Abstract
A process for preparing high initial modulus and high tensile strength polyamide fibers is described. The process comprises complexing the polyamide with a Lewis acid, dry-jet wet spinning the complexed fibers, drying the spun fibers for a period of time, drawing the fibers, and soaking the fibers in solvent to remove the Lewis acid. High molecular weight nylon 6,6 fibers prepared according to the described process show initial moduli of up to 30.1 GPa and tenacities of up to 2.5 GPa.
