Lyocell fibres The lyocell process is based on the high cellulose solubilisation by amine solvents in the presence of water. Manufacturing reactions and structure of oxidised NMM and cellulose solubility in NMMO * x H2O in dependence on water content are shown in Figure 1. The system dissolutes more than 10 % of cellulose at
