Embodiment 1
[0031] The active one-bath dyeing process of wool and flax blended yarn in this embodiment comprises the following steps (the process flow chart is as follows: Figure 1-2 shown):
[0032] Step 1: Yarn pretreatment, add water at room temperature, raise the temperature of the water to 50 degrees Celsius, soak the yarn in water for 10 minutes;
[0033] Step 2: Yarn dyeing, put sodium sulfate and leveling agent into the water in step 1, stir the solution evenly and run it for 10 minutes, raise the temperature to 60 degrees Celsius at a heating rate of 0.7℃ / min, and add Dye, soak in heat for 30 minutes, then add soda ash step by step to fix the color for 60 minutes, and discharge the waste liquid after fixing the color;
[0034] Wherein the leveling agent is Albegal B-LV, and its consumption is 2% of yarn weight, and the consumption of described sodium sulfate is 50g / L, and described dyestuff is cotton reactive dyestuff, and the consumption of described dyestuff is yarn weight. ...
