The brave new world of 21st century bio-engineering could hold the key to keeping wool white in sunlight.
The Wool and Sheep Cooperative Research Centre is experimenting with a new nano-technology sun screen designed to protect wool from UV.
Unlike cotton or synthetics, wool tends to yellow when it’s being processed and after washing and wearing in daylight.
Program leader, David Tester says it’s possible to select for whiter wool and then prevent it from yellowing during processing and wearing.
“We’ve got our fingers crossed and hope that’s the case because if we can move both and more photo-stable then we may have a product that compete with cotton and polyester in this apparel area where our research is focused,” he says.
