FIG.

The present inventors have intensively studied in order to achieve both the stability of the underwater posture and the effect of supporting the movement of the hamstring by the swimsuit. First, the elongation of the skin on the back of the lower body during crawl, butterfly, backstroke and breaststroke was analyzed using the technique described in Japanese Patent No. 3831348. The result is shown in FIG. (A) is a crawl, (b) is a butterfly, (c) is a backstroke, and (d) is a case of a breaststroke. In FIG. 9, reference numeral 200 indicates the degree of skin elongation, and the degree of skin elongation increases as it goes from I to II. As can be seen from FIG. 9, the skin stretched in the region covering the proximal third of the hamstrings from the top of the buttocks during various swimming. In the swimsuit according to the present invention, two or more belt-like tightening portions cross each other along the body length direction (also referred to as the height direction) from the left and right buttocks to the thigh, and the two As shown in FIG. 10, the intersection of the band-like tightening portion (hereinafter also simply referred to as “intersection”) extends from the top of the buttocks where the skin stretches during swimming to the proximal 1 / By arranging to be located in the area up to 3, it is possible to stabilize the underwater posture and support the movement of the hamstrings. For example, the hip extensors, including the greater ankle, middle gluteus, gluteal and hamstrings, and semi-tendonoid, semi-aponeurotic, mid-gluteal (outside), and gluteal (outside) And the muscle burden of the hip internal rotator muscle group including the thigh fascia latae muscle is reduced. Hamstrings is a combination of the biceps femoris, the semi-membranous muscle, and the semi-tendon-like muscle on the back of the thigh (back of the lower limbs). In this specification, “proximal ３ of hamstrings” means that the distance from the proximal end is 100% when the length in the height direction from the proximal end to the distal end of the hamstrings is 100%. This refers to the part that is% / 3. Further, the “top of the buttocks” refers to a part having a distance of 100% / 2 from the lower end of the gluteal muscle when the length in the height direction from the upper end to the lower end of the gluteal muscle is 100%.

In the present invention, “stretchable fabric” means that the elongation rate in the body length direction of the fabric exceeds 0%. In the present invention, the elongation rate of the fabric is measured based on JIS L 1096 8.14.1 A method (load 17.6 N, tensile speed 200 mm / min).

The tightening portion has a tightening force, that is, a tensile elastic modulus in the body length direction, higher than other portions. In the swimsuit of the present invention, the tensile elastic modulus of the tightening portion is higher than the tensile elastic modulus of the stretchable fabric constituting the main body of the swimsuit, and the tensile elastic modulus at the intersection of the tightening portions is the highest. In the present invention, the tensile elastic modulus is JIS L 1096 8.14. Based on the A method, specifically, the fabric piece is fixed to a tensile testing machine so that the width is 5 cm and the length is 10 cm, and the tensile elastic modulus (N / mm ² ) is determined from the inclination of the stress at 5% elongation. Ask. The length of the dough piece means the size in the direction coinciding with the measurement direction. For example, when measuring the tensile modulus in the body length direction, the length of the fabric piece means the size in the body length direction of the fabric piece, and when measuring the tensile modulus in the width direction, the length of the fabric piece is the fabric length. It means the size in the width direction of one piece.

The stretchable fabric is not particularly limited, but the tensile modulus in the body length direction is preferably 140 × 10 ⁻⁵ N / mm ² or more and 200 × 10 ⁻⁵ N / mm ² or less, more preferably 150 × 10. ⁻⁵ N / mm ² or more and 190 × 10 ⁻⁵ N / mm ² or less, and more preferably 160 × 10 ⁻⁵ N / mm ² or more and 180 × 10 ⁻⁵ N / mm ² or less. If the tensile elastic modulus of the stretchable fabric is within the above-described range, the wearability of the swimsuit will be good and the fit will be improved.

The stretch fabric is not particularly limited, and stretch fabrics that are usually used for swimwear can be used. For example, a one-way or two-way woven or knitted fabric including an elastic yarn is preferable. The elastic yarn is preferably at least one selected from a polyurethane elastic yarn and a polyester elastic yarn. This is because it is highly stretchable and suitable for sports clothing. The elastic yarn may be used as a bare yarn, in alignment with a non-elastic yarn (rigid yarn), or may be used as a covered yarn whose surface is coated with polyester fiber or nylon fiber. . The stretchable fabric may be a double fabric.

The stretch fabric preferably has a basis weight in the range of 50 g / m ^{2 to} 400 g / m ² , more preferably in the range of 80 g / m ^{2 to} 300 g / m ² , and even more preferably 100 g / m 2. in the range of ² or more 200 g / m ² or less. Within this range, problems such as sheer do not occur, it is suitable for aesthetics, and it is excellent in wearability without feeling of weight.

The tightening portion preferably has a tensile modulus in the body length direction of 160 × 10 ⁻⁵ N / mm ² or more and 220 × 10 ⁻⁵ N / mm ² or less. More preferably, it is 165 × 10 ⁻⁵ N / mm ² or more and 200 × 10 ⁻⁵ N / mm ² or less, and further preferably 170 × 10 ⁻⁵ N / mm ² or more and 190 × 10 ⁻⁵ N / mm ² or less. is there. The intersection of the tightening portions preferably has a tensile elastic modulus in the body length direction of 220 × 10 ⁻⁵ N / mm ² or more and 420 × 10 ⁻⁵ N / mm ² or less. More preferably 240 × 10 ^-5 N / mm ² or more 400 × 10 ^-5 N / mm ² or less, more ^{preferably, 260 × 10 -5 N / mm} 2 or more 380 × 10 ^-5 N / mm ² or less It is. When the tensile elastic modulus in the body length direction of the tightening portion and the intersection thereof is within the above-described range, it is easy to wear a swimsuit and the effect of supporting the movement of the hamstring, for example, a kick or the like is enhanced. The tensile elastic modulus in the body length direction of the tightening portion is obtained by cutting a piece of cloth (width 5 cm, length 15 cm) including a single band-shaped tightening portion from a place where the tightening portion other than the intersection is arranged in the swimsuit. , Measured as a measurement sample. For example, in FIG. 1, a piece of fabric indicated by 300 is cut and used to measure the tensile elastic modulus of the tightening portion. The tensile elastic modulus in the body length direction of the intersection of the tightening portions is determined by cutting a piece of cloth (width 5 cm, length 15 cm) including the intersection of the tightening portions from the place where the intersection of the tightening portions is arranged in the swimsuit. , Measured as a measurement sample. For example, in FIG. 1, a portion of the fabric indicated by 400 is cut and used to measure the tensile elastic modulus at the intersection of the tightening portions.

The tightening portion is arranged in a belt shape along the body length direction from the right and left buttocks to the thigh. Two or more of the tightening portions are hung from the left and right buttocks to the thigh, and the intersection is located in the region from the top of the buttocks to the proximal third of the hamstrings, for example, There are no particular limitations as long as two, three, four, etc. are arranged. From the viewpoint of wearing feeling, it is preferable that two of the tightening portions are arranged from the left and right buttocks to the thigh.

The underwater posture can be stabilized more effectively. At least one of the tightening portions is preferably disposed so as to pass around the sacrum from the viewpoint of more effectively stabilizing the underwater posture. From the viewpoint of stabilizing the underwater posture more effectively and supporting the movement of the hamstrings, the intersection of the tightening portions is preferably located in a region covering a part of the hamstrings, and the biceps femoris and / or half More preferably, it is located in a region covering a part of the tendon-like muscle.

The tightening portion is not particularly limited. For example, after attaching a tension tape (also referred to as a tension band) to the stretchable fabric constituting the swimsuit main body so that the longitudinal direction of the tension tape is along the body length direction, From above, a tape-like stretchable fabric having a width wider than that of the tension tape is provided so as to cover the tension tape and so that the longitudinal direction of the tape-like stretchable fabric is along the body length direction. Can do. From the viewpoint of reducing shape resistance, the tension tape and the tape-like stretchable fabric are preferably located on the back side (body surface side) of the swimsuit. By sticking the tape-like stretchable fabric on the tension tape, it is possible to improve the durability of the tightening portion and to prevent the tension tape from being detached from the swimsuit body. For example, from the viewpoint of reducing surface friction, the tension tape and the tape-like stretchable fabric preferably have a width of 5 mm to 30 mm, and more preferably 10 mm to 20 mm. The tension tape and the tape-like stretchable fabric are preferably bonded together by a hot melt adhesive.
