Aramid Fiber, method of manufacturing Aramid Fiber, bulletproof fabric, and method of manufacturing bulletproof fabric

摘要

PURPOSE: A method for manufacturing aramid fiber is provided to optimize drying process and to improve bulletproof property. CONSTITUTION: A method for manufacturing aramid fiber comprises: a step of polymerizing an aromatic diamine and aromatic diacid halide to prepare aromatic polyamide polymers; a step of dissolving the aromatic polyamide polymers in a solvent to obtain a spinning dope and spinning to prepare a filament; and a step of drying the filament.
