Description

  The present invention relates to an advertising medium having flameproofness. More specifically, the present invention relates to an advertising medium such as a curtain, a flag, and a cocoon made of a fabric having flame resistance without using a halogen-based flame retardant and having a clear and durable pattern / pattern.

  Curtains, flags, and banners are often used as advertising media in stores and special events. Patterns and patterns such as characters and images are formed on a fabric made of fibers using various printing techniques. Fabrics made of fibers are basically combustible, but for reasons of disaster prevention, these advertising media are also required to have flame resistance.

  Examples of a method for imparting flame resistance to the fabric include a method using non-combustible fibers such as aramid or a synthetic fiber kneaded with a flame retardant. However, the method using these special fibers is not preferable because the cost is high in an advertising medium having a short replacement cycle.

  Patent Document 1 discloses a flameproof processing method in which a pattern or the like is printed with a pigment printing dye paste obtained by mixing a flameproofing agent in a synthetic resin emulsion and then dried, and then the flameproofing agent is attached to the entire surface of at least one side of the fabric. Is disclosed. In this method, the color reproducibility is good, the texture is soft, and sufficient flameproof performance can be easily imparted. However, there are two processes: a process of printing a pattern and the like and a process of attaching a flameproofing agent to the entire surface of one side of the fabric. A process is required.

  In Patent Document 2, a flameproof agent is permeated and fixed on a polyester fabric, and silk printing is performed on the obtained fabric using a flameproof pigment ink, or a sublimation type disperse dye is printed by ink jet printing. Is disclosed. This method also requires two steps, and in the former silk printing with the flameproof pigment ink, there is a possibility that a problem occurs in the durability of the pattern because the flameproof pigment ink is superimposed on the flameproofing agent that has been fixed by penetration. is there. Most of these advertising media are used outdoors, and strong stagnation is always applied by flapping depending on the wind. The partially laminated pattern portion (flameproof pigment ink portion) is weak against stagnation and inferior in durability. In the latter method of printing with a sublimation type disperse dye, it is dyed through a layer of a flameproofing agent that is permeated and fixed to the fabric, and the pattern is not clear.

  In addition, flameproofing agents containing halogen elements with high flameproofing effects have been used in the past, but those containing these halogen elements are likely to affect the human body and the environment, so it is necessary to refrain from using them. It is becoming.

Japanese Patent Laid-Open No. 11-1870 JP 2007-193002 A

  The present invention provides an advertising medium having flameproofness that solves the problems of the conventional techniques. In other words, an advertisement medium that can be manufactured by a simple process and has a flameproof property that does not contain a halogen element.

The first aspect of the present invention has a pattern portion formed by using a first ink containing a flameproofing agent not containing a halogen element and a binder on a base material made of only a fiber fabric. The ink has a different optical characteristic and has a base portion formed by using a second ink containing a flameproofing agent not containing a halogen element and a binder, both of which are acrylic resin and urethane An advertisement medium comprising a resin and having a urethane resin solid content to acrylic resin solid content weight ratio of 0.25 to 1.

  It is preferable that a pigment is contained in one or both of the first ink and the second ink. The fiber fabric is preferably made of polyester fiber.

Furthermore, the present invention secondly, a step of printing a pattern portion on a substrate made of only a fiber fabric using a first ink containing a flameproofing agent not containing a halogen element and a binder, and the first ink And a step of printing a base portion on a substrate made of only a fiber fabric using a second ink containing a flameproofing agent that does not contain a halogen element and a binder. Is a method for producing an advertising medium, characterized in that both contain an acrylic resin and a urethane resin, and the weight ratio of the urethane resin solids to the acrylic resin solids is 0.25 to 1.

  ADVANTAGE OF THE INVENTION According to this invention, the advertisement medium which has flameproofness can be provided with a simple process, This advertisement medium does not contain a halogen element.

  The advertising medium of the present invention is based on a fabric made of fibers. Although it does not specifically limit as a fiber, A synthetic fiber is preferable from viewpoints, such as intensity | strength, Furthermore, a polyester fiber is preferable from a viewpoint of a weather resistance. Examples of the fabric made of these fiber materials include woven fabric, knitted fabric, and nonwoven fabric. The fabric used as the base material may be subjected to normal fiber processing such as scouring, setting, and dyeing in advance.

  The ink used in the present invention contains an acrylic resin and a urethane resin as a binder. The weight ratio of the urethane resin solid content to the acrylic resin solid content is 0.25 to 1.

  The acrylic resin and the urethane resin as the binder have a function of fixing the flameproofing agent and the pigment to the fabric surface. Acrylic resins are generally flammable and tend to reduce the effect of flame retardants used in combination, but they are excellent in the effect of stably dispersing flame retardants and pigments in the ink, and the film forming speed is slow, so continuous processing Suitable for. On the other hand, the urethane resin has poor ink stability, and the film forming speed is too high to be suitable for continuous processing, but it itself has the property of being difficult to burn.

  By containing these two types of resins as binders in a range where the weight ratio of the urethane resin solid content to the acrylic resin solid content is 0.25 to 1, high flameproofness is imparted, ink stability, and continuous processing An appropriate ink can be obtained. If the weight ratio is less than 0.25, sufficient flameproofness cannot be obtained. When the weight ratio exceeds 1, the stability of the ink is deteriorated and the continuous processability is lowered.

  The flameproofing agent is required not to contain a halogen element. Examples of such a flameproofing agent include phosphorus-based flameproofing agents, and the combined use of ammonium polyphosphate and a phosphate ester is particularly preferable.

  As the pigment, an inorganic pigment, an organic pigment, or the like can be used without particular limitation. The pigment may be contained only in one of the first ink and the second ink, or may be contained in both inks.

  In general printing, colored ink is applied to the pattern portion, and the pattern or pattern is expressed by a color difference from the base portion. Usually, the fabric itself is exposed without applying any ink to the base portion. In this case, since no ink is applied to the base portion, naturally no flameproofing agent is applied. Therefore, when the area of the handle portion is small, sufficient flameproofness cannot be obtained as the entire advertising medium. Therefore, in the present invention, the second ink containing the flameproofing agent and the binder is also applied to the base portion, and as a result, the ink is applied to all at least one surface of the fabric.

  In order to form a handle or a pattern, a difference in optical characteristics is required between the handle portion and the base portion. Either one of the first ink and the second ink may contain a pigment, or the pigment contained in each ink may have a different color. The same color may have a difference in density, or an arbitrary additive may be added to design a difference in gloss. Further, the first ink forming the pattern portion may be only one type (one color) or a plurality of types having different colors. When printing, a plurality of inks may be applied so as to overlap each other. Even in such a case, the inks are easily mixed with each other before being dried or cured, and the layer structure is not formed. Since the layer structure is not formed, a handle having sufficient durability against stagnation can be obtained.

  The advertising medium of the present invention is formed by printing a pattern / pattern on the fabric surface using the ink. Examples of the printing method include screen printing, rotary printing, and ink jet printing.

After a pattern / pattern is printed using the above ink, the fabric may be dried for the purpose of volatilizing the solvent in the ink. Moreover, when the used binder is bridge | crosslinked by heat processing, you may cure on the conditions which raise | generate a crosslinking reaction. These are appropriately performed depending on the characteristics of the solvent in the ink and the characteristics of the resin.

(Create ink)
Each ink was prepared with the blending amounts shown in Table 1. In each of the examples and comparative examples, a first ink for a pattern portion (containing DEXEL RED-HB as a pigment) and a second ink for a base portion (containing Super White MC-108 as a pigment) were prepared. A 100% polyester Ponji fabric (weight per unit: 62 g / m ² ) with each ink and printing plate using an automatic printing machine, a predetermined pattern is formed into a base part (second ink), a pattern part (first ink) Were printed in this order and dried with hot air of 150 ° C. for 1 minute to obtain an advertising medium. At this time, the amount of ink applied was 60 g / m ² .

The obtained advertising media were subjected to a flameproof performance test based on firefighting laws. The evaluation criteria for thin cloth sheets and curtains are the initial and after immersion in warm water, with the 45 ° microburner method, heating for 1 minute and heating for 3 seconds after flaming, residual flame time of 3 seconds or less, residual dust The time is 5 seconds or less, the carbonized area is 30 cm ² or less, and the number of flame contacts is 3 or more in the 45 ° coil method. The pass / fail result of each test is shown in Table 1.

  Concerning continuous processability, pass / fail judgment was made by observing the print quality (scratch, color loss, etc.) of the advertising medium and clogging of the printing plate when 1000 m was printed, and the results are shown in Table 1.
