Description

bra

technical field

The present invention relates to a bra capable of suppressing shaking of breasts when the bra is worn. More specifically, the present invention relates to a bra that does not spoil the aesthetics, has the effect of suppressing the shaking of the breasts when performing actions in the worn state, that is, has vibration damping properties, and has moderate wearing pressure and has the function of wearing. comfortability.

Background technique

One of the main purposes of a bra is to adjust the shape of the breast more beautifully. However, it is also one of the biggest functions of the bra to suppress the shaking of the breast during exercise. However, in most cases, even wearing a bra, the breasts will still vibrate more violently when walking or running. In particular, in the case of a large breast size, the above-mentioned shaking becomes very severe, causing discomfort and burden to the wearer, and not only that, but also causes the breast to sag. As a method for reducing the above-mentioned swaying, it is effective to wear a bra having a strong wearing pressure, but this method leads to a marked deterioration in wearing comfort. Furthermore, there has been a growing problem that especially during sports, the shaking of the breasts becomes more severe, which hinders the movement of the wearer and imposes a burden on the wearer. Therefore, many sports bras have been developed as bras for reducing the movement of breasts during exercise (Patent Document 1 and Patent Document 2). However, in the case of sports bras, in order to suppress the shaking of the breasts during exercise, most of them are designed in such a way that the coverage area is made large and the cleavage is blocked. Therefore, most of them lack aesthetics and are not popular for daily use.

Therefore, in consideration of daily use, it is desirable to develop a bra that exposes the cleavage to a large extent, ensures aesthetics, and in this state reduces the shaking of the breasts during daily light exercises and wears it. The pressure is also moderate.

Patent Document 3 describes a bra that has: a pair of cups; a connecting portion that connects the front center sides of the cups to each other; wings; The cup is connected to the wings, wherein the cup has at least a pad with a high stress portion of the pad extending along an upper edge of the pad or along a lower edge of the pad Stretching, or extending along both the upper edge of the pad and the lower edge of the pad, the ratio S2/S1 of the stretching stress S2 of the high stress portion of the pad to the stretching stress S1 of the areola corresponding portion of the pad is 2/1 to 80 /1.

In the technique described in Patent Document 3, the flap portion is arranged on the bra main body over the entire region from the cup portion to a part of the wing portion. By arranging flaps made of a gray cloth with a tensile stress different from that of the bra main body fabric, it is possible to utilize the difference in tensile stress between the bra main body fabric and the flap fabric in a state where the bra is worn. A force that pulls the joint portion of the cup portion with the flap portion toward the wing portion acts, and a vibration damping effect can be exhibited.

In the above-mentioned bra, the effects of the flaps allow the cleavage to be largely exposed, but it is possible to suppress the shaking of the breasts during movement without impairing the comfort. However, although the subjective evaluation of the shakiness and comfort of this bra in the wearing state is improved compared with ordinary bras, and the shakiness value is also lowered, there are also the following cases : Depending on the wearer, some people may experience some discomfort in terms of comfort.

Contents of the invention

The problem to be solved by the invention

Therefore, the problem to be solved by the present invention is to provide a bra that has the effect of reducing the shaking of the breast during exercise, that is, is excellent in shock absorption, and preferably provides a bra that is excellent in aesthetics and comfort in addition to excellent shock absorption. bra.

solutions to problems

The present inventors conducted measurements using an accelerometer and found that in products that suppress the shaking of the entire breast like the bra disclosed in Patent Document 3, there is actually a situation in which the breasts shake slightly in three-dimensional directions within the cup. According to the acceleration, the product that can suppress the shaking of the breast as a whole can suppress the violent shaking of the breast, but the acceleration caused by the slight vibration is generated in all directions, and the breast will always be impacted by the acceleration. The above can be considered to be the reason why the swaying of the breasts in the state of wearing the bra can be restrained, but the wearer may feel uncomfortable. Therefore, it is considered that it is necessary to alleviate the occurrence of this acceleration in order to further improve wearing comfort.

Furthermore, it has also been found that, depending on the wearer, the wearer may feel uncomfortable with respect to the cup portion. That is, it has been found that when the flap portion is provided as the vibration damping portion, the tensile stress difference between the flap portion provided on the cup portion and the bra main body fabric, especially the wing portion, is used to make the vibration from the joint portion of the flap portion The force pulling toward the wings acts to exert a vibration damping effect, so applying a force greater than that of the bra main fabric to the cup portion may cause discomfort to the breasts. In particular, for bras with metal wires in the lower part of the cups for adjusting the shape of the breasts, the wearer may feel uncomfortable feeling that the wires are caught in the lower part of the breasts. Therefore, it is considered that in order to further improve the wearing comfort, it is necessary to reduce the uncomfortable feeling caused by the metal wire getting caught in the skin.

In order to solve the above-mentioned problems, the present inventors conducted intensive research and repeated experiments, and found that a bra having an opening and a specific vibration-reducing part can achieve a predetermined value by setting the physical properties of the connecting part connecting the cup parts to a predetermined value. , so that the acceleration during movement can be suppressed without increasing the wearing pressure. Furthermore, it was found that a bra having a flap portion as a vibration damping portion can be obtained by setting the physical properties of the flap portion to a specific value, and by making the physical properties of the bra main body fabric, particularly the wing portion fabric, and the flap portion fabric be specific.

Detailed ways

Next, examples of typical embodiments of the present invention will be described in detail.

One embodiment of the present invention provides a bra, which has: a pair of cup parts; a connecting part, which connects the front center side parts of the cup parts; Adjacent; and the shoulder girdle, the end of which is connected to the pair of cups and the wings, and the extension test is carried out to make the connecting part repeatedly stretched by 10% in the lateral direction, and the connecting part is stretched for the third time. The tensile stress is 10N to 30N, and the bra has a specific shock absorbing part. By making the connection part and the specific vibration damping part exist at the same time, it is possible to obtain a more obvious vibration reduction effect than the case where only the connection part exists.

With reference to Fig. 1, the bra 100 of one embodiment of the present invention has: a pair of cup parts 102 (in the accompanying drawing, one cup part in a pair of cup parts is indicated by the area surrounded by dotted lines); The front center side parts of the cup part are connected together; and the wing part 103 (which is arranged on the underarm side part of the cup part 102 (ie, the underarm side of the wearer)). It is also possible that the connecting portion 101 is, for example, a lower side band, which extends along the lower edge of the cup portion 102 to form the lower end of the bra. The wings 103 extend towards the back of the wearer. The wings 103 can have a base and a lower edge (eg, a band). Each member is made of cloth. The bra also has shoulder straps 110 whose ends are connected to the wings 103 and the pair of cups 102 .

For the bra of the present invention, it is assumed that the cups accommodate the wearer's breasts. Furthermore, it is assumed that the connecting portion connects the front center side portions of the cup portions to each other. Furthermore, it is assumed that the shoulder straps extend from the front of the chest, go around the left and right shoulders of the wearer, and then connect to the wings on the back of the wearer.

In the present invention, "wearer's side" is intended to mean the inner side of the bra (that is, the side where the cups are in a concave shape), and "outer side" is intended to mean the side opposite to the above-mentioned wearer's side.

In the present invention, the "lateral direction" (for example, the lateral direction of the connecting portion) mentioned with respect to the bra is intended to refer to the arrangement direction of the two cups, specifically, the position at which the corresponding positions of the areolas of the two cups are farthest from each other. The extension direction of the straight line connecting the corresponding positions of the two areolas when placing the bra. In the present invention, the "longitudinal" of the bra is intended to mean the direction perpendicular to the above-mentioned transverse direction, and corresponds to the up and down direction of the wearer's body.

In the present invention, the "areola corresponding position" is intended to mean a position corresponding to the areola of the wearer when the bra is worn (ie, a position corresponding to the nipple of the wearer). The corresponding position of the areola is the top of the raised shape (convex shape) of the cup. In the present invention, the "front centerline" and "back centerline" of the bra are the lines that pass through the midpoints of the line segments connecting the corresponding positions of the two areolas respectively and extend along the longitudinal direction of the bra. The front centerline is located at the front of the chest. The line at the center of the back is the line at the wings.

In the present invention, the circumference of a bra is intended to mean the shortest length of a line drawn on the body of the bra in such a way that it starts from the front center line, passes through the center of the back and then returns to the front center line (however, in the case of a bra In the case of having a length adjustment mechanism (such as the length adjustment mechanism 106 in FIG. 4 described later), the circumference of the bra refers to the value when the circumference is adjusted to the maximum by the length adjustment mechanism).

In the present invention, the connecting portion 101 connects the front center side portions of the cup portion to each other, and carries out a stretching test in which the connecting portion 101 is repeatedly stretched by 10% in the lateral direction, and the stretching stress of the connecting portion 101 when stretching for the third time is 10N ~ 30N. And, for the bra of the present invention, by combining one or more specific damping parts on the basis of the connecting part, it is possible to suppress the subtle vibration of the breasts during the movement, reduce the load applied to the body during the movement, and can It has high comfort.

Typically, the assumption is that the cups contain the wearer's breasts. But in fact, in the cup, the breasts are not completely along the cup, and the breasts are not fixed by the cup. Therefore, it is considered that when the breast shakes during the movement, the breast vibrates slightly in the cup. Regarding this fine vibration, even if the breast is not perceived to be shaking from the appearance, this fine vibration still occurs in directions such as the X direction, the Y direction, and the Z direction. When the bra is worn, the bra is stretched in the lateral direction. At this time, a lateral stretching force starting from the stretching of the wings acts to stretch the fabric of the cup connecting portion. Therefore, it is considered that the connection part is separated from the skin, and a gap is formed between the connection part and the skin. It can be considered that due to the gap, there is an area near the front of the cup where the cup and the breast are not provided, that is, a region where the breast may escape, thereby reducing the fixing ability of the cup. Therefore, it is presumed that this phenomenon causes the wearer to feel shaking and discomfort even though the breasts are not visibly shaking violently when wearing a bra.

A stretching test was carried out in which the connecting portion was repeatedly stretched by 10% in the lateral direction. The stretching stress of the connecting portion was 10N to 30N when stretched for the third time, which is advantageous in suppressing the shaking of the breast. The aforementioned tensile stress is preferably 15N to 25N. When the above-mentioned tensile stress is 10N or more, the connecting part becomes difficult to stretch, and the connecting part becomes a fixed point, so that the connecting part does not separate from the skin, and the breast can be fixed in the area from the front of the cup to the side of the cup, and the fine vibration of the breast can be suppressed . Moreover, when the above-mentioned stretching stress is 30N or less, the gray fabric will not feel too stiff when wearing a bra, so the shaking of the breasts can be suppressed without impairing the comfort.

In addition, the transverse stretching stress specifically measures the stress when each site is stretched in the horizontal direction (for example, the extending direction of a straight line L1 in FIG. 3 described later). Unless otherwise specified, the elongation and tensile stress in the present invention are values measured based on the strip method tensile test in JIS L1096.8.12.1 A method.

In addition, unless otherwise specified, the physical property values mentioned in the present invention may be measured by holding the end of each part of the bra (for example, the connecting part), or may be measured from each part first. Cutting out a piece of fabric and then measuring the fabric means that the physical property value measured by any of the above methods may be used as the physical property value of the present invention.

The connecting portion is not particularly limited as long as it is a fabric that satisfies the above-mentioned requirements, but examples include fabrics composed of cotton woven fabrics, polyester woven/knitted fabrics, and woven fabrics made of polyamide materials. Knitted fabrics containing spandex yarn fibers such as knitted fabrics, knitted gray fabrics with elastic mesh, and bidirectional knitted gray fabrics.

By arranging the aileron part, setting the high stress part on the upper edge of the cup and/or the high stress part on the lower edge of the cup, and setting the vibration damping part on the shoulder part, it is also possible to suppress the relatively severe shaking perceived from the appearance. The effect of pulling the breasts toward the trunk by the connecting portion with specific physical properties complements each other, thereby firmly adhering the cup and the breasts, and further suppressing slight swaying of the breasts.

In a particular embodiment, the bra has an upper edge high stress portion (eg, upper edge high stress portion 104 in FIG. 1 ) extending along the upper edge of the cup.

In certain embodiments, the bra has a lower edge high stress portion (eg, lower edge high stress portion 105 in FIG. 1 ) extending along the lower edge of the cup.

With particular reference to Figure 2, in a particular embodiment, the bra has flap portions 109 as shock absorbing portions. When the bra is worn, the gray fabric of the flap part is stretched in the range from the cup part to the wing part, thereby, the breast can be drawn toward the direction of the human body's torso, thereby improving the closeness between the cup and the breast, and making the cup The effect of integrating with the breast is excellent, and it has the effect of preventing the breast from leaving the cup when performing movements. Thereby, it is possible to suppress the relatively violent shaking of the breast that is perceived externally during the movement.

The flap portion 109 is arranged on the bra main body over the entire region from a part of the cup portion 102 to a part of the wing portion 103 . A typical flap portion 109 can be composed of one piece of fabric or a plurality of pieces of fabric arranged over the entire area from the armpit edge of the cup portion 102 to the wing portion 103 . The flaps 109 are not formed integrally with the bra body in the cup portion 102 and the wing 103, but are formed by being overlaid on the bra body with fabric independent of the bra body.

The flap portion 109 and the bra body typically have two joints described below.

As for the first joint part, the bra 100 is arranged such that the line segment I connecting the areola corresponding part H of each cup part 102 and the back center C of the corresponding wing part is the longest, and it is specified to have a line segment corresponding to the line segment. In this case, 0% to 25%, preferably 5%, of the line segment I on the line segment I, starting from the areola corresponding part H and going toward the center C of the back On -25%, more preferably from 8% to 23% of the plane, the first junction exists. When the position of the first joining portion is at least 0% of the position from the areola corresponding portion to the center C of the back, it is advantageous that excessive tension is not applied to the areola corresponding portion. On the other hand, when the position of the joining portion is less than 25% of the position from the areola corresponding portion to the center C of the back, the force to pull the breasts toward the body can be easily exerted, which is advantageous.

As for the second joining portion, with respect to the above-mentioned plane S, 50% to 100%, preferably 50% to 85%, and 50% to 100%, preferably 50% to 85%, of the line segment I on the line segment I, starting from the areola corresponding portion H toward the back center C, More preferably, the second joining portion exists on the plane at a position of 55% to 80%. When the position of the second joining portion is more than 50% of the position from the areola corresponding portion to the center of the back, it is easy to apply tension to the areola corresponding portion, which is advantageous. On the other hand, when the position of the joining portion is less than 100% of the position from the areola corresponding portion to the center of the back, the force to pull the breasts toward the body is easily exerted, which is advantageous.

Regarding the joint portion between the flap portion 109 and the bra main body, the joint portion exists in 0% of the line segment I on the plane S defined above, starting from the areola corresponding portion H and going toward the center C of the back. It is only necessary to be on the plane at the positions of ˜25% and 50% to 100%, and the joining portion may also exist in a place other than the above-mentioned plane. However, from the viewpoint of obtaining a better damping effect of the flap portion 109, it is more preferable that, with respect to the above-mentioned plane S, on the above-mentioned line segment I, start from the corresponding part of the areola and go toward the center C of the back. For example, there is no joining portion on the plane at the positions of more than 25% and less than 50%, or 25% to 55%, or 28% to 60%.

The boundary between the cup portion 102 and the wing portion 103 is usually on the plane S at a position of 25% to 35% from the position of the corresponding part of the areola to the center C of the back on the line segment I. Therefore, when the joining portion exists on the above-mentioned plane at the position of 0% to 25% and the position of 50% to 100%, the flap portion 109 can be positioned on each of the cup portion 102 and the wing portion 103, The location where the shock absorption is desired engages the bra body and is thus advantageous.

The joining portion between the flap portion 109 and the bra main body can be formed in a line shape (typically a belt shape having a predetermined width), a dot shape, or the like. For example, it is possible to form joining portions linearly extending substantially in the vertical direction on the left and right cup portions 102 and the left and right wing portions 103 . In a preferred embodiment, the flap portion 109 engages with the bra body at two regions, a partial region of the cup portion 102 and a partial region of the wing portion 103, and the flap portion 109 has a region that does not engage with the bra body . In a preferred embodiment, the flap portion 109 is superimposed on the area formed by connecting the area 107a which is a part of the cup portion 102 and the area 107b which is a part of the wing portion 103 of the bra main body. The armpit reinforcement including the region 107 a and the region 107 b can be formed using the flap portion 109 . That is, the underarm reinforcement part is composed of a joined fabric including a bra body part and flap parts 109 .

In a preferred embodiment, the flap portion 109 is joined to the bra main body in a region including both ends of the flap portion on the cup portion 102 side and the wing portion 103 side.

In a preferred embodiment, the flap portion 109 engages the bra body with a space therebetween. In this embodiment, it is sufficient that the flap portion 109 covers at least a region including a part of the cup portion 102 and at least a part of the wing portion 103 of the bra main body. Furthermore, the flap portion 109 may be connected to the bra main body in an area including at least a part of the peripheral edge of the flap portion 109 (for example, both the end on the cup portion 102 side and the end on the wing portion 103 side). The flap portion 109 may be joined to the bra main body only by the portion of the flap portion 109 other than the peripheral edge. The flap portion 109 engages the bra body in such a way that there is a space between it and the bra body. Here, the space refers to the area sandwiched by the joint part, or surrounded by the joint part, and the flap part 109 is not joined to the bra main body. In order to form the above-mentioned space, it is preferable that the joining portion is formed in a shape such as two or more points or two or more lines. For example, taking two or more points as an example refers to a combination of one or more points located in the area of the cup portion 102 and one or more points located in the wing portion 103 . In addition, for example, taking two or more lines as an example means a combination of the cup part side joint part 107aS and the wing part side joint part 107bS shown in FIG. 2 . For example, in the case of forming a junction of two dots, the meaning of space refers to the area where the two points are connected in the flap part 109 and the area where the two points are connected in the bra main body. the area between. In addition, in this space, the flap part 109 and the bra main body may be in an unjoined state, or the flap part 109 and the bra main body may be in contact with each other. According to the above-mentioned structure, when the bra is worn, tension can be generated between the joining parts by utilizing the difference in tensile stress between the fabric of the flap part 109 and the fabric of the bra main body, and thus a vibration damping effect can be exhibited.

Referring to FIG. 2 , in a specific embodiment, the flap portion 109 is at least at both ends of the end positioned at the cup portion 102 side and the end positioned at the wing portion 103 side, that is, includes an end positioned at the cup portion 102 side and an end positioned at the wing portion 103 side. The region between the ends engages with the bra body, and the flap portion 109 has a region that does not engage with the bra body. In a preferred embodiment, as shown in FIG. 2 , the bra main body and flaps 109 are joined only at cup side joints 107aS and wing side joints 107bS, and the flaps 109 are joined at other places except for these two places. Areas that do not join the body of the bra. The presence of the flap portion 109 enables the force of the flap portion 109 to be pulled from the end portion on the cup side toward the wing side to act when the bra is worn, whereby a vibration damping effect can be exhibited.

In terms of the ratio of the area of the flap portion 109 that is not joined to the bra main body to the area of the flap portion 109 that receives tension when the bra is worn, from the viewpoint of obtaining a good vibration damping effect, this The proportion is preferably 30% or more, more preferably 60% or more, and even more preferably 80% or more. From the viewpoint of firmly joining the flap portion 109 and the bra main body, the above-mentioned ratio is preferably 99.5% or less, and more preferably 99.5% or less. 99% or less, more preferably 98% or less. In addition, with regard to the area of the above-mentioned region that is subjected to tension when wearing the bra, the intersection line that is perpendicular to the line segment I and passes through the surface of the joint portion and the surface of the flap portion 109 is the closest intersection line from the front center. The area of the flap fabric that exists in the region sandwiched by the intersection line closest to the back center C.

Referring to Figure 3, draw a straight line L1 tangent to the bottom of the bra, and assume a line segment L2 in such a way that the distance from the straight line L1 to the following boundary point Pa is the shortest. The boundary point Pa is the upper edge of the cup and the cup The boundary point between the axillary margins. Among the intersections between the plane passing through the line segment L2 and perpendicular to the line segment L2 and the fabric surface (the outer surface when viewed from the wearer's point of view) of the bra main body, the intersection line with the largest length in the area 107a is selected, and the intersection line is selected. The intersection point of the line and the armpit edge of the cup is M1, the intersection point of the intersection line and the edge of the armpit reinforcing part end side of the cup side joint portion 107aS is M2, and the points on the intersection line between M1 and M2 The line segment between is set as a line segment La. The point of intersection of this line of intersection and the edge of the wing side joint portion 107bS on the side of the armpit reinforcement portion end is defined as M3. A line segment between M1 and M3 on this intersection line is defined as a line segment Lb.

The length of the wing 103 means: from point M1 to the center of the back of the wing 103 (in the case of a hook at the end of the wing 103, the boundary with the hook, if there is no hook , refers to the shortest length of the cloth until the center of the back when the bra is worn, such as point Pc) in FIG. 4 .

The length of the wing portion 103 is moderate when it is 5 cm to 15 cm.

The length m1 of the flap part 109 means the shortest length of the cloth which connects the point M2 and the point M3 of the joint part with the bra main body part on the flap part 109 . And let the total length of the line segment La and the line segment Lb on a bra main body part be length m2 between the joint parts on a bra main body part. Typically, bras are worn in a stretched state. Preferably, the lateral elongation E1 of the flap portion 109 when worn satisfies the following two conditions:

E1＝{(1+E2/100)×(m2/m1)－1}×100 (1)

100/YR1≤E1≤1000/YR1 (2).

Here, the lateral direction of the flap portion 109 refers to the extending direction of the line segment formed when the length of the cloth connecting the point M2 and the point M3 is the shortest. Here, the length m1 of the flap portion 109 and the length m2 between the joints on the bra main body are values determined by the design and appearance of the bra. Bust)/(perimeter of the lowermost part of the bra)×100}-100(%), and the elongation E2 is a numerical value determined by the size.

Using these numerical values, the lateral elongation E1 of the flap portion 109 when the bra is worn is calculated according to the formula (1). If the elongation E1 satisfies the formula (2), the vibration damping property can be fully exhibited, and the uncomfortable feeling when wearing or operating can be suppressed, so it is preferable. In the formula (2), YR1 is the transverse Young's modulus of the flap portion 109 described later. When the elongation E1 calculated according to the formula (1) does not satisfy the formula (2), YR1 is changed by changing the material of the flap portion 109 so as to satisfy the formula (2). Or, it is also preferable to change in the following manner: by changing the design, appearance shape, size, by changing any one of the length m1, the length m2, the elongation E2 or their combination, the elongation E1 is satisfied (2 )Mode.

Preferably, the lateral stress σ1 generated in the flap portion 109 satisfies

100cN/inch≤σ1≤1000cN/inch (3).

If σ1 is more than 100cN/inch, the vibration damping performance can be fully realized. If σ1 is less than 1000cN/inch, the wearing pressure, especially the wearing pressure on the shoulders and the lower parts of the breasts will not be too high, and the feeling of restraint and sticking can be suppressed. Sensual. Preferably 200cN/inch≤σ1≤800cN/inch, particularly preferably 300cN/inch≤σ1≤600cN/inch. σ1 corresponding to E1 can be determined from the separately measured stress-strain relationship of the material used for the flap portion 109 .

Moreover, preferably, the ratio of the transverse Young's modulus YR1 of the flap part 109 to the transverse Young's modulus YR2 of the wing part 103 satisfies:

0.7≤YR1/YR2≤3 (4).

Here, the lateral direction of the wing portion 103 refers to the direction along the line segment Lb. If 0.7≤YR1/YR2, then compared with the length of the wing 103, the length of the aileron 109 will not appear extremely short, so that sufficient vibration damping can be obtained under the premise of making the appearance beautiful, if YR1/ YR2≦3, compared with the length of the wings, the length of the ailerons 109 will not be extremely stretched, so that the stress that reflects the vibration damping can be obtained, and the feeling of being clamped at the lower part of the breast can be suppressed. It is preferably 1≦YR1/YR2≦2.5, particularly preferably 1.1≦YR1/YR2≦2. YR1 and YR2 are values calculated from the partial slope of 0% to 10% of the strain of the stress-strain relationship obtained by a conventional method based on the strip method in the JIS L1096.8.12.1A method.

The method of determining the shape and physical properties of the flap portion 109 is as follows. Determine the length m1, length m2, and elongation E2 according to the design, appearance, and size of the bra, and calculate the lateral elongation E1 of the flap portion 109 according to the formula (1). Using the transverse Young's modulus YR1 of the flap portion 109, it was confirmed from the formula (2) whether or not the above-mentioned elongation E1 was in an appropriate range. At this time, it was also checked whether or not the ratio of the transverse Young's modulus of the flap portion 109 and the wing portion 103 satisfies the expression (4). When the elongation E1 is not within the appropriate range, the fabric used for the ailerons can be changed by changing the Young's modulus YR1, the design and appearance of the bra can be changed by changing the length m1 and m2, and the bra can be changed by changing the elongation E2. Change the size of the bra to make the elongation E1 in an appropriate range. Next, according to the stress-strain relationship of the fabric of the flap portion 109, the stress σ1 corresponding to the elongation E1 is obtained, and it is confirmed whether the stress σ1 satisfies the formula (3), so as to determine the shape and physical properties of the flap portion 109 .

When the stress σ1 of the flap portion 109 does not satisfy the formula (3), that is, when the σ1 is less than 100cN/inch, the following countermeasures can be taken: On the premise of satisfying the formulas (2) and (4) , Use a cloth with a larger Young's modulus YR1 to make the flap portion 109, and change the length m1 of the flap portion 109 to a shorter design, thereby increasing the lateral elongation E1 when wearing the bra. Conversely, when σ1 is greater than 1000cN/inch, the following countermeasures can be taken: on the premise of satisfying the formulas (2) and (4), use a fabric with a smaller Young's modulus YR1 to make the aileron part 109, and change the length m1 of the flap part 109 to a longer design, thereby reducing the lateral elongation E1 when wearing the bra.

The height of the flap portion 109 is represented by the length of a line segment (not shown) perpendicular to the straight line L1 on the flap portion, and the larger the height value, the better the vibration damping effect. Thus, it is preferable that the cup part 102 side joint extends over the entire range between the upper and lower ends of the cup, and it is preferred that the wing part 103 side joint extends over the entire range between the upper and lower ends of the wing. Furthermore, it is preferable that the height of the flap portion 109 other than the joining portion is equal to or greater than the height of the bra main body.

The flap portion 109 greatly contributes to improving the vibration damping performance against the vibration of the breast in the X direction, the Y direction, and the Z direction, especially the vibration in the X direction and the Z direction. That is, the flap portion 109 can improve the closeness between the cup and the breast, has an excellent effect of integrating the cup and the breast, and has the effect of preventing the breast from overflowing the bra during the action. In particular, utilizing the vibration damping property in the Z direction, the effect of improving the closeness between the cup and the breast and integrating the cup and the breast can be more effectively exerted. More effectively play the effect of preventing breast overflow bra.

The flap portion 109 is not particularly limited as long as it is a fabric that satisfies the above-mentioned requirements, but examples include the following fabrics: cotton woven fabric, polyester woven/knitted fabric, and woven fabric made of polyamide material. Knitted fabrics containing spandex yarn fibers such as knitted fabrics, knitted gray fabrics with elastic mesh, and bidirectional knitted gray fabrics. Friction between the front side of the bra body fabric and the back side of the flap fabric may affect the vibration damping effect. Therefore, regarding this frictional force, for example, the frictional force between the front side of the bra main body fabric and the back side of the flap fabric is evaluated using KES-SE friction test equipment manufactured by Kato-Tech Co., Ltd. or equivalent equipment. In this case, the frictional force is preferably 0.10 to 0.20, more preferably 0.12 to 0.18. If the friction force is 0.10 or more, the effect of pressing the flap fabric against the bra main body fabric can be easily exhibited well, and if the friction force is 0.20 or less, excessive friction will not be caused. From this point of view, it is easy to exert the effect of pressing the flap fabric. The effect on the main fabric of the bra. The aforementioned frictional force can be adjusted by changing the combination of the fabric of the bra main body and the fabric of the flap portion 109 .

The flap portion 109 can be joined to the bra body by sewing, welding or other methods. For example, when the joining portion of the flap portion 109 to the bra main body is at both ends of the flap portion, the end on the cup portion 102 side and the end on the wing portion side, the flap can be formed by the following method: part 109, that is, the fabric for the bra main body and the fabric for the wing part 109 are stacked together, and at both ends of the end on the cup part 102 side and the end on the side of the wing part, they are sewn, welded or Other methods hold the above fabrics together. When the cup portion 102 has two or more layers, it may be joined to one of the layers, or may be joined to all the layers. When the tensile stress of the surface fabric of the cup main body is small, the fabric will stretch if it is only joined to the surface fabric, and the effect of pulling the cup is not obvious. Joining to avoid stretching of the greige only on the surface.

By pulling the cup obliquely rearward (corresponding to the combined direction of the X direction and the Z direction), the flap portion can draw the breast toward the trunk side, thereby improving the closeness between the cup and the breast. However, at the same time, there is a tendency to draw the breasts further to the side than a bra without flaps. Therefore, at the same time, for the connecting portion, the pulling force generated by the aileron pulls the connecting portion in the left-right direction, thereby extending the connecting portion. Therefore, compared with a bra without flaps, it is easy to generate a gap between the cup and the breast near the connecting portion (the center of the breast). At this time, as far as the bra with the flap part is concerned, by giving the connecting part a predetermined stress, the connecting part can be used as a fixed point, and the pulling force that pulls the breasts to the trunk can be generated again, and the connecting part can be prevented from leaving the skin, so that it can be suppressed. Subtle shaking during movement.

According to another embodiment, by arranging the high stress portion 104 on the upper edge of the cup, the vibration damping effect can be realized. The upper edge high stress portion is configured to extend along the upper edge of the cup. In addition, it is sufficient that the upper edge high-stress portion constitutes at least a part of the substantially peripheral portion of the cup portion.

For the cup part, preferably, the ratio S2/S1 of the stretching stress S2 of the upper edge high stress part to the stretching stress S1 of the cup central part is 2/1 to 400/1. In the present invention, the central part of the cup means a region having a single tensile stress including the top (that is, the position corresponding to the areola of the wearer) of the cup. In the present invention, the tensile stress refers to the following value: the stress (N/2.5cm width, N/2.5cm width, Hereinafter, it is simply referred to as N) and the stress (N) at 10% stretching in the lateral direction, and their average value is calculated as the tensile stress (hereinafter, also referred to as the vertical and horizontal average tensile stress, or simply the tensile stress).

When the cup portion has two or more layers (for example, two layers of a polyurethane pad and a fabric), the tensile stress is measured in a state where the two or more layers are stacked.

If the ratio S2/S1 is equal to or greater than 2/1, the effect of suppressing the swaying of the breast in the high-stress portion becomes significant. On the other hand, if the said ratio S2/S1 is 400/1 or less, the stretching stress of this high stress part will not become too high, and it can avoid becoming a bra which is stiff and hard to fit. The above ratio S2/S1 is preferably 3/1 to 100/1, more preferably 5/1 to 80/1, particularly preferably 10/1 to 60/1.

The upper edge high stress portion greatly contributes to improving the vibration damping performance against the vibration of the breast in the X direction, the Y direction, and the Z direction, especially the vibration in the X direction and the Y direction. When walking, running, etc., the human body moves up and down, and the breasts accommodated in the cup move up and down with a slight delay relative to the movement of the human body. By providing the upper edge high stress portion, upward swaying of the breast in this case can be effectively suppressed. Moreover, in addition to the up and down motion of the human body when walking, running, etc., there is also a left and right motion that rotates the body. Moreover, when the upper edge high stress portion is provided in such a manner as to extend along the upper edge of the cup, usually the upper edge high stress portion can be installed in a slightly inclined manner relative to the horizontal direction. Thereby, it is possible to suppress the inward swaying of the breast due to the left and right movement of the human body, that is, the swaying of the breast in the X direction can be suppressed.

Preferably, the upper edge high stress portion is continuously arranged on the upper portion of the cup portion with a width of 0.5 cm to 5.0 cm. More preferably, the above-mentioned width is 1.0 cm to 4.0 cm. Also, the aforementioned width can be arbitrarily designed. For example, the upper edge high stress portion can be designed so that the width of the upper edge high stress portion is narrower on the front center side of the wearer's body in the cup portion, and wider on the armpit side of the cup portion.

Furthermore, according to another embodiment, by arranging the high-stress portion 105 at the lower edge of the cup, a vibration damping effect can be exhibited. The lower edge high stress portion is arranged to extend along the lower edge of the cup. In addition, it is sufficient that the lower edge high-stress portion constitutes at least a part of the substantially peripheral portion of the cup portion.

For the cup part, preferably, the ratio S3/S1 of the stretching stress S3 of the lower edge high stress part to the stretching stress S1 of the cup central part is 2/1 to 400/1. As long as S3/S1 is 2/1 or more, the effect of suppressing the swaying of the breast in the high-stress portion is more obvious. On the other hand, if the said ratio S3/S1 is 400/1 or less, the stretch stress of this high stress part will not become too high, and it can avoid becoming a bra which is stiff and hard to fit. The above ratio S3/S1 is preferably 3/1 to 100/1, more preferably 5/1 to 80/1, particularly preferably 10/1 to 60/1.

The lower edge high stress portion greatly contributes to improving the vibration damping performance against the vibration of the breast in the X direction, the Y direction, and the Z direction, especially the vibration in the Y direction. When walking, running, etc., the human body moves up and down, and the breasts accommodated in the cup move up and down with a slight delay relative to the movement of the human body. By providing the lower edge high-stress portion, in this case, shaking of the breasts such as downward slapping can be effectively suppressed.

Preferably, the lower edge high stress portion is continuously arranged at the lower portion of the cup portion with a width of 0.5 cm to 4.0 cm. More preferably, the above-mentioned width is 1.0 cm to 3.0 cm. Also, the aforementioned width can be arbitrarily designed. For example, the width can be designed such that the width is narrower on the front center side of the wearer's body in the cup portion and wider on the armpit side of the cup portion.

When the upper edge high stress portion and the lower edge high stress portion are provided at the same time, preferably, the ratio of the sum of the areas of the upper edge high stress portion and the lower edge high stress portion to the entire area of the cup portion is 10% to 50%. %, particularly preferably 20% to 40%. When the above-mentioned ratio is 10% or more, the reinforcing effect is more obvious, and even if the cup is large, a good effect of suppressing the shaking of the breast can be obtained. On the other hand, when the said ratio is 50 % or less, the uncomfortable feeling at the time of wearing can be avoided favorably. The area ratio of the upper edge high stress portion and the lower edge high stress portion is not particularly limited. The aforementioned ratio can be calculated by, for example, stacking thin paper on the surface of a cup and obtaining the mass of the portion of the paper corresponding to the area of each portion of the cup.

The tensile stress S2 of the upper edge high stress portion and the tensile stress S3 of the lower edge high stress portion are both preferably 20N to 500N, more preferably 50N to 400N, and even more preferably 100N to 350N. When the above-mentioned elongation stress is 20N or more, the reinforcing effect is more obvious, and when the above-mentioned elongation stress is 500N or less, discomfort during wearing can be well avoided. The ratio of the tensile stress of the upper edge high stress portion to the lower edge high stress portion is not particularly limited. Furthermore, the tensile stress at the center of the cup is preferably 0.5N to 50N, more preferably 1N to 20N, still more preferably 1.5N to 15N, particularly preferably 2N to 10N. When the above-mentioned tensile stress is 0.5N or more, it is less likely to cause cracks during wearing or washing, and when the above-mentioned tensile stress is 50N or less, discomfort during wearing can be well avoided.

In the case where the upper edge high stress portion and/or the lower edge high stress portion are formed in the cup portion, it is also possible to place a knit structure at a predetermined position of the cup, use a yarn, or change the denier to increase the stretch stress. Furthermore, it is possible to use a method of arranging a reinforcing cloth to be an upper edge high stress portion or a lower edge high stress portion by sewing or bonding on the inner side of the bra (that is, the side close to the wearer's skin surface). Alternatively, in the case of using polyurethane pads in cups, it is also possible to use a method such as: when molding the polyurethane pad, etc., sandwiching a woven fabric or the like to be a high-stress portion, thereby improving Pad local stiffness.

In a specific embodiment, the average cross-sectional area of the shoulder strap portion serving as the vibration damping portion is 20 mm ² to 120 mm ² . In this case, good vibration damping properties can be achieved. It is more preferable that the average cross-sectional area is 25 mm ² to 100 mm ² . The cross-sectional area means the width (mm) of the shoulder strap x the thickness (mm) of the shoulder strap. As for the average cross-sectional area, measure the cross-sectional area of both ends of the shoulder girdle, and measure the cross-sectional area of each portion obtained by dividing the portion between the two ends into 10 equal parts, and calculate the measured cross-sectional area The numerical average value of is taken as the average cross-sectional area. Specifically, the average cross-sectional area can be calculated as follows.

With reference to Fig. 1 and Fig. 4, the average cross-sectional area of the shoulder girdle is the arithmetic mean of the following cross-sectional area: the width W1 * thickness ( not shown), the cross-sectional area calculated by the width W2 of the end (that is, the root) of the shoulder portion on the wing side (that is, the rear side) x the thickness (not shown), and the shoulder The part of the belt portion between the end on the cup side and the end on the wing side is divided into 10 equal parts along the length direction of the shoulder girdle, and the sections obtained after equal division (i.e., nine sections) are passed through each section The cross-sectional area calculated by the width×thickness (not shown) (for example, width W3×thickness in FIG. 1 ). In addition, the width W1 refers to the shortest distance from the connection point P1 near the armpit between the shoulder strap and the cup to the center of the shoulder strap near the chest, and the width W2 refers to the distance between the shoulder strap and the wing. The shortest distance from the connection point P2 on the armpit to the center of the backrest side of the shoulder belt. Also, if there is an adjuster that can adjust the length of the shoulder strap, measure and calculate after adjusting the length of the shoulder strap to the maximum using the adjuster.

The weight of the breasts is exerted on the shoulder girdle to a greater extent and this force can become very high especially if the wearer has a large cup size. Therefore, in the case of a sports bra or a bra with a large cup size, it is necessary to design the width of the shoulder girdle to be enlarged. However, when the width of the shoulder girdle is wide, it loses sexiness and is poor in aesthetics. Even if the width of the shoulder girdle is narrow, by increasing the cross-sectional area of the shoulder girdle, vibration can be absorbed and the cup portion can be stably supported. When the average cross-sectional area of the shoulder girdle is less than 20 mm ² , the effect of absorbing vibration tends to be insignificant. If the average cross-sectional area of the shoulder girdle is larger than 120 mm ² , vibrations can be absorbed, but if the width is increased, the aesthetics will be damaged, and if the thickness is increased, there will be roughness, stiffness, and other tactile sensations. Trends affecting outerwear. However, in the case of reinforcing other parts of the bra as described above, as long as the average cross-sectional area of the shoulder girdle is about 80% or more of 20 mm ² , excellent vibration damping properties of the bra can be ensured. For example, when one or more of the upper edge high stress portion, the lower edge high stress portion, and the flap portion are provided, the average cross-sectional area of the shoulder strap portion can be 16 mm ² or more and 120 mm ² or less.

Preferably, the back connection center of the shoulder girdle is located at a distance of 25% to 60% of the length of the wing from the center of the back of the wing toward the cup side, more preferably 25% to 60% of the length of the wing. 30% to 50% of the position. When the distance between the back side connection center of the shoulder strap part and the back center of the wing part is 25% or more of the length of the wing part, there is an advantage of excellent shock absorption, and the distance between the back side connection center of the shoulder strap part and the wing part When the distance between the center of the back is 60% or less of the length of the wings, there is an advantage that the shoulder straps are not easy to slip off. In addition, the length of a wing part can be prescribed|regulated as mentioned above. And, with regard to the dorsal connection center of the shoulder strap portion, draw a vertical line from the midpoint of the line segment representing the width W2 in FIG. 4 toward the line segment representing the length of the wing portion. means the intersection of the perpendicular with the line segment representing the length of the wing.

The elongation (capacity) of the shoulder girdle is measured and calculated by elongation of the shoulder girdle when a weight of 0.5 N/ ^mm2 is applied in the length direction of the shoulder girdle. The ratio is preferably 30% to 80%, more preferably 40% to 70%. The elongation can be measured based on the strip method tensile test in the JIS L1096.8.12.1A method. The entire shoulder girdle is held and divided, and the load used for the measurement is obtained by multiplying the average cross-sectional area by 0.5N. load. As long as the capacity of the shoulder girdle is 30% or more, vibrations can be absorbed well without being too stiff. As long as the capacity of the shoulder girdle is 80% or less, vibrations can be well absorbed without excessive stretching.

Preferably, the shoulder girdle 110 locally has a low-stress portion whose tensile stress is smaller than that of other parts of the shoulder girdle. By providing such a low-stress portion as described above, concentration of wearing pressure can be prevented, and comfort can be improved. It is desirable, for example, referring to FIG. 1 , to have a low stress portion in the region including the shoulder portion 110 a that has a lower tensile stress than the rest of the shoulder girdle portion.

The shoulder girdle greatly contributes to improving the vibration damping performance against the vibration of the breast in the X direction, the Y direction, and the Z direction, especially the vibration in the Y direction. When walking, running, etc., the human body moves up and down, and the breasts accommodated in the cups move up and down with a slight delay, but the cups are hung from above by using the shoulder straps with a cross-sectional area greater than a certain value. Can suppress the up and down movement of the breast. Moreover, by installing the shoulder straps near the armpits instead of near the center, it can be very helpful to improve the vibration of the breasts in the X direction, Y direction, and Z direction, especially in the X direction. vibration damping properties. By attaching the shoulder straps close to the armpits, the force that pulls the cups upward can be exerted, so it is possible to effectively suppress breast shaking caused by the rotation of the human body when walking, running, etc. . In terms of the mounting position of the shoulder straps, it is preferable that the front of the shoulder straps be mounted within 3 cm of the underarm end of the cup along the approximate X direction, and the rear of the shoulder straps be mounted at a distance from the back of the cup. The midpoint between the side center and the center of the underarm (that is, the middle between the center of the front and the center of the back) is within 5cm of the side of the armpit. Furthermore, since the shoulder straps pull the front cups toward the back of the body, the shoulder straps also contribute to improved vibration damping in the Z direction.

As mentioned above, with regard to the bra of the present invention, what is used in the cup connecting portion is a member with predetermined physical properties, and the vibration damping portion is a flap portion, a cup upper edge high stress portion, a cup lower edge high stress portion, and a In the case of one or a combination of two or more of the shoulder parts with a specific average cross-sectional area, especially, in the case of having an aileron portion, especially, when the aileron portion has specific physical properties and the wing portion and the aileron When the airfoil has a specific ratio of physical properties, an exceptionally excellent vibration damping effect can be exhibited. In particular, the vibration damping properties can be further improved by combining the vibration damping effects in the X direction, the Y direction, or the Z direction, respectively. For example, combining two or more of the connecting portion, the flap portion, the high-stress portion at the upper edge of the cup, the high-stress portion at the lower edge of the cup, and the shoulder girdle can reduce and disperse the tension in the X, Y, and Z directions. Shaking, this practice is very preferred. Moreover, in the case where the damping portion is a combination of two or more of the flap portion, the high-stress portion at the upper edge of the cup, the high-stress portion at the lower edge of the cup, and the shoulder portion with a specific average cross-sectional area, it is also possible to make each part The lower limit of the preferred range of the characteristic values (in particular, the tensile stress ratio of the above-mentioned high stress portion and the average cross-sectional area of the shoulder girdle portion) is reduced by about 20%. For example, when the average cross-sectional area of the shoulder girdle is 20 mm ² to 120 mm ² , good vibration damping properties can be obtained. When the area is 16 mm ² to 120 mm ² , good vibration damping properties can be obtained.

Each member may be formed by independent fabrics, or may be formed by a continuous monolithic fabric, and in the case of a monolithic fabric, the boundaries between the members are defined according to the shape. In the case of the latter, especially, regarding the outer edge of the cup, if the edge of the raised shape of the cup is more obvious, the outer edge of the cup is drawn at the position of the edge of the raised shape. If the edge of the raised shape is not obvious, draw the outer edge of the cup part at a position that can be regarded as an imagined edge based on the raised shape.

It is also possible that the damping portion is configured as a reinforcing portion made of a fabric independent of the bra main body fabric, for example, as described above, the flap portion is attached to the gray fabric constituting the bra main body by joining (in the present invention, Also known as the main gray cloth.). Compared with the case where the reinforcing part is provided in the main body fabric by means of switching ability (that is, the tensile stress can be strong or weak), the method of providing the reinforcement part as described above has the advantage of improving the vibration damping performance.

The main body fabric may be formed by mutually independent fabrics, or may be formed by continuous monolithic fabrics, and in the case of monolithic fabrics, the boundaries between members are divided according to shapes. In the case of the latter, especially, regarding the outer edge of the cup, if the edge of the raised shape of the cup is more obvious, the outer edge of the cup is drawn at the position of the edge of the raised shape. If the edge of the raised shape is not obvious, draw the outer edge of the cup part at a position that can be regarded as an imagined edge based on the raised shape.

Referring to FIG. 5 , in a specific embodiment, when the bra is configured so that the distance between the end point Q1 and the end point Q2 on the front center side of the shoulder girdle portion near the cup portion is the largest, the front portion of the shoulder girdle portion near the cup portion The terminal points Q1 and Q2 on the center side are connected with the front central lower terminal point Q3 of the connecting portion to form a triangle T, and the ratio of the area of the part 111 not covered by the fabric of the bra to the area of the triangle T is preferably more than 60%, more preferably Preferably it is 70% or more, More preferably, it is 80% or more, Most preferably, it is 100%. This triangle forms the so-called cleavage section. When the above ratio is 60% or more, it is possible to prevent cleavage from being blocked, and to achieve good aesthetics. For example, the bra of the present invention can have a specific vibration value as will be described later, which is realized by having a specific damping portion. The bra of the present invention is advantageous in that it is excellent in vibration damping properties even in the state where the ratio is 60% or more, that is, the so-called cleavage is exposed.

With reference to Fig. 6, in terms of the length of the vertical direction of the connecting portion, when the bra is arranged so that the distance between the end points of the shoulder straps near the front center of the cup is the largest, the bottom point of the cup is placed. The midpoint K of the line segment connecting B1 and point B2 and the midpoint R of the line segment connecting the end point Q1 and end point Q2 on the front center side of the shoulder girdle portion near the cup portion are the line segment L3, on the line segment L3 The ratio L4/L3 of the length of the line segment L4 corresponding to the position of the connecting portion to the length of the line segment L3 is preferably 0.10 to 0.50, more preferably 0.15 to 0.45. In addition, the line segment L4 corresponding to the connection portion on the line segment L3 refers to a set of intersection points of the perpendicular drawn from the connection portion to the line segment L3 and the line segment L3. By making the above-mentioned ratio 0.10 or more, it is possible to ensure a sufficient installation area of the connecting part, so that the cup and the breast can be closely adhered to at the center of the cup. Since the joint becomes a fixed point, the breast can be firmly fixed in the area from the front of the cup to the side of the cup, and fine vibrations can be suppressed. And by making the above-mentioned ratio 0.50 or less, the area of the connecting portion can be prevented from being too large, a sufficiently large exposed area of the breast can be maintained, and it has high aesthetics. At the same time, the connecting portion can be prevented from being too rigid, so the Wearing comfort.

The bra of the present invention exhibits good shock absorbing properties by having the specific shock absorbing portion. Therefore, shaking of the breast can be suppressed, and the wearing pressure of each part can be kept below 50hPa. Therefore, the maximum wearing pressure of the present invention can be kept below 50hPa, and discomfort and restraint during wearing can be avoided. Generally speaking, in order to suppress the shaking of the breasts, strong restraints are often carried out, especially bras with very high pressure on the shoulders are very common. However, when the wearing pressure of each part of the bra is greater than 50 hPa, there is generally a tendency to make people feel uncomfortable. In the present invention, the movement of the breast in the X direction, Y direction, and Z direction is suppressed and dispersed, so that concentration of wearing pressure can also be prevented. In particular, the above-mentioned reinforcement treatment for the shoulder straps is excellent in the effect of distributing the wearing pressure. The maximum wearing pressure is more preferably 45 hPa or less, still more preferably 40 hPa or less. On the other hand, from the viewpoint of suppressing shifting of the bra during wearing and suppressing breast shaking, for example, the maximum wearing pressure can be preferably 10 hPa or more, more preferably 13 hPa or more, and even more preferably 15 hPa or more.

The raw materials of each component of the bra of the present invention (that is, the components that respectively constitute the bra main body and the reinforcing part) are not particularly limited, and it is recommended to use synthetic fibers such as polyester fiber and polyamide fiber, rayon, cupro ammonia fiber, acetic acid fiber, etc. Cellulose fibers such as fiber, and natural fibers such as cotton and hemp. The structure of the fabric constituting each member is also not particularly limited, and knitted fabrics, woven fabrics, nonwoven fabrics, and the like can be used. Furthermore, crimped fibers may also be used. In the present invention, it is effective to arrange fabrics having moderate stretch properties for each member. For each member, it is recommended to use stretchable knitted gray fabric obtained by cross-knitting polyurethane elastic fibers. Moreover, the gray cloth of the cups and wings can use double needle bed circular knitting (Japanese: ダブル丸) gray cloth, tricot warp knitting (Japanese: トリコット) gray cloth, Raschel warp knitting (Japanese: ラッセル) gray cloth, etc., it is recommended to use warp-plain weave (Japanese: トリコットハーフ) gray cloth. The knitting gauge of the knitting machine used is preferably 20GG to 40GG. In addition, it is recommended to use woven fabrics or warp-knitted fabrics with inserted warp yarns for high-stress parts. Materials such as lace with a little stretch are also excellent in design, so lace and other materials are highly recommended.

Each member can consist of monofilaments or multifilaments. Matting agents such as titanium dioxide, stabilizers such as phosphoric acid, ultraviolet absorbers such as hydroxybenzophenone derivatives, crystal nucleating agents such as talc, slippery agents such as fumed silica (AEROSIL), etc. may be contained in the multifilament.

Furthermore, it is desirable to give sweat-absorbing processing to the fabric used for each member.

When using polyurethane pads for cups, it is recommended to use polyurethane pads with a thickness of 2 mm to 15 mm, but it is also preferable to use three-dimensional knitted fabrics for cups because it can improve air permeability.

The fabric used for the reinforcing part is not particularly limited, and can be composed of the following fabrics: cotton woven fabric, polyester woven/knitted fabric, polyamide woven/knitted fabric, or elastic mesh knitted fabric, bidirectional weave Fabrics containing polyurethane elastic fibers, such as knitted gray fabrics.

The bra of the present invention is extremely excellent in vibration damping properties. In order to objectively evaluate the degree of breast shaking, the following method can be used. Let five subjects with a height of 160cm±8cm and a value of (upper bust-lower bust) of 17.5cm or more wear bras, and let the subjects walk on a treadmill at a speed of 5.5km/h and at a pace of 1 minute. At a pace of 150 steps, trot with one foot off the ground when landing. In this case, reflective balls with a diameter of 2.0 cm were attached to the clavicle and areola in advance, and two high-speed cameras were used to photograph the reflective balls for 20 seconds. As an index of breast shaking when trotting so that the shaking of the clavicle is about 13 cm, the three directions of the horizontal (X direction), vertical (Y direction) and cup depth direction (Z direction) are calculated within 20 seconds. The (shake of the areola) - (shake of the clavicle) (cm) of (the average value of the maximum value) - (the average value of the minimum value) (cm). Here, the X direction refers to the lateral direction of the bra, and the Y direction and the Z direction are respectively perpendicular to the X direction. Take the maximum of the values in the three directions as the breast shaking value (cm) when wearing, and divide this value by the value (cm) of (upper bust - lower bust) to obtain the shaking value. When the wobble value is less than 0.4, the wobble of the breast is small, which is favorable. The sloshing value is preferably 0.3 or less, more preferably 0.2 or less. The smaller the wobble value is, the more preferable it is. However, from the viewpoint of avoiding excessive pressure and easily obtaining a good wearing feeling, the wobble value is preferably 0.03 or more, for example.

In order to objectively evaluate the degree of slight swaying of the breast in the cup according to the present invention, the following method can be used. When evaluating the swaying of the breasts from the appearance as described above, a 3-axis accelerometer (SA12ZSCA: Fuji Ceramics Co., Ltd.) Run on a treadmill with one foot off the ground at a pace of 150 steps per minute at a speed of 5.5 km/h. Measure this situation for 20 seconds, wherein, measure x-direction (transverse) acceleration, y-direction (longitudinal) acceleration, z-direction (cup depth direction) acceleration, and calculate the respective (average values of the maximum values) of the accelerations in the three directions value) - (average of minimum value) (m/s ² ). A lower acceleration means less microscopic wobbling of the breast in the cup, so ideally, the lower the acceleration value, the better. In particular, if the acceleration is 50 m/s ² or less, the fine vibration of the breast in the cup can be suppressed, and the uncomfortable feeling when performing an action in the wearing state can be reduced.
