Description
Technical Field
The present invention relates to an undergarment and a brassiere that suppress chest movement during movement in a worn state. More particularly, the present invention relates to an undergarment and an undergarment integrated with the undergarment, which are used in combination with a brassiere to reduce the feeling of chest friction (japanese: wipe れ) and pain associated with the friction caused by movement during operation, thereby providing high comfort and having an effect of suppressing chest movement during operation in a worn state.
Background
One of the main purposes of the brassiere is to adjust the shape of the chest to be beautiful, and the suppression of the chest sloshing during exercise is also one of the great effects of the brassiere. However, in most cases, even if the brassiere is worn, the chest still largely shakes while walking or running. Particularly, when the chest is large in size, the degree of the shaking becomes extremely large, which not only causes a feeling of discomfort and a burden on the wearer, but also causes the chest to sag. As a method of alleviating the sloshing, this method is effective in wearing a brassiere having a strong wearing pressure, but it causes a significant deterioration in wearing comfort. Further, the degree of chest movement is further increased during exercise, and this hinders the wearer from performing movements and puts a burden on the wearer, which is more significant. Therefore, many sports bras have been developed as bras for reducing the chest sloshing during exercise (patent documents 1 and 2).
However, in the case of the sports brassiere, the cover area is increased to suppress the play during the movement, and the design for covering the cleavage is increased. Therefore, the wearing pressure is high due to a large covering area when the wearer wears the garment, and the comfort is not satisfactory.
In the technique described in patent document 3, the secondary wing portions are disposed on the brassiere body in regions from the cup portions to the wing portions. The flap is made of a grey fabric having a tensile stress different from that of the fabric of the brassiere main body, and by arranging the flap, a force of tension acts from the joint portion of the flap portion in the cup portion toward the flap portion by the difference in tensile stress between the main body fabric and the flap when worn, and a vibration damping effect can be exhibited.
In the brassiere described above, although the cleavage is largely opened by the effect of the flaps, the movement can be suppressed without impairing the comfort. However, the subjective evaluation of the vibration damping performance and the comfort when wearing the brassiere is higher than that of a general brassiere, and the sway value is also lower, but the brassiere may feel a little unnatural in terms of comfort.
In the technique described in patent document 4, a clothing material has been developed which covers the shoulder, abdomen, and back and reinforces the periphery of the front surface around the back surface and the chest wrapping portion by a pressing portion, thereby making it possible to keep a good posture when worn.
In the technique described in patent document 5, by wearing a cloth having an opening portion at the upper opening portion, the lower opening portion, and the armhole portion, which is formed in a tubular shape, on the back surface of the brassiere, it is possible to improve a feeling of discomfort due to friction or the like generated between the chest and the brassiere when worn.
In the above-described underwear, although the uncomfortable feeling due to friction or the like of such a degree as to wear the underwear on the inner side of the brassiere can be reduced, it is considered that the underwear may also operate together with the movement of the brassiere, and a sufficient friction suppression effect cannot be obtained. Further, it is conceivable that the present effect cannot obtain a sufficient suppression effect for the shaking of the chest which increases in proportion to the size of the chest.

Disclosure of Invention
Problems to be solved by the invention
Accordingly, an object of the present invention is to provide an undergarment and a brassiere having an excellent vibration damping effect, which is an effect of reducing the chest vibration during exercise, and to provide an undergarment and a brassiere having an excellent comfort in addition to vibration damping.
Means for solving the problems
The present inventors found out by measurements with accelerometers that: in a brassiere like the brassiere disclosed in patent document 3, in which the entire breast portion is prevented from moving, the breast portion also moves finely in the three-dimensional direction. In a product that suppresses the entire chest from shaking in terms of acceleration, the chest can be suppressed from shaking to a large extent, but acceleration due to minute vibration is generated in all directions, and the chest always receives an impact due to acceleration. Therefore, the breast finely moves in the cup, and friction with the cup occurs, and the skin surface of the breast generates friction on the surface of the cup. This is considered to be a cause of the feeling of unnaturalness (particularly, feeling of skin friction on the chest and pain due to friction during movement) although the wobbling during wearing is suppressed. Therefore, in order to further improve the wearing comfort, it is considered necessary to improve the friction between the cups and the chest surface in the cups (Japanese: rubbing れ), and to reduce the feeling of friction and the pain caused by the friction.
The present inventors have made intensive studies to solve the above problems and repeated experiments, and as a result, have found that the present invention can provide a brassiere in which: through the inboard underwear of dressing at the brassiere, can alleviate the friction of the cup portion and the skin of brassiere main part, and can reduce rocking of chest to can not improve and dress pressure, the travelling comfort is higher. Namely, the present invention is as follows.

Detailed Description
An example of a typical embodiment of the present invention is described in detail below.
One aspect of the present invention provides an undergarment having belt parts at a chest covering part, a back body part, and upper and lower ends.
Referring to fig. 1 and 2, an undergarment 1 according to one embodiment of the present invention includes a chest cover 2, a back body 3 extending from the armpits of the chest cover 2 (i.e., the underarm side of the wearer) to the back, and belt portions 4 connected to the chest cover 2 and the back body 3 at the upper and lower ends.
In the undergarment 1 of the invention, it is envisaged that the chest covering portion 2 receives the wearer's breasts. It is also assumed that the back body portion 3 is worn so as to cover the back surface from the side surface of the wearer. The belt portion 4 is a raw fabric portion that is disposed adjacent to the chest covering portion 2 and the back body portion 3 in a circumferential band of the undergarment 1 and has a higher tensile stress in the longitudinal direction than the chest covering portion 2 and the back body portion 3 (except for a portion having a higher tensile stress at individual points such as a sewn portion and an embroidered portion), and a point at which the longitudinal tensile stress changes (a point at which the tensile stress increases from the chest covering portion 2 and the back body portion 3) is a boundary line between the belt portion 4 and the chest covering portion 2 and the back body portion 3.
Fig. 6 and 7 show a state in which the undergarment 1 of the present embodiment is worn. Fig. 6 is a view showing the front side of the wearer, and fig. 7 is a view showing the back side.
In the present invention, the "lateral direction" referred to with respect to the undergarment 1 (for example, the lateral direction of the breast covering portions 2) means the arrangement direction of the two cups, and specifically means the extending direction of a straight line connecting the positions corresponding to the two areolas when the undergarment 1 is placed so that the positions corresponding to the areolas of the two breast covering portions 2 are farthest from each other in a state where the undergarment 1 is laid flat. In the present invention, the "longitudinal direction" of the undergarment 1 means a direction perpendicular to the above-described lateral direction, and corresponds to the vertical direction of the wearer's body.
In the present invention, the "areola corresponding position" refers to a position corresponding to an areola of a wearer (i.e., a position corresponding to a nipple of the wearer) when the undergarment is worn. In the present invention, "front center line" and "back center line" of the undergarment 1 are lines extending in the longitudinal direction of the undergarment 1 through the midpoints of line segments connecting the corresponding positions of the two areolas, respectively, the front center line is a line located at the front portion of the chest, and the back center line is a line extending in the longitudinal direction at the intersection point of lines extending from left and right after passing through the cup portions from the front center line to left and right and passing through the back portion (i.e., the point farthest from the front center in the straight-line distance), and is a line located at the back portion 3.
In the present invention, the circumferential length of the undergarment 1 is the shortest length of a line drawn from the front center line through the back center line back to the front center line in the main body. When the underwear 1 includes a length adjustment mechanism (for example, a length adjustment mechanism 5 in fig. 3 described later), the value is a value in a state where the length adjustment mechanism is adjusted so that the circumferential length is maximized.
In the present invention, the undergarment 1 has a length adjustment mechanism 5 in the back body portion 3, and the length can be adjusted according to the circumference of the subject. Preferably, there is no length adjustment means 5 and no longitudinal sewing thread in the circumferential direction. Since the length adjusting mechanism 5 and the longitudinal sewing thread are not provided, the wearer does not feel unnatural when wearing the garment, and high comfort can be obtained.
In the chest covering part 2, the tensile stress when the chest covering part is elongated 50% in the lateral direction 3 rd time in the elongation test of repeating the elongation 50% is preferably 30cN to 200 cN. Particularly preferably 50cN to 150 cN. When the tensile stress of the chest covering portion 2 is 30cN or more, the chest covering portion can be closely attached to the chest without being loosened, and when the tensile stress is 200cN or less, the chest can be prevented from being deformed during wearing and the tight feeling due to the binding can be suppressed.
In the rear body 3, the tensile stress at the time of 3 rd elongation of the chest covering portion by 50% in the lateral direction in the elongation test of repeating 50% elongation is set to S1, and the tensile stress at the time of 3 rd elongation of the rear body 3 from the armpit of the chest covering portion to the back surface by 50% in the lateral direction is set to S2, in this case, it is preferably 2.0. ltoreq.s 2/S1. ltoreq.5.0, and more preferably 2.5. ltoreq.s 2/S1. ltoreq.4.5. When S2/S1 is 2.0 or more, there is an energy difference (difference of パワー in japanese) between the chest cover 2 and the rear body 3 under the armpit of the chest cover, and the chest cover 2 fits more easily to the shape of the chest, and when S2/S1 is 5.0 or less, the tight feeling due to the restraint during wearing can be suppressed.
In the rear body portion 3, regions having different physical properties may be locally provided by changing the weave of the fabric or the like. When two or more types of regions having different physical properties are present in the rear body portion 3, the portion having the largest area is designated as S2, and the tensile stress is measured.
In the present invention, the band portions 4 are preferably disposed in the upper and lower parts of the chest covering portion 2 and in the upper and lower parts of the back portion 3 of the undergarment 1. By arranging the band portion 4, the fit between the body and the undergarment 1 can be improved. Since the fit degree is improved, the effect of suppressing the swing of the chest when the chest is swung can be exerted, and the friction between the chest and the brassiere can be prevented by wearing the underwear 1, and in addition, the friction between the chest and the underwear 1 can be further prevented, thereby improving the wearing comfort.
In the case where the tensile stress at the time of elongating 30% in the longitudinal direction of the chest covering part 3 times in the elongation test of repeating 30% elongation is set to S4 and the tensile stress at the time of elongating 30% in the longitudinal direction of the belt part 4 3 times is set to S5, in this case, it is preferably 2.0. ltoreq.s 5/S4. ltoreq.4.5, more preferably 2.5. ltoreq.s 5/S4. ltoreq.4.0. When S5/S4 is 2.0 or more, the band portion 4 can fit against the chest movement during operation without slackening and is less likely to be displaced, and when S5/S4 is 4.5 or less, the tight feeling due to the restraint during wearing can be suppressed.
In the tape portion 4, the tensile stress S3 when the tape portion is elongated 50% in the transverse direction at the 3 rd time in the elongation test of repeating 50% elongation is preferably 100cN to 350 cN. Particularly preferably 150cN to 300 cN. When the tensile stress of the band portion 4 is 100cN or more, the band portion can be attached to the chest during movement without being loosened and hardly deviated, and when the tensile stress of the band portion 4 is 350cN or less, the tight feeling due to the restraint during wearing can be suppressed.
Preferably, the belt portion 4 is disposed across a width of 1.0cm to 5.0cm from the longitudinal end of the chest covering portion 2. The width is more preferably 1.0cm to 4.0 cm. The width can be designed arbitrarily. If the width is 1.0cm or more, the fit between the chest and the underwear 1 can be improved, the vibration damping performance can be improved, and the wearing comfort can be improved by preventing friction. Further, if the width is 5.0cm or less, the feeling of excessive pressure can be suppressed, and therefore, the wearing comfort can be improved.
The material of each member of the undergarment 1 of the present invention is not particularly limited, and synthetic fibers such as polyester fiber and polyamide fiber, cellulose fibers such as polyurethane elastic fiber, rayon, cuprammonium fiber and acetate fiber, and natural fibers such as cotton and hemp can be suitably used. In the present invention, it is effective to arrange a fabric having appropriate tensile properties for each member.
As knitting machines, a single bed circular knitting machine (Japanese: シングル pills), a double bed circular knitting machine (Japanese: ダブル pills), a tricot knitting machine (Japanese: トリコット yarns), a raschel knitting machine (Japanese: ラッシェル yarns), and the like can be used. The knitting gauge of the knitting machine to be used is preferably 20GG to 40 GG. Further, a molding circular knitting machine or a molding warp knitting machine is suitably used in that the longitudinal sewn portion is not provided in the circumferential direction.
The yarn used for the raw fabric may be a single yarn or a double yarn. The composite yarn may contain a delustering agent such as titanium dioxide, a stabilizer such as phosphoric acid, an ultraviolet absorber such as a hydroxybenzophenone derivative, a crystal nucleating agent such as talc, a slipping agent such as fumed silica (AEROSIL), an antioxidant such as a hindered phenol derivative, a flame retardant, an antistatic agent, a pigment, a fluorescent whitening agent, an infrared absorber, an antifoaming agent, and the like.
The total fineness of the fabric materials constituting each member of the undergarment 1 of the present invention can be in a range generally used for clothes and the like. Among them, the total fineness is preferably about 22dtex to 310dtex from the viewpoint of strength and softness.
The basis weight of the fabric used for each member of the undergarment 1 of the present invention is not particularly limited, but is preferably about 50g/m2～300g/m2。
The undergarment 1 of the present invention may be worn on the inner side (i.e., the wearer side) of the brassiere independently of the brassiere, or the undergarment 1 and the brassiere body may be worn integrally by, for example, sewing. Preferably, the brassiere is worn in a state where the lower portion of the brassiere body and the lower portion of the underwear 1 are sewn together, and more preferably, the band 4 of the lower portion of the underwear 1 and the chest portion of the lower portion of the brassiere (i.e., the lower girth portion of the brassiere in general) are integrally worn in a state where they are sewn together by sewing, so as not to hinder the expansion and contraction of the rear body portion 3 of the brassiere body. The means for integration is not particularly limited, and integration may be achieved by sandwiching an elastic band or the like between the brassiere and the underwear 1 and thermocompression bonding, in addition to sewing.
The undergarment 1 of the present invention may be used by sewing the shoulder straps to the main body by sewing after the main body is manufactured.
The undergarment 1 of the present invention can reduce friction between the cup portions of the brassiere body and the skin of the chest when the undergarment is worn and is worn on the inner side of the brassiere, and can provide high comfort. The brassiere used in combination with the underwear 1 when the present invention is worn is not particularly limited, and any brassiere can provide the same effects. Preferably, by using a brassiere having high vibration damping properties (a brassiere having a sway value of less than 0.3 in a wear test described later), a vibration damping effect can be obtained in addition to comfort, and therefore, higher wearing comfort can be obtained.
The underwear 1 of the present invention is used in combination with a brassiere, and therefore, when the breast shakes during movement, the friction between the breast cups of the brassiere body and the breast is extremely well suppressed. To evaluate the effect, the following method can be used. In addition, as an index of the vibration damping performance of the brassiere body, the amount of breast sway was also measured at the same time.
After 5 examinees having a height of 160cm ± 8cm and a value (upper bust size-lower bust size) of 17.5cm or more were put on the underwear 1, the brassiere was put on the underwear 1, and the examinees were run on a treadmill at a speed of 4.5km/h and at a pace of 140 steps per minute so as to leave one foot off the ground when landing. At this time, reflective balls having a diameter of 1.3cm were attached to the clavicle part and the areola part in advance, and the reflective balls were photographed for 20 seconds by two high-speed cameras. As an index of thoracic movement during sprinting such that the movement of the clavicle portion was about 7.0cm, the average of the maximum values (the average of the maximum values) - (the average of the minimum values) (cm) of (areola movement) - (movement of the clavicle) (cm) in 20 seconds in each of the 3 directions of the lateral direction (X direction), the longitudinal direction (Y direction) and the cup depth direction (Z direction) was calculated. Herein, the X direction means a transverse direction of the brassiere, and the Y direction and the Z direction are perpendicular to the X direction, respectively. The maximum value among the values in the 3 directions was taken as a wobbling value (cm) at the time of wearing, and this value was divided by the value (cm) (upper bust size-lower bust size) to obtain a wobbling value. When the jitter value is 0.3 or less, the jitter is small, which is advantageous. The value of the jitter is preferably 0.25 or less, more preferably 0.2 or less. The smaller the value of the amount of the movement is, the more preferable the value is, from the viewpoint of avoiding excessive pressing and easily obtaining a good wearing feeling, for example, 0.03 or more, and more preferably 0.05 or more.
Examples
The present invention will be described in detail with reference to examples. Of course, the present invention is not limited thereto. Further, the underwear obtained in the examples and comparative examples were evaluated by the following methods.
(1) Measurement of longitudinal and transverse tensile stresses in individual blanks
The tensile stress of the stretch fabric was measured by the following method.
Size of the sample: length 100mm (excluding the grip)
Width of test piece: 25mm
A tensile testing machine: tensilon tensile tester (RTC-1210A made by ORIENTEC CORPORATION)
Initial load: 0.1N
Stretching speed: 300mm/min
Stretching length and measurement: the stretching was carried out at the same speed until 30% or 50%, and then the steel sheet was returned (recovered) to the original length, and the stretching and recovery were repeated 3 times under the above conditions to obtain the tensile stress value at the time of 30% or 50% stretching in the 3 rd pass.
In addition, in the case where a sample having a predetermined width cannot be obtained from a product, the width of the obtained sample is measured, and then the measured value is converted into a tensile stress at the predetermined width by the following equation.
The converted tensile stress [ cN ] ═ measurement value [ cN ] × 25[ mm ]/(width of obtained sample [ mm ])
In addition, when a sample having a predetermined length cannot be obtained from a product, the length of the obtained sample is measured, and then the elongation is set based on the length so as to have a predetermined elongation, and the measurement is performed.
(2) Shaking when wearing (sloshing value)
5 examinees who had a brassiere size D65 and a height of 160 cm. + -.8 cm (bust-bust) were put on underwear and brassiere, and the examinees were run on a treadmill at a speed of 4.5km/h and a step of 140 steps per minute in a manner of stepping off the ground with one foot. At this time, reflective balls having a diameter of 1.3cm were attached to the clavicle part and the areola part in advance, and the reflective balls were photographed for 20 seconds by two high-speed cameras (250 frames/SEC). The rocking of the clavicle part was about 7.0 cm. As an index of the chest movement during wearing, the maximum value (average value of maximum values) - (average value of minimum values) (cm) of (movement of areola) - (movement of clavicle) (cm) in 20 seconds was calculated, the maximum value among the values in the lateral direction (X direction), the longitudinal direction (Y direction), and the cup depth direction (Z direction) was set as the movement value (cm) during wearing, and the movement value was obtained by dividing the value by the value (cm) (upper bust-lower bust). The results of 5 subjects were averaged and calculated.
(3) Maximum wearing pressure
When wearing a brassiere and underwear, a sensor is inserted between the underwear and a wearer (between the wearer and the brassiere when wearing the brassiere alone) for a portion corresponding to a lower edge band portion of the back body portion, a central portion of the back body portion, a shoulder central portion of the shoulder band portion, a rear root portion of the shoulder strap portion, a portion above the cup, a portion below the armpit of the cup, and a portion below the cup to measure a wearing pressure, and a maximum value among the obtained values is taken as a maximum wearing pressure (hPa).
