Natural dyeing is become an essential interest, while ordinary dyeing consumes more water
and leaves toxic effluents. Since the plant is one of the most abundant sources of natural dye and much
literature is available in this regard, it was attempted to investigate the potency of Melia azedarach
leaf as a source of natural dye to achieve some shades on wool fabric using alum, ferrous and copper
salts as mordant. Natural dye material from dried leaf powder was extracted through Soxhlet apparatus
using ethanol solvent. Wool fabric was dyed by exhaust dyeing method following pre and meta-mordanting techniques with 20% extract and effluent solution (re-use). The color properties and rubbing
fastness have initially been investigated in this work. Results showed that color properties do not vary
with mordanting methods rather change with mordant and solution history (first use/re-used). It was
determined that rubbing fastness is strongly related to color properties like color strength and color
depth, and the fastness values for the dry and wet samples was nearly same. The best rubbing fastness
has been achieved only when color depth is minimum. The color difference value was exposed higher
for meta mordanting except copper mordanted sample. A variety of colors were produced for mordanted samples, and the used solution offered satisfactory rubbing fastness property.
