Embodiment 1
[0031] Embodiment 1: the preparation of subdivision feather fiber
[0032] (1) Wash the chicken feathers with clear water, then soak them in deionized water for 2 hours, and then dry them in an oven at 40°C;
[0033] (2) Slimming treatment of chicken feathers: add 0.45g calcium chloride and 3g urea into 30g water respectively, stir and dissolve until the solution is clear, add 0.9g ammonia water (concentration is 25%) and stir evenly; then add 0.5g chicken feathers Put it into the above mixed solution, treat it in a water bath constant temperature oscillator at 60°C for 2 hours, and keep stirring at 180r / min during this period, then take it out and clean it with deionized water, dry it in an oven at 30°C, and obtain finely divided Feather fiber.
[0034] The feather fiber obtained by the above method has obvious fibrillation, and the average diameter of a single fiber after fiber separation is 1.5-3 μm, and the length is 65-80 μm; figure 1 , figure 2 It is the electron mic...
Embodiment 2
[0035] Embodiment 2: the preparation of subdivision feather fiber
[0036] (1) Wash the chicken feathers with clear water, then soak them in deionized water for 1 hour, and then dry them in an oven at 40°C;
[0037] (2) Slimming treatment of chicken feathers: add 0.3g calcium chloride and 2g urea into 30g water respectively, stir and dissolve until the solution is clear, add 0.75g ammonia water (concentration is 25%) and stir evenly; then add 0.5g chicken feathers Put it into the above mixed solution, treat it in a water bath constant temperature oscillator at 60°C for 2 hours, and keep stirring at 150r / min during this period, then take it out and clean it with deionized water, dry it in an oven at 30°C, and get finely divided Feather fiber.
Embodiment 3
[0038] Embodiment 3: the preparation of finely divided feather fiber
[0039] (1) Wash the chicken feathers with clear water, then soak them in deionized water for 2 hours, and then dry them in an oven at 40°C;
[0040] (2) Slimming treatment of chicken feathers: add 0.6g calcium chloride and 4g urea into 30g water respectively, stir and dissolve until the solution is clear, add 1g ammonia water (concentration is 25%) and stir evenly; then put 0.5g chicken feathers Put it into the above mixed solution, treat it in a water bath constant temperature oscillator at 60°C for 2 hours, and keep stirring at 200r / min during this period, then take it out and clean it with deionized water, and dry it in an oven at 40°C to obtain finely divided chicken feathers fiber.
