[0013] As a specific embodiment of the above method of the present invention, in step 1, performing a wrinkle-free resin finishing on the dark-dyed garment comprises:

[0014] When the garment is inside out, the permanent-iron resin finishing liquid is evenly sprayed onto the dark-dyed garment using an atomized spray method. During the spraying process, the garment is continuously rotated / tumbled for uniform wetting, controlling the liquid pick-up rate to 50-150%, completing the permanent-iron resin finishing of the dyed garment. Turning the garment inside out refers to turning the garment skin-facing.

[0015] As a specific embodiment of the above method of the present invention, the permanent-ironing resin finishing liquid comprises modified dimethylol dihydroxyethylene, etc. For example, in some embodiments of the present invention, the permanent-ironing resin finishing liquid is ARCHROMA F-AP.

[0016] As a specific embodiment of the method described above in the present invention, wherein, in step 2, the dyed garment after the wrinkle-free resin finishing is pre-baked to control its liquid carrying rate to 10-90%, preferably 10-70%. The present invention does not make specific requirements on the operation and process parameters of the pre-baking, and can be reasonably adjusted according to the actual operation conditions on site, as long as it is guaranteed that the liquid carrying rate of the dyed garment after the wrinkle-free resin finishing can be controlled to 10-90%.
