WOS: 000400278900008In this study, the seam tensile properties of the ultrasonically bonded nonwoven fabrics were investigated and the effects of the fabric type, roller type and sewing speed on the seam tensile properties of the samples were studied. It was deduced that fabric type, roller type and sewing speed have statistically significant effect on the seam tensile properties of the nonwoven fabrics. The experimental results indicate that, the tensile strength of the seams made with made with the engraving roller 4 mm wide point and 25 dm/min speed is the highest, and with the engraving roller 9 mm wide point and 45 dm/min is the lowest
