Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to twisted gold and silver threads that are flexible and have excellent metallic luster, and a method for producing knitted and woven fabrics using the same.

Traditionally, twisted gold and silver threads have been used as (a) round twisted threads in which gold and silver threads are wrapped around the core thread so that the core threads are not visible; 3 for foil thread
It is known that the bellows twisted thread is wound so that it is ~5 times as large.

The gold and silver thread in (a) has an appearance similar to wire or metal thread, so when a precise design is woven with this thread, the design is finished in a solid gold and silver color.

However, since this thread has a high number of twists, it has great crimpability, and is relatively effective for thick fabrics such as flags, bookmarks, obi fabrics, etc., but thin fabrics such as georgette, etc. This method is difficult to apply to knitted fabrics such as tie fabric or jersey.

This is because when thin fabrics are eluted, the threads that form the fabric are soft and thin, so the crimpability of gold and silver threads prevails, and the woven fabric tends to crimp in one direction, making it difficult to make a homogeneous product. The used parts have a hard finish, which destroys the unique texture of thin fabrics.

On the other hand, the gold and silver thread in (b) is soft and has a twist of ・p
Because of this, it has weak crimp properties and can be woven and knitted uniformly, making it suitable for thin fabrics for clothing. However, because the twist is low, it is easily damaged by friction during weaving or knitting, and because it does not synchronize with the shrinkage of the fabric, it is likely to cause floating of the gold and silver threads and breakage of the threads. Furthermore, it lacks a gold-silver color tone and a heavy feel, so although it can be used effectively for ground texture to some extent, no design effect can be expected even when used for pattern parts.

The present invention eliminates all of these drawbacks and provides a twisted gold and silver thread that has the appearance and strength as shown in (a), and is flexible and less crimpable as shown in (b).

Furthermore, the present invention also provides a method for producing knitted and woven fabrics with excellent design effects and good texture by using the new twisted gold and silver threads.

The twisted gold and silver thread of the present invention is obtained by first twisting the core thread, then twisting the core thread in the opposite direction to the core thread (ply twist), and wrapping the flat foil thread around it. The twist of the first twist is 1.
It is characterized by being 0 to 14 times larger.

The twisted gold and silver thread of the present invention has a core yarn twisted in the opposite way to the twisting of the flat foil thread, so even if the flat foil thread is tightly wound, it has little crimpability and is flexible. It becomes a thread.

For example, the final twist of round twisted yarn is usually around too many times/m, but in the present invention, the core yarn is first twisted in the opposite direction with the same or slightly lower twist, so it has the appearance of (a). Even if there is, for example, the difference between the first twist and the first twist is 100 to 40
If the twist is 0 times 7 nt, the twisted gold and silver thread has a twist degree of about 100 to 400 times/m, that is, the twisted gold and silver thread has the same crimpability and texture as the twisted gold and silver thread of ←).

The difference between the top twist and the bottom twist is 20~30'! It is particularly preferable that it is about 4.

In addition, the core thread is generally made of natural or synthetic fiber.
It is preferable that 100 denier ordinary yarn is used, that it is a twisted or multifilament yarn, and that it is first twisted at a rate of 500 times/m or more.

In addition, as the flat foil thread, any of those used for ordinary twisted gold and silver thread can be used, but by using one whose back side is provided with unevenness or a water-soluble resin coating by emponu processing, etc. It is also possible to create a product with a good texture by providing a gap between the core thread and the flat foil thread. Water soluble (!+: The resin coating is eluted during water treatment during scouring of gold and silver threads or textile fabrics using the same, resulting in the formation of voids.

Next, in the present invention, two types of twisted gold and silver threads are prepared with the twist direction reversed, and by using these as a pair, a knitted fabric with an unprecedented design effect and good texture can be manufactured. can.

That is, the core yarn a1 is given a left-handed first twist, and the core yarn a1
The twisted gold and silver thread A is made by wrapping the flat foil thread b1 with a right-handed ply twist, and the core thread a2 is wrapped with a right-handed ply twist.
A twisted gold and silver thread B is prepared by winding a flat foil thread b2 with a left-handed ply twist, and the twisted gold and silver threads A and B are used by distributing them in pairs. Also in this case, as described above, the twist degree of the first twist is preferably 1.0 to 1.4 times the twist degree of the first twist.

For example, by knitting or weaving the twisted gold and silver threads A and B, or by alternately weaving or knitting the twisted gold and silver threads A and B, the crimpability of the twisted gold and silver threads A and B can be reduced by Furthermore, it is offset and the surface is smoothed, resulting in a soft fabric.

Of course, the twisted gold and silver threads A and B may be used together with ordinary threads, and a large number of ordinary threads may be interposed between the twisted gold and silver threads A and B.

Note that the core yarns al and a2 and the flat foil yarns b1 and b2 may be made of the same material or different materials, but it is preferable that their thickness and twist degree are the same. stomach. Moreover, three or more types of twisted gold and silver threads of the present invention may be used in combination.

Next, examples of the present invention will be shown.
1) A 50 denier nylon left-handed twisted 800 times/m was used as a core yarn, and a flat foil yarn (polyester film/silver vapor deposited film) with a width of l/35cy1 obtained by the method described in Japanese Patent Publication No. 56-41712 was used as a core yarn. / Protective pattern, ・'Polyvinyl alcohol coating color flat foil yarn) right twisted 1000 times/7n
Then, exchanged silver thread A was obtained.

(11) Except for reversing the direction of the first twist and the second twist (+)
Exchanged silver thread B was obtained in the same manner as above.

0li1 28. , '8 raw silk was warped to 60 cm at a density of 80 wood/1. A floral design device is installed, and the cashed silver threads A and I3 are prepared using 28/3 raw silk as the ground weft, and the cashed silver threads A and B are woven alternately into the ground weft - back and forth, and the floral pattern is woven. I got the cloth.

When this woven fabric was subjected to the usual silk scouring process, the slight crimpability of the silver thread resulted in a dress fabric with a beautiful floral pattern that was very pleasant to the touch and had slight silver wrinkles. At the same time, the polyvinyl alcohol coating on the flat foil yarn is eluted during the scouring process, resulting in a product that is more flexible and light than ever before.

Example (2) Two types of yarns, 42/2 worsted yarn and cashed silver yarns A and H, were aligned and knitted using a stockinette knitting machine, and then dyed with a black acid dye at 95° C. for 130 minutes.

The resulting knitted fabric was a homogeneous fabric suitable for sewing, with almost no difference in crimpability observed between the wool and the cashed silver threads A and B, with a subdued gold and silver color scattered throughout.

Example 13] Gold-colored redeemed silver thread A' and silver-colored redeemed silver thread B' were obtained by the methods (1) and (11) above. Separately, prepare threads of 80/2 nylon twisted 300 times/m to the left and threads twisted 300 times/m to the right, and combine these two types of nylon threads with cashed silver thread A,',
Warp the warped products by lining them up alternately.
A type of nylon thread and two types of gold and silver threads are alternately woven as weft threads, and the resulting woven fabric is treated with hot water.3 The product is smooth and flexible because the crimpability of the nylon thread and the gold and silver thread are almost the same. The result is a beautiful fabric with a glaring property that appears to be silver or gold plain depending on the viewing direction.
