    摘要： A nanoweb that contains a plurality of nanofibers wherein the nanofibers contain a fully aromatic polyimide that is characterized by having a crystallinity index (CI) and a degree of imidization (DOI). The product of the DOI and the CI is between 0.08 and 0.25 or above a lower limit to obtain a desired tensile strength and/or toughness. The nanoweb may for example have a tensile strength per unit basis weight of greater than 15 kg/cm2 per gram per square meter unit of basis weight.

    摘要： 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.
