Problems solved by technology

[0011] Moreover, woven fabrics made of synthetic fibers are disadvantageous because the water absorption, especially sweat absorption, of synthetic fiber woven fabrics is inferior to that of woven fabrics made of natural fibers such as cotton fibers

example 1

[0116] Polyethylene terephthalate resin is formed by melt-extrusion through 30 melt spinning holes at a temperature of 300°C. These holes are formed in the melt spinneret and have corresponding figure 1 The hole shape of the cross-sectional profile of the wire shown, on each side part of the profile, the profile has 4 arc-shaped protrusions and 3 constrictions formed between the arc-shaped protrusions, which are formed in the shape of the On both sides of the longitudinal centerline. The extruded filament melt stream is wound up at a winding speed of 4000 m / min, while the melt stream is cooled and solidified. The finally formed stretched multifilament yarn was directly stretched at a temperature of 97°C at a draw ratio of 1.3 without being wound, thereby preparing a stretched multifilament yarn having a yarn count of 84 dt / 30 filaments. The monofilament of multifilament has figure 1 In the cross-sectional profile shown, the flatness of the cross-sectional profile is 3.2, and the...

example 2

[0145] With the exceptions shown below, the plain weave of the flat multifilament was produced and tested by the same procedure as in Example 1.

[0146] In the cross-sectional profile of the flat monofilament, the number of arc-shaped protrusions was changed from 4 to 3, and the number of constrictions was changed from 3 to 2 at each side portion of the longitudinal center line of the flat profile.

[0147] The flatness (B / C1) of the flat cross-sectional shape is 3.2, the ratio (C1 / C2) is 1.2, and the cover factor of the plain weave is 1782.

[0148] The test results are shown in Table 1.

example 3

[0164] The polyethylene terephthalate resin containing 2.5% by mass of a delustering agent composed of titanium dioxide is formed by melt-extrusion through 30 melt spinning holes at a temperature of 300°C, and these holes are formed in the melt spinning Head and has corresponding to figure 1 The hole shape of the cross-sectional profile of the wire shown, on each side part of the profile, the profile has 4 arc-shaped protrusions and 3 constrictions formed between the arc-shaped protrusions, which are formed in the shape of the On both sides of the longitudinal centerline. While condensing and solidifying the melt stream, the extruded filament melt stream is wound up at a winding speed of 4000 m / min. The finally formed drawn multifilament was drawn directly without being wound at a temperature of 97°C at a draw ratio of 1.3, thereby preparing drawn multifilament with a yarn count of 84dt / 30 filaments. The monofilament of multifilament has figure 1 In the cross-sectional profile s...

Abstract

A flat multifilament yarn woven fabric having low air permeability and excellent see-through properties, and water or sweat absorption, comprising multifilament yarns as warp and / or weft yarns composed of A plurality of artificial monofilaments are formed, the artificial monofilaments have a flat cross-sectional profile, on both sides of the longitudinal centerline of the flat cross-sectional profile of each artificial monofilament, at least three protrusions per side portion from the longitudinal center Line protruding outwards, at least two constrictions formed between the protrusions of each side part are almost symmetrically shaped with respect to the longitudinal center line, the cross-sectional profile has a flatness of 2 to 6, which is determined by the cross-sectional profile at the longitudinal center The ratio (B / C1) of the maximum length (B) in the thread direction to the maximum width (C1) of the cross-sectional profile in the direction perpendicular to the longitudinal centerline (B / C1) indicates that the woven fabric has a cover factor of 800 to 3500.

Description

Technical field [0001] The invention relates to a flat multifilament yarn woven fabric. In particular, the present invention relates to a woven fabric including multifilament yarns, which are composed of a plurality of rayon monofilaments with a flat cross-sectional shape, and each side portion of the monofilament has two or more constrictions and exhibits softness. Hand feel, actually high water absorption, abrasion resistance and anti-see-through properties. Background technique [0002] Currently, sports clothing and uniforms use different types of woven fabrics with insufficient air permeability. As low-air permeability woven fabrics, known are high-density woven fabrics formed of synthetic fibers, for example, polyester or polyamide fibers, and coated woven fabrics with resin coatings formed on the woven fabrics, and calendered weaving Fabric. [0003] However, high-density woven fabrics, surface coatings and calendered woven fabrics generally have low softness (hard hand), ...
