Viscose from bamboo, bamboo lyocell, bamboo linen: what the names actually mean
Walk through any baby section and you will see “bamboo” on the tag. Most of the time that word is doing something the law does not allow it to do. Three genuinely different fabrics get sold under it, they are made by different processes, and in Canada only one of them may actually be called bamboo.
This is not a technicality we invented to sound careful. It is written down by the Competition Bureau, and it is the reason our own labels read “viscose from bamboo” rather than the shorter, prettier word.
The rule, in the Bureau's own words
Canada's Competition Bureau publishes specific guidance on labelling textile articles derived from bamboo. The core sentence:
“Bamboo is not an acceptable generic name for a textile fibre unless bamboo fibre has been mechanically processed from natural bamboo fibre.”
For everything else — which is nearly all of it — “the proper generic name will vary depending on which particular cellulose process was used.” The acceptable names are the process name followed by “from bamboo”: rayon from bamboo, viscose from bamboo, modal from bamboo, lyocell from bamboo.
So the distinction is not marketing preference. It is the difference between a compliant label and a non-compliant one.
The three fabrics
1. Viscose from bamboo — the common one
Bamboo is pulped, dissolved in a chemical bath, and regenerated as a fibre. The result is a regenerated cellulose fibre: soft, fluid, breathable, with excellent drape. Almost every “bamboo” baby garment on the market is this.
The chemistry matters for what you can honestly claim about it. As the Bureau puts it, the transformation process that creates rayon “contains no trace of the bamboo plant or its antimicrobial properties.” Raw bamboo does have antimicrobial and biodegradable properties. The fabric made from it, by this process, does not carry them through.
That is why you will never see us claim our fabric is naturally antibacterial. It would be a claim about a plant, applied to a fibre that is chemically several steps removed from it.
2. Lyocell from bamboo — a different solvent process
Lyocell is also regenerated cellulose, but made with a different solvent system, typically run as a closed loop that recovers and reuses the solvent. It tends to be stronger when wet and is often marketed as the more environmentally considered route.
Under Canadian labelling it is still not “bamboo”. It is lyocell from bamboo — a distinct generic name, because a distinct process was used. If a label says “bamboo lyocell” it is at least naming the process, which puts it ahead of a label that just says bamboo.
3. Bamboo linen — the rare one, and the only true “bamboo”
This is the exception the Bureau carves out. Bamboo may be called bamboo when the fibre “has been mechanically processed from natural bamboo fibre, similar to the process for making flax into linen-like fabrics.”
Mechanically processed means crushed, treated with natural enzymes, and combed out into fibres — no dissolving, no regeneration. The result behaves like linen: textured, crisp, strong, and it softens with washing rather than starting soft. It is labour-intensive and expensive, which is why it is uncommon and almost never what is in a soft baby sleeper.
If a garment is genuinely soft and silky against the skin from the first wear, it is very unlikely to be bamboo linen.
A quick way to read a label
- “Viscose from bamboo” / “rayon from bamboo” — correctly labelled regenerated cellulose. This is the standard, compliant description.
- “Lyocell from bamboo” — correctly labelled, made by a different solvent process.
- “Bamboo” alone, on a soft, drapey fabric — almost certainly viscose that has not been labelled properly.
- “100% bamboo” on a silky knit — same problem, stated more confidently.
The Bureau notes these fabrics are “often misrepresented as ‘bamboo’ without any mention of rayon or viscose,” and advises consumers to “be wary of other green or health-related claims associated with so-called ‘bamboo fabric’.” If you think a label is wrong, the Bureau asks that you report it with product details and photos.
Does any of this change how the fabric feels?
Honestly — for viscose and lyocell, not dramatically. Both are soft, breathable, and drape well. The differences show up in wet strength, in how the fibre is produced, and in what a brand can defensibly say about it.
What the naming does change is how much you can trust everything else on the tag. A brand that gets the fibre name wrong — the one thing that is written into federal regulation — has told you something about how carefully it treats its other claims.
What we use, and what we call it
Wame sleepwear is 95% viscose from bamboo and 5% spandex, knit as a 250 GSM single jersey. We call it viscose from bamboo everywhere — on the label, on the product page, in this article — because that is the generic name the process requires.
We do not claim it is antibacterial. We do not claim it is naturally anything. Our fabric specification requires OEKO-TEX Standard 100 Class I certification, and independent third-party testing will be completed before anything is offered for sale.
Designed in Alberta, Canada.
