BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoulder pad and a brassiere for outerwear, a foundation such as a bodysuit, an innerwear, and a shape-retaining core material for clothing such as sports clothing.

[0002]

2. Description of the Related Art Various shape-retaining core materials are used for clothing depending on their use and function. The function required of these shape-retaining cores is that when the wearer moves his / her arm etc. and exercises, the external stress applied in response to the expansion / contraction of clothes due to the change in the shape of the body surface is removed. When restored, it quickly returns to its original shape with little permanent set.

Also, there are no sharp or rugged hard parts in the surroundings, and not only is the contact soft when worn,
It has an appropriate thickness and elasticity, the above-mentioned function does not deteriorate for a long period of time, and it is light and does not cause discomfort when worn.

A shoulder pad is a typical shape-retaining core material for clothing. Taking this as an example, the elasticity described above,
In addition to requirements such as resilience, flexibility and safety, moderate thickness and elasticity, light weight and no discomfort, there is a main purpose to prepare the body shape of clothes and body, so processing into a three-dimensional shape that conforms to the body shape There is a strong demand for ease of use.

As a method for realizing this three-dimensional processing, a urethane foam core material is cut out into a three-dimensional shape and the periphery is covered with a cloth to cancel the uncomfortable feeling, and a three-dimensional mold is inserted to fix the shape to a desired shape. Some of them are heated to be thermoplastically deformed, and some of them are stacked to form a three-dimensional shape by stacking non-woven fabrics and slightly shifting each layer and sewing.

[0006]

[Problems to be solved by the invention] A shoulder pad made by cutting a urethane foam block into a three-dimensional shape and a shoulder pad made by sandwiching and fixing thin urethane foam in a three-dimensional mold and heating it Since automatic machines can be used for a short time,
Although it is suitable for mass production and can be supplied at low cost, it has a problem that it cannot be used for high-grade outer garments because it has poor moisture permeability and its elasticity is too strong to adapt to the wearer's body shape.

In the case where the urethane foam is manufactured by pressing, the urethane sheet in the sheet state before pressing has a uniform thickness, and the thin portion in the periphery is the same material compressed further. Therefore, the area around the pad has a high density and is hardened, and the contact with the skin when worn is deteriorated.

In order to prevent this, even if urethane foam whose peripheral portion is thinly sliced is used, if the cut shape of the urethane foam material does not match the wearer's body shape,
It has a high elasticity and retains the shape at the time of manufacture, making it a core material with poor wear stability.

Further, the shoulder pad made by stacking the non-woven fabrics has a good moisture permeability and also has an appropriate elasticity in the thickness direction of the pad. It is used as a very good one because it fits into the body shape.

However, since the work for forming the three-dimensional shape is complicated and cannot be automated, the manual production is mainly performed.
Not only mass production is not possible, but skilled workers are required, cost is high and quality varies widely, and it is not always a product that can satisfy the garment manufacturer and customers.

The present invention has been researched and developed with the object of solving the above-mentioned problems, and is a three-dimensionally curved shape utilizing the difference in the heat shrinkage ratio of the non-woven fabric used, and has moisture permeability and elasticity. It is an object of the present invention to provide a shape-retaining core material for clothing, which is well adapted to the human body shape and can be mass-produced.

[0012]

Means for Solving the Problems As a means for solving the above problems and achieving the object, in the present invention, non-woven fabrics having different heat shrinkages are laminated and adhered and heat-shrinked to obtain a non-woven fabric having a large heat shrinkage. We have developed and adopted a shape-retaining core material that can be curved into a three-dimensional shape. Further, in the present invention, in the shape-retaining core material configured as described above, the non-woven fabric having a small heat shrinkage is thick,
We have developed and adopted a shape-retaining core material that is made of a thin non-woven fabric with a high heat shrinkage ratio.

[0016]

[Function] A three-dimensional shape is created by bending the core material by utilizing the difference in heat shrinkage, and a shape desired by the designer or designer is created by carrying out this heat treatment inside the three-dimensional mold. Therefore, the number of parts where the manufacturing process can be automated and mechanized is increased.

For example, nonwoven fabrics 1 and 2 having different heat shrinkage rates are cut in advance to a required width, the nonwoven fabrics 1 and 2 are bonded to each other to produce a strip-shaped core material 3, and upper and lower surfaces thereof are covered with a covering cloth 4. It is possible to manufacture it by picking it up and sewn around it by punching it and heat-treat it from the top and bottom with a die and heat-treating it as a unit. There is no need for a skilled person, and most steps can be mechanized.

As another method, the non-woven fabrics 1 and 2 having different heat shrinkage rates are cut in advance to a required width, and the non-woven fabrics 1 and 2 are cut.
To produce a strip-shaped core material 3, which is cut out into a thin disk-shaped periphery, and the upper and lower surfaces are sandwiched with a covering cloth and punched together with the dough. It can also be manufactured by sewing. In this case, the circumference of the finished pad is thinner than the central part, and it is less likely to affect the silhouette of the outer garment, and the hardness of the surroundings is closer to the central part.
