Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for producing decorative compressed gold thread using fine gold wire of high purity for use in woven fabrics.

More specifically, it is made by concentrically twisting fine gold wires of high purity.
The wire is passed through a wire drawing die with a diameter smaller than the outer diameter, and then compressed into a circular shape, with recesses formed between the wires in the outer layer, and the recesses are filled with a colored synthetic resin or paint to give the outer layer a gold-colored striped pattern. The present invention relates to a method for producing decorative compressed gold thread, which is characterized by applying it in a spiral shape.

(Prior art) Conventional methods for making gold and silver threads include pasting gold and silver foil on Mashibigi, cutting it into thin strips and wrapping it around a core yarn, and mixing gold and silver powder into single-twisted yarn that has been pre-twisted. A paste-like liquid is pasted, dried and highly twisted, or gold and silver is vacuum-deposited onto a base sheet, and a protective layer is applied with synthetic resin paint on top of the base sheet, which is then cut into thin strips. A method is known in which the fiber is wound around the core thread.

In particular, for silver threads with vacuum-deposited silver, the protective layer is made yellow to make decorative gold threads, thin indium plating is applied to prevent the silver from discoloring in the atmosphere, and high-grade linear alkylimidazole is used to coat the silver surface. It has been used to improve the corrosion resistance of silver by chelating it.

(Problems to be Solved by the Invention) As mentioned above, should gold and silver leaf be pasted on the ganpi gi?
Alternatively, gold and silver threads made by vacuum-depositing gold and silver on a substrate and cutting them into thin strips may have an excellent decorative appearance, but in the former case, manufacturing gold and silver foil of uniform thickness is expensive, and Special techniques are required to apply silver foil.

In the latter case, the loss due to scattering of gold and silver due to vacuum deposition is large, 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 V& knitted fabrics or damage due to use. In some cases, recovery of precious metals in the form of gold and silver becomes difficult in practice, so even luxurious woven and knitted fabrics have the disadvantage of having no asset value.

However, these gold and silver threads, which are made of core threads of various colors and wound with gaps, exhibit a geometric spiral color striped pattern and have a beautiful and decorative appearance. ing.

One of the issues is whether such colored striped patterns can be formed using thin gold wires made of pure gold.

Next, we attempted to weave a woven or knitted fabric using soft pure gold wire with a diameter of 0.05 to 0.3 mm, but the breaking load, bendability, and flexibility of the fine gold wire were insufficient for the weaving process. Because the wires do not meet these conditions, they easily break, bend, or otherwise significantly impede workability during weaving, and the overall appearance of the resulting woven or knitted material has a unique, elegant golden color. However, it is simply a golden color and does not exhibit color stripes due to geometric shading.

For example, if a colored striped pattern made of intermittent ring marks can be applied to the surface of a thin gold wire using paint or the like, the appearance will become more decorative. However, since the gold wire used in the present invention has an extremely small diameter, it is extremely difficult to paint and color it using the ring mark method.

Even if it is made, the part with the ring mark may become knotted and bend during weaving or knitting, or the colored part of the ring mark may be subjected to friction, abrasion, bending, trauma, etc. during subsequent use. Colored paint marks will peel off, fall off and lose their decorative value.

Therefore, as shown in Figure 3, one of the thin gold wires is connected to the center line (
As for 2), about the gold thread (1) consisting of seven pieces on which thin gold wires of the same wire diameter are concentrically twisted, colored synthetic resin or As a result of trying to fill the paint (6) to form a colored striped pattern with the gold, as shown in Figure 4, the front surface of the outer periphery of the gold thread was completely coated with the colored synthetic resin or the paint (6), and the outer layer Since the gold wires are not exposed on the surface, the concentrically twisted gold thread (1) has no decorative value.

The purpose of the present invention is to solve this problem by compressing gold thread made of pure gold kumquat wire concentrically twisted into a circular shape, providing recesses between the lines in the outer layer, and filling the recesses with colored synthetic resin. Another object of the present invention is to provide a method for manufacturing decorative compressed gold thread, which is filled with a paint and has a bright and dark colored striped pattern of spiral-shaped sushi with a golden yellow glow and resin filling the recesses.

Another object of the present invention is to remove the pure gold wire used in the woven or knitted fabric when the woven or knitted fabric becomes contaminated or damaged after the decorative compressed gold thread according to the present invention is woven into the woven or knitted fabric. It also provides the ability to recover precious metals and increase the asset value of woven and knitted products.

(Means for Solving the Problems) Means for solving the objects of the present invention have a diameter of 0.05 mm.
Any one of the high-purity fine gold wires with a diameter of ~0.2 mm
The center line is a book or 3 to 5 strands twisted together,
On top of that, fine gold wires of the same wire diameter are concentrically twisted, and the twist pitch is the diameter of a circle passing through the center of the outermost wire (hereinafter referred to as the layer core diameter).
The total number of strands in the twisted configuration is 7.
~61 twisted gold threads.

The compression ratio of the various twisted gold threads thus constructed is 3%.
As described above, after passing through a wire drawing die with a diameter smaller than the finished outer diameter of the twisted gold thread and compressing it into a circular shape, the compressed gold thread is tempered for a short time in a temperature range of 500 ± 10 ° C to obtain a soft compressed gold thread, A coloring thermoplastic resin or thermosetting resin is filled into the gap between the recesses formed between the outer layer wires of the compressed gold thread, so that the appearance of the compressed gold thread has a colored striped pattern of golden yellow and colored synthetic resin. It is characterized by being formed in a spiral shape.

Next, the reason why the configuration of the twisted gold thread before compression is set to the minimum, that is, the center line diameter is 0.05 mmφ and the number of twists is 7, is that if the configuration is less than this, the breaking load of mechanical properties will be low, and the weaving of woven and knitted materials will be This is because there is a risk of wire breakage during processing.

In addition, the maximum configuration, that is, the center line diameter of 0.2 mmφ and the number of twists of 61, is because if the configuration exceeds this configuration, the finished outer diameter of the gold thread will become thick (which will hinder workability during weaving of woven or knitted materials). This is because there is a risk of causing

The preferred configuration range of the twisted gold thread is a center line diameter of 0.07.
The diameter is ~0.15 mm, and the number of twists is 7 to 37.

The twisting pinch of the twisted gold thread is preferably 50 times or less the diameter of the layer core.

This is because if the value exceeds that value, the twist will easily unravel due to the bending stress received during weaving of the woven or knitted material.

A preferred twisting pitch is in the range of 910 to 25 times the layer core diameter.

Next, the preferred compression ratio is in the range of 4-15%.

When the compression rate of the twisted gold thread is less than 3%, the arcuate portion of the outer layer that is compressed and polished by the wire drawing die becomes smaller, and the band-like streaks of the colored synthetic resin filled in the recesses between the outer layer wires become larger, resulting in a poor appearance. This is because it will lose its decorative value.

If the compression rate is increased, the twisted gold thread will take on a solid shape, which is not preferable.

Furthermore, the chemical composition of the fine gold wire used in the present invention is 18K (
100%X 18/24) or more, preferably 24
It is.

If it is less than 18, when the compressed gold thread woven into the woven or knitted fabric is recovered as a precious metal, its recovery value will be low and the asset effect will be lost.

The Vikasoto softening temperature (7206 in J13) of the thermoplastic resin or thermosetting resin used is preferably 60°C or higher. The reason for this is to take into account the environmental temperature to which the decorative compressed gold thread is subjected during use or storage.

(Function) This will be explained for the seven-strand gold thread structure shown in FIGS. 1 and 2.

When concentrically twisted gold threads (1) are compressed into a circular shape using a wire drawing die, the center line (2) is not deformed, but the entire outer layer "ffA (3)" is greatly deformed, and the green wire A recess (5) is formed between the large arc portion (4) polished by the die and the line of the outer layer.

When the gap between the recesses is filled with a colored thermoplastic resin or thermosetting resin (6), the colored synthetic resin filled in the arc part (4) and the recesses will move in the length direction of the compressed gold thread (7). On the other hand, in the case of Menja, the sushi is in the form of bright golden bands, while in the latter, colored synthetic resin forms the sushi in the form of bands, creating an alternating spiral pattern of colored stripes, with an appearance similar to that of elegant decorative gold threads. Become.

Above, we have explained an example of compressed gold thread with seven threads.
The appearance of each compressed gold thread having a multilayer twisted structure also exhibits a color striped pattern of golden yellow and colored resin, as described above.
