Abstract

The invention discloses a bionic high-quality integrated degumming method of A. venetum L. fiber. The bionic high-quality integrated degumming method comprises screening of alkali-resistant bacteria, and degumming of A. venetum L. fiber. According to the step of screening of the alkali-resistant bacteria, soil bacteria obtained from orchards are subjected to plate streaking separation; separated bacteria are subjected to preliminary screening with A. venetum L. fiber powder; bacteria strains obtained via preliminary screening are subjected to repeated mutagenesis, secondary screening, and subcultring with an alkaline medium so as to obtain the alkali-resistant bacteria; an A. venetum L. bast fiber alkaline fermentation broth containing additional carbon resources is inoculated with the alkali-resistant bacteria, and then fermentation is carried out; after fermentation, the A. venetum L. bast fiber is subjected to further composite processing, acid modulation, and water washing so as to obtain A. venetum L. fiber. According to the bionic high-quality integrated degumming method, the advantages of physical, chemical, and biological processing are adopted; bionic theory is adopted; the clean high-efficiency integrated degumming method is established; the obtained A. venetum L. fiber is tidy, is excellent in spinnability, and possesses antibacterial activity; and anti-ultraviolet properties are maintained preferably.

Description

technical field [0001] The invention relates to a degumming processing method of hemp fiber, in particular to a degumming processing method of apocynum fiber, and belongs to the field of hemp fiber textile processing. [0002] technical background [0003] Apocynum is a characteristic plant resource in my country. It is not only a traditional medicinal plant, but also a source of excellent biomass fiber. In addition to the good hygroscopic properties of general cellulose fibers, apocynum fiber also has functions such as antibacterial, anti-ultraviolet and far-infrared emission, and is a natural functional fiber. [0004] Compared with traditional hemp fibers such as ramie and flax, the research on apocynum weaving technology started late, and there are still some key technologies in the processing link that have yet to be broken through. Like traditional hemp fiber, apocynum fiber also belongs to bast fiber, and degumming is the primary link in the processing process of apoc...
