Abstract
This disclosure relates to articles that comprise polymeric winged fibers. The winged fibers have a high surface area because of their structure, which includes a core surrounded by a plurality of lobes. Channels of one micron or less in width are formed between adjacent lobes to form paths for the capture and/or transport of gases, liquids or particles. The winged fibers are assembled in woven or non-woven fabrics for use in wipes, absorbent pads, composite structures, apparel, outdoor wear, bedding, filtration systems, purification/separation systems, thermal and acoustic insulation, cell scaffolding, and battery membranes.
