Description

  The present invention relates to a flag manufacturing method and a flag.

When processing functional drugs on polyester fabric (tropical), which has been used in banners and hanging banners that have been used throughout the country, the weight is relatively high. Screen print the design and dry. Next, a method in which a functional drug is applied to the entire front and back surfaces of the product by a method such as dipping (immersion) is used.
Japanese Patent Laid-Open No. 11-1871

  However, the above technique has a problem in terms of design quality. Certainly, functional drugs (for example, flame retardants) are improved by dipping, but since the drugs are not uniformly applied to the design surface by dipping, white unevenness occurs in the image and the quality of the design deteriorates. With the recent development of image processing technology, the demand for the color quality of the printed surface is increasing, and it is difficult to further spread products with functional drugs for tropical fabrics unless the quality problem is overcome.

  Therefore, an object of the present invention is to realize printing that maintains image quality and retains functional drug performance.

  In order to solve the above-mentioned problems, the present invention is characterized in that a halftone pattern is used when printing a functional medicine on the back side after printing advertisement contents on the front side of the flag.

  According to the present invention, when the functional agent is fixed to the back surface by silk screen printing and rotary screen printing, a halftone dot pattern is used as a plate to be used. Thereby, a functional chemical | medical agent can be fixed to the back surface upper part of cloth | dough, and it can prevent that a color loss is carried out to the surface design surface. Therefore, when a desired design is printed on one side of the flag and a functional drug is fixed on the other side, a method for manufacturing the flag is provided to prevent the color of the other side from falling out on the one side. The Rukoto.

  The flag according to the embodiment of the present invention includes a first step of printing a desired design on one side of a fiber cloth fabric, and a second step of fixing a functional agent on the other side of the fiber fabric fabric. Manufactured through a process. At that time, a net pattern is used in the second step.

  Here, functions include, for example, flame resistance, flame retardancy, photocatalytic effect, water repellency, oil repellency, deodorization, antibacterial / antibacterial, antiseptic, antifungal, ultraviolet absorption / shielding, absorption / release Includes moisture, negative ion generation, waterproofness, water absorption, oil absorption, yellowing resistance, poor melting, aromaticity, moisture permeability, water permeability, humidity control, antistatic properties, antifouling properties, conductivity, The kind is not particularly limited. A functional drug is a drug that can achieve the above functions. If it is flameproof, it will function as a flameproof drug, and if it has a photocatalytic effect, it will have a photocatalyst (such as titanium oxide). It refers to drugs that can be used.

  Here, the flag is a promotional flag, banner, banner, company flag, school flag, championship flag, national flag, party flag, team flag, labor flag, hand flag, cheer flag, signal flag, safety flag, safety Sanitary flag, ship flag, devout flag, shrine flag, gate curtain, float curtain, crest curtain, mud curtain, cheer curtain, water curtain, stage curtain, bonfire, see-off curtain, shrine fence, sumo wharf, samurai fence, samurai, It refers to all flags such as Momotaro, Back, Actor (Kabuki), Tapestry, Banner.

  The fiber cloth fabric is a cloth fabric woven with fibers. Examples of the fiber cloth cloth include a cloth cloth woven with chemical fibers and a cloth cloth woven with natural fibers. As cloth fabrics woven with chemical fibers, fabrics called Ponzi and Tropical are often used in promotional banners. Ponzi refers to a fabric in which warp and weft yarns are each woven at 75 denier. Tropical refers to a woven fabric in which warp and weft yarns are each woven at 150 denier. In addition, the fiber cloth fabric used in the present invention is not limited to a synthetic fabric, a natural fabric, a pongy or a tropical fabric.

  The surface on which the desired design is printed may be either side of the fiber cloth fabric. Silk screen printing is used in the process of printing the desired design on one side and the functional drug on the other side. The main printing methods include gravure printing using intaglio, offset printing using flat plate, relief printing using letterpress, screen printing using stencil and the like. In silk-screen printing used in the present invention, a fiber cloth fabric, which is a printed matter, is placed under the plate using a plate called an stencil through which an image portion passes. Color glue is put on one end of the screen plate, and the squeegee is moved back and forth to extrude the color glue under the ridge of the screen for printing.

  Here, the screen plate making method will be described. First, a stencil is put on the plate frame and the emulsion is coated. A document (transparent positive type) is pasted, exposed with a mercury lamp, and then developed. The portion that is not exposed by washing with water becomes a stencil and becomes a transfer portion of the color paste. Recently, the design original is not a transparent positive, but a direct plate making method using an ink jet printer is also used.

  There are wood, aluminum, stainless steel, plastic, etc. for the screen frame, but the aluminum material is overwhelmingly large considering the processing method, light weight and cost.

  There are silk, nylon, tetron, and stainless steel as the material for the cocoons, but Tetron cocoons are used relatively frequently. Screen printing is still called silk screen because it was used as the most suitable thread material before the emergence of thread materials such as nylon, tetron, and stainless steel. Remains. In addition, there are various types of meshes, and when fine expressions are generally required, a high mesh (180 to 200) is used, and a low mesh (135) is used for a solid version such as a special color.

  In one embodiment, after printing a desired design on one side and printing a functional agent on the other side, the plate mesh used may be a high mesh. 200 mesh is more preferable.

  In one embodiment, the halftone dot pattern prints an amount that can guarantee the performance of the functional drug and that the functional drug does not lose its color so as not to impair the design quality. A lattice-like pattern similar to a halftone dot may be used so that it can be realized.

  As an embodiment, the number of halftone dot screen lines in expressing a halftone dot pattern is preferably between 35 and 45 lines. Moreover, 45 lines are better.

  As one embodiment, the halftone dot density is preferably in the range of 50% to 70% with 100% solid. More preferably, 70% is good.

  As an embodiment, the halftone dot pattern plate may use the above 70% halftone dot pattern plate only at both ends of the plate, and the other portion may use a 100% solid plate.

  In one embodiment, after printing a desired design on one side and printing a functional agent on the other side, the method may use a rotary screen machine.

  In order to bring about a functional drug effect by combining these various conditions, it is possible to print so as not to lose color up to the design surface while fixing as many agents as possible to the fiber surface.

  Examples of the present invention are shown below, but the present invention is not limited to these Examples.

This is an example in which a flameproof chemical is used as a functional chemical on a tropical fabric (weighing 100 g / m ² ) woven with 150 denier warp and weft as a fiber fabric, and a flag with flameproof performance is produced.

  First step: A desired design was printed on the surface of the fiber cloth fabric by silk screen printing and dried. In addition, a flameproofing agent is mixed in the color paste printed on each plate. Specifically, the color paste is a mixed liquid of a flameproofing agent (Daicel Ink Chemical Industries, Ltd .: Dexcel Clear FR-813NE) and ink paint. In the color paste of each color, the concentration of the ink paint is within 10%.

  Second step: A flameproofing agent (Daicel Ink Chemical Industries, Ltd .: Dexcel Clear FR-813NE) was printed on the back side of the fabric fabric using a silk screen and dried. A halftone dot pattern is used as the plate used here. The specification of the version is that the wrinkles used are 200 mesh. The number of screen lines is expressed by 45 lines. When the entire surface is 100%, a density of 70% is expressed by a halftone dot pattern.

The processed fabric was subjected to a flameproof performance test based on firefighting laws. The test results are as shown in Table 1. In the case of 45 degree micro burner method, the evaluation criteria for sheets and curtains are 1 minute heating and 3 seconds heating after flame, after flame time 3 seconds or less, and residual dust time 5 seconds. Hereinafter, the carbonized area is 30 cm ² or less.

  As shown in Table 1, in each of Examples A and B having different surface designs, the level of passing the flameproof test was satisfied. Moreover, the flameproof chemical | medical agent was not missing with respect to the desired design surface, and the printing by which the required design quality was hold | maintained was performed.

  The method for producing a flag according to the present invention is capable of preventing omission of the color of the back surface when the functional drug is adhered to the back surface, and stabilizing the functional drug performance (flameproof, photocatalyst, etc.). It is useful in the field of manufacturing various flags.
