Abstract
A process for forming a unidirectionally oriented fiber structure formed of high tenacity fibers. A plurality of yarns of high tenacity fibers are supplied, with the yarns being unidirectionally oriented. The yarns are coated with a liquid having a viscosity of about 5 to about 600 centipoises and tension is applied to the yarns. The yarns are passed through a fiber spreading device and the yarns are dried. The yarns are reduced in thickness and increased in width after passing through the fiber spreading device, with the fibers forming the yarns being spread apart, thus providing a relatively thin unidirectionally oriented fiber structure.
