The turquoise blue polyester fabric prepared in the example 1 is shown in fig. 1, and the picture shows that the fabric is basically flat, has no wrinkles and is dyed uniformly. The fabric of comparative example 1 appeared very wrinkled and the process was essentially not feasible without retaining the photograph. The turquoise blue polyester fabric prepared in the comparative example 2 is shown in fig. 2, and the part circled in fig. 2 is willing to see obvious color spots and slight wrinkles.

As can be seen from the data in table 1 and the condition of the fabric, the color fastness of example 1 is obviously improved compared with that of comparative example 1, and the fabric in comparative example 1 has more wrinkles from the basic condition of the fabric, which is probably caused by the fact that the maximum dyeing temperature in the dyeing process is too high and the holding time is over; in the case of comparative example 2, the wrinkles were significantly reduced as compared with comparative example 1, but the problem of color spots occurred, which is probably due to the use of too low dyeing temperature, short holding time, and too high residual stress of the cloth, causing color spots to occur. On the whole, compared with comparative examples 1 and 2, in example 1, the condition after the cloth is dyed is obviously better, and the color fastness is also improved, which shows that the dyeing effect of the polyester turquoise blue can be improved by adopting the process of pre-shrinking, increasing the highest dyeing temperature and prolonging the dyeing time in the application.
