To provide a composite spun yarn and a fiber structure, which can highly maintain moisture absorbing and heat generating property, and a manufacturing method thereof.SOLUTION: A composite spun yarn includes an animal hair fiber and a cellulosic fiber. The animal hair fiber is covered by a fiber including the cellulosic fiber. When the composite spun yarn is 100 mass%, sodium ratio is 0.5 mass% or more, consequently, the composite spun yarn has a moisture absorbing and heat generating property. A fiber structure of the present invention includes the composite spun yarn of the present invention. The composite spun yarn or the fiber structure is subjected to a sodium replacement processing after refining and bleach, dyeing and neutralization soaping steps so that the sodium ratio is 0.5 mass% or more.SELECTED DRAWING: Figure 2 【課題】吸湿発熱性を高く維持できる複合紡績糸、繊維構造物及びこれらの製造方法を提供する。【解決手段】獣毛繊維とセルロース系繊維を含む複合紡績糸であって、獣毛繊維はセルロース系繊維を含む繊維で被覆されており、前記紡績糸を１００質量％としたとき、ナトリウムの割合が０．５質量％以上であり、吸湿発熱性を有する。本発明の繊維構造物は本発明の複合紡績糸を含む。複合紡績糸または繊維構造物は、精練・漂白、染色及び中和ソーピング工程の後に、ナトリウム置換処理を行い、ナトリウムの割合が０．５質量％以上とする。【選択図】図２
