Devices for radiative cooling and optical waveguiding are provided, wherein the devices comprise a fabric including one or more fibers extending for a length in a longitudinal direction and a plurality of void structures positioned within each of the one or more fibers and extended over the length of each of the one or more fibers. Each of the plurality of void structures is configured to scatter at least a portion of an electromagnetic radiation received thereon to thereby radiatively cool the object.

A vinyl chloride-based fiber includes a vinyl chloride-based resin composition. The vinyl chloride-based resin composition includes a vinyl chloride-based resin A and a vinyl chloride-based resin B. The vinyl chloride-based resin A is a copolymer of vinyl chloride and a macromonomer and the vinyl chloride-based resin B is a vinyl chloride-based resin other than the vinyl chloride-based resin A. A method for producing the vinyl chloride-based fiber includes a step of obtaining undrawn yarn by melt-spinning the vinyl chloride-based resin composition.
