Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for imparting a swelling pattern to a sheet material such as cloth using a foaming agent.

[0002]

2. Description of the Related Art It is conventionally known that a pattern is formed on a cloth with a foaming agent and then foamed to give a raised pattern to the cloth (for example,
JP-A-52-110975). In order to further enhance the appearance of such a raised pattern, a foaming agent colored with a pigment or the like is used. Improvements have also been devised.

[0003]

SUMMARY OF THE INVENTION The present invention is a fabric using a foaming agent (generally applicable to sheet materials).
The present invention relates to a further improvement in imparting a raised pattern to the top.

[0004]

Means and Actions for Solving the Problems A first method (first method) for applying a raised pattern to a sheet material according to the present invention.
According to the invention), a foaming agent is applied to a sheet material in a desired pattern, and then the foaming agent is foamed while being pressed by a mold having an uneven pattern engraved on the surface, thereby giving a rising pattern having an uneven pattern on the surface. It is a thing.

The mold used here may be a flat mold having a flat surface or a female mold having a concave portion adapted to the coating pattern of the foaming agent. In the case of a flat type, a fine concavo-convex pattern is formed on the surface by machining, etching or the like. At the time of foaming, the surface of the flat mold is fixed to be slightly separated from the surface of the sheet material so that the surface of the foaming agent after foaming contacts the surface of the flat mold. In the case of a female mold, a fine concavo-convex pattern is engraved on the bottom of the recess and / or the side of the recess. At the time of foaming, the concave part may be aligned with the coating pattern so that the surface of the mold is placed in close contact with the sheet material to prevent the foaming agent from spreading laterally, or the surface of the mold may be placed slightly away from the sheet material. , You may allow some lateral spread. In any case, the application amount of the foaming agent and the volume of the concave portion are estimated in advance so that the foaming agent after foaming fills the inside of the concave portion of the mold and the uneven pattern engraved on the concave portion is transferred to the foaming portion. It is preferable.

A second method (second invention) is to apply a foaming agent to a sheet material in a desired pattern, embroider on the pattern, and then foam the foaming agent to embroider. This is to give a swelling pattern in which the above are mixed to the sheet material.

The embroidery carried out after applying the foaming agent is a little rough.
Moreover, loosening provides a better balance of mixing with the foaming agent after foaming. Note that the embroidery area (embroidery pattern) does not necessarily need to match the entire surface with the foaming agent application pattern. Embroidery may be applied over the part, and a unique effect may be produced by the confusion of both patterns.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the first invention will be described with reference to FIGS. In addition, the cloth in the attached drawings is drawn with a very rough eye to make it easy to understand that it is a cloth, and the relative relationship between the size of the eye and the size of the foaming agent application pattern, mold, pattern etc. Is not necessarily as shown in the figure. In this embodiment, first, a flat mold 14 having an uneven pattern 15 on its surface as shown in FIG. 2A is prepared. The uneven pattern 15 may be created by machining or engraved by etching. Further, the material of the mold 14 does not necessarily have to be metal, and may be hard plastic or the like.

In this embodiment, a raised pattern of the letter "A" is formed on the fabric 11 as shown in FIG. The foaming agent is applied to the fabric 11 in a slightly finer area than the pattern in consideration of the width expansion after foaming. The foaming agent may be applied by directly drawing with a brush, or may be applied by using a hole mold. Then, as shown in FIG. 2B, the flat mold 14 is placed slightly away from the surface of the fabric 11,
The foaming agent 12 is foamed. As the foaming agent, a commercially available forming binder or silicon binder can be used, and the foaming conditions are as specified for each foaming agent (generally, both the forming binder and the silicon binder are 110 to 130 ° C.). About 2-3 minutes.
Depending on the foaming agent, it may be foamed by causing a chemical reaction with another agent). Flat type 1
The distance between the fabric 4 and the fabric 11 is set so that the surface of the foamed portion 12 after foaming contacts the surface of the mold 14 in consideration of the volume expansion coefficient of the foaming agent. Thereby, the foamed portion 12 after foaming
An uneven pattern 13 (corresponding to the uneven pattern 15 on the surface of the flat mold 14) appears on the surface of the. A metal foil may be placed in advance between the cloth 11 and the mold 14 after applying the foaming agent, and the surface of the foamed portion 12 (the surface on which the fine pattern 13 is applied) may be covered with the metal foil. .

A second embodiment of the first invention will be described with reference to FIG. In this embodiment, a female mold 24 as shown in FIG. 3 (b) is used. The mold 24 is formed with a concave portion 25 having the same pattern as the raised pattern 22 (FIG. 3A) to be formed, and a fine uneven pattern 26 (in the example of FIG. 3, " Engrave the letters "ELLE" and many parallel lines. Also in this embodiment, the mold material may be either metal or plastic.

As shown in FIG. 3C, on the fabric 21,
A foaming agent is applied to an area slightly narrower than the recess 25 of the female die 24, and the female die 24 is placed according to the pattern. In this state, the foaming agent is foamed under specified conditions to fill the recess 25. As a result, as shown in FIG. 3A, the foamed portion 22 having the desired pattern with the fine pattern 23 on the surface is formed on the sheet material 21. Also in this embodiment, a metal foil may be placed in advance between the cloth 11 and the mold 14, and the surface of the foamed portion 22 (the surface on which the fine pattern 23 is provided) may be covered with the metal foil.

FIG. 4 shows an embodiment (third embodiment) of the second invention.
Will be described. In this embodiment, as shown in FIG. 4B, the foaming agent 34 is applied on the cloth 31 in advance in a desired pattern, and the portion 34 is embroidered so as to cover it. After finishing the embroidery, foaming is performed under the conditions specified by the foaming agent.
As shown in (a), the foaming agent 32 raises the embroidery thread 33, and a pattern in which the embroidery thread 33 and the foaming agent 32 after foaming are mixed is formed on the fabric 31. In this embodiment, before foaming, the thread is slightly loosened for embroidery to leave room for expansion of the foaming agent, and the seams are also roughened.
It is preferable to allow the foaming agent to swell to some extent between the threads (provided that the thread is not buried in the foaming agent).

[0013]

The swelling pattern (pattern) imparted by the method according to the present invention has a new form that has never existed before, and has a novel appearance with respect to all articles using cloth such as clothes, bags and the like. Can be given. In addition to the cloth used in the above examples, the sheet material,
Sheets of various materials such as vinyl sheets can be used.
