, CoCl2 center dot 6H(2)O, CuSO4 center dot 5H(2)O, FeSO4 center dot 7H(2)O, K2Cr2O7, MnSO4 center dot 7H(2)O, SnCl2 center dot H2O, ZnCl2 were used as mordant substances. According to preliminary, together and last mordanting methods, wool, silk and cotton fibres were. dyed at pH 4, pH 8 and at 90 degrees C, seperately. In addition, the effect of the artificial animal urine system (NH2CONH2 (3 %, m/v), NH3 (3 %, v/v), CaC2O4 (3 %, m/v)) as a mordant substance on dyeing of woollen materials was studied using together-mordanting method. The optimum dyeing conditions were determined and the results were evaluated in terms of fastness of dyed samples.
