To improve a dyeability and wear resistance of a fiber while ensuring an excellent near-infrared reflection performance.SOLUTION: A composite fiber 1 includes a core portion 3 and a sheath portion 5. The composite fiber 1 has a substantially triangular outer shape in a cross section of the fiber, and a length of each side constituting the outer shape is 2 μm or more and 10 μm or less. The core portion 3 has a substantially triangular cross-sectional shape. A length of each side constituting the substantially triangular cross-sectional shape of the core portion 3 is shorter than a length of each side constituting the outer shape of the composite fiber 1, and is 1 μm or more and 5 μm or less. Materials of the core 3 and the sheath 5 are different.SELECTED DRAWING: Figure 2
【課題】優れた近赤外線の反射性能を確保しつつ、染色性を向上させ、かつ耐摩耗性も向上させる。【解決手段】複合繊維1は、芯部3と、鞘部5と、を備えてなる。複合繊維1は、繊維横断面の外形が略三角形であり、かつ、外形を構成する各辺の長さが2μm以上10μm以下である。芯部3が略三角形の断面形状を有する。芯部3の断面形状の略三角形を構成する各辺の長さは、複合繊維1の外形を構成する各辺の長さよりも短く、かつ1μm以上5μm以下である。芯部3と鞘部5は材質が異なる。【選択図】図2
