From Yarn to Fabric: Understanding the Complete Viscose Manufacturing Process

A Practical Guide to Viscose Production from Raw Material to Finished Fabric


Understanding the viscose manufacturing process is essential for anyone in the textile industry—whether you’re a manufacturer, quality control professional, buyer, or entrepreneur. At Reaghan Fashions, we believe knowledge of production processes leads to better sourcing decisions and higher quality outcomes.

This guide breaks down the complete journey of viscose from wood pulp to finished fabric in clear, practical terms.


Overview: The Viscose Production Journey

The complete viscose manufacturing process consists of two main phases:

Phase 1: Fiber/Yarn Production (Wood pulp → Viscose fiber/yarn)
Phase 2: Fabric Manufacturing (Yarn → Finished fabric)

Total Timeline: 15-30 days depending on specifications and finishing requirements

Key Players:

  • Pulp producers
  • Chemical suppliers
  • Viscose fiber/yarn manufacturers
  • Fabric producers (weavers/knitters)
  • Finishing units

PHASE 1: Viscose Fiber & Yarn Production

Step 1: Raw Material Preparation (Days 1-2)

Wood Pulp Sourcing:

  • Primary sources: Beech, pine, eucalyptus, bamboo
  • Quality requirement: 92-96% cellulose content
  • Sustainable option: FSC/PEFC certified pulp

Process:

  1. Wood chips processed into pulp sheets
  2. Pulp sheets dried and pressed
  3. Quality testing for cellulose purity
  4. Storage in moisture-controlled environment

Quality Check: Moisture content (6-8%), alpha-cellulose percentage, impurities


Step 2: Steeping (Days 3-4)

Objective: Convert cellulose into alkali cellulose

Process:

  1. Pulp sheets steeped in 18-20% sodium hydroxide (caustic soda) solution
  2. Duration: 1-3 hours at controlled temperature (18-25°C)
  3. Excess liquid pressed out
  4. Result: White, crumbly alkali cellulose sheets

Chemical Ratio: 1 kg pulp : 2.5-3 liters caustic solution

Quality Parameters:

  • Uniform penetration of caustic
  • Proper moisture retention (specific weight ratio)
  • Temperature control (prevents degradation)

Common Issue: Uneven steeping causes yarn irregularities later


Step 3: Pressing & Shredding (Day 4)

Pressing:

  • Alkali cellulose pressed to remove excess caustic
  • Target: 2.5-3:1 weight ratio (alkali cellulose to original pulp)

Shredding:

  • Pressed sheets mechanically shredded into fine crumbs
  • Increased surface area for next step
  • Result: White fluffy material called “cellulose crumbs”

Quality Check: Uniform crumb size, no lumps, consistent moisture


Step 4: Aging/Ripening (Days 5-7)

Objective: Depolymerize cellulose to optimal chain length

Process:

  1. Cellulose crumbs stored in controlled conditions
  2. Temperature: 18-25°C
  3. Duration: 48-72 hours
  4. Oxygen exposure causes controlled degradation

Why It Matters:

  • Too short: Viscose solution too viscous (processing difficulty)
  • Too long: Fiber strength reduced
  • Optimal aging: Balance of processability and strength

Monitoring: Regular viscosity testing, degree of polymerization measurement

Quality Parameter: DP (Degree of Polymerization) reduced from ~600-1000 to ~250-350


Step 5: Xanthation (Day 7)

Objective: Create soluble cellulose derivative

Process:

  1. Aged alkali cellulose mixed with carbon disulfide (CS₂)
  2. CS₂ amount: 25-40% by weight of cellulose
  3. Temperature: 20-30°C
  4. Duration: 2-3 hours in sealed churns
  5. Color change: White → orange (cellulose xanthate formation)

Chemical Reaction:
Alkali Cellulose + CS₂ → Sodium Cellulose Xanthate

Safety Critical: CS₂ is toxic and flammable—requires strict safety protocols

Quality Check:

  • Uniform orange color
  • Proper CS₂ absorption
  • No unreacted white spots

Step 6: Dissolving (Days 8-9)

Objective: Create viscose spinning solution

Process:

  1. Orange crumbs dissolved in dilute caustic soda (4-6%)
  2. Mechanical stirring for 4-6 hours
  3. Temperature maintained at 10-18°C (cooling required)
  4. Result: Thick, honey-like orange viscose solution

Viscosity Target: 50-150 seconds (measured by viscometer)

Quality Parameters:

  • Complete dissolution (no undissolved particles)
  • Proper viscosity for spinning
  • Correct chemical composition

Step 7: Ripening of Viscose (Days 9-10)

Second aging phase (not to be confused with cellulose aging)

Objective: Achieve optimal viscosity and filterability

Process:

  1. Viscose stored at 10-18°C
  2. Duration: 24-48 hours
  3. Gradual viscosity increase
  4. Chemical reactions continue

Monitoring: Hourly viscosity checks, salt test index


Step 8: Filtration (Day 10)

Objective: Remove impurities and undissolved particles

Process:

  1. Multi-stage filtration through fine mesh
  2. Vacuum filtration common
  3. Removal of gel particles, fiber bundles, dirt

Critical for:

  • Preventing nozzle blockage during spinning
  • Ensuring uniform fiber quality
  • Reducing fabric defects

Quality Standard: 99.9% particle-free solution


Step 9: Deaeration (Day 10)

Objective: Remove air bubbles from viscose

Process:

  1. Viscose subjected to vacuum
  2. Air bubbles rise and removed
  3. Essential for uniform spinning

Why Important: Air bubbles cause fiber breaks and irregularities


Step 10: Spinning (Days 11-12)

The transformation: Liquid viscose → Solid fiber

Process:

For Filament Yarn:

  1. Viscose pumped through spinnerets (metal plates with tiny holes)
  2. Holes: 0.05-0.15mm diameter, 100-10,000 holes per spinneret
  3. Extruded into coagulation bath containing:
    • Sulfuric acid (10-12%)
    • Sodium sulfate (15-20%)
    • Zinc sulfate (1-2%)
    • Temperature: 40-50°C

Chemical Regeneration:

  • Acid neutralizes alkali
  • Cellulose xanthate reconverts to cellulose
  • CS₂ released (captured for reuse in sustainable plants)
  • Solid cellulose filaments formed
  1. Filaments washed to remove chemicals
  2. Multiple filaments combined into yarn
  3. Twist applied (varies by end use)
  4. Wound onto bobbins/cones

For Spun Yarn:

  • Filaments cut into staple fibers (38mm-150mm length)
  • Crimped for cohesion
  • Spun using ring spinning or rotor spinning systems
  • Similar to cotton spinning process

Spinning Speed: 40-150 meters/minute depending on denier

Quality Parameters:

  • Denier/count uniformity
  • Tenacity (strength)
  • Elongation
  • Luster (bright, semi-dull, dull based on titanium dioxide addition)

Step 11: Washing & Treatment (Days 12-13)

Multi-stage washing:

  1. Hot water wash (removes residual acid and salts)
  2. Neutralization (mild alkali treatment)
  3. Desulfurization (removes sulfur compounds)
  4. Final rinse

Treatment:

  • Oil/spin finish application (0.3-1% by weight)
  • Improves processing in weaving/knitting
  • Reduces static electricity
  • Protects fibers during handling

Quality Check: pH neutral, minimal chemical residue, proper lubrication


Step 12: Drying (Day 13)

Process:

  1. Centrifugal water removal
  2. Hot air drying (80-110°C)
  3. Moisture content reduced to 11-13%

Critical: Controlled drying prevents fiber damage


Step 13: Yarn Conditioning & Packaging (Day 14)

Final Steps:

  1. Yarn conditioned at standard atmospheric conditions (65% RH, 20°C)
  2. Quality testing (tensile strength, evenness, twist, count)
  3. Packaging:
    • Filament yarn: Cones, bobbins, cheeses
    • Spun yarn: Cones, hanks, cheese
  4. Labeling (count/denier, lot number, weight)
  5. Storage in controlled environment

Quality Documentation:

  • Test certificates
  • Batch traceability
  • Specifications conformance

Phase 1 Complete: Viscose yarn ready for fabric manufacturing


PHASE 2: Fabric Manufacturing from Viscose Yarn

Path A: Weaving Process

Step 1: Yarn Preparation (Days 15-16)

Winding:

  • Transfer yarn from production packages to weaver’s beams
  • Remove defects and weak spots
  • Create uniform tension

Warping (for warp yarn):

  • Multiple yarn ends assembled parallel
  • Arranged on warp beam
  • Length: 200-2000 meters depending on fabric order

Quality Check: Tension uniformity, end breaks minimized


Step 2: Sizing (Warp Yarn Only) (Day 17)

Why Needed: Viscose loses 30-50% strength when wet; sizing adds temporary strength

Process:

  1. Warp yarn passed through sizing solution
  2. Sizing agents: Modified starch, PVA, CMC, acrylic polymers
  3. Concentration: 6-12% depending on yarn count
  4. Drying on hot cylinders
  5. Result: Protected, strengthened warp yarn

Size Recipe for Viscose:

  • Modified starch: 60-70%
  • Wax/softener: 10-15%
  • Lubricant: 5-10%
  • Moisture retention agent: 5-10%

Quality Parameters:

  • Size add-on: 8-12% by weight
  • Uniform coverage
  • Flexibility retained
  • No brittleness

Common Issue: Incorrect sizing causes excessive warp breaks during weaving

  • Air-jet loom: Very high speed, 600-1200 picks/minute (requires strong yarn)

Weaving Parameters for Viscose:

  • Tension: Lower than cotton (viscose is weaker when wet from sizing moisture)
  • Speed: 10-15% slower than cotton due to lower strength
  • Humidity: 65-70% RH (prevents brittleness)
  • Temperature: 25-28°C

Quality Monitoring:

  • Warp break rate (target: <5 breaks/100,000 picks)
  • Fabric width uniformity
  • Weave pattern accuracy
  • Surface defects (slubs, holes, floats)

Production Rate: 40-80 meters/day per loom (varies by fabric density and design)


Step 5: Grey Fabric Inspection (Day 22)

Four-point system grading:

Inspection: Fabric run on inspection machine at slow speed under proper lighting


Common to Both: Fabric Finishing (Days 23-28)

The finishing stage transforms grey fabric into market-ready material.

Step 1: Singeing (Day 23)

Objective: Remove surface fibers (fuzz) for smooth finish

Process:

  • Fabric passed over gas flames or hot plates at high speed
  • Surface fibers burn off
  • Critical for formal fabrics, not always done for casual wear

Viscose Consideration: Lower flame intensity (viscose burns easily)


Step 2: Desizing (Woven Only) (Day 23)

Objective: Remove sizing agents from warp

Process:

  1. Enzymatic treatment (amylase enzymes for starch)
  2. Hot water wash (60-80°C)
  3. Mechanical action

Quality Check: Complete size removal (starch test negative)


Step 3: Scouring (Day 24)

Objective: Remove oils, waxes, dirt, and impurities

  2. Alternative: Sodium chlorite (less common, requires acidic pH)

Viscose Caution: Over-bleaching damages cellulose; controlled time/temperature critical

Result: Bright white fabric, improved dye uptake


Step 5: Mercerizing (Optional, Premium Fabrics) (Day 25)

Objective: Enhance luster, strength, and dye affinity

Process:

  1. Fabric treated with concentrated caustic soda (20-28%)
  2. Under tension to prevent shrinkage
  3. Temperature: 15-25°C
  4. Duration: 45-90 seconds
  5. Thorough washing to remove caustic

Benefits:
✅ Increased luster (silk-like sheen)
