Description

  The present invention relates to sports clothing. More specifically, the present invention relates to a sports garment that is thin, lightweight, and has excellent breathability, misalignment prevention, coolness, and stretchability.

Traditionally, knitted fabrics are often used in sports clothing, but in general, sports clothing for knitted fabrics is a lightweight fabric with a low weight and a poor air permeability, and sports with intense exercise (for example, , Soccer, etc.). In recent years, knitted fabrics have been improved to have a mesh structure to improve air permeability and woven fabrics have improved stretch properties. However, they are thin, lightweight, and have excellent coolness and stretchability. There was no sports clothing and its appearance was desired.
On the other hand, as a clothing with high coolness, a woven fabric (hereinafter referred to as an entangled woven fabric) having an entangled woven structure has been used in Japanese clothes.

Patent Document 1 describes a clothing outer garment that specifies the amount of woven fabric and has high air permeability and difficulty of see-through at the same time by using a specific woven fabric structure and a specific thread use, and is less likely to cause misalignment. .
Patent Document 2 discloses an anti-slip body characterized in that a normal warp and another warp having an anti-slip effect are woven in a woven structure, and the warp having an anti-slip effect is exposed on the surface. Has been. As a warp having an anti-slip effect, an anti-slip body using elastic yarn and woven in an entangled weave is described.

  Although the above-described Japanese clothes and the outer clothing described in Patent Document 1 are rich in coolness, they are poor in stretchability and unsuitable for sports clothing that requires exercise tracking, high breathability, and lightness. Some of the anti-slip bodies described in Patent Document 2 have elasticity in the warp direction, but did not satisfy the performance required for clothing. As described above, the functions required for sports clothing (thin and light, with excellent ventilation and cooling, excellent stretchability) and basic fabric performance (slip resistance, tearing strength, anti-snugging properties, etc.) So far, sports clothing that satisfies the requirements at the same time has not been obtained.

  The purpose of the present invention is to provide the functions required for sports apparel (thin, light, breathable / cool, excellent in stretch properties) and basic fabric performance (slip resistance, tear strength, anti-snugging properties, etc.) It is to provide sports clothing that satisfies (good) at the same time.

In order to solve the above-mentioned problems, the present inventors have found that the object of the present invention can be achieved by using a woven fabric with a woven structure and specifying fabric characteristics for sports clothing. It came to complete.
That is, the present invention is as follows.

1. A sports garment using a fabric having a warp and / or weft stretch ratio of 10% or more and a warp and weft tear strength of 7N or more, and the total cover factor of the fabric is 1200 to 1800. Sports clothing characterized in that the woven tissue is entangled.

Hereinafter, the present invention will be described in detail.
The sports apparel referred to in the present invention includes shirts, pants, and shorts worn as outerwear or underwear for various sports, and may be used for competition or training. Examples include soccer shirts, golf shirts, tennis shirts, basketball shirts, table tennis shirts, badminton shirts, running shirts, soccer pants, tennis pants, basketball pants, table tennis pants, badminton pants, running pants, various sports undershirts, various types. Examples include sports innerwear.
The tangle weave in the present invention is a fabric structure well known in the Japanese clothing industry, for example, as shown in pages 89 to 102 of Textile Engineering 2 “Fabric” published by Jikkyo Publishing Co., Ltd. is there.

FIG. 1 is a diagram showing the most basic woven fabric texture. This is a woven fabric in which a ground warp a and an entangled warp b are arranged by changing the position of each weft c and a tangent d is formed between the weft and the weft.
FIG. 2 is a woven structure diagram of the 3.1. This is a woven fabric in which ground warp a and entangled warp b are organized by changing the positions of every one or three wefts c, and entangled d is formed between the weft and the weft.
FIG. 5 is a three-ply fabric structure diagram. This is a woven fabric in which two ground warps a and entangled warps b are formed by changing the positions of every two wefts c, and an entangled line d is formed between the wefts and the wefts.

  Examples of the texture of the woven fabric in the present invention include cocoons, cocoons, irregular cocoons that combine cocoons and cocoons, and the like. There is. In the present invention, a combination of these can be used according to the purpose. Examples of a preferable organization for sports clothing include two-string kites, three-string kites, 3 · 1 anomalies, and 5 · 1 anomalies.

It is important that the woven fabric used in the present invention has a total cover factor (TC) of 1200 to 1800, preferably 1300 to 1700, more preferably 1400 to 1600. If the total cover factor is less than 1200, it is difficult to suppress misalignment. When the total cover factor exceeds 1800, when used in clothing, the air permeability becomes poor and the mass increases. Therefore, the suitability as sports clothing is reduced.
In the present invention, the total cover factor (TC) of the fabric is calculated by the following equation.
TC = [fineness of warp (dtex)] ^0.5 × warp density (main / 2.54 cm) + [fineness of weft (dtex)] ^0.5 × weft density (main / 2.54 cm)

The tear strength in the warp direction and the weft direction of the fabric used in the present invention is 7N or more, preferably 10N or more. If the tear strength is less than 7N, the fabric performance for use as sports clothing is not satisfied.

When the breaking strength of the yarn constituting the weft is 75 cN or more, sports clothing having a sufficient tear strength can be obtained.
The woven fabric used in the present invention has a warp and / or weft stretch ratio of 10% or more, preferably 15 to 75%, more preferably 20 to 70%.

The reason why the misalignment prevention property is improved by using the coated elastic yarn and / or the crimped yarn of polytrimethylene terephthalate fiber for the woven fabric is not clear, but the frictional force of these yarn and the woven fabric are formed. It is presumed that the misalignment is suppressed by the combination of the warp and the weft tangling force.

The measurement methods and evaluation methods used in the present invention are as follows.
(1) Intrinsic viscosity Intrinsic viscosity [η] (dl / g) is a value determined based on the definition of the following equation.

In the formula, ηr is the viscosity of a diluted solution of polytrimethylene terephthalate fiber or polyethylene terephthalate fiber dissolved in an o-chlorophenol solvent having a purity of 98% or more, divided by the viscosity of the solvent measured at the same temperature. Which is defined as relative viscosity. C is the polymer concentration expressed in g / 100 ml.
In the case of a composite fiber using polymers having different intrinsic viscosities, it is difficult to measure the intrinsic viscosity of each polymer constituting the composite fiber, so two types of polymers are used under the same conditions as the spinning conditions of the composite fiber. The intrinsic viscosity measured using each of the obtained yarns is regarded as the intrinsic viscosity of the polymer constituting the composite fiber.

(2) Initial tensile resistance In accordance with the chemical fiber filament yarn test method (initial tensile resistance test method) of JIS-L-1013, a tensile test is performed by applying an initial load of 0.0882 cN / dtex per unit fineness of the sample. The initial tensile resistance (cN / dtex) is calculated from the obtained load-elongation curve. Ten samples are arbitrarily collected and measured, and the average value is obtained.
(3) Tensile strength: Measured according to the chemical fiber filament yarn test method of JIS-L-1013 (7.5 tensile strength measurement method).

The stretch elongation rate and stretch elastic modulus of the untreated yarn are measured after leaving the sample unwound from the winding package in an environment of a temperature of 20 ± 2 ° C. and a relative humidity of 65 ± 2% for 24 hours. For the stretchable elongation rate and the stretchable elastic modulus after the hot water treatment, a sample that is naturally dried for 24 hours without load after being immersed in hot water at 95 ° C. for 15 minutes without load is used.

(5) Opening ratio of the fabric Using a magnifying device (Scopeman (registered trademark) 503: manufactured by MORITEX Co., Ltd.), five or more magnified photographs were taken from the sample. Measure the value of (part not to be treated) / sample area] and average the value to determine the open area ratio of the fabric.
(6) Weight per unit area A sample is cut into a 10 cm × 10 cm square, its mass is measured, and it is determined from a value multiplied by 100.

(7) Air permeability Measured according to JIS-L-1096-8.27.2A method (Fragile type method).
(8) Stretch rate of fabric, stretch recovery rate The stretch rate is the value of the stretch rate measured by the stretch B method (constant load method) of JIS-L-1096-8.13.2 stretch fabric.
The stretch recovery rate is measured according to JIS-L-1096-8.14.2.

(9) Surface smoothness Five experienced persons who have been engaged in the textile work for 5 years or more served as monitors, performed sensory evaluation, and performed the following four-stage determination.
A: Extremely smooth surface O: Almost smooth surface Δ: Surface slightly inferior in smoothness X: Wrinkles etc. are generated and inferior in smoothness

(10) Anti-slip property Five experienced persons who have been engaged in the textile work for 5 years or more became monitors, and sensory evaluation was performed, and the following four steps were determined.
◎: Extremely superior anti-skid property ○: Almost excellent anti-skid property △: Slightly inferior anti-skid property ×: Inferior anti-skid property

4 points: very good coolability 3 points: moderately good coolness 2 points: slightly inferior in coolness 1 point: clearly inferior in coolness

(12) Sliding resistance Measured with a tensile load of 117.8 N according to JIS-L-1096B. It shows that sliding resistance is so favorable that a numerical value is large.
(13) Tear strength Measured by the Benjuram method according to JIS-L-1096D.
(14) Snugging Measured by JIS-L-1058D-3 method.
(15) Dimensional change rate Measured by the JIS-L-1042H-3 method.
