JPH05156537A - Production of twisted yarn made of pure gold and twisted yarn - Google Patents

Abstract

PURPOSE:To obtain the subject twisted yarn suitable for accessories to a dress such as sash clip, having excellent breakage resistance and restoration free from orientation by cutting extra fine pure gold in length, firstly twisting the cut wires. CONSTITUTION:Extra fine pure gold wires 1 to 3 having 20-60mum diameter are cut in length determined for sash clip or other many articles, twisted as first twisting by a twister 20-30 times, three or more of the firstly twisted wires are arranged and further twisted by a twister approximately half of the times of the first twisting to give the objective twisted yarn 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention uses an ultrafine wire made of pure gold to make a braid, a braid, a braid, which is used for garment fastening such as obi fastening, obi fastening, and other crafts such as boxes, musical instruments and foreheads
The present invention relates to a method for producing a twisted yarn that can be used as a bag-like string, other cords, and the like, and a twisted yarn produced by this method.

[0002]

2. Description of the Related Art Conventionally, silk threads have been the main thread used for braids, bait strings, etc.
In addition, some products were found to incorporate gold threads, silver threads, etc.

[0003]

However, there is no example of a braid, a striking cord or the like which is made up entirely of fine wires made of pure gold because of the breaking load and elongation of pure gold. However, it is not well known for its high price. On the other hand, due to the rapid development of electronic equipment products, connection of semiconductor elements etc. is expensive but electronically stable gold and silver,
Many precious metals such as nickel are used and are now sold as bonding wires.

An object of the present invention is to provide a method for producing a twisted yarn which can be made into a braid, a braid, and other products by using an ultrafine pure gold wire such as a bonding wire, and a twisted yarn produced. is there.

[0005]

In order to achieve the above object, the present invention is, in the first invention, an ultrafine wire made of fine gold having a diameter of about 20 to 60 μm and having a length determined by obi fastening and other products. After cutting and twisting as a lower twist on a twisting machine for about 20 to 30 rotations, align 3 or more of these twisted twisted yarns, and apply again to the twisting machine to twist the twisted wire about half the number of times of the final twist of pure gold. The manufacturing method was used.

In the second aspect of the present invention, the twisted yarn produced by this production method comprises a plurality of undertwisted pure gold wires, and is subjected to overtwisting about half the number of times of undertwisting. Twisted yarn made of pure gold.

[0007]

[Function] For a wire made of pure gold with a length of 20 to 60 μm cut into a length suitable for band tightening and other products,
By twisting about 20 to 30 rotations using a twisting machine, the strength of the raw yarn against the breaking load is improved,
% Elongation has occurred. This twisted yarn has a tendency to wind in a spiral when the traction is relaxed.

Next, three or more of these under-twisted wires are gathered and again twisted by a twisting machine about half the number of times of the above-mentioned twisting, so that a spiral shape is formed during the above-mentioned twisting. The wires gather to form a straight line,
It was able to be stably bent in any direction of 360 degrees and a restoring force was generated. The twisted yarn manufactured by the above-described manufacturing method can be tied and unwound in the same manner as natural fibers, synthetic fiber, etc., and can be finished into a braid, a braid, a braid, etc.

[0009]

[Embodiment] An example of manufacturing a band clamp will be described below as an embodiment. Bonding wire (made of pure gold) diameter 40 ~ 55μ
m, length 150 cm, width 1.5 cm. Twist 26 twists (bottom twist) for one strand using a manual twisting machine. Three strands were put together and twisted 13 times (upward twist).

The number of revolutions by the twisting machine varies depending on the diameter of the fine wire made of pure gold, the required length and the number of incorporated wires.

[0011]

INDUSTRIAL APPLICABILITY The present invention provides a twisted yarn which uses a fine wire made of pure gold and is twisted twice to enhance the breaking resistance, have no directionality, and can be restored. I was able to do it. That is, in the ply-twisted thread, one thread that tends to have a spiral shape is
By twisting more than one book together, not only this tendency is eliminated, but also the breaking resistance is strengthened, and it becomes possible to incorporate it as a braid, a braid, or a braid.
