The machine can process POY filament (polyester preorientation filament) into DTY POLYESTER elastic filament with low elastic energy by stretching and false twist deformation, and can be equipped with interlaced yarn processing for optional function.

In addition to the breaking strength of ordinary polyester yarn, the processed twist yarn has the characteristics of high elastic modulus, excellent thermal setting, good resilience, heat resistance, strong corrosion resistance, easy to wash and dry, but also has the characteristics of high swelling, good heat insulation, comfortable feel, soft luster and so on.
