  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a configuration diagram illustrating a configuration of a patchwork-like fabric 30 according to the first embodiment of the present invention.

  As shown in FIG. 1, the patchwork-like fabric 30 is composed of a plurality of pieces of cloth 41 to 47 constituting the patchwork P and a base fabric 50 slightly larger than the size of the patchwork P. Yes.

  The cloth pieces 41 to 47 are cloth pieces that are cut into the same shape as that shown in FIG. 1, and are positioned on both sides of the boundary line L so as to follow the boundary line L constituting the pattern of the patchwork P. For example, the cloth piece 43 and the cloth piece 47 are disposed so that there is no gap so that no gap is formed between the two cloth pieces.

  Each of the cloth pieces 41 to 47 is stitched to the base cloth 50 by the straight stitch A so as to follow the outer periphery of each shape.

  Further, the two pieces of cloth positioned on both sides of the boundary line L and the fabric 50 for the base are stitched together by a staggered stitch B that straddles the boundary line L.

  Here, in the first embodiment, as shown in FIG. 1, the stitches of the staggered stitch B are configured to be positioned on or near the straight line formed by the straight stitch A, and the boundary line L The straight stitches A formed on both sides of the frame are inconspicuous.

  The reason why the two pieces of fabric positioned on both sides of the boundary line L constituting the pattern of the patchwork P are sewn to the base fabric 50 by the straight stitch A and the staggered stitch B is as follows. In the case of washing the first embodiment, when the base fabric 50 is sewn only by the straight stitch A, a gap is generated between two adjacent pieces of fabric without any gap so that the base fabric 50 can be seen. This is because when the stitching stitch B is stitched to the underlying fabric 50 alone, the position of the boundary line L constituting the pattern of the patchwork P is shifted from the original position. .

  As described above, since the cloth pieces 41 to 47 constituting the patchwork-like fabric 30 according to the first embodiment are stitched together with the base fabric 50 by the straight stitch A and the staggered stitch B, this first embodiment. The pattern of the patchwork P does not change even after washing.

  Next, the manufacturing method of Example 1 configured as described above will be described with reference to the drawings.

  In the first embodiment, patchwork to be manufactured can be determined and converted into data on a computer, and can be manufactured using a machine based on the data. When the patchwork to be manufactured is determined and converted into data on this computer, the work is performed using a CAD system in the first embodiment.

  First, as shown in FIG. 2A, the computer C is started up and the monitor M is used to determine the size of the patchwork to be manufactured and the boundary line L that constitutes the pattern of the patchwork (FIG. 2). (See (b)).

  When the position of the boundary line L constituting the pattern of the patchwork to be manufactured is determined as shown in FIG. 3, next, the patterns 41a to 47a of the cloth pieces 41 to 47 constituting the patchwork are designated ( (See FIG. 4 (a)).

  As described above, the patchwork P to be manufactured is determined as shown in FIG. 4B, and is converted into data and stored.

  Next, the following operations are performed using data stored by computer C as data.

  First, each of the small cloth pieces 41 to 47 constituting the patchwork P is cut out from the cloth as the respective materials having the patterns 41a to 47a. The cutting work of the cloth pieces 41 to 47 is performed using an automatic cutting machine (including a laser cutting machine) based on the stored data.

  As described above, the fabric pieces 41 to 47 constituting the patchwork P are manufactured as shown in FIG.

  Next, as shown in FIG. 5B, the cloth pieces 41 to 47 are placed on the base fabric 50 without any gap so as to be the same pattern as the pattern of the patchwork P to be manufactured.

  As shown in FIG. 1, the cloth pieces 41 to 47 placed on the base fabric 50 as described above are automatically stitched with the straight stitches A and A as shown in FIG. The work is finished by fixing the base fabric 50 with the staggered stitch B.

  The patchwork-like fabric 30 shown in FIG. 1 manufactured in this way can be used as a material for shirts and bags in the same way as patchwork for handicrafts. Will not change.
