Lyocell T Shirts: What Decorators Should Know
What lyocell is made of, how lyocell t shirts compare with modal, viscose and cotton, and how to print, press and label them.
Lyocell tees for decorators: fiber basics, print and press tests, care and fiber content labeling. No eco or health claims.
What is lyocell fabric? Lyocell is a regenerated cellulose fiber, closely related to rayon, made by dissolving wood based cellulose in a solvent and spinning it into fiber, so it is not a plastic; lyocell t shirts feel smooth and drape well and generally print more like cotton than polyester, but ink adhesion, heat and shrink still need a test on the blank.
Key rule: lyocell is a cellulose fiber, so start from cotton style decorating, then confirm every setting on the actual blank and blend.

Lyocell vs Modal vs Viscose vs Cotton
| Fiber | Fiber type | Hand and drape | Print notes |
|---|---|---|---|
| Lyocell | Regenerated cellulose; solvent spun; related to rayon | Smooth, soft, drapey; good wet strength | Cellulose fiber, so dyes and prints much like cotton; test pretreat, cure and press |
| Modal | Regenerated cellulose made by its own process | Very soft, silky drape | Cellulose based; test on the blank |
| Viscose rayon | Regenerated cellulose made by the older viscose process | Soft, drapey; weaker when wet | Cellulose based; heat and moisture sensitivity calls for gentle tests |
| Cotton | Natural cellulose fiber | Wide range from crisp to soft | Widest ink and press window; the reference point for most decorators |
All four fibers are cellulose. The differences decorators feel come from how the fiber was made and how the yarn and knit were built. Polyester behaves differently; see the polyester vs cotton guide.
What Is Lyocell Fabric Made Of
Lyocell starts as cellulose, typically from wood pulp. The pulp is dissolved directly in an organic solvent, and the solution is pushed through a spinneret into a bath where the cellulose comes back out as fiber. The solvent is then recovered and the fiber is washed and dried.
US fiber labeling rules have their own definitions for regenerated cellulose fibers; check the current FTC rules for the exact wording. In plain terms: lyocell is plant based cellulose that has been dissolved and re formed, not a synthetic polymer like polyester or nylon.
Many blanks blend lyocell with cotton, polyester or spandex. The blend, not the lyocell share alone, decides how the shirt prints and presses.
Printing and Pressing Lyocell
Screen printing
Because lyocell is cellulose, inks that work on cotton are the usual starting point. Water based and soft hand inks suit the smooth drape. If the blank includes polyester, follow the ink maker's guidance for poly blends and check for dye migration on dyed colors.
DTG and DTF
Direct to garment printing on lyocell and lyocell blends needs pretreatment and cure tests on the exact blank, following the printer and ink maker. Too much pretreat can stiffen the hand on a smooth fabric. Direct to film and other heat applied transfers should start at the transfer maker's settings with a cover sheet, then be checked for scorching, shine and press marks.
Embroidery
Lightweight lyocell jersey drapes and stretches, so use a knit friendly stabilizer and a test sew. Smooth, fine fabrics show puckering and hoop marks more readily.
On any lyocell blank, press marks and shine can appear on a smooth surface. A test garment is the cheapest insurance.
When Lyocell Blanks Fit an Order
Lyocell and lyocell blend tees suit retail, fashion and premium merch where a smooth hand and soft drape matter. Before quoting, confirm the exact blend, weight and color depth on the supplier spec sheet, and ask for samples to print and press. Blends with polyester or spandex change ink, heat and stretch behavior, so test the blend you will actually receive. The wholesale blanks guide has the full blank checklist, and the jersey fabric guide explains how the knit itself behaves. Build a sample approval step into the quote so the customer sees the hand and print on the real garment before the run.
Care and Shrink
Fiber references describe lyocell as washable, with good wet strength, and as more resistant to shrinking and wrinkling than standard viscose rayon. Laundering studies still measure some shrinkage, and results depend on knit, finish and blend. There is no single shrink figure to promise a customer.
Follow the care label on the specific garment, and wash test a decorated sample if fit is critical. If the care label calls for cool washing or low dryer heat, pass that on to the customer with the order.
Labeling Fiber Content
In the US, textile fiber products need fiber content labels that use generic fiber names. Use the generic fiber name, such as "lyocell", on labels and product copy rather than a fiber trademark, and keep percentages matched to the supplier spec sheet.
Do not add environmental, sustainability, biodegradability or health claims to lyocell products on the strength of the fiber name alone. Such claims need their own substantiation. This is general information, not legal advice; ask counsel for formal label or claim review.
Frequently Asked Questions About Lyocell (FAQ)
What is lyocell fabric made of?
Regenerated cellulose, typically from wood pulp, that is dissolved in a solvent and spun back into fiber.
Is lyocell a plastic?
No. It is a cellulose fiber, closely related to rayon, not a synthetic polymer like polyester.
Can you screen print on lyocell?
Yes. Start with inks and cure settings you would use on cotton, adjust for any polyester in the blend, and test on the blank.
Lyocell vs modal: what is the difference?
Both are regenerated cellulose fibers, made by different processes; lyocell uses a direct solvent spinning process. Hand and drape differ by blank, so compare samples.
Can I call lyocell eco friendly?
Not on the fiber name alone. Environmental claims need specific substantiation. Stick to the fiber content and supplier documentation. This is not legal advice. For questions about chemical safety, rely on the supplier's documentation.
Supplier note: figures and settings here are hedged starting points that vary by blank, film, stone, leather, ink and certificate; confirm every claim against the supplier or manufacturer spec sheet, the garment care label and current certificates. No fiber trademarks and no eco or health claims are made on this page; this is not legal advice.
