  • Degradable and absorbable hemostatic fiber material, preparation method therefor, and hemostatic fiber article thereof
    Patent number: 11369713
    Abstract: A degradable and absorbable hemostatic fiber material, a preparation method therefor, and a hemostatic fiber article thereof. The carboxylation degree of the hemostatic fiber material is 10-25%, and the polymerization degree of the hemostatic fiber material is 10-250. The hemostatic fiber material comprises fiber filaments, the linear density of the fiber filament being 0.8-4.5 dtex, and the dry strength of the fiber filament being 10-150 cN/tex. The degradable and absorbable hemostatic fiber material has a higher carboxylation degree and a lower polymerization degree, while the strength and completeness of the fiber filament can be well maintained, such that the hemostatic effect is better and the hemostasis is faster. Further, the hemostatic fiber material can be degraded and absorbed, and thus is safer.
