  In the case of the above conventional technology, when the fabric to be embossed does not have air permeability or has air permeability, it is difficult to completely remove the air layer sandwiched between the back surface of the fabric and the adhesive layer within the processing time. In the case of dough, an air layer may remain after heating and pressing. If the air layer remains, the product may not be a product due to poor appearance.

  Further, in the three-dimensional raised mat disclosed in Patent Document 1, the sheet sandwiching the foam from both sides is, for example, a cloth such as cotton, polyester, or nylon, and has sufficient air permeability and an air layer remains. There is no need for a means for venting air. For this reason, use for a sheet having no air permeability is not considered.

  The present invention has been made in view of the above-mentioned problems of the prior art, and a fabric that does not have air permeability or an air layer that has air permeability but is sandwiched between the back surface of the fabric and the adhesive layer has a processing time. An object of the present invention is to provide an embossed sheet in which air is surely escaped and bonded to a fabric which is difficult to be pulled out, and can be neatly decorated by forming an emboss on the fabric.

  The present invention is provided with a resin sheet formed of a resin, an adhesive layer attached to one side of the resin sheet and made of a thermoplastic resin, and an air hole penetrating the resin sheet and the adhesive layer. The sheet and the adhesive layer are embossed sheets that are embossed to form convex portions and concave portions, and a desired pattern is formed by the convex portions and the concave portions. The embossed sheet has a fabric that does not have the breathability of the desired product or a fabric that has poor breathability, for example, an air layer that has breathability but is sandwiched between the back surface of the fabric and the adhesive layer within the processing time. The pattern is provided on the fabric by forming the projections and depressions along the recesses by adhering to the fabric that is difficult to pull out completely.

  A plurality of the air holes are provided, and the convex portion is positioned substantially at the center thereof, and the concave portion is positioned at a corner near the convex portion. The air holes may be formed by a laser beam.

  The resin sheet and the adhesive layer are polyurethane. The adhesive layer may be provided by attaching a polyurethane adhesive sheet. In this case, the resin sheet is applied with an embossing die, and the adhesion sheet and the unevenness are simultaneously formed by a high frequency welding machine.

  Further, when the embossed sheet is adhered to the product fabric, the embossed sheet is applied to the product fabric by a high-frequency welding machine by applying an embossing die to form unevenness of the fabric.

  The embossed sheet of the present invention can be applied to fabrics that do not have air permeability or fabrics that have air permeability but the air layer sandwiched between the back surface of the fabric and the adhesive layer is difficult to completely remove within the processing time. It is possible to decorate the fabric by making sure that it is released and bonded, and that the emboss is neatly formed on the fabric. The air layer is surely prevented from remaining on the part bonded to the fabric, and the product yield is improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 and 2 show an embodiment of the present invention. An embossed sheet 10 of this embodiment is provided with a flexible resin sheet 12 serving as a base material, and an adhesive layer is formed on a surface 12a of the resin sheet 12. 14 is provided. The resin sheet 12 is made of, for example, thermoplastic polyurethane and has a thickness of 500 μm. The adhesive layer 14 is provided by sticking a hot melt adhesive sheet such as polyurethane, for example, to the resin sheet 12 and has a thickness of 50 μm.

  The resin sheet 12 and the adhesive layer 14 stacked on each other are pressed to form a convex portion 16 from which the front surface 12a of the resin sheet 12 protrudes, and a concave portion 18 from the front surface 12a from which the rear surface 12b protrudes. A pattern 20 such as a parallelogram, a star, or a frame is provided by the convex portion 16 and the concave portion 18. Each convex portion 16 is provided with an air hole 22 penetrating the resin sheet 12 and the adhesive layer 14, and the air hole 22 is located at the approximate center of the convex portion 16. The concave portion 18 is continuously provided in a portion other than the convex portion 16, and air holes 22 are also provided at several locations of the concave portion 18. The air hole 22 of the concave portion 18 is located at a corner located in the vicinity of the convex portion 16.

Next, the manufacturing method of the embossed sheet | seat 10 is demonstrated based on FIG. First, as shown in FIG. 3A, an adhesive sheet to be an adhesive layer 14 is stacked on the surface 12a of the resin sheet 12, and in this state, the laser beam 24 is irradiated to cut the periphery into a desired shape, and at the same time, air holes 22 is formed. A laser processing machine that irradiates a laser beam uses, for example, a CO ₂ laser device. Next, as shown in FIG. 3B, the resin sheet 12 and the adhesive layer 14 that are stacked on each other are set on an embossing die 26. The resin sheet 12 side is placed on the male mold 26 a of the embossing mold 26. At this time, if there is release paper on the resin sheet 12 or the adhesive layer 14, it is peeled off before placing. Next, the female die 26b of the embossing die 26 is placed from the adhesive layer 14 side, and the resin sheet 12 and the adhesive layer 14 are adhered, and the convex portion 16 and the concave portion 18 are simultaneously formed by a high frequency welding machine. The pattern 20 is provided by the convex portion 16 and the concave portion 18. And it becomes the embossing sheet | seat 10 shown in FIG.3 (c).

  Next, a method for using the embossed sheet 10 will be described with reference to FIG. The embossed sheet 10 is set on the embossing die 26. As in the previous attachment of the resin sheet 12 and the adhesive layer 14, the placement is performed so that the resin sheet 12 side contacts the male mold 26a and the adhesive layer 14 faces the female mold 26b. On the adhesive layer 14, a cloth 30 of the garment 28 to which the embossed sheet 10 is attached is placed. The fabric 30 is laminated on the back surface and has air permeability, but it is difficult to completely remove the air layer sandwiched between the back surface of the fabric and the adhesive layer within the processing time. At this time, the fabric 30 is set so that the back surface 30a of the dough 30 contacts the embossed sheet 10. Next, a female die 26b of the embossing die 26 is placed from the surface 30b side of the dough 30 and the dough 30 and the embossed sheet 10 are bonded by a high frequency welding machine. Thereby, the cloth 30 is bent along the convex portions 16 and the concave portions 18 of the embossed sheet 10 to provide the pattern 20. Since the air remaining between the fabric 30 and the adhesive layer 14 of the embossed sheet 10 passes through the air holes 22 of the embossed sheet 10 and escapes to the back surface 12b of the embossed sheet 10, the air layer is separated from the adhesive layer 14 and the fabric. It will not remain between 30.

  According to the embossed sheet 10 of this embodiment, it is possible to reliably form clean irregularities on the fabric 30 of the clothes 28 and to provide the pattern 20. Even with the fabric 30 that has air permeability but the air layer sandwiched between the back surface of the fabric and the adhesive layer is difficult to be completely removed within the processing time, the air between the embossed sheet 10 escapes from the air holes 22. Therefore, an air layer does not remain between the dough 30 and the embossed sheet 10, the product yield is improved, and the working efficiency is improved. The air holes 22 are provided in the vicinity of the center of the convex portion 16 and the corner portion of the concave portion 18 and are provided in a portion where air is likely to remain, so that air can be surely extracted. Since the pattern 20 is neatly provided on the fabric 30, the clothes 28 can be made of the fabric 30 having various functions such as waterproof and windproof functions. Since the air hole 22 is small, it does not affect the surface 30b of the dough 30 and has a clean appearance.

  In addition, the embossed sheet of this invention can be changed as appropriate, the material and thickness of the resin sheet and the adhesive layer of the embossed sheet can be set as appropriate, and the shape of the embossed sheet and the design of the pattern are adapted to the product. It can be set freely. The embossed sheet can be attached to various types of clothes, and in addition to clothes, it can be attached to small items such as bags, hats, and gloves.
