探知することが行われている。2. Description of the Related Art In sewing products such as clothing, a part of a needle (mainly a needle point) may be broken at the time of sewing work and may remain in a fiber tissue as it is. Due to various factors, a minute metal piece similar to a broken needle may be mixed or adhered during a sewing operation or the like. Broken needles and metal pieces (hereinafter referred to as "broken needles") mixed and adhered to such sewn products are very small and extremely difficult to detect with the naked eye. The product may be shipped. However, it is extremely dangerous to use a sewn product in which such broken needles and the like remain, and this is particularly a problem with clothing worn directly. For this reason, recently, since many broken needles and the like remaining on sewn products are made of magnetic metal such as iron, a needle detector having a magnetic metal detecting function is used.
Detecting whether a broken needle or the like remains in a sewn product before shipment is performed.

Various metal accessories such as snaps, hooks, metal fasteners (work teeth) are attached by means of sewing, bonding, etc. When such metal accessories are made of magnetic metal, they are attached to these. Also, the needle detector reacts, that is, malfunctions, and the broken needle or the like cannot be detected properly. Therefore,
As a constituent material of such a metal accessory, it is preferable to use a non-magnetic metal that does not react to the needle detector. further,
Many of the metal accessories that come with sewing products are metal buttons,
Since it is manufactured by deep drawing such as a snap or a hook, it is preferable to use a metal excellent in deep drawing workability as a constituent material.

不能である。However, such brass is a non-magnetic metal which does not react to a needle detector which is a kind of magnetic metal detector.
Depending on the arrangement or the like, the needle detector may react and malfunction even though there is no broken needle or the like. For this reason, reduce the sensitivity of the meter and the speed of detection by the meter to the extent that the detector does not react to the metal accessory made of brass, or arrange the metal accessory made of brass so that the meter does not react to it. It has been attempted to keep
The solution for avoiding malfunction of the meter has been extremely insufficient. That is, the detection of minute broken needles and the like becomes extremely uncertain only by lowering the sensitivity, and the efficiency of detecting broken needles and the like is greatly reduced when the sensitivity and the detection speed are lowered, resulting in a problem in cost. Further, the arrangement of the metal buttons, snaps, and the like are often inevitably determined based on the function of the sewn product, and generally cannot be freely changed. Therefore, it is actually very difficult to keep the arrangement of the metal accessories and the like so as not to cause a malfunction of the needle detector, and it is not feasible for many sewing products.

て検針器が誤作動することが判明した。The present inventor has conducted various experiments and studies in order to determine the cause of the reaction of a metal accessory made of brass, which is a non-magnetic metal, to a needle detector having a magnetic metal detecting function. As a result, brass is a non-magnetic metal but has extremely high conductivity, so when a sewing product with brass metal accessories is applied to a needle detector, depending on the arrangement of the metal accessories, etc. It was found that an eddy magnetic field was generated around the sensor, which caused the meter detector to malfunction.

重量％含有し、且つ残部が銅及び不可避同伴不純物から

る。かかる理由から、Ｍｎの添加量は０．５〜６．０重
量％とした．Mn is added to form a solid solution in brass to lower the conductivity and improve drawability. However, if the addition is less than 0.5% by weight, the conductivity cannot be sufficiently reduced, and unless the sensitivity of the meter is reduced, the malfunction may occur. vice versa,
If the addition amount exceeds 6.0% by weight, the drawability becomes poor, and it becomes impossible to satisfactorily deep-draw buttons and the like. For this reason, the added amount of Mn is set to 0.5 to 6.0% by weight.

ら、ニッケルの添加量は０．１〜４．０重量％とした。[0010] Ni itself has magnetism, but it is well dissolved in brass, improves drawability, and lowers conductivity. The effect of the decrease in conductivity due to the addition of Ni is as follows.
n is not so large as compared with n,
Stabilizes the conductivity of a Zn-Mn-based alloy;
Anisotropy generated during deep drawing of an n-Mn alloy is reduced, and good deep drawing can be performed. However, 0
If it is less than 1% by weight, the effects of conductivity, stabilization of electrical conductivity and anisotropy are small. Conversely, even if it exceeds 4.0% by weight,
No improvement in the above effects commensurate with the added amount was observed, and Ni
Is expensive, so there is also an economic problem. For this reason, the addition amount of nickel is set to 0.1 to 4.0% by weight.

から、亜鉛の添加量は、１０〜３５重量％とした。Zn is added for improving the deep drawability and decreasing the conductivity. However, if the content is less than 10% by weight, such an effect is small. On the contrary, if the content exceeds 35% by weight, the deep drawability deteriorates rather. For this reason, the amount of zinc added is 10 to 35% by weight.

However, the copper-based alloy No. 1 to No. No. 6 has both deep drawability and suitability for a needle detector, and was confirmed to be extremely suitable as a constituent material of a metal accessory such as a metal button attached to a sewn product.

よく確実に行なうことができる。As can be easily understood from the above description, the copper-based alloy of the present invention has a deep drawability equal to or higher than that of brass, and has a higher conductivity than brass. Is extremely low, so that it is extremely suitable as a component of a metal accessory attached to a sewn product both in the production of metal accessories and in detection by a needle detector such as a broken needle. That is, when the copper-based alloy of the present invention is used, metal accessories such as metal buttons and snaps can be favorably manufactured by deep drawing, and remain on sewing products without causing malfunction of the needle detector. It is possible to efficiently and reliably detect broken needles and the like.
