Abstract

PURPOSE:To obtain the subject inexpensive gold and silver thread useful for woven or knitted fabrics, etc., remarkably producing metallic luster without causing elongation due to tension by forming gold and silver flat foil thread using Japanese paper as a core material into the shape of a braid. CONSTITUTION:A round type special gold and silver thread (B), having pseudo- inlaid hand and formed by laminating metallized films 3 with a vacuum deposition layer 2 as the inside to both surfaces of Japanese paper 1 and plaiting >=4 and an even number of the resultant flat foil threads (A) into the shape of a braid.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to special gold and silver threads used for various textiles, knittings, embroideries, etc.

(Prior art) It has been well known that threads with gold and silver luster are used for textiles, knitting, or sewing, and by using such metallic threads, the finished product itself can be luxurious and have added value. This is what we are trying to expect.

Such gold and silver threads are usually made into a filament by using two gold and silver threads and twisting them on the right or left side, or by winding a gold and silver flat foil thread in a spiral around the desired core thread. However, all of them are manufactured based on the concept of twisting, and therefore, a process to prevent untwisting is indispensable, resulting in high costs due to extra processing steps. There were defects such as peeling phenomenon in the foil part due to cent processing, which reduced the product value after weaving.

Furthermore, when using spirally wound gold and silver thread, the wound thread tends to be biased in one direction during weaving, making it impossible to produce a perfect product.

In addition, although such gold and silver threads have gold and silver luster, the color development is not remarkable (because the threads themselves have no complexity, the glittering properties as gold and silver threads are weakened especially after weaving). However, it had a defect in that the expected gold and silver luster pattern, design, etc. were not completely expressed.

(Problems to be Solved) In view of such defects, the special gold and silver thread for woven and knitted fabrics according to the present invention is made by braiding flat foil threads that have gold and silver luster on both sides, and then combining them with gold and silver. By using silver thread, it is possible to eliminate the defects of the conventional gold and silver threads, and it does not cause untwisting or peeling of the foil part, and is for woven or knitted fabrics that corrects the deviation of the gold and silver thread in one direction. The purpose is to provide special gold and silver thread.

Another object of the present invention is to provide a special gold and silver thread for woven or knitted fabrics that does not elongate due to the tension applied during weaving, yet has a pseudo-stitched texture and has an intense metallic luster.

(Means for Solving the Problems) In order to achieve the above-mentioned objects, the special gold and silver thread for woven and knitted fabrics according to the present invention has a vapor-deposited layer on both sides of the Japanese paper. It is characterized by special gold and silver thread for woven and knitted fabrics, which is made by laminating metal-deposited films and braiding flat foil threads in an even number of four or more to form a special round gold and silver thread with a pseudo-stitched texture. .

Next, an example of the implementation of the special gold and silver thread for woven or knitted fabrics according to the present invention will be described in detail.

A is a flat foil yarn used in the present invention, and the flat foil yarn A has a structure in which a synthetic resin film on which aluminum or other metal is vapor-deposited, such as a vinyl chloride film, is laminated on both the front and back sides of Japanese paper 1. is used.

At this time, the metal vapor-deposited film 3 has its vapor-deposited layer 2 side covered with Japanese paper 1.
They are arranged from the front and back so that they are brought into contact with each other.

The flat foil yarn A is obtained by cutting a flat foil material having the above structure into threads having a width of 0.2 to 0.4 mm using a slitter or the like.

The film used in the present invention may be any type of film as long as it is capable of so-called metal vapor deposition, and the film may be colored. If a transparent colored film is used, , it is possible to develop a metallic tone with that color tone.

B is a special gold and silver thread according to the present invention, and the special gold and silver thread B
The flat foil yarn A having the above structure is used in an even number of 4 or more, more specifically a multiple of 4, and is made into a round cord braid such as a 4-strand braid, a 8-strand braid, or a Karauchi braid. A round special gold and silver thread B is formed by braiding the threads into a braided cord.

This special gold and silver thread B is a fiber with extremely excellent reflective luster and closely resembles a pseudo-sewn texture in appearance.

(Effects of the Invention) According to the present invention, the gold and silver flat foil thread uses Japanese paper as a so-called core material, and since it is a special gold and silver thread that is assembled into a braided cord, the gold and silver thread can be used to fabricate a desired obi or other fabric. When woven on the ground, the washi paper does not stretch due to tension,
However, by assembling it into a braid, the diffused reflection due to the refractive index becomes noticeable, and the cross-section of the flat foil thread, which is the washi paper part, gives the appearance of a pseudo-woven weave, resulting in a gold and silver thread with extremely high brightness. Become.

Furthermore, compared to conventionally well-known twisted yarns, it maintains extremely soft properties, so it has the advantage of being finished in a flexible manner, prevents untwisting, and eliminates peeling of the foil portion at the same time.

Furthermore, since it is assembled with flat foil threads, unlike gold and silver threads assembled with round threads, it has the advantage of exhibiting a remarkable metallic luster and being able to be manufactured at a low cost.

Claims (1)

[Claims] It is characterized by flat foil threads made by laminating metal vapor-deposited films on both sides of washi paper with vapor-deposited layers on the inner surface, which are braided in an even number of four or more to form special round gold and silver threads with a pseudo-bound texture. Special gold and silver thread for woven and knitted fabrics.
