Abstract

PURPOSE:To hold a sealing medium, to which sublimation ink is applied, in a state of closely adhering to a tubular body to which patterns are to be set in a pattering method by a thermal transfer seal with sublimation ink. CONSTITUTION:A ground color 2 is applied to an outer peripheral face of a tubular body 1, or clear lacquer 3 is applied to the ground color, and then dried. The outer surface of the tubular body 1 thus processed is covered with a transfer medium 4 having a pattern formed on a heat-shrinkable film 4a by sublimation ink 4b. Thereafter, the transfer medium is heated and brought into close contact with the outer surface of the tubular body, and the pattern of the transfer medium is transferred to the tubular body.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for patterning a tubular body such as a fishing rod and a golf shaft, and more particularly to an improvement in a method for transferring a pattern to a tubular body by a sublimation ink heat transfer seal.

[0002]

2. Description of the Related Art A body color that is a ground color is applied to the outer peripheral surface of a tubular body such as a fishing rod formed by using a prepreg in which high strength and high elasticity fiber is impregnated with a synthetic resin, and a sublimation ink heat transfer seal is applied thereon. It is performed that the pattern of the seal is attached to the color of the main body by pasting and applying heat.

[0003]

By the way, when the sublimation ink thermal transfer seal used for patterning is heated, the ink applied to the seal changes from solid to gas (sublimation phenomenon), and the sublimation ink thermal transfer occurs. It has the property of penetrating into the paint of the base to which the seal is applied. The sublimation phenomenon described above is generally performed by applying heat at about 150 ° C. for about 15 minutes.Aluminum foil is used for the sublimation ink so that the base sealing material does not sublime. ing.

Certainly, the aluminum foil can sufficiently withstand heat enough to cause a sublimation phenomenon, but it is difficult to attach the aluminum foil to the tubular body to which a pattern is to be attached by closely attaching it. Have. Therefore, when wrapped around the tubular body, the heat transfer seal is partly separated (floating) from the surface of the tubular body, and as a result, the distance between the surface of the tubular body and the heat transfer seal varies and the tubular body There is a problem that the pattern transferred and formed on is blurred.

The present invention has been made in view of the above-mentioned problems of the prior art, and the purpose thereof is to:
The sublimation ink heat transfer seal is brought into close contact with the tubular body to be patterned so that clear patterning can be performed.

[0006]

In order to achieve the above object, the patterning method of the present invention is based on the background color or background on the outer peripheral surface of a tubular body formed by winding a prepreg of high strength and high elasticity fiber. A transparent clear is applied on the color and dried, and the outer surface is covered with a transfer material having a pattern formed by sublimation ink on a heat-shrinkable film, and then heated to bring the transfer material into close contact with the outer surface of the tubular body. The pattern of the transfer material is transferred to a tubular body.

A urethane resin type or a fluorine resin type is used as a transparent clear which is applied and dried on the main body color applied to the outer peripheral surface of the tubular body. The temperature of heating after applying the sublimation ink heat transfer seal is around 130 ° C.

[0008]

According to the above-mentioned means, since the transfer material coated with the sublimation ink used for patterning is a heat-shrinkable film, when the transfer material is applied to the tubular body and heated, the transfer material is applied. Shrinks and adheres to the outer peripheral surface of the tubular body, and the transfer material is not separated from the surface of the tubular body and does not float up, whereby the pattern transferred to the tubular body side is clearly visible.

[0009]

EXAMPLE An example of the present invention will be described below with reference to the drawings. FIG. 1 shows the steps of the method according to the present invention. A prepreg obtained by impregnating high-strength and high-elasticity fiber with synthetic resin is wound around a mandrel. A body color 2, which is a ground color, is applied and dried on the outer peripheral surface of a tubular body 1 formed by a conventional method, and a urethane resin-based or fluororesin-based transparent clear 3 is further applied and dried on it. (See Figure 1 (a))

On the outer periphery of the tubular body 1 constructed as described above, the transfer material 4 having a pattern formed on the heat-shrinkable film 4a by the sublimation ink 4b is covered so that the pattern surface faces the surface of the tubular body (FIG. 1 (b ) And (c)), and then transfer material 4 to 130
When heat of about ℃ is applied, the transfer material instantly shrinks and adheres to the outer peripheral surface of the tubular body 1 (see FIGS. 1 (d) and (e)), and the heating is continued for about 20 minutes. The sublimation ink 4b of the transfer material 4 penetrates into the layer of the main body color 2 or the transparent clear 3 applied to the tubular body 1 to complete the transfer. (See Figure 1 (f))

That is, the heat-shrinkable film by the above heating
Sublimation ink 4b adhered to 4a is in the main body color 2 applied and formed on the tubular body 1 by the sublimation phenomenon, or in the transparent clear 3 when the transparent clear 3 is laminated on the main body color 2. It permeates, solidifies in the permeation layer, and the pattern formed on the transfer material 4 by coating is clearly transferred without blurring. When the transparent clear 3 is laminated on the main body color 2, the sublimation ink 4b is held in the transparent clear 3 and does not mix with the main body color.
The original color is revealed as it is.

[0012]

As described above in detail, the patterning method according to the present invention has a background color or a transparent clear layer on the background color of the outer peripheral surface of a tubular body formed by winding a prepreg of high strength and high elasticity fiber. After coating and drying, the outer surface of the transfer material is covered with a transfer material having a pattern formed by sublimation ink on a heat-shrinkable film, and then heated to bring the transfer material into close contact with the outer surface of the tubular body, and to transfer the pattern of the transfer material. Since it is designed to be transferred to the tubular body, the transfer material adheres to the outer peripheral surface of the tubular body,
There will be no separation. Therefore, the transfer material is transferred uniformly over the entire pattern, the pattern is transferred clearly, and the blurring of the pattern that has occurred in the case of the sublimation ink thermal transfer sheet of aluminum foil can be reliably eliminated. Therefore, it is possible to provide a patterning method capable of increasing the commercial value by revealing a clear pattern.
