Embodiment 1
[0021] Embodiment 1: The present invention discloses a new dyeing process of polyester air variable yarn, comprising the following steps:
[0022] 1) Loose-type winding process: use a common loose-type winder to wind the high-density straight-tube polyester space-changing yarn to the dyeing cylinder to form a density of 0.35g / cm 3 package yarn;
[0023] 2) Steaming pre-setting: Put the cheese after loose winding into the steam box, vacuumize the box to reach a negative pressure of 145mbar, inject steam into the box and steam for 120 minutes, and the steam pressure is controlled at 0.2 MPa, The steaming temperature is controlled at 130°C, and the cheese is pre-shrunk and shaped, and after steaming, it is kept at 130°C for 20 minutes;
[0024] 3) Loose-type winding process: the package yarn after pre-shrinking and setting is winded again by ordinary loose-type winding machine to a density of 0.35g / cm 3 the cheese;
[0025] 4) Dyeing process: Put the package yarn after loose w...

Embodiment 3
[0043] Embodiment 3: The present invention discloses a new process for dyeing polyester air variable yarn, which includes the following steps:
[0044] 1) Loose-type winding process: use a common loose-type winder to wind the high-density straight-tube polyester space-changing yarn to the dyeing cylinder to form a density of 0.35g / cm 3 package yarn;
[0045] 2) Steaming pre-setting: Put the cheese after loose winding into the steam box, vacuumize the box to reach a negative pressure of 145mbar, inject steam into the box and steam for 130 minutes, and the steam pressure is controlled at 0.15 MPa , the steaming temperature is controlled at 130°C, and the cheese is pre-shrunk and shaped, and after steaming, it is kept at 130°C for 30 minutes;
[0046] 3) Loose-type winding process: the package yarn after pre-shrinking and setting is winded again by ordinary loose-type winding machine to a density of 0.35g / cm 3 the cheese;
[0047] 4) Dyeing process: Put the package yarn after ...
