Description

Underwear and bra

The present invention relates to an undergarment and a bra which suppresses the shaking of the chest when wearing. In more detail, the present invention relates to a method for reducing the feeling of rubbing (rubbing) of breasts caused by shaking during movement and the pain associated with rubbing by using it in conjunction with a bra, thereby having a highly comfortable suppression Underwear with the effect of shaking of the chest during the action and a bra integrated with the underwear.

Bras are one of the main purposes of beautifully shaping the shape of the chest, but restraining the shaking of the chest during exercise is also one of the major effects. However, even when wearing a bra, when walking or running, the chest often shakes a lot. Especially when the size of the chest is large, the shaking becomes very large, which not only brings discomfort and becomes a burden to the wearer, but also causes the chest to sag. The method of wearing a bra with strong pressure is effective as a method of reducing the shaking, but wearing comfort in this method is significantly deteriorated. In addition, during exercise, especially the shaking of the chest becomes larger, so it becomes an obstacle to the wearer's movement, or becomes a burden, which makes the problem more obvious. Therefore, many sports bras have been developed as bras that reduce the shaking of the chest during exercise (Patent Documents 1 and 2). However, in order to suppress sloshing during exercise, sports bras are mostly designed to cover the cleavage part of the chest with a large covering area. Therefore, there is dissatisfaction on the comfort surface due to the high wearing pressure due to the large coverage area when wearing.

Patent Document 3 describes a brassiere including a pair of cup portions, a coupling portion connecting the front center side of the cup portion to each other, a side wing portion, and a shoulder strap connecting the end portions to the pair of cup portions and the side wing portion The cup portion has at least a pad, the pad has a high stress portion, the high stress portion extends along the upper edge of the pad, or the lower edge of the pad, or both, and is a stretch of the high stress portion The ratio S2/S1 of the stress S2 to the tensile stress S1 of the breast peak of the pad is 2/1 to 80/1.

In the technique described in Patent Document 3, the auxiliary side wing portion is arranged on the brassiere body in the area from the cup portion to a part of the side wing portion. By arranging the secondary wing made of grey fabric with different tensile stress from the fabric of the bra body, the difference between the tensile stress of the body fabric and the secondary wing during wear is directed from the junction of the secondary wing of the cup The side wing part acts as a pulling force and can exert anti-vibration effect.

In the above-mentioned brassiere, the effect of the auxiliary flanks, even if the cleavage part of the chest is opened larger, it is possible to suppress the shaking during the movement without impairing the comfort. However, although the subjective evaluation of the vibration resistance and comfort when wearing this bra is improved compared to a normal bra, and the sway value is also reduced, there is a case where a slight discomfort occurs on the comfort surface.

In the technology described in Patent Document 4, a clothing material has been developed which covers the portion from the shoulder to the abdomen and back, and it is worn by reinforcing the front surface around the back and breast wraps with the pressing part The posture of time is set to a good state.

In the technology described in Patent Document 5, by using a tube-shaped fabric with an opening at the upper opening, the lower opening, and the armhole for the bra, the friction between the breast and the bra can be improved Discomfort.

In the above underwear, by wearing on the inner side of the bra, although the discomfort of friction and the like can be reduced to a certain extent, considering the movement relative to the bra and the underwear may move together without sufficient rubbing Inhibitory effect. In addition, it is assumed that this effect cannot obtain a sufficient suppression effect on the shaking of the breast that becomes proportionally larger according to the size of the breast.

[Problems to be solved by the invention]

Therefore, the problem to be solved by the present invention is to provide an undergarment and a bra excellent in vibration resistance of the chest during exercise, that is, excellent in vibration resistance, and to provide a comfort in addition to vibration resistance Underwear and bra. [Technical means to solve the problem]

The inventors found that the measurement of the accelerometer found that even in the bra as shown in Patent Document 3, the breasts were slightly shaken in the three-dimensional direction in the products that restrained the shaking of the entire breast. If observed by self-acceleration, it can be seen that although the product that suppresses the sway of the entire breast can suppress the large sway of the chest, it generates acceleration due to subtle vibrations in all directions, and the chest is always subject to the shock caused by the acceleration. Therefore, as the chest moves slightly in the cup, friction with the cup occurs, and the skin surface of the breast rubs on the surface of the cup. Considering this situation, although it can restrain the shaking during wearing, it becomes the cause of feeling uncomfortable (especially the rubbing sensation of the skin on the chest and the pain caused by rubbing during the action). Therefore, in order to further improve wearing comfort, consideration must be given to improving the rubbing (rubbing) between the cup and the breast surface in the cup to reduce the rubbing feeling and the pain caused by the rubbing.

The present inventors have made intensive studies in order to solve the above-mentioned problems, and as a result of repeated experiments, it has been found that by wearing underwear on the inner side of the bra, the friction between the cup portion of the bra body and the skin can be reduced, and the shaking of the chest can be reduced The present invention has been completed with a bra with high wearing comfort and high comfort. That is, the present invention is as follows.

[Effect of invention]

The present invention provides an underwear and a bra, which can reduce the friction between the cup portion of the bra body and the skin by wearing the underwear covering the breast on the inner side of the bra, and reduce the shaking of the chest without increasing the wearing pressure Comfortable. Moreover, according to the present invention, the reduction in the feeling of rubbing when the size of the cup is larger is particularly obvious.

Hereinafter, a typical example of the present invention will be described in detail. One aspect of the present disclosure provides an undergarment provided with a belt portion on the breast covering portion and the upper and lower ends of the back.

Referring to FIGS. 1 and 2, it can be seen that the underwear 1 of one aspect of the present invention includes: a breast covering part 2; a back part 3, which extends from both sides of the breast covering part 2 (that is, the wearer’s rib side) to the back side; and The belt portion 4 is connected to the upper and lower ends of the breast covering portion 2 and the back portion 3.

In the underwear 1 of the present disclosure, it is assumed that the breast covering portion 2 is received in the wearer's breast. It is also assumed that the back 3 is worn so that the side of the wearer covers the back. The belt portion 4 refers to a portion of the gray fabric adjacent to the breast covering portion 2 and the back portion 3 that is disposed in the circumferential direction of the underwear 1 and has a higher tensile stress in the longitudinal direction than the breast covering portion 2 and the back portion 3. (However, except for the sewing part, embroidery part, etc., where the tensile stress at the point is high), the point where the tensile stress in the longitudinal direction changes (from the point where the tensile stress at the breast covering part 2 and the back part 3 becomes high) It becomes the boundary between the belt part 4 and the breast covering part 2 and the back part 3. 6 and 7 show the state of wearing the underwear 1 of this embodiment. FIG. 6 is a diagram showing the front side of the wearer, and FIG. 7 is a diagram showing the back side.

In the present disclosure, the “horizontal direction” (for example, the lateral direction of the breast covering portion 2) referred to the underwear 1 is the arrangement direction of the two cups, specifically, it means that the underwear 1 is placed flat, The direction of the straight line connecting the positions of the two breast peaks when the underwear 1 is placed such that the positions of the breast peaks of the two breast covering parts 2 are farthest from each other. In the present disclosure, the “longitudinal direction” of the underwear 1 means a direction perpendicular to the above-mentioned horizontal direction, and corresponds to the up and down direction of the body of the wearer.

In this disclosure, "breast peak position" means a position corresponding to the wearer's breast peak when wearing underwear (that is, a position corresponding to the wearer's nipple). In this disclosure, the "front centerline" and "back centerline" of the underwear 1 are lines that extend in the longitudinal direction of the underwear 1 by the midpoint of the line segment connecting the positions of the two breast peaks, and the front centerline is the front The upper part of the line, the back center line passes from the front center line to the left and right through the cup, and after passing through the back, the intersection of the lines extending from the left and right (that is, the point that is the farthest from the front center on the straight line distance) toward the vertical The line extending in the direction is the line on the back 3.

In the present disclosure, the circumference of the underwear 1 means the shortest length of a line drawn in a manner that returns from the front centerline through the back centerline to the front centerline. Moreover, if the underwear 1 has a length adjustment mechanism (for example, the length adjustment mechanism 5 in FIG. 3 mentioned later), it means the value of the state after adjusting the length adjustment mechanism so that the circumference may become the largest.

In the present disclosure, the underwear 1 has a length adjustment mechanism 5 on the back 3, which can be adjusted to match the circumference of the subject. Preferably, there is no length adjustment mechanism 5 and there is no longitudinal sewing thread in the circumferential direction. Since there is no length adjustment mechanism 5 and sewing thread in the longitudinal direction without discomfort during wearing, high comfort can be obtained.

In the breast covering part 2, it is preferable that the tensile stress at 50% of the lateral direction of the breast covering part in the third repeating extension test at 50% is 30 cN to 200 cN. Especially preferred is 50 cN to 150 cN. If the tensile stress of the breast covering 2 is 30 cN or more, it can be closely adhered to the chest without slack, and if it is 200 cN or less, the chest shape during wearing can be prevented and the feeling of restraint due to tightening can be suppressed .

In the back 3, the tensile stress at 50% of the transverse direction of the third breast covering part in the 50% repeated elongation test is set as S1, and the transverse stress 50% of the back 3 from the breast covering part back to the back When the tensile stress at the time is S2, it is preferably 2.0≦S2/S1≦5.0, and more preferably 2.5≦S2/S1≦4.5. When S2/S1 is 2.0 or more, the strength of the breast covering 2 and the back 3 behind the ribs of the breast covering is poor, and the breast covering 2 is easier to fit with the chest shape. If S2/S1 is 5.0 or less, it can be suppressed The sense of restraint caused by the tightness when wearing. In addition, in the back part 3, regions with different physical properties may be provided in a part by changing the structure of the knitted fabric or the like. If there are two or more regions with different physical properties on the back 3, the part with the largest area is set to S2 and the tensile stress is measured.

In the present disclosure, the underwear 1 is preferably provided with a belt portion 4 above and below the breast covering portion 2 and the back portion 3. By arranging the belt part 4, the tightness of the body and the underwear 1 can be improved. By improving the tightness, it can exert the effect of suppressing the shaking of the breast when the breast is shaking, and by wearing the underwear 1, in addition to preventing the rubbing of the breast and the bra, the rubbing of the breast and the underwear 1 can be further prevented, and Improve wearing comfort.

It is preferable to set the tensile stress at 30% in the longitudinal direction of the third breast covering portion in the 30% repeated elongation test to S4, and to set the tensile stress at 30% in the longitudinal direction of the belt portion 4 to S5. 2.0≦S5/S4≦4.5, more preferably 2.5≦S5/S4≦4.0. When S5/S4 is 2.0 or more, the belt part 4 fits the movement of the chest during movement without loosening, and is not easy to shift. When S5/S4 is 4.5 or less, it can suppress the tightening caused by wearing The sense of Leshu.

It is preferable that the tensile stress S3 at 50% of the transverse direction of the third time of the belt part at the 50% repeat elongation test of the belt part 100 is 100 cN to 350 cN. Especially preferred is 150 cN to 300 cN. If the tensile stress of the belt part 4 is 100 cN or more, it is not easily offset by fitting the chest movement during the movement without loosening, and if it is 350 cN or less, it can suppress the tightening caused by wearing The sense of Leshu.

The belt portion 4 is preferably arranged across the width of 1.0 to 5.0 cm from the longitudinal end of the breast covering portion 2. The above width is more preferably 1.0 to 4.0 cm. The above width can be arbitrarily designed. If the width is 1.0 cm or more, the adhesion between the breast and the underwear 1 can be improved, and the wearing comfort due to the anti-vibration property and the prevention of rubbing can be improved. Also, if the width is 5.0 cm or less, excessive pressure can be suppressed, and wearing comfort can be improved.

The material of each member of the underwear 1 of the present disclosure is not particularly limited, and synthetic fibers such as polyester-based fibers, polyamide-based fibers, polyurethane elastic fibers, rayon fibers, copper ammonia fibers, Cellulose fibers such as acetic acid and natural fibers such as cotton and hemp. In the present invention, it is effective to arrange fabrics having appropriate tensile properties on each member. As the knitting machine, single-strand circular knitting, double-strand circular knitting, Trico warp knitting, Raschel warp knitting, etc. can be used. The weaving specification of the knitting machine used is preferably 20-40 GG. In addition, as long as the sewing portion in the longitudinal direction is not provided in the circumferential direction, a forming circular knitting machine or a forming warp knitting machine can be suitably used.

As the yarn used for grey cloth, it can be composed of monofilament or multifilament. In multifilament yarns, it can contain matting agents such as titanium dioxide, stabilizers such as phosphoric acid, ultraviolet absorbers such as hydroxybenzophenone derivatives, crystal nucleating agents such as talc, lubricants such as Aerosil, and hindered phenol derivatives Antioxidants, flame retardants, antistatic agents, pigments, fluorescent whitening agents, infrared absorbers, defoamers, etc.

The total fineness of the cloth material constituting each member of the underwear 1 of the present disclosure can be a range generally used in clothing and the like. However, from the viewpoint of strength and softness, the total fineness is preferably about 22 to 310 dtex.

The basis weight of the fabric of each member of the underwear 1 used in the present disclosure is not particularly limited, but is preferably about 50 to 300 g/m ² .

The underwear 1 of the present disclosure may be worn on the inner side of the bra (that is, on the wearer's side) differently from the bra, or the underwear 1 and the bra body may be worn integrally, for example, by sewing. Preferably, it is worn in a state where the lower part of the bra body and the lower part of the underwear 1 are stitched together, and more preferably, the lower part of the front part of the brassiere (i.e., a brassiere in general) in order not to hinder the expansion and contraction of the back part 3 of the brassiere body (Bottom part) and the belt part 4 of the lower part of the underwear 1 are sewed and they are worn integrally. The means of integration is not particularly limited, and in addition to stitching, integration by thermal compression, etc. in which a stretchable band or the like is sandwiched between the bra and the underwear 1 may be performed.

The underwear 1 of the present disclosure can also be used by sewing the shoulder strap portion to the body after sewing the body.

The underwear 1 of the present disclosure is used in conjunction with a bra. By wearing on the inner side of the bra, the friction between the cup portion of the bra body and the skin of the chest during the wearing action can be reduced, thereby providing high comfort. During this wearing, the bra used in conjunction with the underwear 1 is not particularly limited, and even any bra can obtain the same effect. Preferably, it is used in combination with a bra with high anti-vibration (when the shaking value is less than 0.3 in the wearing test described later), in addition to comfort, anti-vibration effect can be obtained, so high wearing can be obtained Comfort.

The underwear 1 of the present disclosure is extremely excellent in suppressing the friction between the cup of the brassiere body and the chest when the chest is shaken when the chest is shaken when used together with the brassiere. To evaluate this effect, the following methods can be used. In addition, as an index of the vibration resistance of the bra body, the amount of sway of the chest is also measured simultaneously. After the height of 160 cm±8 cm and the value of (peak breast size-bottom breast size) was 17.5 cm or more, 5 subjects were wearing underwear 1 and wearing a bra on it, at a speed of 4.5 km/ on a treadmill h. At a step of 140 steps per minute, jog with one foot off the ground when landing. At this time, a reflective ball with a diameter of 1.3 cm was preliminarily attached to the clavicle and the breast peak, and the reflective ball was photographed with two high-speed cameras for 20 seconds. As an index of the swaying of the chest when the swaying of the clavicle becomes 7.0 cm, the three directions of the horizontal (X), horizontal (Y) and depth (Z) are calculated (the sway of the breast peak)-(clavicle (Shake) (cm) in 20 seconds (average of maximum value)-(average of minimum value) (cm). Here, the X direction means the lateral direction of the bra, and the Y direction and the Z direction are perpendicular to the X direction, respectively. The maximum value among the three directions is taken as the shaking (cm) when wearing, and the value (cm) of (peak breast size-bottom breast size) is divided as the shaking value. If the shaking value is 0.3 or less, the shaking is small, which is advantageous. The shaking value is preferably 0.25 or less, and more preferably 0.2 or less. The smaller the sloshing value, the better, but from the viewpoint of avoiding excessive pressure and easily obtaining a good wearing feeling, for example, it is preferably 0.03 or more, and more preferably 0.05 or more. [Example]

Hereinafter, the present invention will be specifically described by examples. Of course, the invention is not limited to these embodiments. In addition, the underwear obtained in Examples and Comparative Examples was evaluated by the following method.
