Abstract
Preparation of a novel polyester fiber, such as a poly(ethylene terephthalate) fiber, having at least one continuous groove wherein the surface of the groove is rougher than the surface outside the groove is accomplished through a drafting process involving surface hydrolysis. The fibers have improved cover, softness, and wetting characteristics.
