Capillary groups for a spinnerette include sheath and core openings to produce a spun bi-component fiber having a trilobal or triangular profile. A triangular or trilobal configured outer sheath arrangement surrounds a trilobal cross-section core which is alternatively oriented with its lobes toward the sheath tips or rotated 60 degrees thereto. Different sheath arrangements are also disclosed for producing bi-component sheath/core trilobal fibers with and without voids. <IMAGE> |
