These false twist texturing machines process polyester POY into low-stretch DTY, while also allowing spandex to be combined with the DTY directly on the machine. This means the two yarns can be brought together during production instead of being processed separately.

An air nozzle is used to combine the spandex yarn with the textured DTY, which allows texturing and spandex interlaced yarn formation to be completed in one process. This helps simplify production and makes the line suitable for yarns that require both texturing and spandex combination. A double W2 roller structure is included to improve interlacing quality and help maintain better finished yarn quality. To match different factory layouts, customers can choose either a fixed or a rotating creel.
