Process for the manufacture of cellulose-based fibres and the fibres thus obtained |
摘要 |
A method for the spinning of a fibre comprising cellulose nano-fibrils being aligned along the main axis of the fibre from a lyotropic suspension of cellulose nano-fibrils, said nano-fibril alignment being achieved through extension of the extruded fibre from a die, spinneret or needle, wherein said fibre is dried under extension and the aligned nano-fibrils aggregate to form a continuous structure and wherein the suspension of nano-fibrils, which has a concentration of solids of at least 7% wt, is homogenised using at least a mechanical, distributive mixing process prior to its extrusion. The fibrils used in this method can be extracted from a cellulose-rich material such as wood. The invention also related to a cellulose-based fibre obtained according to this method and to a cellulose fibre which contains at least 90% wt of crystallised cellulose. |
