Dissolution, crystallisation and regeneration of cellulose in Nmethylmorpholine N-oxyde
Résumé
Mixtures of N-methylmorpholine N-oxyde (NMMO) and water are direct solvents for cellulose, used for processing fibres (Lyocell process). The objective of this work is to study three aspects of the preparation of cellulose objects from NMMO-water solutions, the NMMO-water phase diagram in order to follow the dissolution-swelling path, the crystallisation of the cellulose solution that may occur under cooling and the regeneration of the cellulose from a solution.
