Method for producing wholly aromatic liquid crystal polyester fiber with improved spinnability |
| abstract |
The present invention relates to a method for producing a wholly aromatic liquid crystal polyester fiber having improved spinnability, and more particularly, to After adding 1.08 to 1.12 equivalents of acetic anhydride to the raw material monomer and performing solid-state polycondensation to pelletize the resin, 0.5% to 2% of entanglement-improving emulsion and 0.5% to A method for producing wholly aromatic liquid crystal polyester fibers by melt spinning under the emulsification condition of 2% high-temperature silicone spinning emulsion. |
