Abstract
Spinnerette including a plate including a plurality of capillaries which have capillary ends with dividers which divide each capillary end into a plurality of openings, and a process of making polymeric fiber. The process includes passing a molten polymer through a spinnerette comprising a plurality of capillaries which have capillary ends with dividers which divide each capillary end into a plurality of openings so that the molten polymer is formed into separate polymeric fibers for each opening or the molten polymer is formed into partially split fiber for each capillary, and quenching the molten polymer to form polymeric fiber.
