What Is Algae / Seaweed Fiber?
Algae and seaweed fibre is a bio-based textile that incorporates content from fast-growing algae or seaweed, which can be cultivated without farmland, freshwater or fertiliser and even helps absorb carbon as it grows. Building fibre content from such a regenerative marine input is central to its low-impact story. The resulting fabric is soft and breathable. For a deeper introduction, read our material guides.
How Is Algae / Seaweed Fiber Made?
Harvested algae or seaweed is dried and processed into a fine biomass, which is incorporated into a cellulosic spinning solution and extruded into fibre, or blended into other regenerated fibres. The fibre is spun into yarn and knitted or woven into fabric, carrying a share of marine-sourced, renewable content.
Why Brands Choose Algae / Seaweed Fiber

- Carbon-absorbing feedstock: captures CO2 during cultivation.
- Versatile applications: usable as fibre, foam content or coating.
