Description

technical field

[0001] The invention relates to the technical field of ultrasonic sewing, in particular to a device for sewing shirts using ultrasonic technology and a sewing method thereof. Background technique

[0002] China is the world's largest garment consumer and producer, and China is also the world's largest garment production and processing base. In recent years, China's garment industry has developed greatly, and the development of the garment industry has greatly promoted the development of China's national economy. .

[0003] Ultrasonic sewing machine uses ultrasonic vibration to generate energy, cuts the fabric in overlapping style and automatically fuses the edges of the fabric, and completes the butterfly-shaped seamless joint with adhesive tape bonding. Ultrasonic sewing machines can complete all curved surface welding that hot press machines are not capable of, such as armholes, princess lines, crotch seams, etc. It has the advantages of no needle holes, g...
