Embodiment 1
[0014] Select the bast part of apocynum bast, make it into fiber bundles, add tap water at a mass ratio of 1: 2.5, adjust the pH value to 7 with lime water, add a microbial culture solution with a water ratio of 3% in total, and degumming at 35°C for 4 days. During this period, take out the fiber bundle for observation, and when it is torn into a net by hand, the degumming is over. After removing the degumming waste water, washing with clear water and drying, the technical fiber raw material for textile can be obtained, and the residual glue rate of the fiber raw material is only 0.32%.
Embodiment 2
[0016] Select the bast part of apocynum bast, make it into fiber bundles, add tap water at a mass ratio of 1: 2.5, adjust the pH value to 8 with lime water, add a microbial solution with a water ratio of 4% in the total amount, and incubate at 36°C for 3 days, during which Take out the fiber bundle and observe until it is torn into a net by hand, that is, the degumming is over. The degumming waste water is removed, washed with clear water and dried to obtain a textile fiber raw material with a residual glue rate of 0.29%, which is directly used for spinning.
Embodiment 3
[0018] Select the bast part of Apocynum apocynum, make it into fiber bundles, add tap water at a mass ratio of 1:2.8, adjust the pH value to 6 with citric acid water, add a microbial solution with a water ratio of 5% of the total amount, and incubate at 38°C for 2 days. During this period, take out the fiber bundle and observe that it is torn into a net by hand, that is, the degumming is over. Remove the degumming waste water, wash and dry the raw material with a residual glue rate of 0.2% to the technical fiber raw material for textile.
