DTY: Stretch textured yarn. Also known as polyester low elastic yarn, it is the finished yarn after continuous or simultaneous stretching and deformation processing on the machine.

FDY: Fully drawn yarn. It has nothing to do with the production process, but it is widely circulated now. As the code name of one-step spinning and drawing process, low-speed spinning and high-speed drawing and winding can be used. These two processes are completed on a spinning and stretching machine. The production line has low production cost, stable finished product quality, less broken ends and good dyeing uniformity.

DTY fiber is curly and FDY fiber is straight.

Good luck!
