ABSTRACT:
A process for producing fiber from polyarylene sulfide, by melt spinning a polyarylene sulfide into a gas, cooling the spun filaments with a blown gas, taking the filaments off at a high speed, storing the spun filaments, drawing the spun filaments in two stages and after treatment stage, and immediately thereafter heat setting the drawn filaments. Fibers produced by the invention have excellent mechanical properties including tensile strength and transverse strength, and the process is very efficient.
