Fiberfill and/or multi-void fibers are identified and/or differentiated by one or more voids being partially filled with a differentiating characteristic that is a protuberance of characterizing polymer material. This material may be the same or different from that of the rest of the fiber. The protuberance is provided by appropriate adjustment of the spinning capillary, i.e., during extrusion to form the fiber.
