The pigment is printed on the uniform fabric through the plate. The specified image layer is printed on the transfer paper or pet film with the silk screen using the pigment dedicated to thermal transfer, and the transfer paper etc. is thermally transferred onto the uniform fabric. There has been a method of attaching a mark fabric to a fabric by thermocompression bonding by welding using high frequency.

[0004] In addition, a relatively frequently used color is solid-printed on a roll-shaped thermal transfer paper, and the thermal transfer paper is cut using the output of personal computer data, so that the design of the entire uniform design and the necessary team names, etc., are printed. There is also a method in which a marking is produced, a uniform fabric is superimposed on the marking, and the marking is transferred by pressing with a hot press machine.

[0005]

However, such a conventional method of marking on uniforms and other fabrics has its own limitations in terms of design expression in order to take advantage of its diversity. Also, in the marking processing of numbers and numbers, it has been difficult to respond to various requests from the market.

[0006] In addition, in the conventional marking methods, the mark fabric or the like is processed by overlapping on a cloth such as a uniform, so that when worn, it is somewhat heavy and uncomfortable. Furthermore, if used for a long period of time, there is a possibility that peeling, cracking, etc. may occur at the marking portion.

Therefore, the sublimation thermal transfer marking method for fabric of the present invention has been made to solve such problems of the conventional marking method, and a pattern is formed by silk screen printing using a sublimation dye on the fabric. The image of the thermal transfer paper on which is printed with the fabric is superimposed, the heat treatment is performed by vacuum thermal transfer, and the marks such as the team name and number can be transferred at the same time. It is intended to provide.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a sublimation thermal transfer marking method for fabrics according to an embodiment of the present invention.

As shown in FIG. 1, in the method of sublimation thermal transfer marking of fabric of the present invention (named by the present inventors as "sublimation marking system"),
First, a thermal transfer paper (for example, a special paper with an intermediate coat) that is suitable for the size of a cut cloth of a uniform (for example, 1420 mm × 920 mm) as a product is prepared, and becomes a base for forming the entire design on the thermal transfer paper. Performs transfer paper printing of images (designs). For this transfer paper printing, an image (base pattern) is printed on a sheet-like transfer paper with an ink containing a sublimation dye (for example, a sublimation-type disperse dye for silk screen) using silk screen printing using a plate. (Process). Here, gravure printing and offset printing can be used in addition to silk screen printing.

On the other hand, transfer paper printing required for marking a team name, a number, etc. (mark) on a uniform is performed by first forming a heat transfer paper having a seal-like two-layer structure (made of a two-layer structure of transfer paper and seal paper). A transfer sheet in the form of a seal is prepared, and solid printing is performed on the two-layered thermal transfer paper using an ink containing a sublimation dye at the same level as the above-mentioned step by using silk screen printing (step). Here, the team name, number, etc. (mark) of the uniform used for the marking process are input to a personal computer in advance, and necessary images (designs) are formed therein, and these data are written. Basically, the papers are arranged so that they can correspond to the thermal transfer paper one by one, and output by a separately provided plotter. Here, whether to output the image to transfer paper by the inkjet method,
Alternatively, an image may be output using a color copier by converting the sublimation dye into a toner. Then, cutting is performed to cut the necessary mold. For this purpose, necessary characters or numbers are cut into the surface of the thermal transfer paper, and after the cut is completed, unnecessary portions are peeled off by hand and discarded.

[0012] Next, a transparent film is prepared, a lightly viscous bond is sprayed on the surface, and the surface is subjected to a paste processing having a weak viscosity. , Number, etc., are lightly pressed against the mark portion on the printed surface of the two-layered thermal transfer paper on which the images (marks) are printed on a film, for example, a PET (PE).
T, polyethylene terephthalate) film, and pick up mark film on it (process).

Further, on the thermal transfer paper on which the design of the entire uniform printed with the pattern in the process described above is formed,
After the marking position is determined in advance, the mark film created in the above-described process is overlaid and pasted (process).

On the other hand, fabrics (fabrics) used as materials for uniforms, for example, white polyester fabrics, mesh-like fabrics, cotton fabrics, polyester / cotton blended fabrics, silk fabric fabrics, etc., having good coloring and fastness. The paper is cut to a size that can be inserted into the polyester fabric transfer machine, or the paper is cut in advance so as to fit the body front and rear, sleeve left and right. Then, the cut cloth (fabric) is superimposed on the large-cut cloth of the thermal transfer paper and the mark film prepared in the above-mentioned process, and is subjected to a sublimation thermal transfer machine in a temperature range of 185 to 200 ° C, for example, about 195 ° C. A vacuum (e.g., 690-715) at a temperature of at least 40 seconds (evacuation takes about 20 seconds more).
Heat treatment is performed under Torr (step).

[0015] By this heat treatment, the printed portion of the design and design (marks of characters, numbers, etc.) previously printed on the thermal transfer paper and the mark film at the same time is sublimated (vaporized) by the sublimation dye, and the fabric, eg, polyester It adheres and penetrates to the molecular level of the system and is fixed, and the previous printed portion is clearly transferred and marked on the fabric. Here, in the sublimation transfer machine used in this step, since the thickness of the fabric to be subjected to the marking process is relatively small, the volume of the vacuum chamber for accommodating the fabric can be made extremely small. The pressure inside the vacuum chamber can be reduced in a short time by a pump. Note that heat treatment may be performed at normal pressure.

Finally, a predetermined pattern is applied to cut and sewn to form a finished product on sportswear such as a uniform.

[0017]

According to the sublimation thermal transfer marking method of the present invention, marking on uniforms and other sportswear is performed easily, quickly and with versatility by sublimation thermal transfer. Can be greatly changed and various designs can be expressed, so that it is possible to easily meet the demands of a low-cost and diverse market.

In addition, the marking process is relatively simple, and no water is required for printing ink. Further, the reproducibility of the marking process is increased.

Further, since the marking process is performed by sublimation heat transfer, when wearing a sports uniform for a game, it feels extremely light and does not feel uncomfortable. Furthermore, even when worn as a uniform for a long time, there is a remarkable effect that there is no peeling or cracking of the marking portion, and there is no unevenness on the fabric, and the characteristics of the fabric material can be brought out as it is.
