Machine Features´╝Ü
1.DX321F adoptes servo system, inverter, PLC, touch screen and microcomputer control synchronous system.
2.Suits for filament yarn TFO twisting and reverse TFO twisting for DX268V winding up yarn, its finished yarn package weight can reach to 4kg big each, and twisted yarn no knotting and no no oil-stained yarn, provides high quality soft cones directly to cone dyeing.
3.Energy saving design, adoptes two main motors to drive, which not only solved belt uneven tension problem, also declined energy consumption.
4.DX321F adoptes servo system, compared to traditonal gearbox system, servo system has simple structure, no pollution, less noise, easy maintenance, various shaping technology, and better yarn shaping and machine running stabilization.
5.All the high quality parts composed the excellent yarn path, minimized yarn damage duiring its processing and much better suitable for high quailty yarn production request.
6.Based on features of filament yarn, we did many modifications to DX321F, and provide low energy consumption, less manpower requirement and exclusive machinery to replace traditional compound twisting machine at certain level.
7.Can be using as secondery TFO in two times twisting (S and Z) process.
