This multilayered spun yarn (20) comprises a core component (21) constituted of para-based aramid fiber yarns obtained by stretch breaking spinning and a sheath component (22) including polybenzimidazole fibers, wherein the sheath component (22) has been obtained by mix spinning so as to include the polybenzimidazole fibers and meta-based aramid fibers, the polybenzimidazole fibers and the meta-based aramid fibers having at least two different colors. In the multilayered spun yarn (20), the polybenzimidazole fibers and the meta-based aramid fibers apparently differ in color tone. This heat-resistant fabric is obtained using the multilayered spun yarn, and this heat-resistant protective garment is obtained using the heat-resistant fabric. Thus, a multilayered spun yarn which renders color matching easy and has not only high laundering resistance but also high heat resistance and flame retardancy, a heat-resistant fabric obtained using the multilayered spun yarn, and a heat-resistant protective garment are provided. |
