Morinda citrifolia extract uses

In our search for a good natural yellow dye, Reseda luteola L fresh extract of the flower, stem and leaves was found to have good colorant quality.As the dyed cotton, silk and wool fabrics as well as yarn showed very good wash and light fastness properties, exploration of dyeing potential of this wonderful dye extract under different pretreatment conditions, mordanting-pre and post with metal mordants, biomordant, enzymes and surfactants were carried out.Our study with Reseda extract showed the following results-bright yellow color with alum, olive green with copper sulphate and dark brown with ferrous sulphate.Sodium salt of Dodecyl benzene-sulphonic acid (SDBS) and Cetyl trimethyl ammonium bromide (CTAB) as pretreatment have also been used.Combination of other natural dye extracts with Reseda extract has been attempted.A wide spectrum of colors has been obtained ranging from canary yellow to olive green to orange.
