Difference in Viscose, Modal and Lyocell Fiber
Viscose, Modal, and Lyocell, all derived from wood pulp, differ in production methods, properties, and environmental impact despite being cellulosic fibers.
- Viscose (Viscose Rayon):
- Production: Viscose is the oldest and most widely produced cellulosic fiber. The process involves treating wood pulp with chemicals to produce a viscous solution, which is then extruded into fibers to create it.
- Properties: Soft, breathable, and comfortable to wear. It mimics natural fibers like cotton and silk but tends to wrinkle easily and can lose strength when wet.
- Environmental Impact: The production process involves chemicals and solvents, raising concerns about environmental pollution.
- Modal:
- Production: Modal is a type of rayon, similar to viscose, but produced using a slightly different manufacturing process. It undergoes an additional step that enhances its strength and durability.
- Properties: Known for its softness, smoothness, and excellent moisture absorption. It’s more resistant to shrinkage and fading compared to viscose.
- Environmental Impact: Due to its higher strength and reduced environmental impact during production, people often consider Modal more environmentally friendly than viscose.
- Lyocell (Tencel):
- Production: Manufacturers produce Lyocell using a solvent spinning technique in a closed-loop process, recycling the solvent. This method reduces environmental impact significantly.
- Properties: Known for its strength, breathability, and softness. It’s highly absorbent, more durable than viscose and modal, and less prone to wrinkles.
- Environmental Impact: Regarded as more environmentally sustainable due to its closed-loop production process, using non-toxic solvents and reducing water consumption.
In summary, while all three fibers are derived from wood pulp, their production methods, properties, and environmental impact vary. Lyocell (Tencel) stands out as the most environmentally friendly due to its closed-loop manufacturing process, while Modal offers enhanced durability compared to traditional viscose.

FAQs
What are Viscose, Modal, and Lyocell fibers?
- Viscose: Viscose, also known as rayon, is a semi-synthetic fiber made from wood pulp or cellulose. It’s known for its softness and similarity to natural fibers like cotton.
- Modal: Modal is a type of rayon made specifically from beech tree pulp. It’s known for its softness, breathability, and ability to retain color well.
- Lyocell: Lyocell is a newer generation of rayon made from wood pulp, typically sourced from eucalyptus or bamboo trees. It’s praised for its environmentally friendly production process and its soft, smooth texture.
How are they produced?
- Viscose: Viscose is produced through a chemical process involving the conversion of wood pulp into fibers using solvents and chemicals.
- Modal: Modal is also made using a similar chemical process to produce rayon, specifically from beech tree pulp, which results in a soft and silky fabric.
- Lyocell: Lyocell is produced through a closed-loop process using a solvent that is recycled, making it more environmentally friendly compared to the production of viscose and modal.
What are their characteristics?
- Viscose: It’s soft, breathable, and has good drape, but it may wrinkle easily and lose strength when wet.
- Modal: Modal is incredibly soft, more durable than viscose, and has better color retention, making it suitable for clothing that requires frequent washing.
- Lyocell: Lyocell is extremely soft, breathable, absorbent, and has good strength while being gentle on the skin. It’s also more environmentally friendly due to its production process.
What are their uses?
- Viscose: Viscose is used in a wide range of clothing items like shirts, dresses, and linings due to its softness and breathability.
- Modal: Modal is often used in activewear, underwear, pajamas, and other clothing that requires softness and good color retention.
- Lyocell: Lyocell is used in various clothing items including bedding, towels, denim, and activewear due to its softness, strength, and eco-friendly production.
Are they environmentally friendly?
- Viscose: The production of viscose involves chemicals that can have negative environmental impacts if not managed properly.
- Modal: Modal is considered relatively eco-friendly compared to viscose due to better water and energy efficiency in its production.
- Lyocell: Lyocell is considered one of the most environmentally friendly options among these fibers due to its closed-loop production process and the use of sustainable wood sources.
Understanding these distinctions can help you make more informed choices when it comes to selecting fabrics for various purposes.
