DYEING OF SILK YARN WITH EXTRACT FROM OLD LEAVES OF ARTOCARPUS HETEROPHYLLUS

Abstract

Jackfruit leaves are a renewable resource where there are frequently removed from the tree. However, its ability in utilising for natural coloration is beyond potential. In this research, old leaves from Jackfruits (Artocarpus Heterophyllus) was studied to uncover the dyeing capabilities on silk yarn. The modern extraction method through micro-wave oven was applied in three procedures pre mordanting and dyeing, simultaneous mordanting, and post mordanting. The established natural colours have been studies on its dyeing ability on silk yarn by using aluminium sulphate and tannin as the mordant. Through visual observation, it was discovered that the shade of colour from Pre-mordanting and dyeing showed excellent results in the range of dark-brown colour. The lightest shade appeared through Post mordanting and dyeing where Simultaneous mordanting and control samples showed a similar range of mid-brown colour. Therefore, the application of renewable resources such as the Jackfruit leaves will become a matter of significant importance for the establishment of safe and eco local textile products.
