Description

Detailed Description of the Invention

[0001]

[0001]

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing an article having a multicolored printing part capable of accurately and easily forming a multicolored printing part having a complicated design on a swimming cap or the like.

[0003]

[0002]

[0004]

2. Description of the Related Art In recent years, swimming caps have been increasingly required not only for their original practical purpose such as sanitization in a pool but also for a preference factor of fit and fashion. This is a result of improvements in materials such as high stretchability, resulting in improved fitability.

[0005]

Materials for swimming caps include cloth and latex,
There are various kinds of rubber such as silicone rubber,
The market share and growth rate are different depending on the characteristics of each material, but for all swimming caps of any material, fashionability is improved by devising the color, luster, pattern, etc. of the swimming cap. Also, there is a tendency to increase added value by printing brand names and character marks.

[0006]

Conventionally, several printing methods can be selected on the swimming cap depending on the material. For example, rubber-based swimming caps are mainly printed directly on the swimming cap body by screen printing.

[0007]

[0005]

[0008]

However, the direct printing on the swimming cap by the conventional screen printing method is limited to the simple design, and the multicolor printing can only be the simple design. That is, multicolor printing with a complicated and accurate design such as color printing has many factors that deteriorate the production efficiency such as the thickness of the swimming cap body being highly elastic and the color misregistration due to the difficulty of alignment. However, there is a problem in terms of supply and cost, and it has not been offered to the general public, and it is the current situation that multicolor printing with a complicated and accurate design is not performed.

[0009]

The present invention has been made in order to improve the above-mentioned circumstances and has the same elasticity as an article to be subjected to multicolor printing, such as a swimming cap, and has a complicated and accurate structure without peeling or cracking. It is an object of the present invention to provide a method for manufacturing an article, which can easily form a multicolor printing portion of a design, and is advantageous in terms of production efficiency and cost, and which has improved fashionability and commercial value.

[0010]

[0007]

[0011]

In order to achieve the above-mentioned object, the present invention forms a multicolor printing portion of a silicone rubber type ink on a sheet having releasability, and then forms this multicolor printing portion. Multicolor printing characterized by covering and forming an uncured silicone rubber layer, press-bonding this silicone rubber layer to an article to be subjected to multicolor printing, curing, and then peeling off the sheet having releasability. A method of manufacturing an article having a part is provided.

[0012]

That is, multi-color printing is applied to a releasable sheet by screen printing or the like, and an uncured silicone rubber layer is formed on the sheet with a silicone rubber-based ink or the like, which is formed in advance. To the surface of a swimming cap, etc. by applying pressure to the surface of the same, heating it in some cases to cure the silicone rubber layer, and transferring only the multicolor printing part to the swimming cap etc. through this cured silicone rubber layer. It is possible to easily perform printing, in particular, multicolor printing having complexity and accuracy.

[0013]

The present invention will be described in more detail below. As the material of the releasable sheet on which the multicolor printing portion is first formed, it is sufficient that the material has releasability from the multicolor printing portion, and particularly, Although not limited, when a silicone rubber-based ink is printed and heat-cured for each color when forming a multicolor printing portion, a material having heat resistance and less heat shrinkage is preferably used. Specific examples include metals such as aluminum, copper, iron and stainless steel, and polymer resins such as fluororesin, silicone resin, polyimide resin, polypropylene and polyethylene terephthalate, and many of these can be used as they are. . In the case of a material having a poor releasability, it can be used in the same manner by coating the surface with a release-curing agent, for example, a surface-active agent or a fluorine-based or silicone-based release agent.

[0014]

As the silicone rubber-based ink for forming the above-mentioned multicolored printing portion, those having the same expansion / contraction ratio as the article to be subjected to the multicolored printing such as a swimming cap body are preferable, but regarding the silicone rubber-based ink, It is easy to produce colors and has good physical properties such as weather resistance and adhesiveness, and can be favorably used regardless of the material of the article.

[0015]

The silicone rubber ink includes an addition reaction curable type and a condensation reaction curable type, and both are preferably used. In this case, it is recommended to use the condensation reaction curing type from the viewpoint of adhesiveness and low temperature curing, and the addition reaction curing type from the viewpoint of workability such as adjustment of curing time.

[0016]

The multicolor printing portion can be formed on the releasable sheet by employing a known printing method such as a screen printing method. A silicone rubber ink is printed and cured for each color to obtain a multicolor printing portion. A method such as applying a color print design can be adopted. In this multicolor printing, the above-mentioned silicone rubber-based ink is printed on the release sheet in a reversed form of the design to be finally printed to complete the multicolor printing.

[0017]

Next, an uncured silicone rubber layer is formed so as to cover the thus formed multicolor printing portion. For example, silicone rubber ink can be used to form this silicone rubber layer. In this case, the silicone rubber layer may be transparent or may have the same color as an article to be subjected to multicolor printing, such as the body of a swimming cap, and when the article has low brightness, You can also make it white to increase the saturation.

[0018]

As described above, the release sheet on which the multicolor printing portion and the uncured silicone rubber layer are formed is placed on the side of the article to be multicolor printed such as the body of the swimming cap, the silicone rubber layer being arranged. With the silicone rubber layer in an uncured state, a release sheet is applied to a portion of the article to be printed, which is press-bonded using a pressing machine or the like to be cured. By removing air bubbles present between the main body and the ink by this pressure bonding,
The adhesive strength of printed matter can be increased. When the ink is a thermosetting type, a press machine capable of heating is used to cure and adhere by pressurizing and heating. In addition, the above-mentioned press does not have to be a special one, and it can be
A device for printing on a shirt or the like is also possible, and depending on the size, a household iron or the like can be substituted. Here, the material of the article such as the body of the swimming cap is not particularly limited, and may be rubber such as silicone rubber or cloth.

[0019]

Next, the release sheet is peeled off from the article, and only the multicolor printing layer and the uncured silicone rubber layer are left on the article. However, since the release sheet has releasability as described above, the peeling work is easy. Can be done Therefore, it is possible to perform printing more easily than the conventional multicolor printing.

[0020]

In addition to swimming caps, T-shirts, polo shirts, and the like are examples of articles to be subjected to multicolor printing.

[0021]

According to the multicolor printing method for articles of the present invention,
Printing on the releasable sheet is not limited to the screen printing method, the object of the present invention can be achieved by any printing method, and a screen possessed by a manufacturer who manufactures a swimming cap or the like and who is involved in the printing thereof can be used. The printing device such as a printing machine can be used as it is. Further, since the swimming cap body and the like are manufactured and then transfer printing is performed on the swimming cap body and the like, the manufacturing efficiency and cost are superior.

[0022]

Therefore, compared to the conventional multicolor printing, it is possible to perform printing easily, and since the printing is completed by the above printing process, the process of the main body and the printing can be divided, and the total cost can be reduced. Can also be reduced. In other words, since the printed release sheet can be stored, planned production can be performed. In addition to mass production, the pre-printed release sheet and multicolor printing should be performed. There is a merit that it is possible to respond to the order even if a small amount of a wide variety of products is manufactured by preparing the articles.

[0023]

[0019]

[0024]

According to the method for producing an article having a multicolor printing portion of the present invention, it is possible to easily carry out multicolor printing of a complicated and accurate design which does not cause peeling or cracking, which is advantageous in terms of cost. It can be manufactured.
