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.
Claims6
A wipe cloth weighing from 100 g/m2 to 500 g/m2, wherein the wipe comprises cross-lapped webs formed at least partially of winged-type polymeric fibers with nano-channels between the wings measuring one micron or less, with a filament titer of 1.0 to 10 dtex, the fibers between about 30 and about 100 mm long,
- wherein the cross-lapped webs are entangled either by needle-punching or hydro-entangling.
A wipe cloth weighing from 30 g/m2 to 500 g/m2, wherein the wipe comprises at least one spunbond non-woven web formed at least partially of a continuous winged-type polymeric filament with nano-channels between the wings measuring one micron or less, with a filament titer of 1.0 to 10 dtex,
- wherein the web is hydroentangled.
