Method of wet spinning precursor fibers comprising lignin and gelling hydrocolloid, and precursor fibers therefrom |
| abstract |
The present disclosure relates to a method for the production of precursor fiber for the production of carbon fiber, comprising the steps:a) providing a spinning dope comprising a lignin and a gelling hydrocolloid dispersed in aqueous alkaline solution (s201);b) extruding the spinning dope through a spinning nozzle to provide an initial fiber (s203); andc) passing the initial fiber through a first coagulation liquid to provide the precursor fiber (s205);wherein the first coagulation liquid is arranged to effect gelling of the gelling hydrocolloid by regulation of pH and/or ionicity.The disclosure further relates to precursor fibers and carbon fibers produced by the method above. |
