From this perspective, it is preferable that the material constituting the protrusions is aluminum or an aluminum alloy. This is because these materials are easy to obtain a Vickers hardness of 65 to 100 HV.

  • the predetermined value can be appropriately set according to the required performance, and can be, for example, 90 N.
  • the thickness T 1 of the base is too large, it becomes difficult to penetrate the fabric and difficult to engage with the button, so it is preferable to set it to 0.65 mm or less.
  • the tip of the projection is the part that first penetrates the fabric, it is preferable that the tip is thinner than the base.
  • the thickness T2 of the projection can be appropriately selected depending on the application, but it is generally thinner than the base thickness T1 , for example, 0.37 mm to 0.43 mm.

  • the projection 12 of the button fastening tool 10 is then crimped so as to bend radially outward and then downward along the inner surface 22a of the flange portion 22 supported by the inclined surface 42 of the punch 41, as shown in Figures 5 and 6.
  • Figure 6 shows the state in which the crimping of the projection 12 of the button fastening tool 10 has been completed and the attachment of the female snap button 20 to the fabric 1 has been completed, at which point the descent of the punch 41 stops.

  • the thickness T2 of the tip of the projection is 0.33 mm
  • the height H of the projection is 3.71 mm.
  • the bending strength of the protrusion was measured for each example. Specifically, a special measuring tool was used to apply a force perpendicular to the outer circumference of the protrusion at any position on the tip of the protrusion, and the load value at the specified position was measured. The evaluation results for each example are shown in Table 1.
  • the protrusion 12 of the button fastener 10 was crimped using the procedure shown in Figures 3 to 6.

  • Example 1 the bending strength was 16.57 N and the separation strength was 131.47 N. In Example 1, the bending strength was 14.48 N and the separation strength was 138.02 N. In Example 2, the bending strength was 13.16 N and the separation strength was 143.71 N. In Example 3, the bending strength was 10.25 N and the separation strength was 112.60 N. In Example 4, the bending strength was 12.05 N and the separation strength was 194.38 N. In Example 5, the bending strength was 14.33 N and the separation strength was 90.51 N. In Example 6, the bending strength was 15.35 N and the separation strength was 195.85 N. In Reference Example 2, the bending strength was 6.97 N and the separation strength was 55.58 N.
  • Reference Example 2 can solve the problem of the present invention in that it is easy to attach to the fabric, but Examples 1 to 6 in which the thickness T 1 of the base of the protrusion is in the range of 0.55 mm to 0.65 mm are more preferable in that they have a higher separation strength and are less likely to come off from the fabric. Furthermore, when the height H is in the range of 3.50 mm to 3.91 mm, both separation strength and bending strength are achieved, and it is found to be superior to Comparative Example 1 in which both the button fastener and the female snap button are made of stainless steel.
