The leaves and bark that are by products of the responsibly farmed eucalyptus used in the manufacture of lyocell fibres were extracted with water to provide a source of natural colour. Lyocell fabric, which required minimal preparation, was screen printed with an aqueous paste containing only the extracted colour and a natural thickener to provide attractive golden-yellow prints. The printed fabrics demonstrated surprisingly good fastness towards light, washing and rubbing. A mordanting pretreatment of the lyocell with alum modified the colour of the naturally coloured prints to become stronger and duller, but provided no advantage in terms of technical performance. The outcome presents a potentially useful model for the development of sustainably coloured fashion textile products.
