Problems solved by technology

[0002] At present, in order to process natural hemp bast fibers into fiber products with high spinnability, the generally used production processes of hemp degumming and bleaching, such as pickling, alkali boiling, chlorine bleaching, and hydrogen peroxide rebleaching, are due to the presence of silicon in the formula. Sodium peroxide causes the oxidation of hydrogen peroxide to be unstable, so hydrogen peroxide stabilizers are commonly used in formulas, but under high-concentration caustic soda conditions, there is still the problem of unstable hydrogen peroxide
[0003] In addition, the chlorine bleaching process commonly used in hemp fiber can produce toxic dioxins that pollute the human body and the environment; while sodium silicate is used in the degumming and bleaching process, the silica scale produced by sodium silicate adheres to equipment and fibers On the other hand, it makes the hemp fiber feel stiff and poor in spinnability, and has high requirements for the hardness value of the water quality of the production water, and the whiteness, brightness and strength of the hemp fiber after treatment are poor.
