| 发明名称 | Method for spinning anionically modified cellulose and fibres made using the method | ||
| 摘要 | The present invention is directed towards a method for spinning anionically modified cellulose comprising the steps of: (a) preparing a suspension of the anionically modified cellulose in a continuous phase; (b) subjecting the suspension to high shear rate; (c) performing spinning by extruding the cellulose suspension through a spinneret into a spinbath comprising a cationic complexing agent, and (d) isolating the sun fibers from the spin bath; as well as fibers obtained based on the method of the invention and paper or board products derived from such fibers. | ||

| 主权项 | 1. A method for spinning fibres from anionically modified cellulose to produce spun fibres, comprising the steps of: (a) preparing a suspension of the anionically modified cellulose in a continuous phase; (b) subjecting the suspension to high shear rate; (c) performing spinning by extruding the cellulose suspension through a spinneret into a spin bath comprising a cationic complexing agent, and (d) isolating the spun fibres from the spin bath. | ||
