Abstract:
A synthetic fiber having(1) an axis, (2) a cross-section perpendicular to said axis, said cross-section having a cross-sectional shape, (3) said cross-sectional shape defines a substantially semi-circular shape, said shape having a center region, a first end region including a first distal tip, and a second end region including a second distal tip, a cross-section length from the first distal tip along the cross-section to the second distal tip, and a cross-section width of said cross-section at the center of said shape cross-section, (4) said first distal tip is separated from said second distal tip by greater than 40 microns, and (5) a ratio of the cross-section length to the cross-section width is greater than 20; wherein said fibers have a lubricant coated thereon comprising 90 weight percent water and 10 weight percent solids component, said solids component comprising 10 weight percent solution of poly 44.1 weight percent polyethylene glycol (400) monolaurate, 44.1 weight percent polyethylene glycol (600) monolaurate, and 1.8 percent 4-cetyl, 4-ethyl morpholinium ethosulfate.
