| titleOfInvention | Method of manufacturing wholly aromatic polyamide filament and wholly aromatic polyamide filament manufactured thereby |
| abstract | Disclosed are a method of manufacturing wholly aromatic polyamid filaments and wholly aromatic polyamid filaments produced by the same. The present inventive process comprises control of a timing for introducing wholly aromatic polyamid polymer into an extruder for preparation of a spinning dope based on particle size and/or inherent viscosity (IV) of the polyamid polymer. The present invention can significantly reduce brittleness of the wholly aromatic polyamid polymer due to a sulfuric acid solvent during preparation of the spinning dope so as to improve strength and, especially, side impact strength of the wholly aromatic polyamid filaments and can also use even polymers with lower IVs which are necessarily generated during the polymerization, thereby reducing production costs of the polyamid filaments. |
