Abstract
This research is concerned with natural dye extraction from the leaves of eucalyptus and the application of this dye for wool fabric dyeing using two padding techniques, namely the pad-batch and pad-dry techniques under different conditions. It was observed that with an increase in the dye concentration, the ultraviolet (UV) protection factor (UPF) values ranged between very good and excellent for wool fabric. The colour fastness to light and rubbing after dyeing the wool fabric treated with the mordant was investigated, the results of which showed fair to good fastness, whereas the colour fastness to washing was a good to very good level. The results confirmed that natural dye from eucalyptus leaf extract have potential applications for fabric dyeing and producing UV protective wool fabric.
