Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a method for forming multicolored thick-walled patterns on base materials such as nonwoven fabric, felt, synthetic leather, and thermoplastic resin sheets using one intaglio plate and one heating process. -Relates to a method for forming a multicolor thick pattern using a pressurizing operation.

[Prior art field of the invention and its problems] One-point marks or patches (image-formed Paj with a thick pattern) are attached to sportswear, bags, etc. for the purpose of advertising the company's products or showing off famous affiliated brands. There is. Traditionally, these are embroidered.

It is created by welding, flocking transfer, heat transfer, etc., but it cannot be expected to form a thick pattern with a rich three-dimensional effect by any of these methods. On the other hand, there has been a recent trend toward favoring multicolored one-point marks and patches that have a rich three-dimensional effect, and there is a strong desire to develop a method for forming multicolored thick patterns that have a rich three-dimensional effect. Under these circumstances, a method for forming a multicolored thick pattern with a rich three-dimensional effect is to fill all the recesses of the intaglio with a thermoplastic resin colored in the desired color, and then fill the desired recesses with the thermoplastic resin. The process of first removing the thermoplastic resin and then filling only the unfilled recesses with thermoplastic resin colored in another color is repeated a desired number of times, thereby coloring the desired recesses of the intaglio plate in the desired color. After filling the recessed thermoplastic resin, the base material is placed on top of the plate surface of the intaglio plate, heated and pressurized to transfer and fix the thermoplastic resin filled in the recesses to the base material surface, and then cooled and then placed on the base material. Peel the material from the intaglio plate surface.

A method for forming a multicolor thick pattern, characterized by forming a desired multicolor thick pattern on a base material (Japanese Patent Application No. 106587/1987)
' has been proposed. Although this method is an excellent method for forming extremely three-dimensional multicolored thick-walled patterns made of thermoplastic resin, it cannot be applied to the formation of multicolored thick-walled patterns made of thermosetting resin.

On the other hand, silicone rubber is attracting attention as a material for forming multicolor thick patterns because of its excellent heat melting properties, weather resistance, solvent resistance, oil resistance, etc. However, silicone rubber is hardened by heating and then heated again.
It is not possible to employ the process of softening and melting the material and applying heat-pressing to bring it into close contact with the base material. Therefore, it is not possible to form a multicolor thick pattern using the above-mentioned method for forming a multicolor thick wall pattern. When forming a multicolor thick pattern made of silicone rubber on a base material using an intaglio plate having recesses for forming a multicolor thick pattern, the silicone rubber filled in the recesses is transferred to the four base materials. It must be left uncured until then. Therefore, in order to form a multicolor thick pattern made of silicone rubber on a substrate by using an intaglio plate having recesses for forming a multicolor thick pattern and silicone rubber, a quantitative dispenser is used to obtain the desired color. Selectively distribute colored uncured silicone rubber only to desired recesses, or apply uncured silicone rubber colored only to desired recesses while sequentially masking recesses where you do not want silicone rubber to enter. A sequential filling method, etc. must be adopted.

However, in these methods, if the patterns are fine and close together, it becomes difficult to fill with silicone rubber, and the efficiency is extremely poor (which makes them undesirable as methods for forming good multicolor thick patterns in large quantities). do not have.

[Purpose of the invention]

The present invention was developed as a result of intensive studies focusing on the above-mentioned circumstances, and uses an intaglio plate having concave portions for forming multicolor thick patterns to form multicolor thick patterns made of silicone rubber on felt cloth, etc. The purpose of the present invention is to provide a method for efficiently forming a multicolor thick pattern on a base material.

[Summary of the invention]

The present invention, which has been made to achieve the above object, is an intaglio plate in which a plurality of recesses for forming multicolor thick patterns are formed, and all of the recesses are moistened with a solvent such as toluene or gasoline. After filling the silicone rubber composition, heat is applied to volatilize the solvent in the silicone rubber composition and cure the composition. First, the cured silicone rubber is removed from the desired recesses. Empty the inside of the recess, fill the empty desired recess with an uncured silicone rubber composition colored in another color, and heat the uncured silicone rubber composition. By repeating the operation of volatilizing the solvent and curing (the number of colors of the thick wall pattern - 2) times, the cured silicone rubber colored in various colors is placed in the recesses, and then the silicone rubber of the desired color is placed. Empty the unfilled recess, and fill the gap between the empty recess and the recess formed in the step with uncured silicone rubber colored in another desired color;
Next, the base material is superimposed on the intaglio surface, heated and pressurized, and the silicone rubber filled in the recesses of the base material surface is transferred and fixed, and then the base material is peeled from the intaglio surface, and the silicone rubber is transferred and fixed onto the intaglio surface. The gist of the present invention is a method for forming a multicolor thick pattern, which is characterized by forming a multicolor thick pattern made of rubber on the base material.

[Detailed description of the invention]

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a process explanatory diagram of the present invention. In the figure, (1

In the present invention, first, a plurality of recesses (2), (3)
, (4), and (5) are all filled with a swollen silicone rubber composition (6) containing a solvent such as acetone, toluene, gasoline, mineral spirit, IIHL (see Figure 1). , heated to form a silicone rubber composition (
6) The solvent inside is volatilized and hardened.

When the solvent is evaporated, the volume of the silicone rubber composition (6) decreases, and a gap ( The size of the reference λ gap (7) in which the force is generated (Fig. 1) can be arbitrarily set by appropriately selecting the solvent contained in the silicone rubber composition (6). The gap (7) can be increased by using a silicone rubber composition with a high solvent content.

Next, the silicone rubber (8) cured in the above step is removed from the desired recess (2), and the desired recess (2) is emptied (see opening in Figure 1), and the emptied desired recess (
2) is filled with an uncured silicone rubber composition colored in a desired other color (swelled by containing a solvent in the same manner as 9 silicone rubber composition (6)), and heated to obtain the other color. The operation of volatilizing the solvent contained in the colored silicone rubber composition and curing it (number of colors of thick wall pattern - 2)
Repeat only once.

In this example, the thick pattern has four colors, so
The above operation only needs to be performed one more time (the operation of filling the recess (3) with silicone rubber composition a).

The state at this time is shown in FIG. (It will be understood that gaps are created on the cured silicone rubber even in the recesses of the misalignment.

Following the above process, it should not be filled (・
