What Is Viscose Fabric? The Silk Alternative Explained
What is viscose fabric? Discover how viscous wood cellulose is transformed into fluid, breathable, silk-like cloth with washing rules and styling advice.
What Is Viscose Fabric in Simple Terms?
What is viscose fabric? Viscose fabric is a lightweight, semi-synthetic textile woven from regenerated wood cellulose that gets its name from the honey-like viscous solution used in production. Famous for its silky luster, skin-cooling breathability, and flowing drape, viscose is one of fashion’s most popular fabrics for blouses, sundresses, and luxury linings.
Often called "artificial silk," viscose gives you the graceful movement of luxury silk at a much friendlier price point. Because it is made of plant cellulose, it breathes just like cotton and feels remarkably cool against warm skin.
How Viscose Is Made: The Honey Solution
The name "viscose" comes from the word viscous (thick and syrupy):
- Dissolving Wood: Wood chips from trees like eucalyptus and pine are treated with sodium hydroxide to extract raw white cellulose sheets.
- Creating Xanthate: The sheets are shredded and reacted with carbon disulfide, turning into an amber crumb.
- The Viscose Honey: The crumb dissolves in a caustic soda bath, forming a thick, golden fluid that looks just like raw honey.
- Extrusion through Spinnerets: The thick fluid is forced through microscopic spinneret nozzles into an acid bath, which instantly solidifies the liquid back into solid cellulose filaments ready for spinning.
Viscose vs. Silk: The Affordable Elegance
Before viscose was commercialized in 1892, flowing shiny fabrics were exclusively available to royalty through expensive silkworm cultivation. Viscose democratized fluid elegance:
While silk is an animal protein fiber spun by silkworms, viscose is plant-based cellulose. Silk has a triangular fiber cross-section that produces a subtle prism shimmer, whereas viscose has microscopic longitudinal grooves that reflect a bright, clean sheen. Viscose is vegan-friendly and significantly more affordable than mulberry silk.
Key Benefits of Viscose Fabric in Clothing
- Exceptional Fluid Movement: Viscose cascades over the body with a liquid-like drape that flatteringly moves as you walk.
- Cool and Moisture Wicking: Absorbs sweat fast and allows ambient heat to escape, making it ideal for tropical weather.
- Hypoallergenic and Breathable: Gentle against delicate skin, producing zero static shock or scratchiness.
- Rich Color Fastness: Cellulose fibers hold dyes deeply, enabling dazzling prints and rich jewel tones that do not wash out easily.
Viscose Technical Properties Table
| Technical Property | Value / Rating | Practical Garment Impact |
|---|---|---|
| Moisture Regain | 11% – 13% | Absorbs more moisture than cotton (8.5%), keeping skin dry |
| Wet Tensile Strength | 50% of Dry Strength | Fibers become fragile when submerged; wash gently |
| Elastic Recovery | Moderate (30%–50%) | Can crease; often blended with elastane for stretchy knits |
| Ignition Behavior | Burns like paper | Smells like burnt wood/paper with soft gray ash (pure cellulose) |
How to Wash Viscose Clothes Without Ruining Them
Because viscose loses half of its strength when wet, washing requires mindful care:
- Cold water only (30°C / 85°F): Warm or hot water causes the cellulose fibers to swell, contract, and permanently shrink.
- Wash in a mesh laundry bag: Protects delicate viscose seams from catching on zippers or buttons in the drum.
- Never wring out: Roll in a towel to absorb water, then hang on a padded hanger or dry flat in the shade.
- Iron on reverse with steam: Iron on medium-low while damp with a pressing cloth to restore the fabric’s silky sheen.
Conclusion: Why Viscose Remains a Fashion Favorite
Now that you know what is viscose fabric, you can appreciate why global designers choose it for breezy warm-weather collections. Its combination of natural plant breathability and liquid-like drape makes viscose one of the most delightful, comfortable fabrics you will ever wear.
Frequently Asked Questions
Does viscose stretch over time?
Viscose does not have high natural elasticity. When wet, heavy viscose garments can stretch out if hung on wire hangers. Always store knit viscose sweaters folded flat.
Is viscose good for sensitive skin?
Yes, viscose is made of smooth plant cellulose with no sharp fiber ends, making it exceptionally soft, breathable, and gentle on easily irritated skin.
Can you steam viscose fabric?
Yes, garment steaming works wonderfully on viscose! Steaming relaxes wrinkles and restores the fabric’s natural fluid drape without the risk of scorching.
Is viscose environmentally friendly?
Viscose is biodegradable because it comes from wood trees. However, traditional manufacturing requires chemical management. Opting for certified sustainable viscose (like EcoVero) ensures responsible forestry and low-emission production.
