Rayon vs. Viscose: Terminology, Production, and Everyday Differences
Many shoppers are confused when they see "rayon" on one clothing label and "viscose" on another. In short: **all viscose is rayon, but not all rayon is viscose*
Many shoppers are confused when they see "rayon" on one clothing label and "viscose" on another. In short: **all viscose is rayon, but not all rayon is viscose**. "Rayon" is the overarching umbrella term used primarily in North America for man-made fibers regenerated from plant cellulose. "Viscose" is the European and global industry term specifically designating the classic xanthate chemical solution process. Other members of the rayon family include Modal and Lyocell.
When shopping, recognize that **Rayon** and **Viscose** on a clothing label refer to essentially the same silky, breathable plant-derived fabric. Choose both for draping dresses, printed blouses, and soft loungewear, but choose advanced rayons like **Lyocell or Modal** if you want higher wet strength and enhanced eco-credentials.
Detailed Head-to-Head Comparison
Regional Labeling Standards
Rayon (Umbrella Category): Standard legal term required on garment tags by the US Federal Trade Commission (FTC).
Viscose (Specific Subtype): Standard terminology across the UK, Europe, Australia, and South Asia.
If you buy the same blouse in New York and London, the US tag will likely read "100% Rayon" while the European tag reads "100% Viscose".
Chemical Process Variants
Rayon (Umbrella Category): Includes Viscose, Modal (beechwood), Lyocell (amine oxide), and Cupro (cotton linter).
Viscose (Specific Subtype): Specifically uses sodium hydroxide and carbon disulfide to dissolve wood pulp.
While standard viscose is the most widespread rayon, modern rayons like Lyocell (TENCEL™) use cleaner solvent methods.
Feel, Breathability & Drape
Rayon (Umbrella Category): Dependent on subtype; ranges from silky fluid (viscose) to resilient and soft (modal).
Viscose (Specific Subtype): Extremely silky, lightweight, cool against skin, with a heavy liquid drape.
Standard viscose and regular rayon feel virtually identical because 90%+ of general rayon is manufactured via the viscose route.
Laundering Care
Rayon (Umbrella Category): Modal and lyocell withstand machine washing better than classic viscose.
Viscose (Specific Subtype): Shrinks easily in hot water and weakens significantly when wet; prefers cold hand wash.
Always treat 100% viscose garments with care: wash in cold water on gentle cycle and reshape before laying flat to dry.
Frequently Asked Questions
Why did European countries adopt the name Viscose while the US uses Rayon?
In 1924, US retail associations coined "rayon" (from ray of light) to replace the misleading term "artificial silk." European manufacturers retained "viscose," named directly after the viscous liquid state during production.
