Stella McCartney continues the brand’s dedication to fashion eco innovation with the announcement of a new partnership with Bolt Threads, a San Fransisco-based biotechnology company creating the next generation of advanced materials. This new collaboration will push boundaries in fabric innovation and usher in the next generation of cutting-edge textiles.

Bolt Threads engineers fibers from scratch based on proteins found in nature, and then develops cleaner, closed-loop processes for manufacturing, using green chemistry practices.  Exemplified in the collaboration with Stella McCartney, Bolt Threads is able to create silk using yeast, making the textile vegan-friendly; staying true to the designer’s vegetarian philosophy. Solution oriented, this process reduces pollution, creates long-term sustainability, and always remains cruelty-free.

The material is the result of seven years of research and design in a lab. At the molecular level it is spider silk made by human hands. A big team of scientists, engineers, technicians and designers, have developed a way to closely mimic silk created in nature by producing a fiber from corn syrup that was fed to a yeast fermentation. Once the protein is harvested and purified into a powder, it is wet spun into fibres and twisted into yarns.

The first piece from the partnership will be a one-off gold dress made from Bolt Threads’ signature “spider silk”. It will feature in an upcoming exhibition at The Museum of Modern Art called Items: Is Fashion Modern?
