Embodiment 1
[0022] A process for sand-washing and dyeing environmentally friendly polyester fabrics, comprising the following steps:
[0023] A. Pour soda ash and softener into the industrial washing machine, then add water to make the concentration of soda ash 10g / L and softener 0.3g / L, then put the polyester fabric into the industrial washing machine with a liquor ratio of 1 : 45, stirred 12min at room temperature;
[0024] B. Add vegetable dyes and pH buffering agents into the industrial washing machine, stir evenly at room temperature and adjust the pH value of the system to 7-8, then add 1.5% mordant and sandstone, heat up to 65°C and continue stirring for 25 minutes;
[0025] C. After taking out the fabric, soak it in an acidic solution with a pH value of 5.5-6.2 for 12 minutes;
[0026] D. Dry and iron according to conventional methods to form finished products.
[0027] The softening agent in the step A is a terpolymerized modified silicone oil.
[0028] The plant dyes in the s...
