Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to the structure of gold and silver threads for textiles, particularly gold and silver threads having a pongee-like texture.

(Prior art) Conventionally, gold threads, silver threads, and other threads with metallic luster used in binding fabrics used for Japanese clothing obi fabrics, bags, etc. have been produced by using silk threads, synthetic resin threads, cotton threads, etc. as core threads. Flat foil thread with a metallic luster such as gold or silver is wrapped tightly around the core thread, so that the core thread itself is not visible from the outside, or the flat foil thread itself is used.

These gold and silver threads themselves have a beautiful appearance and are prized for decorative textiles. However, the surface shape of the yarn is simple, and the direction of strong reflection is easy to identify, resulting in the fabric woven from this having a dull, lack of elegance.

In addition, in order to dye these gold and silver threads, the flat foil thread itself, which has a metallic luster, must be colored.
The range of colors that can be dyed has also been limited.

(Purpose of the invention) This invention has a soft metallic luster, and the core yarn is dyed to express that color on the gold and silver thread.The synergistic effect with the metallic luster creates a decorative effect that has not been seen before. The aim is to obtain expensive gold and silver threads.

(Structure of the invention) This invention will be explained in detail below with reference to the drawings.

In the illustrated embodiment, the core yarn 1 is made of pongee yarn, acetic acid yarn, chemical fiber, or other yarn that is made by spinning and twisting waste cocoon or floss cotton, and is intentionally made so that thick and thin portions are irregularly formed. It is spun and dyed in any appropriate color, such as blue, red, or green, using standard techniques.

2 is a flat foil yarn with a metallic luster; for example, a metal such as aluminum, gold, silver, copper, etc. is vacuum-deposited on a polyethylene terephthalate film to obtain a film with a metallic luster, and this is slit into narrow widths using a sliver or the like. Obtained by shredding. If necessary, the aluminum vapor deposited layer may be colored as desired or a protective layer may be provided.

As shown in the figure, the gold and silver thread of this invention is made by inserting the above-mentioned flat foil thread onto the up-raised core thread 1, and then inserting the core thread 1 between them.
It is wound in a spiral pattern so that it is roughly exposed.

In addition, although the above-mentioned core thread has been described as being dyed before winding the flat foil thread, it goes without saying that it may be dyed after winding.

(Effect of the invention) Since the gold and silver thread of this invention has the above structure, the metallic luster of the flat foil thread and the color and texture of the core thread exposed between the flat foil threads are mixed to create a synergistic effect. It has a soft metallic luster with color and color.
Furthermore, the metallic luster and intensity of the colors change depending on the viewing angle, creating an iridescent effect.

The thickness of the core yarn is not uniform, and the flat foil yarn wound on it has a different inclination with respect to the center axis of the yarn depending on the part, and the direction in which strong luster is exhibited differs depending on the part. Therefore, parts exhibiting metallic luster are distributed on the yarn over a wide angular range, increasing the aesthetic appearance and softening the reflected light.

When a fabric is woven using this gold and silver thread, ridges appear irregularly on the fabric, and even if it is a plain weave, it has a pongee style texture and depending on the viewing angle, the ridges have a concealing effect that creates a beady appearance. The effect is further enhanced.

The average thickness of yarns whose thicknesses are intentionally made uneven is relatively thick, so when a weaving pattern is created using yarns of different thicknesses, the above effects are synergized, A fabric with a texture never seen before can be obtained.

The amount of flat foil yarn with high specific gravity used is small, and lightweight gold and silver yarn can be obtained.

By changing the thickness of the flat foil thread to be wrapped, the ratio of the area showing gold and silver luster to the area showing the core thread changes, making it possible to vary the texture over a wide range with the same structure.

It has the following remarkable effects.

Claims (1)

[Scope of utility model registration request] A flat foil thread 2 with a metallic luster is threaded roughly through the core thread 1, which is intentionally spun to have an uneven thickness and dyed in an appropriate color, to the extent that the core thread 1 is exposed from between. Gold and silver thread for textiles, characterized by being wrapped in a shape.
