Acacia Nilotica pods: A natural dye source for textile colouration

The ban imposed on the usage of synthetic-dyes has led to the reinvention of natural-dyes throughout the world. Today, the faded antiquity is unveiling due to the concern manifested globally for saving the environment from pollution. In this experiment the dried Acacia nilotica pods and degummed mulberry-silk yarn were used. The powdered Acacia nilotica (5, 10, 15, 20g) was soaked overnight in different M.L.R (1:20, 1:30, 1:40) to optimize the dye-concentration and it was extracted by aqueous-method. Based on the reflectance and colour-strength, 10g dye-concentration, 1:30 M.L.R, 30 min extractiontime were optimized for dye-extraction.
