TLDR
In this article, the influence of dyeing process conditions such as pH, concentration of dyestuff, and the addition of electrolyte has been studied to obtain a specific purple hue.Abstract:
The objective of this research is to optimize the dyeing parameters for cotton fabric with natural dyestuff extracted from Dactylopius coccus. In order to obtain purple hue, the influence of dyeing process conditions i.e. dye bath pH, concentration of dyestuff, and the addition of electrolyte has been studied. Additionally, potassium aluminium sulfate dodecahydrate and iron (II) sulfate heptahydrate were used as mordants on cotton fabrics in order to obtain coloration of specific purple hue. Colorimetric data and fastness properties of the dyed samples have been analyzed. Results indicate that the dyeing parameters as well as pre-treatment has a significant influence on the obtained purple shades and fastness properties.read more
