Our patented technology takes piles of cellulose-rich waste that would otherwise be landfilled or burned – old textiles, used cardboard, crop residues like rice or wheat straw, and more – and transforms them into premium-quality superfibers for the textile industry.
We break waste down and capture its value at the polymer level, giving it new life as Infinna™ – the unique textile fiber that looks and feels like cotton and is known scientifically as cellulose carbamate fiber.
Our technology is ready and proven, and we’re excited to work with like-minded partners to scale it and make textile circularity a reality.
Wide range of cellulose-rich materials – like cotton-rich textile waste, cardboard, paper, or wheat or rice straw – can be used as feedstock.
Process can handle impurities like polyester and elastane.
No carbon disulfide
Gives viscose factories a new fiber and a safer process by getting rid of CS2.
Textile waste recycling is becoming mandatory in the EU in 2025 and we want to be involved in developing new bio-based fibers from this waste. We see substantial opportunities in this.

Round and round we go.
Textile waste goes in. Unique soft fibers that look and feel like cotton come out. The history and any non-cellulosic particles in the feedstock – think polyester, elastane and dyes – are cleaned out in our process to create our superfiber Infinna™.
Collection and sorting
Textile waste is collected and sorted by type.
Non-fibrous materials like buttons, zippers and so on are removed, and the textiles are disintegrated to fine shreds.
The cellulose-based fibers are separated from fibers like polyester and elastane.
The cellulose fibers are activated with urea and a stable, dissolvable cellulose carbamate powder is born. Whether initially a t-shirt, cardboard or rice straw, the raw material turns into the same powder, and from this point on they can be mixed.
Dissolving and wet-spinning
The cellulose powder is turned into a honey-like liquid and impurities are filtered out. The new fiber filaments are born when the cellulose crystallizes during the wet spinning process.
Cellulose carbamate fiber
The fiber filament is cut, washed and dried and the high-quality, cellulose carbamate staple fibers – Infinna™ – are ready for the next phase in the textile manufacturing supply chain.
The staple fibers are delivered to yarn spinners or nonwovens manufacturers to be made into products like clothing and home textiles, or wipes and diapers.
How the textile magic happens.
The magic in our process happens when urea reacts with the cellulose, creating a carbamate functionality that gives the new fiber unique qualities like its soft and natural look and feel, superior dye uptake, and naturally occurring antimicrobial properties. Infinna™ truly is a real and more sustainable option to conventional cotton, polyester and viscose. And best of all, the fiber is extremely versatile and has been proven to work beautifully in the manufacturing supply chain, which means the potential applications are endless.
Future-proof your business.
It’s coming – a future where circular textiles replace those made with new resources. Why? Because it’s what people and brands want, and it’s what the planet needs. That means it’s also the future of your business. And we’ll help you get there.
New premium product
Enhance your existing product portfolio with Infinna™ – a new, sustainable, and in-demand premium textile fiber that looks and feels like cotton and is as versatile.
Our technology covers all steps – from the pre-treatment of the raw material to the finished, ready-to-ship, premium Infinna™ textile fibers your customers want.
Our process uses animal feed grade urea to prepare the cellulose to be wet-spun into new fibers. No need for the toxic carbon disulfide used in viscose manufacturing. Our chemistry conforms to the ZDHC and MRSL.
Replace resource-heavy new raw materials with cellulose-rich feedstock that’s already in use, like old clothes, cardboard or paper. Keep biomass in circulation and leave the land for food crops and wilderness.
Multiple feedstock options give you the flexibility to optimize your production according to the need, price and availability of raw materials in your market.
Our technology can be retrofitted cost-effectively to any pulp and viscose fiber lines in existing factories.
We’re in this together.
Decades of engineering, research and development have brought Infinited Fiber to where we are today: ready for our technology to help you meet the growing demand for high-quality regenerated textile fibers.
Real change will happen when we work together. That’s why we offer our partners a simple turnkey factory concept that enables fast access to a new market with limited investment. We offer our know-how, clear blueprints and access to top-notch engineering partners to enable the safe delivery and installation of our technology.
