Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to the surface of various cloth sheets used for clothes such as T-shirts, cloths for clothes and bags.
Alternatively, the present invention provides a method for transferring a picture, a character, a symbol, or the like to the surface of a building material, a furniture material, or the like, and particularly a method for transferring a print having a small area.

[0002]

2. Description of the Related Art Various dyeing processes are used for woven fabrics and knitted fabrics manufactured in large quantities. Characters and symbols are usually printed on the surface of the cloth or cloth sheet used for bags and the like. For example, various pictures, characters and symbols, especially characters of various organizations, names and figures of manufacturers, etc. are printed on the surface of T-shirts, which are important patterns of T-shirts and improve their commercial value. In this sense, the printing is important.

Printing on this T-shirt rarely prints the same pattern or characters on a large number of shirts, and various designs are adopted according to sex, age, and application.
In this way, printing on T-shirts often involves printing a small amount of a small area consisting of pictures, patterns and symbols of different designs, such as the printing method and screen printing used for ordinary clothing fabrics. The method is rarely applied, and transfer printing suitable for large-scale low-volume production is adopted.

[0004]

In transfer printing, a printing layer (ink layer) is formed by printing pictures or patterns or symbols on the surface of a carrier paper (release paper or mount) entirely or locally. A transfer sheet formed by forming a thermal adhesive layer on the surface of the print layer for attaching the print layer to a material to be printed such as a T-shirt, and taking it into small transfer sheet pieces in consideration of workability and quality of a heat press or the like. Is used.

In the transfer sheet having such a structure, the thermal adhesive layer is brought into contact with the surface of an object to be printed such as a T-shirt, and hot pressing is performed on the carrier paper to form the printing layer via the thermal adhesive layer. Transfer printing is performed on the surface of a printed material such as a T-shirt. As this carrier paper, opaque or translucent paper, such as glassine paper, is used. On the back side of this paper, the back side of the heat-sensitive adhesive layer and the printing layer can be seen, but the normal side from the front side. The state of the print layer cannot be observed and must be seen through carefully. However, since the print layer is viewed through the opaque or translucent paper as described above, the print layer can be seen only faintly, and it is difficult to observe the accurate print state.

On the other hand, when the printing layer is formed in color, it is necessary to carry out the printing operation a plurality of times, and the carrier paper can be used to observe the state of the printing layer, and in order to make it easier for heat to pass, Since thin and thin ones are used, there will be differences in dimensions due to various conditions such as humidity and tension during transfer printing and the state of the printing machine. Print misalignment will occur. When the printing shift (plate shift) occurs, the transfer sheet becomes a defective product.

Therefore, it has been proposed and practiced to use a transparent synthetic resin film as a carrier paper in order to form a highly accurate printed layer by observing the state of the printed layer through the carrier paper. However, there is another problem here. That is, the transfer film is designed and manufactured by a maker capable of printing the transfer film. Usually, the transfer film is transferred to clothing such as a T-shirt by a sewing maker such as a T-shirt maker or a transfer processor. is there. When the transfer process is completed as described above, the carrier paper becomes scraps, but when a synthetic resin film is used instead of paper, this synthetic resin film also becomes scraps. If the waste is paper, the sewing manufacturer can burn it in an incinerator and dispose of it, or dispose of it as paper waste. However, in the case of synthetic resin film scraps, it is not possible to incinerate the film scraps due to problems of pollution and securing of resources, and it is necessary for the manufacturer of the transfer sheet to collect the film scraps. I am doing it.

A large amount of this film scrap is generated according to the production amount in the transfer process, and the film scrap after transfer becomes bulky, requires a large storage space, and interferes with the work. It is desired to dispose of the film waste early. On the other hand, the film scraps account for about 25% of the manufacturing cost of the transfer film (transfer sheet), and discarding the film waste causes considerable waste.

The present invention provides a transfer film and a transfer method thereof, which solve the above-mentioned drawbacks of a transfer film using a synthetic resin film as a carrier paper, and further the drawbacks of a transfer sheet using paper. The purpose is.

[0010]

The transfer film and the transfer method thereof according to the present invention for achieving the above object are as follows. 1) A transfer film in which a print layer is formed by performing predetermined printing of pictures, characters, symbols, etc. on a heat-adhesive film, and there are a long film and a transfer film which is cut into small pieces.

2) A picture, letters, symbols, etc. can be attached to the heat-adhesive film.
For example, a transfer film base material on which a printing layer is formed by printing characters, scenery, etc., that is, a long sheet-like or small piece-like sheet piece is cut around the character etc. to a predetermined size. It is a separated transfer film piece. 3) The heat-adhesive film is usually used as a heat-adhesive film or a heat-adhesive which can be adhered by heating an iron for clothing, and its form disappears when heated by an iron or the like. What has a characteristic that does not give a feeling of strangeness is used.

The heat-adhesive film may be one which can be continuously printed by using a long sheet-like material, or one which is a small piece for easy printing on a small printing machine. It is preferable to use a transfer film piece that has a small area and can be heated all at once in a hot press operation by cutting around the printing area such as a character. Therefore, it is preferable that the cut portion of the heat-adhesive film is slightly inside the edge portion of the printed portion and that the heat-adhesive film does not protrude beyond the printing.

4) A step of producing a continuous or small-area transfer film base material having a printing layer formed by printing a heat-adhesive film with a predetermined print such as a picture, a character or a symbol, and the printing of the transfer film base material. A step of producing a transfer film piece by cutting the periphery of the portion and separating it from the transfer film base material; a step of applying the surface of the transfer film piece on the side of the heat-adhesive film to the surface of the transferred object; And a step of pressing a heating body from the printing surface side to melt the heat-adhesive film and transfer the printing layer to a transfer target.

5) A release layer or a release sheet is previously fixed or attached to the surface of a heating body such as an iron for press or a heating roll, and a transfer film piece is inserted through this releasing sheet. It is good to supply heat to. In a normal transfer process, it is preferable to transfer-print by using a press iron and a transfer film piece. In the case of mass production, a long transfer film is used to continuously send it to the transfer process, and locally heats it with a heating roller or a pressing body that has a locally protruding heating part and heats the non-printing part. It is also possible to adopt a method in which the adhesive film is a scrap film and the scrap film is heated and melted to reduce the volume.

6) The transfer film piece is one united picture or character, for example, character, etc., and the print portion of the picture or character is designed to have a size capable of being hot pressed all at once in the hot pressing step. For example, when an iron is used for a heating press, it is preferable to use a transfer film piece having an area smaller than the pressing surface of the iron. For example, one T-shirt may have a plurality of pictures, letters, etc. Printing deviation does not occur at all even when printed on, and this makes it possible to cope with the case where different types of products are produced in small quantities.

[0016]

[Operation] In the transfer sheet of the present invention, a release sheet is not laminated, and a waste film is not generated by heat transfer onto a printing material. In particular, when the transfer film piece is used for transfer, the transfer can be easily carried out by a usual ironing process or a heat pressing process. In a special case, a long transfer sheet may be used, and even in this case, the waste film is a heat-bonding film, and its capacity may be significantly reduced by heating, causing a problem in post-processing. Absent.
