Embodiment 1

[0093] A flat multi-lobed cross-section polyester system with a single fiber fineness of 1.7 dtex, a titanium oxide content of 0.3% by mass, a flatness of 2.1, a degree of irregularity of 2.7, a protrusion ratio of 0.8, and a cross-sectional shape of 8 protrusions Fiber (fiber length 51mm) 20% by mass and rayon fiber (fiber length 51mm) with a single fiber fineness of 1.7dtex 80% by mass were blended to obtain a spun yarn with an English cotton count of 40s with a twist coefficient K = 3.5 . This spun yarn was used for warp and weft, and a flat fabric having a warp density of 110 threads / 2.54 cm and a weft density of 76 threads / 2.54 cm was obtained using an air-jet loom. Table 1 shows the fiber configuration of the spun yarn, and Table 2 shows the evaluation results.

Embodiment 2

[0095] A flat multi-lobed cross-section polyester system with a single fiber fineness of 1.7 dtex, a titanium oxide content of 0.3% by mass, a flatness of 2.1, a degree of irregularity of 2.7, a protrusion ratio of 0.8, and a cross-sectional shape of 8 protrusions 50% by mass of fiber (fiber length: 51 mm) and 50% by mass of rayon fiber (fiber length: 51 mm) having a single fiber fineness of 1.7 dtex were blended to obtain a spun yarn with an English cotton count of 40 s with a twist coefficient K = 3.5 . This spun yarn was used for warp and weft, and a flat fabric having a warp density of 110 threads / 2.54 cm and a weft density of 76 threads / 2.54 cm was obtained using an air-jet loom. Table 1 shows the fiber configuration of the spun yarn, and Table 2 shows the evaluation results.

Embodiment 3

[0097] A flat multi-lobed cross-section polyester system with a single fiber fineness of 1.7 dtex, a titanium oxide content of 0.3% by mass, a flatness of 2.1, a degree of irregularity of 2.7, a protrusion ratio of 0.8, and a cross-sectional shape of 8 protrusions Fiber (fiber length 51mm) 80% by mass and rayon fiber (fiber length 51mm) with a single fiber fineness of 1.7dtex 20% by mass were blended to obtain a spun yarn with an English cotton count of 40s at a twist coefficient K = 3.5 . This spun yarn was used for warp and weft, and a flat fabric having a warp density of 110 threads / 2.54 cm and a weft density of 76 threads / 2.54 cm was obtained using an air-jet loom. Table 1 shows the fiber configuration of the spun yarn, and Table 2 shows the evaluation results.

Abstract

[Problem] To provide: a spun yarn which has not only a soft texture but also functions that cannot be attained by a natural or cellulosic fiber alone, namely high water absorption, quick drying property and non-see-through property, and which is suitable for clothing, particularly for inner shirts or sport shirts; and a woven or knitted fabric comprising the same. [Solution] A mixed spun yarn which comprises 20 to 80 mass% of a polyester-based fiber having a flat multi-lobe section and 20 to 80 mass% of a cellulosic fiber, wherein: the cross section of the polyester-based fiber has a flat shape which has six or more protrusions on the circumference; and the flatness degree and modification degree of the cross section are prescribed.

Description

technical field [0001] The invention relates to a spun yarn with good water absorption, quick-drying, impermeability and soft hand feeling, and in particular to a spinning yarn suitable for clothing applications, such as inner shirts, pants and sweatshirts. Spinning (spunyarn) of knitted fabrics for (sports shirts) and other uses and knitted fabrics made using the spun yarns. Background technique [0002] For clothing applications such as inner shirts, shorts, and sweatshirts, research has been conducted on the water absorption, quick-drying, soft feel, and impermeability of polyester materials, and spinning and Braid. [0003] For example, a spun yarn in which a blending ratio of 3 to 4 types of polyester-based modified cross-section short fibers is 15 to 20% by weight or more has been proposed (see Patent Document 1). However, in this proposal, since the spun yarn is composed of only synthetic fibers, there is a problem of insufficient water absorption and soft touch. ...
