Abstract: Disclosed is a process for the manufacture of an elastic polyurethane fiber, including mixing one component selected from among polystyrene polymers or polystyrene copolymers having a number average molecular weight of 50,000–500,000 with polyurethane having a number average molecular weight of 15,000–100,000, to prepare a polymer mixture, which is then spun. The polyurethane elastic fiber made by the method is also provided, which is greatly increased in heat set properties, with a very low rate of change of fundamental properties as the results compared with conventional elastic polyurethane fibers. Hence, the elastic polyurethane fiber can be directly applied for preparation of end products requiring superior heat set properties with no change of conventional conditions of the process.

Abstract: Disclosed is a fluorescent elastic yarn and method for producing the same. The fluorescent elastic yarn which is finished with the spinfinish oil containing the fluorescent agent can fluoresce sufficiently to allow a fine elastic yarn to be seen by the naked eye when ultraviolet light is irradiated to the fluorescent elastic yarn. Therefore, the fluorescent elastic yarn of the present invention is advantageous in that CSY (Core spun yarn) producers are able to identify its presence inside of the hard fiber covering it more easily and timely and thus minimize the numbers of inferior CSY products which are not spun with elastic yarn strands.
