Another technology that’s permanently changed the industry is the use of ozone in laundry machines
Ozone is a revolutionary technology,” says Alice Tonello. “It realises bleach effects on denim with a drastic reduction of water consumption and elimination of all hazardous chemicals.”
The ozone is dissolved in water in the laundry machine and removes the indigo during the wash cycle. It’s an eco-friendly way of bleaching that minimises health risks for the operators.
It’s already a consolidated technology, and the latest iteration of the machinery, like Tonello’s ECOfree 2, allows the ozone to function in both water and air.
