Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to women's clothing having a function of correcting and shaping the body, in particular, comfort when worn, which is used in underwear for correction such as underwear and clothing having a breast cup, and corsets. The present invention relates to a clothing core material for the purpose of improving the quality.

[0002]

2. Description of the Related Art Conventionally, a bra, a long line bra, a body suit, a teddy bra, a camisole,
Women's clothing with breast cups such as underwear or breastwear such as leotards, swimwear, evening dresses, and bustier type outerwear with breast cups such as bra slip, bustier, three-in-one, and correction underwear for women with body shape correction and shaping functions, For example, corsets, girdle, west nippers and the like are widely used as clothing for women.

[0003] In the case of underwear or clothing having a breast cup,
In order to adjust the shape of the breast and make the silhouette as beautiful as possible, those having a cup wire bone in a substantially semicircular shape on the substantially lower half periphery of the cup edge of the breast are widely used, and the cup wire bone is widely used. By using the rigidity of the cup, the cup is deformed to keep the shape of the breast beautiful.

[0004] Also, in the case of a core material for clothing to be embedded in a correction underwear such as a corset, girdle, and a waist nipper, a function similar to that of a cup wire bone is required. Things.

[0005] The core material for clothing, which is a generic name for these, is made of steel, a shape memory alloy, mainly a polyacetal resin such as DURACON (registered trademark), a polyester resin,
Those made of polycarbonate resin are common and widely used.

[0006] Among them, a metal core material such as steel or shape memory alloy has a correction effect, but has excessive rigidity and lacks flexibility, so that the wearer feels a foreign body feeling or cramped feeling. There were many things. In addition, since the metal core material is used, the weight of the entire garment becomes heavy, and the user often feels tired during wearing. Therefore, the comfort during wearing cannot be satisfied.

On the other hand, cores made of polyacetal resin, polyester resin,
A plastic core such as a polycarbonate resin has been proposed. However, compared to metal cores,
Although it is lightweight, there is a problem that it is not possible to simultaneously satisfy the moderate rigidity essentially required of the core material for clothing and higher resistance to washing.

[0008]

SUMMARY OF THE INVENTION Therefore, the present invention has a moderate rigidity and a comfortable wearing, and a toughness that provides resistance to washing and the like, which could not be solved by the conventional core material. It is an object to provide a new core material for clothing.

[0009]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that a core material for clothing using magnesium as a shaft material exhibits excellent performance. Reached. That is, the present invention relates to "a core material for clothing embedded in women's clothing having a body shape correction / shaping function using a magnesium alloy as a shaft material" and "a body shape correction / shaping function using a magnesium alloy as a shaft material." And a cup wire bone embedded along the lower edge of the cup portion of the bra.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below. Since pure magnesium is very soft and is not suitable for the structural material such as the core material for clothing of the present invention, the magnesium used for the core material for clothing according to the present invention refers to a magnesium alloy. A magnesium alloy is magnesium to which another metal is added for modification, and the metal to be added can be exemplified by aluminum, manganese, silver, zinc, silicon, thorium, zirconium, mesh metal, yttrium, rare earth, and the like. It is not limited to. The metal to be added and the amount of the metal added are not particularly limited.
Aluminum 8-10%, zinc 5
~ 0.5%.

Aluminum is used to improve castability, and has the function of increasing strength by solid solution hardening, precipitation hardening, and strengthening of crystallized material dispersion. However, the addition amount is 10
%, The strength is increased, but the elongation is reduced, the material becomes brittle, and it tends to be unfavorable as a core material for clothing. If the amount is less than 8%, the effect of increasing the strength tends not to be expected.

On the other hand, zinc is used for the purpose of improving corrosion resistance. However, if the addition amount is more than 5%, strength and elongation are reduced, so that it becomes a brittle material, which is not preferable as a core material for clothing. It is in. Furthermore, the addition amount is 0.5%
If the amount is smaller than the above range, the effect tends not to be expected even though it is used for improving corrosion resistance.

The material used for the core material for clothing according to the present invention is not necessarily essential, but in order to impart desired physical properties, other known materials are added as long as the performance is not impaired. May be. As other materials that can be added,
Aluminum nitride, calcium, zirconium, carbon,
Hexachloroethane and rare earths can be exemplified, but there is no particular limitation.

In the method of molding a core material for clothing according to the present invention, the magnesium alloy in a chip form is charged from a hopper into an injection molding machine provided with a mold in the shape of a core material for clothing, and heated and melted and kneaded to a semi-molten state. The method is not limited to this, but may be a die casting method, an extrusion method, or the like, and there is no particular limitation.

[0015] The magnesium core material obtained as described above may be used as it is as a core material for clothing after performing processing such as deburring of the periphery, sanding, and blasting. You may process by a method and thing.
For example, the surface may be coated with a plastic material having flexibility in consideration of contact with the skin and in order to reduce wear and abrasion of the fibers of the garment material because it is a metal wire. Further, for the same reason, it is also possible to exemplify that the end of the wire bone is formed in a chip shape.

In the case of coating with the above-mentioned plastic substance, there are no particular restrictions on the type of plastic substance, coating method, and coating conditions, and any known method may be used.
Further, a known method may be used for forming a plastic material in a chip shape at the end of the wire bone, and there is no particular limitation.

As a use of the molded body of the magnesium alloy molded as described above, for example, it can be suitably used for a core material for clothing, particularly a cup wire bone, and overcomes the drawbacks of the conventional core material for clothing.

Hereinafter, the present invention will be described with reference to examples.
