Tencel vs. Modal vs. Lyocell: Which Fiber Should You Choose?

Short answer: Tencel, modal and lyocell are all cellulose fibers made from wood pulp, so they feel similar — soft, drapey and breathable. The difference is in how they are made: lyocell uses a closed-loop solvent process (more sustainable), modal is a softer, older viscose variant, and Tencel is a brand name (from Lenzing) that covers both lyocell and modal. Choose lyocell for sustainability and drape, modal for softness and cost, and check whether the "Tencel" you are offered is lyocell or modal.

The naming confuses almost every buyer the first time. This guide untangles it.

What These Fibers Actually Are

All three start from wood pulp (usually eucalyptus or beech), dissolved and regenerated into fiber. They are semi-synthetic cellulosics — natural raw material, manufactured process.

Tencel is Lenzing's brand for its lyocell and modal fibers. So "Tencel lyocell" and "Tencel modal" are both accurate; "Tencel" alone is ambiguous.

Head-to-Head Comparison

Lyocell: The Sustainability and Performance Choice

Lyocell is the fiber to specify when sustainability is a priority:

Common uses: T-shirts, dresses, loungewear, lightweight knit tops, and premium basics.

Modal: The Softness and Value Choice

Modal is the fiber for softness at a friendlier cost:

Common uses: underwear, T-shirts, loungewear, and next-to-skin knits.

Where They Fit in Knitwear

All three knit well and are common in:

They are less suited to heavy or hard-wearing garments, where cotton or synthetics outperform them.

Sustainability: What to Verify

"Sustainable" needs a name behind it:

A "Tencel" claim without knowing whether it is lyocell or modal is an incomplete claim.

Common Mistakes

Conclusion

Tencel, modal and lyocell are all wood-pulp cellulosics with a soft, drapey hand. Choose lyocell for sustainability and wet strength, modal for softness and value, and always confirm which one a "Tencel" offer actually is. Specify the fiber precisely, test for shrinkage and pilling, and back any sustainability claim with a named process. The names stop being confusing once you know that Tencel is a brand and lyocell is a process.

Key Takeaways for Buyers

What we would do in your position

Start with one fabric across two or three styles. It halves your development cost, gets you over mill minimums and stops you overcommitting to a single style before you know what actually sells. Widen the range once the first drop has told you something.
