The invention provides an antibacterial hemostatic non-woven cotton and a preparation method thereof. In the preparation method of the antibacterial hemostatic non-woven cotton, firstly, the sodium alginate and the dopamine are subjected to amidation reaction to obtain a polymer, then the polymer is used for modifying polylactic acid non-woven cotton fiber, and finally FeCl is impregnated 3 ·6H 2 O solution; wherein, the active amino group on dopamine and the carboxyl group of sodium alginate are subjected to amidation reaction, the phenolic hydroxyl group of the obtained polymer is used for modifying the surface of the fiber, and FeCl is impregnated 3 ·6H 2 O solution of carboxyl of alginic acid and phenolic hydroxyl of dopamine with Fe 3+ Chelating to form a complex, Fe 3+ Combined with the above materials, can exert and enhance hemostatic effects, and simultaneously, Fe 3+ Can also oxidize catechol groups on dopamine to generate good antibacterial property. |
