【 摘 要 】
The natural dyes play a prominent role in maintaining the sustainability of any ecosystem due to their eco-friendly characteristics and relative non-toxicity over synthetic dyes. The aim of the present study was to investigate the possible dyeing capacity of the natural dye extracted from leaves of Juglans regia in association with mordant obtained from wood of Salix alba). The efficiency of the dye extraction was tested on wool, pashmina, cotton and silk by pre, instantaneous and post mordanting methods. The quality of the dye and the mordant observed to be the highest (28.88%) for pashmina and lowest for cotton (15.21%). Colour strength and coordinates exhibited the highest (0.886) for pashmina, followed by wool (0.761) and the lowest (0.718) for silk. Fastness grades of all the tested samples observed were mostly good to excellent. The dyed fabrics appeared with great light and dark brown with varying shades, efficacy and retention grades. However, cotton showed no affinity for the dye and mordant. The intermixing of natural dye with mordant in different mordanting methods illuminated their colour qualities with efficacy on tested fabrics. The study revealed that the dyeing ability of J. regia and mordant extracted from S. alba can be utilized commercially for industrial exploration.
