Embodiment 1

[0080] 1. The use of silk thread

[0081] (1) Warp

[0082] Core: Polyurethane (denier: 78decitex, "Lycra" 176B manufactured by Toray Opelontex Co., Ltd.

[0083] Coated silk: Nylon raw silk (33decitex fineness, 10 filaments)

[0084] Single core yarn (SCY)

[0085] (2) Weft

[0086] Core: Polyurethane (denier: 44decitex, "Lycra" 254B manufactured by Toray Opelontex Co., Ltd.)

[0087] Coated silk: Nylon raw silk (33decitex fineness, 10 filaments)

[0088] Single core yarn (SCY)

[0089] (3) Weft top line

[0091] Coated silk: Nylon raw silk (33decitex fineness, 10 filaments)

[0092] Single core yarn (SCY)

[0093] 2. Fabric

[0094] right figure 1 The plain weave portion 2 and weft double weave portion 3 shown alternately repeat the stretch fabric 1 for weaving. Using a rapier loom, the longitudinal density of plain weave part 2: 195 threads / 2.54cm, the transvers...

Embodiment 2

[0098] Using the above-mentioned yarn of Example 1, stretchable fabrics were produced in the same manner as in Example 1, except that the width of the plain weave portion 2 was 0.5 mm and the width of the weft double weave portion 3 was 0.5 mm. The elongation of the fabric was 57.1% in the warp direction and 41.6% in the weft direction, and the stress at 30% elongation was 1.56 N / cm in the warp direction and 1.40 N / cm in the weft direction. The frictional resistance coefficient and water entry time of the fabric are shown in Table 1.

Embodiment 3

[0100] Using the yarn of the above-mentioned Example 1, the elastic fabric was subjected to smoothing processing on the surface of the fabric in the same manner as in Example 1.

[0101] Smoothing is a process of heating and pressing between a pair of rolls. The roll temperature is 220°C, the linear pressure is 5500kgf, and the roll speed is about 6-10m / min. The elongation of the fabric was 54.2% in the warp direction and 43.0% in the weft direction, and the stress at 30% elongation was 1.68 N / cm in the warp direction and 1.35 N / cm in the weft direction. The frictional resistance coefficient and water entry time of the fabric are shown in Table 1.

Abstract

The stretchable fabric (1) of the present invention contains elastic yarns arranged on warp threads (4) and weft threads (5, 6a, 6b), the stretchable fabric has stretchability in two directions, and the plain weave part (2 ) and the double weave part (3) are alternately repeated. Since the double weave part (3) is reinforced by arranging more elastic threads than the plain weave part (2), stretchability is improved and it is easy to wear. In addition, since the plain weave part is a concave part, the double weave part is a convex part, and the concave and convex parts are arranged in one direction as a whole to form a striped structure, so when making, for example, a swimsuit, when the When the stripe shape is used on the position, the surface frictional resistance with the water flow can be reduced. Thereby, a stretchable fabric having high stretchability, easy to wear, and low surface frictional resistance, and sportswear and swimwear including the stretchable fabric are provided.

Description

technical field [0001] The present invention relates to a stretchable fabric with high stretchability and sportswear and swimwear containing the stretchable fabric. Background technique [0002] For sportswear or swimwear, materials with good stretchability are preferable. In addition, one of the required functions of a swimsuit or a cap is how to reduce the surface frictional resistance of the swimsuit in water generated during swimming competitions. Various stretch fabrics have been proposed, and Patent Document 1 proposes a stretch fabric in which regions with different stresses are formed using weft yarns with different stresses. Patent Documents 2 to 3 propose stretch fabrics having a specific elongation. As a technique for reducing the surface frictional resistance of a swimsuit, for example, Patent Document 4 proposes a swimsuit in which hydrophobic portions and non-hydrophobic portions are arranged in stripes in the body length direction. Patent Document 5 propose...
