The current invention relates to a process for the manufacture of a polyurethane elastomer fiber in which a) a polymer diol and a substance that reacts to a polymer diol are converted to an OH-terminated prepolymer; b) the OH-terminated prepolymer with one diisocyanate is converted to an isocyanate-terminated prepolymer; c) the isocyanate-terminated prepolymer with one chain extension, possibly one chain stopper, and possibly additional additives, is converted to a polyurethane elastomer; and d) the polyurethane elastomer is spun to a fiber whereby less than 15% by weight of additional polyurethane elastomers are contained in the fiber. The current invention furthermore relates to a polyurethane elastomer fiber obtained using a process of this type used to manufacture textiles, such as for example, woven or knitted, as well as the use of a polyurethane elastomer for the manufacture of such a fiber.
