Claims18
A fiber comprising two or more lobes extending from a central core, wherein the two or more lobes are equally spaced about an outer periphery of the central core, and wherein each lobe has a substantially similar lobal cross-sectional configuration comprising at least three concave portions, at least three convex portions, and at least five inflection points along the outer perimeter of each lobal cross-sectional area.
A fiber comprising two or more lobes extending from a central core, wherein the two or more lobes are equally spaced about an outer periphery of the central core, and wherein each lobe contains three concave portions, at least three convex portions, and at least four inflection points along the outer perimeter of the lobal cross-sectional area;
- wherein the concave portions, the convex portions, and the inflection points along the outer perimeter of the lobal cross-sectional area form a pathway such that a lobe-dissecting line extending outward from a fiber central axis through the lobe moves in an S-shaped pathway to a tip of the lobe.
