[0023] Example 1
[0024] A method for synthesizing grafted lysine viscose fiber, the specific process steps are as follows:
[0025] (1) Preparation of purified viscose fiber
[0026] According to the volume ratio of the mass of commercially available viscose fiber to the sodium hydroxide solution with a concentration of 0.5% by mass, the volume ratio is 1:30 (kg / L), and the commercially available viscose fiber is dispersed at a concentration of 0.5% by mass. In the sodium hydroxide solution, the temperature was raised to 80°C, treated for 0.5h and placed in a three-foot centrifuge, centrifuged at a speed of 2000r / min for 10min, and the centrifugal fluid and the centrifuged viscose fiber were collected separately. The collected centrifugal viscose fibers were washed with purified water at a centrifugal speed of 2000 r / min until the pH of the washing centrifugal liquid was 7.0. Separately collect and wash centrifugal viscose fibers and washing centrifugal fluid. For the collected w...

[0036] A method for synthesizing grafted lysine viscose fiber, the specific process steps are as follows:
[0037] (1) Preparation of purified viscose fiber
[0038] According to the ratio of 1:45 (kg / L) between the mass of commercially available viscose fiber and the sodium hydroxide solution with a concentration of 0.8% by mass, the commercially available viscose fiber was dispersed at a concentration of 0.8% by mass. In the sodium hydroxide solution, the temperature was raised to 85°C, treated for 1.0h, placed in a three-foot centrifuge, centrifuged at a speed of 3000r / min for 15min, and collected the centrifugal fluid and centrifuged viscose fibers. The collected centrifugal viscose fibers were washed with purified water at a centrifugal speed of 3000 r / min until the pH of the washing centrifugal liquid was 7.5. Separately collect and wash centrifugal viscose fibers and washing centrifugal fluid. For the collected washing centrifugal viscose fibers, purified ...

[0048] A method for synthesizing grafted lysine viscose fiber, the specific process steps are as follows:
[0049] (1) Preparation of purified viscose fiber
[0050] According to the ratio of the mass of commercially available viscose fiber to the sodium hydroxide solution with a mass percentage of 1.0% by volume ratio of 1:60 (kg / L), the commercially available viscose fiber was dispersed at a mass percentage of 1.0%. In the sodium hydroxide solution, the temperature was raised to 90°C, treated for 1.5h, placed in a three-foot centrifuge, centrifuged at a speed of 4000r / min for 20min, and the centrifugal fluid and the centrifuged viscose fiber were collected separately. The collected centrifugal viscose fibers were washed with purified water at a centrifugal speed of 4000 r / min until the pH of the washing centrifugal liquid was 8.0. Separately collect and wash centrifugal viscose fibers and washing centrifugal fluid. For the collected washing centrifugal viscose ...
