Description

The present invention relates to the structure of a brassiere, particularly its back tape.

Various bras are known, but most of them are the left and right cup parts, the front cloth that connects the left and right cup parts and extends to the armpit side, and turns from both ends of the front cloth to the back. It consists of left and right back tapes, and left and right shoulder straps that connect the cup portion and the back tape. And said back tape cuts elastic knitted fabrics, such as a power net, into the desired shape long in the lengthwise direction (extension direction), for example, a trapezoid, and makes this into a main part using horizontally long, along the upper side and the lower side It was made by sewing a narrow elastic ribbon. For example, FIG. 5 is a cross-sectional view of the back tape, and FIG. 5A shows the back tape 1 with the upper side 1a and the lower side 1b folded, and the stretchable ribbon 2 overlapped and sewn on the folded part. ) Shows the top side 1a and the bottom side 1b of the back tape 1 which is folded in two so that the stretchable ribbon 3 can be covered with each other. Shown in Fig.

Therefore, the conventional brassiere requires the edge cleaning by sewing on the upper and lower edges of the back tape, the number of processes increases, and the upper and lower edges become thicker, so a step is generated between the main body made of power net, When wearing a brassiere, the upper and lower sides of the back tape bite into the human body due to its tension, leaving a so-called bra mark, giving an unpleasant feeling of pressure, and easily sweating, and can be seen through the top of a blouse, etc. There was a problem such as.

According to the present invention, the back tape of the brassiere is formed to have a uniform thickness to eliminate the difference in level between the upper and lower sides, and it is possible to simplify the brassiere manufacturing process by eliminating the need for edge trimming of the back tape. It is possible to set the elastic elasticity of the upper part, lower side part, and the middle part between them arbitrarily, so that the feeling of wearing is good, the bra mark is not formed by wearing, and the upper side and the lower side of the back tape can be seen through from the top of the outerwear. It is something to prevent.

The brassiere according to the present invention includes left and right cup parts, a front cloth that connects the left and right cup parts and extends to the underarm side, a back tape that rotates from both ends of the front cloth to the back, and the cup part and the back part. In a brassiere equipped with left and right shoulder straps that connect the tapes, the back tape is obtained by weaving while gradually changing the width without changing the total number of warps, and having elastic elasticity in the warp direction The woven tape has a wide side connected to the front cloth, and an ear on one side forms an upper side of the back tape and an ear on the other side forms a lower side of the back tape. And

That is, in the brassiere of the present invention, the upper side and the lower side of the back tape are constituted by ears on one side and ears on the other side of the woven fabric tape, respectively. Therefore, when assembling the brassiere, the upper side and the lower side of the back tape need not be sewn for finishing, and the assembly of the brassiere is facilitated accordingly. Further, the fabric tape has a stretch elasticity in the warp direction, and this stretch elasticity can be produced by mixing a warp with an elastic warp having rubber-like elasticity and a normal warp without rubber-like elasticity. The elastic elastic modulus can be set arbitrarily without changing the thickness of the fabric tape by setting the elastic warp mixing ratio, etc. Therefore, separate elastic tapes with different widths are sewn on the upper and lower sides of the back tape. This also makes it easy to assemble the brassiere. And since the thickness of a back tape becomes uniform, the wearing feeling of a brassiere becomes good, a bra mark is not made, and it does not see through from a jacket.

The above-mentioned woven tape is attached to a narrow tape loom with different heel spacing (density) up and down, and the above heel is moved up and down during weaving to widen the wing spacing, that is, the threading width. It can be manufactured by narrowing. The back tape of the brassiere is formed in a shape similar to a trapezoid having a long tape shape or a belt shape in the horizontal direction (chest circumference direction), a relatively wide width on the armpit side, and a relatively narrow width on the back side. The shape of the upper side and the lower side can be arbitrarily set, such as a straight line or a curve, by changing the speed of the vertical movement of the heel. The above-mentioned brassiere may be a type in which the back tape is manufactured separately on the left and right sides and the back side is connected with a hook, or the back tape is manufactured on the left and right sides, and the front cloth is separated between the left and right cups You may make it the form which connects a right and left front cloth with a hook.

The woven structure of the back tape is arbitrary, and may be any of plain weave, twill weave, satin weave and its changed structure. In addition, the ear tissue is arbitrary as long as there is no increase or decrease in the number of warps throughout the entire length of the fabric tape, and fraying does not occur, and is not limited to the folded ear formed by shuttle reciprocation. Arbitrary ears such as folding ears, binder ears, and electric heat cut ears can be appropriately selected. During weaving, the width of the fabric tape is gradually changed by the vertical movement of the heel, so that the ear warp is not bent by the tension of the weft and a smooth ear line is formed. In addition, the shape of the woven tape for one back tape is generally a quadrilateral in which the front cloth side end portion is the maximum width portion and the back side end portion is the minimum width portion, but is not limited thereto. As described above, the upper side and the lower side can be formed into a curved line.

And, a wide-width portion having a constant width can be formed continuously at the wide-side end portion of the back tape, and a narrow-width portion having a constant width can be continuously formed at the narrow-side end portion. In this case, the tape width is stable, It becomes easy to set large inclinations of the upper side and the lower side. The weft density of the fabric tape constituting the back tape is preferably set relatively dense on the wide side where the warp density is coarse, and relatively coarse on the narrow side where the warp density is dense. The appearance of the tape is leveled and the stability of the tape width is improved.

In the above-mentioned woven tape, the elastic warp mixed with the warp is exemplified by a filament yarn of spandex fiber, and in particular, a covering yarn in which the filament yarn of spandex fiber is covered with a synthetic fiber crimped yarn, for example, wooly nylon yarn. preferable. Further, the normal weft for normal warp and weft having no rubber-like elasticity may be any of natural fiber, regenerated fiber or synthetic fiber, but the raw multifilament yarn of synthetic fiber and its crimped yarn are mixed. The case is preferable in that the fabric can be thinned, the fashionability is improved, and the touch is soft, and the use of cotton fiber or regenerated fiber is preferable in that the sweat absorption is improved.

As described above, the brassiere according to the present invention is formed by forming a back tape with a stretchable fabric tape, and is formed into a desired shape while appropriately increasing or decreasing the weaving width during weaving. Therefore, it is easy to assemble the brassiere, and the thickness becomes uniform, and there is no thick part along the upper and lower sides as in the past. The upper side, the lower side, and the middle part of the stretchable elasticity should be set appropriately according to the arrangement of the elastic warp yarns. Can do. In particular, the invention according to claim 2 has good width stability even in a portion having a wide width and a coarse warp density, or a portion having a narrow width and a dense warp density. In the invention according to claim 3, the stability of the width on the wide side and the width on the narrow side is further improved, and the appearance is improved.
