The master batch containing a heat-absorbing component is mixed with a similarly prepared master batch to which inorganic nanoparticles has not been added, and the mixture is melted, spun, and drawn to manufacture a multifilament yarn. The multifilament yarn is cut to fabricate staples, and the staples are used to manufacture a spun yarn having heat-absorbing effects.
