It has a pair of side regions D, D located between the central region C and the side regions. More specifically, the waistline expansion / contraction region 8 includes an abdomen central region A, a pair of iliac regions B and B, a back central region C, and a pair of side regions D and D.
The side regions D, D are located at and near the boundary between the front body and the back body. The armpit regions D, D have a front body and a back body when the shorts are placed on a plane with the front body on the upper surface and the back body on the bottom surface in a natural state in which a pulling force is not applied in the circumferential direction of the shorts. It is a region near the fold portion that occurs between, that is, a region including a boundary between the front body and the back body.

In the shorts 1, the abdomen central region A, the pair of iliac regions B and B, the back central region C, and the pair of side regions D and D are all stretchable in the circumferential direction of the waistline portion 7. . The abdomen central region A, the pair of iliac regions B and B, the back central region C, and the pair of side regions D and D are composed of a seamless tubular knitted fabric (fabric) formed by a circular knitting machine or the like. It is preferable that the tightening feeling is further suppressed and the fitting property is improved.
The abdominal central region A is formed in the central region of the front body 2 in the lateral direction Y, as shown in FIGS. 1 and 2A. The abdomen central region A has elasticity in the lateral direction Y of the front body 2, and preferably has elasticity in the longitudinal direction X and the lateral direction Y of the front body 2. The lateral direction Y of the front body 2 and the lateral direction Y of the back body 3 respectively match the circumferential direction of the waistline portion.
As shown in FIGS. 1 and 2A, the pair of iliac regions B and B are formed on both sides of the abdominal center region A in the front body 2 so as to be adjacent to the abdominal center region A, respectively. The iliac region B also has elasticity in the lateral direction Y of the front body 2, and preferably has elasticity in the longitudinal direction X and the lateral direction Y of the front body 2. As shown in FIG. 5, the iliac region B is located in front of the wearer's superior anterior iliac spine 9 and iliac crest 9a when the shorts 1 are worn. Superior anterior iliac spine and iliac crest are anatomical terms. As shown in FIG. 4, the iliac bone has an iliac body that forms the upper part of the acetabulum and a iliac wing that expands in a fan shape above it, and the upper edge of the iliac ridge is the iliac crest 9a. is there. The superior anterior iliac spine 9 is a protrusion at the lower front of the iliac crest 9a.

The back central region C is formed in the central region of the rear body 3 in the lateral direction Y as shown in FIGS. 1 and 2B. The back center region C has elasticity in the lateral direction Y of the back body 3, and preferably has elasticity in the longitudinal direction X and the lateral direction Y of the back body 3.
As shown in FIG. 1, FIG. 2 (a) and FIG. 2 (b), the pair of armpit regions D, D are arranged in the circumferential direction of the waistline region 7 with the iliac region B and the back central region C, respectively. In between, it is formed in a state of being adjacent to the iliac region B and the back central region C. The side region D of the shorts 1 has a portion D1 located on the front body 2 side and a portion D2 located on the back body 3 side of the shorts 1 in a flat state. The armpit region D has elasticity in the lateral direction Y of the front body 2 and the back body 3, and preferably has elasticity in the longitudinal direction X and the lateral direction Y of the front body 2 and the back body 3. There is. The flat state is a state in which the front body and the back body are overlapped and the shorts are naturally contracted.

The abdomen central region A, the iliac region B, the back central region C, and the side region D in the waist elastic region 8 of the shorts 1 of the present embodiment are common in that they have elasticity in the circumferential direction of the waist region. In the iliac region B, the return stress in the circumferential direction of the waistline portion 7 is higher than in the abdomen central region A, the back central region C, and the side region D, and the return stress of the iliac region B is Pb, the abdominal center. When the return stress of the area A is Pa, the return stress of the back central area C is Pc, and the return stress of the side area D is Pd, all of the following relational expressions (1) to (3) are satisfied.
(1) Pb> Pa
(2) Pb> Pc
(3) Pb> Pd

  When the wearer M wears the shorts 1, the entire waistline elastic region 8 is stretched in the circumferential direction. However, when the waistline elastic region 8 has a plurality of regions having different return stresses, the shorts 1 are worn. Among them, the higher the return stress in the waistline stretching region 8, the higher the mounting pressure, and the stronger it hits the wearer's skin. The iliac region B in the waistline elastic region 8 of the shorts 1 according to the present embodiment has elasticity in the circumferential direction of the waistline portion 7 and, at the time of wearing, in front of the upper anterior iliac spine 9 and the iliac crest 9a of the wearer. Since it is a region located at, the return stress of the iliac region B is made higher than that of the abdomen central region A, the back central region C, and the side region D which are other regions of the waist elastic region 8, During the wearing of the shorts 1, the iliac region B strongly abuts on the wearer's upper anterior iliac spine 9 and the region having the iliac crest 9a while being deformed, so that the pelvis of the wearer M is stably held. It In addition to this, the present inventors set the return stress of the iliac region B higher than that of the abdominal central region A, the central back region C, and the side region D, so that the pelvis is excessively forward of the wearer. The present invention has been completed by finding that the pelvic leaning forward can be improved.

According to the shorts 1 of the present embodiment, due to the above-described action, the pelvis is supported by a wide range of pressure from the iliac region B to the side region D to the back central region C when worn, so that the posture compensation effect is obtained. can get. An example of the posture correction effect here is that the posture at the time of walking is improved. A good posture during walking can be expected to have effects such as improvement and improvement of health condition and improvement of appearance.
Moreover, the waistline expansion / contraction region 8 has, between the pair of iliac regions B, the abdomen central region A having a lower return stress than the iliac region B, and is generally arranged on the side of the wearer's torso. In addition, since there is a side region D having a lower return stress than the iliac region B, and the return stress of the back central region C is also lower than that of the iliac region B, as compared with the conventional compensating underwear, The degree of tightening the wearer can be greatly reduced, and a comfortable wearing feeling can be obtained without pressure on the abdomen. That is, it is difficult for the wearer to feel the tightening force, even though the posture correction effect is obtained, and it is possible to use the wearer on a daily basis with a feeling similar to that of normal underwear. Furthermore, since the tightening force of the wearer can be reduced while the effect of adjusting the posture is obtained, the wearing and removing operation of the shorts 1 is easy. For example, operations such as pulling up to the waist when wearing the shorts 1 and pulling down when removing the shorts 1 can be performed easily and smoothly.

  In addition, the shorts 1 is configured such that the waist elastic region 51 is located above the iliac crest 9a of the wearer when the shorts 1 are worn, and when worn, the pair of iliac regions B respectively The size and return stress of each part are set so as to integrally cover the superior anterior iliac spine 9 and the iliac crest 9a, and the iliac region B includes the superior anterior iliac spine 9 and the iliac crest 9a. Has a sufficient width in the vertical direction so as to have both a portion located above the superior anterior iliac spine 9 and a portion located below the iliac crest 9a.

The return stress is an index indicating resistance to contraction force after extension, that is, wearing pressure.
The level of return stress in the abdominal central region A, the iliac region B, the back central region C, and the side region D is compared by comparing the return stress (N) values measured by the following [Return stress (N) measuring method]. Can be determined by In the following [measuring method of return stress (N)], the return stress in the shrinking process is obtained, and it is sufficient that all of the above relational expressions (1) to (3) are satisfied.

[Method of measuring return stress (N)]
Length 50 mm in the longitudinal direction X from each of the abdominal center region A, the iliac region B, the back center region C, and the side region D of the waist elastic region of the shorts in the contracted state (natural state), and coincides with the circumferential direction of the waist portion. A measurement piece having a length of 30 mm in the horizontal direction Y is cut out. For each measurement piece, the short direction of the measurement piece, which corresponds to the circumferential direction of the waist, is aligned with the extension direction, and is placed between the upper and lower chucks of a Tensilon tensile tester ("UCT-100W" manufactured by Orientec Co., Ltd.). , The chuck distance is set to 10 mm. Then, the chuck distance is increased from the initial length (natural length) of the measurement piece from 10 mm to 40 mm at a speed of 300 mm / sec, and then the chuck distance is reduced from 40 mm to 10 mm at a speed of 300 mm / sec. The stress during the stretching process is measured. This expansion / contraction process includes an extension process of increasing the chuck distance to 40 mm and a contraction process of reducing the chuck distance to 10 mm after the extension process. From the S-S curve (stress-strain curve) in the expansion / contraction process, the stress at the time of 2.4 times expansion in the contraction process is obtained, and this is used as the return stress. The stress at the time of 2.4 times extension is the stress at the time of extension to 2.4 times the initial length (10 mm) in the contraction process, and the "time of extension to 2.4 times" is the distance between chucks. Is 24 mm.

  The reason why the return stress is the stress at the “2.4 times extension” in the contraction process is that when the shorts 1 are mounted on a cylindrical body model with a perimeter of 89 cm, the shorts in the contracted state in the flat state shown in FIG. It was determined by the extension of the 1 cm straight line to 2.4 cm. The circumference of 89 cm at the position of the iliac spine of this cylindrical body model is the circumference of the hips of adult women in their 50s to 70s described in "Human Body Dimension Data Book 2004-2006" published by Human Life Engineering Research Center. The median value (without auxiliary plate) was used as the standard.

The abdominal center region A preferably has a lower return stress than the back central region C. That is, when the return stress of the iliac region B is Pb, the return stress of the abdomen central region A is Pa, and the return stress of the back central region C is Pc, it is preferable to satisfy the following relational expression (4).
(4) Pb>Pc> Pa
By satisfying the relational expression (4), the mounting pressure in the abdominal center region A is made lower than the mounting pressure in the back central region C, and the tightening reduction effect that reduces the degree of tightening the wearer is improved. Further, by making the mounting pressure of the iliac region B higher than that of the abdominal center region A and the dorsal center region C, the effect of posture correction is improved and the posture can be recognized on a daily basis. Further, it is more preferable that the relational expressions (1) to (4) are satisfied from the viewpoints of wearing comfort and the tightening reduction effect.

The abdominal center region A preferably has a lower return stress than the back central region C and the side region D. That is, when the return stress of the iliac region B is Pb, the return stress of the abdomen central region A is Pa, the return stress of the back central region C is Pc, and the return stress of the side region D is Pd, the relational expression (4 It is preferable that the following relational expression (5) is also satisfied. With such a configuration, the mounting pressure in the abdominal center region A is made lower than the mounting pressure in the back central region C and the mounting pressure in the side region D, whereby the tightening reduction effect is improved.
(5) Pb>Pd> Pa

  The above-described effect of the shorts 1 is that, in the armpit region D and the back central region C, when the return stress of the armpit region D is higher than that of the back central region C, the return stress of the armpit region D is the central back region. It is performed both when it is lower than C and when the return stress is the same in the armpit region D and the back central region C. However, in the shorts 1 of the present embodiment, the return stress of the armpit region D is reduced. It is lower than the back central region C. In the shorts 1, lowering the return stress in the armpit region D as compared with that in the back central region C allows the pair of iliac regions B to improve the posture while improving the posture of the pelvis while improving the posture. A side region D having a low mounting pressure is provided between each of the iliac regions B and the back central region C to increase the area ratio of the region having a lower mounting pressure than that of the iliac region B, thereby further reducing the feeling of tightening. It is preferable from the viewpoint or from the viewpoint of facilitating the attachment / detachment operation.

In the armpit region D, it is preferable that the return stress in the circumferential direction of the waistline region is lower than that in the back central region C. The return stress in the iliac region B is Pb, the return stress in the abdominal central region A is Pa, and the back region is Pa. When the return stress of the central area C is Pc and the return stress of the side area D is Pd, it is more preferable to satisfy the relationship of the following relational expression (6). With such a configuration, the wearing comfort and the tightening reduction effect are improved.
(6) Pb>Pc>Pd> Pa

  The side regions D and the back center region C may have the same return stress, and the side regions D and the back center region C may not have any difference in their respective configurations. That is, the side area D and the back central area C may form one continuous area having no difference in configuration.

As described above, at the open end of the waist opening 5 of the shorts 1, the annular waist elastic region 51 is formed along the open end, and the waist elastic region 51 extends over the entire circumference of the waist opening 5. Have the same return stress.
A plurality of regions A to D having different return stresses are formed in the waistline stretching region 8, while the waist stretching region 51 has the same returning stress over the entire circumference, thereby suppressing the protrusion of extraneous meat when worn. , Suppresses the silhouette. Here, whether or not the waist elastic region 51 has the same return stress over the entire circumference is determined by the following method. First, in the waist elastic region 51, the central portion of the front body 2 in the lateral direction Y, the central portion of the back body 3 in the lateral direction Y, and the central portion in the lateral direction Y of the side part region D and the lateral direction Y, respectively. From the above, the measurement piece is cut out in the same manner as the above-mentioned [measuring method of return stress (N)], and the above-mentioned "return stress" is measured for each cut out measurement piece. Here, when the length in the vertical direction X of the waist elastic region 51 is less than 50 mm, the measurement piece is cut out so that the length in the vertical direction X becomes maximum.
The return stress of the waist elastic region 51 is preferably 1.0 N or more and 3.0 N or less.

More specifically, as shown in FIG. 3, a region of a predetermined width from one end of a tubular knitted fabric manufactured by a circular knitting machine is folded back to the inner surface side of the knitted fabric, and a region of a predetermined width is folded back. A cylindrical knitted fabric manufactured by a circular knitting machine has a double structure by joining the tip end portions to the unfolded portions at the joining portions 74 and 75 by stitching. A waistline stretching region 8 is formed. The waist stretchable region 8 of the circular knit double structure has the abdomen central region A, the iliac region B, the back central region C, and the side region D, in which each of the double overlapping knitted fabrics is different from the other regions. By having a different knitting structure, it is preferable that the region has a different return stress from other regions.
Since the waistline stretchable region 8 has a circular knit double structure, heat retention can be improved, and it can also be a measure to cool the waist.

From the viewpoint of more reliably exerting one or more of the effects of the shorts 1 described above, the waistline elastic region 8 preferably has the following configuration.

In the shorts 1 of the present embodiment, the abdomen central region A, the iliac region B, the back central region C and the side region D, and the waist elastic region 51 in the waistline elastic region 8 are composed of one continuous knitted fabric. On the other hand, the above-mentioned return stress and stretchability are made different from each other by making the knitting structures in each region different from each other. Therefore, the abdominal center region A, the iliac region B, the back center region C and the side region D, and the waist stretch region 51 in the waistline stretch region 8 and the waist stretch region 51 include a suture portion and the like between the knitting tissues constituting the respective regions. There is no joint. Further, each region can be formed by a knitting structure such as flat knitting, rubber knitting, pearl knitting, float knitting, double ridge knitting, single ridge knitting, etc. It is possible to employ a technique such as using a count yarn, a yarn having a high elastic modulus, or increasing the number of yarns used. On the other hand, in order to set the region where the return stress is low, it is necessary to use a technique such as using a fine count yarn, a yarn with a low elastic modulus, or reducing the number of yarns used. You can
As described above, it is preferable that the knitting structure (knitting method) or the knitting yarns forming the knitting structure be different between the regions having different return stresses in the waistline stretching region 8. Such a configuration is preferable from the viewpoint of suppressing the occurrence of a region having high rigidity at the boundary between the regions, further suppressing the feeling of tightening and further improving the fitting property. In this case, the expression that the knitting structure (the knitting method) or the knitting yarns forming the knitting structure are different from each other means that when the knitting structures are the same but the knitting yarns are different, the knitting yarns are the same but the knitting yarns are the same. It includes cases where the structures are different, and cases where both the knit structure and the knitting yarn are different. The difference in the knitting yarn means that the thickness of the knitting yarn, the elastic modulus of the knitting yarn, the number of fibers of the knitting yarn (the number of fibers appearing in the cross section of the knitting yarn), and the like are 1 or 2 of these. Including cases where the above is different.

In the shorts 1, the waistline portion 7 is composed of a composite fiber having at least two or more fiber materials selected from cotton, polyester, rayon, wool, nylon, acrylic, silk, tencel, and polyurethane. Is preferable, and it is more preferable that the waistline stretching region 8 is composed of such a composite fiber. By using such a composite fiber, texture, water absorption and hygroscopicity can be imparted while maintaining stretchability. In particular, using such a composite fiber in the waistline stretchable region 8 has an advantage that high stretchability can be imparted.
An example of such a composite fiber is a composite fiber in which cotton is wound around an elastic thread made of polyurethane or the like. As the polyester, polyethylene terephthalate is preferable because it is easy to handle as a fiber for clothing.

  In addition, the shorts 1 preferably include deodorant fiber having a deodorizing effect as a constituent fiber thereof. By including the deodorant fiber, it can be used as a measure against unpleasant odor components such as nonenal and isovaleric acid which are included as an aging odor derived from sweat and sebum, and can also serve as a measure for a small amount of incontinence. The part containing the deodorant fiber is not particularly limited, but the girth part 7 including the girth expansion / contraction region 8 which is in close contact with the skin of the wearer, particularly the girth expansion / contraction region 8 and the crotch part 4 is such deodorant. The inclusion of fibers is more preferable from the viewpoint of more efficiently obtaining the above effects. As the deodorant fiber having a deodorant effect, known fibers having such an effect can be used without particular limitation, and for example, catechin, a deodorant component having a deodorant performance for ammonia odor such as phthalocyanine, Fibers adhered to the surface by any method such as coating or spraying, fibers obtained by kneading such deodorant components into the raw material resin, and the like can be used. Among these, it is preferable to use the Deocell fiber in terms of cost, industrialization and functionality. In addition to the above, examples of deodorant components having deodorant performance for ammonia odor include silver, copper, activated carbon, etc. These deodorant components are used alone or in combination of two or more. be able to.

  The present invention has been described above based on its preferred embodiments, but the present invention is not limited to the above embodiments. For example, the shorts 1 according to the above-described embodiment have the waist elastic region 51 in which the return stress extends in the circumferential direction separately from the waistline elastic region 8 at the opening end of the waist opening, but the waist elastic region 51 does not exist. The waist elastic region 8 may reach the opening end of the waist opening. Further, the waistline stretchable region 8 may be formed from a single layer of knitted fabric. Further, the shorts 1 of the above-mentioned embodiment have a shape in which the opening end of the leg opening 6 is located near the base of the thigh of the wearer, but instead of this, the opening end of the leg opening 6 is replaced. May be positioned below the base of the wearer's thigh, so-called one-minute length. Further, although the crotch portion 4 of the above-described embodiment has a double structure as shown in FIG. 3, it may have a single layer structure instead.

Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited to the examples.

[Evaluation]
Regarding the shorts of Example and Comparative Example 1, 1. Evaluate posture correction performance, 2. Feeling of wearing while standing 3. The effect of continuous wearing of shorts was verified.

1. Posture compensation performance (test method)
In the state where the shorts of Example and Comparative Example 1 were directly worn alternately, the pelvic angle was calculated from the position of the marker attached to the body using a three-dimensional motion analysis device (manufactured by VICON), and the influence on the pelvis was verified. did. Specifically, a marker is attached on the upper right anterior iliac spine, the upper right anterior iliac spine, and the sacrum of the subject who wears the shorts of Example or Comparative Example 1, and the coordinates of the marker are measured at 100 Hz. The pelvic angle was calculated. The pelvic angle is defined as the pelvic plane defined by the Helen Hayes method in which the triangle with the upper right anterior iliac spine, the upper left anterior iliac spine, and the sacrum of the subject is defined as the pelvic plane. Was measured as. FIG. 7 shows the result. FIG. 7 also shows the results obtained by confirming the statistical difference between the pelvis angle of the example and the pelvis angle of the comparative example 1 by the paired t-test.

2. Listening to the wearing sensation during standing The wearing sensation during standing was heard from the wearer (test subject) who directly wore the shorts of Example and Comparative Example 1 alternately. At this time, 26 women in their 60s to 70s were used as test subjects. Table 1 shows a list of the feeling of wearing when standing.

3. Verification of effect of continuous wearing of shorts The shorts of the comparative product and the shorts of the example were continuously worn alternately for one week, and the sleep condition of each shorts during the wearing period was evaluated. As the shorts for comparison and comparison, the shorts that the subject usually uses were used. In this evaluation, 60 women in their 50s to 70s were used as subjects. This evaluation was evaluated by the Pittsburgh Sleep Quality Index (PSQI) (Yuriko Doi et al. Japanese Pittsburgh Sleep Questionnaire. Psychiatric Therapeutics 13, 755-763, 1998). The result of each evaluation item of PSQI is shown in FIG. 8, and the result of the total score of PSQI is shown in FIG. In the evaluation results shown in FIGS. 8 and 9, the t-test (corresponding) was used to confirm the significant difference between the two groups in the wearing period of the shorts of the comparative control product and the wearing period of the shorts of the example. The higher the score of PSQI, the more disturbed the sleep is.

In addition to the evaluation of the sleep status, changes in mood during the wearing period of each shorts were evaluated. As a psychological index for this evaluation, using the POMS2 Japanese version shortened version for adults (Profile of Mood States 2) (POMS2 Japanese version manual translated by Kazuhito Yokoyama, published by Kazuhisa Watanabe Kaneko Shobo 2015) The score difference obtained by subtracting the score on the first day of the wearing period from the score at the time when was taken as the evaluation result. The larger the value of the score difference, that is, the more positive the value of the score difference, the more the anger-hostility, confusion-confusion, depression-depression, fatigue-apathy, tension-anxiety mood did not improve. Is shown (the lively item is the opposite). The evaluation result is shown in FIG. In the evaluation results shown in FIG. 10, a t-test (corresponding) was used to confirm a significant difference between the two groups in the wearing period of the usual shorts and the period of the shorts in the examples.
In addition, the wearing feeling of the shorts of the example was heard at the first day of the wearing period and when one week of the wearing period passed. Table 2 shows a list of wearing feelings.

〔Evaluation results〕
1. Posture Compensation Performance As shown in FIG. 7, there is a difference in the pelvis angle between the shorts of the example in which the return stress of the iliac region B in the waist area is increased and the shorts of Comparative Example 1 in which the return stress of the waist area is uniform. I was seen. A positive pelvic angle indicates that the pelvis is leaning backward, and a negative pelvic angle indicates that the pelvis is leaning forward. In the shorts of Comparative Example 1, the pelvis was tilted more forward than when the shorts of Example were worn. From these results, it is understood that the shorts of the example correct the excessive pelvic anteversion and have higher pelvic angle compensation performance than the shorts of the comparative example.

2. Listening to the feeling of wearing when standing up From Table 1, in the shorts of the example, along with the opinion that a good fit was obtained, "being aware of the posture", "feeling that the back is stretched" and "the back is tingling" , Etc. From these opinions, it was suggested that the posture may be conscious by applying an appropriate pressure (wearing pressure) to the iliac region.

3. Verification of Effect of Continuous Wear of Shorts As shown in FIGS. 8 and 9, regarding the total scores of sleep quality, daytime difficulty in awakening, sleep difficulty, and PSQI, in the wearing period of the shorts of the example, the comparison product was compared. The score was significantly lower than the wearing period of shorts. That is, during the wearing period of the shorts of the example, better quality sleep was obtained than when wearing the shorts of the comparative product. It is considered that the improvement in sleep quality is due to the fact that the shorts of the embodiment hardly feel the tightening force.

  As shown in FIG. 10, for the items of depression-depression (question: sad, hopeless, I am miserable, I can not do anything, I am a worthless person) wearing the shorts of the example In terms of the period, the difference in scores was significantly lower than the period of wearing the shorts of the comparative product, suggesting that it was not pessimistic. It is considered that the improvement in mood is due to the improvement in the above-mentioned quality of sleep and the increase in the amount of activity during the daytime linked to this. In addition, from Table 2, as the wearing feeling when the shorts of the example were worn for one week in a row, in addition to the opinion that “they are comfortable to wear”, the opinion that “the posture has been improved, walking is easy, and movement is easy” is confirmed. did it.

[Comparative Example 2]
As Comparative Example 2, a shorts shown in FIG. 11 in which the configuration of the waistline stretching region 8 in the shorts of the example was changed was manufactured. In the shorts of Comparative Example 2, the side region D has a knitting method (similar knitting structure) similar to that of the iliac region B, and the return stress of the side region D and the return stress of the iliac region B are the same. Are almost the same. A region obtained by combining the side region D and the iliac region B is also referred to as a side region E. The dimensions and return stress of each region of the waistline stretching region 8 are as follows. The side region E is a region on the left and right, and the following dimensions show values on only one side.
[Circumferential dimensions of contracted state (natural state)]
Abdominal central area A: 130 mm
Side area E: 95-100 mm
Back central region C: 150 mm
[Dimensions of the waistline in the pseudo-wearing state in the circumferential direction]
Abdominal central area A: 250 mm
Side area E: 180 mm
Back central region C: 270 mm
[Return stress]
Abdominal central region Pa: Return stress 2.75N
Iliac region Pb: Return stress 6.60N
Back central region Pc: Return stress 5.25N
Side area Pd: Return stress 6.60N
Pb = Pd>Pc> Pa

  With regard to the shorts of Example and Comparative Example 2, the ease of daily operation was evaluated by the following method.

4. Evaluation of Ease of Daily Movements when Putting On / Off Shorts Six female subjects in their thirties to fifties were made to wear the shorts of Example and Comparative Example 2 directly on each other, and the putting on and taking off that could occur in daily life With regard to standing and sitting, the easiness of movement was evaluated and the shift of the shorts when the chair was standing and sitting was evaluated. The ease of putting on and taking off was evaluated for ease of putting the legs into the leg opening of the shorts and pulling up the girth while wearing, and pulling down the girth when undressing. The easiness of movement was evaluated on the basis of a subjective rating of “good / slightly good / neither can be said / not so good / not good”. The evaluation result is shown in FIG. In FIG. 12, the evaluation of the displacement of the shorts when the chair is standing and sitting is shown by the five-stage evaluation. “Good” means “no deviation”, “somewhat good” means “not too much deviation”, “not very good”. "Corresponds to" slightly shift "and" bad "corresponds to" shift ".

  In addition, the wearing feeling of the shorts of the example and the comparative example 2 when the chair was put on and taken off and when the chair was standing and sitting was heard. Table 3 shows a list of wearing feelings.

〔Evaluation results〕
4. Evaluation of Ease of Daily Movements when Putting On and Removing Shorts As shown in FIG. 12 and Table 3, the shorts of Example were evaluated to be easy to put on and take off because they were more elastic than the shorts of Comparative Example 2. From the results shown in FIG. 12, particularly, the ease of inserting the leg into the leg opening, raising the waistline portion, and lowering the waistline portion was highly evaluated. Further, the shorts of Example were evaluated to be easier to stand and sit than the shorts of Comparative Example 2, and there was no deviation of the underwear when standing and sitting.

  As shown in FIG. 12 and Table 3, the shorts of the embodiment are designed so that the return stress of the iliac region B is set to be the highest and the return stress of the armpit region D is designed to be slightly low, so that the physical and mental burden is small, In other words, it does not feel pressure and is easy and can be worn for a long time. In addition, easy attachment / detachment also helps prevent falls. In addition, since lean meat does not easily protrude from the upper end when sitting, and it looks refreshing, it is expected that the silhouette will be less affected when wearing clothing that fits the body.
