Rayon vs Viscose

Rayon and viscose are the most commonly confused fabric terms in the fashion industry. The truth is: viscose IS a type of rayon. Rayon is the broad family name for semi-synthetic cellulose fibers, and viscose is the most common member of that family.

Think of it like this: Rayon is to viscose what "car" is to "sedan." All viscose is rayon, but not all rayon is viscose. The rayon family includes viscose, modal, and lyocell (Tencel) — all made from wood pulp using slightly different chemical processes.

Rayon was first commercially produced in the 1890s as an affordable alternative to silk. It's made by dissolving cellulose (usually from wood pulp or bamboo) in chemicals and extruding it into fibers. The term "rayon" is used broadly across the family.

Viscose is the most common rayon variant, developed in 1891 by the viscose process. It uses carbon disulfide to dissolve cellulose, creating a silky, breathable, and affordable fabric. India is home to Grasim Industries (Aditya Birla Group), the world's largest viscose producer, making this fiber deeply relevant to Indian fashion manufacturing.

Rayon: The Semi-Synthetic Fiber Family

Rayon encompasses all regenerated cellulose fibers:

The Rayon Family:

• Viscose Rayon — Most common (70% of all rayon), silky drape, affordable
• Modal — From beech wood pulp, 50% more absorbent than cotton, ultra-soft
• Lyocell (Tencel) — From eucalyptus, closed-loop eco-friendly process, strong
• Cupro — From cotton linter waste, silk-like, used in luxury fashion
• Bamboo Rayon — From bamboo pulp, similar to viscose process

Key Properties (General):

• Drape: Excellent — falls beautifully, similar to silk
• Breathability: Good to excellent depending on the variant
• Softness: Generally soft and comfortable against skin
• Absorbency: Highly absorbent (more than cotton for modal/lyocell)
• Weakness: Generally poor wet strength — becomes weaker when wet

Market Position:

• Rayon accounts for ~6% of global fiber production
• Growing at 5-7% CAGR, driven by sustainability-positioned variants
• India is both a major producer and consumer of rayon fibers

Pricing (India Market — varies by variant):

• Viscose rayon: ₹60-400/meter
• Modal fabric: ₹150-500/meter
• Lyocell/Tencel: ₹200-700/meter

Viscose: The Silk of the People

Viscose specifically refers to rayon made by the viscose process:

Key Properties:

• Drape: Exceptional — the closest affordable alternative to silk drape
• Texture: Smooth, silky hand feel with slight luster
• Breathability: Good — more breathable than polyester, comparable to cotton
• Absorbency: High — absorbs moisture well, comfortable in heat
• Wet Strength: Poor — loses up to 50% of strength when wet
• Shrinkage: Prone to shrinking (5-8%) if not pre-treated or washed incorrectly

Types of Viscose:

• Regular Viscose — Standard quality, most affordable, widely available
• High-Tenacity Viscose — Stronger variant for industrial and outerwear uses
• Spun-Dyed Viscose — Color added during fiber production for better fastness
• Viscose Twill — Twill weave for slightly heavier, structured garments
• Viscose Crepe — Crinkled texture, popular for kurtas and ethnic wear

Best Use Cases:

• Kurtas and ethnic daily wear (biggest use in India)
• Summer dresses and tops
• Scarves and stoles
• Blouses and drape-heavy garments
• Lining fabric for structured garments

Pricing (India Market):

• Plain viscose: ₹60-150/meter
• Printed viscose: ₹100-300/meter
• Premium viscose (high-twist): ₹200-400/meter
• Viscose blends: ₹80-250/meter
