Colorifix dyeing technology uses a bio-based process to grow, deposit and fix colour onto textile. A colour target provides the reference for online DNA sequencing, which is inserted into a non-pathogenic microbe. Using renewable feedstocks such as sugars, yeasts, and plant by-products, they grow these genetically modified microorganisms to produce the desired colour. It is transferred onto textiles and fibres using conventional dyeing equipment, but with zero harmful substances and a fraction of the water and energy necessary in conventional dyeing. Since its founding in 2016, they have bought many colours to market including indigos, mauves, pastels and beiges. Image Colorifix.
