Embodiment 1
[0030] A kind of dyeing process that contains the blended fiber of nylon, comprises the following steps:
[0031] (1) Pre-setting: Pre-setting the fiber through a pre-setting machine. During the pre-setting process, the setting temperature is 158°C, the speed is 10m / min, and the overfeed is 5%;
[0032] (2) Pre-treatment: The pre-formed fiber is pre-treated with a pre-treatment solution, specifically using a softener triethanolamine stearate quaternary ammonium salt 4 g / L, an emulsifier BP 1.5 g / L, and a penetrant JFC 3 g / L, accelerator 1227 1 g / L, soda ash 2 g / L, 60% hydrogen peroxide 2 g / L, treat in a water bath at 25°C for 2 min, the bath ratio is 20:1, and then heat up in the water bath at a rate of 2.5 °C / min, when the temperature rises to 97 °C, keep at this temperature for 30 minutes, then the temperature of the water bath is lowered at a rate of 1.5 °C / min, when the temperature drops to 60 °C, discharge the treated wastewater and reinject clean water can;

Embodiment 3
[0050] A kind of dyeing process that contains the blended fiber of nylon, comprises the following steps:
[0051] (1) Pre-setting: Pre-setting the fiber through a pre-setting machine. During the pre-setting process, the setting temperature is 162°C, the speed is 15m / min, and the overfeed is 10%;
[0052] (2) Pre-treatment: The pre-formed fiber is pre-treated with a pre-treatment liquid, specifically using a softener triethanolamine stearate quaternary ammonium salt 6 g / L, an emulsifier BP 3.5 g / L, and a penetrant BX 4 g / L, accelerator 1227 2 g / L, soda ash 3 g / L, 60% hydrogen peroxide 3 g / L, treat in a water bath at 30°C for 3 min, the bath ratio is 20:1, and then heat up in the water bath at a rate of 3 °C / min, when the temperature rises to 99 °C, keep at this temperature for 35 minutes, then the temperature of the water bath is lowered at a rate of 2.5 °C / min, when the temperature drops to 65 °C, discharge the treated wastewater and reinject clean water can;
