Extraction and Application of Natural Dye from Nauclea Diderrichii Heartwood

The study extracted dye from Nauclea diderrichii; ascertained which method and
solvent extracts the dye more efficiently. The extracted dye was applied to cotton
fabric treated with the mordant, alum. The experiment was carried out in
chemistry laboratory University of Uyo. Uyo Akwa Ibom State. Cold maceration
and soxhlet extractions were employed using distilled water and acetone as
solvents. The dye was produced in four states, samples in maceration yielded
yellow and slightly deep yellow respectively while in soxhlet extraction,
samples yielded deep yellow and highly deep yellow. The extracted dyes were
applied on cotton fabric treated with alum. It was therefore concluded that the
process involved in the extraction was eco-friendly. The yellow dye obtained has
the dyeing potential which can be used as a source of textile dyeing.
