Problems solved by technology

But so far in the prior art, the viscose fiber with antibacterial health care function that has not used plant antibacterial agent-gingko biloba spinning comes out
And how to apply Ginkgo biloba extract as the antibacterial agent used for spinning does not yet have a reasonable, simple and mature production process. Therefore, it is urgent to research and develop a viscose fiber with Ginkgo biloba antibacterial function and its preparation method

Abstract

The invention discloses a viscose fiber with an antibacterial function of ginkgo leaves. The viscose fiber contains at least 80wt% of alpha cellulose and at least 3.5mg/Kg of flavonoids, lactone compounds and organic acid substances; the viscose fiber has the bacteria inhibitive rate of larger than or equal to 92% for staphylococcus aureus, the bacteria inhibitive rate of larger than or equal to 91% for Escherichia coli and the bacteria inhibitive rate of larger than or equal to 81% for candida albicans; the fiber is lasting in antibacterial function and has no any side effects on human bodies. The invention also discloses a preparation method of the viscose fiber with the antibacterial function of ginkgo leaves. The method is reasonable and simple in process, suitable for industrial production and capable of sufficiently exerting the unique advantages of lasting antibacterial function of the ginkgo leaves.

Description

technical field [0001] The invention belongs to the technical field of functional cellulose fibers, and in particular relates to a viscose fiber with ginkgo biloba antibacterial function and a preparation method thereof. Background technique [0002] Existing conventional viscose fiber is regenerated cellulose fiber, and its products have the characteristics of good moisture absorption and air permeability, and are comfortable to wear, but do not possess the antibacterial function of ginkgo biloba. With the improvement of people's living standards and the change of life concept, people pay more and more attention to the health care function of textiles, and hope that the existing viscose textiles can be improved in terms of antibacterial properties and the like. [0003] Ginkgo biloba is the dry leaf of Ginkgo biloba, harvested in autumn when the leaves are still green. The extract extracted from Ginkgo biloba is a good natural antibacterial agent, which has been widely use...
