Embodiment 1
[0022] Apocynum degumming process comprises the following steps successively:
[0023] 1) Take apocynum hemp skin and soak it in water for 20 minutes at a bath ratio of 1:25, add 0.5% peptone and 0.9% NaCl to the soaking liquid of the sesame skin, and then place the skin and the soaking liquid at 120°C for 30 minutes ;
[0024] 2) Adjust the pH of the hemp skin and soaking solution after step 1) to 9 with sodium hydroxide solution, and add 5g / L Tween 80, and transfer the microbial seed bacterial solution to adjust the pH with 10% inoculum Cultivate in the hemp skin soaking solution at 28°C and 140rpm for 24h;
[0025] 3) Add 10 g / L of 35% hydrogen peroxide and 5 g / L of 35% sodium silicate to the hemp skin treatment solution in step 2), and keep the temperature at 100° C. for 60 min;
[0026] 4) Transfer the hemp fiber after step 3) to clean water, add hydrochloric acid solution to adjust the pH to 7.0, add catalase 10g / L, keep it under stirring at 28°C for 30min, take out th...

[0034] Apocynum degumming process comprises the following steps successively:
[0035] 1) Take apocynum hemp skin and soak it in water for 30 minutes with a bath ratio of 1:15, add 0.5% peptone and 0.5% NaCl to the soaking liquid of the sesame skin, and then place the skin and the soaking liquid at 120°C for 30 minutes ;
[0036] 2) adjust the pH to 10 with sodium hydroxide solution for the hemp skin and soaking solution after step 1), and add 5g / L penetrant JFC, and transfer the microbial seed bacterial solution to adjust the pH with 10% inoculum Cultivate for 36 hours at 28°C and 140rpm in the hemp skin soaking solution;
[0037] 3) Add 15 g / L of 35% hydrogen peroxide and 10 g / L of 35% sodium silicate to the hemp skin treatment solution in step 2), and keep the temperature at 100° C. for 60 min;
[0038] 4) Transfer the hemp fiber after the treatment in step 3) to clean water, add hydrochloric acid solution to adjust the pH to 7.0, add catalase 15g / L, keep it under stirrin...
Embodiment 3
[0046] Apocynum degumming process comprises the following steps successively:
[0047] 1) Take apocynum hemp skin and soak it in water with a bath ratio of 1:50 for 10-120 minutes, add 1% peptone and 0.9% NaCl to the soaking liquid of the skin, and then put the skin and the soaking liquid at 115°C Keep warm for 30 minutes;
[0048] 2) Adjust the pH of the hemp skin and the soaking solution after step 1) to 11 with sodium hydroxide solution, and add 5g / L penetrant BX, and transfer the microbial seed bacterial solution to the pH adjustment with 15% inoculum Cultivate for 36 hours at 28°C and 140rpm in the hemp skin soaking solution;
[0049] 3) Add 15 g / L of 35% hydrogen peroxide and 10 g / L of 35% sodium silicate to the hemp skin treatment solution in step 2), and keep the temperature at 100° C. for 60 min;
[0050] 4) Transfer the hemp fiber after the treatment in step 3) to clean water, add hydrochloric acid solution to adjust the pH to 8, add catalase 20g / L, keep it warm fo...
