Why the label says viscose and not bamboo
Short answer: Bamboo is the raw material, not the fibre. Once bamboo has been dissolved and spun into thread, the result is a viscose fibre, and that is the term the labelling rules require.
From plant to fibre
The bamboo is broken down, the cellulose dissolved, and the mass pressed through nozzles into threads. The process is the same as for other viscose.
Why it cannot say bamboo alone
Fibre names are set in legislation, and bamboo is not a fibre name. That is why it says viscose, often with bamboo named as the raw material.
What it does not mean
It does not mean the item is wrongly described or of poorer quality. It is a labelling rule, not a quality judgement.
Lyocell is a different process
Lyocell is made in a closed loop with a different solvent. See bamboo lyocell versus bamboo rayon.
Rayon is the same as viscose
In English viscose is often called rayon. See what is rayon.
