Ultrasonic seaming could soon replace the needle and thread technique with a safer, more efficient technology. In this designed experiment, the Chase FS-90 Ultrasonic Sewing Machine will be compared to the traditional sewing machine. The goal is to examine the sewing quality of textile fabric using ultrasonic methods by finding ideal parameters. The parameters are amplitude, speed, and pressure by using materials, including one thermoplastic fabric, one natural fabric, and low-melting polymer tape. The ultrasonic seam with the best properties will then be compared to the traditional needle and thread seam. The final product will be a designed dress using all ultrasonic seams. The material found to have the best seam properties will be used for the design.
