The slide fastener is attached so as to face the cut portion on the back surface of the fabric.

  However, in the case of the above technique by the inventor of the present application, when a natural fabric such as cotton or wool is used, the fabric may be burnt by laser light, and fraying of the end portion cannot be prevented. In addition, the fabric and the synthetic resin tape may be peeled off during use. Furthermore, even if the cloth is made of synthetic resin, the laminated portion may be peeled off by use at the cut surface by the laser light in the cloth having a laminated structure.

  The present invention has been made in view of the above-described conventional problems, and has a simple structure and a good appearance, and a fabric end structure and fabric that are protected by reliably preventing fraying and peeling of the cut fabric end. It is an object of the present invention to provide an edge processing method.

  The present invention includes a pair of synthetic resin sheets that are attached to the front and back surfaces of the fabric and that extend laterally from the ends of the fabric and are bonded to each other, and the pair of synthetic resin sheets are separated from the ends of the fabric. This is a fabric end structure in which a cut portion is formed by cutting at the place.

  The synthetic resin sheet is a hot-melt film or a hot-melt sheet of a thermoplastic resin obtained by molding a thermoplastic resin into a sheet shape. The cut portions of the pair of synthetic resin sheets are formed by laser light penetrating the synthetic resin sheet.

Furthermore, a through-hole is formed in the cloth, the end portion goes around the through-hole, and the pair of synthetic resin sheets are attached to the front and back surfaces of the cloth so as to cover the through-hole. The pair of synthetic resin sheets are formed with a predetermined width in the through hole, and the fastener tape of the slide fastener is attached to the back surface of the fabric so as to face the cut portion. Further, the present invention, on the front and back surfaces of the fabric, extending from the end of the fabric to the side and pasting a synthetic resin sheet, bonding the portions of the synthetic resin sheet extending from the end of the fabric to each other, In this method, the pair of synthetic resin sheets are cut from the pair of synthetic resin sheets with a laser beam at a position away from the end of the cloth to form a cut portion.

  The cloth edge structure and the cloth edge processing method of the present invention can reduce the thickness of the cloth edge, have a good appearance, and can surely prevent fraying and peeling. For this reason, members, such as a fastener, can also be easily attached to various fabric edge parts.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 3 show a first embodiment of the present invention. A fabric end structure 10 according to this embodiment is a slide described later at a predetermined position of a fabric 12 having a laminated structure in which synthetic resin materials are laminated. The fastener 20 is attached.

  A through hole 13 is formed in the fabric 12 at a position where the slide fastener 20 is attached. The peripheral edge of the through hole 13 is formed as an end 12 a of the fabric 12. On the surface 12b of the dough 12, a film 14 with hot melt that covers the through holes 13 and the end 12a of the dough 12 with a predetermined width is fused and attached. The film with hot melt 14 is obtained by laminating a synthetic resin film with a hot melt material of ester polyurethane which is a thermoplastic resin.

  A hot melt sheet 16 that covers the through holes 13 and the end portions 12a of the dough 12 with a predetermined width is melted and bonded to the back surface 12c of the dough 12. The hot melt sheet 16 is also formed by molding an ester polyurethane of a thermoplastic resin into a sheet shape. A reinforcing material 18 is bonded to the surface of the hot melt sheet 16 opposite to the dough 12. A slide fastener 20 is attached to the surface of the reinforcing member 18 opposite to the hot melt sheet 16. As for the attachment method of the slide fastener 20, the fastener tape 22 of the slide fastener 20, the hot melt sheet 16, and the reinforcing material 18 are sewn with a thread 24.

  The film 14 with hot melt, the hot melt sheet 16, and the reinforcing material 18 are bonded and integrated with each other inside the through hole 13 of the fabric 12. The hot melt-attached film 14, the hot melt sheet 16, and the reinforcing material 18 which are bonded to each other are formed in a substantially linear cut portion 26 having a predetermined width at a position away from the end 12a of the fabric 12 in the through hole 13. Has been.

  The excision part 26 is formed by laser processing, and the shape of the excision part 26 is, as shown in FIG. 3, a thin linear line part 26a, and both ends of the line 26a, and the major part in the line part 26a. Is formed by an elongated round cut portion 26b. The element 21 of the slide fastener 20 located on the back surface 12c of the fabric 12 faces the line portion 26a of the cut portion 26, and a slider (not shown) of the slide fastener 20 is exposed to the cut portion 26b. In the slide fastener 20 of this embodiment, the element 21 protrudes on the surface opposite to the fabric 12 side with respect to the fastener tape 22, and the element 21 hardly protrudes on the fabric 12 side.

  Next, the processing method of the fabric end structure 10 of this embodiment will be described with reference to FIG. First, the through holes 13 are cut out in the dough 12. Moreover, the film 14 with a hot melt, the hot melt sheet 16, and the reinforcing material 18 are processed into a predetermined shape by laser light. A release paper (not shown) is attached to one side of the hot melt sheet 16 in advance. Then, the surface of the hot melt sheet 16 without the release paper is bonded to the reinforcing material 18. Then, the release paper of the hot melt sheet 16 is peeled off to a size that covers the portion covering the shape of the through-hole 13 of the dough 12 and its periphery with a slight predetermined width, and the hot melt sheet 16 is adhered to the back surface 12 c of the dough 12. To do. At this time, the part of the hot melt sheet 16 from which the release paper has been peeled adheres to the position covering the through hole 13. Next, the film 14 with hot melt is bonded to the surface 12 b of the dough 12. At this time, the film 14 with hot melt adheres to the hot melt sheet 16 exposed in the through holes 13 of the dough 12. That is, the film 14 with hot melt, the hot melt sheet 16, and the reinforcing material 18 are bonded to each other in the through-hole 13 of the fabric 12 and integrated.

  Next, in the through-hole 13, a cut portion 26 having a predetermined shape is formed by laser light on the film 14 with hot melt, the hot melt sheet 16, and the reinforcing material 18. Thereafter, the remaining release paper of the hot melt sheet 16 is peeled off, and the slide fastener 20 is sewn with the thread 24. The hot melt sheet 16 is bonded to the fabric 12 together with the yarn 24.

  According to the fabric end portion structure 10 of this embodiment, it is a thin and simple structure, and for the fabric 12 having a laminated structure, it is possible to reliably prevent peeling of each layer at the end of the fabric 12. Then, the film 14 with hot melt, the hot melt sheet 16, and the reinforcing material 18 can be attached to the end 12a of any shape by cutting with a laser beam in accordance with the shape of the end 12a of the fabric 12. . The cut portion 26 can be formed into a free shape with a laser beam, and the design is improved. Further, it is not necessary to fold and sew the end portion 12a of the fabric 12 in order to prevent the fabric 12 from being peeled off. In particular, the clutter of the pocket mouth is reduced and the design is refreshed. Since the end 12a of the dough 12 is sandwiched between the film 14 with hot melt 14 and the hot melt sheet 16, and the cut portion 26 is bordered at the portion where the film 14 with hot melt 14 and the hot melt sheet 16 are bonded together, No fraying or peeling of the laminated material of the fabric 12 occurs. Therefore, for example, when the slider of the slide fastener 20 slides, the end portion 12a of the fabric 12 does not rub against each other, which is durable. Since the end 12a of the fabric 12 does not peel off, the slide fastener 20 can be easily attached. Moreover, since the slide fastener 20 can be attached even in the part in the fabric part, the degree of freedom in design is improved. Moreover, the thread 24 does not come out on the surface 12b of the fabric 12, and this also makes the design neat. In addition, this structure makes the dough 12 firm and prevents it from being caught by the slider of the slide fastener 20, and also can hide the unevenness of the slide fastener 20. Since the slide fastener 20 is attached so that the element 21 protrudes on the opposite side to the fabric 12, the element 21 is not conspicuous at the cut portion 26, and the surface of the fabric 12 is clean.

  In addition, the material edge processing method according to this embodiment can significantly reduce the number of processing steps, shorten the installation time, and greatly reduce the cost as compared with the prior art.

  Next, a second embodiment of the present invention will be described. Here, the same members as those in the above embodiment are denoted by the same reference numerals, and the description thereof is omitted. FIG. 4 shows a second embodiment of the present invention. The fabric end structure 28 of this embodiment attaches the slide fastener 20 to a predetermined position of a fabric 30 made of a natural material such as cotton or wool. Is.

  A through hole 32 is formed in the fabric 30 at a position where the slide fastener 20 is attached. The peripheral edge of the through hole 32 is formed as an end portion 30 a of the fabric 30. A film 34 with hot melt that covers the through holes 32 and the end portions 30a of the dough 30 with a predetermined width is attached to the surface 30b of the dough 30 by bonding. Further, a hot melt sheet 36 that covers the through holes 32 and the fabric end portions 30a with a predetermined width is bonded to the back surface 30c of the fabric 30 as well. A slide fastener 20 is attached to the surface of the hot melt sheet 36 opposite to the fabric 30. The slide fastener 20 is attached in such a manner that the fastener tape 22 of the slide fastener 20 and the hot melt sheet 36 are sewn with the thread 24.

  Next, the processing method of the fabric end structure 28 of this embodiment will be described. The surface of the hot melt sheet 36 without the release paper is aligned with the back surface 30c of the dough 30 and covers the through holes 32 and adheres. Further, a film 34 with hot melt is bonded to the surface 30 b of the dough 30 so as to cover the predetermined widths of the through holes 32 and the peripheral edge thereof. At this time, the film 34 with hot melt adheres to the hot melt sheet 36 exposed in the through holes 32 of the dough 30. Then, the release paper of the hot melt sheet 36 is peeled off. Inside the through-hole 32, a cut portion 38 having a predetermined shape is formed in the film 34 with hot melt and the hot melt sheet 36 by laser light. Next, the slide fastener 20 is sewn to the fabric 30 and the hot melt sheet 36 with the thread 24.

  According to the fabric end portion structure 28 of this embodiment, the same effects as those of the above embodiment are obtained. Further, the fabric end portion 30a of the fabric 30 made of natural material can be protected by the hot melt-attached film 34 and the hot melt sheet 36, thereby eliminating fraying and improving durability. Since the cut portion 38 is attached to the hot melt-attached film 34 and the hot melt sheet 36 by a laser, the dough 30 made of a natural material is not damaged because the dough 30 is not laser processed.

  The fabric end structure and the fabric end processing method of the present invention are not limited to the above embodiments, and can be used even when a slide fastener is not attached. It can be used in various places such as the end of the door and the outlet for small items. The material of each member such as a hot melt sheet can be appropriately changed.
