Kelsun

At the helm of material innovation.

About Kelsun

Kelsun™ fiber was created to supply the textile industry with a more sustainable alternative to conventional materials.

We start with a biopolymer that is extracted from seaweed. Seaweed is one of the most regenerative organisms on our planet and absorbs carbon dioxide in the ocean, similar to trees on land. We combine this with our proprietary formulation to create a solution that directly fits into existing, globalized textile infrastructure.

The end result is Kelsun, a bio-based fiber that can be used across the textile industry.

1

Seaweed & Harvesting

Our process starts with seaweed. We chose this raw material due to its versatility, resiliency, and wide-ranging ecological benefits. Seaweed is an active combatant against climate change, sequestering CO2 in the ocean as it grows. Seaweed does not require the use of arable land, pesticides, or fertilizers to grow, and is extraordinarily regenerative, making it the perfect starting point to address the climate impacts associated with standard textile production.

Biopolymer extraction & spinning solution prep

Our process continues with seaweed growers and processing partners across several coastal locations. The collected seaweed goes through an extraction process that separates the biopolymer that becomes the basis of Kelsun fibers. The extracted biopolymer is combined with proprietary additives and water to form a solution, called dope.

3

Fiber production (wet spinning)

At this stage, the process chemistry begins linking the polymer chains, forming thousands of fine filaments. These filaments are extruded into an aqueous solution and stretched to align their internal structure. A series of subsequent baths rinse and apply finish to the filaments prior to drying and spooling. The resulting material is then transformed into a staple fiber ready to begin the yarn spinning process.

Yarn production

Once Kelsun staple fiber is formed, it can be combined with other sustainable fibers, such as cotton or hemp. After blending, the staple fibers are drawn and spun into yarn that is ready for knitting or weaving!
