Description

  The present invention relates to a metal wire used for an annular accessory represented by a necklace, a bracelet, and a rosary (bead).

  Traditionally, through holes have been drilled in jewelry such as Akoya pearls, Black butterfly pearls, White butterfly pearls, Freshwater pearls, Mabe pearls, Crystals, Onyx, and jewelry decoration materials such as cubic zirconia, crystal glass, quartz, and shells. Annular jewelry and ornaments represented by necklaces, bracelets, and rosary beads are manufactured by passing yarns made of fibers through these through holes.

  Yarns made of fibers are subject to aging and wear, and there is a possibility that problems due to yarn breakage may occur. To avoid this, the user needs to replace the yarn regularly. As a solution to the problem of yarn made of this fiber, a metal wire material such as stainless steel wire was employed as a substitute, such as Japanese Utility Model Application Publication No. 07-005409, Japanese Patent Application Laid-Open No. 2001-037615, Japanese Patent Application Laid-Open No. 2001-128835, and the like. Things have been reported. However, in the use of annular accessories and ornaments represented by necklaces, bracelets, and rosary beads, rust is likely to be generated from metal wires, and trouble is likely to occur. In addition, since there is a risk that rust is transferred and soiled by the wearer's clothing, generally stainless steel that does not easily rust is often used.

  In the case of using a metal wire such as a stainless steel wire, there is a problem of a habit of a trace left by bending due to compositional deformation unlike a fiber yarn. In order to solve this problem, there has been proposed one using a shape memory alloy as disclosed in JP-A-2005-224413.

  When metal wire such as stainless steel wire, shape memory alloy, super elastic shape memory alloy, etc. is used, the metal wire is scraped by friction with the above-mentioned gem or jewelry decoration material, and waste is generated. The problem is that the area around the through-holes on the surface of the jewelry or jewelry decoration material attached in black is dirty.

The reporter infers that the black stain is due to the above-mentioned causes, but detailed clarification is thought to require academic research. In any case, the black stain is a factor that significantly lowers the product value of accessories and ornaments that place an emphasis on the appearance of the item. It must be a problem.

  The problem to be solved is to reduce the wear of the metal wire due to friction with the jewelry or jewelry decoration material that occurs when using metal wire such as stainless wire, shape memory alloy, super elastic shape memory alloy, etc. It is to prevent the problem that the periphery of the through hole in the surface layer of the jewelry or jewelry decoration material is stained black.

  In the present invention, a metal wire surface layer such as a stainless steel wire, a shape memory alloy, a superelastic shape memory alloy, or the like is sufficiently hardened by a method having excellent adhesion after sufficiently performing electrolytic polishing or chemical polishing in a pretreatment. By precious metal plating, the main feature is to reduce the wear of the metal wire due to friction with jewelry or jewelry decoration material.

  As a result, the wear of the metal wire due to friction with the jewelry or jewelry decoration material is reduced, and the periphery of the through hole in the surface layer of the jewelry or jewelry decoration material is black and is not soiled.

  As the hard noble metal plating that can be used in the present invention, rhodium sulfate plating, rhodium phosphate plating, composite plating of rhodium sulfate and rhodium phosphate, rhodium-based rhodium alloy plating, ruthenium plating, ruthenium plating, ruthenium-based ruthenium There are alloy plating, gold plating, gold-based gold alloy plating, palladium plating, palladium-based palladium alloy plating, platinum plating, platinum-based platinum alloy plating. The presently optimal hard noble metal plating in the present invention is rhodium phosphate plating.

 Typical examples of the metal wire that can be used in the present invention include stainless steel, shape memory alloy, superelastic shape memory alloy, and the like. Examples thereof include a wire tube, a spiral densely wound twisted wire combining a plurality of metal wires, a spirally closely wound hollow twisted wire combining a plurality of metal wires, and a metal coil wire.

  Metal wires such as stainless steel wire, shape memory alloy, super elastic shape memory alloy of the present invention have hard noble metal plating with excellent adhesion on the surface layer, so Akoya pearl, black butterfly pearl, white butterfly pearl, Resistant to abrasion due to friction with jewelry such as freshwater pearls, mabe pearls, crystal, onyx, or jewelry decoration materials such as cubic zirconia, crystal glass, quartz, shells, etc. It became possible to do. As a result, even when annular accessories such as necklaces, bracelets, and rosary beads were manufactured, the problem of black and dirty surroundings of the through-holes on the surface of the gem or jewelry decoration material was solved.

A metal wire which is a spiral densely wound hollow stranded wire in which a plurality of superelastic shape memory alloy wires are combined is prepared, and this is subjected to hard rhodium phosphate plating with excellent adhesion. Necklaces and bracelets are then passed through through holes in jewelry such as Akoya pearls, Black butterfly pearls, White butterfly pearls, Freshwater pearls, Mabe pearls, Crystals, Onyx, or jewelry decoration materials such as cubic zirconia, crystal glass, quartz, and shells. And we produce ring accessories and ornaments represented by rosary.

  12 pieces of a 0.1 mm diameter wire rod made of super elastic shape memory alloy were cut to the required length, and after this was sufficiently electropolished by pretreatment, a rhodium phosphate plating apparatus prepared as appropriate Was used to apply hard rhodium phosphate plating with excellent adhesion without unevenness on the entire surface. Separately, twelve samples without plating were also prepared.

  A stranded wire was produced by bundling 12 pieces of 0.1 mm diameter wire rod made of super elastic shape memory alloy plated with rhodium phosphate so as to be within an outer diameter of 1 mm. Separately, a stranded wire was similarly manufactured so that 12 super 0.1 mm diameter wire rods made of super elastic shape memory alloy not plated with rhodium phosphate were bundled to fit within an outer diameter of 1 mm.

  This rhodium phosphate-plated super elastic shape memory alloy stranded wire is passed through ako or pearl with the required number of through-holes instead of the thread, and separately prepared fittings are attached to both ends. I made a necklace. Separately, a super-elastic shape memory alloy stranded wire that is not plated with rhodium phosphate is passed instead of a thread through an ako or pearl with the required number of through holes, and a connector prepared separately is attached to both ends. Akoya pearl necklaces were made in the same way. Both of them have the effect of super elastic shape memory alloy in appearance and feeling of wearing, and it became a ring-shaped Akoya pearl necklace with moderate tension that cannot be obtained with ordinary fiber yarn.

  Using the Akako and pearl necklaces with different specifications depending on the presence or absence of plating of these two superelastic shape memory alloy stranded wires, a mounting test such as bending and detachment assuming actual use was performed and compared.

  In the Akoya pearl necklace using a super elastic shape memory alloy stranded wire not plated with rhodium phosphate, which is not subjected to the present invention, the peripheries of the pearls that appear between the pearls become black when repeated several hundred times. It gets dirty. This dirt moved to the wearer's clothes and had a high risk of getting dirty, and it became an undesirable condition for jewelry.

  In the Akoya pearl necklace using a rhodium phosphate plated super elastic shape memory alloy twisted wire that has been subjected to the present invention, the peripheries of each pearl that can be seen between the pearls appear to be darkly stained even after being repeated several hundred times. Nothing happened, and he continued to maintain the desired state of clothing.

  Prepare 24 strands of 0.1mm diameter wire rod made of super elastic shape memory alloy and cut them to the required length, and bundle 2 strands to produce 2 stranded wires to fit within 1mm outer diameter did.

  One of the manufactured superelastic shape memory alloy stranded wires is sufficiently electropolished by pretreatment, and then, using an appropriately prepared rhodium phosphate plating apparatus, hard rhodium phosphate plating with excellent adhesion without unevenness on the entire surface Was given. One of the remaining superelastic shape memory alloy stranded wires was used for the next step as it was.

  This rhodium phosphate-plated super elastic shape memory alloy stranded wire is passed through ako or pearl with the required number of through-holes instead of the thread, and separately prepared fittings are attached to both ends. I made a necklace. Separately, a super-elastic shape memory alloy stranded wire that is not plated with rhodium phosphate is passed instead of a thread through an ako or pearl with the required number of through holes, and a connector prepared separately is attached to both ends. Akoya pearl necklaces were made in the same way. Both of them have the effect of super elastic shape memory alloy in appearance and feeling of wearing, and it became a ring-shaped Akoya pearl necklace with moderate tension that cannot be obtained with ordinary fiber yarn.

  Using the Akako and pearl necklaces with different specifications depending on the presence or absence of plating of these two superelastic shape memory alloy stranded wires, a mounting test such as bending and detachment assuming actual use was performed and compared.

  In the Akoya pearl necklace using a super elastic shape memory alloy stranded wire not plated with rhodium phosphate, which is not subjected to the present invention, the peripheries of the pearls that appear between the pearls become black when repeated several hundred times. It gets dirty. This dirt moved to the wearer's clothes and had a high risk of getting dirty, and it became an undesirable condition for jewelry.

  In the Akoya pearl necklace using a rhodium phosphate plated super elastic shape memory alloy twisted wire that has been subjected to the present invention, the peripheries of each pearl that can be seen between the pearls appear to be darkly stained even after being repeated several hundred times. Nothing happened, and he continued to maintain the desired state of clothing.

  Using a 0.2 mm diameter wire made of a super elastic shape memory alloy, a wire wound in a coil so as to be within 1 mm in outer diameter was manufactured. From there, it was cut into the required length, and two superelastic shape memory alloy coil wires were produced.

  One of the manufactured superelastic shape memory alloy coil wires is sufficiently electropolished by pretreatment, and then, using an appropriately prepared rhodium phosphate plating apparatus, hard rhodium phosphate plating with excellent adhesion without unevenness on the entire surface Was given. One of the remaining superelastic shape memory alloy coil wires was used in the next step as it was.

  Pass the rhodium phosphate-plated super elastic shape memory alloy coil wire instead of the thread through the necessary number of through holes, pearls and pearls, and attach separate connectors at both ends. I made a necklace. Separately, a super-elastic shape memory alloy coil wire that is not plated with rhodium phosphate is passed through an ako or pearl with the necessary number of through holes instead of yarn, and a separately prepared connector is attached to both ends. Akoya pearl necklaces were made in the same way. Both of them have the appearance and wearing feeling of a superelastic shape memory alloy, have moderate tension that cannot be obtained with ordinary fiber yarns, and have the elasticity of a circular ring or pearl necklace with the effect of coil wire.

  Using these two Akako and pearl necklaces with different specifications depending on the presence or absence of plating of the superelastic shape memory alloy coil wires, a mounting test such as bending and detachment assuming actual use was performed and compared.

  In the Akoya pearl necklace using the coil wire made of super elastic shape memory alloy not plated with rhodium phosphate, which is not applied to the present invention, the peripheries of the pearls that are visible between the pearls become black when they are repeated several hundred times. It gets dirty. This dirt moved to the wearer's clothes and had a high risk of getting dirty, and it became an undesirable condition for jewelry.

  In the Akoya pearl necklace using the rhodium phosphate plated super elastic shape memory alloy coil wire according to the present invention, even if it is repeated hundreds of times, the peripheries of each pearl that can be seen between the pearls are stained black. Nothing happened, and he continued to maintain the desired state of clothing.

In general, accessories such as yarn made of fiber, warmth, flag, tapestry, emblem, etc., jewelry such as Akoya pearl, black butterfly pearl, white butterfly pearl, freshwater pearl, mabe pearl, crystal, onyx, etc. or cubic It can be used not only in combination with jewelry decoration materials such as zirconia, crystal glass, quartz, and shells, but also in applications that use combinations of colored glass, ceramics, ores, and metal wires.
