Next-generation fiber producer Everbloom has announced that the U.S. Federal Trade Commission (FTC) has approved Renoa, a new regenerated fiber made from keratin-rich textile waste. The decision establishes Renoa as a separate fiber category and allows textile products containing the material to be labelled and sold in the United States.

Developed at Everbloom’s laboratory in New York City, Renoa is described as the first fiber regenerated from keratin-rich textile waste and offcuts, including down. Produced in the United States using domestic resources, the material is designed to offer a soft feel, breathability and appearance similar to cashmere and wool, while providing improved durability and longer use.

The FTC approval is a major regulatory step for Everbloom and represents a new development in the textile industry. While many new fabrics and blends have entered the market, establishing a new FTC-recognised apparel fiber category requires companies to show that the material is fundamentally different from existing fibers through a detailed regulatory review.

The technology behind renoa is Braid.AI, Everbloom’s proprietary artificial intelligence platform. It combines predictive modelling with thermoplastic protein engineering to improve the conversion of keratin-rich proteins into performance fibers. The system predicts important properties such as softness, strength, texture and dyeability before production, helping the company speed up material development and improve consistency and control during manufacturing.

Braid.AI is designed to predict how different protein sources will behave during production, allowing Everbloom to adjust manufacturing conditions before production begins. According to the company, this has reduced the development process from around two months of laboratory testing to approximately two weeks.
