The functional composite fiber comprises a plurality of the T-lobes connected with each other at their bases, wherein the caps of the T-lobes contain a component, and their bases T-lobes contain the component and an additive. The additive is not exposed on the surface of the fiber thereby preventing post-manufacturing abrasion of the spinning machine.
