Description

  The present invention relates to a curtain sewing method, and more particularly, to a curtain sewing method suitable for manufacturing a light-shielding curtain.

  Conventionally, a light-shielding curtain having a function of blocking light has been provided. In recent years, a high level of light-shielding property required for the light-shielding curtain has been demanded. For example, there is a demand for shielding even a slight light leaking from a pin hole such as a sewing machine hole or a needle hole generated when sewing a curtain.

  In order to meet such demands, Patent Document 1 below discloses a shade curtain having a structure in which a pinhole of a seam is shielded from light. In Patent Document 1 below, a ring tape that holds a ring through which an operation string for raising and lowering a curtain fabric is inserted is sewn and attached to the backing interlining, and then heat fusion is applied to the opposite surface of the backing interlining. There is disclosed a sewing method in which a seamless outer material is thermocompression bonded through a material.

In this way, if the seam for attaching the ring tape is covered with the outer surface, the pinhole of the seam can be shielded from light.

  The light-shielding curtain 1 according to the present embodiment is a shade curtain that is tailored for only the outer surface 5, and, as shown in FIG. 1, three ring tapes 6 are provided on the back side of the outer surface 5 at predetermined intervals in the vertical direction. Is sewn. In order to shield the seam for attaching these ring tapes 6 and shield the pinholes, light shielding tapes 10e to 10f are installed.

  In addition, the edge portions of the four sides of the outer material 5 are respectively folded back and stitched together, but light shielding tapes 10a to 10d are installed at the edge portions of the four sides to cover the seams and shield the pinholes. Has been.

  As shown in FIG. 2, in the upper left corner portion of the light-shielding curtain 1, the left side folded portion 5 d where the left side edge portion of the outer material 5 is folded and the upper side folded portion 5 c where the upper edge portion of the outer surface 5 is folded are folded back. The light shielding tapes 10d and 10c are respectively affixed on the seams 20 of the portions 5d and 5c. As will be described later, one side of the light shielding tapes 10d and 10c is sandwiched between the folded portions 5d and 5c and stitched together, and the other side is folded and adhered onto the folded portions 5d and 5c. Is pasted. Further, since the seam 20 is hidden under the shading tape 10, it is indicated by a dotted line in FIG.

  In addition, as shown in FIG. 3, the ring tape 6 has the second tape fabric 8 at a predetermined interval in a state where the thin second tape fabric 8 is superimposed on the wide first tape fabric 7. It is formed by thermocompression bonding to the fabric (crimping portion 8a). Thereby, between the adjacent crimping | compression-bonding part 8a, the 1st tape fabric 7 and the 2nd tape fabric 8 will be in the state which is not joined, and a ring which is not illustrated here can be hooked and installed.

  And if the lifting / lowering cord suspended from the head box installed at the upper part of the window opening is passed through the ring in sequence, the shading curtain 1 can be lifted up sequentially by pulling up the lifting / lowering cord. Has been. In the present embodiment, only the right edge portion of the ring tape 6 is sewn in the vertical direction with respect to the outer material 5, but of course, both sides may be sewn to the outer material 5.

  The light shielding tape 10f is affixed so as to cover the seam 20 when the ring tape 6 is sewn to the outer surface 5. As will be described later, one half of the light-shielding tape 10f is sandwiched and stitched between the outer material 5 and the ring tape 6, and the remaining half is folded back onto the ring tape 6 and pasted. It has been. Further, since the seam 20 is hidden under the shading tape 10, it is indicated by a dotted line in FIG.

  Next, the configuration of the light shielding tape 10 will be described with reference to FIG. FIG. 4 is a cross-sectional view showing the configuration of the light shielding tape 10. As shown in the figure, the light shielding tape 10 has a four-layer structure. From the top, a polyester outer surface 11, a light shielding layer 12 made of a light shielding film, a back layer 13 made of fluorine-containing polyurethane, An adhesive layer (adhesive layer) 14 made of hot melt is disposed.

  Of course, the structure of the light-shielding tape 10 can be changed as appropriate, and it is only necessary to have a light-shielding layer having a light-shielding function and an adhesive layer to be attached to another member. In addition, the light shielding tape 10 is provided in a state of being wound in a roll shape, and may be used by cutting to a predetermined required length when sewing the light shielding curtain. Further, the light shielding tape 10 is formed with a cut line on the center line for folding the center line about the axis, so that the folding can be easily performed. This cut is made in the surface layer 11.

  The configuration of the light shielding curtain 1 manufactured by the curtain sewing method according to the present embodiment has been described above. Next, the processing procedure when the light shielding tape 10 is attached will be described in detail with reference to the drawings. FIG. 5 is an image diagram schematically showing a state when the light-shielding tape is attached to the seam of the edge portion of the outer material, and shows a state in a horizontal cross section.

  First, when the edge of the outer material 5 is folded and stitched together, as shown in FIG. 5A, the edge of the outer material 5 is folded and one side of the light shielding tape 10 is sandwiched between the folded regions. In the state, the folded portion is sutured. In FIG. 5A, the seam 20 formed by the stitching is indicated by a dotted line. The shading tape 10 is inserted so that the adhesive layer faces upward in the drawing.

  Subsequently, as shown in FIG. 5 (b), the shading tape 10 is folded at the center line, and the remaining half on one side is brought into contact with the upper surface of the folded portion of the outer cover 5 so as to cover the seam 20. As indicated by the arrow inside, thermocompression is performed by pressing with an iron from above. The hot melt of the glue layer 14 is melted by the heat of the iron and then hardens at room temperature, so that the light shielding tape 10 is adhered to the edge of the surface material 5.

  Then, one half of the light shielding tape 10 is sewn to the outer surface 5 while being sandwiched between the folded portions of the outer cover 5, and the other half of the light shielding tape 10 has a seam 20 on the folded portion of the outer cover 5. Bonded and fixed so as to cover. In this way, if the light shielding tape 10 is firmly fixed to the outer surface 5 by stitching and adhesion, it is possible to prevent the light shielding tape 10 from peeling off even if the light shielding curtain is repeatedly raised and lowered.

  Next, a processing procedure for attaching the light shielding tape 10 to the seam of the ring tape 6 will be described with reference to FIG. FIG. 6 is an image diagram schematically showing a state when the light-shielding tape is attached to the seam of the ring tape, and shows a state in a horizontal cross section.

  First, as shown in FIG. 6A, the ring tape 6, the light shielding tape 10, and the surface material 5 are stitched together with one half of the light shielding tape 10 sandwiched between the ring tape 6 and the surface material 5. In FIG. 6A, the seam 20 by this stitching is shown by a dotted line. The light shielding tape 10 is sandwiched so that the adhesive layer faces the upper side (ring tape 6 side) in the figure.

  Subsequently, as shown in FIG. 6 (b), the light shielding tape 10 is folded back at the center line break, and the other half of the one side is ring tape so as to cover the seam 20 appearing on the ring tape 6. In the state of contact from the upper side of 6, as shown by the arrow in the figure, pressing with an iron from the upper side is performed to perform thermocompression bonding.

  As a result, as in the case of light shielding at the edge of the outer surface 5, one half of the light shielding tape 10 is bonded and fixed so as to cover the seam 20 on the ring tape 6, and light leaks from the pinhole of the seam 20. Can be prevented.

As described above in detail, according to the curtain sewing method according to the present embodiment, the light shielding tape is applied to the two cloths to be stitched together (the outer fabrics 5 of the edge turnover portion of the light shielding curtain 10 or the outer fabric 5 and the ring tape 6). 10 are stitched together with the halves on one side overlapped, and then the other side of the light-shielding tape 10 is folded back so as to hide the seam 20, so that the pinhole of the seam 20 by stitching can be reliably shielded from light. The shading tape 10 can be firmly fixed so as not to be peeled off from the seam 20 by sewing and adhesion.

  The embodiment of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention. For example, in the above embodiment, the case where the folded portion of the edge portion of the shade curtain and the seam of the ring tape portion are shielded is described as an example, but the present invention is of various types that need to shield the seam. Needless to say, it is applicable to curtains. Of course, the present invention can also be applied to a seam when a member other than the ring tape is sewn to the curtain. In addition, the present invention is applicable not only to a single-tailored curtain, but also to a curtain in which two or more sheets such as a lining and a surface are bonded.

  Moreover, in the said embodiment, although the contact bonding layer is provided in the light shielding tape, you may make it adhere | attach by putting an adhesive film etc. separately and sticking between light shielding tapes, and when attaching. You may make it apply an adhesive directly.

  Moreover, in the said embodiment, although the one side half of the light-shielding tape is pinched | interposed, if it reaches the position to be stitched, the width to be pinched can be changed as appropriate. Further, the folded width of the light-shielding tape can be appropriately changed as long as the seam portion can be folded and covered. Of course, there may be no break for folding the light shielding tape, and it can be formed at any position.

  Next, a modification of the present embodiment will be described with reference to FIG. FIG. 7 is an image diagram schematically showing a state when the light shielding tape is attached to the seam of the edge portion of the outer cover according to the present modification.

  As shown in the figure, in this modification, the light shielding tape 10 ′ is not sandwiched between the folded outer fabrics 5, but after folding, one side of the light shielding tape 10 ′ is superimposed on the folded portion. So we sew together the three pieces together. Then, after sewing, the other side of the light shielding tape 10 'is folded back, and the adhesive layers of the opposing light shielding tape 10' are bonded together by thermocompression bonding.

  According to this modification, the stability of fixing is slightly inferior because the shading tape is not sandwiched between the two cloths to be sewn, but the pinhole of the seam is firmly secured by the same effect as the above embodiment. And can be shielded from light.
