[0001] This invention relates to a method for manufacturing a printing mesh and a printing screen made using the printing mesh, particularly to a method for manufacturing a monofilament printing mesh and a monofilament printing screen and a monofilament composite printing screen made using the monofilament printing mesh. Background Technology

[0002] In existing printing screen fabric technology, the commonly used weaving process involves cross-weaving warp and weft yarns. For example, the warp yarns are first stretched and passed through a reed, and then the weft yarns are woven to form a printing screen fabric. However, when printing on a screen made of cross-weft woven printing screen fabric, the ink often gets stuck at the cross-weft knots, ultimately degrading the quality of the printed pattern. Summary of the Invention

[0003] [The problem that the invention aims to solve]

[0004] In existing technologies, printing ink often gets stuck at the intersections of warp and weft yarns. Therefore, how to prevent warp and weft yarn intersections from forming in the printing screen has always been a problem that needs to be solved in printing screen technology.

[0005] [Technical means to solve the problem]

[0006] A method for manufacturing a monofilament printing mesh includes the following steps: stretching multiple yarns and straightening them; passing the straightened yarns through a reed for a first-stage spacing adjustment; passing the yarns through the reed through a reed fixture for a second-stage spacing adjustment; and pressing the yarns through the reed fixture with a polymer film layer to form the monofilament printing mesh, wherein the yarns all extend in the same direction and are parallel to each other.

[0007] Preferably, the reed fixture includes a plurality of guide grooves through which the yarn passes for the second-stage spacing adjustment.

[0008] Preferably, the width, depth, number, and spacing of the guide grooves are adjusted according to the diameter, quantity, and predetermined spacing of the yarns.

[0009] Preferably, the reed fixture is a planar reed fixture or a cylindrical reed fixture.

[0010] Preferably, the yarns are made of metal, and the yarns are multiple metal warp threads or multiple metal weft threads of the monofilament printed mesh.

[0011] On the other hand, the present invention also provides a monofilament printing screen, comprising: a screen frame; a monofilament printing screen fabric made using the manufacturing method described in the present invention, fixed on the screen frame and including a squeegee surface and a printing surface; and at least one open pattern formed on the monofilament printing screen fabric.

[0012] Preferably, the yarns are made of metal, and the yarns are multiple metal warp threads or multiple metal weft threads of the monofilament printing screen.

[0013] Furthermore, the present invention also provides another monofilament printing composite screen, comprising: a screen frame; a first material screen fixed on the screen frame; a monofilament printing screen fabric made using the manufacturing method described in the present invention, fixed on the first material screen and including a squeegee surface and a printing surface; and at least one open pattern formed on the monofilament printing screen fabric.

[0014] Preferably, the yarns are made of metal, and the yarns are multiple metal warp threads or multiple metal weft threads of the monofilament printing composite screen.

[0015] [Invention Benefits]

[0016] As described above, this invention provides a method for manufacturing a monofilament printing mesh, a monofilament printing screen, and a monofilament printing composite screen. The method, screen, and composite screen of this invention include using a two-stage positioning method to adjust the spacing between yarns. This positioning method effectively achieves the desired yarn spacing. Furthermore, this invention provides at least one open pattern on the monofilament printing mesh. This ensures that the open pattern does not include any warp or weft yarn intersections, eliminating the need for additional processes to remove other yarns, resulting in more complete graphics with better conductivity and improved printing yield.

[0046] The embodiments of the present invention will be described in more detail below with reference to the accompanying drawings and component symbols, so that those skilled in the art can implement them after studying this specification.

[0047] Figure 1 This is a flowchart illustrating a method for manufacturing a monofilament printing mesh according to an embodiment of the present invention; Figure 2 This is a schematic diagram illustrating the manufacturing process of a monofilament printing mesh fabric according to an embodiment of the present invention; Figure 3 This is a schematic diagram illustrating the structure of a steel reed fixture according to an embodiment of the present invention; Figure 4 This is a schematic diagram illustrating the cross-sectional structure of a steel reed fixture according to an embodiment of the present invention; Figure 5 This is a schematic diagram illustrating the structure of a monofilament printing mesh according to an embodiment of the present invention. Please refer to... Figures 1 to 5 In one embodiment of the present invention, the method for manufacturing monofilament printing mesh includes steps S101-S107. Step S101 involves stretching multiple yarns 10 and straightening them. Step S103 involves passing the straightened yarns 10 through a reed 20 to perform a first-stage spacing adjustment. The reed 20 is a reed fixture with holes. After the yarns 10 pass through the reed 20, the first-stage spacing adjustment can be performed, allowing the yarns 10 to be initially arranged. However, because the reed 20 is an elastic reed fixture that can be used for weaving on a loom, it is impossible to perform fine and uniform spacing adjustment of the yarns 10, especially under conditions of fine filament diameter and high mesh count. Therefore, the present invention specifically uses step S105 to perform a second-stage fine spacing adjustment.

[0048] Step S105 involves passing the yarn 10 through the reed 20 through a reed fixture 30 for a second-stage spacing adjustment. Specifically, the reed fixture 30 includes multiple guide grooves 301, through which each yarn 10 can pass for the second-stage spacing adjustment. Furthermore, in one embodiment of the invention, the yarn 10 has a diameter d, the guide grooves 301 have a width W and a depth D, and the guide grooves 301 are spaced apart by a distance L. The width W, depth D, number, and distance L of the guide grooves 301 can be adjusted according to the yarn diameter d, quantity, and set distance between the yarns 10 to provide the optimal second-stage spacing adjustment effect.

[0049] In addition, although Figure 3 The image shows a flat reed fixture 30, but it can also be changed to a cylindrical reed fixture 30 or other shapes of reed fixture 30 to adapt to various different process operations.

[0050] Finally, step S107 is performed: the yarn 10 passed through the reed fixture 30 is pressed together with a polymer material film layer 40 to form a monofilament printing mesh fabric 60. In the structure of the monofilament printing mesh fabric 60, all yarns 10 extend in the same direction and are parallel to each other, thus creating a monofilament mesh fabric that does not produce warp and weft yarn cross-knots. Furthermore, the polymer material film layer 40 can be one of terephthaloline, PET, PE, PI, PU, ​​PVC, PP, PTFE, PMMA, PS, or other polymer materials. Moreover, the pressing method between the yarn 10 and the polymer material film layer 40 can be hot pressing, physical pressing via a pressing device 50, or other pressing methods.

[0051] Figure 6 This is a schematic diagram illustrating the structure of a monofilament printing screen according to an embodiment of the present invention. Figure 7 This is a schematic diagram used to illustrate. Figure 6 The AA section structure is shown in the image. Please refer to... Figure 6 and Figure 7 In one embodiment of the present invention, a monofilament printing screen is provided. The monofilament printing screen includes a frame 70, a monofilament printing mesh 60 manufactured using the above-described manufacturing method of the present invention, and at least one opening pattern 80. The monofilament printing mesh 60 is fixed to the frame 70 and includes a squeegee surface S10 and a printing surface S20. It is worth noting that because the opening pattern 80 is formed on the monofilament printing mesh 60, the opening pattern 80 only includes one type of yarn 10. In the present invention, it is not necessary to use other processes to remove other yarns from the monofilament printing mesh 60, thus avoiding the problem of uneven rolling marks on one type of yarn after removing other yarns, as is present in the prior art. Simultaneously, because the monofilament printing mesh 60 is composed of a single yarn 10, the yarn 10 in the opening pattern 80 is a flat yarn, unlike the wavy pattern formed by two types of yarns interwoven in the prior art. The flat yarn 10 prevents ink from being stuck during printing.

[0052] In this way, after the ink falls from the squeegee surface S10, it can flow smoothly from the printing surface S20 without any obstruction, resulting in a more complete and conductive image and improved printing yield. Furthermore, in one embodiment of the invention, the yarn 10 can be non-woven fabric or commonly used yarn material; in other embodiments of the invention, to improve the durability of the monofilament printing screen, the yarn 10 can be made of metal.

[0053] Figure 8 This is a schematic diagram illustrating the structure of a monofilament printing screen according to another embodiment of the present invention; Figure 9 This is a schematic diagram used to illustrate. Figure 8 The A'-A' cross-sectional structure in [the image / image]. Please refer to [the image / image]. Figure 8 and Figure 9 In another embodiment of the invention, a different monofilament printing screen is provided, which is consistent with... Figure 6 and Figure 7 The structural difference between the monofilament printing screens shown lies in the different weaving directions of the yarns 10 in the monofilament printing mesh 60. Figure 6 The yarn 10 shown is woven in the weft direction. Figure 8 The yarn 10 shown is warp-woven, and similarly, the warp-woven yarn 10 can be made of non-woven fabric or commonly used yarn materials. In other embodiments of the invention, to improve the durability of the monofilament printing screen, the warp-woven yarn 10 can be made of metal. It is worth noting that in this embodiment, the opening pattern 80 can be positioned between two adjacent yarns 10 to completely avoid the yarn 10 within the opening pattern 80. In other embodiments of the invention, the opening pattern 80 may include the yarn 10 (not shown in the figures). Similarly, because the yarn 10 is a flat thread, ink jamming during printing can be avoided.

[0054] In other words, the yarns 10 in the monofilament printing mesh 60 of the present invention can be woven in the weft or warp direction. Regardless of whether it is woven in the weft or warp direction, the opening pattern 80 will not include any warp and weft yarn cross knots or simultaneously include warp and weft yarns, and there is no need to use other processes to remove other yarns. In this way, when the ink falls from the squeegee surface S10, it can flow smoothly from the printing surface S20 without any obstruction, and print more complete graphics with better conductivity and improve printing yield.

[0055] Figure 10 This is a schematic diagram illustrating the structure of a monofilament printing composite screen according to another embodiment of the present invention. Please refer to... Figure 10 In another embodiment of the present invention, a monofilament printing composite screen is provided. This screen includes a frame 70, a first material mesh 90, a monofilament printing mesh fabric 60 manufactured using the method described above, and at least one opening pattern 80. The first material mesh 90 is fixed to the frame 70 and can be one of a polyester mesh fabric, a polymer film mesh fabric, a metal mesh fabric, or a composite mesh fabric combining multiple of these mesh fabrics. The monofilament printing mesh fabric 60 is fixed to the first material mesh 90 and also includes a squeegee surface and a printing surface. The opening pattern 80 is formed on the monofilament printing mesh fabric 60. In this embodiment, the first material mesh 90 and the monofilament printing mesh fabric 60 are combined, thus reducing the area of ​​the monofilament printing mesh fabric 60 and lowering the manufacturing cost of the monofilament printing composite screen. Since the monofilament printing composite screen also uses the monofilament printing mesh fabric 60, it simultaneously possesses the advantages of the monofilament printing mesh fabric described above. It should be understood that, although Figure 10The image shows a weft-woven yarn 10, but the yarn 10 can also be warp-woven, and the weft- or warp-woven yarn 10 can be non-woven fabric, commonly used yarn material, or metal material.

[0056] As can be seen from the above description of the present invention, the present invention provides a method for manufacturing monofilament printing mesh, a monofilament printing screen, and a monofilament printing composite screen. The method for manufacturing monofilament printing mesh, the monofilament printing screen, and the monofilament printing composite screen of the present invention have the following effects and advantages: 1. A two-stage positioning method is used to adjust the spacing between the yarns, which can effectively obtain the required yarn spacing. 2. The yarns with the adjusted spacing are directly pressed with a polymer material film layer, so that the monofilament printing mesh can be obtained quickly and simply. 3. The monofilament printing mesh is further processed into a monofilament printing screen, and at least one open pattern is set on the monofilament printing mesh. In this way, the open pattern will not include any warp and weft yarn cross knots, and there is no need to use other processes to remove other yarns, and more complete graphics with better conductivity are printed, and the printing yield is improved.
