Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a transfer printing method. More specifically, the present invention relates to a method of performing dry transfer printing using a continuous transfer printing machine using sheet-fed dry transfer printing paper.

<Conventional examples and their problems> Sheet-leaf transfer paper and roll-form, or continuous i-shashi, are conventionally known as dry transfer printing paper.Sheet-leaf transfer paper is mainly used for offset printing, silk screen printing, etc. Continuous transfer paper is usually printed using a gravure printing method, a flexible printing method, or the like.

In addition, sheet transfer paper is usually used for flat pressure transfer printing machines, while continuous transfer paper is generally used for transfer printing using a continuous transfer printing machine that uses a heating cylinder. be.

A feature of sheet-fed transfer paper is that because it is a sheet-fed transfer paper, it can be set at any desired position on the object to be transferred, and only an arbitrary portion can be printed. That is, FIG. 1(a),
(b) As shown in VC', a sheet-fed transfer paper (21) of an arbitrary shape is placed on an arbitrary part of the transfer target (1), and it is possible to partially print the sheet-fed transfer paper. Now, it is possible to transfer and insert other designs with different hues, patterns, and shapes into the entire surface pattern.In other words, as shown in Figure 2 (3)'
indicates the first transfer paper, (31 indicates the base paper, (62 indicates the ink layer printed on it), (3) indicates (3)
The second sheet-fed transfer paper partially provided in the transfer paper of '' is shown, (3 is the base paper, (3υ is the ink layer with other hues printed once on it) When these two transfer papers are laminated and transfer-printed onto the transfer object (4), the transfer paper ((1)
), and a pattern (41) having other hues and patterns due to the transfer paper (3) is formed.

This method is unique to transfer printing, and a flat-pressure dry printing machine is usually used.

When attempting to perform transfer printing on an arbitrary portion of an object to be transferred using such sheet-fed transfer paper using a continuous transfer printing machine, the following problems arise.

In other words, since the transfer area of flat-pressure transfer machines is horizontal, the transfer paper can be printed on the desired area of the object without being moved, even if the transfer paper is not forcibly held. can. On the other hand, if you try to print any part of the object to be transferred in the same way using a continuous transfer machine for the purpose of increasing the efficiency of transfer speed, the sheet of transfer paper tends to shift and move because the transfer part is not horizontal. It is necessary to forcibly hold the transfer paper in some way.

As a means for this purpose, a method of fixing the sheet-fed transfer paper using Sellotape or double-sided adhesive tape can be considered. In other words, Figure 3 shows an example in which a sheet of transfer paper is held with cellophane tape. has been done. (32) shows the pattern on the transfer paper (3).

In this method, the pressure-sensitive adhesive applied to the cellophane tape (5) is transferred onto the transfer object due to hot pressure during dry heat transfer, causing adhesive stains on the product, which poses a problem. On the other hand, Figure 4 shows an example in which sheet-fed transfer paper is fixed to a support such as back paper (1) using double-sided adhesive tape (6). ) is the back paper (11
It is fixed on top with double-sided adhesive tape (6). (32) shows the pattern (ink layer) on the transfer paper (3), and (4) shows the object to be transferred. In this case, the transferred object (
4) In the above printed patterns (41) and (45), a pressure difference occurs between the areas with and without the double-sided adhesive tape on the back side of the transfer paper, resulting in uneven color development in the printed patterns.

In other words, the pressure in the area indicated by (43) above (4) is lower than that in the area indicated by (4), so the dyeing density will be slightly lower.

Furthermore, in any of the above cases, if the adhesion holding force is insufficient, the transfer paper is likely to move during transfer, resulting in various troubles.

When attempting to perform dry transfer printing using sheet-fed dry transfer printing paper in a continuous transfer printing machine, various troubles occur, and improvements have been desired.

<Object of the Invention> The present invention was invented in view of these problems and is a novel invention with extremely high practicality.

<Summary of the Invention> That is, the present invention provides a method for performing dry transfer printing in a continuous transfer printing machine using sheet-fed dry transfer printing paper, in which the sheet-fed dry transfer printing paper and the transfer target are transferred into sheets. A continuous thin paper (13) from the back side of the leaf transfer paper is sandwiched with another continuous thin paper (13) from the back side of the transferred object, and the continuous thin paper (5) and (by the tension of Bl only) The sheet-fed dry transfer printing paper and the object to be transferred are closely polymerized, and the laminated/layered polymer is introduced into a continuous transfer printing machine, and transfer printing is performed by applying heat and pressure for a certain period of time. This technology provides a transfer printing method that uses cellophane tape,
A beautiful printed fabric with high commercial value can be obtained without using double-sided adhesive tape.

<Explanation of specific example> Hereinafter, the present invention will be explained using the drawings.

Figure 5 explains a part of the embodiment of the present invention, that is, (8) shows the main body of the continuous transfer printing machine, 03) shows the heating cylinder, (the force is an endless belt, and (1) shows the main body of the continuous transfer printing machine. Continuous thin paper roll (5) is shown, and (2) is a continuous paper roll (back paper) 9 that is supported from the back side of the transferred object.
3) is shown. (4) shows the cloth that is the transferred material, (33) shows the state in which sheets of dry transfer printing paper are piled up, and (
3) shows a sheet of transfer paper taken out from (33).

(15) is a sheet-fed transfer printing paper positioning surface plate, Q41 is a belt that conveys the fabric to be transferred, (9) is the bank paper (B) after transfer is completed, and (10) is after transfer is completed. Thin paper roll @ indicates prisoner. (1υ indicates the fabric that has been transfer printed, (12I indicates the remaining sheet of sheet-fed transfer printed paper after transfer.

That is, the position and parallelism of a sheet of transfer paper (3) taken out from a stack of sheets of transfer paper (kudzu) is determined by lightly touching the tip of the sheet of transfer paper (3) to the positioning surface plate (15). After that, the gravity of the transfer paper (3) gently moves the transferred cloth (1
1) The transfer paper placed thereon is conveyed to the entrance Y of the continuous transfer machine by a conveyor belt α4. At this point Y, there is a continuous thin paper (5) from the back side of the sheet-fed transfer paper (11 and the transfer object (
4) of the continuous thin paper (2) from the back side (the transfer paper and the fabric are sandwiched by Bl and introduced into the transfer machine (8) in a stacked state. Here, the sheet-fed transfer paper] 3) The material to be transferred (4
), and a beautiful pattern is printed without shifting during transfer. Therefore, there is no need to worry about adhesive stains or uneven dyeing caused by Sellotape or double-sided adhesive tape.

In the present invention, the continuous thin paper (A
) (The effect can be further enhanced by using continuous dry transfer printing paper as 11. In other words, as mentioned when explaining FIG. The following patterns can be inserted continuously as desired, and a beautiful printed pattern that cannot be obtained with any other method can be obtained.In addition, by using dry transfer paper as the thin paper (5) in (1), the following can be achieved. As is well known, dye ink on transfer paper basically consists of a dye and a binder). Here, the binder for holding this dye on the transfer paper is usually made of thermoplastic resin, and by holding the sheet-fed transfer paper from the back side with a continuous transfer paper, it is possible to maintain the heat and pressure on the sheet-fed transfer paper during transfer. The continuous transfer paper temporarily adheres to the paper, making it even more difficult for the sheet transfer paper to shift during transfer.

The continuous thin paper (5) or (I3) described in the present invention is inexpensive, relatively strong, and mildewy; specifically, kraft paper having a yield of about 50 to 80 ji/rrt is preferably used.

Further, when dry transfer paper is used as the continuous thin paper sheet, it is sufficient to print on kraft paper of about 60 to 80 ji/m'' with an ink containing a sublimable dye and a thermoplastic resin binder.

As a sheet-shaped transfer paper, it is desirable to use a relatively heavy base sheet, for example, 100 jj / 71? Preferably, the above-mentioned coated paper is printed with an ink containing a sublimable dye. Printing may be carried out by any method, but the features of the present invention are particularly useful when printing is difficult without sheet-fed printing, that is, when printing high-quality and elaborate designs.

As described above, the present invention provides a method for obtaining a good printed product using a continuous transfer machine with a high transfer speed using a sheet-fed dry transfer paper using an extremely simple method V, and is suitable from a practical point of view. It is also excellent.

The present invention will be explained below with reference to Examples.
