Viscose Fabric
A semi-synthetic regenerated cellulose fabric within the $17.85 billion global viscose fiber market (4.8% CAGR), viscose/rayon was patented by Cross & Bevan in 1891 and commercialized by Courtaulds in 1905 — offering 11–14% moisture regain (vs. cotton's 8%), exceptional dye affinity, and silk-like drape at $5–30/yard across five generations: regular viscose, Modal, lyocell, Cupro, and bamboo viscose.

What is Viscose Fabric?
Viscose (rayon in the US market, named by the FTC in 1924) is a semi-synthetic regenerated cellulose fiber made by chemically dissolving wood pulp and extruding it into fibers through the xanthation process. The $17.85 billion global viscose fiber market (2025) produces 6.3 million tonnes annually, with Asia-Pacific accounting for 79.83% of production.
Historical timeline:
- 1884: French chemist Hilaire de Chardonnet patents first artificial silk (cellulose nitrate — highly flammable, limited viability)
- 1891–1892: English chemists Charles Cross, Edward Bevan, and Clayton Beadle patent the viscose process using sodium cellulose xanthate — foundation of modern production
- 1905: British company Courtaulds begins first commercial viscose production in Coventry, UK (acquired Cross & Bevan patents in 1904)
- 1924: US FTC officially adopts the name "rayon" to replace "artificial silk"
- 1950s: Modal (high-wet-modulus viscose) developed in Japan
- 1990s: Lyocell/TENCEL™ closed-loop process commercialized by Lenzing AG
Xanthation production process:
- Wood pulp steeped in 18% sodium hydroxide solution
- Excess alkali pressed out → alkali cellulose crumbs
- Controlled aging for optimal polymerization
- Crumbs react with carbon disulfide (32–34% CS₂) at 20–30°C → sodium cellulose xanthate (orange-yellow)
- Xanthate dissolved in dilute caustic soda → viscous solution ("viscose" = viscous)
- Filtered, ripened to optimal viscosity
- Extruded through spinnerets into sulfuric acid bath → regenerates to solid cellulose fibers
- Washed, desulfurized, bleached, finished
Viscose family of fibers (five generations):
- Regular viscose/rayon: 90%+ of production — affordable, drapey, biodegradable, wrinkles easily, loses 50–60% strength when wet
- Modal (HWM): Second-generation from beech pulp — retains 85–90% wet strength, softer, resists shrinkage; Lenzing Austria produces 119,000 tonnes/year
- Lyocell/TENCEL™: Third-generation — closed-loop NMMO process with 99%+ chemical recovery, maintains wet strength, strongest fiber
- Cupro (cuprammonium rayon): Made from cotton linter waste — silk-like hand, "vegan silk" positioning
- Bamboo viscose: Chemically identical to wood viscose but bamboo-sourced feedstock — FTC labeling restrictions apply
Technical specifications:
- Moisture regain: 11–14% at standard conditions (cotton: 8%, polyester: 0.4%) — highly absorbent, up to 12% of weight
- Drape: Smooth filament structure with low bending rigidity and friction coefficient of 0.2 (lower than most fibers) → fluid silk-like drape
- Dye affinity: Exceptional for reactive, direct, and vat dyes — produces deep, saturated colors
- GSM range: Plain weaves 130–180 GSM, midweight prints 170–340 GSM, viscose twill typically heavier
- Biodegradability: Yes — cellulose-based, decomposes naturally
- Weakness: Limited elasticity, poor wrinkle recovery, sensitive to water damage
Why This Matters for Fashion Entrepreneurs
Viscose is the most commercially important fabric for India's mid-range fashion sector, serving a $17.85 billion global market — its silk-like drape at cotton-level pricing makes it the backbone of ethnic wear, summer fashion, and fast fashion collections.
Market opportunity by channel:
- Indian ethnic wear: Viscose kurtas, sarees, and dupattas dominate the ₹500–2,000 price range — India's ethnic wear market exceeds ₹1.4 lakh crore, and viscose is the go-to fabric after cotton
- Fast fashion (H&M, Zara): ~10% of both brands' fabric supply is viscose — H&M dresses at $48–52, Zara dresses at $48. Viscose's dye affinity enables the rapid color changes fast fashion demands
- Sustainable premium (Reformation): 50%+ of garments use viscose/TENCEL/recycled fibers at $200+ per dress — demonstrating viscose family's versatility from fast fashion to premium
- Summer fashion: 11–14% moisture regain makes viscose ideal for India's 8-month summer — breathable, cool to touch, with drape that flatters loose-fit silhouettes
Building a viscose-based brand — key decisions:
- Sustainability positioning: Canopy's Hot Button Report rates producers — Lenzing, Aditya Birla, and Tangshan Sanyou hold "Dark Green Shirt" (highest tier), representing 53% of global supply. Source from these producers for credible eco-narratives
- Wrinkle problem solutions: Blend with polyester (adds wrinkle resistance), use viscose crepe (texture hides wrinkles), or apply wrinkle-resistant finishing — the #1 consumer complaint about viscose
- Print-first strategy: Viscose's exceptional dye affinity produces the most vibrant prints in any fabric category — essential for digital print and seasonal collections
- Wet-strength awareness: Regular viscose loses 50–60% strength when wet — design care labels accordingly and educate customers to avoid machine washing without mesh bags

Pricing & Costs
Viscose fabric pricing by quality tier:
- Basic viscose (printed): $5–10/yard / ₹80–200/meter — commodity-grade for fast fashion and ethnic basics
- Mid-range viscose (yarn-dyed): $8–16/yard / ₹150–350/meter — branded casualwear and summer collections
- Premium Modal/HWM: $12–22/yard / ₹300–600/meter — enhanced wet strength and softness for premium innerwear

- Specialty blends: $18–40/yard / ₹600–1,500/meter — viscose-silk, viscose-linen, and designer blends
- Bamboo viscose: $10–25/yard / ₹200–500/meter — eco-marketing premium (FTC labeling rules apply)
VSF commodity pricing (per tonne):
- 2024 range: $590–740/tonne (declined due to weak apparel demand)
- Q4 2024 China: $1,713/MT FOB Shanghai
- India VFY March 2025: ₹413,300/MT (~$4,960/MT)
Cost calculation factors:
- Fabric wastage: Budget 12–15% for cutting loss (viscose's drape makes cutting slightly more challenging than cotton)
- Shrinkage buffer: Add 5–8% for non-pre-shrunk viscose — always specify pre-shrunk in tech packs
- Print cost: Digital printing adds $1–3/yard; screen printing $0.50–1.50/yard — viscose's dye affinity makes it cost-effective for prints
- Wet processing: Garment washing adds risk due to viscose's 50–60% wet strength loss — factor in higher reject rates (3–5% vs. 1–2% for cotton)
ROI insight:
Printed viscose kurtas can be produced at ₹150–350 per piece and retailed at ₹800–2,000 — delivering 3–5x markup. Viscose offers the best drape-to-cost ratio in fashion: a $5/yard viscose dress achieves nearly identical drape to a $25/yard silk charmeuse at 1/5th the fabric cost, making it the foundation of affordable luxury in ethnic wear and summer collections.
Frequently Asked Questions
Viscose (rayon) is a semi-synthetic regenerated cellulose fiber made by chemically dissolving wood pulp through the xanthation process — pulp is steeped in 18% sodium hydroxide, reacted with carbon disulfide to form sodium cellulose xanthate, dissolved in caustic soda, then extruded through spinnerets into a sulfuric acid bath where it regenerates to solid fibers. Patented in 1891–1892 by Cross & Bevan, commercialized by Courtaulds in 1905, and named "rayon" by the FTC in 1924, viscose now represents a $17.85 billion global market producing 6.3 million tonnes annually with Asia-Pacific accounting for 79.83% of production.
Viscose and rayon are identical — "rayon" is the US term (FTC 1924), "viscose" is used in Europe and Asia. Modal is second-generation high-wet-modulus (HWM) viscose from beech pulp, retaining 85–90% wet strength versus regular viscose's 50–60% — softer, more durable, resists shrinkage, costs 30–60% more (Lenzing Austria produces 119,000 tonnes/year). Lyocell/TENCEL™ is third-generation using closed-loop NMMO process with 99%+ chemical recovery — strongest fiber, best sustainability credentials, highest cost ($15–30/yard vs. viscose's $5–10/yard).
Viscose is semi-synthetic (regenerated cellulose) — it starts with natural cellulose from wood pulp but requires intensive chemical processing involving sodium hydroxide, carbon disulfide, and sulfuric acid to dissolve and regenerate into fibers. Unlike fully synthetic polyester (petroleum-derived), viscose is plant-based and biodegradable. Unlike natural cotton and linen (mechanically processed), viscose requires chemical transformation. This dual nature makes sustainability positioning nuanced — Canopy's 2024 report rates top producers (Lenzing, Aditya Birla, Tangshan Sanyou) with "Dark Green Shirt" for responsible sourcing practices.
