Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof garment, for example, a dry suit worn by a diver or a kappa worn by a fisherman or the like, and more particularly to a waterproof garment having an improved wrist, ankle, or a portion where the neck is inserted. It is a thing.

[0002]

2. Description of the Related Art Waterproof garments are designed to keep water out. However, it is worn by humans, and it is almost impossible to completely waterproof it. The main places of inundation are the neck portion, wrist portion, and ankle portion of the waterproof garment (in this specification, these portions are collectively referred to as "seal portion").

In the dry suit, in order to enhance the waterproof property of the seal portion, a ring body of latex rubber or neoprene rubber is conventionally attached to this portion. Latex rubber is a thin, highly elastic rubber that is more waterproof than neoprene rubber. However, since the tightening force is also strong, it is required to have an appropriate size. Therefore, manufacturers often make a slightly smaller seal part, and the diver often cuts the rubber according to his size after purchase.

This rubber ring body is molded separately from the dry suit and is bonded to the tip of the seal portion of the dry suit with an adhesive. However, this rubber ring body and the waterproofed PVC, which is the surface material of the dry suit body, have poor adhesion and cannot be easily adhered as they are. Therefore,
These rubber ring bodies are pre-treated with sandpaper to make them uneven so that the adhesiveness is improved, and then the both are bonded with an adhesive.

[0005]

Needless to say, such pretreatment is time-consuming and labor-intensive and increases the manufacturing cost of the dry suit. It is an object of the present invention to provide a waterproof garment with an improved seal portion to eliminate the need. The invention further provides a method of making such a seal.

[0006]

A waterproof garment according to the present invention comprises a waterproof garment main body and a rubber seal part connected to the neck, wrist and ankles of the main body, and a seal part of the part to which both are connected. Is characterized in that at least a part thereof is lined with a base fabric.

The waterproof garment is, for example, a dry suit or kappa. The main body itself may have any structure as long as it has a waterproof function and a seal portion.

In the case of dry suit, the rubber of the seal part is
Currently, as mentioned above, latex rubber is normally used, but other rubbers may be used. The shape of the seal portion is usually in two steps, that is, a substantially uniform wide ring portion and a tapered tip ring portion.

A feature of the present invention is that a base cloth is attached to the inside of the seal portion. The base cloth is attached to the substantially uniform wide ring portion, and the tapered tip ring portion is left as rubber. As the material for the base cloth, for example, a woven fabric, a knitted fabric, or a woven fabric or a knitted fabric whose one surface is coated with a resin is used. The resin to be coated is, for example, P
VC, polyurethane, natural / synthetic rubber, EVA, etc.

The method of adhering the base cloth to the rubber of the seal portion includes a step of winding the base cloth around the rubber seal portion forming die,
The process comprises the steps of immersing the mold on which the base cloth is wrapped in a rubber solution, vulcanizing, chlorinating, removing the rubber seal part with the base cloth from the mold, and drying. Before and after the step of removing the seal portion from the mold, a water washing step may be added to remove foreign matter from the rubber surface. Vulcanization is performed at a temperature of 140 ° C. for 30 to 120 minutes, for example. Chlorine treatment is performed to prevent discoloration of the product and to make the surface slippery.

[0011]

According to the present invention, at the portion where the waterproof garment main body and the rubber seal portion are connected, the seal portion is lined at least partially with the base cloth. The seal portion lined with the base cloth and the waterproof garment body can be easily sewn. Further, when a base cloth having one surface coated with a resin is used, the resins can be welded together.

[0012]

Embodiments of the present invention will now be described with reference to the accompanying drawings, taking a dry suit as an example. FIG. 1 shows a part of a main body 1 of a dry suit and a seal portion 2 of this waterproof garment.
3 is a cross-sectional view of the rubber body of FIG. The whole dry suit is not shown because the dry suit itself is well known and any one can be used. Although the seal portions for wrists, ankles, and necks are slightly different in size, they are structurally almost the same, and therefore they are represented in one drawing.

As the rubber of the seal portion 2, latex rubber is usually used. The shape of the seal portion 2 is in two steps, that is, a substantially uniform wide ring portion 3 and a tapered tip ring portion 4. In the case of a dry suit, the diver can cut the rubber of the tip ring portion 4 according to the size of his / her wrist, ankle, and neck so that the rubber can be brought into close contact with the body.

The base cloth 5 is lined only on the above-mentioned substantially uniform wide ring portion 3, and it is preferable that the tapered front end ring portion 4 is left as rubber. This is because rubber alone makes it easier to adhere to the body. The material of the base cloth 5 is, for example, a nylon 420d × 420d woven fabric. Other woven fabrics, knitted fabrics, and woven fabrics or knitted fabrics coated on one side with a resin such as PVC can also be used. As the resin to be coated, polyurethane, natural / synthetic rubber, EVA or the like can be used.

To attach the base cloth to the rubber of the seal portion 2, the base cloth is wrapped around a mold and immersed in a rubber solution, and then about 1
Vulcanize at a temperature of 50 ° C. for about 80 minutes. Then, after chlorine treatment, it is washed with water, the seal part is removed from the mold, and dried.

The seal portion 2 is connected to the waterproof garment body 1. In this embodiment, the seal part 2 is connected to the outside of the waterproof garment 1, but may be connected to the inside. The seal portion 2 lined with the base cloth and the waterproof garment body 1 can be easily sewn. Further, when a base cloth having one surface coated with a resin is used, the resins can be welded together.

[0017]

According to the present invention, at the portion where the waterproof garment main body and the rubber seal portion are connected, the seal portion is lined at least partially with the base cloth. As described above, the seal portion lined with the base cloth and the waterproof garment body can be easily sewn. Further, when a base cloth having one surface coated with a resin is used, the resins can be welded together. Therefore, the complicated pretreatment for the back surface of the rubber, which is required in the conventional technique, is no longer necessary.
