Abstract
The dyeing of woollen yarn with lac as natural dye has been studied using ferrous sulphate, stannous chloride and their combination as mordants. Fifty four shades have been produced by using different mordants and varying the amount of dye. The hue of colour ranges from light orange - red - dark scarlet. The colour strength (K/S) has been found to be very good in dyed woollen yarn samples. Colour fastness values with respect to light exposure, washing, rubbing were obtained following standard methods. FTIR and SEM studies on dyed samples were also performed. From the investigations and study of dyeing a database on the effect of different eco-friendly mordants and their combination on the depth of shades, colour values and fastness properties of woollen yarns dyed with lac dye was devised. Following conclusions can be drawn based on the experiments of dyeing: Application of lac dye on wool substrate produces a range of shades varying from light orange - bright red - dark scarlet depending on the amount of lac dye, eco friendly mordants and their combination used. Stannous chloride mordanted woollen yarn dyed with lac dye produced stronger colour depth in comparison to lac dyed woollen yarn samples mordanted with ferrous sulphate. Lac dye applied on woollen yarn samples in the presence of both the mordants and their combination has very good light fastness, good wash fastness and moderately good to good rubbing fastness properties.
