Abstract
High strength, high modulus, continuous filament aromatic polyamide yarns are stretch broken under high tension while being sharply deflected in a lateral direction by mechanical means to provide a sliver which is processed by conventional means to a high strength, high modulus spun yarn. The broken ends of the fibers are highly fibrillated to fibrils having lengths of 50-350 times the diameter of the unfibrillated portion of each fiber.
