"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 from
the black carrot were performed directly in the dyebath. An ultrasonic bath at 80 °C for 60 minutes was used to increase
extraction efficiency. All the dyeing processes were carried out at 100 °C for 60 minutes, both with and without some
metal salts, using two different dye concentrations in 1:1 and 1:10 ratios (material weight:dye extraction volume). Six
different metal salts, i.e. K2Cr2O7, CuSO45H2O, FeSO47H2O, SnCl22H2O, ZnSO47H2O, KAl(SO4)2.12H2O, were used
in the dyeing processes, according to pre- and simultaneous mordanting methods. After the dyeing processes, the dyed
samples’ CIE L*a*b* and color efficiency K/S values were determined by spectrophotometry. The SEM and FTIR data
of 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 were
obtained for the dyed samples. The findings of the study indicated that the dyeability performance of wool and cotton
fabrics with black carrot (Daucus carota L.) extract could be greatly influenced by the mordant used and its application
method."
