Summary: | Various embodiments of a process for making fibers comprising a high heat polymer are provided. In one embodiment, a process for producing polymer fiber includes extruding molten polymer having a melt temperature ranging from about 180-500° C., passing the molten polymer through a plurality of openings of a spinneret to produce a fiber bundle, and contacting the fiber bundle with a cooling medium having a substantially uniform flow distribution across the width of the fiber bundle where the cooling medium has a temperature that ranges from about 0° C. to about 80° C. |
