Abstract

A method and device for the production of polymer filaments with a diameter of less than one micron. A plurality of polymer components are extruded through a spin pack and then attenuated using gas flows which are accelerated to achieve high velocity by means of a converging, diverging nozzle. The plurality polymer components may be extruded in an islands in the sea or segmented pie configuration. As a result of the high velocity gas flow, the plural components are split apart into their individual components resulting in filaments and fibers having a diameter or minor dimension of less than one micron.
