Source and geography

Infinna is the fiber brand of Infinited Fiber Company, a Finnish technology company. Its feedstock is cellulose-rich textile waste, mainly cotton-rich post-consumer textiles, and the fiber is a regenerated cellulose made via cellulose carbamate. The company has planned a first commercial factory of about 30,000 tonnes per year at Stora Enso's former Veitsiluoto paper-mill site in Kemi, Finland, an investment of around 400 million euros. As of a March 2026 report it had an environmental permit but no final investment decision.

Worth knowing

• Infinna's chemistry swaps the carbon disulfide of viscose for urea, forming cellulose carbamate that dissolves in dilute alkali.
• The planned Kemi factory would reuse the site of a closed paper mill in Finnish Lapland.

Types, grades and fabrics

Types and grades

Infinna is marketed as a single staple fiber made from recycled textile waste by the cellulose carbamate route, rather than as a family of grades. The producer presents it as a cotton-like fiber for spinning in blends or alone. What varies between batches is the feedstock history (mostly cotton-rich post-consumer textiles) and the cut length and fineness chosen for a spinning system; these should be confirmed with the company for any order. Treat Infinna as a pre-commercial material until the Kemi factory is built.

Fabrics and products

Infinna is intended for cotton-like apparel uses, where it can be spun alone or blended with cotton, lyocell or other fibers. Because the fiber is regenerated cellulose, it spins on standard staple systems and dyes with cellulose dye classes, so mills can treat it much like viscose or lyocell staple. Volumes so far have come from pilot output, so finished products have been small collections rather than mainstream lines, and the percentage of Infinna in each item should be read from the label.

Buying and care

How to judge quality

Expect small volumes and premium pricing, because commercial production awaits the Kemi factory investment decision. The content label should list a generic fiber name; since the regulatory name for a carbamate fiber could not be confirmed for this atlas, ask the brand which name it used and why. Recycled-content claims should come with documentation such as transaction certificates under a recycled-content chain-of-custody standard. Ask for test data on tensile strength, pilling and colorfastness for the actual fabric. Judge the fabric as you would a viscose or lyocell blend: even surface, stable dimensions after washing, and clean seams.

Care in detail

Care is expected to follow viscose-type regenerated cellulose and the blend partner. Wash cool (30 C) on a gentle cycle with mild detergent, turn garments inside out, and avoid wringing, since regenerated cellulose is typically weaker wet than dry. Dry flat or on a hanger, or tumble on low only if the label allows. Iron on a medium setting (about 150 C) while slightly damp. Avoid chlorine bleach and store dry to prevent mildew. For denim blends, wash sparingly and inside out to limit abrasion and fading. The garment label takes precedence, since independent care testing is limited.

Care at a glance

Follow the finished product’s care label. A trademark does not specify the care needs of every blend or construction.

Environmental and social footprint

Infinited Fiber's case rests on replacing virgin cotton or wood pulp with textile waste, and on a chemistry based on urea and alkali rather than carbon disulfide; the company's life-cycle figures are producer claims and no independent peer-reviewed assessment specific to Infinna was found for this entry. The environmental balance will depend on the energy source at Kemi, the yield from mixed textile waste, and what happens to the separated polyester and other residues. General evidence favors cellulose over plastic at end of life: in a 2019 study (Zambrano and colleagues), rayon microfibers biodegraded in aerobic aquatic tests while polyester microfibers persisted. Recycled-content marketing in the US is subject to the FTC Green Guides, which expect claims to be specific and substantiated.

Tradeoffs

Producer claims apply to defined products and comparisons. This atlas does not independently certify performance, sourcing or environmental claims.

Science

Manufactured cellulose family

Regenerated cellulose or a cellulose derivative, depending on the fiber.

Structure and chemistry

The finished fiber is regenerated cellulose. The key intermediate is cellulose carbamate, a cellulose derivative in which some hydroxyl groups carry carbamate (O-CO-NH2) groups formed by reaction with urea. The carbamate groups make the cellulose soluble in dilute alkali; after spinning, the regenerated fiber is essentially cellulose with a low residual carbamate content. The producer describes a cotton-like appearance, and its FAQ states claims such as good dye uptake. Independent structural data on crystallinity and cross-section are limited.

From source to yarn

Infinited Fiber describes the route this way: textile waste is collected, sorted and shredded; non-cellulosic fibers such as polyester and elastane, dyes and finishes are removed; the recovered cellulose is activated and reacted with urea to form cellulose carbamate; the carbamate is dissolved in alkali to form a spinning solution; the solution is wet-spun into a coagulation bath, and the filaments are washed, dried and cut to staple. The approach adapts older carbamate research as an alternative to carbon disulfide-based viscose chemistry.

Performance in use

Publicly available independent test data remain limited. As a regenerated cellulose it should absorb water readily, char rather than melt, and dye with reactive, direct and vat dyes. Infinited Fiber claims the fiber has a natural cotton-like look, good dye uptake and some antimicrobial properties, and that it is biodegradable and free of microplastics; these are producer statements whose test conditions should be requested. Strength and abrasion performance in finished fabrics depend on blend and yarn construction.

How it is identified

Burn tests (indicative only) should show cellulose behavior: rapid burning, paper-like odor, little ash. FTIR identifies cellulose; residual carbamate nitrogen may be detectable by elemental analysis, but no standard public method identifies the brand. The atlas links Infinna to viscose as the nearest generic family, but the fiber is not made by the viscose process, so product labels may use a different name. Check the actual label and producer guidance.

History

Timeline

1. 2022Infinited Fiber chose the site of Stora Enso's closed Veitsiluoto paper mill in Kemi, Finland, for a planned factory of about 30,000 tonnes a year and an investment of around 400 million euros. [1]
2. 2026A March report stated that the Kemi project had received its environmental permit but that no final investment decision had been made. [2]

Infinna developed as part of efforts to return cellulose-rich textile waste to fiber production. Pilot work, planned capacity and actual commercial supply are different milestones.

The deeper record

Infinited Fiber grew out of Finnish research on cellulose carbamate, a chemistry studied for decades as a viscose alternative, and set out to apply it to textile waste. In 2022 it chose Kemi for a first commercial factory. Trade press has reported funding of about 40 million euros backed in part by the parent companies of Zara, Uniqlo and H&M. Delivery dates have shifted, and by March 2026 the Kemi project had its environmental permit while the investment decision was still pending.

Labeling and law

Infinna is a trademark, not a generic name. Under the FTC rules (16 CFR 303.7) rayon covers regenerated cellulose, and the EU list in Regulation (EU) No 1007/2011 distinguishes viscose, modal, lyocell and cupro by process; which name a carbamate fiber should carry could not be confirmed for this entry. Buyers should follow the producer's labeling guidance and verify recycled-content claims through documentation for the specific lot.

This describes what rules and standards cover. It is not legal advice; jurisdiction, product form and current rule text control.

Frequently asked

What is Infinna made from?

Cotton-rich textile waste, mainly discarded clothing. The cellulose is recovered, reacted with urea to form cellulose carbamate, dissolved in alkali and spun into new fiber, according to Infinited Fiber Company.

Is Infinna the same as viscose?

It is also regenerated cellulose, but it is not made by the viscose process, which uses carbon disulfide. The carbamate route is different chemistry. The name used on a US or EU content label should be confirmed with the brand.

Can I buy Infinna clothes now?

Only in small quantities from pilot production. The company's planned Kemi factory of about 30,000 tonnes per year had an environmental permit but no final investment decision as of March 2026, so availability is limited.
