Brands launch sustainable collection with Spiber’s Brewed Protein fiber

Leading Japanese apparel brands Goldwin, The North Face Japan, and Neutralworks have unveiled the Utopian Uniform Collection, featuring garments made with Spiber’s innovative Brewed Protein fiber. This cutting-edge material, developed by Spiber, a company based in Yamagata, Japan, is derived from plant biomass through a proprietary fermentation process.

Brewed Protein materials can be tailored to mimic various properties, offering delicate filament fibers with a silky sheen or spun yarns that provide cashmere-like softness, wool-like thermal insulation, and moisture-wicking capabilities. The process has a significantly lower environmental footprint, reducing harm to marine ecosystems compared to traditional plastics and cutting greenhouse gas emissions commonly linked to animal fibers.

The collection highlights sustainable craftsmanship through the use of advanced knitting and design technologies. Goldwin introduced a crew neck knit pullover and cardigan, manufactured using Shima Seiki’s seamless WholeGarment process. This 15-gauge jersey knit ensures comfort and mobility, featuring a unique garter weave design accent along the shoulders and sides.

The North Face presented a crew neck sweater and hoodie, created with the Globefit WholeGarment manufacturing method. This technique captures the three-dimensional silhouette of the human body, ensuring optimal comfort for both movement and stillness.

Neutralworks added a shell outerwork anorak, designed as part of the Syn-Grid project by Goldwin and Synflux, a Tokyo-based fashion laboratory. The design integrates AI algorithms and 3D technology to minimize material waste during the cutting process.

This collaboration exemplifies a commitment to sustainability and innovation in the apparel industry. By utilizing Brewed Protein fibers and advanced production methods, the Utopian Uniform Collection combines eco-friendly materials with functionality and aesthetic appeal, marking a significant step toward environmentally responsible fashion.
