Abstract

PURPOSE:To obtain a stereoscopic accessory having a soft unevenness by providing means such as interposing a material in which cloth printed on its outer surface is laminated on an outer surface of a sheetlike sponge made of thermoplastic soft synthetic resin between upper concave and lower convex molds. CONSTITUTION:In order to manufacture an accessory 11, molds having an upper mold 2 having a recess 1 on a lower surface and a lower mold 4 having a protrusion 3 on an upper surface are first prepared. Simultaneously, a material 8 in which knitted fabric 6, for example, previously printed 5 on its outer surface is laminated on an outer surface of a sheetlike sponge 7 made of thermoplastic soft synthetic resin. Then, the material 8 is interposed between the molds 2 and 4 with the fabric 6 disposed upside in an advanced state. Thereafter, the molds 2, 4 are heated, pressurized, and the sponge 7 of the material 8 is held until heating and pressure molding of the mold recess 1 and protrusion 3 are completed. Then, heated and pressure molded article 9 is released, its excess part 10 is cut OFF, and hence a stereoscopic accessory 11 is completed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a soft three-dimensional accessory which is attached to a backpack, bag, bag or the like to beautify the same.

[0002]

2. Description of the Related Art Conventionally, a vinyl lower sheet, a vinyl sponge medium sheet, and a vinyl upper sheet are polymerized, and then the upper, middle, and lower sheets in the polymerized state are fused and compressed by a blade portion of a high-frequency adhesive means. A three-dimensional patch obtained by applying welding is disclosed in Japanese Patent Publication No. 48-33360.

[0003]

The patch described in the above prior art is one in which the upper sheet is swollen by the expansive force of the sponge-like medium sheet to form a three-dimensional portion, and the swollen amount (unevenness difference) ) Was not that big.

An object of the present invention is to provide a manufacturing method for obtaining a novel accessory having a soft three-dimensional portion having a large bulge amount (unevenness difference).

[0005]

In order to achieve the above object, a method of manufacturing an accessory according to the present invention is to provide a mold comprising one mold having a concave part on a mating surface and the other mold having a convex part on a mating surface. Separately from this, prepare a material in which a cloth such as a knitted fabric that has been printed on the outer surface in advance is laminated on the outer surface of a sheet-like sponge made of a thermoplastic soft synthetic resin. The cloth such as knit is sandwiched as an extended state that becomes the outside when completed, and after this sandwiching, both molds are kept in a heated / pressurized state for a certain period of time,
After this holding, it is cooled and die-cut.

[0006]

Embodiments of the present invention will be described with reference to the drawings.
First, an upper mold 2 having a concave mold portion 1 on the lower surface and a convex mold portion 3 on the upper surface.
A mold including a lower mold 4 having a is prepared. Separately from this, a cotton knit 6 with a print 5 on the outer surface beforehand.
A raw material 8 is prepared by laminating the sheet-shaped sponge 7 made of thermoplastic soft synthetic resin such as vinyl on the outer surface. After that, this material 8 is placed between the upper and lower molds 2 and 4 and the knit 6
It is inserted as a stretched state with the upper side (see Fig. 1).
After this sandwiching, the upper and lower molds 2 and 4 are heated and pressed (see FIG. 2), and the heated and pressed condition is kept for a predetermined time, that is, the sheet-shaped sponge 7 of the material 8 is formed by the concave and convex mold portions 3. It is held until the time when heating / pressurizing is completed, after which it is cooled and the mold is opened to take out the heating / pressurizing product 9. The three-dimensional accessory 1 is obtained by cutting the surplus portion 10 from the molded product 9.
1 and complete this accessory 11 rucksack 1
It is fixed to the outer surface of 2.

It is desirable to devise the print 5 so that it does not become ugly due to deformation caused by three-dimensionalization. When the rucksack 12 is attached to the outer surface of the rucksack 12, it is possible to store batting in the accessory 11. Further, there may be a case where the mating surface of one mold is provided with a concave part and a convex part, and the mating surface of the other mold is provided with a convex part and a concave part.

[0008]

[Function] Sheet-shaped sponge 7 made of thermoplastic soft synthetic resin
Is semi-melted and thinned in the case of the above heating / pressurization, and solidified in the thinned state and the deformed state by the concave / convex mold portions 1 and 3 in the case of cooling after the heating / pressurization.

[0009]

According to the manufacturing method of the present invention, a solid three-dimensional accessory having a large amount of bulging (unevenness difference) and having soft unevenness, which is obtained by heating and pressure molding with a mold, can be completed easily and surely.

Claims (1)

[Claims] 1. A mold comprising a one-sided mold having a concave part on the mating surface and another mold having a convex part on the mating surface is prepared. Separately from this, a cloth such as a knitted fabric having an outer surface printed beforehand is prepared. Prepare a material laminated on the outer surface of a sheet-like sponge made of thermoplastic soft synthetic resin, and then sandwich this material between both molds as a stretched state that the cloth such as knitting will be the outside when completed, A method for manufacturing an accessory, characterized in that both molds are heated and pressed for a certain period of time after being sandwiched, and then cooled and then die-cut.
