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

According to the present invention, it is possible to obtain a spun yarn having a soft feel, and also having the functions of high water absorption, quick-drying, and impermeability that cannot be realized only by natural fibers and cellulose fibers, and provides a yarn suitable for clothing applications, especially Spinning of underwear and jerseys and knitted fabrics formed from said spinning. The spun yarn of the present invention is formed by 20-80% by mass of flat multi-lobal cross-section polyester fibers and 20-80 mass% of cellulose-based fibers, wherein the cross-sectional shape of the flat multi-lobal cross-section polyester fibers is It has a flat shape with six or more protrusions on the circumference, and the spun yarn is obtained by blending polyester-based fibers with predetermined flatness and irregularity.

Description

technical field [0001] The invention relates to a spun yarn with good water absorption, quick-drying, anti-permeability and soft hand feeling, in particular to a spinning yarn suitable for clothing applications such as inner shirts, pants and sports Spun yarn for knitted fabrics such as sports shirts and knitted fabrics using the spun yarn. 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. [0004] In addition, a blended yarn ...
