Abstract:

Natural dyes produce special aesthetic qualities which are environmentally friendly, add value to textile production as craftwork and as an industry. Today, many are rediscovering the joy of achieving colour through the use of renewable, non-toxic, natural sources. The dried Acacia nilotica pods were powdered by using traditional pounding technique and was soaked overnight in plain water with varied concentrations (5, 10, 15, 20) and M.L.R (1:20, 1:30, 1:40). The soaked solution was subjected to aqueous extraction method to optimise the dye concentration by using colour strength and reflectance value. The optimised dye extract (10g, 1:30, and 30min) was further used for dyeing silk yarn. The results showed that, irrespective of mordants and mordanting methods myrobolan treated silk yarn dyed with alum(15%), stannous chloride (0.5%), copper and ferrous sulphate (3.00 %) in pre mordanting method showed significantly increased colour strength with decreased reflectance value resulting into darker shades i.e., olive green to brown colour. Acacia nilotica pods can effectively be used as natural dye source on silk for producing varied eye cooling, soothing colour and colour combinations with better colour fastness.
