<p>Cellulose formate fibre and a cellulose fibre regenerated from cellulose formate are disclosed. The fibres have high toughness and modulus properties combined with improved elongation at break and energy at break. Specifically, their elongation at break is higher than 6 %. Methods for producing said fibres are also disclosed. The cellulose formate fibre is produced by dry-jet-wet spinning a cellulose formate liquid-crystal solution followed by a coagulation step and a neutral washing step both performed in acetone. The regenerated cellulose fibre is produced by treating a cellulose formate fibre in an aqueous solution with a high soda concentration. The spinning and regenerating methods may be performed sequentially and continuously. Furthermore, reinforcing assemblies based on such fibres, and articles reinforced using said fibres or assemblies, particularly tyre casings, are disclosed.</p> |
