Description

[Detailed description of the invention] The present invention relates to a method for manufacturing a wetsuit.

In particular, the present invention relates to a method for manufacturing a wetsuit that uses bellows-like rubber fabric in areas corresponding to joint flexion and extension areas of the body.

Conventionally, wetsuits have been reinforced by applying a sheet-like protective material to the parts corresponding to the joint flexion/extension parts, but these suits have a flat protective material applied on top of the wetsuit body. Because it was purchased twice, the elasticity was poor, causing problems with exercise. The following was considered as a protective fabric with superior elasticity and protection against external impacts.

■A protected area made by molding a sheet-like protected area body with a bellows-shaped front side using a synthetic rubber material, and thermally bonding jersey fabric to the front and back sides of the protected area body.

■Protection material made of synthetic rubber material, formed into a sheet-like protective material body with a bellows shape on the front side and a bellows shape on the back side, and thermally bonded jersey material to the front and back surfaces. .

Then, the wetsuit main body fabric and the protective fabric are sewn together by determining the position of these protective fabrics so that they correspond to the joint bending/extending parts of the body, and so that they can be expanded and contracted most effectively according to the bending/extending movement of the body. A wetsuit made of these materials was proposed.

Wetsuits with cholera-shaped protective areas have many advantages over wetsuits with flat protective areas, such as superior stretchability due to their elasticity, and a cushioning function against external impacts. However, on the other hand, there were problems in the process of creating the bellows-shaped protected land itself.

In other words, the protected real rhinoceros is made by melting the rubber material by heating.
It is made into a fluid state, poured into a mold, solidified by cooling,
Injection molding or foam molding, in which the rubber material is made into a liquid state, violently stirred, foamed, put into a mold, cooled and solidified, and then molded, requires a molding machine and mold for injection molding or foam molding. In particular, the cost required for the mold is expensive. In addition, it takes time and effort to install the mold and adjust its operation, and the cost becomes extremely high unless a certain amount of large-scale production is carried out.

There is a processing limitation in that the dimensions of the protected area main body obtained from one mold are constant, and it is not possible to correspond to the bending/extending parts of each joint of wetsuits of various sizes. In order to obtain protected land books of different dimensions, separate molds are required, resulting in problems such as an enormous increase in equipment costs.

The present invention was made in view of operational considerations, and its gist is to pressure-vulcanize a flat fabric made of synthetic rubber such as chloroprene sponge rubber into a bellows shape, and to create a bellows-shaped protection area body. This is a manufacturing method for a wetsuit obtained by sewing the protective fabric main body to correspond to the joint bending and stretching parts of the body, and its purpose is: - No need for expensive molding machines or molds. . Therefore, it is an object of the present invention to provide a method for manufacturing a wetsuit which has advantages such as reducing manufacturing costs, and (2) having no restrictions on dimensions and freedom in processing.

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In Fig. 1, numeral 1 denotes a flat fabric made of chloroprene sponge rubber (hereinafter referred to as flat fabric 1). The flat fabric l is made by sufficiently softening the raw rubber, adding a vulcanizing agent such as sulfur, and adding vulcanization accelerators, vulcanization aids, and various compounded chemicals, kneading it, and shaping it into a flat body. The temperature is raised to cause the sulfur and rubber to react, creating knots, or so-called crosslinks, in the rubber molecules at various points, creating a rubber-like elastic body. It is then produced by rapid cooling or cooling, and can be obtained arbitrarily from rubber manufacturers.

Such an arbitrarily available flat fabric l is fed into a predetermined position of a press heat plate 8is made up of an upper die 3 and a lower die 4 whose pressing surfaces are formed in a bellows shape 2, and the press heat plate 5 is heated for a predetermined time. By pressure heating, the rubber is softened and has elasticity, and is molded into a bellows-like shape suitable for pressing, and even after cooling, it exhibits rubber elasticity and maintains its shape. In other words, the protected area main body A can be formed by pressure vulcanization.

Fig. 2 shows that a flat fabric l is fed into a press hot plate 8 consisting of an upper die 6 whose pressing surface is formed into a bellows shape 2 and a flat lower die 7, and is pressure vulcanized in the same manner. The process of molding the main body B is shown.

As shown in Figs. 1 and 2, the present invention does not mold the protected area body by injection molding or foam molding, but by vulcanizing it under pressure with a press hot plate, etc., which requires expensive molding machines. It does not require a mold, so it has the advantage of reducing manufacturing costs.

FIG. 8 shows a wetsuit in which the protective fabric body obtained by pressure vulcanization is sewn into the main body of the protective fabric, with sections B positioned so as to correspond to joint bending/extension areas such as shoulders, elbows, and knees.

The main body of the protection area can be formed by obtaining a flat fabric of the desired dimensions and performing continuous pressing, so it can be shaped into a shape such as shoulders,
It is possible to obtain protected land bodies of various sizes that can accommodate areas such as elbows and knees.

In other words, the molding method using a mold can only obtain the size of the mold, but the present invention is not limited to the size of the press hot plate, and by feeding the flat dough and performing pressing operations continuously, the desired shape can be obtained. There is freedom in processing as the size can be obtained.

Therefore, in the operation example, the storage area body A1B was shown to be simply made of rubber, but it is also possible to use one made of rubber with jersey fabric thermally bonded to the front and back sides. be.

In order to solve this problem, the present invention applies pressure and vulcanization to a flat fabric made of synthetic rubber such as chlorosponge rubber into a bellows shape, obtains a bellows-shaped protection body, and makes the protection body correspond to the joint bending and stretching parts of the body. Since the manufacturing method of wetsuits is obtained by sewing wetsuits, ■ there is no need to use expensive molding machines and molds, so manufacturing costs are low; and ■ there are no restrictions on the dimensions of the molded product, making it easy to process We can provide a manufacturing method for wetsuits with the above freedom.

Representative Director Daito Takigawa 4 Agent 243-02 6 Specification subject to amendment All civilizations, vertical writing 1, title of invention '? ,, Ic upper n 1 stone de F 2 manufacturing method 2, Claims A flat fabric made of synthetic rubber such as chloroprene sponge rubber is pressure vulcanized into a bellows shape to obtain a bellows shaped retaining SM body. The main body of the protective material is applied to the joints of the body, particularly the parts of the body that correspond to the joint bending/extending parts. Conventionally, wetsuits have been known in which a sheet-like retaining material is applied to the parts corresponding to the joint bending/extending parts of the body to provide reinforcement. However, these 2-Ts have a flat protective area on top of the wetsuit body.
Due to its structure, it had poor elasticity, which hindered movement. For this reason, the following materials were considered as a material that has excellent elasticity and has a protective function against external shocks. A sheet-like material with a bellows-shaped front surface made of synthetic rubber material. A protection ground made by bonding j% jersey salt to the front and back sides of the main protection ground. ■Protection material made of synthetic rubber material, formed into a sheet-like protection material with a bellows-like shape on the front side and a bellows-like shape on the back side, and thermally bonded jersey salt to the front and back surfaces. . Then, the wetsuit main body fabric and the protective fabric are sewn together by determining the position of these protective fabrics so that they correspond to the joint bending/extending parts of the body, and so that they can be expanded and contracted most effectively according to the bending/extending movement of the body. A wetsuit made of these materials was proposed. Wetsuits with bellows-shaped protective areas have many advantages over wetsuits with flat protective areas, such as superior stretchability due to their elasticity, and a cushioning function against external impacts. However, on the other hand, there were problems in the process of creating the bellows-shaped protected land itself. In other words, the reserve is made by melting the rubber material by heating.
It is made into a fluid state, poured into a mold, solidified by cooling,
Molding machines and molds for injection R2 type or foam molding are used to obtain molding by injection molding, or by foam molding, which involves turning the rubber material into a liquid state, stirring it vigorously, foaming it, putting it in a mold, cooling it, solidifying it, and molding it. However, the cost required for the mold is expensive. In addition, it takes time and effort to install the mold and adjust its operation, and the cost becomes extremely high unless a certain level of large-scale production is carried out. Furthermore, there is a processing limitation in that the dimensions of the protective fabric main body obtained from one mold are constant, and it is not possible to accommodate the bending and stretching parts of each joint of wetsuits of various sizes. In order to obtain protected land bodies with different dimensions, separate molds are required, resulting in problems such as an enormous increase in equipment costs. The real deal! 91 was created from the viewpoint of operation, and its gist is that a flat cloth made of synthetic rubber such as chloroprene sponge rubber is sulfurized under 1111 pressure in the shape of a shirt.
The purpose of this method is to obtain a bellows-shaped protective area.■ Expensive molding machines and molds are not required. Therefore, it is an object of the present invention to provide a method for manufacturing a wetsuit which has advantages such as being able to reduce manufacturing costs, not being restricted to zero dimensions, and having freedom in processing. In Figure 1, 1 is a flat fabric made of chloroprene sponge rubber (hereinafter referred to as flat fabric 1). The flat fabric is made by thoroughly roughening raw rubber, adding a vulcanizing agent such as sulfur, kneading it with a vulcanization accelerator, a vulcanization aid, and various other chemicals, and forming it into a flat body. Then, the temperature is raised to cause the sulfur and rubber to react, creating knots, or so-called crosslinks, in the rubber molecules at various points, creating a rubber-like elastic body. It is then produced by rapid cooling or cooling, and can be obtained arbitrarily from rubber manufacturers. Such a flat fabric l, which can be made arbitrarily by hand, is fed into a predetermined position of a press hot plate 5 consisting of an upper die 3 and a lower die 4 whose pressing surfaces are formed in a bellows shape 2, and the press M plate 5 is pressed for a predetermined time. By applying pressure and heat, the rubber softens and has a riverbed property, and is molded into the shape of the bellows-shaped pressing surface, and even when it is later cooled, it exhibits rubber elasticity and retains its nozzle-like shape. In other words, the protected land main body A can be formed by IJD pressure vulcanization. Fig. 2 shows that a flat fabric l is fed into a press hot plate 8 consisting of an upper die 6 whose pressing surface is formed into a bellows shape 2 and a flat lower die 7, and is pressure vulcanized in the same manner. The process of molding this plcB is shown. As shown in Figures 1 and 2, the present invention does not mold the protected area body by injection molding or foam molding, but by press-vulcanizing it with a press hot plate, etc., which requires expensive molding machines and tools. It does not require a mold and therefore has the advantage of reducing manufacturing costs. FIG. 3 shows a wet suit in which the protected material body B obtained by pressure vulcanization is positioned and sewn to correspond to joint bending/extension areas such as shoulders, elbows, and knees. The main body of the protected area is made by obtaining a flat fabric with the desired dimensions and performing continuous pressing, so the shoulders, shoulders,
It is possible to obtain protective ground bodies of various sizes that can accommodate various parts of the elbows, knees, etc. In other words, the molding method using a mold can only obtain the size of the mold, but the present invention is not limited by the size of the press hot plate, and by feeding the flat dough and performing pressing operations continuously, the desired shape can be obtained. When the size is obtained there is freedom over the galoe. In the above example, the protected area main body A1B was shown to be simply made of rubber, but it may also be made of rubber with jersey fabric thermally bonded to the front and back sides. . In this way, the present invention involves pressure-vulcanizing a flat fabric made of synthetic rubber such as Rossbond rubber into a bellows shape, obtaining a bellows-shaped protective material body, and using an expensive molding machine and mold for the protective material. Because there is no need to do so, manufacturing costs are low, and
(It is possible to provide a manufacturing method for a square suit with no restrictions on the dimensions of the molded product and freedom in processing. 4.
