Italian fashion designer, Antonella Bellina, is creating sustainable fashion by converting the proteins from sour milk into a deluxe, silky fiber. Bellina wanted to bridge the gap between fashion and sustainability and was inspired one day while making a cup of coffee and finding sour milk.
Creating this eco-friendly t-shirt only requires half a gallon of milk and produces an ultra-soft garment. To transform the milk, the dairy should be heated to exactly 122 degrees Fahrenheit. Once heated, citric acid is combined to separate the protein from the milk. This allows the casein protein to be strained, then dried and ground into a powder. A final, secret step is then executed to produce a fiber that can be twisted into threads and woven into the material used to make the shirts.
With concerns over fast-fashion and climate change mounting, this eco-friendly fabric could be an intriguing new way to produce sustainable clothing.
