Example Embodiment
[0028] Example 1
[0029] A polyester chiffon printing and dyeing process, including pre-treatment, dyeing treatment and post-treatment. The specific dyeing treatment is: putting polyester chiffon in a low-concentration dyeing solution at room temperature for 40 minutes, taking out the polyester chiffon and putting it directly into the temperature Dyeing for 60 minutes in a high-concentration dye solution at 85℃. After the high-concentration dye solution is naturally cooled, take out the polyester chiffon to complete the dyeing; the mass ratio of polyester chiffon and the low-concentration dye solution is 1:30; The pH value of the solution is 6.5; the mass ratio of polyester chiffon and the high concentration dye solution is 1:40; the pH value of the high concentration dye solution is 4.5;
[0030] The specific post-treatment is: drying the dyed polyester chiffon, adding octadecyl dimethyl tertiary amine with a concentration of 3.33g / L, polyether modified silicone oil with a concen...
