A method of producing a multicomponent trilobal fiber includes providing a trilobal capillary defining three legs, three apexes and an axial center, directing a first molten polymer composition to the axial center and presenting a second molten polymer composition to at least one of the apexes. The fiber produced has a trilobal core defining an outer core surface and a sheath abutting at least about one-third of the outer core surface.
