DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0014] FIG. 1 shows a laminate 1 according to an embodiment of the present invention, where (A) is a plan view of the laminate 1, (B) is a cross-sectional view taken along line ii in (A), and (C) is a cross-sectional view taken along line ii-ii in (A).

[0015] The laminate 1 according to this embodiment includes a fiber sheet 2 which is a printing material, and a base sheet 3 , and the fiber sheet 2 is adhered to the surface of the base sheet 3 by an adhesive 4 .

[0016] The fiber sheet 2 is a nonwoven fabric, knitted fabric, or woven fabric made of fibers, and the fibers that make up the fiber sheet 2 can be, for example, cotton, wool, hemp, pulp, mineral fiber, chemical fiber, rayon fiber (regenerated fiber), nylon fiber, polyester fiber, polypropylene fiber, acrylic fiber, aramid fiber, and blends thereof.

[0017] The base sheet 3 is a sheet made of paper, polyethylene terephthalate (abbreviated as PET), or polypropylene (abbreviated as PP). In the present invention, paper refers to a sheet made of pulp, and the raw material of the paper constituting the base sheet 3 can be, for example, wood pulp, recycled paper pulp, or non-wood pulp. The wood pulp can be softwood pulp or hardwood pulp. The non-wood pulp can be straw pulp, bagasse pulp, reed pulp, kenaf pulp, mulberry pulp, or fruit pulp (fibrous material such as mesocarp, canola membrane, or sieve of citrus fruits such as oranges, mandarins, grapefruits, and apples). The adhesive 4 can be, for example, an acrylic, rubber, or silicone adhesive.

[0018] The fiber sheet 2 and the base sheet 3 are rectangular and have approximately the same dimensions. The outer peripheral edge 2a of the fiber sheet 2, the width bisector 2b of the fiber sheet 2, and the length bisector 2c of the fiber sheet 2 are bonded to the base sheet 3 by the adhesive 4. The outer peripheral edge 2a is a ring-shaped portion of a predetermined width along the outer peripheral edge of the fiber sheet 2. The width bisector 2b is a linear portion of a predetermined width along a line that bisects the fiber sheet 2 in the width direction. The length bisector 2c is a linear portion of a predetermined width along a line that bisects the fiber sheet 2 in the length direction. The range of the fiber sheet 2 bonded to the base sheet 3 is not limited to the above-mentioned portion. For example, the outer peripheral edge 2a of the fiber sheet 2, the first diagonal portion of the fiber sheet 2, and the second diagonal portion of the fiber sheet 2 may be bonded to the base sheet 3 by the adhesive 4. The first diagonal portion is a linear portion of a predetermined width along one diagonal of the fiber sheet 2. The second diagonal portion is a linear portion of a predetermined width along the other diagonal of the fiber sheet 2. Only the outer peripheral edge portion 2a of the fiber sheet 2 may be adhered to the base sheet 3 by the adhesive 4, or the entire fiber sheet 2 may be adhered to the base sheet 3 by the adhesive 4. The fiber sheet 2 may be adhered to the base sheet 3 in a spot or grid pattern by the adhesive 4. The dimensions and shapes of the fiber sheet 2 and the base sheet 3 are not limited to the above dimensions and shapes, and may be set to any dimensions and shapes that allow printing on the fiber sheet 2 in a state where the fiber sheet 2 is adhered to the base sheet 3.

[0019] FIG. 2 is a schematic cross-sectional view showing a method of printing the fiber sheet 2 included in the laminate 1 according to this embodiment using a printer 10.

[0020] The screen printing machine 10 includes a printing table 11, a screen plate 12 arranged above the printing table 11, a squeegee 13 arranged above the screen plate 12, and a positioning means 15. In the screen printing machine 10, the positioning means 15 can position the printing material on the printing table 11 and the squeegee 13 can slide on the screen plate 12, and the screen plate 12 has through holes 14 formed therein that have a shape corresponding to the printing pattern.

[0021] The positioning means 15 comprises a plate 16 extending upward from the printing table 11, and a claw portion 17 tiltably provided on the upper end of the plate 16. The positioning means 15 positions the printing material on the printing table 11 by bringing the edge of the printing material into contact with the plate 16, and by tilting the claw portion 17 to pinch the edge of the printing material between the claw portion 17 and the printing table 11, the printing material is fixed in a positioned state.

[0022] When printing on the fiber sheet 2, the laminate 1 is placed on the printing table 11 so that the fiber sheet 2 is located on the screen plate 12 side (upper side) and the base sheet 3 is located on the printing table 11 side (lower side). With the edge of the laminate 1 in contact with the plate material 16, the claws 17 are tilted to sandwich the edge of the laminate 1 between the claws 17 and the printing table 11, thereby positioning and fixing the laminate 1 on the printing table 11. In this state, ink 20 is supplied onto the screen plate 12 and the squeegee 13 is slid over the screen plate 12, whereby the ink 20 is discharged from the through holes 14 and applied to the fiber sheet 2, thereby printing on the fiber sheet 2. In the illustrated printing press 10, a pair of squeegees 13A, 13B are provided as the above-mentioned squeegee 13, and the squeegees 13A, 13B are capable of moving to one side A (opposite side of the positioning means 15) of the printing table 1 and to the other side B (toward the positioning means 15) of the printing table 1. While the squeegees 13A, 13B are moving to the one side A, the squeegee 13A slides on the screen plate 12, and while the squeegees 13A, 13B are moving to the other side B, the squeegees 13A, 13B are capable of rising and falling, respectively, so that the squeegee 13B can slide on the screen plate 12.

[0023] According to this embodiment, the fiber sheet 2 is adhered to the base sheet 3 which is paper, a sheet made of polyethylene terephthalate, or a sheet made of polypropylene, and thus it is possible to suppress bending of the fiber sheet 2 caused by contacting the edge of the laminate 1 with the plate material 16 of the positioning means 15. Therefore, the laminate 1 according to this embodiment is suitable for positioning the fiber sheet 2 by the positioning means 15, and therefore the printing method of the fiber sheet 2 provided in the laminate 1 described above is suitable for printing at a desired position on the fiber sheet 2 (suitable for applying ink 20 to a desired position on the fiber sheet 2).

[0024] The present invention is not limited to the above embodiment, and may be modified in various ways. In the following, the modified examples of the present invention will be described focusing on the differences from the above embodiment, and the same reference numerals as the above embodiment will be used to denote the same points, and the description thereof will be omitted.

[0025] For example, the positioning means provided in the screen printing machine 10 shown in the above embodiment is not limited to the positioning means 15 shown in FIG. 2, and may be various means for positioning the printing material on the printing table 11 by contacting the edge of the printing material. When this type of positioning means is provided in the printing machine 10, in order to print the fiber sheet 2, the laminate 1 is placed on the printing table 11 so that the fiber sheet 2 is located on the screen plate 12 side and the base sheet 3 is located on the printing table 11 side, and the edge of the laminate 1 is brought into contact with the positioning means to position the laminate 1 including the fiber sheet 2 on the printing table 11. In this state, ink 20 is supplied onto the screen plate 12, and the squeegee 13 is slid on the screen plate 12, so that the ink 20 on the screen plate 12 is discharged from the through holes 14 of the screen plate 12 and applied to the fiber sheet 2.

[0026] Also, a screen printer 30 shown in Fig. 3 may be used instead of the screen printer 10 shown in Fig. 2. The screen printer 30 includes a positioning means 31 in addition to the printing table 11, the screen plate 12, and the squeegee 13 shown in the above embodiment.

[0027] The positioning means 31 sucks the printing material to position it on the printing table 11. The positioning means 31 includes a plurality of suction holes 32 formed in the printing table 11 and a suction device (not shown) connected to each of the suction holes 32, and each of the suction holes 32 opens on the upper surface of the printing table 11. As the suction device, for example, a suction device equipped with a vacuum pump is used.

[0028] When printing on the fiber sheet 2, the laminate 1 is placed on the printing table 11 so that the fiber sheet 2 is located on the screen plate 12 side (upper side) and the base sheet 3 is located on the printing table 11 side (lower side), and the above-mentioned suction device is operated to suck the base sheet 3 through the suction holes 31, thereby positioning the laminate 1 on the printing table 11. In this state, ink 20 is supplied onto the screen plate 12 and the squeegee 13 is slid over the screen plate 12, whereby the ink 20 is discharged from the through holes 14 and applied to the fiber sheet 2.

[0029] When printing on the fiber sheet 2 using the above-mentioned printing machine 30, the base sheet 3, which is paper, a sheet made of polyethylene terephthalate, or a sheet made of polypropylene, can be fixed by suction with the positioning means 31, so the laminate 1 is suitable for positioning the fiber sheet 2 with the positioning means 31, and therefore the printing method for the fiber sheet 2 provided in the above-mentioned laminate 1 is suitable for printing at a desired position on the fiber sheet 2 (suitable for applying ink 20 to a desired position on the fiber sheet 2).

[0030] The printer 30 may be one that sends the laminate 1 wound around a driven roller (not shown) to the driving roller by driving the driving roller (not shown). In this case, the part of the laminate 1 between the driving roller and the driven roller is placed on the printing table 11 and positioned by suction of the positioning means 31. Then, the ink 20 is applied to the area of ​​the fiber sheet 2 on the part of the laminate 1 to perform printing. [Explanation of symbols]
