SPUN YARN, MANUFACTURING METHOD THEREOF, AND FABRIC INCLUDING THE SAME

To provide a spun yarn capable of obtaining a fabric having soft feeling, excellent tension, stiffness, and water-absorbing quick-drying property, a manufacturing method thereof, and the fabric including the same.SOLUTION: The invention is a spun yarn including 80 mass% or more of natural cellulosic fibers and regenerated cellulosic fibers. The spun yarn consists of a twistless fiber group in twistless state and a winding fiber group winding around the twistless fiber group, and includes 15 mass% or more and less than 85 mass% of the natural cellulosic fibers and more than 15 mass% and 85 mass% or less of the regenerated cellulosic fibers. Inner layer mixing ratio of the regenerated cellulosic fibers is higher than outer layer mixing ratio on a cross section of the spun yarn. The spun yarn can be manufactured by feeding a sliver including 15 mass% or more and less than 85 mass% of the natural cellulosic fibers and more than 15 mass% and 85 mass% or less of the regenerated cellulosic fibers in a draft zone, drafting the sliver, spinning the drafted sliver under a condition of nozzle pressure at 0.40 to 0.60 MPa, and winding up.SELECTED DRAWING: Figure 1 【課題】ソフトな風合いを有しつつ、ハリとコシ及び吸水速乾性が良好である布帛が得られる紡績糸、その製造方法及びそれを含む布帛を提供する。【解決手段】本発明は、天然セルロース系繊維及び再生セルロース系繊維を８０質量％以上含む紡績糸であって、無撚状態の無撚繊維群と、無撚繊維群の周囲に巻き付いている巻き付き繊維群で構成され、天然セルロース系繊維を１５質量％以上８５質量％未満、及び再生セルロース系繊維を１５質量％超８５質量％以下含み、紡績糸の断面において、再生セルロース系繊維の内層混用率が外層混用率より高い紡績糸に関する。前記紡績糸は、渦流空気精紡において、天然セルロース系繊維を１５質量％以上８５質量％未満、再生セルロース系繊維を１５質量％超８５質量％以下含むスライバーをドラフトゾーンに供給しドラフトし、ノズル圧が０．４０～０．６０ＭＰａの条件で紡出し、巻き取ることで作製することができる。【選択図】図１
