Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible and stretchable elastic sheet, a protective suit for exercise and an accessory for exercise using the same, and more particularly to a flexible and elastic suit such as a wet suit or a dry suit. A stretchable elastic sheet material suitable as a material for exercise protective clothing formed using a stretchable elastic sheet body and related accessories for exercise such as gloves, pads or supporters as related products, and Sports protective clothing and sports accessories.

[0002]

2. Description of the Related Art Chloroprene rubber and other foaming materials are used as protective clothing for sports such as wet suits and dry suits, and for sports accessories such as gloves, pads or supporters as related products. A knitted fabric with a stretchable and flexible elastic sheet body made of rubber or the like as a base material, and on one or both sides thereof appropriately colored, such as a jersey, which can be stretched in the vertical and horizontal directions, or
By sticking a knitted fabric that can be stretched in the vertical and horizontal directions with a high degree of elongation and can be made without pile, the substrate is hardly attached and detached by being rubbed so as to be directly in contact with the skin and caught, and There has been known one which eliminates a decrease in strength due to abrasion of the surface and enhances heat retention and decorativeness.

[0003]

However, when a knitted fabric such as a jersey or a knitted fabric that can be made into a pile is adhered to one or both surfaces of an elastic sheet body used as a base material, the elastic base material must be used. In addition to reducing the frictional resistance between the skin and the skin, it becomes easy to attach the protective clothing for exercise and exercise accessories, and the surface of the base material is protected so as not to be exposed, and the decrease in strength is suppressed. The thickness of the article formed by using the base material is increased, and since it becomes possible to apply a free color, the heat retaining property and the decorative property are enhanced, but the product is attached to the surface of the base material. Each of the above knitted fabrics has a limit in the degree of elongation as compared to the base material made of an elastic sheet body, no matter how stretchable, but rather hinders the stretchability of the base material itself and makes it difficult to move. The disadvantage of this is that it is not.

[0004] That is, knitted fabrics such as jerseys and knitted fabrics that can be made without pile are rich in elasticity in the vertical and horizontal directions, but in any case, knitted fibers (yarns) having a limit in the degree of stretching. Since it is a fabric, it cannot be denied that the degree of elongation is inferior to that of the base material made of the elastic sheet body. Since the drag (shrinkage force) against the stretching of the base material exceeds the extensibility of the base material and suppresses the expansion, it gives a cramped feeling that the base material itself has difficulty in moving when mounted. It is not possible to make full use of the nature. And such a defect is remarkable when the knitted fabric is stuck on both surfaces of the base material.

[0005] Knitted fabrics such as jerseys also have the drawback that water drains poorly, absorbs a large amount of water and becomes heavy, and the absorbed water deprives the body temperature and lowers the heat retention. Things.

[0006]

In order to solve the above-mentioned problems, the present inventors have made intensive studies and as a result, they have adhered unwoven fibers to the surface of a base material made of an elastic sheet body. Integral with the material, the elastic flocked sheet material without compromising the original elasticity of the base material made of the elastic sheet body, and using this, protective clothing for exercise and accessories for exercise By forming, the surface of the elastic sheet body as the base material is covered with the fiber so that the frictional resistance with the skin is reduced, the heat retention is enhanced, and further, the bonding of the unwoven fiber is performed. In this case, the decorativeness can be enhanced by giving the fiber a desired color or giving the fiber an arbitrary color.

[0007] That is, the present invention provides at least one surface of a flexible and stretchable elastic sheet body,
It is a stretched flocking sheet material obtained by sticking short fibers in an upright state, whereby the elastic sheet body as a base material and the short fibers which are non-woven fibers stuck to the surface thereof are The short fibers are joined only at one end in the longitudinal direction of the short fibers to be integrated, and even when the base material is stretched, the short fibers themselves are stretched along with this, and the stretching of the base material is performed. Since it is not suppressed, there is no influence on the elasticity of the substrate itself.

[0008] Here, the staple fiber referred to in the present invention is a powdered fiber having a length capable of standing up by electrostatic phenomena, specifically, a powdery fiber having a length of about 2 mm or less or close to the powder. It is intended to refer to so-called "flock" fiber waste. Thus, the so-called electrostatic flocking means causes the short fibers to be vertically adhered to the surface of the elastic sheet body, which is the base material to which the adhesive has been applied, as if flocking. In addition, the thickness of the elastic sheet body in which the short fibers are stood upright and stuck vertically is particularly limited because it can be appropriately selected according to the target exercise protective clothing and exercise accessories. However, in consideration of the easiness of stretching of the elastic sheet body accompanying the movement, it is roughly 1 to 1
The thickness is preferably about 6 mm.

The present invention also relates to a method of adhering a knitted fabric such as a jersey which can be stretched in the vertical and horizontal directions or a knitted fabric which can be made into a pile on the other upper surface of the elastic sheet body to which no short fibers are attached. It is a stretchable flocking sheet material made by this, by attaching fibers to the front and back surfaces of the base material, thereby increasing the thickness of the flocking sheet material and enhancing the heat retention, Decorative properties will be enhanced by the texture of the knitted fabric such as the attached jersey and any color applied to the knitted fabric, and even if fibers are attached to both the front and back surfaces of the base material, Since only one of the fibers is on one side, the elongation is not significantly suppressed.

[0010] The present invention also provides a stretchable flocking sheet material obtained by applying a slippery resin such as polyurethane to the other upper surface of the elastic sheet body on which short fibers are not adhered. Thus, the knitted fabric or the like is not stuck on the other upper surface, so that its extension is not significantly suppressed, and the surface of the base material is coated with the slippery resin. Therefore, even if the other surface is in direct contact with the skin, the substrate and the skin are easily slid without being rubbed.

[0011] The present invention also relates to any of the above-mentioned stretchable flocking sheet material, that is, a flocking flocking sheet material obtained by sticking short fibers in an upright state on one surface of a soft and stretchable base material. Or, the flocking sheet material in which the short fibers are stuck on both front and back surfaces of the base material in an upright state, and the short fibers are stuck on one surface of the base material in an upright state, and on the other surface. A flocked sheet material obtained by sticking a knitted fabric such as a jersey or the like which can be stretched in the vertical and horizontal directions or a knitted fabric which can be made into a pile, or a short fiber is stuck on one of the surfaces of the base material in an upright state. In addition, the protective clothing for exercise or the accessory for exercise is formed by using a flocking sheet material obtained by applying a slippery resin such as polyurethane on the other surface.

[0012] Then, when forming the exercise protective clothing,
The whole may be constituted by using the above-mentioned elastic flocking sheet material. However, for example, at least the elbow, knee, waist (back), buttocks (thigh) The elastic flocked sheet material may be arranged only on the back), underarms and the like. Accordingly, even if the elastic flocked sheet material is partially disposed, the bending and stretching operation is not suppressed as in the case where the entirety is constituted by the elastic flocked sheet material.

The exercise protective clothing intended in the present invention includes diving, surfing, windsurfing, water skiing, body boarding, fishing, and various sports (leisure) underwater or on the water, and rescue of human lives ( It is possible to use clothes called so-called wet suits or dry suits that are used in lifesaver, camera photography, collection of seaweed, shellfish, and the like, and other operations underwater and on water.

When the exercise accessory is formed, it is preferable to partially cover a portion to be extended in exercise, for example, a finger, an elbow or a knee. Thereby, the bending and stretching operation in the movement is not suppressed, and the portion to be extended is protected from impact, friction, and the like. As the exercise accessories, gloves, hoods, pads, supporters, and the like as related items in the exercise protective clothing can be considered.
