Description

[Detailed Description of the Invention] The present invention is a labor-saving process for hand-carving patterns for Japanese clothing, etc., and significantly reduces the number of manufacturing steps required for drying, etc. in the past. This article relates to a method for creating paper patterns that greatly reduces time.

Conventionally, a photo-engraving method has been introduced for the purpose of streamlining the production of Japanese clothing patterns and the like. However, in order to finish one piece of Japanese clothing, it costs 300 to 600 yen for one piece of high-class clothing.
Since a 0 pattern is required, a large number of 9 editions are required, which not only increases costs, but also makes it difficult to store the patterns. Therefore, the hand-carved method, which requires fewer patterns, is the most popular method for making paper patterns.

Regarding the paper pattern sheet body used in this hand carving method.

In order to meet these requirements, strength, dimensional stability, punchability during engraving (cutting ability), water resistance, etc. are required.

Utility Model Publication No. 58-6703, Utility Model Publication No. 55-511, and Utility Model Number 54-19427.

Special Publication No. 50-40190 and many other proposals have been made.

However, these proposals merely improve the pattern mill, and do not lead to significant labor savings in pattern creation, and this hand carving method not only requires a large number of steps.

The present invention has succeeded in greatly streamlining the process of making paper patterns, which still requires a very delicate and troublesome engraving process. The present invention will be explained in detail below.

In the present invention, the method of transferring the original image to the paper pattern is carried out by the same means as the conventional method, but the most suitable paper pattern to be used is 11.
As shown in the figure, the surface of the base material sheet 1, such as a cloth made of polyester fiber with good dimensional stability, 2 non-woven fabrics, etc., is bonded to the Tetron gauze to be bonded in the #& process, and in a separate post-process. In order to prevent the solvent of the top coat used from penetrating, a coating layer 2 of 5 μm or less of saturated polyester resin is provided, and in order to prevent dye leakage, a coating layer 2 of 3 μm to 20 μm thick is provided on the back side to prevent dye leakage.
A coating layer 3 of μ nitrified cotton paint is used.

This paper pattern is then glued to a mount.The mount used in the present invention is made of commercially available thick paper with a thickness of 1.5 to 31 mm, as shown in FIG. A rubber adhesive 1-5 is provided, and the pattern is placed on this mount and heated in a heat press at a temperature of 80 to 110°C and a pressure of 0.
．． Temporarily adhere the mount and pattern paper under the conditions of 3 to 5 kg/h for 1 hour and 7 to 30 seconds.

The mount is indispensable not only to prevent shrinkage during various processing, but also to maintain the pattern as it is when punched out without leaving hanging marks during hand carving, which is the third feature of the present invention. Moreover, this mount can be peeled off after use and used over and over again. The solvent-type synthetic resin rubber adhesive used for the adhesive layer on this mount includes styrene-butadiene copolymer, acrylic acid-butadiene copolymer, acrylonitrile-butadiene copolymer, and other commonly used adhesives. Can be used.

However, water-soluble resin (emulsion type) adhesives have drawbacks such as curling of the mount and are difficult to use, and adhesive type adhesives have problems with workability.

When manually engraving a pattern that has been temporarily glued to the mount, there are cases where the pattern inside is missing using the conventional method (for example, Fig. 3A).
When cutting out the pattern 7 in the shaded area from the paper pattern 6 as shown in Figure 3B), in order to leave the pattern 8 inside, it was necessary to leave the hanging 9 as shown in Figure 3B. Hanging 9
There is no need to leave any hanging marks, and you can simply carve and punch out the pattern as shown in Figure 3 A, which greatly improves the efficiency of hand carving work, especially in the case of rough patterns, and also avoids leaving hanging marks inadvertently. Mistakes like this can also be prevented.

Tetron gauze is then applied. In order to strengthen the adhesive force with the surface of the paper pattern layer, Tetron gauze can be used as is, but the Tetron gauze used may be pre-impregnated with a polyester adhesive or the pattern paper and Tetron gauze may be pasted. It is more preferable to carry out a process such as sandwiching a hot-melt resin film with strong adhesive strength between the paper pattern and the gauze, followed by hot pressing. It is sufficient that the heat press conditions are the same as those used for temporarily adhering the mount and pattern paper.

Next, after peeling off the temporarily attached mount from the paper pattern, the surface of the paper pattern is coated with synthetic lacquer once or twice in the same manner as in the past, and the paper pattern is completed. When the peeled mount is repeatedly used and its adhesive strength decreases, it is preferable to increase the adhesive strength by applying a solvent-type synthetic rubber adhesive to the surface of the mount using a printing press or the like.

To further illustrate the differences between the present invention and the conventional method, the main parts are as follows: The conventional process is shown in Figure 4A;
As shown in Figure B, the conventional method is to first transfer the original image onto a paper pattern, then carve it so as to leave a hanging part, apply adhesive such as glue to the washi paper, back the paper pattern, and then dry. After drying, remove the hanger, apply an adhesive with good adhesion to Tetron, attach Tetron gauze, and let the adhesive dry. Furthermore, it required a step of overcoating the surface with synthetic lacquer and drying it again to complete it, so compared to the present invention, there were more drying steps, and the hand carving was extremely complicated. . That is, in the present invention, there is no need to leave a hanging during hand carving. 0 There is no need to back the product with difficult-to-handle Japanese paper after hand carving, so the work is simple and the long drying time is completely unnecessary. ■The undercoating and drying for pasting the gauze are omitted. ■No lifting work required.

The present invention has advantages such as, and the effect is very large just by installing a heat press machine at the beginning.
