Description

  The present invention relates to a textile product, and specifically relates to a yarn, a string obtained by twisting a plurality of yarns, a rope obtained by knitting a plurality of strings, a fabric obtained by weaving a plurality of yarns, and the like. This textile product is used to manufacture jewelry such as bracelets, necklaces, ornaments and decorative coatings in the field of jewelry, and to manufacture particularly expensive products such as lingerie and swimwear in the clothing field. Especially suitable.

  The invention also relates to a method for producing such a textile product.

  As is known, in the field of goldsmith products, the purity of precious metals (gold, platinum, rhodium, etc.) is measured in carats. Carat represents the wt% of precious metal present in the final product. For goldsmith products, values in the range of 8-24 carats are generally used as commercial carat weights. This corresponds to the precious metal being in the range of 33 to 99.9 wt%.

  Conventional precious metals for jewelry are generally alloys composed of a precious metal (for example, gold) and a base metal (for example, copper, nickel, zinc, etc.), and the base metal generally makes the precious metal stronger. There is a role. The carat weight of the noble metal is determined by the wt% of the noble metal in the alloy.

  As is known, precious metals can be drawn into yarns. However, although yarns obtained from precious metals are easy to bend, they cannot be processed by machines common in the field of textiles (such as looms).

  Further, it is necessary to consider that the yarn obtained from the noble metal has a large specific gravity. Therefore, this yarn is not suitable for manufacturing a large volume goldsmith product due to its weight and cost.

  The object of the present invention is to solve these drawbacks of the prior art, to provide a goldwork product which is very pliable, has many applications and is particularly suitable for processing on machines common in the textile field. .

  Another object of the present invention is to provide a carat-heavy textile product commonly used in the field of goldsmith products.

  Another object of the present invention is to provide a goldwork product with a very large volume / mass ratio so that a large and very light noble metal product is obtained.

  These objects are achieved by the present invention having the features indicated in the product according to the appended independent claim 1 and the features indicated in the method according to independent claims 13 and 14.

  Preferred embodiments of the invention emerge from the dependent claims.

  The textile product of the present invention, particularly used in the field of goldsmith products, contains at least one expensive yarn, including the base yarn coated with the desired carat heavy noble metal.

  The base yarn is composed of a core made of a plastic material or synthetic fiber and coated with a metal material. The noble metal coating is obtained by electroplating the surface of the coating against the base yarn.

  The advantages of the textile product according to the invention are clear. In fact, textile products such as yarns and fabrics can be obtained by processing a base yarn having a synthetic fiber core with a machine common in the fiber field. Next, the semi-finished fabric product thus obtained is immersed in an electrolytic cell to attach a noble metal coating to the base yarn coating.

  By controlling this electrolysis process, the desired wt% noble metal, ie the desired carat weight, is obtained. In this way, a textile product is obtained which is particularly suitable for use in the field of goldsmith products, for example in the production of fabrics covering necklaces, bracelets, articles.

  Other features of the present invention will become more apparent through the following detailed description with reference to the embodiments illustrated in the accompanying drawings. The embodiments are merely examples, and the present invention is not limited to these embodiments.

  With reference to the drawings, a textile product, in particular for the goldsmith product and the garment field, and its manufacturing method will be described.

  FIG. 1 shows a base yarn, which is denoted by reference numeral 1 in its entirety. The base yarn 1 has a substantially cylindrical core 2 made of plastic material or synthetic fiber. It would be preferable to use nylon or polyamide as the plastic material. Other plastic materials such as PVC and silicone can also be used.

  The core 2 can be manufactured by extrusion, for example. Its diameter can be varied in the range of 20 microns to 2 mm to be suitable for processing in the textile field.

  The core 2 is covered with a coating 3 made of a metal material (for example, silver). The coating 3 is a few microns thick and is deposited on the surface of the core 2 by electroplating.

  A thread 1 serving as a base comprising a nylon core 2 and a silver coating 3 obtained by an electrolytic cell is known. The yarn is coated with silver to make it conductive. This yarn can then be used in the field of conductive products to conduct electricity.

  After conducting various experiments, the applicant has surprisingly found that such a base yarn 1 is suitable for coating precious metals by electrolytic processes in the textile field (for example yarns, ropes, fabrics). Etc.) was found to be particularly suitable for obtaining. In fact, the positive ions of the noble metal dissolved in the electrolytic cell move onto the silver coating 3 because the silver coating 3 of the base yarn 1 forms the anode of the electrolytic cell.

  A first embodiment of the present invention will be described below with reference to FIGS.

  As shown in FIG. 2, the base yarn 1 is wound around a spool 20. The base yarn 1 is unwound from a plurality of spools 20 and passes through a string manufacturing machine 21. The string manufacturing machine 21 twists the base yarn 1 to obtain a base 4 in which a plurality of base yarns 1 are twisted together. A sufficient number of spools 20 wound with a base yarn are used depending on the desired diameter of the string 4. The string 4 is wound around the bobbin 22.

  The string 4 is unwound from a plurality of bobbins or tubes 22 and passes through the rope manufacturing machine 23. Since the rope manufacturing machine 23 twists the string 4, the rope 5 is obtained as an output, and the rope 5 is wound around the bobbin 24. A sufficient number of string bobbins 22 are used depending on the desired diameter of the rope 5. Therefore, the rope 5 includes a plurality of strings 4, and each string 4 includes a plurality of yarns 1 serving as a base.

  Referring to FIG. 3, it is shown that the steel 5 obtained by the above process is immersed in an electrolytic cell included in the electrolytic cell 30 to perform a plating process.

  The electrolytic cell contains positive ions 31 of noble metal (for example, gold) dissolved in the solution. In particular, gold is selected as a specific example, but platinum, rhodium, silver or the like can be used as another noble metal instead of gold.

  More specifically, the rope 5 is wound around the side surface of the cylindrical cage 32 composed of a plurality of conductive rods 33. Since the cylindrical cage 32 is supported by a hook, it can rotate around its own axis.

  As can be seen from this figure, the cathode C of the electrolytic cell 30 is a cylindrical cage 32, and the anode A of the electrolysis cell is an electrolytic solution. By applying a sufficient potential difference V between the anode A and the cathode C, a current flows through the rod 33 of the cylindrical cage 32, so that the gold positive ions 31 dissolved in the solution move toward the rope 5. Accordingly, gold positive ions 31 are deposited on the surface of the silver coating 3 of the base yarn 1 that is a constituent of the rope 5. During this process, the cylindrical cage 32 is rotated in either direction so that a gold layer is uniformly deposited on the surface of the coating 3 for the base yarn.

  When the electrolysis process is finished, a woven product (indicated generally by reference numeral 50) is obtained, as shown in FIG. The textile product 50 is in the form of a rope containing a predetermined amount of gold. Each string 4 of the leash includes a plurality of expensive threads 7. As shown in FIG. 5, each expensive yarn 7 is composed of a base yarn 1 coated with a gold layer 6. The gold layer 6 is deposited on the outer surface of the silver coating 3 of the base yarn 1.

  By controlling the electrolysis process, the amount of gold contained in the textile product 50 of the present invention can be adjusted. In this way, the textile product 50 can be in a variety of commercial carat weights ranging from 8 to 24 carats.

  The textile product 50 according to the first embodiment is particularly suitable for use in obtaining jewelry (bracelet, necklace, ring, etc.) from a single rope or a plurality of twisted ropes 50 in the field of goldsmith products. Yes.

  It is possible not only for the surface of the finished product but also for the surface of the semi-finished product to have a gold coating 6 on the outer surface of the coating 3 for the base yarn 1 using an electrolytic cell. . In the latter case, a semi-finished product having a gold coating obtained using an electrolytic cell is processed with a loom to obtain a finished product. In fact, in any case, the core 2 made of plastic fibers ensures the bending properties necessary for processing on the loom.

  In addition, the jewelry obtained using the textile product 50 is much larger in volume than the jewelry obtained using a metal alloy having the same carat weight and mass. In fact, the volume / mass ratio of the tow 50 according to the present invention is about 10 times the volume / mass ratio of a tow made of a noble metal alloy having the same carat weight. Therefore, when the textile product 50 of the present invention is used, it is possible to obtain a light accessory with a large volume.

  A second embodiment of the present invention will be described with reference to FIGS. According to the second embodiment, as shown in FIG. 6, since the base yarn 1 can be arranged as warp and weft in the loom 9, a fabric product in the form of a fabric is obtained.

  The fabric 10 is then dipped in a gold electrolytic cell to the desired carat weight. In fact, also in this case, the gold ions in the electrolytic solution move to the outer surface of the coating 3 of the yarn 1 which is the base of the fabric structure.

  It can be seen that the gold coated fabric 10 is particularly suitable for use in the field of gold ware. For example, it is particularly suitable for use as a decorative coating for pens, lighters, trays, candlesticks, etc., as well as a decorative coating for general ornaments in general in the field of goldsmith products. The fabric 10 can also be used in the clothing field. For example, it can be used for the manufacture of particularly expensive clothes by designers and the manufacture of lingerie, swimwear, and the like.

  FIG. 7 shows an outline of a right-angled loom that can obtain a square fabric as an example. Note that the base yarn 1 can also be processed by other types of looms, such as ribbon making machines, knitting machines, Raschel looms, looms for non-wired fabrics.

  In this description, the base yarn 1 was processed by a loom, and the resulting woven product was immersed in an electrolyzer for gold plating. However, in another embodiment of the present invention, the base yarn 1 can be directly immersed in an electrolytic cell to obtain an expensive yarn 7 gold-plated to the desired carat weight. This expensive yarn 7 can then be used on a loom suitable for the desired product.

  Those skilled in the art will be able to make numerous variations and modifications to the details of the invention without departing from the scope of the appended claims.
