Abstract:

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 extraction-time were optimized for dye-extraction. The pre-treated silk mordanted with different metallic-mordants viz., alum (5, 10, 15%), stannous (0.5, 1.0, 1.5%), copper and ferrous (1, 2, 3%) in pre, simultaneous and post mordanting methods and dyed in optimized dye-concentration in 1:40 M.L.R for 30 min. The dyed silk was assessed for yarn strength, elongation and colour-fastness properties. Irrespective of mordants pre-mordanted dyed silk yarn with alum (15%), stannous (0.5%), copper and ferrous (3%) showed increased colour-strength and colour co-ordinates and these mordants were used for mordant-combinations. The silk pre-mordanted with (15%) alum showed greater strength and elongation than the other samples. All mordanted samples exhibited good-excellent fastness properties compared to control.
