Abstract

PROBLEM TO BE SOLVED: To solve the problem extremely difficult to be solved that there is a tendency to worsen the wear feeling, in the case where the shoulder strings for a brassiere are made with a tape-form fabric having a uniform power and the compensation effect on the busts is increased, the shoulder strings are pulled up and the pressure feeling to the shoulders becomes stronger, on the contrary, in the case where the pressure to the shoulders are loosened in order to improve the wear feeling, the silhouette of the busts is worsened with difficult attainment of the good balance between the compensation effect (silhouette) and the wear feeling. SOLUTION: In a brassiere that is composed of a couple of the cup parts 2, the lower middle fabric 5, a couple of the side fabrics 7, and a couple of the shoulder string fabrics 11, the fabric for shoulder strings 11 and the side part fabrics 7 are continuously formed by knitting the low stretching knitted fabric parts and the high stretching knitted fabric parts and suitably arranging them every needed width dimension for each part. Thus, the shape retention of the cup parts is maintained, the pressure feelings to individual parts such as sides, back and shoulders are reduced to remove the feebleness and the brassiere fabrics are given difference in their stretching power and the side fabrics 7 can play the role of the cushioning thereby causing no deviation of the cup positions, even when the body plays large bending and stretching motions with excellent wear feeling attained.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knitted fabric in which low-stretch and high-stretch fabric portions are continuously knitted to form a shoulder strap portion and side portions of a bra, and to maintain shape retention of a cup portion. The present invention relates to a bra that has a good feeling of wearing that eliminates the feeling of pressure on the shoulder straps and the sides.

[0002]

2. Description of the Related Art Heretofore, as a cloth for a shoulder strap of a bra, for example, a tape-shaped cloth having a uniform expansion / contraction power has been used. Fabric was switched and sewn.

[0003]

Therefore, when the shoulder strap portion is formed using a tape-like cloth having a uniform expansion and contraction ratio, the shoulder strap is lifted up in order to enhance the bust correction effect. There was a tendency that the feeling of pressure on the part became stronger and the feeling of wearing became worse. Conversely, if the feeling of tightness of the shoulder straps is relaxed to improve the feeling of wearing, there is a disadvantage that the feeling of bust silhouette deteriorates. Thus, it is extremely difficult to maintain the balance between the correction effect (silhouette) and the feeling of wearing. There was a drawback that it was difficult.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention requires a brassiere formed of a cup part 2, a lower center cloth 5, a side cloth 7, and a shoulder strap cloth 11. The warp knitted fabric obtained by appropriately knitting and arranging a low elasticity knitted fabric portion and a high elasticity knitted fabric portion for each dimension width to form the shoulder strap fabric 11 and the side portion fabric 7. As a result, the extra stitching process for switching sewing is labor-saving as in the past, and since there is no bulky seam due to switching sewing, the touch is greatly improved, and the side of the breast is further secured. It is designed to provide excellent brassiere when worn.

[0005]

1 and 2, 1 is a brassiere, 2 is a cup part, 5 is a lower central cloth provided below the cup parts 2 and 2, and 7 and 7 are side cloths, respectively. , 1
Reference numerals 0 and 10 denote shoulder strap portions, 11 denotes a cloth for shoulder straps, and 12 and 1 respectively.
Reference numeral 2 denotes a tape cloth for covering the cloth 11 for the shoulder strap, and the tape cloth 12 is folded in half in the longitudinal direction, and covers both side edges of the cloth 11 for the shoulder string by well-known means. I try to wear it.

It is preferable to use a warp knitted fabric, such as a Russell knitted fabric, which is highly stretchable in both the warp and weft directions, and preferably use a single fabric. The warp direction, that is, the knitting direction of the warp knitted fabric is used as the warp knitted fabric so that the knitting direction of the warp knitted fabric substantially coincides with the vertical direction of the bra (the direction perpendicular to the chest circumference), and the weft direction of the warp knitted fabric is the chest circumference of the brassiere. It is made to substantially match with.

The use of the cloth for the shoulder strap cloth 11 is as follows.
Similarly, a warp knitted fabric such as a Russell knitted fabric having a high elasticity in both the warp and weft directions is preferable, and a single fabric is preferably used. In this case, the warp direction of the warp knitted fabric, that is, the knitting direction of the warp knitted fabric is shouldered. The width direction of the cord 10 is made to substantially match, and the weft direction of the warp knitted fabric is made to substantially match with the longitudinal direction of the shoulder cord 10.

The lower central fabric 5 is made of a single fabric of warp knitted fabric, and is formed of a knitted fabric portion L having low elasticity and high power. Further, the side portion fabric 7 is also a single fabric using warp knit fabric, and in a knitted fabric having a constant fabric width, fabrics having different expansion / contraction power in the knitting direction for each required dimension width are continuously knitted. A knitted fabric portion L having low elasticity and high power is arranged at a position extending from the position of the portion 15 below the cup portion 2 to the portion 16 close to the cup portion 2. From the position of the part 16 on the lower side to the part 1 on the back side
At a position reaching 7, a knitted fabric portion H having high elasticity and low power is arranged.

That is, from the position of the lower central cloth 5 and the portion 15 below the cup portion 2 to the portion 16
Are formed by the knitted fabric portion L having low elasticity and high power, thereby keeping the shape of the cup portion and preventing the cup portion from being tightened.

Further, a knitted fabric portion H having high elasticity and low power is arranged at a position from the position of the portion 16 to the portion 17 on the back side of the side portion cloth 7, so that the body is bent and stretched sharply. Even in such a case, the knitted fabric portion H serves as a cushion, so that the cup portion is not forcibly pulled to the side portion side, and the shape retention of the cup portion is reliably maintained.

The lower central cloth 5 and the side cloth 7
For the warp knitted fabric used for the low stretch knitted fabric portion L, a plurality of (for example, two to three) single yarns made of 100 to 300 denier polyurethane elastic fibers (for example, 210 denier) are drawn. Aligned and used as warp insertion yarns; furthermore, single yarn yarns of 100 to 300 denier polyurethane elastic fibers (for example, 210 denier) are used as weft insertion yarns, and 50 to 150 denier synthetic fibers such as nylon. A yarn (for example, 70 denier) is used as a yarn for closed knitting, and the knitting structure is knitted by appropriately inserting the elastic fibers in the warp and weft directions based on net-like knitting. .

For the use of the knitted fabric portion H, which has high elasticity and low power, for the side portion cloth 7, a single yarn yarn of 100 to 300 denier polyurethane-based elastic fiber (for example, 210 denier) is used as a warp insertion yarn. A single yarn made of 100 to 300 denier polyurethane elastic fiber (for example, 210 denier) is used as a weft insertion yarn, and a 50 to 150 denier synthetic fiber yarn such as nylon (for example, 70 denier) is used. ) Is used as a thread for closed knitting, and the knitting structure is knitted by appropriately inserting the elastic fibers in the warp and weft directions based on net-like knitting.

As shown in FIG. 2, the lower central fabric 5 is formed of a knitted fabric portion L having low elasticity and high power as described above. From the position of the portion 15 below the cup portion 2 to the portion 18 close to the cup portion 2 on the lower side of the side material 7
, A knitted fabric portion L having low elasticity and high power is arranged similarly to the above.

Further, a part 1 on the lower side of the side cloth 7
Knitted fabric portions H1, H2, and H3 having different powers are arranged at the portion from 8 to the portion 19, the portion from the portion 19 to the portion 20, and the portion from the portion 20 to the portion 17 on the back side. I have to do it.

That is, the stretchability and power of the knitted fabric portions H1, H2 and H3 are made to gradually increase as compared with the knitted fabric portion L, and the power is gradually reduced. As a result, the influence of the pulling force from the back side is reduced, and the stability of the side-side cloth 7 is improved by using the cloth with different power in stages (gradation type). Because it's gone
The configuration when the side part fabric 7 is worn becomes more beautiful, and the feeling of wearing is improved.

As shown in FIG. 3, the lower central fabric 5 is formed of a knitted fabric portion L having low elasticity and high power as described above. At a position from the position of the portion 15 below the cup portion 2 to the portion 23 close to the cup portion 2, a knitted fabric portion L having low elasticity and high power is arranged as described above.

Further, the above-mentioned part 23 to the back part 17
In the position reaching to, the knitted fabric portion H having high elasticity and low power and the knitted fabric portion L having low elasticity and high power are alternately arranged at appropriate required widths, so that the side portions are formed in the same manner as described above. The configuration when the cloth for use 7 is worn becomes more beautiful, and the feeling of wearing is improved.

According to the present invention, as described above, the side portion cloth 7 has different expansion / contraction power for each required dimension width in the knitting direction without switching and sewing several types of cloths having different expansion / contraction powers as in the related art. By using a material obtained by continuously knitting the fabric, switching sewing is not required, so that the sewing efficiency is improved.

By appropriately arranging the low-elasticity knitted fabric portion and the high-elasticity knitted fabric portion in sequence, the shape retention of the cup portion 2 is maintained, and compression of the side, back, and shoulder portions is performed. The feeling is reduced, the feeling of fatigue is eliminated, and the effect of cushioning is obtained through the difference in the expansion and contraction power of the fabric, and the displacement of the cup part is eliminated even when the body is severely bent and stretched. The effect is obtained.

Next, in FIG. 4, reference numeral 30 denotes a top portion of the cup portion 2, which is a connection and sewn portion between the front and back fabrics of the cup portion and the fabric 11 for the shoulder strap, and 31 is a side portion on the back body side. The connection and sewn portion between the cloth 7 and the cloth 11 for the shoulder strap.

The cloth 11 for the shoulder straps is
From the apex portion 30 to the back body portion 31 of the knitted fabric portion K with low elasticity and high power, the knitted fabric portion J with high elasticity and low power, and the knitted fabric with low elasticity and strong power The parts K are respectively arranged and formed.

Accordingly, by forming the shoulder strap cloth 11 at the base of the top part 30 of the cup part 2 and at the base of the rear part 31 by the knitted fabric part K having low elasticity and high power, the body flexes and stretches. Sometimes the top 30 of the cup portion 2 and the back side cloth 7 are not pulled, and the middle part of the shoulder strap cloth 11 is composed of a highly elastic and low power knitted fabric portion J. By doing so, the pressing force on the shoulder and the back is reduced, and a good wearing feeling is obtained.

The warp knitted fabric used for the low elasticity knitted fabric portion K of the above-mentioned shoulder strap cloth 11 is 100 to 3 yarns.
00 denier polyurethane elastic fiber (for example, 210
Denier) single yarn (for example, two or three)
Aligned and used as warp insertion yarns;
00 denier polyurethane elastic fiber (for example, 210
Denier) is used as a weft insertion yarn, and 50 to 150 denier nylon or other synthetic fiber yarn (for example, 70 denier) is used as a closed knitting yarn. The knitting is performed by appropriately inserting the elastic fibers in the warp and weft directions based on net-like knitting.

As for the use of yarn of the knitted fabric portion J having high elasticity and low power, a single yarn made of 100 to 300 denier polyurethane elastic fiber (for example, 210 denier) is used as a warp insertion yarn. 100 to 3
00 denier polyurethane elastic fiber (for example, 210
Denier) is used as a weft insertion yarn, and 50 to 150 denier nylon or other synthetic fiber yarn (for example, 70 denier) is used as a closed knitting yarn. The knitting is performed by appropriately inserting the elastic fibers in the warp and weft directions based on net-like knitting.

The cloth for shoulder strap 11 shown in FIG. 5 includes a portion 30 at the top of the cup portion 2 and a portion 3 on the back body side.
The knitted fabric portion K having low elasticity and high power is arranged at each position close to 1 and the knitted fabric portion J1 having high elasticity and small power is located at an intermediate position between both knitted fabric portions K and K. J
2, J3, J2 and J1 are arranged respectively.

That is, regarding the stretchability and power at the knitted fabric portions J1, J2 and J3, the knitted fabric portion K
In comparison with the above, fabrics having different powers are used so that the elasticity increases stepwise (gradation type), and the power decreases stepwise.

Therefore, the top portion 30 of the cup portion 2 and the back side cloth 7 are not pulled when the body bends and stretches, and the middle portion of the shoulder strap cloth 11 is highly elastic and flexible. By forming the knitted fabric portion having a small power in a stepwise manner, the top portion 30 of the cup portion 2 can be used when the body bends and stretches.
In addition, the influence of the pulling force on the side fabric 7 on the back side is reduced, and the pressing force on the shoulder and the back is reduced, so that a good wearing feeling can be obtained.

The stretch ratio of the low-stretch knitted fabric portion L, ie, the low-stretch knitted fabric portions L1 and L2, is, for example, the warp direction (knitting of the knitted fabric) under a load of 2.25 kg. Direction) is preferably in the range of 150 to 250%, and the extension in the weft direction is in the range of 150 to 250%.
Further, the load value in the warp direction at 80% elongation is 2000 to 700
It is preferable that the load value is 0 g and the load value in the weft direction is 2000 to 7000 g.

The stretch ratio of the knitted fabric portion H having high elasticity and small power, that is, the high elasticity knitted fabric portions H1 and H2 is, for example, in the warp direction (knitting of the knitted fabric at a load of 2.25 kg). Direction) of 150-250%,
Further, the elongation ratio in the weft direction is preferably in the range of 200 to 400%, and the load value in the warp direction at the time of 80% elongation is preferably 2000 to 7%.
000g and the load value in the weft direction is 1000-2000
The range of g is preferred.

For each of the above-mentioned stretching ratios and load values, if the stretching ratio or the load value is not more than the upper limit or the lower limit of the respective ranges, the feeling of pressure on the breast becomes strong, or the flow to the side of the breast is reduced. There are drawbacks such as a reduced feeling of wearing, such as inability to reliably support, which is not preferable.

The above-described elongation ratio and load value can be obtained from a stress-strain curve (stress-strain curve) by a known means in the related art. In the present invention, the following methods were used. That is, as the elongation ratio S under a load of 2.25 kg, a sample having a width of 2.5 cm and an effective length for measurement of 15 cm was used, and the third time of 2.25 kg at the time of repeated measurement up to a load of 2.25 kg It is a measurement of the elongation under load. As a method of indicating the above-mentioned extension rate, when the extension length after extension is L and the original dimension is K, the extension rate S is
(L / K) × 100 (%). The load value at the time of 80% elongation means that a sample having a width of 2.5 cm and an effective length for measurement of 15 cm is used.
The load value at the time of the third 80% elongation at the time of repeated measurement is measured.

In the present invention, fabrics having different expansion / contraction power in the knitting direction for each required dimensional width are continuously used without changing and sewing several types of fabrics having different expansion / contraction powers as in the related art. By appropriately using the knitted fabric, the switching sewing is not required, so that the sewing efficiency is improved, and since there is no seam for seaming, the sewing is not bulky and the feel and wearing feeling are improved.

Further, by appropriately arranging a low elasticity knitted fabric portion and a high elasticity knitted fabric portion as the side material 7 and the shoulder material 11 in order, the shape retention of the cup portion 2 is maintained. The feeling of pressure on each part of the side, back and shoulders is reduced,
In addition, the feeling of fatigue is eliminated, and the effect of playing a role of a cushion is obtained through the difference in expansion and contraction of the cloth. The effect of eliminating the displacement of the cup portion even when the body is severely bent and stretched is obtained.

[0034]

As described above, the present invention relates to a brassiere formed of the cup part 2, the lower central cloth 5, the side cloth 7, and the shoulder strap cloth 11 having a low elasticity knitted fabric portion for each required dimension width. By forming the above-mentioned cloth 11 for the shoulder strap and the cloth 7 for the side part with a warp knitted fabric obtained by appropriately knitting and arranging a highly elastic knitted fabric portion, the shape retention of the cup portion 2 is maintained. In addition, the feeling of pressure on each part of the side, back and shoulders is reduced, the feeling of fatigue is eliminated, the difference in expansion / contraction power is provided in the cloth, and the side cloth 7 serves as a cushion.
This eliminates displacement of the cup part even when the body is intensely flexing and stretching, and maintains the balance between the correction effect (silhouette effect) and the feeling of wearing in an extremely good state by appropriately holding the pressure on the shoulder straps It is possible to obtain a bra with excellent wearing feeling.
