Abstract

PURPOSE:To faithfully realize the color and pattern of a manuscript by applying printing to cloth in a lining paper bonded state by an offset press or a photogravure press. CONSTITUTION:Lining paper 2 is bonded to cloth 10. Therefore, when printing is applied to the cloth 10 by an offset press or a photogravure press or the cloth 10 is fed, it is prevented that the cloth 10 is wrinkled or bent by the nerve of the lining paper 2. Since the printing to the cloth 10 is performed by the offset or photogravure press, the reproducibility of the image of a manuscript becomes extremely high.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a printing method for printing patterns, photographic images, and other printed patterns onto cloth for clothing.

[Conventional technology]

Conventionally, screen printing is generally used to add printed patterns to fabrics. In this screen printing, first, a printing screen is created for each color of the image to be reproduced, and colored paste is made by mixing pigments and one-dimensional paste. Then, for each color, a corresponding screen is placed on the fabric and printing is performed using the corresponding color paste. After printing, the fabric is heat-treated with steam to develop the pigment and increase its durability. Furthermore, the fabric after heat treatment is washed with water to wash away glue and unnecessary pigments. As a result, patterns and the like are printed on the fabric.

[Problem to be solved by the invention]

However, in the case of patterning by screen printing,
Since printing is performed through a screen, there is a problem in that it is difficult to reproduce fine patterns. Further, there is a problem in that post-treatments such as heat treatment and water washing treatment are required after printing. Further, during this heat treatment, harmful formalin is generated from trimitylolmelamine, which is a coagulating agent contained in the pigment. Furthermore, even after washing with water, some formalin remains, making it impossible to print on infant clothing, for which the amount of residual formalin is legally regulated. Furthermore, in the case of patterning by screen printing, in order to increase the number of reproduced colors, it is necessary to create the same number of printing screens and secure a place to place these screens, which requires large-scale equipment. . For this reason, there are problems in that the equipment becomes expensive and that it is difficult to handle clothing patterns in small lots. Furthermore, if the number of printing screens is reduced in order to simplify the equipment, a problem arises in that the reproducibility of original images is significantly degraded.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to make it possible to print a fine pattern on a fabric using a simple process, and to prevent harmful substances from remaining on the fabric after the pattern is formed.

[Means to solve the problem]

In order to achieve the above object, the method of printing on fabric of the present invention involves pasting a backing paper onto the fabric and printing on the fabric with the backing paper attached using an offset printing machine or a gravure printing machine. It is characterized by

[Effect]

According to the present invention, since the backing paper is attached to the fabric, when the fabric is printed or conveyed by an offset printing machine or a gravure printing machine, the stiffness of the backing paper prevents the fabric from wrinkles. It will no longer bend or bend.

Further, since printing on the fabric is performed by offset printing or a gravure printing machine, the reproducibility of the original image is extremely high. Furthermore, since the ink used in offset printing or gravure printing machines does not contain harmful formalin, no harmful substances remain on the fabric after printing. After printing, you can peel off the backing paper from the fabric and use it as a normal printed fabric.

〔Example〕

DETAILED DESCRIPTION OF THE INVENTION Hereinafter, features of the present invention will be specifically described based on examples with reference to the drawings.

Fig. 1 is a schematic side view showing a lining device used in one step for carrying out the method of printing on fabric of the present invention, Fig. 2 is an enlarged sectional view showing the fabric after lining, and Fig. 3 is a FIG. 2 is a schematic side view of an offset sheet-fed printing machine that prints on cloth after lining.

The lining device shown in FIG. 1 is for attaching lining paper to the back side of fabric. A base paper 2 having a thickness of 0.15 mm, for example, pulled out from a base paper roll 1 is turned around by a guide roll 3 and passes through a gluing device 4 section. The gluing device 4 includes a pair of gluing cylinders 41 and 42 which sandwich and pass the base paper 2, and a gluing device 41, which supplies liquid adhesive G to the surface of one gluing cylinder 41. A doctor 44 is provided for controlling the abrasion of the adhesive G adhering to the pot 43 and the gluing cylinder 41. In addition, as a component of this adhesive G, acrylic copolymer 1 synthetic drying oil, rubber type can be used, and the viscosity is 25'/1000 cps.
~3000 cps is desirable. The above-mentioned components are mixed to obtain an adhesive G having desired characteristics with a water ratio of 40 to 50%.

The base paper 2 that has passed through the gluing device 4 is passed through the guide roll 5. Dryer 6. It passes through a guide roll 7 and further passes through a bonding device 8 section. The bonding device 8 is composed of a pair of bonding cylinders 81 and 82, and passes the base paper 2 and the raw fabric 10 pulled out from the raw fabric roll 9 while sandwiching it therethrough, and attaches the lining fabric 11 thereto. create.

This backing raw fabric 1] is wound up on a winding roll 12.

Next, the gluing and bonding operations of the above-mentioned lining device will be explained.

The base paper 2 pulled out from the base paper roll 1 passes between a pair of gluing cylinders 41 and 42;
1 is rotating in contact with the liquid adhesive G contained in the glue pot 43, so the adhesive G is attached to its surface. Therefore, when the base paper 2 passes between the pair of gluing cylinders 41 and 42, the adhesive G adheres to one surface of the base paper 2. At this time, the thickness of the adhesive G can be adjusted by adjusting the position of the doctor 44.

Next, the base paper 2 to which the adhesive G has been adhered passes through a guide roll 5 and a smoke dryer 6, and is dried to such an extent that the adhesive G has an appropriate viscosity. The dried base paper 2 passes between the bonding cylinders 81 and 82 together with the raw fabric 10 from the raw fabric roll 9, but the adhesive G is attached to the raw fabric 10 side of the base paper 2. Therefore, as shown in FIG. 2, the base paper 2 is pasted on the back side of the base fabric 10. The raw fabric backed with the base paper 2 in this manner, that is, the lining raw fabric 11 is wound onto a winding roll 12. At this time, in order to run the lining material 11 stably, it is necessary to make the width of the base paper 2 wider than the width of the material 10.

Next, this roll-shaped backing fabric 11 is cut into a size that can be printed on a normal offset sheet-fed printing machine using an appropriate cutting device (not shown), for example, 1456 mm x called B double size. Cut into offset sheets with a size of 1030 mm.

Next, the backing fabric cut into offset sheets as described above is loaded with the fabric side up on the paper feed section 13 of a commonly used offset sheet-fed printing machine as shown in FIG. The paper is taken out and sequentially passed through the printing units 14 to 17 for each color to print in each color, for example, yellow magenta, cyan, and black.

For example, in the printing unit 14, a plate material (not shown) on which a pattern to be printed is formed is attached to a plate cylinder 14a, and pigment-type ink is applied to the plate material. . The ink on the plate material is transferred to the rubber F 14 b, and then the printing material, that is, the sheet-like backing material, passes between the rubber cylinder 14b and the impression cylinder 14C, whereby printing is performed on the material side. After printing, the lining fabric is sent to the printing section 15 for the next color by the intermediate cylinder 14d. Printing for each color is performed in the same manner thereafter. The lining fabric that has been printed in each of the printing units 14 to 17 is discharged to a paper discharge unit 18. Incidentally, as the pigment-type ink used for printing in each printing section 14 to 17, offset printing ink DICM is used.
PX-15 can be used.

In each of the above-mentioned printing units 14 to 17, when printing and conveyance are performed, the fabric is lined with base paper 2 (see Figure 2), so the stiffness of the base paper 2 will affect the flatness of the fabric. is maintained and printed accurately without wrinkling or bending. Furthermore, since printing is performed using offset printing, even very fine patterns can be reproduced. Furthermore, since each color is reproduced by combining four colors, the number of printing steps does not increase even when there are many reproduced colors. Furthermore, since the ink used for offset printing does not contain formalin, post-processing such as washing with water is unnecessary, and problems due to residual formalin do not occur.

Next, by peeling the base paper from the backing fabric, a fabric with a pattern printed by offset printing is obtained. From this point on, the garment can be manufactured using normal processes.

In the above-described embodiment, printing was performed using an offset sheet-fed printing machine, but it is also possible to print on the lining material 10 in a roll form using an offset rotary printing machine. Furthermore, instead of offset printing, printing may be performed on the roll-shaped backing material 10 using a gravure printing machine.

〔Effect of the invention〕

As described above, according to the present invention, the fabric is lined and printing is performed using an offset printing machine or gravure printing, so that the colors and patterns of the original can be faithfully reproduced. Furthermore, since a general printing machine can be used as the printing device, existing equipment can be used, and the cost of equipment investment can be reduced.

Furthermore, since the dye is not dyed using raw materials containing formalin, no formalin remains and it can be used for printing clothes for infants.
