Both elastic limit and yield strength are used to measure the strength of metal materials and their similarities and differences.
The cutting process of fabrics is generally divided into cold cutting and thermal cutting, both of which have certain limitations. Compared to cold cutting, the edges of the cut edge are fused after the thermoplastic material has been cut using ultrasonic fabric cutting; Compared with the thermal cutting process, the use of ultrasonic cutting can make the edge of the fabric being cut very soft and avoid excessive edge thickening due to melt shrinkage. Since the ultrasonic waves are heated from the inside of the fabric, there is no fabric yellowing. Since the ultrasonic waves are heated from the inside of the material, there is no fabric yellowing.
