The fabric is embossed along the cutting line with stainless steel embossing roll first and then cut along the embossed cutting line with ultrasonic cutter. Because the cutting line is embossed, the density of the embossed portion becomes higher. Consequently, the lint of the cutting edge is significantly fewer.

First, the ultrasonic fabric edge pressing presses an edge with its stainless steel embossing roll , then cuts the fabric along the pressed line with the ultrasonic cutting, because the cut line has been embossed , so the density of this part is higher, consequently, the lint of the cut edge is significantly fewer than before.
