Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a decorative composite twisted gold thread using fine gold wire of high purity for use in woven or knitted fabrics. More specifically, it is made by concentrically twisting fine gold wires and further concentrically twisting the concentrically twisted threads for the required number of threads.The appearance is a striped pattern with golden light and shade, which is necessary when weaving woven or knitted materials. The present invention relates to a decorative composite twisted gold thread characterized by significantly improved bendability and flexibility.

(Prior art) Woven and knitted fabrics in which gold and silver threads have been woven have been known for a long time.The method for making these gold and silver threads is to attach gold and silver leaf to ganpi gi and cut it into thin strips. After wrapping the yarn around the core yarn, pasting a pasty liquid mixed with whole silver powder onto the first-twisted single-twisted yarn, drying it and giving it a strong final twist, or after vacuum-depositing gold and silver onto the base sheet. It is known to have a protective layer coated with synthetic resin paint thereon, cut into long and thin pieces, and then wrapped around a core yarn.

In particular, with vacuum-deposited silver, a yellow protective layer is applied to make decorative gold thread, or thin (indium plating) is applied to prevent the silver from discoloring in the atmosphere, or silver is coated with a high-grade linear alkylimidazole. The corrosion resistance of silver has been improved by a method of chelating the surface of silver.

(Problems to be Solved by the Invention) As mentioned above, gold and silver threads are made by pasting gold and silver foil on a garland, or by vacuum-depositing gold and silver on a base sheet and cutting the material into thin strips. In the former case, it is expensive to produce gold and silver foil of uniform thickness, and a special technique is required to apply the gold and silver foil.

In the latter case, there is a large loss due to scattering of gold and silver during vacuum evaporation, resulting in poor yield.

Therefore, the above-mentioned gold and silver threads are considerably more expensive than decorative gold and silver threads obtained by vacuum-depositing aluminum on a base sheet, but they do not cause contamination of woven or knitted fabrics or damage due to use. In some cases, it is practically difficult to recover gold and silver as precious metals, so even luxurious woven and knitted fabrics have the disadvantage of having no asset value.

However, these gold and silver threads, which are wound around core threads in various colors at intervals, exhibit a geometric spiral color striped pattern, giving them a beautiful and decorative appearance. .

One of the challenges is whether such bright and dark colored striped patterns can be created using high-purity fine gold wire.

Therefore, a woven or knitted fabric was woven using soft pure gold wire with a diameter of 0.05 to 0.3 mmφ, but the breaking load, bendability, and flexibility of the gold wire did not match the weaving processing conditions, so it was not easy to weave. Problems such as wire breakage, bending, or significantly impeding workability during weaving occur, and the appearance of the resulting woven or knitted fabric is flat and lacks a three-dimensional effect, and although it exhibits an elegant golden color, it is simply a golden color. However, there is a lack of color stripes due to geometric shading.

The purpose of the present invention is to solve this problem by reducing the number of thin gold wires used to create a bulky composite twisted gold thread with a three-dimensional effect, and improving the appearance of the outer layer formed by twisting the wires. To provide a composite twisted gold thread for decoration which has a light and dark color striped pattern in which shadows in the valleys and bright golden yellow are alternately spiraled.

Another object of the present invention is to remove the pure gold thin wire used in the woven or knitted fabric from precious metals if the woven or knitted fabric becomes contaminated or damaged after the decorative composite twisted gold thread according to the present invention is woven into a woven or knitted fabric. It also provides the potential for gold to be recovered and to enhance the potential role of gold as an asset.

(Means for Solving the Problems) The configuration for solving the object of the present invention has a diameter of 0.05 to
0.2mmφ high-purity fine gold wires with the same wire diameter are twisted concentrically,
The required number of concentric twists is further concentric, and the twisting pitch is set to 3 of the diameter of a circle passing through the center of the outer layer wire (hereinafter referred to as the layer core diameter).
This is a composite twisted gold thread for decoration, which is made soft by twisting the thread to a ratio of 0 times or less and annealing it.

Next, when pure gold soft gold fine wire is woven into a woven or knitted fabric, there is a risk of breakage due to the cross-sectional area of 7.85 x 10-
It has been confirmed that the diameter is 3 mm2 or less (corresponding to a diameter of 0.1 mmφ) and the breaking load is 107 gf or less.

Therefore, the minimum configuration of the present invention is 0.05 mm in diameter.
φ, composite twisted gold thread with 6 twists.

If the structure is less than this, the breaking load will be low and there is a risk of wire breakage during weaving of the woven or knitted material.

The reason for using the maximum configuration of the present invention, that is, a composite twisted gold thread with a diameter of 0.2 mmφ and 49 twists, is because if the configuration exceeds this configuration, the outer diameter will become large, which will impede workability when weaving woven or knitted materials. It is.

The twist pinch in the structure is preferably 30 times or less the layer core diameter.

This is because if the value exceeds this value, the twists will unravel due to the bending process during the weaving process, creating spaces where the strands are intertwined, resulting in an unsightly appearance. The preferred twisting pitch range is 10 to 25 times the layer core diameter.

The chemical composition of the fine gold wire used in the present invention is 18K (10
0% x 1B/24) or more. This is because if the value is less than 18, the recovery price of gold will be low when recovering gold as a precious metal from woven or knitted fabrics, and the asset effect will be lost.

The preferred chemical composition of the gold wire is 24.

Next, the required number of fine gold wires of 0.05 to 0.211 mφ with the same wire diameter are bundled together and twisted together in the same direction, and then 3 to 7 threads are concentrically twisted to form a composite twisted gold thread. be able to.

Figure 5 shows a composite twisted gold thread consisting of 21 pieces, with one of the fine gold wires as the center line (8), and a fine gold wire of the same diameter (8) above it.
If 1) is made into a 7-strand configuration (9) in which 6 concentric twists are twisted, and the concentric twist (9) is further concentrically twisted into a compound twist (10), there is a small gap between the lines of the 7-strand concentric twist. Cleavage (4)
A large valley (5) is formed between the lines of the outer layer and the line of the outer layer, and together they create a shadow.

The exterior has a colored striped pattern similar to that shown in Figure 4, and is luxurious and bulky.

Figure 6 is a reference diagram of a concentrically twisted gold thread with 19 strands using fine gold wire, with one of the fine gold wires as the center line, and on top of it, six fine gold wires of the same wire diameter are concentrically twisted to the left. After twisting, 12 fine gold wires were twisted concentrically to the right.

In such a case, small valleys (4) are formed between the lines of the outer layer, causing small shadows, but large valley shadows as shown in FIGS. 1 to 5 do not occur.

For example, the composite twisted gold thread shown in FIGS.
In contrast to the concentrically twisted gold thread shown in the figure, the composite twisted gold thread according to the present invention has a concentric appearance when twisted with a number of threads less than or similar to the number of thin gold wires used for the concentrically twisted thread. From the twisted gold thread itself,
Large valleys are formed between the lines of the outer layer, resulting in larger shading, which exhibits a spiral pattern of brighter and darker color stripes alternating with golden yellow, and makes it more luxurious and bulky for decoration.
