In recent years ultrasonic seaming that is shown as an alternative method to conventional seaming has been investigated by many researchers. The scope of my thesis was to develop fabric seam using synthetic fabric by an ultrasonic sewing machine. This fabric will be tested for usual seam quality. The methodology that was used is the utilization of the ultrasonic sewing machine. The intended seam was used to sew polyamide fabric to produce Sportswear Using the same fabric, traditional seam with needle and thread was prezared. Seam strength, sewing elongation and appearance were measured using ASTM standard methods. Knowledge generated in this project will be presented in the thesis. Successful techniques will provide an alternative method of manufacturing clothing. This has an environmental effect in that it reduces the significant amount of waste that we produce every year in garment manufacturing.
