Our patented technology takes piles of trashed textiles that would otherwise be landfilled or burned and transforms them into brand-new premium-quality fibers for the textile industry. While we currently focus on using cotton-rich textiles, the beauty of our technology is that it can also turn other cellulose-rich materials – old newspapers, used cardboard, crop residues like rice or wheat straw – into the same fantastic fiber.
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, proven and available for licensing. We’re also boosting our own capacity and preparing to build a commercial scale factory in Finland. We’re excited to be working with like-minded partners to make textile circularity an everyday reality.
A wide range of cellulose-rich materials can be used as feedstock. These include cotton-rich textile waste, used cardboard, paper, and wheat or rice straw.
Our process feeds on cellulose, but can handle blended post-consumer fabrics that contain materials like polyester and elastane.
No carbon disulfide
Our process creates a unique new cellulosic fiber through responsible chemistry that doesn’t use carbon disulfide (CS2).
Round and round we go.
Textile waste goes in. Unique soft fibers that look and feel like cotton come out. The history and the non-cellulosic particles in the feedstock – think polyester, elastane and dyes – are cleaned out in the process to create our regenerated textile fiber Infinna™.

Collection and sorting
Textile waste is collected and sorted by type. For us, the most valuable textiles have a high cotton content.
Non-fibrous materials like buttons, zippers and so on are removed, and the textiles are mechanically disintegrated to fine shreds.
The cellulose is captured and separated from non-cellulosic particles like polyester and dyes.
The cellulose is 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. From this point on material originating from the different feedstock types can be mixed.
Dissolving and wet-spinning
The cellulose powder is turned into a honey-like liquid and impurities are filtered out. New fiber filaments are born when the cellulose crystallizes during the wet spinning process.
The fiber filament is cut, washed and dried. The regenerated cellulose carbamate staple fiber – Infinna™ – is ready for the next phase in the textile manufacturing supply chain.
The Infinna™ staple fibers are delivered to yarn spinners or nonwovens manufacturers to be made into products like clothing and home textiles, or wipes and diapers.
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.

How the textile magic happens.
The magic in our process happens when urea reacts with 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™ is a circular and more sustainable option to conventional textile fibers like cotton, polyester and viscose. Best of all, Infinna™ is extremely versatile and has been demonstrated to work in the existing manufacturing supply chain. This means its processability is great and the potential applications are endless.
Future-proof your business.
It’s coming – a future where recycled and regenerated 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 unique, 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 regenerated Infinna™ textile fiber your customers want.
Our chemistry conforms to the ZDHC and MRSL and the whole process has been carefully designed to be safe, eliminate waste, and preserve resources.
Replace resource-heavy new raw materials that tax biodiversity 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 raw material options give you the flexibility to optimize your production according to the need, price and availability of raw materials in your market.
Our technology is made up of 3 distinct modules that can be located at a single facility or at multiple sites. This opens up possibilities for various new-builds as well as retrofitting opportunities at e.g. existing pulp and viscose lines.
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.
