DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brassiere fabric for the side portion of a brassier, which is formed of a knitted fabric in which a low-stretch and a high-stretch fabric portion is continuously knitted, while maintaining the shape of the cup portion.
The present invention relates to a bra that has a good wearing feeling so as to eliminate a feeling of pressure on the side.

[0002]

2. Description of the Related Art Conventionally, in order to stabilize a cup portion, a fabric having a high power is sewn to a portion adjacent to the cup portion to prevent the flow of the breast side portion. Further, the cloth with the lower power is switched and sewn adjacent to the part where the cloth with the higher power is located so as to reduce the feeling of pressure on the side parts.

[0003]

Therefore, an extra sewing step is required to switch and sew cloths of different powers as side cloths. Further, the switch sewn section has a large seam, and thus has a soft touch. Poor and had drawbacks such as reduced wearing feeling.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a brassiere formed of a cup part 2, a lower central cloth 5, a side cloth 7, and a shoulder strap 10 having a suitably small width. The side knitted fabric 7 is formed from a warp knitted fabric formed by continuously knitting the stretchable knitted fabric portion L and the high stretchable knitted fabric portion H. The extra stitching process is labor-saving, and there is no seam bulk due to switching sewing, so the feel is extremely improved, and the breast side can be reliably supported, resulting in an excellent bra when wearing. It is intended to be.

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
0 and 10 are shoulder straps, respectively. It is preferable to use a warp knitted fabric such as a Russell knitted fabric which is highly elastic in both the warp and weft directions. A vertical fabric is used so that the vertical direction coincides with the vertical direction of the bra (the direction perpendicular to the chest circumference).

That is, the side portion cloth 7 is provided at a portion adjacent to the cup portion 2 with a low elasticity and high power knitted fabric portion L.
In addition, the knitted fabric portions H having high elasticity and low power are sequentially arranged for each appropriate fabric width, and are formed by the warp knitted fabric 8 which is continuously knitted. The embodiment of the side cloth 7 shown in FIG. 1 includes a knitted fabric portion L1 having low elasticity and high power, a knitted fabric portion H2 having high elasticity and small power, and a knitting material having low elasticity and strong power. The ground portion L2 and the knitted fabric portion H2 having high elasticity and low power are formed by a warp knitted fabric 8 made of a single knitted fabric continuously knitted. Further, the side cloth 7 in FIG. 2 shows another embodiment, in which a knitted fabric portion L1 having low elasticity and high power and a knitted fabric portion H1 having high elasticity and small power are continuously knitted. The warp knitted fabric 8 is made of a single knitted fabric.

The warp knitted fabric used for the side portion fabric 7 has a low elasticity and high power knitted fabric portion L, that is, a low elasticity knitted fabric portion L1 and L2 has 10 yarns.
Plural single yarns (for example, 2 to 200 denier polyurethane elastic fibers (for example, 140 denier))
3) Aligned and used as warp insertion yarns;
Up to 120 denier polyurethane-based elastic fiber (for example, 8
(0 denier) as a weft insertion yarn, and 20-80 denier synthetic fiber yarn such as nylon (for example, 40 denier) as a closed knitting yarn. On the basis of net-shaped knitting, knitting is performed by appropriately inserting the elastic fibers in the warp and weft directions.

The knitted fabric portion H having high elasticity and small power, that is, the yarn used for the high elasticity knitted fabric portions H1 and H2, is made of a single yarn of 100 to 200 denier polyurethane elastic fiber (for example, 140 denier). The yarn is used as a warp insertion yarn, and a single yarn of 40 to 120 denier polyurethane elastic fiber (for example, 80 denier) is used as a weft insertion yarn, and a 20 to 80 denier nylon or the like is synthesized. Fiber yarn (for example, 40 denier)
Is used as a thread for closing knitting, and as a knitting structure,
The knitting is performed by appropriately inserting the elastic fibers in the warp and weft directions based on net-like knitting.

The extension ratio of the low-stretch knitted fabric portion L, that is, the high-strength knitted fabric portion L1, 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), the elongation in the weft direction is preferably in the range of 100 to 200%, and the elongation in the latitudinal direction is preferably in the range of 100 to 200%.
g, the load value in the weft direction is preferably in the range of 1500 to 2500 g.

The stretch ratio of the high-stretch knitted fabric portion H having a small power, that is, the high-stretch knitted fabric portions H1 and H2 is, for example, the warp direction (knitting of a knitted fabric) under a load of 2.25 kg. Direction) is 200 ~ 300%,
The stretch ratio in the weft direction is preferably in the range of 100 to 200%,
Furthermore, the load value in the meridian direction at the time of 80% load is 500 to 1000
g, the load value in the weft direction is preferably in the range of 1000 to 2000 g.

For each of the above-mentioned stretching ratios and load values, when 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 is increased 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.

Further, the above-mentioned elongation ratio and load value are obtained by a stress-strain curve (stress-strain curve) by a conventional well-known means. 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.
