JPH0725189B2 - How to print an image on a cloth and cloth printed with an image - Google Patents

Description

Description: TECHNICAL FIELD The present invention relates to a method for printing an image on a cloth and a cloth on which the image is printed.

(Prior Art) Dyeing of a fabric with a dye cannot produce an image like a photograph.
Also, multi-color printing cannot be applied to fabrics that have large stretches because the fabric has irregularities.

It is only possible to print a photographic-like image on a cloth by means of a thermal transfer printing method with a slightly sublimable dye.
The public relations regarding this is as follows.

Japanese Patent Publication No. 39-18793 Japanese Patent Publication No. 4751732 Japanese Patent Publication No. 41-18308 Japanese Patent Publication No. 47-8010 Japanese Patent Publication No. 47-44054 All of these print an image on paper using a sublimable dye and print it on a cloth. By stacking and heating,
It is a method of dyeing a dye on a cloth by utilizing the sublimation property of a sublimable dye.

However, this method has the following major drawbacks.

(B) The sharpness of the image is far lower than that of the photograph.

(B) It has poor weather resistance and is easily discolored or discolored outdoors.

(C) This sublimation dye thermal transfer printing method is applied to almost all polyester fibers and has weak dyeing power to other chemical fibers and natural fibers.

(Problems to be Solved by the Invention) Since the conventional sublimation dye thermal transfer printing method for printing an image on a cloth has the above-mentioned drawbacks, the present invention is an improvement of this drawback, that is, it is clear as a photograph. Its purpose is to have strong weather resistance and to print beautiful images on any kind of cloth.

(Means for Solving Problems) Images printed on paper are beautiful like photos and are inexpensive. Using this property, a release agent is applied to the surface with the image, this surface is temporarily adhered to a smooth plate with an adhesive, and the paper on the back side of the printed matter is dissolved and removed with a pulp solution to expose the back side of the image. .

After adhering the back side of this image to the side of the cloth, the image is left on the cloth when the temporarily adhered plate is peeled off. The image is printed on paper as it is.

In addition, printing inks generally have stronger weather resistance than sublimable dyes, so that the above-mentioned object can be achieved.

(Example) Example 1 First, a target image is printed on a paper by a conventional multicolor printing method such as gravure printing or offset printing.

The image may be printed on the paper by the screen process, color copy, ink jet printer or electrostatic plotter method.

A release agent is then applied to the imaged side of the paper. The release agent may be either silicone-based or fluorine-based release agent.

Next, the surface having the image coated with the release agent is temporarily adhered to the smooth plate with an adhesive or an adhesive.

The concentration of the release agent may be adjusted so that the temporarily bonded plate can be appropriately removed, so that its concentration is adjusted appropriately.

Since the back side of the printed matter temporarily adhered to the plate is the front side, the back side of the image of the printed matter is exposed when the paper is dissolved and removed with a pulp solution, that is, an alkaline solution (5% caustic soda solution) or warm water.

Since the image of the printed matter formed by this ink is very thin, it is necessary to temporarily adhere it to the plate to reinforce it. Otherwise, if the paper underlying the image is melted and removed,
This is because the image made of ink that has lost its base will collapse.

Next, the back surface of the image of this printed material is adhered to the cloth surface with an adhesive.

Use cloth that has been subjected to shrink-proof treatment beforehand so that it will not shrink even if it gets wet with water.

For the adhesive, select one that adheres well to both the cloth material and the printing ink.

Through the above operation, the back side of this image is thermocompression-bonded to the cloth surface with a thermocompression-bonding adhesive.

Finally, when the temporarily bonded plate is peeled off, only the printed image composed of ink remains on the cloth surface.

That is, the image printed on the paper is directly printed on the cloth surface. If a thin transparent plastic film is coated on the ink of the image after printing on the cloth, the weather resistance becomes stronger.

Example 2 First, the target image is printed on paper by a conventional multicolor printing method.

The image may be printed on the paper by the screen process, color copy, ink jet printer or electrostatic plotter method.

Next, a transparent plastic film, for example, an acrylic resin film, is applied to the surface of the printed matter having the image. After drying, a release agent is applied to this surface. The release agent may be a silicone-based or fluorine-based release agent.

Next, the surface having the image coated with the release agent is temporarily adhered to the smooth plate with an adhesive or an adhesive.

The concentration of the release agent is appropriately adjusted so that the temporarily bonded plate can be easily removed.

Since the back side of the printed matter temporarily adhered to the plate is the front side, the back side of the image of the printed matter is exposed when the paper is dissolved and removed with a pulp solution, that is, an alkaline solution (5% caustic soda solution) or warm water.

The temporary adhesion to the smooth plate is for protection of the thin image composed of ink.

Next, the back surface of the image of this printed matter is adhered to the cloth surface with an adhesive. Following the same procedure as in Example 1, the back side of this image is thermocompression-bonded to the cloth side with a thermocompression-bonding adhesive.

Finally, when the temporarily bonded plate is peeled off, only the printed image composed of ink remains on the surface of the cloth. That is, the image printed on the paper is directly printed on the surface of the cloth.

In this embodiment, since a step of applying a plastic film for image protection is included in the steps, it is not necessary to process the plastic film after the process as in Example 1 is completed.
Image coating is for long-term use and may be omitted for short-term use.

The embodiments of Examples 1 and 2 will print a soft image integral with the fabric on the fabric. Moreover, this image is a beautiful image as it is printed on paper. Therefore, any image that can be reached by current printing techniques, even in the case of any image, can be printed on the cloth in this way with its sharpness.

(Effect of the invention) The features of the method and image of the present invention will be described in comparison with a sublimation dye thermal transfer printing method (hereinafter referred to as a sublimation printing method) capable of printing an image on a cloth.

(A) The image of the present invention printed on the cloth is far more beautiful and similar to the photograph as compared with the sublimation printing method.

(B) The weather resistance of the image of the present invention is stronger than that of the image obtained by the sublimation printing method.

(C) The sublimation printing method has a weak dyeing property on fibers other than polyester fibers. Especially, cotton, silk, wool, rayon, polyethylene fiber and polypropylene fiber have no dyeing property.

In addition, even if the same fiber is used, the color will differ if the weaving and knitting methods are different.

The image produced by the method of the present invention can be made of fibers of any material,
You can always print very beautiful images with any weave or knit method.

As described above, the characteristics of A, B, and C are the features of the present invention that have not been found in the past.
