Abstract: The invention discloses a continuous polyester fiber textile cloth that can be torn into pieces, processing equipment and a processing method. By ultrasonic hot-melting technology, the polyester fiber textile cloth is subjected to the high temperature generated by the high frequency generated by the action of a metal knife mold and an ultrasonic welding head, so that the thread of the loop layers and the base layer are melted in a line to form a thin line melting body that can be torn apart. The knife mold and the ultrasonic welding head are close to each other and resonate to generate heat. When they leave each other, the resonance disappears and the heat decreases, so as to realize the formation and temperature control of a linear high temperature zone.
