Environmental Impact
High Environmental ImpactThe viscose production process is one of the most chemically intensive in textile manufacturing. Carbon disulphide is a toxic solvent with significant environmental and worker safety implications. Deforestation is a documented concern — some viscose has been traced to ancient Indonesian or Brazilian forests. The CANOPY initiative audits viscose producers for forest sourcing.
Editorial Notes
Viscose is the third-most widely used textile fibre globally after polyester and cotton. Despite being plant-derived, its production process raises serious environmental concerns. The TENCEL and Modal variants use modified processes with greater chemical recovery. For the most sustainable cellulosic option, TENCEL Lyocell (closed-loop solvent process, wood traceability) is significantly preferable to standard viscose.
In depth
How Viscose Is Made
Viscose is a regenerated cellulose fiber: it starts as a natural plant material and is converted into a textile fiber through an industrial chemical process. Production begins with wood pulp, typically from beech, eucalyptus, pine, or bamboo. The pulp is treated with sodium hydroxide and then reacted with carbon disulfide to produce cellulose xanthate, which is dissolved into a thick, honey-like liquid — the "viscose" that gives the fiber its European name.
This solution is forced through spinnerets, devices with fine holes similar to a showerhead, into an acid bath. The acid regenerates the cellulose, solidifying it into continuous filaments that are washed, bleached, and spun into yarn. The end product is chemically similar to cotton — both are cellulose — but its different physical structure gives viscose its characteristic drape and sheen.
The process was developed in the late nineteenth century and commercialized in the early twentieth, when the fiber was marketed as "artificial silk." No animal inputs are involved at any stage: the feedstock is plant-derived, and the processing chemicals are mineral- or petroleum-based.
Viscose, Rayon, Modal, Lyocell: Reading the Label
"Viscose" and "rayon" describe the same fiber. In the United States, the Federal Trade Commission recognizes "rayon" as a generic fiber name, so American garment labels typically read "rayon." In Europe, the same fiber is labeled "viscose." Technically, rayon functions as an umbrella term for regenerated cellulose fibers, with viscose being the standard production method.
Several variants appear on labels. Modal is a higher-strength viscose variant usually made from beechwood, common in underwear and T-shirts. Lyocell, best known under the TENCEL brand, is made with a different, closed-loop solvent process. Cupro, sometimes sold as Bemberg, is regenerated from cotton linters and often used in jacket linings. All of these are plant-derived and vegan.
"Bamboo" fabric deserves particular attention. Most textiles marketed as bamboo are bamboo viscose, processed with the same chemistry as any other viscose. The FTC requires such products to be labeled "rayon made from bamboo" and has taken enforcement action against sellers marketing them as natural bamboo fiber.
Products Where Viscose Appears
Viscose is among the most widely used fibers in the world, and it appears well beyond obvious clothing applications. In apparel, it dominates flowing blouses, dresses, and jacket linings, and it is the standard fiber for imitation silk, which makes it directly relevant to vegans seeking silk alternatives. Many velvets, chenilles, and embroidery threads are also viscose rather than silk or cotton.
Outside the closet, rayon is a common fiber in tampons and other absorbent hygiene products, as well as in nonwoven wipes. The same viscose chemistry produces cellophane film and the clear cellulose casings used in sausage manufacturing. Rayon cord has also historically been used to reinforce tires and remains in use in some high-performance applications.
For label readers, this breadth matters mainly in one direction: viscose is a vegan material wherever it appears. The relevant question on a garment label is usually not whether viscose itself is animal-derived — it is not — but whether it is blended with wool or silk in the same fabric.
Environmental Profile and Cleaner Alternatives
Viscose is vegan, but it is not automatically a low-impact choice. Conventional production relies on carbon disulfide, a neurotoxic solvent with a long documented history of occupational disease among viscose workers. Facilities without modern chemical recovery can release carbon disulfide and other byproducts into air and water. Forest sourcing is a second concern: investigations and industry audits have traced some viscose supply chains to endangered and old-growth forests, which prompted the Canopy initiative to rank producers on their sourcing practices.
The cellulosic fiber family offers cleaner options. Lyocell (TENCEL) uses a nontoxic solvent in a closed loop that recovers nearly all of it, and branded lyocell typically comes with wood traceability. Modal from certified plantations with high chemical recovery sits in between. Recycled-cellulose fibers made from textile waste are an emerging category.
For a vegan wardrobe, the practical hierarchy is straightforward: lyocell over modal, modal over generic viscose, and certified or branded fiber over unbranded fiber, since branding usually indicates auditable production standards.
Frequently asked questions
Is viscose vegan?
Yes, viscose is vegan. It is made entirely from wood cellulose and processed with mineral- and petroleum-based chemicals, with no animal inputs at any stage. It is in fact one of the most common vegan substitutes for silk.
Is rayon the same as viscose?
For practical purposes, yes. Rayon is the American term and viscose the European term for the same regenerated cellulose fiber. Strictly speaking, rayon is an umbrella category that also includes modal and lyocell, but a garment labeled rayon in the US would typically be labeled viscose in the EU.
Is bamboo fabric actually viscose?
Usually, yes. Most fabric marketed as bamboo is bamboo viscose, made by dissolving bamboo cellulose with the same chemicals used for wood-based viscose. US regulators require such textiles to be labeled "rayon made from bamboo." It is vegan either way, but it does not retain the natural properties of the bamboo plant.
Is viscose environmentally friendly?
Conventional viscose has a high environmental impact despite being plant-based. Its production uses carbon disulfide, a toxic solvent linked to worker health problems, and some supply chains have been traced to endangered forests. Lyocell, made in a closed-loop process, is the significantly cleaner cellulosic alternative.
Is viscose a natural or synthetic fabric?
Viscose is semi-synthetic. Its raw material is natural wood cellulose, but the fiber itself is created through intensive chemical processing, so it fits neither the fully natural category, like cotton or linen, nor the fully synthetic one, like polyester. Textile standards classify it as a regenerated or man-made cellulosic fiber.
What can I use instead of viscose?
Lyocell, sold as TENCEL, is the closest substitute, offering a similar drape with a much cleaner production process. Modal is another regenerated option, while organic cotton, linen, and hemp are fully natural plant fibers. All of these are vegan; the choice mainly affects environmental footprint and fabric feel.
