It is a manufacturing process figure of the sheet for decoration concerning the embodiment of the present invention. It is a figure which shows the jig | tool sheet | seat used when manufacturing the decorative sheet which concerns on embodiment of this invention, Comprising: (a) is the top view, (b) is the sectional drawing, (c) is a jig of another example. It is sectional drawing of a sheet | seat. It is a partially expanded sectional view of the decorative sheet according to another embodiment of the present invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the decorative sheet 1 of the present embodiment has a decorative dot part 2 having a convex upper surface 20 on the upper surface and a flat fixed surface 21 on the bottom surface, and an adhesive layer 31 on the back surface. The application sheet 3 that is adhesively held so as to wrap the convex upper surface 20 of the decorative dot part 2 and the release sheet 4 that is detachably bonded to the back surface of the application sheet 3 with a plurality of decorative dot parts 2 interposed therebetween. .

  The decorative dot part 2 uses studs, rhinestones, beads, sequins, metal dots, and the like, and can be formed by processing metal, plastic, various natural stone materials, glass materials, and the like. A decorative dot part 2 shown in FIG. 1 is formed in a quadrangular pyramid shape, a dome shape, a star shape, or the like, and a predetermined pattern is formed by using each shape type having an uneven upper end height. The decorative dot part 2 is not limited to the shape described above, and may be various shapes such as a diamond shape and a cylindrical shape. Also, the decorative dot part 2 may be different in at least one of height, shape, and material, as shown in FIG. As described above, the same height, shape, and material may be provided.

  The decorative dot part 2 is an adhesive in which the upper surface 20 is convex and the bottom surface side has a concave portion 22a on the inner side excluding the outer edge, and the concave portion 22a is filled with a hot melt adhesive or a pressure sensitive adhesive. Part 23. When the decorative dot part 2 is a metal stud, for example, the part main body 22 is made of a metal that is molded into a predetermined shape so as to form a recess 22a. The bottom surface of the decorative dot part 2 is filled with a hot melt adhesive or a pressure sensitive adhesive in the recess 22a of the part main body 22 so that the flat fixing surface 21 is formed. Since the recess 22a can sufficiently secure a hot melt adhesive or the like for adhering the decoration dot part 2 to the decoration object, the decoration dot part 2 can be reliably adhered to the decoration object. The decorative dot part 2 may be a flat surface in which the recess 22a is not formed on the bottom surface. In this case, an adhesive is applied to the flat bottom surface to form the fixing surface 21. In the present embodiment, the fixing surface 12 is formed of a hot melt adhesive. Since this hot melt adhesive is bonded by being melted by heating and solidifying by cooling, not only clothes, sewing products, fabrics, leather products, etc. but also glass, plastic, etc. Even the surface of the hard material can be securely bonded by imparting fluidity by heating and melting.

  The application sheet 3 has an adhesive layer 31 on the back surface and is made of a material excellent in stretchability and flexibility so as to wrap the convex upper surface 20 of each of the plurality of decorative dot parts 2 one by one. The application sheet 3 is preferably transparent or translucent so that the plurality of decorative dot parts 2 arranged in a predetermined decorative pattern can be seen from the outside, but may be opaque. As a material of the application sheet 3, for example, a paper sheet such as a Japanese paper or a masking seal material may be used in addition to a resin film such as polypropylene, polyethylene terephthalate, polyurethane, PVC, or vinyl chloride. In order to wrap the decorative dot parts 2 more reliably one by one as the application sheet 3, when using a polypropylene film, one having a thickness in the range of 1 to 3000 μm is used, preferably 50 to 150 μm. Things are used. In the case of using a paper sheet, one having a thickness in the range of 1 to 3000 μm is used, preferably 100 to 300 μm. In addition, when a hot melt adhesive is used for the fixing surface 21 of the decorative dot part 2, the application sheet 3 is preferably a resin film that is softened and molded at a temperature lower than the melting temperature of the hot melt adhesive. In this embodiment, the application sheet 3 uses a transparent polypropylene film having a thickness of 100 μm.

  The adhesive layer 31 on the back surface of the application sheet 3 decorates each decorative dot part 2 while sufficiently sticking and holding each of the plurality of decorative dot parts 2 to the application sheet 3 so as to wrap the convex upper surface 20. After removing the application sheet 3 after being transferred and fixed to the object, an adhesive is used that holds the adhesive dot part 2 relatively weakly so that the decoration dot part 2 does not peel off the decoration object. An acrylic pressure-sensitive adhesive is used, but not limited to this, various pressure-sensitive adhesives such as urethane can be used. Further, the adhesive strength of the adhesive layer 31 of the application sheet 3 is weaker than the adhesive strength of the decorative dot part 2 to the decoration object by the fixing surface 21.

  As the release sheet 4, a surface of a base sheet made of paper or resin is coated with a silicone resin or a fluororesin as a release agent. For example, a release agent is applied to a base sheet such as glassine paper or fine paper. The coated one is used.

Next, a manufacturing method of the decorative sheet 1 according to the present embodiment will be described based on the manufacturing process diagram of FIG.
First, as shown in FIG. 3A, a jig sheet 5 for arranging the decorative dot parts 2 in a predetermined decorative pattern is arranged on a press table 61 of a press machine. The jig sheet 5 is formed of masking sheet paper, glassine paper, plastic sheet, etc., and the surface thereof is subjected to fluorine processing or silicone processing so as to have releasability. Many parts accommodating parts 51 to be arranged one by one are formed. In this embodiment, as shown in FIGS. 4 (a) and 4 (b), a part accommodating portion comprising a masking sheet having a predetermined thickness and a through-hole having a different shape such as a circle, a star, or a rectangle. A number 51 is formed so as to constitute a predetermined pattern. The depth of the part accommodating part 51 is a depth at which more than half, preferably 60% or more of the surface area of the convex upper surface 20 of the decorative dot part 2 protrudes. In this embodiment, since the parts accommodating part 51 consists of a through-hole, the thickness of the jig sheet 5 becomes the depth of the parts accommodating part 51. In addition, the shape and size of each part accommodating portion 51 is formed slightly larger than the outer shape of the decorative dot part 2, and when the decorative dot part 2 is dropped into the part accommodating portion 51, the decorative dot part 2 is slightly idle. In a certain state, it is sized to be received in the parts accommodating portion 51. In addition, like the jig sheet 5A shown in FIG. 4C, the parts accommodating portion 51a may be a concave portion formed by embossing or the like.

  Next, as shown in FIG. 3 (b), the decorative dot parts 2 matching the shape are arranged with respect to each part accommodating part 51 of the jig sheet 5 so that the fixing surface 21 faces the press stand 61 (decoration). Dot parts placement process). For example, the decorative dot parts 2 are scattered on the jig sheet 5, and the decorative dot parts 2 having the appropriate shapes are poured into the respective parts accommodating portions 51, and the fixing surfaces 21 are directed downward, and thus do not fit in the parts accommodating portions 51. The decorative dot parts 2 are collected. In this way, the decorative dot part 2 is easily accommodated in the part accommodating part 51 of the jig sheet 5.

  Then, as shown in FIG. 3C, the application sheet 3 is placed on the jig sheet 5 so that the back surface side on which the adhesive layer 31 is formed faces the jig sheet 5. Subsequently, the cushion material 62 is pressed from above the application sheet 3 toward the press table 61 (pressing step). The cushion material 62 is composed of, for example, a sponge sheet made of a foam of silicone rubber having a large number of closed cells and excellent in flexibility and heat resistance, and is attached to the iron plate 63 in order to pressurize the application sheet 3 uniformly. Yes. The cushion material 62 has a thickness that can be recessed along the shape of the convex upper surface 20 of the decorative dot part 2 protruding from the upper surface of the jig sheet 5, and for example, a sponge sheet having a thickness of 10 to 30 mm is used. The

When the cushion material 62 is pressed, the application sheet 3 is heated while being molded so as to wrap each of the decorative dot parts 2 while being heated. However, the application sheet 3 may be pressed without being heated. . In the case of hot pressing, it is advantageous in that the application sheet 3 can be satisfactorily stretched with a small pressing force. The cushion material 62 is heated by, for example, heating the iron plate 63 with a heater or the like. The heating temperature at the time of hot pressing is set to a temperature at which the application sheet 3 is softened by heat and does not melt the hot melt adhesive on the fixing surface 21 of the decorative dot part 2. A polypropylene sheet is used and heated at a temperature lower than the melting temperature of the hot melt adhesive of the decorative dot part 2 at 80 to 180 ° C, preferably about 160 ° C. In addition, the heating temperature at the time of this hot pressing can be set to a set temperature that does not exceed 400 ° C., depending on the material of the application sheet 3 and the type of hot melt adhesive of the decorative dot part 2. Further, as a pressing condition, the pressing force and the pressing time are set so that the application sheet 3 is softened and the fixing surface 21 of the decorative dot part 2 is not melted. In this embodiment, the pressing force is 1 kg / m ² , The pressurization time is 20 seconds.

  By the pressing process by the cushion material 62, the cushion material 62 is deformed so as to surround the convex upper surface 20 of the decorative dot part 2 via the application sheet 3, as shown in FIG. 3 is formed by extending along the convex upper surface 20 of each decorative dot part 2. As a result, the application sheet 3 has a convex upper surface 20 (at least a quarter of the height of the convex upper surface 20, preferably higher than the height of each of the decorative dot parts 2 protruding from the jig sheet 5. More than half.), It is molded so as to wrap in close contact with the entire surface. Thereby, even if the shape, size, and material of each of the decorative dot parts 2 are different, the application sheet 3 is adhesively held so as to wrap each convex upper surface 20 of each decorative dot part 2. It is possible to hold the various decorative dot parts 2 so as to form a predetermined pattern pattern without shifting the position by the single application sheet 3.

  Next, the application sheet 3 is peeled from the jig sheet 5 (jig sheet peeling step). At this time, since the surface of the jig sheet 5 has releasability, the application sheet 3 is smoothly peeled off from the next tool sheet 5 in a state where each decorative dot part 2 is wrapped and held in the convex upper surface 20. Then, as shown in (e) of FIG. 3, the application sheet 3 is in close contact with the convex upper surface 20 of each decorative dot part 2 protruding from the jig sheet 5. Since the upper surface portion within a certain height range from the lower end of the convex upper surface 20 is located in the part accommodating portion 51 of the jig sheet 5, it is not in contact with the application sheet 3. As a result, in each decorative dot part 2, this non-contact portion becomes a non-adhesion portion 24 that is not adhered to the application sheet 3.

  Although not shown, the release sheet 4 with the release surface facing upward is placed on the press stand 61 of the press machine, and the decorative dot parts 2 are wrapped on the back side of the release sheet 4. The application sheet 3 in a state of being adhesively held is overlapped so that the back side faces the release sheet 4, and the application sheet 3 is pressed from above with a rubber plate (not shown). As the rubber plate, for example, a low hardness silicone rubber sheet is used, and when the release sheet 4 is bonded to the rubber plate, the air release between the release sheet 4 and the application sheet 3 is sufficiently performed. In addition, you may make it further improve the adhesiveness with respect to the decoration dot part 2 of the application sheet | seat 3 by pressing the bonding of the peeling sheet 4 while heating. By the pressing by the rubber plate, the release sheet 4 is bonded to the back surface of the application sheet 3 with a plurality of decorative dot parts 2 sandwiched as shown in FIG.

  Through the above steps, as shown in FIG. 1, the decorative sheet in which the backing sheet that is also used as a mount is detachably bonded with the plurality of decorative dot parts 2 arranged in a predetermined pattern on the back surface of the application sheet 3. Sheet 1 is obtained. The decorative sheet 1 is closely attached so that each decorative dot part 2 wraps over the upper quarter of the height of the convex upper surface 20, preferably over the upper half, by the application sheet 3. The upper surface portion that is adhesively held and has a certain height range from the lower end has a non-adhesive portion 24 that is not adhered by the application sheet 3.

  In order to transfer the decorative dot part 2 from the decorative sheet 1 having the above configuration to a decorative object such as clothes, the application sheet 3 is peeled off from the release sheet 4 and the back side on which the decorative dot part 2 is adhered and held is decorated. The application sheet 3 is pressed and heated with an iron or the like together with the plurality of decorative dot parts 2 from above the application sheet 3. When the hot-melt adhesive of each decorative dot part 2 is melted, the iron is removed, the hot-melt adhesive is cooled and solidified to adhere each decorative dot part 2 to the object to be decorated, and then the application sheet 3 is peeled off. If the decoration dot parts 2 are separated from each other, the decoration object is decorated with a plurality of decoration dot parts 2 on the surface of the decoration object. In addition, when forming the adhering surface 21 of each decoration dot part 2 with a pressure sensitive adhesive, the decoration object is obtained by placing the application sheet 3 peeled off from the release sheet 4 on the decoration object and simply pressing from above. A decoration in which a plurality of decorative dot parts 2 are transferred and adhered can be applied to the surface. Even when the fixing surface 21 of the decorative dot part 2 is formed of either a hot-melt adhesive or a pressure-sensitive adhesive, the adhesive force of the fixing surface 21 of the decorative dot part 2 is the same as that of the adhesive layer 31 of the application sheet 3. Since the adhesive force is stronger than the adhesive, the decoration dot part 2 is reliably left on the decoration object when the application sheet 3 is peeled off.

  In addition, as decoration objects by the decorative sheet 1, not only clothes, bags, shoes, and other personal items, but also various kinds of electric devices such as mobile phones, tablet terminal devices, personal computers, and furniture, walls, and other articles. Can be the target.
