Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to decorative 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, giving it a golden-yellow colored striped pattern, which significantly increases the breaking load, bendability, and flexibility required when weaving woven or knitted materials. This invention relates to a decorative gold thread characterized by improved properties.

(Prior Art) Woven and knitted fabrics in which gold and silver threads are woven into fabrics, or in which bows and bows are woven into fabrics have been known for a long time. Methods for making these gold and silver threads include pasting gold and silver foil on Mashikigi, cutting it into long strips and wrapping it around a core thread, or using a paste-like liquid mixed with gold and silver powder on single-twisted threads that have been pre-twisted. After gluing, drying, and applying strong ply-twisting, or vacuum-depositing gold and silver onto the base sheet, a protective layer is applied with synthetic resin paint on top of the base sheet, which is then cut into thin strips and wound around a core thread. What is attached is known.

In particular, with vacuum-deposited silver, a yellow protective layer is applied to make decorative gold thread, a thin indium plating is applied to prevent the silver from discoloring in the atmosphere, and a high-grade linear alkylimidazole is used to coat the surface of the silver. The corrosion resistance of silver has been improved by a method of converting it into a clear 1 or higher.

(Problems to be Solved by the Invention) As mentioned above, the appearance of gold and silver threads obtained by pasting gold and silver foil on the tanepi-gi, or by vacuum-depositing gold and silver on a base sheet and cutting them into thin strips, is However, 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, the loss due to scattering of gold and silver during vacuum evaporation is large, resulting in poor yield.

Therefore, while 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, they are less susceptible to contamination or damage due to use. If this occurs, it becomes virtually difficult to recover the precious metals as gold and silver, 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 with gaps, exhibit a geometric spiral color striped pattern and have a beautiful and decorative appearance. There is.

One issue is whether something similar to this kind of colored stripe pattern can be formed using high-purity gold wire.

Therefore, an attempt was made to weave a woven or knitted fabric using soft pure gold thin wire with a diameter of 0.05 to 0.3 mm, but the breaking load, bendability, and flexibility of the thin gold wire depended on the weaving processing conditions. Because of the incompatibility, 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 feel, giving it an elegant appearance. Although it has a golden color, it is simply a golden color and lacks geometric striped patterns.

The purpose of the present invention is to solve this problem by concentrically twisting high-purity fine gold wires to form valleys between the wires in the outer layer, giving the outer layer a shiny golden spiral appearance. To provide a decorative gold thread which exhibits alternating bright and dark colored striped patterns using the valleys between the lines as shading, and which has significantly improved mechanical properties required for weaving woven or knitted materials compared to a thin gold wire alone. It is. Another object of the present invention is that after weaving the decorative gold thread according to the present invention into a woven or knitted fabric,
When woven or knitted fabrics become contaminated or damaged, the high-purity fine gold wire used in woven or knitted fabrics is recovered as a precious metal.
It also serves to increase the potential asset value of gold.

(Means for Solving the Problems) The configuration that solves the object of the present invention is to concentrically twist high-purity thin gold wires, and specifically, in a gold thread in which fine gold wires are twisted concentrically. , the diameter of the gold wire is 0.0
5 to 0.2 mmφ, and the center of the thin gold wire with the same wire diameter is located at the vertex of an equilateral triangle, square, or pentagon, and the diameter of the circle passing through the center of the outer layer wire (hereinafter referred to as 3 to 50 times or less of the layer core diameter)
Twist 5 strands together or have a diameter of 0.05 to 0.2
One or two to five of the high-purity fine gold wires of mmφ are twisted together as the center line, and the fine gold wires of the same wire diameter are placed concentrically on top of the center line, and the twisting pinches are used to adjust the layer core diameter. 5
Twist as 0 times or less, and the total number of strands in the twist configuration is 7 to 6.
It is characterized by a single twisted gold thread.

The minimum of the above configuration range, that is, wire diameter 0.06 open φ,
The reason why the number of twists is 3 or the center wire diameter is 0.05 mmφ and the number of twists is 7 is that if the structure is less than this, the breaking load as a mechanical property will be low, so there is a risk of wire breakage during weaving of woven or knitted materials. This is because there is.

In addition, the maximum configuration range, that is, the center line diameter is 0.2 mm.
φ and the number of twists is 61 because if the structure exceeds this, the outer diameter will become large and the workability during weaving of the woven or knitted material will deteriorate significantly.

Next, it is preferable that the twisting pinch in the above structure be 50 times or less the diameter of the layer core.

This is because if the value exceeds that value, the bending process applied during the weaving process of the woven or knitted material will cause the strands to loosen, creating spaces between the charcoal and the joints, which will deteriorate the appearance.

A preferred twisting pitch is 1n, which 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 18/24) or more. 19 if less than 18
This is because when fine gold wire is recovered from knitted fabrics as a precious metal, the recovery price of gold becomes low and the asset effect is lost.

The preferred chemical composition of the gold wire is 24.

Note that the decorative gold thread according to the present invention is preferably an annealed soft material.

Next, thin gold wires of 0.05 to 0.2 mmφ with the same wire diameter are bundled together and twisted in the same direction, or twisted in groups in an appropriate cross-sectional area, or concentrically twisted in the required manner. Composite twisted yarns with several concentric twists have good flexibility and can be used as decorative gold threads in woven and knitted fabrics in the same manner as in the present invention.

(for production) The operation will be explained with reference to FIGS. 1 to 3.

In the 1st I21, one of the thin gold wires was set as the center line (1), and a thin gold wire (1") of the same wire diameter was concentrically twisted on top of it.
When using the gold thread (2) of this configuration, the valleys (3) between the lines of the outer layer become shadows, and its appearance exhibits a spiral geometric bright and dark colored striped pattern of bright golden yellow and shadows alternating. In Fig. 2, if we assume that the three gold threads (5) are concentrically twisted to the right so that the centers of the thin gold wires (4) of the same wire diameter are located at the vertices of an equilateral triangle, the valleys between the outer layer wires ( 3) becomes a shadow, and its appearance exhibits a color striped pattern of light and dark golden yellow. In Figure 3, there are three concentrically twisted gold threads (
5) is the center line, and above it is a fine gold wire (4゛) of the same wire diameter.
When the gold thread (6) is made up of 13 concentrically twisted left-handed twists, the valleys (3) form shadows between the lines of the outer layer, giving the appearance a color striped pattern of shadows and golden yellow.

(Example) Example 1 A thin gold wire is placed on a 24 piece with a diameter of 0.14 mmφ as the center line, and 6 thin gold wires of the same wire diameter are placed concentrically on it, and the twisting pinch is set to 18 times the diameter of the layer core, and the right twist is made. The gold thread consists of seven strands.

The gold thread was softened using a continuous softening device adjusted to a temperature of 500±10° C. to obtain a decorative gold thread.

The appearance of the obtained ornamental gold thread was a bright golden color and the valleys between the outer layer lines were shaded, creating an alternating spiral pattern of beautiful geometric bright and dark color stripes.

Example 2 24. with a diameter of 0.1 mmφ. Using the K gold thin wire as the center line,
Six fine gold wires of the same wire diameter are placed concentrically on top of this, and charcoal and lipinochi are made 50 times the layer core diameter to form a gold thread consisting of seven wires. The gold thread was annealed in the same manner as in Example 1 to obtain a soft decorative gold thread.

Example 3 A three-strand gold thread with a diameter of 0.14 mm ψ was made so that the center of the gold wire was located at the vertex of an equilateral triangle and the twisting pinch was 20 times the layer core diameter. The gold thread was annealed in the same manner as in Example 1 to obtain a soft decorative gold thread.

Table 1 shows the results of a free bend test corresponding to breaking load, bendability, and flexibility using a thin gold wire 24 having approximately the same cross-sectional area as the above-mentioned example as a comparative example.

A free bend test involves placing a sample between 80mm chucks, bringing both chucks close to each other by 10mm, and then
Return to original position. Count this as one piece and measure the number of times until it breaks.

(The following is a blank space, continued on the next page.) As can be seen from the results, the number of free vents of the decorative gold thread according to the present invention is significantly lower than that of the comparative example.
It can be easily woven into m'tFA material.

(Effect of the invention) The decorative gold thread according to the present invention has a significantly lower number of free bends than the thin gold wire having the same cross-sectional area, so it is easy to weave, and the woven or knitted fabric is similar to the actual one. It has sufficient resistance to severe bending stress during use.

The appearance of decorative gold thread is a bright golden color in the length direction, and the valleys between the outer layer lines create shadows that alternate to create an elegant spiral pattern of bright and dark colored stripes, making it more woven than fine gold wire alone. When woven into knitted fabrics, it produces a more luxurious and decorative effect.

Furthermore, the decorative gold thread according to the present invention can recover gold from woven or knitted fabrics when they are contaminated or damaged, and can enhance the role of the woven or knitted fabric as an asset, contributing to demand. The degree of this is enormous.
