Abstract: An object is to provide a fiber that absorbs heat with good efficiency, has excellent transparency and heat-retaining properties, and does not compromise the design characteristics of a textile product, and to provide a textile product in which the fiber is used. Hexaboride nanoparticles, a dispersion medium, and a dispersion agent for dispersing the nanoparticles are mixed together. The mixture is dispersed and dried to obtain a dispersion powder. The resulting dispersion powder is added to thermoplastic resin pellets, uniformly mixed, and thereafter melted and kneaded to obtain a master batch containing a heat-absorbing component. 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.

Abstract: An inexpensive fiber that has heat retaining properties, satisfactory weather resistance and heat absorption efficiency, and includes a heat absorbing material having excellent transparency; and a fiber article that uses the fiber. A particle dispersion of Cs0.33WO3 is obtained by mixing Cs0.33WO3 microparticles, toluene, and a microparticle dispersing agent to create a liquid dispersion, and then removing the toluene. The particle dispersion is added to and uniformly mixed with pellets of polyethylene terephthalate resin, after which the mixture is extruded, the strands thus obtained are formed into pellets, and a master batch including Cs0.33WO3 microparticles is obtained. This master batch is mixed with a master batch to which inorganic microparticles have not been added, and the mixture thus obtained is melt spun and stretched to manufacture a polyester multifilament yarn. The polyester multifilament yarn is cut, polyester staple fibers are created, and a spun yarn is manufactured.
