dyeing process

PILI is a biotech company that produces dyes and pigments using microorganisms for applications in textiles, inks, polymers, paints, and coatings. The technology uses microbial enzymes, which are re-engineered to produce brilliant and effective dyes from renewable resources. Enzymatic synthesis allows microbes to create materials sustainably by saving energy and reducing waste without significant inputs of toxic reagents. Once enzymatic cascades are designed, large-scale production begins without toxic inputs or harmful byproducts.

Safe and sustainable structural colorants free of toxic pigments and dyes developed by Cypris Materials. The technology behind Cypris’ colorants was inspired by how animals naturally exhibit vibrant colors via the reflection of certain wavelengths of light off biological nanostructures with precise physical spacing. Cypris develops self-assembling brush block copolymers through ruthenium catalysis. Using the same physics as the RGB on our computers, Cypris produces the entire rainbow of colors.

Bio-FREED™ is a one-step, foam-based dyeing process powered by Modern Meadow's application platform Bio-Alloy™. The technology combines proteins with bio-based polymers to create a molecularly mixed, miscible blend with unique functionalities and performances, significantly reducing carbon emission footprint by eliminating inefficiencies in the dyeing process in the textile industry. Compared to traditional three-step methods, this technology reduces up to 95% of water use and 80% of dyes applied, decreases energy use by 67%, and can be applied to any stage of textile production.
