Description

[Detailed Description of the Invention] The present invention relates to twisted gold and silver threads that are irregularly dotted with foil patterns, easy to handle, and have a good texture.

Conventionally, twisted gold and silver threads include round twisted thread A in which flat foil thread 1 is wound around core thread 10, hagoromo twisted thread B and bellows twisted thread C1, and entangled twisted thread and sash twisted thread E in which thin thread 11 is entwined with flat foil thread 1. is known.

However, all of these are manufactured using the surface condition of flat foil yarn 1 as is to create a strong product suitable for weaving, and the ordinary yarn is simply used as a core yarn or reinforcing yarn. .

Therefore, all gold and silver threads have a water-like or wire-like appearance with a regular metallic luster, which alone cannot be said to be an attractive product, and they also have the disadvantage that they tend to untwist from the cut surface.

Furthermore, in those products, high-quality twisted gold and silver threads cannot be obtained with single-sided flat foil yarns having metal foil on only one side, and twisted yarns A, B, and C in which flat foil yarn 1 is wound around core yarn 10 However, defects are likely to occur due to the occurrence of back-up.

The present invention, unlike such conventional products, provides a stable twisted gold and silver thread with good texture that can be used alone as an attractive knitting or weaving thread.

The twisted gold and silver thread of this invention consists of a flat foil thread 1 and two ordinary threads 2 and 3.
The ordinary yarn 2 is irregularly twisted around the flat foil yarn 1 to form the twisted yarn 4 (see Figure 2 A), and the ordinary yarn 3 is twisted on the twisted yarn 4 in the opposite direction to the ordinary yarn 2. It is characterized by being irregularly twisted (see Figure 2B).

As the flat foil yarn 1 in the present invention, any general material such as foil paper, colored paper, astringent paper, metallized sheet, etc. cut can be used, and it may be a double-sided flat foil yarn or a single-sided flat foil yarn.

In particular, in this invention, since the twists are irregularly applied,
When using a flat foil yarn with different colors on both sides, the front and back of the flat foil yarn 1 and the two ordinary yarns 2.3 are effectively mixed and exposed on the surface,
It has an excellent decorative effect.

A typical type of flat foil yarn with different colors on both sides is single-sided flat foil yarn, which has metal foil and a protective film on the surface of the washi paper.By using this type of yarn, a product of particularly high quality can be obtained, and the effect of piece dyeing can be improved. You can also expect

Next, the two ordinary yarns 2 and 3 may be either filament yarns or spun yarns, and may be of the same type or different types.

Typically, spun yarn or less twisted filament yarn is used.

Further, the thickness of the base yarn is not particularly limited, but it is preferable that the flat foil yarn 1 serving as the core yarn in the present invention has a width of 0.10 to 25 mm, particularly about 0.15 to 0.20 mm. The thickness of the ordinary thread to be twisted together is preferably about 30 to 80 denier, particularly about 40 to 60 denier.

The degree of twist of the flat foil yarn 1 and the ordinary yarn 2 and the degree of twist of the twisted yarn 4 and the ordinary yarn 3 can be arbitrarily selected as necessary, but generally they are 400 to 8.
00 times/m is preferable.

Further, it is preferable that the twist degree of the latter is less than that of the former.

In this invention, since the flat foil yarn 1 is used as the core yarn and the relatively thick ordinary yarns 2 and 3 are twisted together once in an irregular manner, roughness due to the sides of the flat foil yarn 1 may occur on the surface. Even when woven entirely as a ground weft, there is no pattern or pattern pattern caused by the weaving steps or the common multiple of the twist and weave, as in the past, and it has a very good texture. It becomes gold and silver thread.

Furthermore, it is difficult to untwist, and can be effectively used in fields where abrasion resistance is required, such as warp threads of woven fabrics, sewing threads, and lace threads.

The twisted gold and silver thread of the present invention can be manufactured by the method shown in FIG.

First, in FIG. 3A, the flat foil yarn 1 is wound around the bobbin 5, and the regular thread 2 is wound around the bobbin 6.

The bobbin hole 8 of the bobbin 5 is formed to be considerably larger than that of the bobbin shaft 7, and the bobbin 5 is eccentrically centered due to the attachment of the balancer 9.

The flat foil yarn 1 passes through the guide 16 and the axis of the flyer 12 and is twisted with the ordinary yarn 2 above the flyer 12.

The flyer 12 is rotated in one direction by a belt 13, thereby determining the direction of twisting.

Until the balancer 9 moves from directly below the bobbin 5 to the left side and reaches directly above the bobbin 5, the flat foil thread 1 is maintained at a constant tension between the bobbin 5 and the guide 16, and the thread is joined to the common thread 2. is located at the X position, and forms a twisted yarn 4 in which ordinary yarns 2 are twisted together using the flat foil yarn 1 as a core yarn.

Next, when the balancer 9 moves from directly above the bobbin 5 to the right side, the balancer 9 momentarily falls directly below the bobbin due to its gravity, so the bobbin 5 rotates at a speed faster than the rotation of the winding device (not shown). It will be turned once, and the flat foil thread 1
is relaxed at the position of the guide 16, and the joining point with the ordinary yarn 2 moves to the Y position because the centrifugal force of the ordinary yarn 2 acts strongly.

The twisted yarn 4 obtained in this case has a shape in which flat foil yarns 1 are twisted together with the ordinary yarn 2 as the core yarn.

In this way, in the method shown in Figure 3, by repeating the shape in which the flat foil yarn 1 becomes the core yarn and the ordinary yarn 2 becomes the core yarn, the ordinary yarn 2 is irregularly twisted around the flat foil yarn 1. A twisted yarn 4 is formed.

Therefore, even if a single-sided flat foil yarn having a metallic color or coloring on only one side is used, the twisted yarn 4 will have a pattern on both sides without causing so-called back twisting.

The twisted yarn 4 thus obtained is guided above the flyer 12 from the bobbin 14 in FIG.

Here, the same method as in the manufacturing of the twisted yarn 4 is carried out except that the direction of movement of the flyer 12, that is, the rotating belt 13 is reversed from that shown in FIG. 3A.

However, it is better to control the rotational speed of the flyer 12 to reduce the degree of twist than in the previous case so that the surface of the twisted gold and silver thread that is the product becomes flat.

Gold and silver threads with irregular brightness are already obtained as twisted yarn 4 in the first stage, but since this is further coated with ordinary yarn 3 in an irregular twist tone, the brightness is extremely reduced, making it extremely The result is gold and silver thread with elegant brightness.
