Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a core material for clothes applied to, for example, girdles, waist nippers and the like.

“Prior art” Girdles, waist nippers, etc. have been conventionally worn to adjust the body line, but in these, a core material is used to adjust the body line and prevent deformation. Has been. As such a core material, for example, a metal, a synthetic resin, a plate material such as paper, or a wire is used.

As the metal core material, wire material or plate material such as stainless steel and shape memory alloy is used. The stainless core material is
It has high rigidity and has a drawback that it gives a feeling of strangeness when worn. On the other hand, if the transformation temperature of the core material of the shape memory alloy is set to room temperature or lower, no matter how much it is deformed at room temperature,
It exhibits a rubber-like property that returns to its original state when the force is removed, that is, superelasticity. Therefore, there is an advantage that appropriate rigidity is always given and the discomfort is reduced.

Further, the synthetic resin core material can be formed into a sheet-like shape in a free shape, is lighter than metal, and can have appropriate rigidity by adjusting the thickness. However, the usual synthetic resin core material has a drawback that it is deformed when a strong force is applied when it is worn or washed, and its shape is destroyed.

Further, the core material made of paper is light and can impart appropriate rigidity, but it has a drawback that it is broken by washing and has poor durability.

By the way, a wire rod made of metal or the like is not suitable for forming a wide shape over a wide area. Therefore, as shown in FIG. 5, in order to keep the shape wide and prevent the shape from being lost,
An elongated plate-shaped core material 41 having a certain width is used. Then, as shown in FIG. 6, the core member 41 is vertically arranged on the waist portion of the girdle 51, and attached,
I try to arrange the body line.

"Problems to be solved by the invention" However, even if a core material made of any material such as metal, synthetic resin, and paper is used as a plate-like core material having a certain width, the following problems There is.

In other words, the plate-shaped core material is difficult to bend three-dimensionally, and it is difficult to cope with the extremely complicated expansion and contraction required for fabrics such as girdles. I can't get a feeling.

In addition, since the plate-shaped core material has no air permeability or is poor in air permeability, the portion in which the core material is arranged is easily peeled off, and sweat or the like cannot be emitted.

By the way, Japanese Patent Publication No. 1-37481 proposes a core material in which a shape memory alloy is made into a fibrous wire rod, and the fibrous wire rod is knitted into a cloth and subjected to a memory treatment in a predetermined shape.

However, the core material has a risk of the shape memory alloy fibers piercing the skin and is easily bent three-dimensionally, but since it is made of metal fibers, it is difficult to cope with expansion and contraction, and the fit feeling is sufficient. Cannot be obtained in
Since it is a metal, it has a heavy weight, and there is a problem that a light wearing feeling cannot be obtained.

Therefore, the purpose of the present invention is to be able to arrange a wide range of shapes over a wide area, and to cope with extremely complicated stretching and shrinking of fabrics such as underwear. An object of the present invention is to provide a core material for clothes that is obtained and has excellent breathability.

[Means for Solving the Problems] In order to achieve the above object, the garment core material of the present invention comprises a shape memory resin having a glass transition point of body temperature or higher, welded or integrated at intersections, and having a pore diameter of 0.2 to. With a mesh that is 2 mm,
It is characterized in that it is composed of a cloth welded to the front and back surfaces of the mesh so as to sandwich it.

In the present invention, as the mesh, a shape memory resin wire rod arranged in a mesh shape and welded, or a shape memory resin sheet punched in a mesh shape is preferably used.

"Operation" In the present invention, the shape memory resin is a resin that positively utilizes the characteristic change at temperatures above and below the glass transition point peculiar to the polymer material. Temperature below glass transition point (glass area)
Has high rigidity, but at a temperature above the glass transition point (rubber region), the rigidity decreases and the material becomes rubber-like. When the rubber region is deformed to a desired shape and then cooled to the glass region as it is, the deformed shape is maintained and solidified. When this is heated to the rubber region again, it has the property of returning to the original shape memorized at the time of molding.

Since the core material for clothes of the present invention is composed of the mesh of shape memory resin, the following many advantages can be obtained.

The desired size and shape can be freely created, and the shape can be widely adjusted. The shape may be a simple plate, but may be formed into a three-dimensional shape such as a cup shape when used for a brassiere.

Even if the shape collapses during wearing or washing, the shape can be restored and restored by heating to the rubber region of the shape memory resin.

The weight is much lighter than that of a metal plate, a wire rod, or a cloth made by knitting a wire rod, and the present invention can also be applied to underwear or the like for which a light wearing feeling is desired.

Even if it is a wide plate, it can easily bend three-dimensionally, so it can cope with extremely complicated stretch and shrinkage of fabrics such as underwear, and a snug fit according to the movement of the body can be obtained.

Since it consists of a mesh with many holes, it has excellent breathability and can wick sweat and the like.

Like a metal mesh, there is less risk of the wire sticking into the skin, and it can be used safely.

By using a shape memory resin whose glass transition temperature is higher than body temperature, it becomes a glass region when worn, so rigidity is increased,
The shape retention force can be increased. When the shape is lost, the shape can be restored by heating the rubber region as described above.

It is easy to form into a mesh shape and a desired shape. For forming into a mesh shape, a method of arranging and welding a shape memory resin wire rod in a mesh shape, punching a shape memory resin sheet into a mesh shape, or the like is adopted.

Since the mesh is used, it is possible to sew it on when it is attached to clothes, and it is easy to attach it to clothes.

"Embodiment" FIGS. 1 to 3 show an embodiment of a garment core material according to the present invention.

The clothing core material 21 includes a shape memory resin mesh 12 and a cloth.
It is formed by sandwiching 13 and 13 and welding.

Various resins, such as manufactured products) are known, and any of these may be used.

As described above, the shape-memory resin mesh 12 is formed by arranging and welding the shape-memory resin wire rods in a mesh shape, punching a shape-memory resin sheet into a mesh shape, or the like, and welding or welding the mesh intersection points. Integrate.

The wire diameter of the shape-memory resin wire material constituting the mesh 12 may be appropriately set according to the intended use, but is usually 0.1.
It is preferably about 1 mm. The pore size of the mesh 12 is 0.2
~ 2mm

In this embodiment, the mesh 12 is composed of a flat sheet, but as described above, it has a three-dimensionally curved shape (for example, a cup shape when used for a brassiere) according to the shape of the body. Good. Such a shape can be formed by pressing the mesh 12 against a mold, heating it to near the pour point of the shape memory resin, and cooling it to the glass region while maintaining the shape.

The cloth 13 can be selected according to the intended use,
For example, a cloth made of cotton, nylon fiber, polyester fiber or the like is used, and particularly when used for undergarments such as a girdle, a stretchable cloth is preferable.

The method of welding the shape memory resin mesh 12 to the cloths 13 and 13 is as follows.
A method of welding itself (see FIG. 2), a method of spraying a melt material 14 such as nylon or polyethylene around the mesh 12 of the shape memory resin between the cloths 13, 13 and applying pressure (third method)
(See the figure) and the like can be preferably adopted. However, in the method of using the melt material 14, the amount of the melt material 14 used is adjusted, and after the melt material 14 is welded by heating and pressurization, voids are formed.
It is preferable that a large number of 15, 15 ... Are formed to maintain air permeability.

FIG. 4 shows an example in which the clothing core material 21 of the present invention is used in the waist portion of the girdle 31.

That is, the clothing core material 21 is widely attached to the waist portion of the girdle 31 and fixed by means such as adhesion. The clothing core material 21 has a wide sheet shape, but since the mesh 12 is used, it can be bent three-dimensionally and can be shaped to fit the delicate curved surface of the waist portion.

This girdle 31 has a soft shape-retaining force on the waist part, which can beautifully adjust the waistline.
In addition, since the shape memory resin mesh 12 bends and twists in any direction, it is possible to cope with extremely complicated stretching and shrinking of the fabric, and a light wearing feeling that fits perfectly to the body is obtained. To be

[Advantage of Invention] As described above, the core material for clothes of the present invention is formed by sandwiching the shape memory resin mesh with the cloth and welding it. Therefore, the cloth having a desired width can be used. It can be pressed to enhance the shape retention effect, and it can respond to complicated stretch and shrinkage of the fabric, giving a snug fit and a soft wearing feeling.
