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

[0090] Core: Polyurethane (denier: 55decitex, "Lycra" 254B manufactured by Toray Opelontex Co., Ltd.)

[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 the double weft weave portion 3 shown alternately repeat the stretch fabric 1 for weaving. Using a rapier loom, make plain weaving part 2 longitudinal density: 195 threads / 2.54cm, transver...

Embodiment 2

[0098] Using the yarn of Example 1 above, a stretchable fabric was 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 double weft 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

This stretch woven fabric (1) includes elastic yarns, the elastic yarns being arranged in the warp (4) and the weft (5, 6a, 6b). The stretch woven fabric has two-way stretch properties, and includes alternately repeating plain weave sections (2) and double weave sections (3). The elastic yarns are more numerous in the double weave sections (3) than in the plain weave sections (2) and provide reinforcement, and therefore the stretch properties are higher, and wear is easier. The plain weave sections are sunken portions and the double weave sections are raised portions, producing overall a stripe-shaped structure in which sunken and raised portions are arrayed in a single direction, whereby, in the case of swimwear for example, surface friction drag with respect to water flow can be reduced through use while the stripe shapes are aligned with the body height direction. In so doing, there are provided a stretch woven fabric that has high stretch properties, ease of wear, and low surface friction drag, and sportswear or swimwear that includes the fabric.

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...
