摘要：
Technological capabilities of sutural ultrasonic welding of synthetic fabrics are considered. Experiments on welding mylar fabric are made. Key parameters of the mode of sutural ultrasonic welding of fabrics which significantly influence the speed of achievement of the maximum temperatures in a zone of a weld joint are determined, defining intensity of a warming up, and, therefore, and welding process productivity.The analysis of the thermal mode of ultrasonic welding of synthetic fabrics and kinetics of formation of a weld joint is carried out. It is suggested that a warmth source at ultrasonic welding of mylar fabrics are hysteresis losses.
