Title:
METHOD FOR PREPARING FIBER ADDED WITH QUERCITRIN AND FIBER
Document Type and Number:
WIPO Patent Application WO/2020/252994
Kind Code:
A1
Abstract:
A method for preparing a fiber added with quercitrin and a fiber, which are used for solving the technical problem in the prior art that after rose flowers are treated, petal residues as waste cannot be utilized, and quercitrin can only be added into a medicament to perform its function. The preparation method comprises the following steps: salting fresh rose flowers, and performing distillation and sedimentation centrifugation to obtain wet rose flower residues and an oil-water mixed solution; extracting cellulose from the wet rose flower residues, and separating quercitrin from the oil-water mixed solution at the same time; adding the extracted quercitrin to an ethylene-based polymer; and blending the ethylene-based polymer added with quercitrin and the extracted cellulose by means of a composite fiber spinning method, so as to obtain a finished fiber added with quercitrin. Extracting cellulose from rose flower residues and combining same with quercitrin make the finished fiber has a better physiotherapeutic effect.
