ABSTRACT:
Process and apparatus for the manufacture of polyolefin-containing fibers, preferably high-smectic content polyolefin-containing fibers, wherein a spin height of less than about 4 meters is utilized at spinning speeds of at least about 500 m/min. Further, guidance wings and/or an exhaust extensions are disclosed for various spinning systems to assist in the quenching of fibers. Fibers produced by the invention, preferably skin-core fiber, enable the production of nonwoven materials having excellent properties.
