    Abstract: A fiber comprising polyethylene-2,5-furan-dicarboxylate, is prepared by melt spinning in a process wherein a molten composition comprising polyethylene-2,5-furan-dicarboxylate having an intrinsic viscosity of at least 0.55 dl/g, determined in dichloroacetic acid at 25° C., is passed through one or more spinning openings to yield molten threads; wherein the molten threads are cooled to below the melting temperature of the composition to yield spun fibers; and wherein the spun fibers are drawn to a linear density in the range of 0.05 to 2.0 tex per fiber. The invention also proves a fiber comprising polyethylene-2,5-furan-dicarboxylate having a linear density of 0.05 to 2.0 tex, wherein the polyethylene-2,5-furan-dicarboxylate has an intrinsic viscosity of at least 0.45 dl/g, determined in dichloroacetic acid at 25° C.
