The invention discloses a refined processing method of apocynum venetum fiber. The refined processing method comprises steps as follows: wetting activation of apocynum venetum bast, beating into cakes and caging, directional catalytic oxidation, chemical degumming and postprocessing, wherein after the apocynum venetum bast is subjected to wetting activation with organic amine solvents, lignin, pectin and hemicellulose are subjected to the directional catalytic oxidation with a ferrite solution and an activator. A series of technological means including wetting activation processing, the directional catalytic oxidation and the like are organically combined, so that the refined processing method of the apocynum venetum fiber has the characteristics that the degumming effect is good, and a finished apocynum venetum fiber product is good in fineness, length, strength and other indexes, excellent in quality, good in spinnability and the like; besides, the consumption of chemicals during processing is low, the environmental protection pressure is low, and the technology is simple to control; the consumption of utilities such as water, electricity, gas and the like is low, the efficiency is high, and the refined processing method is applicable to industrial production. |
