A method of producing a cloth label for a multicolored garment, characterized by selecting an order.

 Hereinafter, the method of the present invention will be described in more detail.

The recording medium for forming a pattern used in the method of the present invention is a so-called "thermal transfer recording medium" in which a thermal transfer layer is provided on a support.

The support of the thermal transfer recording medium is a plastic film having a thickness of about 3 to 10 μm, for example, a polyester film, a polycarbonate film, a polyimide film, a wholly aromatic polyamide film, a polyetheretherketone film, a polysulfone film and the like. .

The thermal transfer layer formed on the support is mainly composed of a colorant and a binder, and both the colorant and the binder are water and a solvent used for washing such as dry cleaning (chlorine-based solvent, fluorine-based solvent). Solvent, naphtha, etc.). Such a colorant is selected from carbon black, other inorganic pigments, and organic pigments. In general, in the first color pattern formation, a dark color (black, dark blue, brown, etc.) is used. Use of things is effective. As the binder, polyvinyl chloride, polyvinylidene chloride, fluororesin, polyvinyl butyral, polyester, polyamide, polyacrylonitrile, polyurethane and the like are used. The ratio of the colorant / binder in the thermal transfer layer was 50 by weight.
/ 50 to 99/1, preferably 70/30 to 90/10. When the proportion of the colorant is more than 99% by weight, the dispersion of the colorant in the binder becomes insufficient, and at the same time, the function as the binder also becomes insufficient, so that the thermal transfer layer (ink layer) is removed from the support.
Is easy to fall off. Conversely, if the proportion of the coloring agent is less than 50% by weight, it becomes difficult to obtain a clear pattern.

In order to improve the dispersibility of the colorant and prevent the thermal transfer layer from falling off the support, a surfactant or a wax may be added to the thermal transfer layer, if necessary. It is within a range that does not lower the cleaning property and the iron resistance.

The transfer object of the present invention is a cloth. As the cloth, a synthetic fiber such as acetate, nylon, polyester, acrylic or the like or a non-woven fabric thereof can be used.

By the way, as mentioned above, in the method of the present invention, a pattern (characters, symbols, figures, etc.) composed of two or more colors is provided on the transfer target. Therefore, for example, to obtain a two-color pattern, after the first pattern is formed on the transfer target, the second pattern having a different hue from the first pattern is formed by the first pattern.
It is formed at a necessary place on the pattern. Further, in order to form a three-color pattern on the transfer object, after the first and second patterns are formed, a third pattern having a hue different from those two colors is formed by the first and second patterns. It is formed in the necessary place above.

In the implementation of the method of the present invention, the second color is lighter than the first color, and the third color is lighter than the second color.
It is desirable that such consideration be given to the colorant of the ink layer to be patterned later. As the thermal transfer recording medium used in the method of the present invention, two or more monochromatic thermal transfer recording media may be prepared, but the first thermal transfer layer, the second thermal transfer layer... It is advantageous to provide them sequentially and add alignment marks as needed. To perform, for example, two-color recording using such a thermal transfer recording medium, the first pattern is formed on the thermal transfer recording medium, and then the thermal transfer recording medium is aligned so that the second pattern is formed by the marks. Later, thermal transfer recording method,
The second pattern may be formed by a hot stamp method or the like.

In the practice of the method of the present invention, as described above, the second thermal transfer recording medium is provided separately from the first thermal transfer recording medium, and if necessary, the third, fourth,. , And the first pattern is formed by the thermal transfer recording method, and then the second, third, fourth,... Patterns are formed on the pattern by the thermal transfer recording method and the hot stamp. Absent.

Further, in the practice of the method of the present invention, the recording medium for forming the second pattern is ink, and a conventionally known ink such as a printing ink, a hot melt ink, a liquid ink for a stamp is formed on the first pattern by a relief printing method. . However, it is needless to say that the various inks used here need to have cleaning resistance and iron resistance.

As described above, in the present invention, the first pattern is formed by superposing the thermal transfer layer surface of the thermal transfer recording medium and the receiving surface of the object to be transferred from the side opposite to the thermal transfer layer of the thermal transfer recording medium. The thermal transfer layer is transferred to the transfer target by applying thermal energy through the substrate. The second pattern formation may employ the same means as the first pattern formation, or may employ a means for pressing using a relief plate heated to about 100 to 200 ° C. instead of the thermal head. I don't care.

Next, examples and comparative examples will be described. Parts here are by weight.

Example 1 (Preparation of first ink layer forming liquid) A mixture composed of 10 parts of carbon black, 10 parts of nylon, and 80 parts of methanol was dispersed in a ball mill for 24 hours to prepare a first ink layer forming liquid.

(Preparation of Second Ink Layer Forming Liquid) A mixture comprising 10 parts of Lake C and 10 parts of nylon 12 and 80 parts of methanol was dispersed in a ball mill for 24 hours to prepare a second ink layer forming liquid.

These first and second ink layer forming liquids have a thickness of about 4.5 μm.
The first ink layer and the second ink layer each having a thickness of about 1 μm were formed by gravure printing on the polyester film in a sequential manner to form a thermal transfer recording medium.

Subsequently, using a thermal transfer printer (line type head, applied energy: 10 to 25 mj / mm ² ), printing was performed on a woven nylon fabric (manufactured by Dynic) to form a two-color pattern of black and red. Washing test (JISL-0844, JISL-08
When subjected to 60), no dropout of the image was observed.

Example 2 The first ink layer forming liquid and the second ink layer forming liquid of Example 1 were each coated on a polyester film having a thickness of about 4.5 μm using a wire bar and dried to form a thermal transfer layer having a thickness of about 1 μm. Then, a first thermal transfer recording medium and a second thermal transfer recording medium were prepared.

Subsequently, the first pattern was formed on the nylon-processed woven fabric by the thermal transfer printer of Example 1 using the first thermal transfer recording medium. Next, the thermal transfer layer of the second thermal transfer recording medium is overlaid on the first pattern, and the copper relief plate heated to 150 ° C.
Pressing for 2 seconds formed a second pattern.

Example 3 The second pattern was relief-printed on the first pattern formed in Example 2 with a commercially available red ink for relief printing.

Comparative Example 1 A two-color pattern was formed in the same manner as in Example 2, except that the first pattern was formed by pressing a copper relief plate heated to 150 ° C. for 1 second.

Comparative Example 2 A two-color pattern was prepared in the same manner as in Example 3, except that the second pattern was formed by letterpress printing using a commercially available letterpress black ink.

The evaluation of the label produced as described above was as follows.

[Effect of the Invention] The first pattern is thermal transfer recording by a thermal head,
By directly forming the second or more patterns by means such as a thermal head, a hot stamp, or printing, a multicolored (two or more colors) clothing cloth label can be easily and quickly prepared.
