Feedstock

Tencel is one of the most sustainable fibres available on the market and is produced by Austrian company Lenzing. This 100% Biobased fibre is created using Eucalyptus and Spruce trees which are harvested responsibly through Lenzing’s FSC & PEFC certified supply chain. Lenzing ensure that 100% of the tree is used with 40% becoming pulp, 50% burnt for energy and the remaining 10% is used in other processes, such as their collaboration with DuPont to make a sweetener used by Diabetics.

Manufacturing Process

The process to create this fibre begins with the harvested Eucalyptus and Spruce trees being debarked and converted into chips. The chips then enter a digester which harvests the cellulose using an organic solvent from which a pulp is formed.  This organic, non-toxic compound is called N-Methylmorpholine N-oxide (NMMO) and replaces the sodium hydroxide (caustic soda) used in traditional viscous/modal production.

The pulp is then dissolved in a batch of the organic solvent, which turns the pulp into a honey like substance, which is then extruded into a staple fibre before being spun into a yarn. The organic solvent is easy to filter and re-use, creating an almost completely closed loop system, where over 99% of the water and solvent is recovered and reused.
