<p>The present invention relates to a coil spring yarn having excellent elasticity and a method for manufacturing the coil spring yarn. The coil spring yarn having excellent elasticity includes: a core thread (10) twisted to have a coil spring shape; and an auxiliary thread (20) having a coil spring shape and a coil (21) disposed between coils (11) of the core thread (10), the auxiliary thread (20) being provided with a dissolution thread dissolved in a solvent. When the auxiliary thread (20) is wound around an outer circumference of the core thread (10) in a coil spring shape, and the core thread (10) and the auxiliary thread (20) are simultaneously twisted, the coil (21) of the auxiliary thread (20) moves between the coils (11) of the core thread (10). Also, according to an elastic fabric of the present invention, a raw fabric woven by using the coil spring yarn is immersed in the solvent to dissolve the auxiliary thread (20) so that the elastic fabric has excellent elasticity by the core thread (10) twisted in the coil spring shape. The elastic fabric of the present invention may be improved in elasticity and restoring performance.</p> |
