Abstract

The invention belongs to the technical field of high-molecular chemical material, and relates to a sodium alginate-cuttlebone-hairyvein agrimony extract product blend fiber and a preparation method thereof. The sodium alginate-cuttlebone-hairyvein agrimony extract product blend fiber comprises, by weight, 70 to 82% of sodium alginate, 12 to 20% of cuttlebone, and 6 to 10% of hairyvein agrimony extract product. According to the preparation method, a cuttlebone ultrafine powder slurry, a hairyvein agrimony extract product solution, and a sodium alginate spinning solution are fully mixed, and an obtained mixture is allowed to stand and deaerate so as to obtain a heterogeneous mixed spinning solution; and the sodium alginate-cuttlebone-hairyvein agrimony extract product blend fiber is obtained via spinning. The sodium alginate-cuttlebone-hairyvein agrimony extract product blend fiber is capable of stopping bleeding with high efficiency, astringing dampness and sore, and resisting bacteria; possesses excellent liquid absorptivity and biological activity; is non-toxic and harmless; is high in security; is biodegradable; and possesses a promising application prospect in the fields of medical gauze, hemostatic dressing, cosmetics, and hygienic products.

Description

technical field [0001] The invention belongs to the technical field of macromolecular chemical materials, and in particular relates to a sodium alginate blended fiber of seaweed and octopus Agrimony extract and a preparation method thereof. Background technique [0002] Chinese patent CN100457989C discloses a kind of preparation method of high strength alginic acid / gelatin blended fiber, the blended spinning solution of sodium alginate and gelatin is passed through and Ca 2+ The alginic acid / gelatin blend fiber can be prepared by cross-linking divalent metal ions and the polyelectrolyte effect under acidic conditions, which can increase the cross-linking degree of the fiber, increase the breaking strength of the fiber, and improve the physical properties of the alginic acid / gelatin blend fiber. Mechanical properties, can be used to manufacture non-woven fabrics such as medical gauze, dressings and other medical materials. [0003] Chinese patent CN1332081C discloses a kind ...
