[0040] Example 1
[0041] A dyeing process of real silk fabric includes the following steps:
[0042] (1) Pre-treatment: Pre-treatment of chemical fiber, specifically: urea 1g / L, phosphorus-free neutral deoiling spirit TF-104M 4.5 g / L, sodium dodecylbenzene sulfonate 1 g / L, 60 % Hydrogen peroxide 2 g / L, oxidizing desizing agent OS 0.8 g / L, treated in a 30℃ water bath for 2-3 min, with a bath ratio of 20:1, and then heated in the water bath at a rate of 2.5℃ / min, when the temperature rises After reaching 90℃, keep it at this temperature for 30-40min, and then the temperature of the water bath will be lowered at a rate of 1.5℃ / min. When the temperature drops to 60℃, drain the treated wastewater, and then re-inject clean water and rinse at room temperature. The lotion is neutral, and finally let it dry;
[0043] (2) Predetermined type: the chemical fiber is pre-formed through a pre-formed machine. The pre-formation temperature is 160℃, the vehicle speed is 20m / min, and the overfeed is...

[0057] A dyeing process of real silk fabric includes the following steps:
[0058] (1) Pre-treatment: Pre-treatment of chemical fiber, specifically: urea 1.2g / L, non-phosphorus neutral deoiling spirit TF-104M 5 g / L, sodium dodecylbenzene sulfonate 1.2 g / L, 60% hydrogen peroxide 2.5 g / L, oxidizing desizing agent OS 1g / L, treat in a 30℃ water bath for 2-3 min, bath ratio is 20:1, then the water bath is heated, the heating rate is 2.5℃ / min, when the temperature rises After reaching 90°C, keep it at this temperature for 35 minutes, and then the temperature of the water bath is cooled at a rate of 1.5°C / min. When the temperature drops to 60°C, drain the treated wastewater, and then re-inject clean water to rinse at room temperature until the lotion For neutral, let dry at last;
[0059] (2) Pre-formation: the chemical fiber is pre-formed through a pre-formation machine. The pre-formation temperature is 165°C, the vehicle speed is 25m / min, and the overfeed is 8%;

[0073] A dyeing process of real silk fabric includes the following steps:
[0074] (1) Pre-treatment: Pre-treatment of chemical fiber, specifically: urea 1.5g / L, non-phosphorus neutral oil-free spirit TF-104M 5.5 g / L, sodium dodecylbenzene sulfonate 1.5 g / L, 60% hydrogen peroxide 3 g / L, oxidizing desizing agent OS 1.2 g / L, treat it in a 30℃ water bath for 2-3 min, with a bath ratio of 20:1, and then heat up in the water bath at a rate of 2.5℃ / min. After rising to 90°C, keep it at this temperature for 40 minutes, and then the temperature of the water bath is cooled at a rate of 1.5°C / min. When the temperature drops to 60°C, drain the treated wastewater, and then re-inject fresh water and rinse at room temperature until washing The liquid is neutral, and finally dry;
[0075] (2) Predetermined type: the chemical fiber is pre-formed through a pre-former. The pre-formation temperature is 170°C, the vehicle speed is 30m / min, and the overfeed is 10%;
