What is the difference between DTY and FDY?

DTY: Drawn textured yarn, also known as polyester low-stretch yarn, it is a finished yarn that is continuously or simultaneously stretched and deformed on a machine.

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

DTY fiber is crimped, FDY fiber is straight.

DTY network yarn: the network yarn refers to the filament in the network nozzle, the filaments are intertwined with each other through the action of the jet airflow to form a periodic network point. Network processing is mostly used for the processing of POY, FDY and DTY. The low-elastic network yarn produced by the combination of network technology and DTY technology has the bulkiness and good elasticity of the textured yarn, and has many periodicity and network points, which improves the filament The compactness saves several processes in textile processing and improves the ability of the tow to pass through the water jet loom.
