Italian mill to unveil 100% Brewed Protein yarn

Biotechnology company Spiber has announced a major milestone in its partnership with Italian spinner Botto Giuseppe with the launch of a new yarn collection made entirely from the Japanese firm’s Brewed Protein fibres.

Spiber’s Brewed Protein is made from plant-derived biomass, such as sugar cane and farm waste, using a proprietary fermentation process to produce polymers that can be transformed into a variety of forms, including textiles.
