Embodiment 1
[0016] A dyeing and finishing process for blended knitted fabrics containing protein fibers, comprising the steps of:
[0017] 1) Refining silk cotton in a refining solution mixed with dioctyl iodide succinate sodium salt and soda ash at a ratio of 1:1, heating at 5°C / min to 95°C for 30 minutes, and draining water;
[0018] 2) Add hot water at 70°C, then add 1.5g / L alkyl polyoxyethylene ether and 2g / L sodium hexametaphosphate, heat at 5°C / min to 95°C for 25 minutes, and drain the water;
[0019] 3) Add 1g / ml glacial acetic acid, heat to 60°C for 25 minutes, and drain water;
[0020] 4) Dyeing: Add water and 2g / L sulfonated castor oil in turn, run for 8 minutes, add dye linearly for 50 minutes, heat to 40℃ at 5°C / min, add sodium sulfate linearly for 50 minutes, level dye for 20 minutes, add soda ash linearly for 50 minutes , heat up to 85°C at 5°C / min, keep warm for 15 minutes, and release water;
[0021] 5) Add 1.5g / L glacial acetic acid for pickling;
[0022] 6) Add 1g / L c...
