TAILIEUCHUNG - Eucalyptus bark as a source of natural dye for cotton fabric

Natural dye extracted from Eucalyptus bark was applied to cotton fabrics by conventional method of dyeing. Alum, Vinegar, Myrobolan, Betel leaves, Copper sulphate (CuSO4), Alum + CuSO4, Vinegar + CuSO4, Myrobalan + CuSO4, and Betel leaves + CuSO4 were the treatments used for mordants. The dyeing was carried out with and without mordants by pre-mordanting method. The colour of each dyed material was investigated in terms of CIELAB (L*, a* and b*) and K/S values by perimer color scan. The colour fastness to washing, rubbing (dry and wet), light and perspiration of aqueous dyed fabrics were tested according to ISO standards. Results showed that cotton dyed fabrics without mordant showed a shade of reddish brown, while other mordants exhibited light to dark brown shades. The colour fastness to washing and perspiration were good except unmordanted fabric which showed moderate to good fastness to washing, whereas colour fastness light and dry rubbing were excellent for all fabrics; wet rubbing was good for all nine fabrics except unmordanted fabric which showed moderate to good fastness. | 2019 8 5 872-882 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 05 2019 Journal homepage http Original Research Article https Eucalyptus Bark as a Source of Natural Dye for Cotton Fabric .

The dyeing was carried out with and without mordants by pre-mordanting method. The colour of each dyed material was investigated in terms of CIELAB L a and b and K S values by perimer color scan. The colour fastness to washing rubbing dry and wet light and perspiration of aqueous dyed fabrics were tested according to ISO standards. Results showed that cotton dyed fabrics without mordant showed a shade of reddish brown while other mordants exhibited light to dark brown shades. The colour fastness to washing and perspiration were good except unmordanted fabric which showed moderate to good fastness to washing whereas colour fastness light and dry rubbing were excellent for all fabrics wet rubbing was good for all nine fabrics except unmordanted fabric which showed moderate to good fastness. Introduction Since time immemorial the usage of natural dyes have been an integral part of the human life and society to colour different textiles materials. In the nineteenth century synthetic dyes in view of their low cost large variety of shades superior colour fastness high dye ability and greater
