Description

The present invention relates mainly, but not exclusively, to garments for the lower body of women, particularly those having a panty portion and a leg length from below the knee to the ankle, for room wear or inner wear (especially for sleeping). It is a garment for the lower body, represented by leggings worn as nightwear, which has less tightness around the abdomen and less discomfort in wearing, and has gradual compression from the ankle to the thigh through the calf. To provide comfortable lower-body clothing capable of providing foot care for firmly tightening from an ankle to a thigh by changing a foot. In addition, the lower body garment according to the present invention is not limited in its shape (for example, length), and although it is not particularly limited, it is mainly worn as a nightwear for sleeping. Lower-body clothing such as spats, leggings and torenka (difference from spats and leggings in that torenka has a part that hooks on the arch of the foot). In short, the name is not particularly limited as long as it has a length from the waist to at least above the ankles, and includes a waist portion and panty portion covering the lower abdomen and buttocks of the human body, and a leg portion covering the leg portion of the human body. .

Sports spats or leotards that do not have a portion below the ankle (there is no portion that covers the foot toward the tip of the toe) are known as clothes for aerobics and dance. It is also being used as everyday wear. For example, under a short skirt or dress made of thin fabric, long leggings made of elastic fabric that fit perfectly from the waist to the leg (hereinafter referred to as spat-like lower body clothing including spats) It is popular among young women to wear a skirt and show leggings from under the skirt.

Conventional spat-like lower-body garments of this type are formed by sewing together the fabric parts after cutting stretchable fabric, and sewing lines are formed particularly along the leg portions. In such spat-like lower-body garments, sewing lines are formed along the legs, so when worn as outerwear, the appearance is poor. There is also a problem that the sewn part is stiff (uncomfortable to wear) because it adheres tightly. Furthermore, it has the disadvantage that it requires a lot of time and effort for cutting and sewing, and the manufacturing cost is high.

In view of these points, Japanese Patent Laid-Open No. 6-299401 (Patent Document 1) provides suitable stretchability and contraction force according to each part of the lower leg, can improve the appearance when worn, and can be cut and To disclose a spat-like garment capable of minimizing the labor of sewing and reducing the cost required for manufacturing. This spats-like garment has a pair of legs that are circularly knitted in a tubular shape and shorts that are continuous with the legs. The pair of legs are sewn together along the crotch line of the shorts. It is a spat-like garment characterized in that the number of wales on the shorts side is set larger than the number of wales on the ankle side, corresponding to changes in the circumference of each part of the lower leg of the human body.

In the spat-like garment disclosed in Patent Document 1, there are always sewn parts on the front and back of the shorts, and when worn, these sewn parts hit the center of the abdomen, crotch, and buttocks. , which is inevitably associated with local pressure and pain, and is uncomfortable to wear. In addition, in the spat-like garment disclosed in Patent Document 1, the number of wales is merely changed in accordance with the change in the circumference of each part of the lower leg, and the effect of correcting the body shape of the wearer's body line. Functionality is not considered at all.

In view of this point, Japanese Patent Laying-Open No. 2010-261112 (Patent Document 2) strongly supports the abdomen and buttocks to enable body shape correction, eliminates the need to wear a girdle, and adds elegance to the legs. Disclosed is a lower-body garment (leggings in the embodiment) capable of exhibiting a beautiful leg effect by enhancing fashionability by applying beautiful pattern knitting rich in texture. This lower-body garment is a lower-body garment in which a panty part (shorts part) and a leg part are seamlessly and integrally knitted by double raschel knitting to fit and cover from the waist part to the leg part, and the abdomen and buttocks are tightened. It is characterized by a strong power area with a strong buttocks, a middle power area with a medium tightening force on the left and right bulges of the buttocks, and a weak power area with a weak tightening force on the legs. do.

Here, the power refers to tightening force, tightening pressure, etc., and the strength of the power can be changed by changing the knitting density, changing the knitting structure, changing the number of knitting yarns, and changing the type of knitting yarn. , to set strong power, medium power, and weak power by adopting appropriate means.

JP-A-6-299401 Japanese Unexamined Patent Application Publication No. 2010-261112

In the lower-body garment disclosed in Patent Document 2, the panty portion and the leg portion are seamlessly and integrally knitted by double raschel knitting, so there are sewn portions in front and behind the shorts portion as in Patent Document 1. The problem of running out and feeling uncomfortable is solved.
However, in the lower-body garment disclosed in Patent Document 2, the abdomen and buttocks are high power area areas with strong tightening force, the left and right bulges of the buttocks are medium power area areas with medium tightening force, and the leg areas have tightening force. It is merely a weak power area where the power is weak, and it is only intended to strongly support the abdomen and buttocks to shape the body shape. That is, although it is preferable to wear the lower-body garment (leggings) disclosed in Patent Document 2 for body shape correction, when worn as room wear or nightwear, the waist is more likely to be worn than such a body shape correction function. To achieve a function that minimizes the feeling of tightness around the wearer and the discomfort of wearing it, and/or to firmly tighten from the ankle to the thigh by gradually changing the pressure in the area from the ankle to the thigh through the calf. Realizing a foot care function is strongly demanded. Neither Patent Document 1 nor Patent Document 2 disclose or suggest such a thing, and Patent Document 1 changes the number of wales according to the change in the circumference of each part of the lower limb. However, Patent Document 2 discloses that the body shape correction effect on the wearer's body line is such that the power of each part in the abdomen and buttocks increases from the legs to the left and right bulges of the buttocks (the pressure is increased in stages). squeezing the abdomen and buttocks).

The present invention has been developed in view of the problems mentioned above, and its object is mainly, but not exclusively, to garments for the lower body of women, in particular from the waist to at least above the ankles. Leggings that are long enough to be worn as loungewear or innerwear (especially nightwear for sleeping), including a waist and panty portion covering the lower abdomen and buttocks of the human body, and leg portions covering the legs of the human body. It is a garment for the lower body represented by , which has less tightening feeling around the abdomen and less discomfort in wearing, and changes the pressure stepwise from the ankle to the thigh through the calf to the thigh. To provide a garment for the lower part of the body which is comfortable to wear and which enables foot care to firmly tighten the body.

In order to achieve the above object, the lower-body garment according to the present invention employs the following technical measures.
That is, the garment for the lower body according to the present invention has a length from the waist to at least above the ankles, and includes a waist portion and a panty portion covering the lower abdomen and buttocks of a human body, and leg portions covering the legs of the human body. A garment for the lower body that is preferably worn, wherein the portions corresponding to the panty portions of a pair of circular knitted fabrics, which are cylindrically knitted in a size corresponding to the leg portion, are cut to form cutting lines. The lower body garment placed on a flat surface with the waist part upward and the leg part downward, instead of the lower body garment having crotch seams sewn together, wherein the lower abdomen and the buttocks The left and right ends of a substantially rectangular circular knitted fabric circularly knitted in a size corresponding to the size corresponding to the circular knitted fabric are cut from the lower end to the portion corresponding to the leg portion, and the cut lines on the front side of the circular knitted fabric are cut. and a sewing line including left and right inner leg lines to which cut lines on the back side of the circular knitted fabric are respectively sewn and a crotch line connecting the left and right inner leg lines, and the crotch sewing line In the circular knitted fabric, at least a part of the leg part and the waist part are less likely to stretch and shrink than the other parts, and the knitted fabric has a large tightening force and is highly stretchable. The circular knitted fabric is formed of a knitted fabric into which elastic yarn is inserted, and when worn, the pressure is increased, and the single circular knitted fabric is placed on a flat surface with the waist portion facing upward and the leg portion facing downward. When the lower side of an approximately isosceles trapezoid having a lower side shorter than the upper side approximately equal to the lateral length of one circular knitted fabric is aligned with the lower side of the one circular knitted fabric, the approximately isosceles trapezoid By cutting off the knitted fabric protruding from the substantially isosceles trapezoid below and sewing with a sewing line including the leg inner line and the crotch line, the pressure on the leg portion is greater than that on the thigh side is characterized by being high on the ankle side.

Preferably, the shorter the lower side of the substantially isosceles trapezoid, the higher the compression on the ankle side.
More preferably, the greater the height of the substantially isosceles trapezoid, the longer the region in which the pressure changes in the leg portion.

According to the garment for the lower body of the present invention, it has a length from the waist to at least above the ankles, and includes a waist portion and a panty portion covering the lower abdomen and buttocks of a human body, and leg portions covering the legs of a human body, and is used as room wear. Or lower body clothing typified by leggings worn as innerwear (especially nightwear for sleeping), which has less tightness around the stomach and less discomfort, and is from the ankle through the calf to the thigh. To provide a comfortable garment for the lower half of the body, which enables foot care to firmly tighten the wearer from the ankle to the thigh by gradually changing the wearing pressure on the part leading to the thigh.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a lower-body garment and a method for manufacturing the lower-body garment according to embodiments of the present invention will be described in detail with reference to the drawings. Here, there are various structures and manufacturing methods of the lower body garment, and the present invention is not limited to a specific structure and manufacturing method. That is, any lower-body garment and any lower-body garment manufacturing method may be used as long as the garment has the characteristics described later. For example, as long as the characteristics described later are provided, the knitting structure of the knitted fabric constituting the lower body garment, the type of knitting machine for knitting the knitted fabric of the lower body garment, and the sewing to form the lower body garment from the knitted fabric Any sewing method (type of sewing machine, etc.) may be used. As such, the following lower body garments and methods of making same are merely exemplary. In the following, sewing, sewing, and stitching, cloth and knitted fabric, and leg portions are not used separately.

The application of the present invention includes, for example, a waist portion and a panty portion covering the lower abdomen and buttocks of a human body, and a leg portion covering the legs of a human body, which has a length from the waist to at least above the ankles, and is preferably used at bedtime. It is particularly preferred for lower body garments worn, and leggings are an example of such lower body garments. However, for example, the length is not limited to the length of leggings, as long as it has a length from the waist to at least above the ankle, and longer torenka, pantyhose, tights, etc. It doesn't matter if it is.

A schematic front view of the lower body garment 100 according to the embodiment of the present invention (the front side (reverse skin contact surface) is shown in FIG. 1A, and a schematic front view (the back side (skin contact surface) is shown in FIG. 1B). As shown in these figures, the lower body garment 100 has a length from the waist (wear opening 112) to at least above the ankle (hem opening 140), and has a waist portion that covers the lower abdomen and buttocks of the human body. 110, a panty portion 120, and a leg portion 130 for covering the legs of the human body, and is preferably worn during sleep. In the following description, this lower-body garment 100 will be described as leggings 100 (conventional leggings 200).

On the other hand, conventional leggings 200, as shown in FIGS. 2(A) and 2(B), have a length from the waist (wearing opening 212) to at least above the ankle (hem opening 240). It includes a waist portion 210 and a panty portion 220 covering the lower abdomen and buttocks and a leg portion 230 covering the legs of the human body. The cuff 240 is folded back and sewn along a cuff sewing line 242 .

Then, as shown in FIG. 2(C), the method for manufacturing the leggings 200 includes (C-1) circular knitting in a size (thickness) corresponding to the leg portion 230 (the diameter of the knitting machine is 3 inches); ~ 3.5 inches) corresponding to the panty portion 220 (more specifically, the waist portion 210 and the panty portion 220) of a pair of circular knitted fabrics (circular knitted fabric 200L and circular knitted fabric 200R) (Fig. 2 2C) are cut (cutting lines are indicated by wavy lines in FIG. 2C), and (C-2) the cutting lines are sewn together to manufacture the leggings 200. FIG. The processing of the waist portion 210 and the processing of the cuff 240 are not described because they have little relation to the present invention. As a result of being manufactured in this manner, the leggings 200 have a crotch seam 222 extending from the abdomen through the crotch to the gluteal cleft.

As a characteristic configuration, the leggings 100 according to the present embodiment are circularly knitted (the knitting machine has a large diameter of about 13 inches) in a size corresponding to the lower abdomen and buttocks (in other words, the waist diameter). ), and there is no crotch sewing line from the abdomen through the crotch to the gluteal cleft. That is, the leggings 100 do not have a crotch seam in the region S shown in FIG. Thus, the region S of the leggings 100 does not have the crotch seam line shown in FIG. 2 (instead of the crotch seam line), but as shown in FIG. 132L and right inner leg line 132R) and a crotch line 122 connecting these left and right inner leg lines (left inner leg line 132L and right inner leg line 132R). More specifically, the leggings 100 are composed of a substantially rectangular piece of circular knitted fabric 100LR that is circularly knitted in a cylindrical shape with a large diameter. The portion 130 is placed on a flat surface with the portion 130 facing downward, and as shown in FIG. ), the cutting lines on the front side of the circular knitted fabric 100LR and the cutting lines on the back side of the circular knitted fabric 100LR are sewn together to form left and right leg inner lines (left leg inner line 132L and right leg There is a sewing line that includes the inside line 132R) and the crotch line 122 connecting these left and right inside leg lines (the left inside leg line 132L and the right inside leg line 132R).

Here, the sewing lines (right and left leg inner lines (left leg inner line 132L and right leg inner line 132R) and these left and right leg inner lines (left leg inner line 132L and right leg inner line 132R) in this leggings 100 ), the front side (skin-contacting reverse side) is arranged so that the appearance (appearance) is given priority over the comfort when worn, and the back side (skin-contacting The surface) is such that the leggings 100 are sewn so that the feel when worn is given priority over the appearance (appearance) (especially by using the third sewing method described later). there is Such differences are not fully represented in FIG.

Here, at least a portion of the leg portion 130 and the waist portion 110 are formed of a knitted fabric that is less stretchable and less likely to shrink than the other portions, and has a large tightening force, so that the wearing pressure is large when worn, and the leg portion 130 Wearing pressure is higher on the ankle side than on the thigh side. Although this will be described in detail later, in the single circular knitted fabric 100LR that constitutes the leggings 100, at least a portion of the leg portion 130 and the waist portion 110 are more difficult to stretch and shrink than the other portions, and have a large tightening force. It is formed of a knitted fabric and has a large amount of pressure when worn, and a part of the leg portion 130 and the waist portion 110 are made of highly stretchable elastic thread (for example, 280 denier (311.08 decitex) polyurethane). It is a knitted fabric in which DCY (Double Covered Yarn, etc.) in which 70 denier (77.77 decitex) nylon yarn is double wound around the yarn is inserted.

Here, one circular knitted fabric 100LR constituting the leggings 100 is placed on a flat surface with the waist portion 110 directed upward and the leg portion 130 directed downward, as shown in FIG. By cutting and sewing a substantially right-angled triangle with the lower end of one circular knitted fabric 100LR as the lower side and the left and right ends as the sides perpendicular to the lower side and sewing, the pressure on the leg portion 130 is lower than that on the thigh side. In this case, the longer the lower side of the substantially right-angled triangle to be cut off, the higher the contact pressure.

As yet another characteristic configuration, in leggings 100 according to the present embodiment, left and right leg inner lines (left leg inner line 132L and right leg inner line 132R) and these left and right leg inner lines (left leg inner line The sewing line including the crotch line 122 that connects the line 132L and the right leg inner line 132R) is a second sewing line that has the effect of preventing fraying from the cutting line shown in FIG. 3(C) by the sewing method 1 to prevent the elastic thread (in this case, DCY) inserted into the knitted fabric from falling off from the fabric on the outer side of the leg from the cutting line. As shown in FIG. 4(A), the front body and the back body are sewn together on the inside of the leg by the second effective sewing method, and formed by the first sewing method and the second sewing method. The left and right leg inner lines (left leg inner lines) are sewn as shown in FIG. 132L and right leg inner line 132R) and the crotch line 122 connecting these left and right leg inner lines (left leg inner line 132L and right leg inner line 132R), without overlapping the knitted fabric. At the section line shown in FIG. 3(A), the first sewing method is used to sew as shown in FIG. 3(C). After that, at the portion on the opposite side of the cutting line from the sewing line by the first sewing method, the knitted fabrics on the front side of the circular knitted fabric 100LR are sewn together by the second sewing method as shown in FIG. The front body and the back body of the leg part 130 which are overlapped and sewn are sewn together as a leg inner line to form one of the left and right cylindrical leg parts (here, the left leg part 130L), and the back side of the circular knitted fabric. The knitted fabrics are overlapped and sewn together, and the front body and the back body of the leg are sewn to form the other left and right tubular leg (here, the right leg 130R), and the knitted fabric of the crotch part are overlapped and a crotch line 122 that connects the left and right inner leg lines is sewn to form a crotch. After that, it is sewn as shown in FIG. 4(C) by the third sewing method, which has a smoothing effect to reduce unevenness of the sewing lines formed by the first sewing method and the second sewing method. ing.

Here, as an example, the first sewing method is overlock, the second sewing method is chain stitch, and the third sewing method is flat seamer.
As another characteristic configuration, in the leggings 100 according to the present embodiment, one circular knitted fabric 100LR constituting the leggings 100 is arranged on a plane with the waist portion 110 directed upward and the leg portions 130 directed downward. Placed on a circular knitted fabric 100LR, the lower side of a substantially isosceles trapezoid having a lower side shorter than the upper side substantially equal to the left and right length of one circular knitted fabric 100LR, as shown in FIG. , the knitted fabric protruding from the substantially isosceles trapezoid below the substantially isosceles trapezoid is cut off. After that, as described above, the left and right leg inner lines (the left leg inner line 132L and the right leg inner line 132R) are connected to the left and right leg inner lines (the left leg inner line 132L and the right leg inner line 132R). By sewing along the sewing line including the crotch line 122, the pressure applied to the leg portion 130 is higher on the ankle side than on the thigh side.

Here, the shorter the lower side of this substantially isosceles trapezoid, the higher the compression on the ankle side of the leg portion 130 , and the greater the height of this substantially isosceles trapezoid, the more pressure is applied on the leg portion 130 . can be lengthened.
The leggings 100 according to the present embodiment having the characteristic configuration as described above will be described in more detail with reference to FIGS. .

<Inseam cutting process>
As shown in FIG. 3A, after setting one circular knitted fabric 100LR constituting the leggings 100 knitted by a circular knitting machine with a large diameter (the diameter of the knitting machine is about 13 inches), it is left for about 48 hours. The waist portion 110 is directed upward and the leg portion 130 is directed downward, and placed in a rectangular shape on a plane. In this case, the circular knitted fabric 100LR is placed on a flat surface so that the cut bosses (marks) provided at the four corners for twist prevention come to the vertices of the rectangular shape. Then, the left and right ends of one circular knitted fabric 100LR are cut from the lower end to the portion corresponding to the leg portion 130 (the portion indicated by the wavy line with the length C (1) in FIG. 3A). )do. In the circular knitted fabric 100LR, cut bosses (marks) are inserted at a total of 10 locations (four corners, upper end of C(1) cut, both ends of oblique side of cut-off triangle).

Here, an example of knitting of the circular knitted fabric 100LR is as follows. In the process of knitting such a knitted fabric, a cut boss yarn for marking is inserted (inconspicuously as a product) at the position shown in FIG. 3(A).
Although the knitted fabric is an example, it is as follows.
・Other than area G(1) and area G(2) (white background portion SP in FIG. 3(A))
Flat knit Front yarn: 1/16 polyester molle
(Polyester mall single yarn with a metric count of 16)
Lining thread: 20/75FTY (Fitting Yarn)
(FTY consisting of a 20 denier (22.22 decitex) polyurethane thread as the core thread and a 75 denier (83.325 decitex) polyester thread as the sheath thread)
- Area G(1) and area G(2) (hatched portion SG in FIG. 3(A))
Knitting in which rubber thread is inserted into the plain knitted fabric of the white background part SP in FIG. covered DCY)
Moreover, the dimensions are as follows, though they are one example.
・Overall dimensions W = 26 cm, corresponding to the waist circumference
L = M dimension 95 cm, L dimension 102 cm, corresponding to the length
・Rubber insertion knitted fabric dimensions G (1) corresponding to the waist length (rubber width) = M dimension 4 cm, L dimension 4 cm
G (2) corresponding to the strong compression area of the leg = M dimension 47 cm, L dimension 52 cm
・Cut position dimensions C (1) corresponding to the length corresponding to the leg part = M dimension 65 cm, L dimension 72 cm
C(2) = M dimension 35 cm, L dimension 35 cm corresponding to the wearing pressure change area of the leg part
C (3) related to the maximum compression of the leg part = M dimension 3.5 cm, L dimension 3.5 cm

<Hem part cutting process>
Next, as shown in FIG. 3(B), a trapezoidal (substantially isosceles trapezoidal) plate or paper is placed on a flat surface in order to keep the width of the ankle (the length of the hem opening 140) constant. It is applied to one circular knitted fabric 100LR having a rectangular shape, and the triangular portion of the hem is cut off.
In addition, by cutting off the triangular portion of the hem in this way, the width of the ankle (the length of the hem opening 140) can be made constant, and in addition, along the oblique side of the triangle (more specifically, the right triangle) Compression can vary. More specifically, one circular knitted fabric 100LR constituting the leggings 100 is placed on a flat surface with the waist portion 110 directed upward and the leg portion 130 directed downward, as shown in FIG. By cutting and sewing a substantially right-angled triangle with the lower end of one circular knitted fabric 100LR as the lower side and the left and right ends as the sides orthogonal to the lower side, the pressure in the leg portion 130 is more on the ankle side than on the thigh side. In this case, the longer the lower side of the substantially right-angled triangle to be cut off, the higher the contact pressure. For example, by changing the pressure to 11 hPa on the thighs, 16 hPa on the calves, and 21 hPa on the ankles, you can tighten your legs and take care of your tired legs while you sleep. .

<Post-cut processing step: processing the edge by the first sewing method>
Next, for the cutting line cut in the above crotch cutting process and the cut line cut off in the hem cutting process, as an edge treatment (treatment to prevent the stitches from unraveling from the edge), 2 mm While cutting about 3 mm, each side (a total of 4 places on the front side and back side of the circular knitted fabric 100LR) is sewn with an overlock as shown in FIG. 3(C). The sewing at this time is not to sew the knitted fabrics together by overlapping the knitted fabrics.

<Sewing processing of left and right legs: formation of left and right legs while preventing DCY from falling off by the second sewing method>
Next, the state shown in FIG. 3(C) is shifted by 90 degrees to the state shown in FIG. 4(A). Then, as shown in FIG. 4(A), the outer side of the overlock is sewn by chain stitching by overlapping knitted fabrics with a width of 8 mm, for example.
At this time, the elastic thread (here, DCY) inserted into the knitted fabric is prevented from falling off from the knitted fabric at the portion on the opposite side of the cutting line from the sewing line by the first sewing method. As shown in FIG. 4(A) (because the state of FIG. 3(C) is shifted by 90 degrees), the knitted fabrics on the front side of the circular knitted fabric 100LR are overlapped and sewn by sewing method 2 to form a leg portion. The front body and the back body of 130 are sewn together as a leg inner line to form one left and right cylindrical leg (here, left leg 130L), which is also shifted 90 degrees from the state shown in FIG. The knitted fabric on the back side of the circular knitted fabric is overlapped and sewn, and the front body and the back body of the leg are sewn to form the other left and right cylindrical leg (right leg 130R in this case). is formed, and the knitted fabric of the crotch portion is superimposed and the crotch line 122 that connects the left and right leg inner lines is sewn to form the crotch.

<Seam allowance opening process: preparation process for the third sewing method>
Next, the seam allowance formed by the first sewing method of overlocking and the second sewing method of chain stitch is opened. This state is shown in FIG. FIG. 4B is an enlarged view of a region 4B portion of FIG. 4A, showing that the leg portions 130 (more specifically, the left leg portion 130L and the right leg portion 130R) are sewn into a tubular shape. Fig. 10 is a diagram showing the seam allowances of the sewing lines by the first sewing method and the second sewing method.

<Sewing Line Post-Processing: Processing for Smoothing Sewing Lines by the Third Sewing Method>
Next, with the seam allowances of the sewing lines by the first sewing method and the second sewing method left open, a flat seamer is sewn over the overlock and the chain stitch. Sewing with a flat seamer (third sewing method) at this time reduces unevenness of the sewing lines formed by the first sewing method (overlock) and the second sewing method (chain stitch). It has a smoothing effect and has the effect of alleviating the bad touch caused by the sewing line.

<hem sewing process>
Next, as shown in FIG. 5A, the tubular knitted fabric at the hem 140 is folded back as indicated by the black arrow and sewn along the hem sewing line 142 .
<Heat setting pretreatment>
Next, as shown in FIG. 5B, the leggings 100 in the process of being manufactured are set on the flat-foot mold 500 with the crotch sewn on the front side (the leggings 100 are put on the flat-foot mold 500).
<Heat setting treatment>
Next, as shown in FIG. 5(C), the leggings 100 put on the flat-foot type 500 are heat-set to improve the shape stability.

As described above, according to the leggings 100 and the method for manufacturing the leggings 100 according to the present embodiment, the leggings 100 are mainly, but not limited to, women's lower-body clothing, and in particular, the length from the waist to at least above the ankles. and includes a waist and panties covering the lower abdomen and buttocks of the human body and leg parts covering the legs of the human body, and leggings worn as room wear or inner wear (especially nightwear for sleeping) A representative garment for the lower half of the body that is less tight and less comfortable around the abdomen, and that gradually changes the pressure from the ankle to the thigh through the calf to the thigh from the ankle to the thigh.
