DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a metal component for underwear .

[0002]

2. Description of the Related Art Conventionally, components for underwear, for example, a core material or a ring such as a brassiere cup holding wire, a bra shoulder strap adjusting ring, a bra band end hook, a corset spiral bone, and the like. Is generally made of metal.

[0003] Among such underwear metal components,
Particularly, those requiring toughness are made of iron, and those requiring omission of painting and plating are made of stainless steel.

By the way, underwear is sewn with a sewing machine.
At the time, do not forget to remove the folded needle and
It may occur, but such folded needles and town needles
Danger of being pierced by the user's body if left as a residual needle
There is. Such problems are widespread in general clothing,
When externally installing a jacket, coat, etc.
In many cases, minor injuries are sufficient even if
In the case of underwear, in order to directly touch the wearer's skin,
When the remaining needle pierces the body, a serious
There is a risk of developing into an accident .

In this regard , in the field of clothing,
In recent years, magnetic induction type or electromagnetic induction type needle detectors have been provided.Before shipping, let the clothes pass through the needle detector, and check in advance whether you have forgotten to remove metal pieces such as sewing needles and town needles. I have.

[0006] Such a meter reading is generally performed twice. That is, the first needle probe is used to detect whether or not the sewing needle remains after attaching relatively small accessories such as fasteners, front rings, snaps, etc. attached to the sewing machine in the sewing process. (For convenience, referred to as high-sensitivity meter reading). In the second meter reading, after attaching a relatively large accessory such as a metal button, it is checked whether the user has forgotten to remove the needle (for convenience, referred to as a low-sensitivity meter reading).

For example, according to a conveyor type needle detector provided by Sanko Electronics Research Laboratory Co., Ltd. (1677 Kusue, Takatsu-ku, Kawasaki-shi), the sensitivity level (detection ability).
Is provided with two types, A sensitivity for the high-sensitivity meter reading and B sensitivity for the low-sensitivity meter reading.

In order to detect the folding needle of the sewing machine, the A sensitivity has a detection capability equivalent to 1.2 mmφ in terms of iron ball. Therefore, in order to clear the A sensitivity, the fastener, the front ring, the snap, and the like attached to the clothing subjected to the search at the A sensitivity must be 1.1 mmφ or less in terms of an iron ball.

In order to detect a town needle, the B sensitivity is
It has a detection capability equivalent to 2.5 mmφ in iron ball conversion. Therefore, in order for a metal button or the like mounted on the clothing subjected to the search at the B sensitivity to clear the B sensitivity, the iron ball conversion is 2.4 m.
mφ or less.

[0010]

SUMMARY OF THE INVENTION As described above, the present invention
According to their findings, the need for meter reading is
It is especially high in underwear than general clothing,
If the needle is not applied to the underwear, there is a danger
It is .

However, underwear, such as a bra
In the case, a wire for shape retention is inserted around the cup,
Has a length adjustment ring, and a detachable hook at the end of the band
Is attached .

[0012] For this reason, the lower part including such a metal component is required.

Instead, an abnormal signal is generated. In other words,
Underwear that has issued an abnormal signal when passing through the meter,
Dangerous even though not all contain residual needles
Headaches of manufacturers returned and returned as products
Becomes In addition, such metal components may cause abnormal signals.
, An abnormal signal is frequently issued and the
Needle work is complicated .

[0013] In this regard, or to made conventional metal constructs all synthetic resin, if the light alloy such as aluminum, it is possible to prevent abnormal detection in the needle work, metal underwear The composition, like the wire for brassier shape retention mentioned above, its use, function,
From the viewpoint of appearance texture, etc., it is absolutely required to have the same physical properties as iron and stainless steel, the appearance due to the background, and furthermore, it is required to eliminate the need for painting and plating.All components are made of synthetic resin Or, it is not in line with the actual situation to use a light alloy.

[0014]

Means for Solving the Problems The present inventors wear underwear.
While the metal component of this product is still made of metal having the same rigidity and toughness as iron and stainless steel, small rings that were machined in the sewing process during the first meter reading with a high-sensitivity meter It has been found that the above problem can be solved if a relatively small metal component such as a hook or a hook is configured to be nonmagnetic with an iron ball equivalent of 1.1 mmφ or less that can reliably clear the A sensitivity of the needle detector. did. In addition, at the time of the second meter reading by the low-sensitivity meter meter, a relatively large metal component such as a D ring or a wire core can surely clear the B sensitivity of the meter meter at 2.4 mmφ or less. It has been found that the above-mentioned problem can be solved by configuring the device to be non-magnetic.

Therefore, based on such findings of the present inventors, it has been found that austenitic stainless steel produces preferable results when selecting a metal material for a metal component. Generally, austenitic stainless steel is
This is because it is considered to be non-magnetic.

However, relatively small components, such as small rings and hooks, and relatively large components, such as D rings and wire cores , were prototyped using austenitic stainless steel available on the market. When these were passed through the meter reader, it was found that the A sensitivity and the B sensitivity of the current meter reader could not be cleared.

That is, of the austenitic stainless steels available on the market, the weight is about 6 g by SUS304.
When a ring was prepared as a trial and tested, it was found that it was equivalent to 1.5 mmφ in terms of iron ball, and that the A sensitivity could not be cleared. In addition, similarly, the weight is about 13 g by SUS304.
When a D ring was trial manufactured and tested, it was found to be equivalent to 3.0 mmφ in terms of iron ball, and it was found that the B sensitivity could not be cleared at all. Similarly, the cup holder for the prototype bra
Even in the case of ears, iron ball equivalent 3.0 mmφ is far
It was confirmed that it exceeded .

This implies that austenitic stainless steel is generally considered to be non-magnetic, but it is presumed that, at a severe level of sensitivity, such as a needle detector, a reaction has an inevitable fine magnetism. . Alternatively, even if it is non-magnetic, it is theoretically known that it may be magnetic depending on its chemical composition and the rate of cold working ,
It is presumed that a metal that requires cold working, such as a metal component, has a part of austenite transformed into martensite and becomes magnetic, resulting in the above-described results.

The metal composition for underwear according to the present invention uses stainless steel because it has excellent rigidity and toughness, and does not require plating, and the like. It is formed by cold-working non-magnetized stainless steel and maintains non-magnetism even after cold-working.
It has a characteristic in that it has

When using austenitic stainless steel, it is preferable that the chemical component contains at least 0.1% or more of N in order to demagnetize the austenitic stainless steel.
Moreover, in order to improve the workability in addition to the non-magnetic properties, it is more preferable to contain Cu.

Therefore, the present invention contains N at 0.1% or more.
In particular, it is demagnetized and contains Cu.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1A shows a bra 1 as an example of underwear . On the periphery of the cup of bra 1
Wires 2 for shape retention are inserted, and the wires 2 are formed by bending a metal round wire into a predetermined arc shape by cold working , and have a strong elastic restoring force. .

Also, the shoulder strap of the brassiere 1 is shown in FIG.
A metal length adjusting ring 3 as shown in FIG. 1 (B) is provided, and a removable male fitting 4 and a female fitting 5 as shown in FIG. A hook 6 is provided.

The metal components exemplified as the wire 2, the adjusting ring 3, and the hook 6 have the same shape and dimensions as those conventionally known, and may or may not be subjected to heat treatment. As the metal material, a metal material satisfying toughness and non-magnetism has been selected.

In the illustrated embodiment, the metal component included in the brassiere 1 is composed of the wire 2, the adjusting ring 3, the hook 6, and the like. However, the adjusting ring 3 and the hook 6 which do not require particularly high rigidity and toughness are used. Can be made of a synthetic resin, and only the wire 2 may be a metal component. Therefore, in the case of the brassiere 1, the metal component of the present invention may be constituted by the wire 2, the adjusting ring 3, and the hook 6, or may be constituted by only the wire 2.

When selecting a metal material that satisfies rigidity, toughness, and non-magnetism for such a metal component of the brassiere, in the present invention , austenitic stainless steel is selected and cold worked. It is manufactured by. That is, the metal components such as the wire 2, the adjustment ring 3, and the hook 6 as shown in the figure are formed by cold working austenitic stainless steel round wire.

As described above, austenitic stainless steel is generally considered to be non-magnetic,
304, SUS305, SUS310, SUS316,
In addition, when a brassiere wire 2 is experimentally manufactured using commercially available ones, any wire can not clear the B sensitivity of the needle detector at all.
As described above, among the austenitic stainless steels, in particular, non-magnetized stainless steel is used to achieve the object of the present invention.

In particular, a metal component formed by cold working, such as the wire 2, the adjustment ring 3, and the hook 6, is an austenitic stainless steel and has a chemical composition containing at least N of 0.1%. Use the ones contained above.

According to the knowledge of the present inventors, austenitic stainless steel usually has an austenitic phase structure at normal temperature, but when cold worked, a part or most of austenite is transformed into martensite and becomes magnetic. Will take on. However, when N, which is considered to be an austenite-forming element, is included, the tendency to transform into martensite is weakened, and the magnetic properties of a metal composition composed of two wires, two control rings, and two hooks as shown in the illustrated embodiment are reduced. In order to demagnetize until the B sensitivity of the needle detector becomes lower than the B sensitivity (2.5 mmφ in terms of iron ball), good results were obtained by containing 0.1% or more of N.

Further, in order to facilitate the cold working of such a metal component, it is preferable to use austenitic stainless steel which is particularly non-magnetized as described above and contains Cu as a chemical component. It is good to make it. According to the findings of the present inventors, the inclusion of Cu facilitates deformation during cold working. Moreover, Cu
Is considered to form an austenite-forming element like N, and contributes to weakening the tendency to transform into martensite by cold working, and has an effect similar to two birds per stone.

Next, an embodiment considered as the best mode of the present invention will be introduced.

Example 1 A round wire of austenitic stainless steel having the following chemical components was cold-worked to produce a wire 2 having the shape shown in FIG. 1A and meeting the following specifications. . The chemical components in steel are as follows: C is 0.04%, Si is 0.40%,
Mn is 5.15%, P is 0.030%, and S is 0.000.
%, Ni is 5.55%, Cr is 18.21%, Cu is 2.47%, Nb is 0.09%, and N is 0.193%. This wire weighs about 6 g per wire.

The wire of Example 1 was subjected to a needle test function test and found to be equivalent to an iron ball equivalent of 0.6 mmφ. Therefore, the B sensitivity of the meter reader (manufactured by Sanko Electronics Research Laboratories) could be cleared without any problem by using two wires as one set.

By the way, at the time of the needle meter function test, the chemical components of C were 0.01 to 0.05% and Si was 1.
0% or less, Mn is 3.0 to 7.0%, and Ni is 5.0
To 6.0%, Cr is 17.0 to 19.0%, C
Several types of wires with u varied in the range of 1.0 to 4.0%, Nb in the range of 0.2% or less, and N in the range of 0.1 to 0.3% were prototyped, and each was subjected to a test. It was recognized that the equivalent of iron wire per wire was 0.7 mmφ or less.

As for the composition of the chemical components, the conventional SU
S304, SUS305, SUS310, SUS316
Etc. all make Mn 2.00% or less,
In the above embodiment, Mn is set to 3.0% or more,
Forms an austenite-forming element and contributes to weakening the tendency to transform into martensite by cold working.

(Example 2) A round wire of austenitic stainless steel having the following chemical components was cold-worked to form a wire 2 having a shape as shown in FIG. Made. The chemical components in steel are as follows: C is 0.07%, Si is 0.5
3%, Mn is 9.85%, P is 0.020%, and S is 0.8%.
000%, Ni 5.62%, Cr 18.08%, N
Is 0.298%. This wire weighs about 6 g per wire.

The wire of Example 2 was subjected to a needle test function test and found to be equivalent to 0.5 mmφ in terms of iron ball. Therefore, the B sensitivity of the meter reader (manufactured by Sanko Electronics Research Laboratories) could be cleared without any problem by using two wires as one set.

By the way, at the time of the needle meter function test, the chemical components of C were 0.07 to 0.10% and Si was 1.10%.
0% or less, Mn is 9.0 to 10.0%, and Ni is 5.
0 to 6.0%, Cr is 17.5 to 18.5%,
Several types of wires with N changed in the range of 0.25 to 0.35% were prototyped, and each of them was subjected to a test. Each of the two wires was recognized as having a set of 1.3 mmφ or less in terms of iron ball. .

Also in this example, compared with the conventional SUS series, Mn is contained at a high content of 9.0% or more.
It is recognized that Mn forms an austenite forming element and contributes to weakening the tendency to transform into martensite by cold working.

Example 3 An austenitic stainless steel thin round wire having a chemical composition within the same range as in Example 2 was cold-worked to form an adjustment ring 3 as shown in FIG. And FIG. 1 (C)
The hook 6 shown in FIG. Therefore, the adjustment ring 2
As a result of setting the two sets of pieces and hooks as a set and subjecting them to a needle detector function test, it was determined that the total was 0.4 mmφ or less in terms of iron balls.

As described in the above embodiment, according to the result of the needle meter function test, the two wires 2 are 1.3 mmφ in terms of iron balls.
The adjustment ring 3 and the hook 6 are 0.4 mmφ or less in terms of iron balls in the set state of the above number.

Therefore, by combining the two wires of the first or second embodiment with the set of the adjusting ring 3 and the number of hooks 6 of the third embodiment, a total of the meter reading made by Sanko Electronic Laboratory Co., Ltd. When passed through the tester, the B sensitivity (2.5 mmφ in terms of iron ball) of the company's meter was able to be cleared in 10 of the 10 tests.

The above-mentioned non-magnetized austenitic stainless steel has a gloss comparable to that of a conventional hard chromium-plated product, has high corrosion resistance, and has rigidity and toughness as a metal component of a bra. It has sufficient properties.

In the first embodiment, since Cu is contained, the cold working of the metal component is easy.
And 3 have a strong spring force.

On the other hand, one set of a folding needle at the tip of the sewing machine is added to the set of the two wires of the first or second embodiment and the number of the adjusting rings 3 and the hooks 6 of the third embodiment. When the whole was passed through a needle detector manufactured by Sanko Electronic Laboratory Co., Ltd., an abnormal signal was generated at the B sensitivity, and the presence of a folded needle was detected. When a test was performed by adding one of the staples, an abnormal signal at the B sensitivity was similarly generated.

Although the embodiment has been described above, it is needless to say that the present invention is not limited to the above embodiment. In particular, it is clear that the invention can be applied not only to the metal components of the brassiere described above but also to a wide variety of metal components of underwear . For example, the present invention can be widely applied to metal spiral bones sewn into a corset and other underwear metal components such as rings.
