A manufactured fibre made by processing natural cellulose and forming it into new fibres, such as Lyocell™.
Used by Edexcel and Eduqas
Specification 6.2.5 · Paper 1
Revise: Geographical Origins of TextilesThe cellulose is processed and formed into new fibres, so Lyocell™ is a regenerated fibre rather than a fibre collected directly from the tree.
Component 1
A manufactured fibre made by processing a naturally occurring polymer, such as plant cellulose, and forming it into new fibres.

There is also an important category between a directly harvested natural fibre and a synthetic fibre: regenerated fibres. Their starting material is a natural polymer, but it is processed and re-formed into fibres. Rayon/viscose is therefore associated with plant polymers because of its cellulose source, while the fibre itself is manufactured.
A manufactured fibre made by chemically processing natural cellulose into a new fibre form, such as viscose.
