Keel Labs is a sustainable materials company that develops innovative materials derived from ocean resources. The main product, Kelsun™ fiber, uses seaweed due to its versatility, resilience, and ecological benefits. The production process involves extracting alginate, a biopolymer from seaweed, and combining it with proprietary additives and water to form a solution known as dope. This solution undergoes wet spinning, where polymer chains link to form fine filaments, which are then extruded into an aqueous solution and stretched to align their internal structure. The filaments are rinsed, finished, dried, and processed into stable fibers ready for spinning into yarns. Kelsun™ fiber can be blended with cotton or hemp fibers and integrated into existing yarn and textile production systems. As a USDA-Certified Biobased Product, Kelsun™ offers a sustainable alternative for the textile industry, enhancing environmental benefits while maintaining compatibility with current manufacturing processes.
