Description of the Related Art Textile printing is a method of fixing various patterns on a printing material such as cloth by using a screen printing plate or the like with an ink made of a pigment and a binder. In order to give a gold color, flake brass powder (a flake copper-zinc alloy powder generally called gold powder or bronze powder, hereinafter referred to as gold powder) is mixed with an aqueous binder such as an acrylic emulsion. Inks are often used.

If the eyes are clogged, not only can the desired picture not be printed, but printing must be interrupted and the plate washed. Rotary screen printing has drawbacks such as reduced productivity. When the particle size of the gold powder used is reduced, the screen printability is improved, but the golden luster is deteriorated, and with a thin cloth, a show-through phenomenon in which the gold powder particles pass to the back side is caused to cause stain. In the method of increasing the mesh size of the screen printing plate until it is not clogged, a fine pattern cannot be printed, and only a product having a low commercial value can be obtained.

明を完成したものである。SUMMARY OF THE INVENTION The present inventors have studied the relationship between screen printability and the average particle size of gold powder, particle size distribution, shape of gold powder, and golden gloss after printing. Instead, by setting the relationship between the specific surface area and the average particle size to an appropriate value, clogging of the screen printing plate can be prevented, fine patterns can be printed, golden metallic luster is good, and even a thin cloth can be used. Various experiments have confirmed that a printing gold powder that does not cause a reflection phenomenon can be obtained, and the present invention has been completed.

ET method specific surface area value (Ycm 2 / g) is 4400-20A
≦ Y ≦ 6400-40A, and the remaining amount on a 75 μm sieve is 1% or less. The reason why the average particle diameter is limited to 30 to 50 μm is that if the average particle diameter is smaller than 30 μm, even if the specific surface area value of the present invention is satisfied, excellent golden luster cannot be obtained and gold powder particles may pass through to the back side of the cloth. . If the average particle size is larger than 50 μm, clogging is increased in rotary screen printing even if the specific surface area value of the present invention is satisfied, and printing of details becomes difficult. The average particle size of the gold powder is a measured value of the average particle size by a laser diffraction measuring apparatus. The gold powder for printing of the present invention is required to have a residual amount on a sieve of 75 μm of 1% or less, as measured by a particle size distribution measurement method using a sieving method. When 1% or more of coarse powder of 75 μm or more is contained, the screen printing plate is clogged during printing even if the average particle size is small.

定装置による測定値である。An important point of the present invention is that the BET specific surface area of the gold powder satisfies the claims corresponding to the average particle size. That is, when the average particle diameter is A μm, the specific surface area value Ycm 2 / g of the gold powder by the BET method is 4400-20A ≦ Y ≦ 640.
It needs to be 0-40A. When the BET specific surface area value of the gold powder having an average particle size of A μm is smaller than 4400-20A, the gold powder is a thick rounded flake powder, the gold powder is easily peeled from the cloth, the golden gloss is poor, and the concealment is poor. Since the force is very poor, a uniform golden printing surface cannot be obtained unless a large amount of gold powder is mixed into the binder. When the BET specific surface area value is larger than 6400-40A, the gold powder often contains a large amount of fine powder. Generally, gold powder is a production method in which a large metal lump is mechanically pulverized finely. Therefore, when the BET specific surface area value is larger than the average particle size, the powder contains a large amount of fine powder.
When gold powder containing a large amount of fine powder is used for printing, the golden luster is poor due to the influence of the fine powder, and the fine powder causes show-through of the cloth, causing stains. It is difficult to define the particle size distribution state of the gold powder, the amount of the fine powder, and the shape of the gold powder. In the present invention, the gold powder for printing is specified based on the relationship between the average particle diameter and the BET specific surface area. The BET specific surface area value is a value measured by a BET specific surface area measuring device that adsorbs an inert gas.

粉を得る。As a method for producing the gold powder for printing of the present invention, a method of classifying commercially available gold powder. Gold powder generally sold is mainly used for paints, and has a large amount of fine powder and a large specific surface area in order to obtain hiding power. Therefore, the fine powder in the gold powder is removed using an air classifier to obtain a gold powder for printing that satisfies the conditions of the present invention. A method to spread flaky powder. Thick flaky powder having an average particle size of 50 μm or more is used as a starting material, placed in a ball mill or the like together with steel balls, a small amount of fat is added, and the powder is slowly spread so that fine powder is not generated. Get. A method of pulverizing fine granular powder. If the starting material is large, pulverization to the desired particle size will generate a lot of fine powder. Therefore, using as fine a granular powder as a starting material, flake processing is performed with a pulverizer such as a ball mill and an agitator mill while adding a small amount of fats and oils to obtain the gold powder for printing of the present invention.

９７号などの処理をすることも可能である。As long as the average particle size and the specific surface area are within the range of the present invention, it can be used as gold powder for printing, but the production method most suitable for screen printability is the following method. The gold powder obtained by the above method has a rounded shape at the end of the gold powder, so that it is hard to catch the eyes of the screen and the printability is further improved.
The method for reducing the residual amount on the sieve of 75 μm or more to 1% or less is 200
What is necessary is just to remove coarse powder using a mesh sieve. Since the gold powder for printing of the present invention has a small amount of fine powder and a narrow particle size distribution, it can be uniformly dispersed as it is in a printing binder. To prevent the scattering of powder, the printing gold powder of the present invention is disclosed in Japanese Patent No. 26386.
It is also possible to carry out processing such as No. 97.

に多くの金粉の残留が認められた。Comparative Example 1 Commercially available gold powder having an average particle size of 45 μm and a specific surface area of 7500 cm 2 / g by the BET method used in Example 3 was sieved with a 200-mesh sieve to give a thickness of 75 μm.
The remaining 5% on the sieve was removed. As a result, the average particle size was 42 μm.
m, a gold powder having a BET specific surface area of 7,800 cm 2 / g was obtained. 30 parts by weight of this gold powder was mixed with 70 parts by weight of an acrylic emulsion printing binder with a mixer,
A gold ink was prepared. Using a screen printing plate of 150 mesh, the prepared gold ink was printed on a cloth with a line having a width of 1 to 5 mm and a length of 3, and after natural drying, the gold printed portion was observed. As a result, the fine line portion was printed uniformly, but was inferior in metallic luster. Further, the fine powder passed to the back of the cloth and soiled the lower fixing rubber plate, and was difficult to use for printing. In addition, the fluidity of the gold ink mixed with the binder for textile printing was poor and the printability was poor, and a large amount of gold powder remained on the screen printing screen net after printing.

汚れもなく金色捺染が容易に出来るようになった。In recent years, in order to give a high-quality feel to a cloth such as a duvet, there have been an increase in the number of patterns subjected to golden printing. However, the conventional gold powder often causes clogging of the screen printing plate, and it is necessary to stop the machine during the printing and wash the plate. This was a serious drawback especially in rotary screen printing which prints in large quantities and at high speed. However, if the printing gold powder of the present invention is used, clogging of the screen printing plate does not occur even when printing is performed in a large amount, the golden metallic luster is also improved, and there is no stain due to show-through of the cloth, and the golden printing is performed. Can be easily done.
