Abstract

Colored, high strength, high modulus p-aramid fibers are prepared by including an organic pigment which is soluble in but not degraded by concentrated sulfuric acid in a p-aramid spinning dope wherein the solvent is concentrated sulfuric acid and spinning the pigment containing dope through an air gap into a coagulation bath and washing and drying the resulting fibers. No colorant particles or agglomerates are visible under an electron microscope at a magnification of 9000 X.
