Source and geography

SPINNOVA is the fiber brand and technology of Spinnova Plc, a Finnish company. The feedstock is cellulose, principally wood pulp, and the producer states that the technology can also use waste streams such as textile, leather or agricultural residues. Commercial scaling has been uneven: Spinnova's joint venture with the pulp producer Suzano, Woodspin Oy, was placed on hold, and in 2025 Spinnova bought Suzano's stake in Woodspin and in Suzano Finland for a nominal two euros, ending the joint-venture arrangement.

Advantages

  • Spinnova states the process uses no dissolving chemicals, forming fiber mechanically from microfibrillated cellulose.
  • The producer reports large reductions in water use and emissions compared with cotton in its own assessments.
  • The fiber keeps native cellulose I structure, a different route from viscose, lyocell or cupro.
  • Its feedstock range can in principle extend to waste streams, according to the company.

Drawbacks

  • Commercial scale is unproven; the Woodspin factory joint venture was halted in 2025.
  • Independent test data on strength, wet performance and durability are scarce.
  • It is almost always blended, so the environmental benefit per garment is diluted.
  • Regulatory labeling of this new fiber type is unsettled, which can confuse content labels.

Worth knowing

  • Spinnova fibers keep the native cellulose I crystal form because the cellulose is never dissolved, unlike viscose, lyocell and cupro.
  • A Finnish ski maker has published trials using SPINNOVA material as a reinforcement in place of fiberglass in ski composites.

Types, grades and fabrics

Types and grades

SPINNOVA is one fiber technology rather than a range of numbered grades. The standard product is a staple fiber made from wood pulp, and the producer has reported separate life-cycle results for fiber made from eucalyptus pulp. Spinnova also states that the same mechanical route can use waste streams, including leather, textile and agricultural residues, which would produce variants with different feedstock histories. Beyond apparel, the material has been tested in composites: a Finnish ski maker has published trials using SPINNOVA material in place of fiberglass. Because output volumes remain small and the Woodspin factory joint venture was put on hold, commercial availability should be checked before specifying it.

Fabrics and products

SPINNOVA fiber is blended with other fibers and spun into yarns for knitwear, T-shirts and other casual apparel shown in brand collaborations and limited collections. It is supplied as staple fiber for conventional spinning, usually as a blend component rather than as 100% SPINNOVA yarn. Composite applications, such as ski constructions, use the fiber as reinforcement in a resin matrix. Most consumer items have been capsule or collaboration products, so the blend ratio on the label is essential.

Buying and care

How to judge quality

Because SPINNOVA is normally a minority blend component, read the content label for its percentage, and note that no generic fiber name for it has been publicly confirmed, so labels may vary. Ask the brand which regulatory fiber name was used and on what basis. Performance claims should be backed by test reports for the actual yarn: tensile strength, abrasion (Martindale or similar), pilling and wash durability. Ask specifically for wet strength, since the fiber is held together by hydrogen bonds that water can loosen. Expect a premium price and small runs; mass-market pricing with 'SPINNOVA' claims warrants a documentation request.

Care in detail

Care is governed by the blend partner and the garment label. For cotton or lyocell blends, wash at 30 to 40 C on a gentle cycle with mild detergent, inside out, and avoid long, hot tumble drying. Because independent data on wet strength are limited, do not wring and avoid harsh mechanical washing; dry flat or on a hanger. Iron on a medium setting only if the label permits. Avoid chlorine bleach, which attacks cellulose. Store dry to prevent mildew, as with any cellulose fiber. If the garment includes recycled polyester, follow the lower heat limits for that component.

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

Spinnova's own life-cycle statements compare its fiber with cotton: the company has said its wood-pulp fiber has about a 65% lower carbon footprint and uses about 99% less water than cotton, and a later figure for eucalyptus-pulp fiber put greenhouse gas emissions about 74% below the global average for conventional cotton. Reported percentages vary with the cotton baseline chosen (irrigated versus global average) and the pulp source, so they should not be compared across studies without checking the functional unit, usually one tonne of fiber. No independent peer-reviewed life-cycle assessment was found for this entry. Impacts of pulp production, including forestry and energy, sit upstream and depend on the pulp supplier. End-of-life behavior should resemble other cellulose, but blends with polyester change that.

Science

Cellulose-rich plant material

Seed, stem, leaf or other plant structure. Extraction and preparation vary.

Structure and chemistry

SPINNOVA fiber is made of cellulose that has not been dissolved or regenerated. The producer describes the input as microfibrillated cellulose (MFC): pulp fibers mechanically broken down into a paste of fine cellulose fibrils. During spinning, these fibrils align with the flow and bond to one another by hydrogen bonding as the material dries, forming a fiber that is a network of native cellulose I fibrils rather than the cellulose II lattice found in viscose or lyocell. Public data on crystallinity, cross-section and dimensions are limited.

From source to yarn

Spinnova describes three main stages. First, pulp is mechanically refined into a fine microfibrillated cellulose suspension, without dissolving chemicals. Second, the suspension is pumped through a proprietary nozzle in which the fibrils rotate and orient along the flow, forming a continuous fiber. Third, the fiber is dried, with water evaporated rather than exchanged in a coagulation bath, and cut to staple for blending and spinning into yarn. The company states that the process creates no side streams and cites large water and CO2 reductions versus cotton; these are producer claims.

Performance in use

Detailed independent performance data remain scarce. The producer presents SPINNOVA as a cotton-like staple fiber that is normally blended with other fibers in yarns, which means the finished fabric's strength, moisture behavior and durability reflect the blend. As native cellulose, it is hydrophilic, chars rather than melts, and in principle accepts cellulose dye classes (reactive, direct, vat). Buyers should request test reports on the actual yarn, since strength of hydrogen-bonded fibril networks can differ markedly when wet.

How it is identified

Burn behavior should resemble other cellulose (paper-like odor, soft ash), but burn tests are indicative only. FTIR will identify cellulose, and X-ray diffraction could in principle distinguish its cellulose I structure from regenerated cellulose II, but no standard public method identifies the brand. Verification relies on supply-chain documents and the producer. The existing atlas base 'paper yarn' is an approximation: the fiber is not a cut paper strip.

History

Timeline

  1. 2025After a strategic review, operations of the Woodspin joint venture with Suzano were put on hold and Spinnova recognized an impairment of about 18.4 million euros on its Woodspin holding. [1]
  2. 2025In October Spinnova completed the purchase of Suzano's stakes in Woodspin Oy and Suzano Finland Oy for two euros, regaining unrestricted rights to license its technology. [2]

Spinnova’s development centers on turning a cellulose suspension into textile fiber. Commercial status and manufacturing capacity should be checked with the producer.

The deeper record

Spinnova was developed in Finland around the idea of forming textile fiber from cellulose mechanically rather than by dissolution. It then formed the Woodspin joint venture with the pulp producer Suzano to scale up production. In 2025, after a strategic review, Woodspin's operations were put on hold, Spinnova recognized an impairment of about 18.4 million euros on its Woodspin holding, withdrew financial guidance for 2025 and 2026, and acquired Suzano's stake for two euros, regaining the right to license its technology without restriction. Trade press later reported a textile-recycling consortium involving Spinnova and Circulose.

Labeling and law

SPINNOVA is a trademark, not a generic fiber name. How this mechanically formed cellulose fiber should be named under the FTC generic-name rules (16 CFR 303.7) and the EU fiber-name list in Regulation (EU) No 1007/2011 could not be confirmed from public sources for this entry. Buyers should follow the producer's current labeling guidance, check the finished label, and treat environmental comparisons as producer claims.

Frequently asked

What is SPINNOVA made of?

Cellulose, mostly from wood pulp. The pulp is mechanically refined into a paste of fine fibrils, which a nozzle aligns into a fiber that dries without a chemical coagulation bath, according to the company. It is not paper and not viscose.

Is SPINNOVA better for the environment than cotton?

The company reports much lower water use and emissions than cotton, around 99% less water and 65 to 74% lower emissions depending on the study and baseline. These are producer assessments; independent comparisons are not yet available, and garment-level benefit depends on blend share.

Can I buy SPINNOVA clothing?

Mostly through limited collaborations and capsule collections. Spinnova's planned large-scale factory joint venture was put on hold in 2025, so supply is small and availability varies. Check the content label for the percentage used.
