This new class of material is created using Spiber’s proprietary technology platform that enables customized design and molecular engineering of nature-inspired protein polymers. Brewed Protein materials are fibers, films, and other types of materials that are manufactured through fermentation (brewing) of plant-based ingredients.
These materials can offer alternative solutions to a wide range of conventional animal-based, plant-based and synthetic materials for various purposes, including textiles applications for the apparel industry.
Brewed Protein can be produced as filament yarns by extruding the polymers through nozzles. These filaments exhibit brilliant, silk-like luster and fineness. For staple fiber, the filaments that are cut into short, discrete lengths. The texture of the final material is greatly dependent on the fiber porosity and degree of twisting or entanglement of the staple fibers.
The staple fibers can be spun into yarn. By altering the protein content and diameter of the fiber, the feel of the yarn can be controlled, allowing for luxurious smoothness or a bulky, fleece-like touch.
Knit fabrics made from the filament or spun yarn are suitable for different uses and seasons. These include jersey or fleece used for T-shirts, hoodies, or bulky sweaters, providing a soft, comfortable texture.
Woven fabrics developed through weaving filament or spun yarns. By blending multiple materials or changing the weave structure and processing method, fabrics suitable for different uses and seasons can be made, from thin, tightly woven textiles to thick, insulative woolen ones. Woven denim fabric partially made from Brewed Protein fibers and replace existing materials allowing new approaches to denim recycling.
Brewed Protein fibers from biomaterial developer Spiber Inc., Yamagata/Japan, can also be used to produce materials such as fleece, fur alternatives and leather alternatives. The animal-free materials can have a realistic, long-haired fur-like texture. Furthermore, by modifying the surface treatment and interior structure of the material, a new range of tactile experiences, can be unlocked.
Spiber has established the technologies for replicating the process of protein evolution — which requires millions of years in nature — in the laboratory, where it can be achieved in a matter of years or even months.
