"This study has been conducted to find out whether black carrot extract can be used as a dyestuff to dye textile materials.For this purpose, the two most widely used textiles (namely, cotton and wool) have been selected. The extractions fromthe black carrot were performed directly in the dyebath. An ultrasonic bath at 80 °C for 60 minutes was used to increaseextraction efficiency. All the dyeing processes were carried out at 100 °C for 60 minutes, both with and without somemetal salts, using two different dye concentrations in 1:1 and 1:10 ratios (material weight:dye extraction volume). Sixdifferent metal salts, i.e. K2Cr2O7, CuSO45H2O, FeSO47H2O, SnCl22H2O, ZnSO47H2O, KAl(SO4)2.12H2O, were usedin the dyeing processes, according to pre- and simultaneous mordanting methods. After the dyeing processes, the dyedsamples’ CIE L*a*b* and color efficiency K/S values were determined by spectrophotometry. The SEM and FTIR dataof the fabrics were collected and evaluated at the end of the trials as well. At the same time, perspiration, rubbing,washing and light fastness values of the dyed materials were also assessed. Acceptable fastness test results wereobtained for the dyed samples. The findings of the study indicated that the dyeability performance of wool and cottonfabrics with black carrot (Daucus carota L.) extract could be greatly influenced by the mordant used and its applicationmethod."
