Description

  The present invention relates to sports tights. More preferably, the present invention relates to sports tights such as marathons, jogging, and walks.

  Sports tights such as marathons can be used to apply pressure power to necessary muscles such as the buttocks, thighs, knees, and calves, control muscle vibration, or tighten the waist to control posture. Various compression types are known. Conventionally, sports tights use elastic knitted fabric containing elastic yarn such as polyurethane yarn, place elastic knitted fabric with high elasticity at necessary places, and elastic knitted fabric with low elasticity at other places (For example, Patent Documents 1 and 2). Further, Patent Documents 3 to 4 propose that a resin or adhesive is applied between the outer material and the lining material to obtain a stretchable part fabric.

  However, the tights proposed in Patent Documents 1 and 2 have a large mass (unit weight) per unit area of knitting, and it has been difficult to obtain light tights. Further, the clothes proposed in Patent Documents 3 to 4 have not been devised to lighten the basis weight, and further improvement has been demanded.

  In order to solve the above-described conventional problems, the present invention provides sports tights that reduce the overall mass, reduce the burden on the wearer, and have high exercise functionality.

  The sports tights according to the present invention are sports tights composed of at least a first fabric and a second fabric, wherein an adhesive portion in which the two fabrics are laminated and integrated with an adhesive, and a non-adhesive portion are provided. In addition, the adhesive portion is configured by an island portion where the adhesive is independent, and stress at a predetermined elongation rate is partially different.

  The sports tights of the present invention include an adhesive portion in which both the first fabric and the second fabric are laminated and integrated with an adhesive, and a non-adhesive portion, and the adhesive portion is an island with an independent adhesive. Since the stress at a predetermined elongation rate is partially different, the overall mass is reduced, the burden on the wearer is reduced, and sports tights with high exercise functionality can be provided.

1A is a front view of sports tights (long tights) according to an embodiment of the present invention, FIG. 1B is a rear view thereof, and FIG. 1C is a right side view thereof. 2A is a schematic explanatory view of a honeycomb-shaped adhesive portion in sports tights according to an embodiment of the present invention, FIG. 2B is a schematic explanatory view of the same dot-shaped adhesive portion (high density), and FIG. 2C is the same dot-shaped adhesive portion. It is a typical explanatory view of (low density). FIG. 3A is a load-elongation rate hysteresis curve of the power part in the body length direction in the sports tights of one embodiment of the present invention, and FIG. 3B is a load-elongation rate hysteresis curve of the body material in the body length direction. 4A is a load-elongation rate hysteresis curve of the power part in the body circumference direction in the sports tights of one embodiment of the present invention, and FIG. 4B is a load-elongation rate hysteresis curve of the body material part in the body circumference direction.

  The present invention is a sports tight that includes at least a first fabric and a second fabric. The first fabric and the second fabric can be used in a so-called reversible manner, when either one becomes the outer material or the other becomes the outer material. In addition to the first fabric and the second fabric, for example, a rubber belt or a waist strap at the waist may be included. The first fabric and the second fabric are preferably knitted. If knitted, the basis weight is light, the stretchability can be kept high, and the motor function is not hindered.

The first fabric and the second fabric are knitted fabrics, and the weight per unit area is 90 to 200 g / m ² , preferably 100 to 160 g / m ² , and more preferably 110 to 130 g / m ² . If the basis weight is in the above range, the entire mass can be reduced and the burden on the wearer can be reduced.

  The first fabric and the second fabric include an adhesive portion laminated and integrated with an adhesive, and a non-adhesive portion where the two fabrics are separated. The bonded portion is strongly stretchable, and the non-bonded portion is weakly stretchable. Moreover, the adhesion part is comprised by the island part from which the adhesion part became independent. This keeps the breathability high. Furthermore, the adhesive portion partially differs in stress at a predetermined elongation rate. For example, in areas where you want to exert strong pressure resistance, increase the adhesive area ratio to increase the stress at a predetermined elongation rate, and in areas where you want weak pressure resistance, decrease the stress at the predetermined elongation ratio, so that pressure resistance is not required. Is a non-adhesive part. Here, the predetermined elongation rate refers to one point in the range of, for example, an elongation rate of 20 to 100%. For example, it refers to any point of 20%, 40%, 60%, 80%, 100% elongation.

  The bonding portion is preferably in the form of dots and / or honeycombs. Thereby, it is possible to increase the stress at a predetermined elongation rate of the fabric while maintaining high air permeability, or to control the stress at several stages.

  The bonding area ratio of the bonding portion preferably includes a portion of 55% or more and less than 65%, a portion of 35% or more and less than 45%, and a portion of less than 35%. Thereby, the thing from the high to the low thing in the predetermined elongation rate of lamination | stacking integrated fabric can be obtained. Specifically, a portion having a high adhesion area ratio has high stress, and a portion having a low adhesion area ratio has low stress.

  It is preferable that the non-bonding portions of the first fabric and the second fabric exist at least in the heel portion and the knee back portion. This portion is a region where no pressure is required.

The bonded portion preferably has a load of 14.7 N and an elongation of 40 to 80%. The elongation rate is sufficient as a function for supporting muscles. Moreover, it is preferable that both the bonding part and the non-bonding part have a higher elongation rate in the body length direction when a load of 14.7 N is applied than in the peripheral direction. This does not hinder the motor functionality of the human body, which has a relatively high elongation rate in the body length direction. Specifically, the following ranges are preferable.
(1) Bonded portion: The elongation rate in the body length direction is 1.1 to 2 times, preferably 1.2 to 1.8 times the elongation rate in the circumferential direction. (2) Non-bonded portion: The elongation rate in the body length direction is the circumferential direction. 1.1 to 3 times, preferably 1.5 to 2.5 times the elongation ratio

The sports tights of the present invention preferably have a breathability of 10 to 70 cm ³ / cm ² · s in any place in a JIS L 1096 A method (Fragile method) test. Further preferable air permeability is 40 to 70 cm ³ / cm ² · s. If the breathability is in the above range, it can be worn cool, easy to dry even with sweat, and comfortable to wear.

  The sports tights preferably have a mass per long tights of 80 to 165 g, more preferably 100 to 160 g. If it is the said range, it is still lighter, can reduce a burden of a wearer, and can provide the sports tights with high exercise functionality. Especially for marathon runners, even lighter 1g is more advantageous, and light tights are preferred.

  It is preferable that the first fabric and the second fabric can be both front and back and can be reversibly worn. If it does in this way, while being able to select the cloth surface according to liking, a wearing period can also be lengthened and it is convenient for a runner.

  The skirt of the sports tights may be cut off. A quick cut is the state of being cut. The reason why it can be cut is that the bonded portion in which both fabrics are laminated and integrated with an adhesive is composed of independent island portions, and fraying stops by the island portions. If it is a fine island, fraying does not occur at all. By cutting quickly, the mass of the tights can be reduced and the manufacturing cost can be reduced.

  The fabric is preferably a knitted fabric. Examples include round, horizontal, vertical (including tricot, russell), pile, etc., flat, tense, rib, smooth (double-sided), rubber, pearl, and denby structures. , Cord tissue, atlas tissue, chain tissue, insertion tissue, etc. The fabric is made into tights by sewing. The fiber used for the knitted fabric is preferably a polyethylene terephthalate (polyester) filament yarn, the same spun yarn, a nylon filament yarn, the same spun yarn, a polyurethane filament yarn or a combination thereof.

  The adhesive for laminating and integrating the first fabric and the second fabric is preferably an elastic resin, and specifically, polyurethane, silicone rubber, silicone gel, and the like are preferable. These resins can be laminated and integrated by applying them to one of the two fabrics in the form of a liquid resin by printing, pasting the other fabric in a wet state, and curing by heating.

  Hereinafter, it demonstrates more concretely using an Example. In addition, this invention is limited to a following example and is not interpreted.

Example 1
(1) First fabric Nylon multifilament yarn (single fiber fineness: 0.97 decitex, total fineness: 33 decitex, number of components 34, raw yarn) 77% by mass, polyurethane filament yarn (single fiber fineness: 22 decitex) 23% by mass A smooth knitted fabric was prepared using a 54 gauge circular knitting machine. The basis weight was 122 g / m ² , and the air permeability was 62.4 cm ³ / cm ² · s. The knitting was dyed black.
(2) Second fabric Nylon multifilament yarn (single fiber fineness: 0.97 decitex, total fineness: 33 decitex, number of components 34, raw yarn) 77% by mass, polyurethane filament yarn (single fiber fineness: 22 decitex) 23% by mass A smooth knitted fabric was prepared using a 54 gauge circular knitting machine. The basis weight was 122 g / m ² , and the air permeability was 69.8 cm ³ / cm ² · s. This knitting was dyed blue.
(3) Stacking and integrating the first and second fabrics A polyurethane liquid resin (viscosity 55,000 to 65,000 cps at 25 ° C.) is applied to the second fabric by printing, and is wet. In the state, the first dough was pasted and then heat-cured. The adhesion part was a dot-like thing and a honeycomb-like thing.
(A) Honeycomb bonded portion The bonding area ratio of the bonded portion was about 60% (60% dots).
(B) Dot-shaped high-density adhesive part The adhesive area ratio of the adhesive part was about 40% (40% dots).
(C) Dot-shaped low-density adhesion part The adhesion area ratio of the adhesion part was about 30% (30% dots).
The elongation and stress of this laminated fabric are as shown in Tables 1 and 2, and the load-elongation measurement data are as shown in Table 3.

  FIG. 3A shows a load-elongation rate hysteresis curve in the body length direction of the power part in the sports tights of one embodiment of the present invention, FIG. 3B shows a load-elongation rate hysteresis curve in the body length direction of the body part, and FIG. FIG. 4B is a body circumference direction load-elongation rate hysteresis curve of the body portion. As a result, the bonded portion has a load of 14.7 N and an elongation rate of 40 to 80%, and the stretch rate in the body circumferential direction is lower than the body length direction. It can be seen that the elongation rate in the body circumferential direction is lower than that in the body length direction.

(4) Sewing Tights Using the laminated fabric obtained as described above, long type tights shown in FIGS. 1A to 1C were sewn. The adhesion area ratio of the lower abdomen 6 was about 0.8%. The mass per piece of the long tights was 155 g. This is a light weight that is superior to conventional 185g or more long product tights.

(5) Wear test of tights The wear test of the obtained tights was conducted. For comparison, a conventional commercially available long tights 185 g (single layer knitted fabric) was used. As a result, the pressure feeling of this example product was the same as that of the conventional product, but because it is lightweight and highly breathable, the overall wear feeling is much better than the conventional product. It has been confirmed that this is a sports tight with high exercise functionality. Further, in the tights of this example, the first fabric and the second fabric both became the outer material and the lining material, and could be reversibly worn.

  The sports tights of the present invention are suitable not only as tights for marathons, jogging, trail running, walking, mountain climbing, but also for various sports. It is particularly suitable for competition tights such as marathons.
