Title:
HYDROXYLATED ALGINATE FIBER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/252955
Kind Code:
A1
Abstract:
A hydroxylated alginate fiber and a preparation method therefor, belonging to the technical field of polymer materials. The method comprises: pulverizing divalent alginate, adding the pulverized product to a polyvinyl alcohol aqueous solution, and then stirring, deaerating, measuring, coagulating, drawing and shaping to obtain a hydroxylated alginate fiber. By means of the method for pulverizing the divalent alginate, the volume of the divalent alginate is physically reduced, and same is added to the polyvinyl alcohol aqueous solution, so that the hydrogen bond angle between the divalent alginate and the polyvinyl alcohol is small, the bond strength is large, the hydrogen bond force is strong, and the compatibility is increased. The produced fiber has certain physical properties, and the breaking strength of single yarn is ≥16.5 cN/dtex.
