The present invention relates to a high-fastness UV-curable coating method for spun yarn for denim fabric, the method replacing a conventional dyeing process, thereby having limitations in color implementation and providing excellent flame-retardant performance. According to the present invention, the high-fastness UV-curable coating method for spun yarn can be provided, the method using an ultraviolet-curable yarn dyeing technique in which a 100% solid UV resin, rather than a reduction dye and a dye solution used in a conventional dyeing process of spun yarn that can be used for denim fabric, is used so that harmful volatile organic compounds (VOCs) are not emitted, solving environmental problems that occur during manufacturing by not using solvents such as water, and enabling high productivity and energy consumption reduction to be achieved through rapid polymerization.

The present invention may provide a method for high fastness dyeing of a fibrous yarn employing UV curing, wherein, in the method, yarns from general clothing fibers to industrial flame-retardant fibers are dipped in a UV-curable coating liquid to form a thin coating layer thereon, and then the UV-curable coating liquid is cured, and wherein the method not only provides an eco-friendly preparing method, which has an energy reduction rate of about 90% compared with an existing method of thermally curing and coating yarns; causes no wastewater due to the non-use of a medium such as water; has no emission of carbon dioxide by combustion; and can skip a washing process through a high degree of conversion, but also gives various performances by dispersing various functional materials with excellent adhesive strength.
