Dyeing and Fastness Properties of Natural Dyes Extracted from Eucalyptus Leaves Using Padding Techniques

A natural dye extracted from eucalyptus leaves was applied to a silk and wool fabric by the use of two padding techniques, namely the pad-batch and pad-dry techniques under different conditions. Silk and wool fabrics dyed in a solution composed of eucalyptus extract from leaves showed a shade of pale yellow to brown. The exception was when the fabric was dyed with ferrous mordant, resulting in a shade of dark grayish-brown. The fastness properties ranged from good to excellent, while light fastness was fair to good.
