Ultrasonic-cut serrated 40 square towels are processed using 40KHz ultrasonic cutting technology, with serrated edges and a standard 40cm size. Their main advantages include sealed edges that do not fray, neatly patterned serrations, and precise cutting, suitable for daily use, beauty care, gifts, and more. Detailed information is as follows:

1. Core Definition and Naming

• Definition: Made with 40KHz ultrasonic cutting technology, creating uniform serrated edges. Standard size is 40×40cm, combining practicality and decorative appeal, distinguishing it from traditional heat-cut or blade-cut towels.

• Naming Breakdown:

• Ultrasonic Cutting: Uses 40KHz high-frequency vibration to heat and melt the fabric locally, cutting and sealing the edges simultaneously.

• Serrated Edge: Continuous V-shaped/wave-shaped pattern, with 3-5mm spacing and 2-3mm depth, enhancing visual texture and slip resistance.

• 40 Square Towel: Standard edge length 40cm, suitable for handheld or tabletop placement.
