Researchers from Harvard University have developed a biodegradable and sustainable wool-like fabric tech with pre-programmed shape memory, allowing the material to modify and hold a certain shape on command. The shape-shifting fabric is made by extracting keratin from recycled wool, since keratin is a flexible bioactive polymer that can be used for advanced applications. This research could possibly enable brands to reimagine how they use materials, textiles, and textiles when putting on collections, such as leather, and dairy farms.
