CA 2125878

A cellulose formate-based composition for preparing fibres or films, comprising one or more compounds selected from the group consisting of alkylsulphoxides, lactams, acyclic amides and cyclic urea derivatives as the solvent. A method for preparing said fibres and films, and a regenerated cellulose fibre with a degree of formate group substitution lower than 3 %, for use in textile applications or in reinforcing tyre treads, are also disclosed.

Composition à base formiate de cellulose, susceptible de donner des fibres ou des films, comportant comme solvant un ou plusieurs composés choisis dans le groupe constitué par les alkylsulfoxydes, les lactames, les amides acycliques, les dérivés cycliques de l'urée. Procédé pour obtenir ces fibres et ces films. Fibre en cellulose régénérée dont le degré de substitution en groupes formiate est inférieur à 3 %. Cette fibre peut être utilisée pour applications textiles ou pour renforcer des enveloppes de pneumatiques.
