Ultrasonic seaming has become an important issue in recent years due to its various features. In this study, waterproof polyester knitted fabrics with polyurethane coating were used and the bursting strength, bending property and water permeability property of ultrasonic seaming were examined by changing various parameters. Besides, the ultrasonic seaming method was compared to conventional seaming and adhesive tape application. It is observed that there were high water permeability values generally in ultrasonic seaming and also fabrics with no water penetration were seen in this method, although, in some ultrasonic seaming parameters, values are lower than adhesive tape sealed ones. On the other hand, the bursting strength values of the ultrasonically sewn fabrics are found to be comparable to conventional seam and sealing adhesive tape when the optimum seaming parameters are determined. Also, it can be said that for the bending property according to increasing bending length values in this method compared with the others, ultrasonic seaming may find more usage areas where fabric stiffness is more advantageous. It has been observed that it is important to determine the fabric and ultrasonic sewing parameters according to the required performance property.

超声波接缝由于其各种特点，近年来已成为一个重要的问题。在这项研究中，使用带有聚氨酯涂层的防水涤纶针织物，通过改变各种参数来检测超声波缝合的爆破强度、弯曲性能和透水性。此外，将超声波缝合方法与传统缝合和胶带应用进行了比较。据观察，超声波接缝通常具有较高的透水性值，并且在该方法中也观察到没有渗水的织物，尽管在某些超声波接缝参数中，该值低于胶带密封的值。另一方面，当确定最佳缝合参数时，发现超声波缝合织物的破裂强度值可与传统的缝合和密封胶带相媲美。此外，可以说，与其他方法相比，根据这种方法中弯曲长度值增加的弯曲性能，超声波接缝可以找到更多的使用领域，其中织物刚度更有利。据观察，根据所需的性能特性确定织物和超声波缝纫参数非常重要。
