Lyocell is an artificial fibre but is of vegetal origin (wood pulp). Therefore, it is considered to be a natural material when processed. This fibre is biodegradable.
In order to obtain Lyocell, wood pulp (cellulose) is extracted and ground. The wood used comes from sustainable forests. The pulp is then heated and dissolved with water and organic solvents. These solvents are non-toxic and 99%% reusable. This is then spun to form Lyocell.
Lyocell's raw material is a healthy material with very little environmental impact. So, it is an ideal alternative to synthetic or animal-derived fillers.
