Frequently asked questions.
What is Infinited Fiber Company?
Infinited Fiber Company is a Finnish biotech with a patented technology to create premium-quality textile fibers out of cellulose-rich waste that would otherwise be landfilled or burned. This means anything from discarded jeans and cotton T-shirts to used cardboard, or even agricultural byproducts like rice or wheat straw. The result is always the same superfiber with the natural look and feel of cotton. On the label it’s cellulose carbamate, but you can also call it Infinna™.
What’s Infinna™? And what’s cellulose carbamate?
Infinna™ is the new brand name for our cellulose carbamate fiber, the unique textile fiber we currently make from 100% post-consumer textile waste. In the future, the raw material for Infinna™ may come from other cellulose-rich waste streams, like cardboard. Infinna™ looks and feels soft and natural like cotton, but has its own character and properties. It works beautifully on its own for 100% regenerated textiles and blends easily with other textile fibers.
How is Infinna™ different from other textile fibers?
First and foremost, it comes from a great place! The raw material is waste, so nothing new needs to be cultivated or cut down to create Infinna™. It looks and feels soft and natural, and because it’s made from cellulose, it is completely biodegradable and doesn’t contain any microplastics. It has superior dye uptake compared to cotton and viscose as well as naturally occurring antimicrobial properties.
What kinds of textiles can be made with Infinna™?
The fashion textile applications we’ve tried and tested are denim, single jersey, French terry, and lightweight wovens like shirting fabrics. We love all these fabrics! And as our journey is only beginning, we’re confident even more textile types will follow. We’ve also tested Infinna™’s suitability for nonwoven applications (think wipes, diapers, soft hygiene products), and see lots of potential in this industry going forward.
What makes Infinna™ an environmentally friendly choice?
The raw material for starters: Infinna™ is made from 100% waste that would otherwise be burned or landfilled with detrimental impact on air, water and land quality. Nothing new needs to be grown when we capture the value of what’s already in circulation, meaning land is preserved for other uses – including food crop cultivation and wilderness. Producing Infinna™ uses a fraction of the water needed to grow conventional cotton. Our process is based on responsible chemistry: no organic solvents are needed as we’ve replaced the toxic carbon disulfide used in viscose production with animal feed grade urea. Infinna™ is biodegradable, contains no microplastics, and can be recycled together with other textile waste when it reaches the end of its life.
Most clothes contain a blend of textile fibers. Is mixed textile waste a problem for your technology?
Yes and no. Recycling mixed textiles is always more difficult than recycling textiles made from a single material and designed with recycling in mind from the start. Our technology is robust and non-cellulosic textile fibers can be removed without disruption to the process. But because our fibers only use the cellulose in the raw material, all the polyester, elastane and other non-cellulosic materials need to be removed. The higher the cellulose content of the raw material, the more efficient our process. That’s why our preference is for at least 80% of the textile feedstock to be cotton.
This sounds exciting! I want to take part by sending you my old clothes for recycling. What should I do?
We’re happy to hear you’re with us! The best way for you to get involved is to take your worn-beyond-repair clothes to your nearest textile collection point. This way they will be delivered to the right place to be repaired, recycled or regenerated. Unfortunately we cannot accept textile donations from individuals – we also work with official suppliers and sorters.
Where can I buy yarns, fabrics, clothes and other textiles made with Infinna™?
We work with amazing manufacturing partners and global brands, and there are limited edition clothing collections coming to retail in 2021. We are working on boosting production capacity so that items made with Infinna™ become more widely available. Unfortunately, at the moment we cannot supply individual people or organizations with yarns or fabrics even though we’d love for you to get your hands on these.
This technology sounds like something I want to be involved in scaling up. What should I do?
We’re happy to hear! We have technology licensing packages and blueprints for different scenarios to scale and make this technology widely available. For example, if you already operate a viscose or pulp factory, retrofitting some of your lines with cellulose carbamate technology might be an option. If you’re thinking of setting up something completely new, we have a blueprint for that, too, mapping out the space, equipment and logistics needed to get going. We’d would love to discuss the details with you, so please get in touch using the contact form on this site.
