METHOD FOR STABILIZING LIGNIN FIBER FOR FURTHER CONVERSION TO CARBON FIBER |
| 摘要 |
A method for producing a stabilized lignin fiber from softwood alkaline lignin by heat treatment in the absence of oxidant is disclosed. The stabilized lignin fiber can be further treated to obtain carbon fiber. |

1. Method of producing a stabilized lignin fiber comprising the following steps:
a) providing fractionated and/or unfractionated softwood alkaline lignin; b) spinning of the material obtained by step (a), whereby a lignin fiber is obtained; and c) stabilizing of the lignin fiber under inert conditions. |
