Pipes running from some apparel factories in China—and Bangladesh and Indonesia and other countries that feed American fast fashion habits—dump red and blue and green wastewater into local streams and rivers. Downstream, people drink the water and eat fish that have been living in it. Some brands are working with factories to limit how much dye goes down drains and keep some of the 3, chemicals used in the industry out of waterways.
But a handful of designers are questioning whether we need to use those chemicals at all, and experimenting with coloring fabric with microbes instead. In her lab, Chieza works with Streptomyces coelicolor , a bacteria that produces pigment as it grows during its week-long life. With synthetic biology, Chieza says, it will be possible to program the organism to produce an even fuller range of colors. The whole process uses significantly less water than typical industrial dyeing.
Bacterial pigment is biodegradable, but designers still plan to avoid dumping it into water. The technology is still at an early stage. Living Colour is beginning to collaborate with small brands and independent designers, but says that working at a larger scale will require more development.
We are working with scientists to test if our way of working can be scaled. The structure of the clothing industry, and fast fashion in particular, makes it difficult to change industrial processes. Companies tend to be focused on finding the cheapest way to make clothes, not developing technology.
The industry recognizes that it has a problem both with the chemicals and solvents used in dye and the amount of water that is used. Some companies have pioneered other solutions; a Dutch company called DyeCoo , for example, uses CO2 to dye fabric instead of water, in a closed-loop system with no waste. Now, Chieza says, some in the industry are beginning to consider bacteria as a new solution.
Bioengineering—using bacteria, algae, animal cells, or fungi—can also be used to make fabric itself. Modern Meadow, one startup, makes leather from lab-grown collagen. These processes could be combined with pigment-producing bacteria. Events Innovation Festival The Grill. Follow us:. By Adele Peters 4 minute Read. Design Co.

Azo dyes are synthetic dyes used in a variety of consumer goods including foods, cosmetics, carpets, clothes, leather and textiles. A small proportion of azo dyes contain, or can break down to form, aromatic amines. Aromatic amines can migrate from clothing and leather articles and be absorbed through the skin where there is direct and prolonged contact. The amount of aromatic amines released can increase with body heat, sweat and saliva. The ACCC tested a range clothing and manchester for hazardous aromatic amines in and Where items were found to contain aromatic amines above the acceptable limit, the suppliers removed the product from the market. The available evidence indicates that the use of problematic azo dyes isn't widespread.

Solvent dyes are dyes that are soluble in organic solvents and usually used as solution in organic solvents. Solvent dyes can be found in azo, disperse, cationic dyes. Solvent dyes are essentially insoluble in water but are soluble in different types of organic solvents. Solvent dyes are used to color organic solvents, hydrocarbon fuels, waxes, lubricants, plastics, and other non-polar materials based on hydrocarbons. Industrial use : Solvent dyes can be applied to the coloration of products in the mineral oil industry, plastics industry and wax industry.
