How to Read a Clothing Material Label: A Practical Guide to Blends

A clothing material label is best read as an ingredient list with proportions. It can tell you which fibers are present and how much of each is in the textile. It cannot, by itself, tell you the garment’s full sourcing story, environmental impact, durability, feel, or performance.

That distinction matters when a label includes terms such as lyocell or modal. Those words are useful facts. They are not a shortcut to a blanket “good” or “bad” verdict.

What do lyocell and modal mean?

In U.S. textile labeling, lyocell and modal are recognized generic names for manufactured fibers made from regenerated cellulose. In plain language, cellulose is processed into a fiber that can be spun and made into textile material. The exact production method, manufacturer, sourcing, and finished blend still matter.

TENCEL™ is different from a generic fiber name. It is Lenzing’s brand for specific lyocell and modal fibers. Not every product labeled “lyocell” or “modal” is made with TENCEL™ branded fiber. Unless product documentation establishes the branded input, the accurate word is the generic one on the composition record.

For reference, see the FTC textile-labeling guide and Lenzing’s TENCEL™ fiber information.

Start with the largest percentage

The largest number tells you which listed fiber makes up most of the blend. The remaining fibers are still part of the garment, so do not ignore them. A piece that is 93% lyocell is a different blend from one that is 35% lyocell, even though both can truthfully say that lyocell is present.

Here are current examples from HAE’s New In collection. The percentages below come from the live product composition records checked on July 13, 2026.

When lyocell is the clear majority

The Square-Neck Floral Bow Cami is listed as 93% lyocell and 7% flax. The useful reading is simple: lyocell is the dominant listed fiber, with flax making up the smaller share.

The Polka Dot Tiered A-Line Skirt is listed as 76% lyocell and 24% nylon. Lyocell is still the majority, but nearly one quarter of the blend is nylon. Both facts belong in the answer.

The Off-Shoulder Polka Dot Blouse and Polka Dot Swing Cami are each listed as 72% lyocell and 28% nylon. Matching percentages do not mean the garments will fit, drape, wear, or feel the same; construction and textile structure are separate questions.

When lyocell or modal is the smaller share

The Floral Lace V-Neck Peplum Top is listed as 35% lyocell and 65% viscose. Saying “made with lyocell” is technically incomplete without the rest of the blend: viscose is the majority.

The Twisted-Strap Slip Midi Dress is listed as 40% modal and 60% nylon. Modal is present, but nylon is the larger share. The label is doing its job; we just have to read the whole line.

Does this mean “instead of polyester”?

For the six New In examples above, the current composition records do not list polyester. That is a narrow product fact, not a universal HAE claim. HAE’s wider active catalog also includes some modal- or lyocell-containing blends that list polyester. The honest version is product by product, never a sweeping promise.

Does lyocell or modal automatically mean sustainable?

No single fiber name proves that an entire garment is sustainable. The manufacturer, feedstock, production process, other fibers in the blend, dyeing and finishing, construction, transport, use, care, and end of life can all affect the larger picture. A product-level environmental comparison needs product-level evidence and a clear basis for comparison.

Lenzing publishes specific sourcing, production, certification, and environmental information for its TENCEL™ branded fibers. Those claims should stay attached to verified branded fiber. They should not be copied onto a generic lyocell product or extended to a finished blended garment without supporting documentation.

The FTC Green Guides summary also warns against broad, unqualified claims such as “green” or “eco-friendly.” Specific, substantiated language is more useful anyway. It tells you what is known instead of asking one adjective to do all the work.

A practical label-reading checklist

• Read every listed fiber. Do not stop after the first familiar word.
• Compare the percentages. Is the fiber the majority, a substantial share, or a small addition?
• Separate generic names from brands. Lyocell is a generic name; TENCEL™ is a specific brand.
• Look for product-level proof. Certification or process claims need documentation for the actual input or garment.
• Keep performance questions separate. A composition alone does not guarantee fit, comfort, care, durability, or feel.
• Question broad environmental language. Ask which part of the product the claim covers and what evidence supports it.

A material label is not the whole answer. It is, however, a very good place to begin—especially when we read all of it.
