Embodiment 1
[0029] A preparation method of feather protein regenerated cellulose fiber, comprising the following steps:
[0030] Step 1, preparation of viscose spinning stock solution: the raw material is cotton pulp with a polymerization degree of 500-600, and its methyl fiber content is greater than 90%, and the glue is made according to the following process route:
[0031]
[0032] Gained viscose spinning solution methyl fiber content is 9.0%, and NaOH mass fraction is 6.1, and viscosity is (falling ball method) 59s, and maturity is (10%NH 4 Cl) 8.8 mL.
[0033] Step 2, prepare the feather protein solution: in the reaction kettle, pulverize the down and add it to a 5wt.% NaOH solution, the quality of the down is 5% of the mass of the NaOH solution, soak it for 1 hour at 90°C, and then add the velvet to the solution The mass percentage of down is 0.5% keratinase, the pH of the solution is adjusted to 7.5-8.0 with acetic acid, then the temperature is raised to 50-60° C., the reactio...

[0038] A preparation method of feather protein regenerated cellulose fiber, comprising the following steps:
[0039] Step 1, preparation of viscose spinning stock solution: the raw material is cotton pulp with a polymerization degree of 500-600, and its methyl fiber content is greater than 90%, and the glue is made according to the following process route:
[0040]
[0041] Gained viscose spinning solution methyl fiber content is 8.8%, and NaOH mass fraction is 5.9, and viscosity is (falling ball method) 62s, degree of maturity is (10%NH 4 Cl) 8.7 mL.
[0042] Step 2, prepare the feather protein solution: in the reaction kettle, pulverize the down and add it to 8wt.% NaOH solution, the quality of the down is 8% of that of the NaOH solution, soak it for 1 hour at 90°C, and then add the velvet to the solution The keratinase with a weight percentage of 0.8% of down feathers is used to adjust the pH of the solution to 7.5-8.0 with acetic acid, then the temperature is raised to 5...
