The invention discloses an asymmetric layered porous antibacterial hemostatic sponge dressing as well as a preparation method and application thereof. The method comprises the following steps: pre-crosslinking chitosan and halloysite nanotubes, further crosslinking with keratin, carrying out directional freeze drying on the crosslinked mixed solution to obtain a sponge material, and coating one surface of sponge with a PDMS solution to obtain the asymmetric layered porous antibacterial hemostatic sponge dressing. The layered hemostatic sponge dressing with rapid and effective hemostatic performance, antibacterial activity and biocompatibility is prepared by combining a freeze drying technology and asymmetric design and utilizing feather keratin, halloysite nanotubes (HNTs) and chitosan (CS), and the layered hemostatic sponge dressing has a wide application prospect in the field of wound healing.

The invention discloses a preparation method of a non-woven fabric. The non-woven fabric is formed by reinforcing a double-layer fiber net; the upper-layer fiber net is formed by uniformly mixing and carding first fine denier fibers and second fine denier fibers which are different in thickness; the first fine denier fibers are ES (Ethylene-Propylene Styrene) fibers with the density of 0.6 to 1.0 D The surface of the first fine denier fiber is subjected to first-time hydrophobic zinc oxide evaporation / magnetron sputtering treatment, so that a first layer of zinc oxide is formed on the surface of the first fine denier fiber, and the particle size of the zinc oxide is 10-100 nm; second-time hydrophobic zinc oxide evaporation / magnetron sputtering treatment is conducted on the surface of the first fine denier fiber, so that a second layer of zinc oxide is formed on the surface of the first layer of zinc oxide, and the particle size of zinc oxide is 2-30 nm; constructing a zinc oxide structure of which the surface is slightly convex on the surface of the first fine denier fiber; the super-hydrophobicity of the fiber surface is realized. According to the ES fiber disclosed by the invention, a surface micro-bulge structure is constructed through double-layer ZnO, so that the super-hydrophobic and antibacterial effects of the fiber surface are realized.
