Abstract

PROBLEM TO BE SOLVED: To obtain a bag weave tape for wire loop sewn on the lower side of brassiere, capable of facilitating the inserting operation of a wire and the sewing operation of a wire tape and preventing from breaking of the weave tape due to the protruding of the end part of the wire therethrough. SOLUTION: Highly stretchable winding yarn is arranged in warp of a bag weave tape. The winding yarn 2 is arranged in high density on the inner side of anti-sewing face of a hollow hole 5 through which a wire 3 is inserted. Preferably, sewing face of the bag weave tape is formed as a plain fabric 10 and the anti-sewing face is formed as longitudinal double weave 12 of an inner plain fabric 10 and an outside twilled fabric 11. The stretching ratio of the weaving tape is preferably 1.1 to 1.3. Although the resultant bag weave tape 1 itself is linear, the tape is bent along a curvature of the wire 3 when the bent wire 3 is inserted and the tape is free from occurrence of crease which becomes an obstacle in sewing operation. Woven structure having large through resistance is formed on a part of the side which attaches to the skin in the hollow hole 5.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire loop which is sewn to the lower side of a bra to improve shape retention, and a woven tape which is a thin sheath-like woven fabric surrounding the wire.

[0002]

2. Description of the Related Art A woven tape used for a wire loop is a flat tape woven with wooly nylon or polyester yarn, and a hollow hole for inserting a wire is formed in a center portion of the tape. The inner part is a plain weave and the outer part is a twill weave. The reason why the inside is a plain weave structure is to obtain a dense structure through which the end of the wire does not penetrate, and the reason why the outside is made to be a twill weave is to give a soft touch to the surface that contacts the skin.

A wire of a wire loop is a wire having a flat cross section in which the outer surface of a metal wire is protected with a synthetic resin, and is bent into an asymmetrical shallow U-shape along the lower side of the breast, and both ends thereof are rounded by a resin coating. Is given. This wire is inserted into the hollow hole of the above-mentioned woven tape, and both ends thereof are sewn so that the wire does not move. Then, the wire is sewn to the brassiere along both sides of the wire.

[0004] Since the woven fabric is woven by weaving wefts between warps aligned in parallel, the obtained woven tape is straight. On the other hand, since the wire inserted into the wire is bent in a shallow U-shape, the woven tape after the wire is inserted has wrinkles in a portion inside the wire in the bending direction. The work of sewing the wire loop to the brassiere is performed manually, but wrinkles generated on the woven tape of the wire loop make this sewing work difficult, and it is necessary to perform the sewing work while holding down the wrinkles. , Reducing work efficiency.

[0005] To address this problem, longitudinally curved woven tapes for wire loops have been provided. By arranging the yarns having different degrees of crimp on the warp yarns, the warp yarns are contracted asymmetrically in the heating step performed after weaving, and the woven tape is bent in the longitudinal direction.

The above-mentioned double weaving of plain weaving and twill weaving in this kind of woven tape is obtained by the operation of shedding warps. However, a twill weave structure is not required on the sewing surface side. In the above-mentioned sachet tape curved in the longitudinal direction, a sachet tape having a plain weave only surface on the mating side, and a plain weave and twill weave double weave structure on the anti-sew side only is provided. I have. If the weaving structure is a plain weaving and twill weaving double weaving structure, the center part of the tape width will be slightly swelled up, but if it is a plain weaving only structure, it will be a flat shape, so the above mating surface The sack weaving tape having only plain weave makes it easier to sew onto the brassier after the wire is inserted.

[0007]

As described above, the conventional woven tape for a wire loop that has been woven in a straight line has a wrinkle inside in the bending direction when a wire is inserted, as described above. It becomes an obstacle. On the other hand, the woven tape for a wire loop having a shape curved in the longitudinal direction can suppress the occurrence of wrinkles when the wire is inserted, but for that purpose, the bending direction of the tape and the bending direction of the wire are set to the same direction, Must be inserted. In other words, the woven cloth tape bent in the longitudinal direction facilitates the sewing operation, but has a problem that the operation of inserting the wire through the tape becomes complicated. Further, while the wire has an asymmetric shape with different curvatures in the longitudinal direction, the tape has a constant curvature in the longitudinal direction, so that it is inevitable that some wrinkles are partially generated.

Further, the conventional woven tape for a wire loop has a problem that the tissue may become loose during repeated washing or the like, and the end of the wire may break through the woven tape and protrude.

Therefore, the present invention can perform the operation of inserting a wire through a woven tape and the operation of sewing the obtained wire loop to a brassiere both easily and efficiently, and the end of the wire can be woven with the woven tape. An object of the present invention is to provide a woven tape that does not have a possibility of breaking through and projecting, and a wire loop using the same.

[0010]

The wrapping tape for a wire loop according to the present invention has a winding yarn having high elasticity in a warp. The winding thread 2 is arranged at a high density inside the anti-sewing surface of the hollow hole 5 through which the wire 3 is inserted. Preferably, the sewn surface of the woven tape is a plain weave 10, and the anti-sewn surface is an inner plain weave 10 and an outer twill weave 11, a double weave 12. Suitably, the stretch ratio of the woven tape is 1.1 to 1.3.

The wire loop of the present invention is obtained by inserting a wire 3 bent in a deformed U-shape along the lower side of the breast into the woven tape having the above-described configuration.

[0012]

The woven tape 1 of the present invention is linear in itself, but when the bent wire 3 is inserted into the hollow hole 5,
Since the outer portion in the bending direction extends, the woven tape 1 bends in accordance with the curvature of the wire 3 and flexibly copes with a change in the curvature of the wire in the longitudinal direction. Does not occur. Further, since the diameter of the winding thread 2 is larger than that of another warp thread 9 such as a wooly nylon or a polyester thread, by closely arranging the winding thread 2, the central portion of the tape width on the anti-sewing surface side, that is, the hollow hole 5 through which the wire passes. Since a woven tissue having a large penetration resistance is formed in the portion on the side that contacts the skin, it is possible to avoid a situation in which the tip of the wire breaks through the woven tape 1 and protrudes.

[0013]

1 to 4 show an embodiment of the present invention. FIG. 1 schematically shows a cross section of a woven tape 1 mainly with a warp. The woven tape 1 is provided at a central portion of a flat tape having a sewn surface 7 and a non-sewn surface 8 on a brassiere fabric 6. It is a bag fabric in which a hollow hole 5 for inserting the wire 3 is formed.

The anti-sewing surface 8 of the woven tape 1 has a plain weave 10 on the inside and a twill weave 11 on the outside.
(Double woven fabric with two types of warp and one type of weft)
And the sewing surface 7 is a plain weave 10.

The width of the weaving tape 1 is about 12 mm, the width of the hollow hole 5 is about 5 mm, and the total number of warp yarns is about 120, of which about 20 are winding yarns 2 having high elasticity and others are wooly-processed yarns. 9. The weft is generally a wooly processed yarn.

As the high stretch yarn, natural rubber or urethane-based spandex is used.
%, But it is set to 10% to 30% in the woven tape 1 by adjusting the thickness, density, and weave structure of the winding yarn and the weft.

The twill weave 11 is preferably an eight-slant sentence (FIG. 3 shows an organization chart of a 6/2 slanted sentence, which is an example of an eight-slant sentence), and the plain weave 10 has an organization chart shown in FIG. 2 and 3, the horizontal direction of the grid indicates the weft, the vertical direction indicates the warp, and the hatched portion indicates a state in which the warp is floating above the weft. The twill weave 11 is a state in which a large amount of warp floats on the surface, gives a soft touch to the skin, and does not easily wrinkle.

A winding yarn 2 of a high expansion / contraction yarn thicker than the wooly-processed yarn 9 is arranged on the inner plain weave 10 portion of the anti-sewing surface 8 of the hollow hole 5 at a higher density than other portions, and the strength of the plain fabric in this portion is increased. Increase. Coupled with the elasticity of 10 to 30%, loosening of the woven tissue due to repetition of washing or the like is unlikely to occur, and there is a danger that the end of the wire 3 inserted into the hollow hole 5 will break through the woven tape 1 and protrude. Absent. Further, when the wire 3 is inserted through the hollow hole 5, the sewing surface 7 is flat,
The anti-sewing surface 8 tends to swell slightly, which is convenient for sewing the brassiere 6.

When the bent wire 3 is inserted through the hollow hole 5 of the woven tape 1, the wrapped tape 1 is bent in accordance with the curvature of the wire 3 by extending the outer side in the bending direction of the woven tape 1. Since it flexibly responds to the change in the curvature in the direction, wrinkles that hinder the sewing operation to the brassiere 6 do not occur. Experimentally, the expansion and contraction rate of the woven tape is 10 to 3
The effect at 0% was remarkable.

Since the woven tape 1 is bent in any direction, the direction of insertion of the wire 3 is not required, and the efficiency of the insertion operation is improved.

Next, a method of weaving the woven tape 1 will be briefly described. However, there is no difference from the conventional method except for the use of warp threads. Using a narrow needle loom having upper and lower needles, two wefts are inserted into the upper and lower sheds by two needles. The plain weave 10 and twill weave 11 of the anti-sewing surface 8
A single weft (upper side) is simultaneously woven to make a double weave 12. The sewing surface 7 weaves a plain fabric with another weft (lower side). Both side portions of the hollow hole 5 are sewn surfaces 7 and 2
The two woven fabrics are closely bonded to each other to form a bonded double woven fabric 13.
The binding double weave 13 opens the warps of the sewing surface 7 and the anti-sewing surface 8 to the shed on the opposite side appropriately, and weaves the weft yarns.

The winding yarn 2 having high elasticity according to the present invention
Since the warp yarn 9 has a significantly different expansion and contraction rate from the other warp yarns 9 (wooly processed yarn), it is wound around another warp beam and supplied to the loom.

[0023]

According to the present invention, a winding yarn having high elasticity is arranged in a warp of a wrapping tape for a wire loop, and the winding yarn is densely formed on an inner plain weave portion of an anti-sewing surface of a hollow hole through which a wire is inserted. By arranging and setting the expansion and contraction rate of the woven tape to 1.1 to 1.3, wrinkles due to bending of the woven tape at the time of wire insertion do not occur, and the cloth strength on the inside of the anti-sewing surface of the hollow hole is increased,
The risk that the wire end face breaks through and protrudes through the woven tape can be prevented. In addition, since there is no direction of wire insertion of the woven tape, the wire insertion work efficiency is improved, and the productivity, quality and safety of the wire loop are remarkably improved. On the other hand, since the wire loop has no wrinkles and the sewn surface is flat, the productivity of the brassier sewn seam is also improved, and the appearance is very good.
