Summary:PROBLEM TO BE SOLVED: To provide a novel spun yarn capable of providing a long-lasting excellent heat insulation effect irrespective of weather to a fabric as well as wearing durability, warm feeling and anti-pilling properties, and a fabric including the spun yarn.SOLUTION: The composite bundle spun yarn is formed by including a synthetic fiber filament containing far infrared radiation fine particles in a core part and hygroscopic and exothermic staple fibers in a sheath part, and has a core-sheath mass ratio (core/sheath) in a range of 20/80-60/40. It is preferable that the hygroscopic and exothermic staple fiber is a lyocell staple fiber. 【課題】布帛に対し、天候に左右されず持続性ある優れた保温効果は勿論のこと、着用耐久性、ウォーム感さらには抗ピリング性などをも付与できる新規な紡績糸と、その紡績糸を用いた布帛とを提供することを目的とする。【解決手段】遠赤外線放射性微粒子を含有する合成繊維フィラメントを芯部に配し、吸湿発熱性短繊維を鞘部に配してなる複合結束紡績糸であって、芯鞘質量比率(芯/鞘)が20/80〜60/40の範囲にあることを特徴とする複合結束紡績糸。本発明では、吸湿発熱性短繊維として、リヨセル短繊維が好適である。【選択図】なし
