The dyeing process was the same as in example 1.
Comparative example 2
Placing the polyester fabric after being matched with a cylinder for 12 hours, then carrying out open-width water washing, after water washing, carrying out pre-shaping, hemming after pre-shaping, dyeing after hemming, and obtaining the turquoise blue polyester fabric after the dyeing is finished, carrying out open-width fabric finishing, final shaping for the first time and rolling.

The turquoise blue polyester fabric prepared in the example 1 is shown in fig. 1, and the fabric is basically flat, has no wrinkles and is uniformly dyed from the picture. The cloth of comparative example 1 had very many wrinkles, and the process was not substantially feasible, and no photograph was left. The turquoise blue polyester fabric prepared in comparative example 2 is shown in fig. 2, and it is desirable to see that there are obvious color spots and slight wrinkles from the circled portion in fig. 2.
The fabrics of example 1 and comparative examples 1 to 2 were tested for basic fabric conditions and color fastness, and the results are shown in table 1.
Wherein:
rubbing fastness-wetting was performed according to ISO 105-X12.
Rubbing fastness-drying was performed according to ISO 105-X12.
Light fastness was carried out according to ISO 105-B02.
Soaping fastness-acetic acid staining was performed according to ISO 105-C06.
Perspiration fastness- -acetic acid staining was performed according to ISO 105-E04.
As can be seen from the data and the fabric conditions in table 1, the color fastness of example 1 is significantly improved compared with that of comparative example 1, and the fabric of comparative example 1 is more wrinkled from the basic condition of the fabric, which may be caused by the fact that the highest dyeing temperature is too high during dyeing and the heat preservation time is caused; in the case of comparative example 2, the wrinkles are significantly reduced as compared with comparative example 1, but the color stain is generated, which is probably due to the fact that the dyeing temperature is too low, the heat-preserving time is short, and the residual stress of the cloth is too high, thereby causing the color stain to appear. Overall, example 1 showed significantly better post-dyeing conditions and improved color fastness compared to comparative examples 1 and 2, demonstrating that the dyeing effect of the terylen turquoise blue can be improved by adopting the process of preshrinking, increasing the maximum dyeing temperature and prolonging the dyeing time.

The turquoise blue polyester fabric prepared in examples 2-5 has no crease and color spot, and the overall fabric condition is good.
As can be seen from the data in Table 2, the color fastness of examples 2-5 is basically between 4-4.5, and compared with the color fastness of example 1, the performance of the dye auxiliary agent is slightly reduced, which indicates that the dye auxiliary agent has a synergistic effect and is beneficial to improving the color fastness of the cloth.
