Abstract/Description: | Dyes obtained from plants, invertebrates, minerals etc. are known as natural dyes. In the recent past, synthetic dyes had gained popularity due to ease in processing. But in recent times, rebirth of natural dyes as an alternative to the hazardous synthetic dyes has received a worldwide attention. This is virtually a global hunt for eco-friendly dyes as they are non-toxic, biodegradable and safe. Eri silk (Samia ricini), is known as ahimsa silk, as it is much more humane to the creatures creating the silk and North- east India is known as the homeland of Eri silk. Combination of different natural dyes produces different shades. Dyeing eri silk with different natural dye enhances the quality and aesthetic value of the fabric. Moreover, it gives a new look to the fabric so as to help in product diversification. And being eco- friendly it can be effectively used for dyeing. With this consideration, a study was undertaken in College of Community Science, Assam Agricultural University, Jorhat-13 on dyeing of eri silk fabric with combination of two natural dyes i.e. annatto (Bixa orellana) seed and fresh tea (Camellia seninsis) leaves. In this study, the dyeing was carried out in aqueous as well as alkali medium by using different mordant such as Aluminium potassium sulphate [Alk(SO4)2. 16 H2O], Copper sulphate(CuSO4), Stannous chloride(SnCl2) and Ferrous sulphate(FeSO4) and also mordanting methods. Combination of different mordants and mordanting methods resulted in beautiful hues. The colour fastness properties of dyed fabrics were recorded to be very fair to good, as per the rating scale. The colour yield obtained from combination of annatto seed and tea leaves on dyed eri silk fabric were dark goldenrod, old gold, sepia and taupe. |
