<p>Improved fibers and a process for making oriented rigid rod polymer fibers (e.g. aramid) having improved properties including compressive strength and/or a substantially regular microstructure across a cross-section of oriented fiber where such improved fibers may be produced in a dry jet-wet spinning process utilizing large diameter spinneret orifices with long air gaps and increased pre-coagulation drafting.</p> |
