Description

  The present invention relates to a swimsuit that achieves body shape correction, posture retention, and mobility, and particularly to a swimsuit for competition.

  Swimming competition is an event that competes to swim faster than a specified distance. The swimming speed is expected to increase by increasing the propulsive force and decreasing the resistance.

  Regarding the reduction of resistance, the density of water is higher than in air, and the influence of resistance in water is large. Therefore, it is required to increase the landing pressure of the swimsuit, correct the body shape, reduce the projected area on the vertical plane with respect to the traveling direction, reduce the unevenness, and reduce the water resistance. In addition, it is clear that the posture during the swimming operation also affects the projected area, and it is required to maintain the stream posture.

  In order to obtain a propulsive force, it is required to perform a stroke operation and a kick operation to scrape more water, and a swimmer must perform a swimming technique with less resistance.

  For these reasons, swimsuits, particularly swimsuits for swimming, are required to have body shape correction, posture retention, and mobility in strokes and kick operations.

  In order to maximize body shape correction, conventional swimsuits are designed to apply a large pressure of 4 kPa or more. In order to apply a large pressure, it is necessary to reduce the stretchability of the fabric. Then, the wearing pressure accompanying the elongation at the time of wearing compresses the body and reduces the projected area. However, a material with low stretchability hinders stream posture maintenance and mobility.

  In order to obtain the maximum propulsive force, the shoulder joint is moved to the full range of motion when swimming. A large skin stretch occurs on the body side with the movement of the shoulder joint, but a general swimming swimsuit does not follow the skin stretch so much. Due to the low stretchability of the fabric of the corresponding part, it leads to the restriction of movement. The same can be seen when the upper arm is raised while maintaining the streamline posture.

  Patent Document 1 proposes a swimsuit that allows a wearer to easily perform a predetermined operation. As shown in FIG. 14, this swimsuit is formed so as to be in close contact with the wearer's body when worn, and has an upper body part 110 and a lower body part 140 having predetermined elasticity, and the wearer's body. It is arranged in a region corresponding to the vicinity of the ribs (side body part 121) and a region corresponding to the vicinity of the inner side of the thigh from the groin part of the wearer (inner crotch part 122), and expands and contracts more than the upper body part 110 and the lower body part 140 And a weak tightening portion 120 having high properties.

  In the swimsuit described in Patent Document 1, a material having higher elasticity than the upper body part 110 and the lower body part 140 is disposed in an area corresponding to the vicinity of the ribs and an area corresponding to the vicinity of the inside of the thigh from the groin. Thus, it is easy to perform an operation of turning an arm or moving a foot in a swimming operation.

  Further, Patent Document 2 proposes a swimsuit that corresponds to a region where the skin stretches greatly due to a swimming action and leaves a trunk portion made of stretchable fabric without a panel below the heel.

  In the swimsuit described in Patent Document 1 described above, it is estimated that a region where the skin stretches due to the swimming motion is large as a region corresponding to the vicinity of the ribs, and a region corresponding to the inside of the thigh from the groin, so that the swimming motion is not hindered. In addition, it is described that a highly stretchable material is disposed at the same site, and the stretch rate when stretched with an arbitrary force is greater than the other sites with respect to the stretch rate in the length direction. However, in order to obtain body correction, it is necessary to apply a large pressure. The wearing pressure is caused by the elongation at the time of wearing and the stretchability of the material. If the stretchability is increased, the wearing pressure is inevitably reduced, and the body shape correction is impaired.

  Moreover, the swimsuit shown in Patent Document 2 is configured to leave a trunk portion made of stretchable fabric without a panel below the heel, which corresponds to a region where the skin stretches greatly during swimming. However, in this swimsuit, a highly elastic panel is arranged on the side of the side where the skin stretch increases with the swimming action, hindering mobility.

  Hereinafter, a swimsuit according to an embodiment of the present invention will be described in detail with reference to the drawings. The swimsuit of this embodiment is a swimsuit for competitions, for example, and has a region covering the upper body 10, the shoulder 11, the buttocks 12, and the crotch 13 that are in close contact with the body surface, as shown in FIGS. In this swimsuit, regions are defined, and the respective stretchability is set in each region.

  First, the definition of each area will be described. As shown in FIG. 1, the contour of the front of the body in the longitudinal cross section in the front-rear direction of the body passing through the anterior axillary point 41 is the contour of the front surface of the body in the longitudinal cross-section in the longitudinal direction of the body passing through the anterior axillary line 44. The line is designated the axillary line 45.

  As shown in FIG. 1 and FIG. 2, the area covering the area surrounded by the left and right anterior axillary lines 44, 44 on the front surface of the body when standing still is the first area 1, and the anterior axillary line on the body side when standing still 44 and the rear axillary line 45, the region covering the range having the lower end as the waist line is surrounded by the second region 2, the front axillary line 44 and the rear axillary line 45 on the body side when standing still, and the upper end at the waist A region covering the line 46 and a range where the lower end is the upper end of the iliac crest is defined as a third region 3.

  As shown in FIG. 3, a portion in contact with the second region 2 in the first region 1 is defined as a first boundary 47, and a portion in contact with the third region in the first region is defined as a second boundary 48. Here, the widths of the boundaries 47 and 48 are each 1/3 or less of the first region 1.

  And, as shown in FIG. 3, the present invention sets the stretchability in the body long axis direction of the fabric and the stretchability in the body circumferential direction of the fabric to predetermined values, respectively, in each region and boundary described above. It achieves body shape correction, posture retention, and mobility.

  Here, the stretchability of the fabric of the first region 1 in the body long axis direction is S1, the stretchability of the fabric of the first region 1 in the body peripheral direction is S2, and the stretch of the fabric of the second region 2 is the body long axis direction. The stretchability of the fabric of the second region 2 is S4, the stretchability of the fabric of the second region 2 in the body circumferential direction is S4, the stretchability of the fabric of the third region 3 in the body long axis direction is S5, and the fabric of the fabric of the third region 3 is The stretchability in the circumferential direction is S6, the stretchability in the body long axis direction of the fabric of the first boundary 47 is S7, the stretchability of the fabric in the body boundary direction of the first boundary 47 is S8, and the fabric of the second boundary 48 is S9 is the stretchability in the body long axis direction, and S10 is the stretchability in the body peripheral direction of the second boundary 48.

  By the way, the first region 1, the second region 2, and the third region 3 described above correspond to a case where a person with a standard body shape wears the corresponding size of the swimsuit of this embodiment in close contact with the body surface. The location is specified. In the swimsuit that is not worn by the swimmer shown in FIG. 4, it can be defined as follows.

  The width of the front body 10 is 40% of the circumference of the waistline 46 centered on the front center line of the swimsuit (in the upper body, the width of the waistline 46 is centered on the side line 10a of the swimsuit. The area covering the area with the crotch at the lower end is the first area 1, and the upper body is centered on the side line 10a of the swimsuit, and the width is 10% of the waistline circumference, The area covering the range where the lower end is the waistline 46 of the swimsuit is the second area 2, the swimline waistline 46a is the center, the upper end is the waistline 46 of the swimsuit, the lower end is the middle hip line 46m, and the width is the circumference of the waistline A region covering a range of 10% of the third region 3 is a third region 3. Further, the first boundary 47 is a region in contact with the second region 2 in the first region 1, and each width is 1/3 or less of the first region 1. The second boundary 48 is a region in contact with the third region 3 in the first region 1, and each width is 1/3 or less of the first region 1.

  Next, the reason why the first region 1, the second region 2, and the third region 3 are specified as described above will be described. FIGS. 5A to 5C are explanatory diagrams showing the distribution of skin elongation during a stream posture in nudity. FIG. 5 (a) is an explanatory view showing the distribution of skin elongation on the front side of the body, FIG. 5 (b) is an explanatory view showing the distribution of skin extension on the side of the body, and FIG. 5 (c) is the upper limb on the front side of the body. It is explanatory drawing which shows distribution of the skin elongation at the time of raising. Moreover, the arrow has shown the direction where skin extends.

  As shown in FIGS. 5 (a) and 5 (b), in the vicinity of the center of the front of the body (first region 1), when the standing position is 0%, the skin elongation is less than 40%. It plays a role as a core in maintaining the stream posture. On the other hand, with the movement of the shoulder joint, a very large skin elongation of 80% or more occurs above the waistline on the body side (second region 2). Furthermore, in the third region 3 from the waist on the body side to the iliac crest, moderate skin elongation of 40 to 80% occurs.

  It is considered that body shape correction, posture retention, and mobility can be realized by setting the elasticity of the swimsuit so as to correspond to the elongation amount and the direction of the elongation distribution of the skin. Therefore, the first region 1 which is a region where the skin elongation is not so large is a region covering the range surrounded by the left and right anterior axillary lines 44 and 44 when standing still on the front surface of the body as described above. In the swimsuit itself, the front is the front center line of the swimsuit, and the width is 40% of the circumference of the waistline, and the area covering the inseam is the lower end.

  The second region 2, which is a region where the skin stretch is very large, is a region that is surrounded on the body side by the anterior axillary line 44 and the rear axillary line 45 when standing still and covers the range with the waist line 46 as the lower end. . In the swimsuit itself, the width is a region that covers 10% of the circumference of the waistline, with the waistline 46 of the swimsuit at the lower end centered on the side line 10a of the swimsuit.

  The third region 3, which is a region where the skin stretch is slightly large, is surrounded by the anterior and posterior axillary lines when standing still on the body side, with the waistline as the upper end and the iliac crest as the lower end The area that covers In the swimsuit itself, the width is an area covering 10% of the circumference of the waistline with the waistline 46 as the upper end and the middle hip line 46m as the lower end with the side line 10a of the swimsuit as the center. The middle hip line 46m is defined by a center line between the waist line and the hip line, and indicates a line passing near the upper anterior iliac spine when worn.

  Next, the values of the stretchability in the body long axis direction of the fabric and the stretchability in the body circumferential direction of the fabric in each region will be described in detail below. Here, in this specification, “the stretchability of the fabric in each region” means “the stretchability of the fabric in each region”. That is, even when the stretchability is partially different in each region, the stretchability is evaluated by looking at each region as a whole, instead of evaluating the stretchability by focusing on only a part. Further, the “stretchability of the fabric in each region” can be appropriately adjusted by various processes such as a method of knitting and weaving the yarn constituting the fabric, overlaying of the fabric, resin processing, and the like.

The stretchability of the fabric in the first region 1 and the stretchability of the fabric in the second region 2 are set to the following (a) to (c).
(A) The stretchability S3 in the body long axis direction of the fabric in the second region 2 is higher than the stretchability S1 in the body long axis direction of the fabric in the first region 1 (S3> S1).
(B) The stretchability S3 in the body long axis direction of the fabric in the second region 2 is higher than the stretchability S4 in the body circumferential direction of the fabric in the second region 2 (S3> S4),
(C) The stretchability S3 in the body long axis direction of the fabric in the second region 2 is higher than the stretchability S2 in the body circumferential direction of the fabric in the first region 1 (S3> S2).
The difference in stretchability described above is preferably 10% or more.

  As shown in FIG. 6, in the first region 1 and the second region 2, the stretchability in the body peripheral direction, S2 and S4 are set lower than the stretchability S3 in the body long axis direction. By reducing the stretchability S2 and S4 in the body peripheral direction in the first region 1 and the second region 2, a large pressure is generated as the fabric stretches during wearing, and the body shape correction of the easily protruding chest is improved. To do. As a result, the projected area is reduced, the resistance is reduced, and the swimming speed is not impaired.

  Further, the stretchability S1 in the body long axis direction in the first region 1 is set lower than the stretchability S3 in the body long axis direction in the second region 2. By reducing the stretchability S1 in the body major axis direction in the first region 1, the body core portion is stabilized and the posture retention is improved in maintaining the stream posture.

  Furthermore, the stretchability S3 in the body long axis direction of the second region 2 is set higher than the stretchability S1 in the body long axis direction of the first region 1. By increasing the stretchability S3 in the body long axis direction in the second region 2, the fabric follows the skin elongation during the stroke operation, and in particular, the glide operation (elongation) during the stroke is not hindered. The glide operation is an operation in which the upper limb is stretched in water and the tip of the body is brought close to the stream line, and the resistance to the propulsive force generated by the kick or the pull operation of the opposite upper limb is minimized. In addition, the previous water can be pulled. On the other hand, when the glide operation is insufficient during kicking or pulling and the stream line breaks, the resistance increases and the propulsion force is lost.

  Further, the stretchability S1 in the body long axis direction of the fabric in the first region 1 may be set higher than the stretchability S4 in the body circumferential direction of the fabric in the second region 2 (S1> S4). Further, the stretchability S1 in the body long axis direction of the fabric in the first region 1 may be set higher than the stretchability S6 in the body circumferential direction of the fabric in the third region 3 (S1> S6).

  As described above, by making the stretchability S1 in the body long axis direction of the first region 1 higher than the stretchability in the body peripheral direction of the second region 2 or the third region 3 than S4 and S6, Stretching in the body long axis direction of the first region 1 (skin elongation at the center of the chest in FIG. 5C), which occurs when the trunk stands upright to maintain the stream posture, can be relaxed, and posture retention Will improve.

  Further, the stretchability S2 and S4 in the body peripheral direction in the first region 1 and the second region 2 is more than the stretchability S1 and S3 in the body long axis direction in the first region 1 and the second region 2, By being low, the wearer can easily feel the pressure applied to the center of the trunk rather than being stretched in the longitudinal direction of the body accompanying the movement, and can be more aware of the body axis, thereby improving posture retention.

  Further, the stretchability S4 of the fabric in the second region 2 in the body peripheral direction may be set to be equal to the stretchability S2 of the fabric in the body region of the first region 1 (S2≈S4).

  As described above, by having the same low elasticity in the peripheral direction of the body in the first region 1 and the second region 2, uniform contact pressure in the central direction of the trunk is applied to any part in the peripheral direction, The body axis can be further stabilized, and the posture retention is improved.

Further, the stretchability of the fabric in the first region 1 and the stretchability of the fabric in the third region 3 may be set to the following (d) to (f).
(D) The stretchability S5 in the body long axis direction of the fabric in the third region 3 is higher than the stretchability S1 in the body long axis direction of the fabric covering the first region 1 (S5> S1).
(E) The stretchability S5 in the body long axis direction of the fabric in the third region 3 is higher than the stretchability S6 in the body peripheral direction of the fabric covering the third region 3 (S5> S6).
(F) The stretchability S5 in the body long axis direction of the fabric in the third region 3 is higher than the stretchability S2 in the body peripheral direction of the fabric covering the first region 1 (S5> S2).

  As shown in FIG. 6, in the first region 1, the second region 2, and the third region 3, the stretchability S2, S4, S6 in the body circumferential direction and the stretchability S3, S5 in the body long axis direction are used. Make it lower. By reducing the stretchability S2, S4, and S6 in the body peripheral direction in the first region 1, the second region 2, and the third region 3, a large pressure is generated as the fabric is stretched and worn out. Easy to correct body shape of the lower abdomen. As a result, the projected area is reduced, the resistance is reduced, and the swimming speed is not impaired. Furthermore, it is considered that the pressure applied to the center in the lower abdominal position contributes to increasing the intraabdominal pressure. The increase in intra-abdominal pressure contributes to the standing of the spine, and can be expected to improve the posture retention of the stream posture.

  Further, the stretchability S1 in the body long axis direction in the first region 1 is set lower than the stretchability S5 in the body long axis direction in the third region 3. By reducing the stretchability S1 in the body major axis direction in the first region 1, the body core portion is stabilized and the posture retention is improved in maintaining the stream posture.

  Further, the stretchability S5 in the body long axis direction in the third region 3 is set higher than the stretchability S1 in the body long axis direction of the first region 1. By increasing the stretchability S5 in the body long axis direction in the third region 3, the fabric follows the skin elongation during the stroke operation, and in particular, the glide operation (elongation) during the stroke is not hindered.

Further, the stretchability S6 in the body circumferential direction of the fabric in the third region 3 may be set equal to the stretchability S2 in the body circumferential direction of the fabric in the first region 1 (S2≈S6).
As described above, by having the same low elasticity in the body peripheral direction in the first region 1 and the third region 3, a uniform contact pressure in the central direction of the trunk is applied to any part in the peripheral direction, The body axis can be further stabilized, and the posture retention is further improved.

The first region 1 has a first boundary 47 in contact with the second region 2, the stretchability of the fabric of the first boundary 47, and the fabric of the first region 1 and the fabric of the second region 2. The stretchability is preferably set to the following (g) and (h).
(G) The stretchability S7 in the body long axis direction of the fabric of the first boundary 47 is a value between the stretchability S1 and S3 in the long axis direction of the first region 1 and the second region 2 (S1 <S7). <S3),
(H) The stretchability S8 in the circumferential direction of the fabric of the first boundary 47 is equivalent to at least one of the stretchability S2 and S4 in the circumferential direction of the first region 1 and the second region 2 (S2 = S8 = S4), or a value between the stretchability S2 and S4 in the circumferential direction of the first region 1 and the second region 2 (S2 (S4) <S8 <S4 (S2)).

  The fabric of the first boundary 47 may be a single stretch, but may be configured to have a gradation as follows.

  The stretchability S7 in the body long axis direction of the fabric of the first boundary 47 is a value close to the stretchability S1 in the long axis direction of the first region 1 toward the boundary line with the second region 2 in the circumferential direction. What is necessary is just to set so that it may approach the elastic property S3 of the major axis direction of the 2nd area | region 2, and may change sequentially.

The first region 1 has a second boundary 48 in contact with the third region 3,
The stretchability of the fabric of the second boundary 48 and the stretchability of the fabric of the first region 1 and the fabric of the third region 3 are preferably set to the following (i) and (j).
(I) The stretchability S9 in the body long axis direction of the fabric of the second boundary 48 is a value between the stretchability S1 and S5 in the long axis direction of the first region 1 and the third region 3 (S1 <S9). <S5),
(J) The stretchability S10 in the body circumferential direction of the fabric of the second boundary 48 is equivalent to at least one of the stretchability S2 and S6 in the circumferential direction of the first region and the third region (S2 = S10 = S6). Or a value between the stretchability S2 and S6 in the circumferential direction of the first region 1 and the third region 3 (S2 (S6) <S10 <S6 (S2)).

  The fabric of the second boundary 48 may be a single stretch, but may be configured to have a gradation as follows.

  The stretchability S9 in the body long axis direction of the fabric of the second boundary 48 is from a value close to the stretchability S1 in the long axis direction of the first region 1 toward the boundary line with the third region 3 in the circumferential direction. The third region 3 gradually changes as it approaches the stretchability S5 in the major axis direction.

  As described above, the expansion and contraction in the body long axis direction of the swimsuit corresponding to the boundary between the first region 1 and the second region 2 and the first region 1 and the third region 3 having different stretchability in the body long axis direction. By setting the sex to an intermediate value in the body long axis direction of both regions, the pulling and glide motions, which are the movements of the upper limbs, are not hindered, and the pulling motion and the glide motion that are the motions of the upper limbs are prevented. In addition, stress concentration that causes breakage or the like occurs at the boundary having a large difference in elasticity, but the stress concentration can be prevented because the elasticity in the boundary is an intermediate value. The boundary may be a single stretch, but the gradient S9 gradually changes from the stretch S1 to the stretch S5 toward the boundary with the third region 3 in the circumferential direction. It is preferable.

  Next, the details of stretchability will be described. In the swimsuit (example) of the embodiment of the present invention shown in FIG. 6, the material characteristics of the portions corresponding to the second region 2 and the third region 3 are indicated by thin line arrows in the body long axis direction. The material property of the portion corresponding to the first region 1 having high stretchability is lower than that of the second region 2 and the third region 3. On the other hand, in the peripheral direction between the material characteristics of the portion corresponding to the first region 1 and the material properties of the portions corresponding to the second region 2 and the third region 3, as shown by the thick arrows, low stretchability Both are equivalent.

  S1 to S6 in FIG. 6 indicate the stretchability in the body long axis direction and the peripheral direction of each region. This stretchability was calculated by performing a tensile test using an autograph universal testing machine (manufactured by Shimadzu Corporation). The conditions were 5 cm × 20 cm test pieces, 10 cm between chucks, a pulling speed of 20 cm / min, and the number of trials was 3 trials for each stretchability. The results are shown in FIG.

  As a result of measuring the load at 40% elongation, this example shows that the 40% elongation load of the stretches S3 and S5 in the body long axis direction of the second region 2 and the third region 3 is the first region. It was 19% smaller than the stretchability S1 in the major axis direction of 1. It shows that elasticity is so high that the load at the time of arbitrary expansion | extension is small. The stretchability S3 and S5 in the major axis direction of the second region 2 and the third region 3 was 38% smaller than the stretchability S4 and S6 in the circumferential direction of the second region 2 and the third region 3. .

  Further, the stretchability S4 and S6 in the peripheral direction of the second region 2 and the third region 3 was 29% larger than the stretchability S1 in the major axis direction of the first region 1.

  The stretchability S4 and S6 in the circumferential direction of the second region 2 and the third region 3 is substantially equal to the stretchability S2 in the circumferential direction of the first region 1, and the difference is 3% or less. Usually, in the manufacture of dough, the basis weight is not uniform throughout the dough, but efforts are made to keep it below 10%. Therefore, a difference of less than ± 10% has the same stretchability, and if there is a characteristic difference of more than that, it has a different stretchability, and the effect of the present invention can be obtained.

Next, verification of the effect according to the embodiment of the present invention will be described.
There are the following three conditions. Nude, comparative swimsuits and example swimsuits. The comparative swimsuit uses the same material in all areas.
The measurement items are stretchability, skin and fabric elongation, pressure, and perimeter.

  FIG. 7 shows the fabric stretchability measured as described above. The smaller the value, the higher the elasticity. The relationship between the stretchability S3 in the major axis direction and the stretchability S1 was S3 = S1 in the comparative swimsuit, whereas S3> S1 in the swimsuit of this example. The magnitude relationship between the stretchability S3 and the stretchability S4 in the circumferential direction was reversed between the comparative swimsuit and the swimsuit of this example, and the stretchability S4 was lowered in the swimsuit of the example. Elasticity S2 and elasticity S4 were equivalent. In addition, the values of the stretch S1 and the stretch S3 of the swimsuit of this embodiment are significantly lower than the values of the stretch S1 and the stretch S3 of the comparative swimsuit. In the comparative swimsuit, the stretchability S1, S3, S7 in the major axis direction shows the same stretchability, and the stretchability S2, S6, S10 in the peripheral direction shows the same stretchability.

  The skin and fabric elongation was calculated from the coordinate values obtained by measuring the 3D marker coordinates when retroreflective markers were applied to the body in a grid pattern at a single interval, and the streamline posture and backstroke simulation were performed. Is. Skin and fabric elongation indicates lattice deformation. FIG. 8 shows the fabric elongation distribution in the swimsuit of the embodiment when the streamline posture is maintained. Arrows indicate the direction of skin and fabric elongation. The part surrounded by area A in (a) was calculated. The test subject was one woman.

  FIG. 9 shows in detail the skin and fabric elongation distribution of each condition for the region B covered with the swimsuit in the second region 2. The maximum elongation under nude conditions was 100%. Compared to (n), which shows the fabric elongation of the swimsuit for comparison, compared to (n), which shows the skin elongation under the nudity condition, the area showing the fabric elongation of 40% or more seen under the nudity condition is reduced, and the fabric is in operation. It can be seen that does not follow. On the other hand, in the swimsuit of this example, an area of 40% or more indicated by dark hatching was observed, and the area of 30% or more increased as a whole. From this, it can be seen that in this embodiment, the fabric follows the movement more. It shows that the stream posture retention was improved. Further, in the backstroke simulation operation shown in FIG. 10, it was confirmed that the swimsuit of this example increased in the fabric elongation and followed the operation more than the comparative swimsuit.

  The result measured about the adhesion pressure is shown. The test subjects were two women, and the results of measuring the pressure in front of each abdomen, flank and chest are shown in FIG. As shown in FIG. 11, the comparative swimsuit and the swimsuit of the example were equivalent in the pressure in front of the stomach, the flank, and the chest. Each landing pressure contributes to the perimeter of each site and is related to the projected area.

  The measurement result about the perimeter is shown. The test subjects were two women, and as shown in FIG. 12, the length of the circumference W in the bust circumference B and the lower abdominal circumference did not increase as compared with the comparative swimsuit. The perimeter of each site is related to the projected area. In this example, it was confirmed that the mobility could be improved without affecting the projected area.

  The swimsuit of this example used in the above experiment had elasticity as shown in FIG. The material of each region of the present example having such stretch characteristics was as follows. The level of elasticity was given by the density difference. That is, the density in the swimsuit peripheral direction is the same for both the first region 1 and the second region 2, and the density in the major axis direction is slightly higher in the first region 1 than in the second region 2 to expand and contract. High and low nature was given. The higher the density, the greater the number of spandex, and the higher the stress during elongation and recovery. However, if the density difference is too large, problems such as weaving yarn misalignment (strain) occur. Therefore, it is preferable to set the density within 10 / inch, and this time, the difference is 4 / inch.

  The form of the swimsuit of the present invention is basically a one-piece swimsuit for men and women with a shoulder strap, and may be a type without a leg.

  The material of each region is made of 2WAY stretch knitted fabric, woven fabric, or non-woven fabric. The level of elasticity and anisotropy can be provided depending on the type of yarn in each direction, the thickness of the yarn, the presence or absence of twisting, the density of the structure, and the like.

  Although it is preferable to reduce the resistance by forming the swimsuit upper body with a single material by the above method or the like, it is also possible to combine materials with different stretch characteristics by sewing or seam tape. The sewing part or the seam tape is desirably stretchable. It is desirable that the second region 2 and the third region 3 have no sewing portion or seam tape. Moreover, although the material in the 1st area | region 1 may combine a some raw material on a design, the main fabric has said elastic property. In addition, the shape of the sewing line (the line between the first region and the second region, the line between the first region and the third region, etc.) is curved, wavy or zigzag in design. It may be linear.

  Further, the first region 1 may be reinforced by post-processing such as rubber printing or urethane panel. Moreover, you may reinforce by overlapping dough. In this case, different materials may be stacked.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims for patent.
