JP7072738B2 - Bottom clothing - Google Patents

Description

The present invention relates to bottom clothing.

Conventionally, various types of girdles, shorts, shorts, tights, spats, etc. have been studied for the purpose of improving the support and shape retention of the buttocks muscles. For example, a girdle has been proposed in which a member having a stronger tightening force than the main body is partially arranged on the girdle main body to enhance the muscle support effect (see Patent Document 1 below). Similarly, many sports tights and compression wear have been proposed.
In addition, if you cannot walk properly like O-legs and X-legs in your daily life, the knee joints will be strained, leading to muscle weakness and knee pain.

Many studies have been made on clothing aimed at correcting such O-legs or X-legs. For example, by having a garment body and a band-shaped lateral knee support member, and forming the lateral knee support member with a low elastic material having a lower elongation rate in the height direction than the elastic material constituting the garment main body, an O-leg or an O-leg can be formed. Clothing that corrects the X-leg and reduces knee pain has been proposed (see Patent Document 2 below).

However, no studies have been conducted on bottom clothing that does not impede ease of movement during operation and has a large turning effect on the knee.

In the case of filament yarn, the fineness of the cellulose fiber used is preferably 30 dtex to 200 dtex, more preferably 30 dtex to 170 dtex, and further preferably 30 dtex to 120 dtex. Further, in the case of the spun yarn, the spun yarns of No. 60 to No. 30 are preferable, and No. 50 to No. 40 are more preferable. By mixing cellulose fibers, it is possible to obtain bottom clothing having excellent hygroscopicity, excellent antistatic properties, and excellent bending softness due to its hygroscopicity.

In the bottom garment of the present embodiment, elastic threads are arranged at least in a part of the body cloth constituting the bottom garment.
The elastic yarn partially arranged on the body cloth of the bottom garment of the present embodiment refers to a fiber having a breaking elongation of 100% or more. The polymer of the elastic yarn and the spinning method are not particularly limited, and examples thereof include polyurethane elastic yarn (also referred to as spandex or spandex fiber), polyether ester elastic yarn, polyamide elastic yarn, and polyolefin elastic yarn. For example, polyurethane elastic yarn may be used. , Dry-spun or melt-spun can be used. Further, these elastic yarns may be covered with non-elastic yarns in a covering state. Further, so-called rubber threads, which are in the form of threads made of natural rubber, synthetic rubber, and semi-synthetic rubber, can be used, but polyurethane elastic threads, which are excellent in elasticity and are generally widely used, are preferable. Among them, the diol component constituting the polyurethane polymer preferably has a side chain, more preferably the side chain is a methyl group, and further preferably having two methyl groups on the same carbon.

The breaking elongation of the elastic yarn is preferably 400% to 1000% from the viewpoint of giving the fabric good elasticity. The elongation at break is a value measured by the method described in JIS L1013 8.5.1 Tensile strength and elongation.
It is preferable that the elastic yarn does not impair its elasticity at around 180 ° C., which is a normal treatment temperature in the presetting process during dyeing. In addition, elastic yarn having functionality such as high settability, deodorant property, antibacterial property, hygroscopic property, and water absorption to which a special polymer or powder is added can also be used. Regarding the fineness of the elastic yarn, it is possible to use a fiber of about 10 dtex to 700 dtex (decitex, hereinafter the same symbol is used), and when looping with the elastic yarn, it is preferable to use an elastic yarn of about 12 dtex to 250 dtex. When the elastic yarn is inserted and knitted using a Raschel knitting machine, it is preferable to use an elastic yarn of 70 dtex to 700 dtex.

A woven fabric or a knitted fabric is used as the body cloth mainly constituting the bottom garment of the present embodiment, and is appropriately selected depending on the item. Knitting is preferable from the viewpoint of elasticity.
In the case of warp knitting, a structure in which elastic yarn is inserted or looped by a Raschel knitting machine or a tricot knitting machine is preferably used. For Raschel's tissue, a tissue with thick spandex fibers inserted such as 6-course satin, 4-course satin, 6-course tulle, and triconette is preferably used, and a tissue with two spandex inserted and stretched vertically and horizontally is a point of wearing feeling. Especially preferable. For tricots, half tricots, double stitches, atlas structures and the like are preferable because they have good elasticity.
In the case of a circular knit, it is preferable that the elastic yarn is looped.
As the body cloth, a woven fabric woven with elastic fibers is also preferably used.
As the basis weight of the body weight, a fabric having a basis weight of 50 to 400 g / m ² is preferably used.

As a product for general consumers, the body dough of the present embodiment preferably has a stress at 50% elongation in the horizontal direction of 0.3N to 3N, more preferably 0.3N to 2.5N, and even more preferably. Is 0.5N to 1.5N. The tensile stress is measured by using a Tensilon tensile tester to stretch a 2.5 cm wide fabric gripped at a gripping interval of 10 cm at a tensile speed of 300 mm / min and read the stress with a stretch ratio of 50%. When the stress at the time of 50% extension of the body cloth in the horizontal direction is 3N or less, the tightening at the time of wearing is not too strong and it is comfortable. On the other hand, if the stress at the time of 50% extension of the body cloth in the horizontal direction is 0.3 N or more, the wearing feeling is enhanced and it becomes easy to suppress the vibration of the body during operation. Further, as a product for athletes having a large amount of muscle, the stress of the body cloth at the time of 50% elongation in the horizontal direction is preferably 0.3N to 5N, more preferably 0.3N to 4.5N. More preferably, it is 0.5N to 4.0N.
Further, the stress at the time of 50% elongation of the body cloth in the vertical direction is preferably 0.3N to 4N. When the stress at the time of 50% extension in the vertical direction is 4N or less, the movement followability at the time of movement such as sitting or crouching is enhanced. On the other hand, when it is 0.3N or more, the wearing feeling is enhanced and it becomes easy to suppress the vibration of the body during operation or the like. In the present specification, the "horizontal direction" refers to the peripheral direction of the bottom product (the direction around the human body when worn), and the "vertical direction" refers to the vertical direction of the bottom product (the direction of the human body height when worn). Point to.

When used for inners such as girdles and shorts, it is preferable that the hem on the leg side has a hem structure formed by pulling out threads and a free-cut structure that can be used without fraying or curling of threads on the cut surface. .. By using these, since it is not necessary to sew the end portion, it is possible to prevent the end portion from becoming thick and to prevent the end portion from hitting the skin and leaving a mark on the skin. In addition, the line does not echo on the outer and it is excellent in aesthetics. As the free-cut material, for example, a mixed material of polyurethane and inelastic fiber, which is easily heat-sealed, is preferably used, and nylon or polyester is preferably used as the inelastic yarn.

The bottom garment of the present embodiment is characterized by having a double structure in which the inner fabric is overlapped on the inside of the body fabric (on the human body side when worn).
As the inner fabric, a woven fabric or a knitted fabric is used and is appropriately selected depending on the product, but a knitted fabric is preferable from the viewpoint of elasticity. In the case of warp knitting, a structure in which elastic yarn is inserted or looped by a Raschel knitting machine or a tricot knitting machine is preferably used. For Raschel's tissue, a tissue with thick spandex fibers inserted, such as 6-course satin, 4-course satin, 6-course tulle, and triconette, is preferably used, and a tissue with two spandex inserted and stretched vertically and horizontally is worn. Especially preferable from the viewpoint of feeling. In the jacquard raschel, there may be a difference in the tensile stress of the dough within the inner dough panel. As the tricot structure, half tricot, double stitch, atlas structure and the like are preferable because they have good elasticity. In the case of a circular knit, it is preferable that the elastic yarn is looped. As the woven fabric, a woven fabric woven with elastic fibers is preferably used. As the basis weight of the inner dough, a dough having a basis weight of 50 to 400 g / m ² is preferably used.

In the inner fabric of the present embodiment, the area covered by the inner fabric is preferably 60% or less of the area of the buttocks from the viewpoint of efficiently exerting the external rotation force or the internal rotation force. As used herein, the term "buttocks" refers to the area from the left and right sides of the human body and the ridge plane (waist) to the gluteal sulcus. If the inner fabric is 60% or less of the area of the buttocks, the stretch balance of the inner fabric is likely to change when worn, and the force to pull the thighs outward or inward becomes stronger, which is effective, and is effective at 50% or less. It is more preferable to have it. In addition, if the area covering the buttocks is more than a certain area, the inner fabric does not bite into the body when it is stretched, and the pressure applied during stretching is low, so that it is comfortable to wear. For this reason, the inner fabric preferably covers at least 10% or more of the buttocks. When covering the upper part of the thigh, it is preferable to cover a portion within 10 cm from the gluteal sulcus toward the lower leg.

The width of the inner fabric in the vertical direction of the product is preferably 5 cm to 20 cm, more preferably 5 cm to 18 cm. If the width of the inner fabric in the vertical direction is 5 cm or more, there is a sufficient covering area for the body, the stretching force when the fabric is stretched is likely to be applied to the body, and the external rotation effect or the internal rotation effect is likely to be exhibited. .. On the other hand, if the width of the inner fabric in the vertical direction is 20 cm or less, the stretch balance of the inner fabric is likely to change when worn, and the force to pull the thighs outward or inward becomes stronger, resulting in an external rotation effect or an internal rotation effect. Is easy to demonstrate.

The inner cloth of the bottom garment of the present embodiment is arranged inside the body cloth, and is characterized in that at least a part thereof is not adhered to the body cloth. Here, "not adhered" means that the fabrics are not always in close contact with each other and fixed by means such as sewing or bonding, and the fabrics are floating.

At least a part of the inner fabric whose elongation stress is more than 1.6 times and 10 times or less of the body fabric is overlapped with the body fabric without adhering to the body fabric, and at least a part of the inner fabric is adhered. By not doing so, when worn or stationary, the stretch balance of the inner fabric changes from the front side to the buttocks side, so that a force that pulls the thigh part outward or inward is generated.

Further, when walking, the inner fabric shifts according to the movement, and the expansion balance of the inner fabric changes significantly from the front side to the buttocks side as compared with the resting state, so that a force for pulling the thigh portion further outward or inward is generated. Due to the effect of pulling the thigh, an external or internal rotational force is generated on the lower leg, and a force for opening or closing the leg is generated. It is thought that this action leads to an increase in stride length and walking speed. In addition, by applying an external rotation force to the X leg and an internal rotation force to the O leg, the position of the femur is corrected in the normal direction, and it becomes easier for the leg to come out when standing, such as walking. Furthermore, it is thought that it will lead to an increase in stride length and walking speed.

In particular, since at least a part of the inner fabric is not adhered to the body fabric, the effect of turning the leg can be obtained by constantly pulling the leg surface with the inner fabric independently (not following).

In the bottom garment of the present embodiment, when the stress at 80% elongation in the vertical direction of the inner fabric product is A and the stress at 80% elongation in the horizontal direction of the inner fabric product is B, it is 0. .1 ≦ A / B <1.0, preferably 0.1 ≦ A / B <0.7, more preferably 0.1 ≦ A / B <0.5, and 0. It is more preferable that 1 ≦ A / B <0.3.

In the bottom garment of the present embodiment, the inner fabric is layered on the inside of the body fabric, and the ratio of the 80% elongation stress in the product vertical direction and the horizontal direction in the inner fabric is within a predetermined range, specifically, in the inner fabric. By making the vertical direction easier to stretch than the horizontal direction, the inner fabric follows the stretching of the skin during movement, and it is easy to move because it does not hinder the movement, and it efficiently applies external or internal rotation force to the body. Therefore, the turning effect on the knee is large.
Therefore, a corrective effect on the O-leg and the X-leg can be expected, and the walking assist effect is excellent by wearing the bottom garment of the present invention.

In the bottom garment of the present embodiment, when the stress at the time of 50% elongation in the horizontal direction of the body cloth product is C and the stress at the time of 50% extension of the inner cloth in the horizontal direction is D, 1.6 <D. / C ≦ 10 is preferable, 1.6 <D / C ≦ 8.0 is more preferable, 1.6 <D / C ≦ 6.0 is more preferable, and 1.6 < It is even more preferable that D / C ≦ 4.0, and it is particularly preferable that 1.6 <D / C ≦ 3.0.

The ratio of the stress C when the inner fabric is stretched 50% in the horizontal direction and the stress D when the inner fabric is stretched 50% in the horizontal direction is within a predetermined range. Specifically, the inner fabric is stretched in the horizontal direction. By making it more difficult to stretch, the inner fabric can efficiently apply an external rotation force or an internal rotation force to the body by pulling the leg during operation, so that the turning effect on the knee becomes larger.
However, if the stress at the time of extension of the inner fabric in the horizontal direction is too large, the tightening at the time of wearing becomes strong and the comfort is lowered.

As described above, in the bottom garment of the present embodiment, the extension stress in the horizontal direction is large, that is, it is difficult to stretch, and the extension stress in the vertical direction is small, that is, it is easy to stretch in the inner fabric, so that the leg is pulled to rotate or externally rotate. It is possible to achieve both the effect of internal rotation and the ease of movement during operation.

The relationship between the elongation stress in the horizontal direction and the elongation stress in the vertical direction in the body fabric and the inner fabric is, for example, for the body fabric, the warp direction of the warp knitted fabric is used in the horizontal direction (reverse use). The fabric can be realized by using the warp direction of the warp knitted fabric in the vertical direction.

Examples of preferable arrangement of each member in the bottom garment of the present embodiment are shown in FIGS. 1 and 2.
In FIG. 1, the inner fabric is arranged so as to cover the lower part of the buttocks from the waist. In the arrangement of this fabric, the amount of elongation from the waist to the buttocks of the inner fabric when worn is larger than the amount of elongation of the fabric at the part corresponding to the lower part of the buttocks. By generating a force (external rotation force) that pulls the portion outward, the effect of externally rotating the leg can be obtained.
In FIG. 2, the inner fabric is arranged from the base of the thigh or the inguinal region to the upper part of the buttocks or the gluteal sulcus to the upper part of the thighs. In the arrangement of this fabric, the amount of elongation of the inner fabric corresponding to the front part is larger than the amount of elongation of the inner fabric corresponding to the back part when worn. By generating an inward pulling force (internal rotation force), the effect of inwardly rotating the leg can be obtained.

In the bottom garment of the present embodiment, the area ratio of the portion of the inner fabric that is not adhered to the body fabric is preferably 70% or more, more preferably 80% or more, and further, with respect to the total area of the inner fabric. It is preferably 90% or more. When the area ratio is 70% or more, the body cloth and the inner cloth tend to move differently, and the leg correction effect can be easily obtained.

Adhesion is preferably performed at several ends of the inner fabric, for example, the upper end, the lower end, the side edges (the left and right ends of the inner fabric, the adhesive with the crotch, the front panel (tummy holding panel or). The adhesive portion with the panel) is collectively referred to as a side end portion. See FIG. 1). Of the edges of the inner fabric, 20% to 70% are preferably not adhered, and the non-adhesive portion is preferably the lower end of the inner fabric. Further, when the ratio of the end portion which is not adhered to the body fabric of the inner fabric is 20% to 100% with respect to the total length of the lower end portion of the inner fabric, the extension balance of the inner fabric is extended from the front side to the buttocks side or the back portion. It is preferable because the thigh portion is likely to change and the force for pulling the thigh portion to the outside or the inside becomes strong. The bonded portion and the non-bonded portion may be continuous or discontinuous. A waist rubber may be installed on the waist portion.

When the tummy holding panel is installed on the front surface with a girdle or the like, it is preferable that the side edges of the inner fabric are adhered to the left and right parts of the panel. The width of the panel in the product vertical direction is preferably 5 cm to 20 cm, and it is preferable that the inner fabric is adhered to one side of the front panel, passes through the back center, and is adhered to the front panel on the other side.

In order to generate the above-mentioned external rotation force, 70% or more of the adhesive portion of the side end portion of the inner fabric is above the horizontal line passing through a point 5 cm above the crotch portion on the front surface of the bottom garment when placed flat. It is preferably located at. The crotch portion indicates an apex divided into two crotches in the lower part of the bottom shown in FIG. As shown in FIG. 1, the portion indicated by the thick solid line at both ends of the inner fabric is the adhesive portion of the side end portion, and 70% of this thick solid line is above the horizontal line passing through the point 5 cm above the crotch portion. If it is located, external rotation force is likely to occur.
Further, in order to generate an internal rotational force, 70% or more of the adhesive portion of the side end portion of the inner fabric is below the horizontal line passing through a point 5 cm above the crotch portion on the front surface of the bottom garment when placed flat. It is preferable that it is adhered to. As shown in FIG. 2, the part indicated by the thick solid line at both ends of the inner fabric is the adhesive part at the side end, and 70% of this thick solid line is more stock than the horizontal line passing through the point 5 cm above the crotch part. If it is located, internal rotational force is likely to occur.
If the end of the inner fabric is above the area 5 cm above the crotch, the stretch of the inner fabric on the front is smaller than on the back, and if it is on the bottom, the stretch of the inner fabric on the front is on the back. Since it is larger than that, external rotation force and internal rotation force are generated when worn, respectively.

Adhesion can be done by sewing, bonding, etc., but a method that does not impair the elongation of the fabric is preferable, two-needle stitching or staggered stitching is preferable for sewing, and bonding is performed with a width of 0.5 cm to 1.5 cm for bonding. It is preferable to do it. Adhesion by bonding is more preferable because the step in the bonded portion is eliminated as compared with the case of sewing. It is also preferable to use a free-cut material for the inner fabric because the step at the end is eliminated.

The pressure applied to the buttocks of the bottom garment of the present embodiment is preferably 5 hPa to 20 hPa, more preferably 8 hPa to 18 hPa. The pressure on the buttocks is the average of the pressure on the left and right at the tops of the left and right mountains (hip tops) at the position where the circumference of the buttocks is the largest. It is attached and measured with an air pack type pressure gauge. In addition, for L size bottom clothing, it is attached to an L size standard body type mannequin and measured. When the pressure applied to the buttocks is 5 hPa or more, the pressure is sufficiently large and the effect of suppressing shaking during operation is high, which is preferable. On the other hand, if the pressure on the buttocks is 20 hPa or less, the feeling of oppression can be reduced and the wearing comfort is enhanced.

It is preferable that the bottom clothing for athletes has a slightly stronger pressure from the viewpoint of supporting exercise performance, and the pressure on the buttocks is preferably 10 hPa to 20 hPa. In the case of bottom clothing for athletes, polyester fibers are desirable as the inelastic yarn used for the body fabric or the inner fabric from the viewpoint of sweat treatment.
The bottom clothing for the elderly is preferably worn with a slightly weaker pressure, and the pressure on the buttocks is preferably 5 hPa to 15 hPa. When the pressure on the buttocks is within the above range, the ease of wearing is also improved.
The inner fabric can also be layered on the legs of shorts and compression wear to prevent thigh sway and calf sway.

The cross-sectional shape of the filament yarn is not particularly limited, such as 〇, Δ, cross, W type, M type, C type, I type, dogbone type, and hollow fiber.
The form of the spun yarn may be either a single yarn or a blended yarn. The blended spinning method is not particularly limited, but a spun yarn obtained by an MVS method in which pilling is less likely to occur is preferable.
The inelastic yarn can be arbitrarily selected from bright yarn, semi-dull yarn, full dull yarn and the like.

Cellulose fibers may be used as a part of the inelastic yarn. Cellulose fibers are also not particularly limited, and for example, cupra, rayon, bamboo fibers, cotton, modal, and tencel can be used.
The cellulose fiber may be any of a raw yarn (unprocessed yarn), a false twisted yarn, a yarn-dyed yarn and the like in the form of a filament yarn, and may be the above-mentioned composite yarn. Further, the cellulose fiber may be in the form of a spun yarn, either alone or in a blended manner.

In the case of filament yarn, the fineness of the cellulose fiber used is preferably 30 dtex to 200 dtex, more preferably 30 dtex to 170 dtex, and further preferably 30 dtex to 120 dtex. Further, in the case of the spun yarn, the spun yarns of No. 60 to No. 30 are preferable, and No. 50 to No. 40 are more preferable. By mixing cellulose fibers, it is possible to obtain bottom clothing having excellent hygroscopicity, excellent antistatic properties, and excellent bending softness due to its hygroscopicity.

In the bottom garment of the present embodiment, elastic threads are arranged at least in a part of the body cloth constituting the bottom garment.
The elastic yarn partially arranged on the body cloth of the bottom garment of the present embodiment refers to a fiber having a breaking elongation of 100% or more. The polymer of the elastic yarn and the spinning method are not particularly limited, and examples thereof include polyurethane elastic yarn (also referred to as spandex or spandex fiber), polyether ester elastic yarn, polyamide elastic yarn, and polyolefin elastic yarn. For example, polyurethane elastic yarn may be used. , Dry-spun or melt-spun can be used. Further, these elastic yarns may be covered with non-elastic yarns in a covering state. Further, so-called rubber threads, which are in the form of threads made of natural rubber, synthetic rubber, and semi-synthetic rubber, can be used, but polyurethane elastic threads, which are excellent in elasticity and are generally widely used, are preferable. Among them, the diol component constituting the polyurethane polymer preferably has a side chain, more preferably the side chain is a methyl group, and further preferably having two methyl groups on the same carbon.

The breaking elongation of the elastic yarn is preferably 400% to 1000% from the viewpoint of giving the fabric good elasticity. The elongation at break is a value measured by the method described in JIS L1013 8.5.1 Tensile strength and elongation.
It is preferable that the elastic yarn does not impair its elasticity at around 180 ° C., which is a normal treatment temperature in the presetting process during dyeing. In addition, elastic yarn having functionality such as high settability, deodorant property, antibacterial property, hygroscopic property, and water absorption to which a special polymer or powder is added can also be used. Regarding the fineness of the elastic thread, it is possible to use a fiber of about 10 dtex to 700 dtex (decitex, hereinafter the same symbol is used), and when looping with the elastic thread, it is preferable to use an elastic thread of about 12 dtex to 250 dtex. When the elastic yarn is inserted and knitted using a Raschel knitting machine, it is preferable to use an elastic yarn of 70 dtex to 700 dtex.

A woven fabric or a knitted fabric is used as the body cloth mainly constituting the bottom garment of the present embodiment, and is appropriately selected depending on the item. Knitting is preferable from the viewpoint of elasticity.
In the case of warp knitting, a structure in which elastic yarn is inserted or looped by a Raschel knitting machine or a tricot knitting machine is preferably used. For Raschel's tissue, a tissue with thick spandex fibers inserted such as 6-course satin, 4-course satin, 6-course tulle, and triconette is preferably used, and a tissue with two spandex inserted and stretched vertically and horizontally is a point of wearing feeling. Especially preferable. For tricots, half tricots, double stitches, atlas structures and the like are preferable because they have good elasticity.
In the case of a circular knit, it is preferable that the elastic yarn is looped.
As the body cloth, a woven fabric in which elastic fibers are woven is also preferably used, and a woven fabric in which elastic fibers are woven into both warp and weft is particularly preferable.

As a product for general consumers, the body dough of the present embodiment preferably has a stress at 50% elongation in the horizontal direction of 0.3N to 3N, more preferably 0.3N to 2.5N, and even more preferably. Is 0.5N to 1.5N. The tensile stress is measured by using a Tensilon tensile tester to stretch a 2.5 cm wide fabric gripped at a gripping interval of 10 cm at a tensile speed of 300 mm / min and read the stress with a stretch ratio of 50%. When the stress at the time of 50% extension of the body cloth in the horizontal direction is 3N or less, the tightening at the time of wearing is not too strong and it is comfortable. On the other hand, if the stress at the time of 50% elongation of the body cloth in the horizontal direction is 0.3 N or more, the compensation effect is high. Further, as a product for athletes having a large amount of muscle, the stress of the body cloth at the time of 50% elongation in the horizontal direction is preferably 0.3N to 5N, more preferably 0.3N to 4.5N. More preferably, it is 0.5N to 4.0N.
Further, the stress at the time of 50% elongation of the body cloth in the vertical direction is preferably 0.3N to 4N. When the stress at the time of 50% extension in the vertical direction is 4N or less, the movement followability at the time of movement such as sitting or crouching is enhanced. On the other hand, when it is 0.3N or more, the compensation effect is enhanced. In the present specification, the "horizontal direction" refers to the peripheral direction of the bottom product (the direction around the human body when worn), and the "vertical direction" refers to the vertical direction of the bottom product (the direction of the human body height when worn). Point to.

When used for inners such as girdles and shorts, it is preferable that the hem on the leg side has a hem structure formed by pulling out threads and a free-cut structure that can be used without fraying or curling of threads on the cut surface. .. By using these, since it is not necessary to sew the end portion, it is possible to prevent the end portion from becoming thick and to prevent the end portion from hitting the skin and leaving a mark on the skin. In addition, the line does not echo on the outer and it is excellent in aesthetics. As the free-cut material, for example, a mixed material of polyurethane and inelastic fiber, which is easily heat-sealed, is preferably used, and nylon or polyester is preferably used as the inelastic yarn.

The bottom garment of the present embodiment is characterized by having a double structure in which the inner fabric is overlapped on the inside of the body fabric (on the human body side when worn).
As the inner fabric, a woven fabric or a knitted fabric is used and is appropriately selected depending on the product, but a knitted fabric is preferable from the viewpoint of elasticity. In the case of warp knitting, a structure in which elastic yarn is inserted or looped by a Raschel knitting machine or a tricot knitting machine is preferably used. For Raschel's tissue, a tissue with thick spandex fibers inserted, such as 6-course satin, 4-course satin, 6-course tulle, and triconette, is preferably used, and a tissue with two spandex inserted and stretched vertically and horizontally is worn. Especially preferable from the viewpoint of feeling. In the jacquard raschel, there may be a difference in the tensile stress of the dough within the inner dough panel. As the tricot structure, half tricot, double stitch, atlas structure and the like are preferable because they have good elasticity. In the case of a circular knit, it is preferable that the elastic yarn is looped. As the inner fabric, a woven fabric in which elastic fibers are woven is also preferably used, and a woven fabric in which elastic fibers are woven into both warp and weft is particularly preferable.

The stress at the time of 50% elongation of the inner fabric in the horizontal direction of the present embodiment is 0.3 to 1.6 times, preferably 0.3 times to 1.6 times the stress at the time of 50% elongation of the body fabric in the horizontal direction. It is 1.3 times, more preferably 0.3 times to 1.1 times, still more preferably 0.3 times to 0.9 times, and most preferably 0.5 times to 0.9 times. If the stress at 50% elongation in the horizontal direction of the inner fabric is less than 0.3 times the stress in the horizontal direction of the body fabric, the support effect is inferior, while the stress at 50% elongation in the horizontal direction of the inner fabric is If it exceeds 1.6 times the stress in the horizontal direction of the body cloth, the stress of the inner cloth is too strong and the comfort is inferior.

In the inner fabric of the present embodiment, the area covered by the inner fabric is preferably 60% or less of the area of the buttocks from the viewpoint of efficiently exerting the external rotation force or the internal rotation force. As used herein, the term "buttocks" refers to the area from the left and right sides of the human body and the ridge plane (waist) to the gluteal sulcus. If the inner fabric is 60% or less of the area of the buttocks, the stretch balance of the inner fabric is likely to change when worn, and the force to pull the thighs outward or inward becomes stronger, which is effective, and is effective at 50% or less. It is more preferable to have it.

The width of the inner fabric in the vertical direction of the product is preferably 5 cm to 20 cm, more preferably 5 cm to 18 cm. If the width of the inner fabric in the vertical direction is 5 cm or more, there is a sufficient covering area for the body, the stretching force when the fabric is stretched is likely to be applied to the body, and the external rotation effect or the internal rotation effect is likely to be exhibited. .. On the other hand, if the width of the inner fabric in the vertical direction is 20 cm or less, the stretch balance of the inner fabric is likely to change when worn, and the force to pull the thighs outward or inward becomes stronger, resulting in an external rotation effect or an internal rotation effect. Is easy to demonstrate.

The inner cloth of the bottom garment of the present embodiment is arranged inside the body cloth, and is characterized in that at least a part thereof is not adhered to the body cloth. Here, "not adhered" means that the fabrics are not always in close contact with each other and fixed by means such as sewing or bonding, and the fabrics are floating.

By stacking at least a part of the inner dough whose stretching stress is 0.3 to 1.6 times that of the body dough without adhering to the body dough, the effect of rotating the legs is exhibited. Further, since at least a part of the inner fabric is not adhered, the stretch balance of the inner fabric changes from the front side to the buttocks side when worn / stationary, so that a force for pulling the thigh portion to the outside or the inside is generated.

Further, when walking, the inner fabric shifts according to the movement, and the expansion balance of the inner fabric changes significantly from the front side to the buttocks side as compared with the resting state, so that a force for pulling the thigh portion further outward or inward is generated. Due to the effect of pulling the thigh, an external or internal rotational force is generated on the lower leg, and a force for opening or closing the leg is generated. It is thought that this action leads to an increase in stride length and walking speed. In addition, by applying an external rotation force to the X leg and an internal rotation force to the O leg, the position of the femur is corrected in the normal direction, and it becomes easier for the foot to come out when standing, such as walking. Furthermore, it is thought that it will lead to an increase in stride length and walking speed.

In particular, since at least a part of the inner fabric is not adhered to the body fabric, the effect of turning the foot by always pulling with the inner fabric independently of the body fabric (not following) can be obtained.

In the bottom garment of the present embodiment, as shown in FIG. 3, the vertical center line of the inner fabric is located on the side portion of the bottom garment on the lower side in the vertical direction than the portion corresponding to the greater trochanter.
The vertical center line is a line connecting the central portions of the inner fabric in the vertical direction, and is indicated by a fine dotted line in the figure.
By arranging the inner fabric so that the center line in the vertical direction is located under the greater trochanter of the wearer, it is possible to apply a tightening force to the position closer to the greater trochanter in the femur, and the lateral direction (outside). The femur can be efficiently swiveled by a force from the inside to the inside or a force from the inside to the side. As a result, a corrective effect on the O-leg and the X-leg can be expected, and the lower limbs can be properly swiveled so that the position of the pelvis can be kept in the correct position.

It is preferable that the upper end portion of the inner fabric is located on the side portion of the bottom garment on the lower side in the vertical direction than the portion corresponding to the greater trochanter.
By arranging the inner fabric so that the upper end is located below the greater trochanter in the vertical direction on the side, the corrective effect can be obtained without applying a tightening force to the greater trochanter. Sometimes it is hard to hinder movement and it becomes a bottom that is easy to move.

Further, it is preferable that the shortest distance between the upper end portion of the inner fabric and the greater trochanter equivalent portion in the armpit portion is 0 to 10 cm.
The corrective effect can be efficiently obtained by applying a tightening force to the femur at a site closer to the greater trochanter.

Examples of preferable arrangement of each member in the bottom garment of the present embodiment are shown in FIGS. 3 to 11.
In FIGS. 3 to 6, the inner fabric is arranged so as to cover the lower part of the buttocks or the thighs from the waist or the inguinal region. In the arrangement of this fabric, the inner fabric is pulled from the waist or groin toward the lower buttocks or thighs when worn, and a force that pulls the thighs outward (external rotation force) is generated, so that the foot is removed. The effect of turning is obtained.
When the arrangement of the inner fabric is as shown in FIG. 3, A>B> C, and when the distance between the greater trochanter and the upper end of the inner fabric is short, the external rotation force is effectively generated.
When the arrangement of the inner fabric is in FIG. 4, A = B> C, and a lower external rotation force than in FIG. 3 is generated.
When the arrangement of the inner fabric is shown in FIG. 5, A>B> C, but the inclination of the inner fabric is smaller than that of FIG. 3, and a lower external rotation force than that of FIG. 3 is generated.
When the arrangement of the inner fabric is shown in FIG. 6, A>B> C, but since the upper end of the inner fabric or the vertical center line of the inner fabric comes upward from the greater trochanter corresponding portion, it moves more than in FIG. I feel difficult. When the upper end of the inner fabric is upward above the greater trochanter equivalent, an external rotation force lower than that in FIG. 3 is generated, and the upper end of the inner fabric and the vertical center line of the inner fabric are higher than the greater trochanter equivalent. When it comes in the upward direction, it is difficult for external rotation force to be generated.

In FIGS. 7 to 11, the inner fabric is arranged so as to cover the front part of the thigh part or the inguinal region to the lower part of the buttocks or the rear part of the thigh part. In the arrangement of this fabric, the effect of inwardly rotating the foot can be obtained by generating a force (internal rotation force) that pulls the inner fabric from the lower part of the buttocks or the rear part of the thighs to the front part of the thighs or the inguinal region when worn. ..
When the arrangement of the inner fabric is as shown in FIG. 7, B> A and B> C, and when the distance between the greater trochanter and the upper end of the inner fabric is short, the internal rotational force is effectively generated.
When the arrangement of the inner fabric is in FIG. 8, A = B = C, and a lower internal rotational force than in FIG. 7 is generated.
When the arrangement of the inner fabric is shown in FIG. 9, B <A and B <C, and a lower internal rotational force than in FIG. 8 is generated.
When the arrangement of the inner fabric is shown in FIG. 10, B> A and B> C, but the inclination of the inner fabric in the front portion is smaller than that in FIG. 7, and a lower internal rotation force than in FIG. 7 is generated.
When the arrangement of the inner fabric is shown in FIG. 11, B> A and B> C, but the inclination of the inner fabric on the back surface is smaller than that in FIG. 7, and a lower internal rotation force than in FIG. 7 is generated.

In the bottom garment of the present embodiment, the area ratio of the portion of the inner fabric that is not adhered to the body fabric is preferably 70% or more, more preferably 80% or more, and further, with respect to the total area of the inner fabric. It is preferably 90% or more. When the area ratio is 70% or more, the effect of rotating the foot can be obtained and the bottom is easy to move, which is preferable.

Adhesion is preferably performed at several ends of the inner fabric, for example, the upper end, the lower end, the side edges (the left and right ends of the inner fabric, the adhesive with the crotch, the front panel (tummy holding panel or). The adhesive portion with the panel) is collectively referred to as a side end portion. See FIG. 3).
Of the edges of the inner fabric, 20% to 70% are preferably not adhered, and the non-adhesive portion is preferably the lower end of the inner fabric. Further, when the ratio of the end portion not adhering to the body fabric of the inner fabric to the total length of the lower end portion of the inner fabric is 20% to 100%, the expansion balance of the inner fabric changes from the front side to the buttocks side. Is preferable because the force that pulls the thigh portion outward or inward becomes strong. The bonded portion and the non-bonded portion may be continuous or discontinuous.

In particular, in the bottom garment of the present embodiment, it is preferable that 80% or more of the side end portion of the inner fabric on the back surface of the bottom is adhered to the body fabric at the thigh portion.
By arranging the inner fabric so that the inclination from the side to the thigh becomes large, the effect of rotating the foot can be obtained.

When a tummy holding panel is installed on the front surface with a girdle or the like, it is preferable that the side edges of the inner fabric are adhered to the left and right parts of the panel. The width of the panel in the product vertical direction is preferably 5 cm to 20 cm, and it is preferable that the inner fabric is adhered to one side of the front panel, passes through the back center, and is adhered to the front panel on the other side. When the tummy holding panel is not installed on the front surface of a sports bottom or the like, it is preferable that the upper end and the side end of the inner fabric are adhered to the waist portion or any part of the body fabric. The left and right inner fabrics may overlap.

In order to generate the above-mentioned external rotation force, 70% or more of the adhesive portion of the side end portion of the inner fabric is above the horizontal line passing through a point 5 cm above the crotch portion on the front surface of the bottom garment when placed flat. It is preferably located at. The crotch portion indicates an apex divided into two crotches in the lower part of the bottom shown in FIG. As shown in FIG. 3, the portion indicated by the thick solid line at both ends of the inner fabric is the adhesive portion of the side end portion, and 70% of this thick solid line is above the horizontal line passing through the point 5 cm above the crotch portion. If it is located, external rotation force is likely to occur.
When the end portion of the inner fabric is above the area 5 cm above the crotch portion, the extension of the inner fabric on the front surface is smaller than that on the back surface, so that an external rotation force is generated at the time of wearing.

In particular, in the bottom garment of the present embodiment, as shown in FIG. 3, the highest point in the vertical direction of the side end portion of the inner fabric on the front surface of the bottom garment is A, and the highest point in the vertical direction of the inner fabric on the side portion of the bottom garment is B. When the uppermost point in the vertical direction of the side end portion of the inner fabric on the back surface of the bottom garment is C, the height in the vertical direction is preferably A>B> C.
Since the upper front part, the side part, the back part and the inner fabric are present in a spiral shape, the thigh part can be pulled outward when worn to effectively generate an external rotational force.

Further, it is preferable that the inner fabric is adhered to the body fabric on the front surface of the bottom garment on the upper side in the vertical direction with respect to the plane perpendicular to the vertical direction of the bottom garment including the crotch portion.
In the arrangement of this fabric, the amount of elongation of the fabric at the portion corresponding to the lower part of the buttocks of the inner fabric when worn is larger than the amount of extension from the waist to the buttocks. The effect of externally rotating the foot can be obtained by generating a force (external rotation force) that pulls the portion outward.

Further, in order to generate an internal rotational force, 70% or more of the adhesive portion of the side end portion of the inner fabric is below the horizontal line passing through a point 5 cm above the crotch portion on the front surface of the bottom garment when placed flat. It is preferable that it is adhered to. As shown in FIG. 5, the portion indicated by the thick solid line at both ends of the inner fabric is the adhesive portion of the side end portion, and 70% of this thick solid line is below the horizontal line passing through the point 5 cm above the crotch portion. If it is located, internal rotational force is likely to occur.
When the end portion of the inner fabric is below the region 5 cm above the crotch portion, the extension of the inner fabric on the front surface is larger than that on the back surface, so that an internal rotation force is generated at the time of wearing.

In particular, in the bottom garment of the present embodiment, as shown in FIG. 7, the highest point in the vertical direction of the side end portion of the inner fabric on the front surface of the bottom garment is A, and the highest point in the vertical direction of the inner fabric on the side portion of the bottom garment is B. When the uppermost point in the vertical direction of the side end portion of the inner fabric on the back surface of the bottom garment is C, it is preferable that the height in the vertical direction is B> A and the height in the vertical direction is B> C.
Since the inner fabric arrangement from the front to the side is B> A, B becomes a position closer to the greater trochanter, and the thigh can be pulled inward when worn to effectively generate an internal rotational force. Further, by setting B> C on the back surface, the bottom does not hinder the movement during operation and the bottom is easy to move.

Further, it is preferable that 80% or more of the side end portion of the inner fabric on the front surface of the bottom is adhered to the body fabric at the thigh portion.
From the front side to the side part, the inclination of the inner fabric becomes large, and the correction effect can be enhanced.

Adhesion can be done by sewing, bonding, etc., but a method that does not impair the elongation of the fabric is preferable, two-needle stitching or staggered stitching is preferable for sewing, and bonding is performed with a width of 0.5 cm to 1.5 cm for bonding. It is preferable to do it. Adhesion by bonding is more preferable because the step in the bonded portion is eliminated as compared with the case of sewing. It is also preferable to use a free-cut material for the inner fabric because the step at the end is eliminated.

The pressure applied to the buttocks of the bottom garment of the present embodiment is preferably 5 hPa to 20 hPa, more preferably 8 hPa to 18 hPa. The pressure on the buttocks is the average of the pressure on the left and right at the tops of the left and right mountains (hip tops) at the position where the circumference of the buttocks is the largest. It is attached and measured with an air pack type pressure gauge. In addition, for L size bottom clothing, it is attached to an L size standard body type mannequin and measured. When the pressure on the buttocks is 5 hPa or more, the pressure is sufficiently large and the effect of rotating the foot is high, which is preferable. On the other hand, when the pressure applied to the buttocks is 20 hPa or less, it is preferable without hindering the movement during exercise.

It is preferable that the bottom clothing for athletes has a slightly stronger pressure from the viewpoint of supporting exercise performance, and the pressure on the buttocks is preferably 10 hPa to 20 hPa. In the case of bottom clothing for athletes, polyester fibers are desirable as the inelastic yarn used for the body fabric or the inner fabric from the viewpoint of sweat treatment.
The bottom clothing for the elderly is preferably worn with a slightly weaker pressure, and the pressure on the buttocks is preferably 5 hPa to 15 hPa. When the pressure on the buttocks is within the above range, the ease of wearing is also improved.

<< First Example >>
Hereinafter, the first invention will be specifically described with reference to Examples and Comparative Examples. The extensional stress was measured in Examples and Comparative Examples as follows.

(1) 50% and 80% elongation stress and elongation recovery rate in the vertical and horizontal directions Using a Tencilon tensile tester, a 2.5 cm wide fabric gripped at a gripping interval of 10 cm is stretched at a tensile speed of 300 mm / min. Elongation with a rate of 0% to 80% and recovery with an elongation rate of 80% to 0% are repeated three times, and the extension load and recovery load are measured in each of the vertical and horizontal directions, and an extension recovery curve is drawn. The stress of the elongation rate of 50% and 80% in the first extension is read, and the extension load is 50% and 80% in the vertical and horizontal directions. If the gripping length of 10 cm cannot be secured due to the convenience of the product form, the gripping interval is set as possible. If the width cannot be secured at 2.5 cm, the measured width is calculated by converting it to 2.5 cm by the following formula.
Elongation load [cN] at 2.5 cm width = {2.5 cm / (measured fabric width [cm])} × Elongation load by measurement [cN]
For the elongation recovery rate, read the third residual elongation (%) from the elongation recovery curve in the elongation stress measurement in each of the vertical and horizontal directions, and use the following formula:
Elongation recovery rate (%) = {[80- (residual elongation)] ÷ 80} × 100
The elongation recovery rate (%) in the vertical direction and the horizontal direction was calculated by.
The fabric used for the measurement is sampled from the bottom garment so as not to partially include a portion having a high elongation stress such as an adhesive portion or an embroidered portion.

(2) Percentage of the area of the inner fabric that is not adhered to the body fabric The area that overlaps the body fabric of the inner fabric is S (cm ² ), the area of the adhesive part is S'(cm ² ), and then formula:
Percentage of the inner fabric that is not adhered to the body fabric = (SS') / S × 100 (%)
Calculate with.
If the areas S and S'cannot be obtained, the above ratio is calculated by obtaining the weight of the paper pattern or the cloth corresponding to the area of the paper pattern or the area of the cloth, and replacing the area of the above formula with the weight.

(3) Percentage of non-adhesive body fabric at the lower end of the inner fabric The ratio of non-adhesive body fabric at the lower end of the inner fabric is the end part (not including the side edge) that is arranged downward when the inner fabric is worn. ) Is P (cm), and the end that is placed downward and adhered to the body cloth when worn is P'(cm).
Percentage of non-adhesive to body fabric at the lower end of the inner fabric = (PP') / P × 100 (%)
Calculate with.

(4) Area ratio where the inner fabric covers the buttocks At the bottom, the area of the buttocks area surrounded by the waist, left and right side lines, and gluteal sulcus is K (cm ² ), and the area where the inner fabric exists within this area is K. '(Cm ² ) and the following formula:
Area ratio where the inner fabric covers the buttocks = K'/ K x 100 (%)
Calculate with.
At the time of calculating this area, the mannequin corresponding to the M size was made to wear the bottom, and the K of the bottom was measured with respect to the buttock region K'of the mannequin.

(5) Pressure: Connect to the pressure measuring device AMI-3037-10 manufactured by AMI Techno Co., Ltd. on the left and right hip tops (the apex of the bulge of the buttocks) and the abdomen (3 cm below the navel) of the standard M size mannequin. The pressure (kPa) when the M size of the bottom garment of the present embodiment is put on the attached air pack is measured repeatedly for desorption three times, and the average thereof is calculated.

(6) Hip joint torque Five subjects aged 20 to 40 years were made to wear bottom clothing, and using HUMAC NORM (manufactured by CSMi), the angle between the hip joint and the thigh in the supine position was set to neutral 0 °, and the thigh. When the hip joint and the thigh were bent until the angle formed by the hip joint and the thigh became 120 ° in the form of raising the portion, the measurement was performed using the force applied when raising the leg in the central portion of the thigh as a torque.

(7) Knee angle Θ
Five subjects aged 20 to 40 years were made to wear bottom clothing, and in a stationary standing state, they were attached with reflex markers at the iliac point, the center of the patella, and the lateral malleolus point as shown in FIG. The measurement was performed with VINUS3D: manufactured by Novitec Co., Ltd., and the knee angle formed from the iliac point, the center of the patella, and the lateral malleolus point (Θ shown in FIG. 12: representing the internal angle of the knee seen from the front) was measured. The degree of effect was calculated by the following formula.
Knee angle Θ [°] = (angle from iliac point, center of patella, and lateral malleolus when wearing bottom clothing)-(angle from iliac point, center of patella, and lateral malleolus when not wearing)
When the external rotation force works and the knee is externally rotated, Θ becomes a negative value, and when the internal rotation force works and the knee is internally rotated, Θ becomes a positive value. Further, the larger the absolute value of Θ, the greater the action of internal rotation or external rotation.

(8) Feeling of wearing Five subjects evaluate the overall feeling of tightening, ease of movement, and feeling of leg correction according to the following criteria, and average them.
<Tightening feeling>
5: Very comfortable 4: Somewhat comfortable 3: Neither can be said 2: Somewhat uncomfortable 1: Very uncomfortable <Easy to move>
5: Very easy to move 4: Easy to move 3: Neither can be said 2: Slightly difficult to move 1: Very difficult to move <correction feeling>
5: I feel very corrective power 4: I feel corrective power 3: I can't say either 2: I feel a little corrective power 1: I don't feel too much corrective power

<< Second Example >>
Next, the second embodiment of the present invention will be described more specifically with reference to Examples and Comparative Examples. However, the present embodiment is not limited to the following examples as long as it does not deviate from the gist thereof. The physical properties in the examples were measured by the following methods.

(1) Elongation stress and elongation recovery rate of 50% in the horizontal direction Using a Tensilon tensile tester, a 2.5 cm wide cloth gripped at a gripping interval of 10 cm has an elongation rate of 0% to 80% at a tensile speed of 300 mm / min. Elongation and recovery with an elongation rate of 80% to 0% are repeated three times, stress during elongation and stress during recovery are measured in the horizontal direction, and an elongation recovery curve is drawn. The stress with an elongation rate of 50% in the first extension is read and used as the extension stress of 50% in the horizontal direction. If the gripping length of 10 cm cannot be secured due to the convenience of the product form, the gripping interval should be 5 cm or the like.
For the elongation recovery rate, read the third residual elongation (%) from the elongation recovery curve in the elongation stress measurement in the horizontal direction, and use the following formula:
Elongation recovery rate (%) = {[80- (residual elongation)] ÷ 80} × 100
The elongation recovery rate (%) in the vertical direction and the horizontal direction was calculated by. The fabric used for the measurement is sampled so as not to partially include a portion having a high elongation stress such as an adhesive portion or an embroidered portion.

(2) Distance between the vertical center line of the inner fabric and the upper end of the inner fabric and the part corresponding to the greater trochanter. The point 10 cm above the crotch in the horizontal distance is defined as the greater trochanter-equivalent part. With the bottom garment worn on the torso, the vertical distance between the center line in the vertical direction of the inner fabric and the upper end portion of the inner fabric and the portion corresponding to the greater trochanter is measured.

(3) Height of the highest point in the vertical direction With the bottom garment turned over and placed on the desk, measure the vertical distance from the hem on the side of the bottom garment to the adhesive part between the body cloth and the inner cloth. The side part of the bottom garment indicates a part that appears as a side line when the bottom garment is placed on the desk with the front center and the back center of the bottom garment overlapped.

(4) Pressure on the left and right hip tops (the apex of the bulge of the buttocks) and the abdomen (3 cm below the navel) of the C70 size lower body torso made by Kiya Co., Ltd. The air pack connected to -10 is attached, and the pressure (kPa) when the M size of the bottom garment of the present embodiment is worn is measured repeatedly for desorption three times, and the average thereof is calculated.

(5) Stride difference, walking time difference Five subjects aged 20 to 60 wear bottom clothing, measure the time T and stride Q when walking a course of 800 m per lap, and wear only shorts. The difference between the time T1 and the stride Q1 is obtained. In each case, each subject should wear the same untightened long pants, T-shirt, and athletic shoes as outerwear.
Stride difference = Q-Q1 (cm)
Walking time difference = T1-T (sec)

(6) Knee angle Θ
Five subjects aged 20 to 60 years were made to wear bottom clothing, and in a stationary standing state, as shown in FIG. 12, they were attached with reflex markers at the iliac point, the center of the patella, and the lateral malleolus point, and a motion analysis system (motion analysis system). The measurement is performed by VINUS3D: manufactured by Novitec Co., Ltd., and the knee angle formed from the iliac point, the center of the patella, and the lateral malleolus point (Θ shown in FIG. 12: representing the internal angle of the knee seen from the front) is measured. The degree of effect is calculated by the following formula.
Knee angle Θ [°] = (angle between iliac point, center of patella, and lateral malleolus when wearing bottom clothing)-(angle between iliac point, center of patella, and lateral malleolus when not worn)
When the external rotation force works and the knee is externally rotated, Θ becomes a negative value, and when the internal rotation force works and the knee is internally rotated, Θ becomes a positive value. Further, the larger the absolute value of Θ, the greater the action of internal rotation or external rotation.

(7) Average muscle activity When a subject in his twenties wears bottom clothing and runs at a speed of 12 km / hr on a tread mill, a myoelectric evaluation device (Personal-EMG plus: Oisaka Electronics Co., Ltd.) The muscle activity amount E of the rectus femoris muscle, the gluteal muscle, and the biceps femoris muscle is measured, respectively, and the degree of change from the muscle activity amount E1 when wearing only shorts is calculated from the following equation.
Average muscle activity [% CTRL] = (E / E1) x 100
In order to distinguish between the stance phase and the swing phase, the state of treadmill running is photographed with a high-speed camera, and the value of each muscle activity is obtained by integrating only the stance phase in the running cycle. Let E be the average value of muscle activity in 3 running cycles. The rectus femoris, gluteus maximus, and biceps femoris are muscle groups involved in flexion and extension of the lower limbs. It can be said that energy consumption is low in driving and efficient driving is possible.

(8) Feeling of wearing Five subjects evaluate the feeling of tightness of the buttocks, ease of movement, and feeling of fatigue according to the following criteria, and average them.
<Tightening feeling>
5: Very comfortable 4: Somewhat comfortable 3: Neither can be said 2: Somewhat uncomfortable 1: Very uncomfortable <Easy to move>
5: Very easy to move 4: Easy to move 3: Neither can be said 2: Slightly difficult to move 1: Very difficult to move <Fatigue>
5: Very low fatigue 4: Low fatigue 3: Neither can be said 2: Slightly tired 1: Very tired
