Description

Description: [Object of the Invention] (Field of Industrial Application) The present invention relates to a shape-recoverable special yarn that can restore its shape to its original shape by heat and a woven fabric using the yarn.

(Prior Art) Conventionally, as a foil thread, a metal foil thread made of simple gold, silver or the like has been known. This known metal foil thread is made by drawing a metal foil of gold, silver or the like on Japanese paper or a film and then cutting it into a narrow width.

When these foil yarns are actually used for textiles, a silk yarn, a silk spun yarn or a thermoplastic synthetic fiber filament such as nylon or polyester fiber is used as a core yarn and a composite yarn using the above-mentioned foil yarn as a sheath yarn. To use.

However, since these composite foil yarns have the drawback of poor recovery and elasticity, even the fabrics using these composite foil yarns, especially the strips, have poor recovery and elasticity. Therefore, for example, when this woven fabric is sewn into a belt and used, it is extremely difficult to restore wrinkles, creases, and the like generated during use to the original state.

In order to restore these wrinkles and creases to their original state, a special yarn using a shape memory alloy or a shape memory resin has been developed. For example, a special foil yarn has been developed in which a woven fabric using shape memory filaments for each of the warp yarn and the weft yarn is attached with a foil of gold, silver, or the like with an adhesive and is cut into a narrow width.

(Problems to be Solved by the Invention) By the way, this special foil yarn that is being developed has a drawback that if a thin shape memory filament is used in order to thin the shape lightly, the yarn is easily broken.

Further, since the shape memory filament is made of, for example, a shape memory alloy, there is a problem that it is very difficult to foil the foil on this surface because it requires a very high technique.

Further, since the foil is also a metal, the obtained special foil yarn is very hard, and when it is struck on the surface of the woven fabric, it remains very hard, which causes a problem in the texture of the woven fabric.

An object of the present invention is to use a shape-recoverable special yarn which eliminates yarn breakage, allows easy foiling, etc., and removes hardness as much as possible from the texture of the woven fabric, in order to improve the above-mentioned problems, and a yarn thereof. The purpose is to provide the woven fabric.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention is to bond a woven fabric to at least one surface of a film-shaped shape memory plate,
It is a shape-recoverable special yarn obtained by cutting this into a narrow width.

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

(Operation) By adopting the shape-recoverable special yarn of the present invention and the woven fabric using the yarn, since it has the shape-recovery property, it is possible to easily remove wrinkles and creases. Further, since the special thread is formed by laminating a woven fabric on a film-shaped shape memory plywood, the shape memory plywood can be made as thin and light as possible, and thread breakage can be reduced to facilitate foiling and the like. It is possible to obtain a texture free from hardness.

(Embodiment) An embodiment of the present invention will be described in detail below with reference to the drawings.

Referring to FIG. 2, a shape memory alloy 1 such as a Ti-Ni alloy as a shape memory plate is formed into a thin film, and at least one surface of the shape memory alloy 1, for example, the surface is woven with an adhesive or a resin material. Stick 3 together. This woven fabric is, for example, a plain woven silk fabric in which silk yarn having a denier of about 15 to 50 is used as warp and weft.

On this woven fabric 3, a metal foil 5 of gold, silver or the like is foiled. Instead of the metal foil 5, painting or transfer printing may be performed. Dough 7 thus obtained
Is cut into a narrow width of, for example, 2 to 3 mm to obtain a shape-recoverable special foil yarn 9 as a shape-recoverable special yarn as shown in FIG.

In this way, since the shape recoverable special foil yarn 9 is formed by laminating the woven fabric 3 on the shape memory alloy 1 and cutting it into a narrow width, the shape memory alloy 1 can be made thin and light. Further, since the woven fabric 3 is bonded to the shape memory alloy 1, the bending strength is increased, so that the yarn breakage can be reduced, the shape recovering special foil yarn 9 can be easily handled, and the texture is also excellent. The texture of silk can be approximated. Furthermore, since the metal foil 5 of gold, silver or the like is not directly foil-deposited on the shape memory alloy 1 but is foil-deposited on the woven fabric 3, the foil-forming can be performed easily and easily.

Since the shape recovery special foil yarn 9 holds the shape memory alloy 1, even if it is deformed into a bent state due to an external force, it is heat-treated at a certain temperature, for example, a temperature of about 40 to 60 ° C. As a result, the shape-recoverable special foil yarn 9 is three-dimensionally and easily and easily recovered in both the longitudinal direction and the direction orthogonal to the longitudinal direction, and therefore has extremely excellent recoverability and elasticity. Of course.

The shape-recoverable special foil yarn 9 thus obtained is used, for example, in the warp yarn, the weft yarn, or both the warp yarn and the weft yarn so that the warp yarn, the weft yarn, or the weft yarn is at least exposed on the surface of the silk fabric. As shown in FIG.
It is possible to make the woven fabric 11 rich in%. This woven fabric 11 can be made close to the original silk, and has suppleness.

Further, if the woven fabric 11 is sewn into a band, for example, even if wrinkles or folds are generated, it can be easily and easily removed by heat treatment at about 40 to 60 ° C.

If instead of the shape recovering special foil thread 9, a shape recovering special thread that is painted or transferred and printed is struck on the surface of the fabric 11, this pattern is reproduced on the surface of the fabric 11 and looks good. You can get good quality products.

In this example, the woven fabric 3 is formed on one side of the shape memory alloy 1.
However, the woven fabric 3 may be attached to the other surface.

The present invention is not limited to the above-described embodiments, but can be implemented in other modes by making appropriate changes. For example, although a shape memory alloy has been described as an example of the shape memory plate in this embodiment, a shape memory resin such as polynobornene may be used.

[Effects of the Invention] As will be understood from the description of the embodiments as described above, according to the present invention, a woven fabric is attached to at least one surface of a film-shaped shape memory plywood and cut into narrow widths. Since the shape-recoverable special yarn is obtained by applying a heat treatment to some extent, the shape-recoverable special yarn can be bent in both directions orthogonal to the longitudinal direction even if it is bent and deformed by external force. Since it can be easily and easily restored to its original state in a short time, it becomes rich in three-dimensional recovery and elasticity.

In addition, the shape memory plywood can be made thinner and lighter, and since the woven fabric is bonded, it becomes a shape-recoverable special yarn without yarn breakage. Moreover, the hardness of the yarn is improved and the yarn can be made closer to the original texture.

The woven fabric of the present invention is woven so that the shape-recovering special yarn is exposed on the surface of the woven fabric, so that the shape-recovering special yarn is foiled, painted, or transfer-printed. If it is applied, a foil or a pattern appears on the surface of the woven fabric and can be reproduced, so that the woven fabric can be luxurious and rich in appearance and have a good appearance.

Further, if this woven fabric is sewn into a band and used, for example, wrinkles and folds can be easily and easily removed by heat treatment at a certain temperature in a short time.
