Embodiment 1
[0044] A silk mask doped with cellulose nano whiskers, the preparation method of which is as follows:
[0045] (1) The silk raw material was added into water at 95°C for 1 hour, the mass ratio of silk to deionized water was 1:1, and alkali treatment was performed after centrifugal dehydration. The centrifugation is carried out with a flat plate centrifuge, and the centrifugation conditions are as follows: the rotating speed is 3000rpm, and the centrifugation time is 15min. The alkali treatment is specifically: immersing the silk in 80° C. with a mass fraction of 0.1% Na 2 CO 3 In the solution, after reacting for 30 minutes, wash it with 80°C deionized water, and then add 80°C, 0.1% Na 2 CO 3In the solution, react for 30 minutes, repeat once, and wash the obtained silk fiber until it is neutral; wherein the mass ratio of silk to sodium carbonate is 100:1.
[0046] (2) Mix Alealase 2.4L enzyme into the silk fiber obtained in step (1), stir and disperse evenly at a rotating s...
Embodiment 2
[0049] A kind of silk mask containing cellulose nano whiskers, its preparation method is as follows:
[0050] (1) Add silk raw materials into water at 95°C for 3 hours, the mass ratio of silk to deionized water is 1:100, and carry out alkali treatment after centrifugal dehydration. The centrifugation conditions are as follows: the rotation speed is 3000 rpm, and the centrifugation time is 15 minutes. The alkali treatment is specifically: soaking the silk at 85°C with a mass fraction of 10% Na 2 CO 3 In the solution, after reacting for 60 minutes, wash it with 85°C deionized water, and then add 10% Na at 85°C again. 2 CO 3 In the solution, react for 60 minutes, repeat the execution 5 times, and wash the obtained silk fibroin fiber to neutrality. Wherein the mass ratio of silk and sodium carbonate is 100:10.
[0051] (2) Mix Alealase 2.4L enzyme into the silk fiber obtained in step (1), stir and disperse evenly at a rotating speed of 200r / min, and add enzyme at a temperatur...
Embodiment 3
[0054] A kind of silk mask containing cellulose nano whiskers, its preparation method is as follows:
[0055] (1) Add silk raw materials into water at 100°C for 3 hours, the mass ratio of silk to deionized water is 1:50, and carry out alkali treatment after centrifugal dehydration. The centrifugation conditions are as follows: the rotation speed is 3000 rpm, and the centrifugation time is 15 minutes. The alkali treatment is specifically: soaking silk at 90°C with a mass fraction of 5% Na 2 CO 3 In the solution, after reacting for 40 minutes, wash it with 90°C deionized water, and then add 90°C, 5% Na 2 CO 3 In the solution, react for 40 minutes, repeat the execution 10 times, and wash the obtained silk fiber to neutrality; wherein the mass ratio of silk to sodium carbonate is 100:5.
[0056] (2) Mix Alealase 2.4L enzyme into the silk fiber obtained in step (1), stir and disperse evenly at a rotating speed of 1000r / min, and add enzyme at a temperature of 70°C with an enzyme...
