New “renoa” Fiber Promises Washable Cashmere Feel as First U.S. Fiber Classification in 25 Years
A startup’s waste‑derived fiber mimics cashmere’s softness while being machine‑washable and eco‑friendly.
From Waste to Luxury‑Feel Fiber
Cashmere has become ubiquitous across fashion, appearing in items ranging from high‑priced cable‑knit cardigans to budget crewnecks, and even in running shirts. Yet the material remains costly, delicate to care for, and linked to environmental concerns such as rangeland damage caused by goats.
Enter renoa, a newly developed fiber that seeks to deliver the cashmere experience without its drawbacks. The fiber is produced by a startup called Everbloom, which transforms waste protein sources—including cashmere and wool scraps as well as down and feather “lint” from the bedding industry—into a powder. This powder is combined with a biodegradable biopolymer, then extruded to match the length and diameter of specific natural fibers.
Regulatory Milestone
Renoa has earned the distinction of being the first new fiber classification approved by the U.S. Federal Trade Commission in a quarter‑century, marking a rare regulatory update for textile labeling.
Development and Testing
Everbloom spent several years developing the fiber, employing its own AI model for material science. The company’s co‑founder and CEO, Sim Gulati, demonstrated a range of renoa products during a visit to the firm’s New York City headquarters, located fifteen floors above Fifth Avenue near Bryant Park. Samples included a crewneck sweater, knit gloves and a scarf.
The sweater and gloves felt soft and lightweight. The scarf, a custom test piece, had endured repeated washing and tumble‑drying without pilling, shrinking or losing its shape, according to Gulati.
Path to Market
Everbloom is collaborating with several brands to introduce renoa into consumer goods. Initial offerings are expected to feature renoa as a blended component, comprising roughly a fifth of the material in items such as cashmere sweaters. Gulati indicated that the first market‑ready product should appear in the second quarter of 2027.
In blended form, the 80/20 cashmere‑renoa mix felt remarkably close to pure cashmere, and Gulati suggested that standard commercial finishing processes could further mask any residual differences while preserving washability and stability.
Implications for the Industry
If renoa reaches shelves as anticipated, it could broaden access to cashmere‑like comfort while reducing reliance on newly harvested fibers and mitigating associated environmental impacts. The development also highlights a growing trend of leveraging waste streams and advanced material‑science tools to create sustainable alternatives in fashion.
Renoa may signal a shift toward more responsible luxury, marrying softness with sustainability.
