Lyocell

• Manufacturer Lenzing
• Brand Name Tencel
• Raw material Wood Pulp

12
Lyocell Manufacturing Process

• Wood pulp from trees dissolved in amine oxide to
  form a viscous solution
• Filtered
• Extruded to fine filaments
• Washed to remove solvent
• Amine oxide is recovered and recycled

13
Lyocell

• Fibrillation
• wet fibers through abrasive action develop micro
  fibrils on its surface
• Manipulating fibrillation gives a variety of
  finishes such as peach-skin surface
• Fibrillation done by enzyme (cellulase)
  treatments
