Description

DETAILED DESCRIPTION OF THE INVENTION [Objective of the Invention (Industrial Application Field) The present invention relates to a special shape-recoverable yarn that can restore its shape to its original shape by heat, and a fabric using the yarn.

(Prior Art) Conventionally, metal foil threads made of simple gold, silver, etc. have been known as foil threads. This known metal foil thread is made by coating Japanese paper or film with metal foil such as gold or silver and roughly cutting it into narrow pieces.

When these foil threads are actually used in textiles.

Silk thread, silk spun yarn, or thermoplastic synthetic lIM filament such as nylon or polyester lIM is used as the core yarn, and the above-mentioned foil yarn is used as the sheath yarn to form a composite yarn.

However, these composite foil yarns have the disadvantage of poor recovery and elasticity, so even when fabrics using these composite foil yarns, especially obi fabrics, have poor recovery properties.

Poor elasticity. Therefore, for example, when this fabric is sewn into a belt and used, it is extremely difficult to restore the original state of wrinkles and creases that occur during use.

In order to restore these wrinkles and creases to their original state, special yarns using shape memory alloys and shape memory resins are being developed. For example, a special foil yarn has been developed in which gold, silver, or other foil is pasted with an adhesive to a fabric that uses shape memory filaments in the warp and weft yarns, and then shaped into narrow widths.

(Problems to be Solved by the Invention) By the way, in order to make the special foil thread that is being developed light and thin, if a thin shape memory filament is used, there is a drawback that the thread is likely to break.

In addition, since the shape memory filament is made of, for example, a shape memory alloy, there is a problem in that it requires very advanced technology and is very difficult to apply foil to the surface of the filament.

Furthermore, since the foil is also metal, the obtained special foil thread is very hard, and when it is driven into the surface of the fabric, it remains very hard, causing problems with the joining surface of the fabric.

The purpose of this invention is to solve the above-mentioned problems by using a special shape-recoverable yarn and its yarn, which eliminates yarn breakage, can be easily foiled, and eliminates the hardness of the texture of the fabric as much as possible. Our goal is to provide quality textiles.

"Structure of the Invention" (Means for Solving the Problems) In order to achieve the above object, the present invention includes bonding a woven fabric to at least one surface of a film-like shape memory plate,
This is a special shape-recoverable yarn made by cutting this into narrow pieces.

Further, the present invention is a woven fabric obtained by weaving the above-mentioned shape-recoverable special yarn so as to be exposed at least on the surface of the woven fabric.

(Function) By employing the special shape-recoverable yarn of the present invention and the fabric fabric using the yarn, wrinkles, creases, etc. can be easily removed since the yarn has shape-recovery properties. Also,
The special thread is made by pasting woven fabric onto film-like shape memory plywood, making the shape memory plywood as thin and light as possible.
In addition, thread breakage can be reduced, foiling, etc. can be easily performed, and a texture with less hardness can be achieved.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

Referring to FIG. 2, a shape memory alloy 1 such as a T-Ni alloy as a shape memory plate is formed into a thin film, and at least one surface of the shape memory alloy 1 is coated with adhesive or resin material, etc. Attach 3. For example, this fabric is 1
A plain-woven silk fabric using silk threads of about 5 to 50 denier as warp threads and weave threads.

A metal foil 5 of, for example, gold or silver is applied onto the fabric 3. Instead of this metal foil 5, painting or transfer printing may be used. Dough 7 thus obtained
When cut into a narrow width of, for example, about 2 to 311 mm, a shape-recoverable special foil thread 9 as a shape-recoverable special thread is obtained as shown in FIG.

In this way, since the shape-recoverable special foil yarn 9 is formed into a narrow width 1a by bonding the fabric 3 to the shape-memory alloy 1, the shape-memory alloy 1 can be made thinner and lighter.

In addition, since the fabric 3 is bonded to the shape memory alloy 1,
Since the bending strength is increased, thread breakage can be reduced, and the shape-recoverable special foil thread 9 can be easily handled.
The texture can also be made closer to that of silk, for example. Furthermore, since the metal foil 5 of gold, silver, etc. is not directly foiled onto the shape memory alloy 1, but is foiled onto the fabric 3, foiling can be performed simply and easily.

In addition, since the shape-recoverable special foil yarn 9 has the shape-memory alloy 1, even if it is deformed into a bent state by external force, it can be heat-treated at a certain temperature, for example, about 40 to 60 degrees Celsius. As a result, the shape-recoverable special foil yarn 9 recovers three-dimensionally easily and easily in both the longitudinal direction and the direction perpendicular to the longitudinal direction, and therefore has extremely excellent recovery properties and elasticity. Of course.

The shape-recoverable special foil yarn 9 thus obtained is applied to the warp yarn, the weft yarn, or both the warp yarn and the weft yarn so that it is exposed at least on the surface of a silk fabric using silk yarn for the warp yarn and the weft yarn, for example. As shown in Figure 3 (when you type in, you will receive 100 silk
It can be made into a luxurious woven fabric of 11%. This woven fabric 11 can have a texture similar to that of silk and has flexibility.

Further, if the fabric 11 is sewn into a band, for example, even if wrinkles or creases occur, they can be simply and easily removed by heat treatment at, for example, about 40 to 60°C.

Instead of the shape-recoverable special foil thread 9, if a special shape-recoverable thread that has been painted or transfer-printed is inserted so that it stands out on the surface of the woven fabric 11, this pattern will be reproduced on the surface of the woven fabric 11, resulting in an attractive appearance. You can get something rich in luxury.

In this embodiment, the fabric 3 is bonded to one surface of the shape memory alloy 1, but the fabric 3 may be bonded to the other surface.

Note that the present invention is not limited to the embodiments described above, and can be implemented in other embodiments by making appropriate changes. For example, in this example, a shape memory alloy was used as a shape memory plate, but polynobornene may be used as an example. Shape memory resin or the like may also be used.

[Effects of the Invention] As can be understood from the above description of the embodiments, according to the present invention, a woven fabric is pasted on at least one side of a film-like shape memory plywood, and this is cut into narrow widths. Because it is a shape-recoverable special yarn obtained by Since it can be easily and easily restored to its original state in a short time, it has excellent three-dimensional recovery properties and elasticity.

In addition, the shape memory plywood can be made thinner and lighter, and because it is bonded with a woven fabric, it becomes a shape-recoverable special thread that does not break. Moreover, the texture of the yarn is improved in hardness and can be brought closer to the original texture of the yarn.

The woven fabric of the present invention can be fabricated by weaving the shape-recoverable special yarn so as to be exposed on the surface of the fabric, so that the shape-recoverable special yarn can be coated with foil, painted, or transfer-printed. If this is done, the foil or pattern will appear and be reproduced on the surface of the woven fabric, making it possible to create a woven fabric that is luxurious and luxurious and has a good appearance.

Also, if this fabric is used as a belt, for example,
Even if wrinkles or creases occur, they can be removed simply and easily and in a short time by applying heat treatment at a certain temperature.
