[0044] Example 1
[0045] The first step: pretreatment process
[0046] 1. Desizing process:
[0047] Put the cupro-ammonia fiber in the room temperature coiling machine, start to heat up at room temperature, heat up to 40°C, add 2g / L desizing enzyme and run for 10 minutes, add 1g / L penetrant, heat up to 80°C and run for 20 minutes to reach the bath The ratio is 1:20.
[0048] 2. Bleaching process
[0049] Discharge the remaining desizing aid and water in the coiling machine. The first step: add soda ash to adjust the pH to 11, and stir for 20 minutes until uniform; the second step: add 30% hydrogen peroxide 6g / L. Warm up to 40℃, stir for 10min, the third step: add stabilizer 2g / L, stir for 5min until uniform; the fourth step: add detergent 1g / L, stir for 10min, bath ratio 1:20;
[0050] 3. Airflow machine enzyme washing and polishing process
[0051] Add 1 g / L of cellulase and run for 5 minutes; adjust the pH to 4.5 with buffer acid, run for 5 minutes, control the temperature rise at ...

[0068] The first step: pretreatment process
[0069] 1. Desizing process:
[0070] Put the cupro-ammonia fiber in the room temperature coiling machine, start to heat up at room temperature, heat up to 40°C, add 3g / L desizing enzyme to run for 10 minutes, add 2g / L penetrant, heat up to 80°C and run for 20 minutes to reach the bath The ratio is 1:20.
[0071] 2. Bleaching process
[0072] Discharge the remaining desizing aid and water in the coiling machine. The first step: add soda ash to adjust the pH to 11, and stir for 20 minutes until uniform; the second step: add 30% hydrogen peroxide 6g / L. Warm up to 40°C and stir for 10 minutes; Step 3: Add stabilizer 4g / L, stir for 5 minutes, until uniform; Step 4: Add detergent 2g / L, stir for 10 minutes, bath ratio 1:20;
[0073] 3. Airflow machine enzyme washing and polishing process
[0074] Add 1 g / L of cellulase and run for 5 minutes; adjust the pH to 5 with buffer acid, run for 5 minutes, control the temperature rise at...

[0091] Pretreatment process
[0092] 1. Desizing process
[0093] Put the cupro-ammonia fiber in the room temperature coiling machine, start to heat up at room temperature, heat up to 40°C, add 3g / L desizing enzyme to run for 10 minutes, add 2g / L penetrant, heat up to 80°C and run for 20 minutes to reach the bath The ratio is 1:20;
[0094] 2. Bleaching process
[0095] Drain the remaining desizing aids and water in the coiling machine, the first step: add soda ash to adjust the pH to 10.5, stir for 20min until uniform; the second step: add 30% hydrogen peroxide 5g / L, and heat up to 40℃ , Stir for 10min; Step 3: Add stabilizer 3g / L, stir for 5min, until uniform; Step 4: Add detergent 2g / L, stir for 10min, bath ratio 1:20;
[0096] 3. Airflow machine enzyme washing and polishing
[0097] Add 1 g / L of cellulase and run for 5 minutes; adjust the pH to 4.8 with buffer acid, run for 5 minutes, control the temperature rise at 50°C, run for 15 minutes;
