Inventor(s): Robert Blackwell, Donald Wright and Albert Moorhead
Company: Honeywell International Inc.
A fiber made up of two or more lobes extending from a central core has been patented. The two or more lobes are equally spaced around an outer periphery of the central core. Each lobe has a substantially similar lobal cross-sectional configuration comprising at least three concave portions, at least two convex portions and at least four inflection points along an outer perimeter of each lobal cross-sectional area. A maximum distance between adjacent lobes is located between adjacent areas of the maximum width of each of the adjacent lobes. A cross-sectional periphery of the fiber is free of flat surfaces and consists only of at least three concave portions, at least two convex portions and at least four inflection points of each lobe.
