[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a garment shape retention core material used for shoulder pads, chest pads, etc. in order to maintain the shape of clothes or improve the silhouette of the body shape.

[0002]

[Prior Art]

 In order to maintain the shape of clothes, shoulder pads and chest pads in which a core material is inserted into the shoulders and chest of clothes are widely used. In other words, this core material functions as a shaping material that is attached to clothes and adjusts the body shape, is more elastic and shape-retaining than the cloth of clothes, and is in the form of a flat core cloth on the required part. There are those used, such as a frame for adjusting the outer shape of clothes, for example, a wire used for the outer circumference of clothes to maintain the edge shape.

Clothes for manipulative type, which are equipped with such a core material and which are worn in a manner to be in close contact with the human body in order to correct the body type, such as chest pads, brassieres, corsets, girdles, body suits, etc. In this case, as a result of the core material functioning as a shaping material, the garment applies stress to the human body to shape the body shape, but in the case of the wire material that is conventionally used as the core material, only normal elastic deformation is applied. Therefore, when the deformation of the core material increases with the movement of the human body, such as during exercise, a large return force is generated, which gives a strong stress to the human body, causing pain and pain to the user. It was

[0006] Fiber cotton, non-woven fabric, polyurethane sheet, or the like may be used as a core material, but they have a drawback that they do not return to their original shape when they lose their shape, and they are not lightweight.

In order to eliminate the above-mentioned drawbacks of the shape-maintaining core material, it has been proposed to use a shape-maintaining core material using a shape memory alloy such as a nickel-titanium alloy. That is, as a characteristic of the shape memory alloy, firstly, even if it is deformed with a desired stress at a temperature below the martensite positive transformation temperature, when it is heated above the martensite reverse transformation temperature, it returns to its original shape as a parent phase. There is a shape memory effect. Secondly, stress-induced martensite is generated by applying stress above the martensite reverse transformation temperature, and under this stress, it withstands a large strain of several% to ten and several%, and after applying this large strain, the stress is increased. It has a superelastic effect that returns to the original matrix shape when removed.

Among the characteristics of such a shape memory alloy, the stress state, particularly in the superelastic effect region, is the most suitable as the characteristics of the core material for shape retention, and is a large metal that does not return to its original shape while deformed. Even at the time of deformation, it returns to its original state without leaving any strain in the superelastic region of the shape memory alloy. Moreover, in the case of ordinary metal, the greater the amount of deformation, the greater the opposing force, which exerts a greater force on clothes and the body.On the other hand, in shape memory alloy, even if the amount of deformation increases, the opposing force does not increase. It does not give any deformation force to clothes, especially the body, does not give pressure or pain to the user, and is lightweight.

Further, among the characteristics of the shape memory alloy, even if it is deformed at any temperature below the transformation temperature, it is restored to its original shape by raising the temperature above the transformation temperature, so that the water temperature is set below the transformation temperature. This makes it possible to freely wash clothes without paying special attention when washing them, and when used, it naturally returns to its original shape, providing optimal properties as a core material for clothes.

[Problems to be solved by the device]

 The shape-maintaining metal core for garment shape retention is a material of particular interest because it has various excellent properties as a core as described above, but when using it as an actual core, There are many challenges to be solved in.

That is, when the shape memory alloy material is used for a pad or the like, for example, a finely woven mesh-woven fabric is cut into a desired shape, and the shape is memorized in an arbitrary shape. However, the shape-retaining core material made in this way has fine wire tips protruding around the outer periphery of the mesh-shaped material, and if used as it is as a core material You will be stuck.

Further, the outer periphery of the core material thus formed in a mesh shape is cut into various shapes, and a part of the fine wire forming the outer periphery is frayed and comes off, so Can no longer maintain its shape.

Further, not only the fine lines around the outer periphery but also the fine lines are displaced from each other in all the mesh portions, and a predetermined uniform mesh is not formed. There was also a drawback that it could not be maintained.

Therefore, the present invention does not cause fraying around the outer periphery of the shape-retaining core material formed in a mesh shape, and can surely maintain the mesh shape so as not to cause harm to the user. An object is to provide a core material for shape retention.

[0013]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention relates to a shape-memory alloy garment shape retention core made by weaving a shape-memory alloy fine wire made of nickel-titanium alloy into a mesh shape. Alternatively, the core material is covered with a knit or a woven fabric and trimmed, and at least one side of the core material is covered with a non-woven fabric or a knitted woven fabric. It does not cause fraying, can maintain the mesh shape reliably, and does not harm the user.

[0014]

[Action]

 Since the present invention is configured as described above, the core material for maintaining the garment maintains a predetermined shape during use and maintains the function of the core material, and exerts a great force on the body even when it is greatly deformed. There is no deformation, and it returns to its original shape. In addition, since the intersections of the meshes of the mesh-shaped fine wires are glued together, the thin wires do not shift from each other, and the edges are covered and trimmed, so the wires do not fray and do not harm the body etc. ..

[0015]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. A fine wire of a shape-memory alloy having a ratio of nickel to titanium of 50:50 and having a shape memory alloy of 150 μm has a plain weave structure to form a mesh fabric 1 having a warp and weft density of about 20 mesh. The thickness of the thin wire is appropriately selected within the range of 50 to 300 μm depending on the application. The warp and weft thread densities are set arbitrarily such as 10 to 50 mesh. Further, as the woven structure, a plain weave, a twill weave, a satin weave, etc. may be adopted as necessary.

An appropriate adhesive is applied to the mesh material 1 by coating, spraying, dipping or the like, and particularly to the portion 2 where the fine lines of the history intersect. As the adhesive 3, any adhesive such as starch, polyvinyl acetate, PVA, polyvinyl chloride, ester of polyacrylate, phenol, urea, melamine, polyester, polyurethane, etc. can be used. .. When applying these adhesives to the mesh fabric, any means such as coating, spraying, dipping, etc. can be adopted, and by these means, these adhesives also adhere to the vertical and horizontal intersections of the mesh fabric and The materials will not shift from each other. In selecting the adhesive, it is necessary to use a material that does not melt or evaporate during the high temperature treatment of the mesh material described later, and heat resistance and thermosetting resin are suitable in that respect.

The mesh material 1 coated with the adhesive is cut into a shape corresponding to various pads. At this time, since the meridian lines and the weft lines of the wire rods at the cutting edge are fixed to each other with an adhesive, it is possible to prevent the wires from fraying and coming apart from the cutting edge.

The mesh material cut into a predetermined shape is deformed into a predetermined shape at a predetermined temperature corresponding to a desired temperature at which a martensitic transformation in a shape memory state occurs, and the shape is memorized. For example, when the desired temperature for causing the martensitic transformation is desired to be 25 ° C. to 40 ° C., heat treatment is performed at 425 ° C. and the shape is memorized in a predetermined shape.

The desired temperature for causing the martensitic transformation is set in consideration of the environment in which the shape-retaining member is used. For example, when the shape-retaining member is used as a shoulder pad, normal warming is performed. Considering that the temperature inside the clothes when worn under various conditions is 31 to 32 ° C, about 25 ° C is selected.

A peripheral edge portion of the shape-meshed mesh material is covered with a band material 5 made of a non-woven fabric, a knitted material, and a woven material, and sewing 4 is performed to form a trimmed peripheral edge covering portion 6. The peripheral edge covering portion 6 prevents the fine wire around the mesh ground from piercing a human body or the like.

If necessary, a surface coating material 7 made of a non-woven fabric, a knitted fabric or a woven fabric may be provided on one side thereof, and the surface coating material 7 may be provided on only one side or both sides. As a result, it is possible to increase the bulkiness or prevent the metal core material from fitting into the inside of clothes and coming into direct contact with the human body.

When the shape-retaining core material using the shape memory alloy as described above is used for clothes, for example, when the clothes are deformed by hanging on a hanger, or when the clothes are deformed by washing, When this is worn, the temperature of the shape memory alloy rises due to body temperature, martensitic transformation occurs, and the original memory shape is restored.

Furthermore, even when stress is applied to clothes due to vigorous movements of the body during wearing, the clothes are restored to their original condition when the stress is removed, and when the stress is applied, the clothes are flexibly deformed. Even when it is used in a portion that comes into direct contact with the body, such as during use, it does not exert a large force against the body against deformation.

[0024]

[Effect of the device]

 Since the present invention is configured and operates as described above, it is a unique effect of the shape-retaining core material using a shape memory alloy, that is, even if the clothing is deformed, it can be restored to its original shape and worn. Even if a large force is applied to the inside, it will not be deformed flexibly and will not cause pain and pain to the user, and in addition, by using a material woven with fine wires in a mesh shape, three-dimensional It is possible to maintain the precise shape of the surface shape. In addition, since the adhesive is applied to the intersection of the mesh-shaped core material, the deformation of the shape due to the misalignment of the wire materials can be prevented, and when the mesh-shaped core material is cut, the thin wires on the periphery are frayed. Can be prevented. Furthermore, since the peripheral edge of the core material is covered with a non-woven fabric or a knitted fabric and trimmed, the thin wire around the peripheral edge of the core material does not pierce the human body or the like, which is safe. Therefore, it can be widely used as a shape-retaining material for shoulder pads, chest pads, etc. of outer garments, and for underwear for manipulative type.

By covering at least one surface of the core material with a non-woven fabric or a knitted fabric, the shape-retaining core material does not feel uncomfortable even if it comes into contact with the cloth and has a good feel on the skin. Becomes
