The method of claim 8, wherein the continuous multi-component fibers are comprised of fibers selected from the group consisting of polyester, polyamide, polyolefin, polyacrylic, polyaramide, polyurethane, polylactic acid, and combinations thereof. 10. The method of claim 9, wherein the continuous multi-component fibers are comprised of polyamide and polyester, wherein the polyester is selected from the group consisting of polyethylene terephthalate, polytriphenylene terephthalate, polybutylene terephthalate, and combinations thereof, and wherein the polyamide is selected from the group consisting of nylon 6, nylon 6,6, and combinations thereof. 11. The method of claim 10, wherein the continuous multi-component fibers are comprised of polyethylene terephthalate and nylon 6,6. 12. The method of claim 11, wherein the continuous multi-component fibers are comprised of polyethylene terephthalate and nylon 6,6, wherein polyethylene terephthalate comprises approximately 65% of the continuous multi-component fibers, and wherein nylon 6,6 comprises approximately 35% of the continuous multi-component fibers. 13. The method of claim 8, wherein the improved aesthetic and performance characteristics are selected from the group consisting of improved flexibility, drape, softness, thickness, moisture absorption capacity, moisture vapor transmission rate, cleanliness, and combinations thereof. 14. The product of the method of claim 8. 15. A method for providing a spun-bonded nonwoven fabric comprised of continuous multi-component fibers that are at least partially split along their length and that exhibits improved aesthetic and performance characteristics, the method comprising the sequential steps of: (a) providing a spun-bonded nonwoven fabric comprised of continuous multi-component fibers which have been at least partially longitudinally split along their length; (b) dyeing or printing the spun-bonded nonwoven fabric; (c) subjecting the spun-bonded nonwoven fabric to an air impingement surface treatment to create a treated spun-bonded nonwoven fabric exhibiting a fabric weight-to-Bending Stiffness ratio of about 187 or greater, wherein the Bending Stiffness is measured by the Kawabata Pure Bending Tester (KES FB2); and (d) further printing, dyeing, or treating the spun-bonded nonwoven fabric with a face-finishing process. 16. The method of claim 15, wherein the continuous multi-component fibers are comprised of fibers selected from the group consisting of polyester, polyamide, polyolefin, polyacrylic, polyaramide, polyurethane, polylactic acid, and combinations thereof. 17. The method of claim 16, wherein the continuous multi-component fibers are comprised of polyamide and polyester, wherein the polyester is selected from the group consisting of polyethylene terephthalate, polytriphenylene terephthalate, polybutylene terephthalate, and combinations thereof, and wherein the polyamide is selected from the group consisting of nylon 6, nylon 6,6, and combinations thereof. 18. The method of claim 17, wherein the continuous multi-component fibers are comprised of polyethylene terephthalate and nylon 6,6. 19. The method of claim 18, wherein the continuous multi-component fibers are comprised of polyethylene terephthalate and nylon 6,6, whe
