Very Cooling and soft on the skin. Lyocell is plant-based with natural feel and desirable properties. The internal structure of the fibre is more uniform which further improves its ability to absorb water. Lyocell is a plant-based fibre as viscose and modal, but it is made using a slightly different process. Lyocell production uses a different solvent to extract the cellulose from the wood: sodium hydroxide (caustic soda) is replaced by a non-toxic organic compound with the catchy name N-Methylmorpholine N-oxide (NMMO for short). This organic solvent is easier to filter and re-use in a closed loop, which is better for the environment.
