Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to gold and silver threads of a special shape that can be used in knitted and woven fabrics in the same way as ordinary threads. Flat foil yarn is well known as a foil yarn, but since it consists of a homogeneous layer throughout, it has an excellent metallic luster, but it has a flat and monotonous appearance, and it is not enough to have a design effect on its own. It wasn't something. Also, if the flat foil thread is not always used straight during knitting, the luster will change drastically and the &! ! Since defects also occur in the woven structure, it has not been possible to freely knit and weave it together with ordinary yarn. Note that ordinary flat foil threads are made of a single layer of Japanese paper or synthetic resin film and have a thickness of 80 to 100 μm.
, is formed with a width of 0.4 to 0.6 mm, is rigid, and has insufficient chemical resistance and other physical properties, so it is difficult to use for ordinary knitted fabrics, especially for those that can be used over the entire surface of knitted fabrics. It wasn't.

Furthermore, there is also twisted gold and silver thread in which a flat foil thread is wrapped around a core thread, but this has rigidity due to the presence of the core thread, and cannot be used for knitting or textiles for clothing. Although there is no need to worry about directionality in the weaving structure, the appearance is monotonous and the design effect is still poor.

Purpose of the Invention The present invention has a suitable metallic luster characteristic of flat foil yarn, while
To provide a very easy-to-handle gold and silver thread that can be used for woven and knitted fabrics as well as ordinary thread.

Structure of the Invention The gold and silver thread of the present invention is made of a foil sheet having a synthetic resin film layer as a base material and having a total thickness of 7μ to 15μ.
The flat foil thread obtained by slitting 1 is slit at intervals of 2 to 6 cm.
It is intermittent twisted with a 6 cm heated section. The foil sheet may have a synthetic resin film layer on only one side of the metal layer, but it is preferable to use a foil sheet in which a synthetic resin film with a thickness of 2.5 μm to 4 μm is laminated on both the front and back sides with the metal layer sandwiched in between. is preferable.

That is, in the present invention, by partially heating an extremely thin flat foil thread with a thickness of 7 μm to 15 μm at appropriate intervals, it is possible to obtain a gold and silver thread that is soft as a whole, has a good texture, and is easy to handle. However, with a flat foil yarn having a normal thickness of 80 to 100 μm, not only is it rigid itself, but it is also impossible to heat only predetermined areas at regular intervals. cannot achieve the goal.

In the present invention, the interval between the heated parts and the length of the heated part may be 2 to 6 cm, but it is particularly preferable that the interval is 3 to 5 cffi; if the interval is too narrow, the yarn will lack flexibility, and conversely If the spacing becomes too large, the strength will decrease. Also, if the length of the heated part is too long, the yarn will lack flexibility.
On the other hand, if the length of the heating part is too short, the strength will be weak.

The width of the flat foil yarn can be heated by the flat foil yarn alone without using the core yarn.
Moreover, in order to maintain the appropriate flexibility and strength of the heated part,
It is limited to 0.6-6 cm. Generally, it is preferably about 1 to 31. However, when obtaining gold and silver thread used alone for rough knitting, it is preferably about 5 to 6III+1.

The degree of twist in the heated part is not particularly limited, but is 100 to 5
00 twists/m, preferably 200 to 300 twists/m.

Intermittent twisting can be applied by a twisting machine equipped with a spindle sudden stop/start device. Preferably, no heat treatment is performed. This causes the heating part to generate heat, but
The flat portion can be kept homogeneous so that the film does not shrink due to high-temperature heating and the gloss does not change accordingly.

Since the flat foil yarn used in the present invention has a metal layer protected by synthetic resin films on both the front and back sides, discoloration of the metal layer is effectively prevented.
No. 7503, Patent No. 1237617, JP-A-57-1
By manufacturing according to No. 95649 or the like, a product with particularly good performance can be obtained.

The flat foil yarn of the present invention, which uses a very thin synthetic resin film, is manufactured by: - After transferring the metal layer provided on a thick sheet to the desired synthetic resin film via an adhesive layer, - Adding a synthetic resin on top of this metal layer. Particularly efficient production is achieved by laminating films together with an adhesive to produce a foil sheet.

In addition, in the above method, by mixing various coloring agents such as dyes into the adhesive, a product with even better design effect can be obtained.

Example [1] Unexamined Japanese Patent Publication No. 57/1956 on a 4μ thick polyester film
The silver thin film treated with No. 49 was transferred via a polyurethane adhesive, the transferred silver thin film was further subjected to the above treatment, and a 4μ thick polyester film was laminated thereon via an adhesive layer.

The foil sheet obtained in this way was cut into a width of 1.5 mm,
The yarn was wound onto a bobbin, heated intermittently by a twisting machine equipped with a spindle sudden stop and start device as shown in FIG. 1, and then heated and then wound into a cylinder.

The spindle (2) of the twisting machine is designed to rotate as the belt (1) moves.The spindle (2) of the twisting machine is designed to rotate as the belt (1) moves. When it is released from the spindle (2), the brake (5) is activated at the same time, and the rotation of the spindle (2) is stopped during that time.The fryer (6) is rotated or stopped in synchronization with the spindle (2). , flat foil thread (7 threads are twisted intermittently, but the cam (8) is in sync with the cam (3))
Since the heating roller (9) is moved back and forth, the product comes out of the guide (lO) and goes into the cylinder (
11), only the heated part is heated by the heating roller (9).
), and the non-heated portion (flat portion) is separated from the heating roller (9) and sent to the cylinder (11) without being heat treated. Heating is approximately 3c at intervals of approximately 4cm.
It was carried out such that there were m heated sections, and the twists of the heated sections were approximately 300 twists/m.

Approximately 50% of the thus obtained silver thread (see Figure 2) in which flat parts (12) and linear heating parts (13) exist alternately is
A plain woven fabric was woven by warping 620 yarns to a width of 0.00 mm, and warping the same number of ordinary yarns, and using these as warp yarns and the same silver threads and ordinary yarns as described above for the weft yarns.

During weaving, the reed feathers are 0.2 mm thick and the interval is 0.
．． 6 mm, but the diameter of the heated portion of the silver thread was approximately 0.6 mm.
3 to 0.50, and the untwisted flat portion passed through the reed feathers in a linear manner, so weaving could be carried out in the same manner as with ordinary yarn. When playing the reed, the flat part becomes diagonal,
Due to the squeezing shape, the heated part maintains a distinct silver luster that is round and linear, and the weft threads also act in the same way, resulting in a rough silver luster that never changes. A fabric with a good pongee-like texture was obtained. Since the ordinary thread is woven parallel to the silver thread in both warp and warp, it exhibits flexibility without being noticeable, and this product could be effectively used as an appliqué material or obi material for clothing.

Example (2) The foil sheet of Example [1] was cut into 5III1 width pieces, and was intermittently heated and heat-set in the same manner as Example [1] to obtain extremely thick silver threads with varying thicknesses. . When lace knitting was carried out using this yarn, a light and soft knitted fabric was obtained that was not much different from yarn of the same thickness. When this knitted fabric was high-pressure dyed with disperse dyes, the degree of dyeing was different between the heated part and the flat part, the heated part and the strongly twisted part and the weakly twisted part, and even the flat part where the twist was bent and the part that was not, and the color was dyed in different shades. This, combined with the change in metallic luster, resulted in a product with a very interesting design effect.

Effects of the Invention The gold and silver thread of the present invention can be woven and woven with good workability in the same way as ordinary thread, and both the flat part and the lightly twisted round linear part have a unique metallic luster. A knitted fabric with excellent design effects can be obtained. In addition, the gold and silver thread of the present invention is very light because it is mainly made of synthetic resin film, and the heated part has no core thread and is thinly twisted in a hollow state, so it has a light knit with a good texture. Textiles can be obtained.
