Sweater knitted with a plant-based biopolymer

Swatches | February 1, 2021 | By:

Japanese technical apparel brand Goldwin Inc. and biomaterial innovator Spiber Inc. have created what the companies call the world’s first knitted garment made with Brewed Protein, a biopolymer created from a plant-based microbial fermentation process. Named simply “The Sweater,” it is the partnership’s first Brewed Protein garment brought to market in the U.S. It was designed to emulate a traditional ski sweater, with low-gauge knit and twisted yarn for a soft and comfortable feel. The companies say the product is a milestone in their shared mission to reduce the fashion industry’s impact on the environment by replacing traditional, petrochemical-based materials and production methods with innovative, biobased solutions.
