Composite fiber-based protective material as well as preparation method and application thereof

The invention discloses a composite fiber-based protective material as well as a preparation method and application thereof, and belongs to the technical field of functional textile materials. The composite fiber-based protective material comprises a one-way moisture-conducting fiber membrane, a bacteriostatic sweat-absorbing layer and a waterproof moisture-permeable membrane which are sequentially stacked, and the one-way moisture-conducting fiber membrane comprises a hydrophobic fiber membrane and a hydrophilic fiber membrane clamped between the hydrophobic fiber membrane and the bacteriostatic sweat-absorbing layer; the average pore size of the hydrophobic fiber membrane is larger than the average pore size of the hydrophilic fiber membrane. The average pore size of the hydrophobic fiber membrane is 10-18 [mu] m; the average pore diameter of the hydrophilic fiber membrane is 1.0 [mu] m to 2.3 [mu] m. The composite fiber-based protective material is prepared from the one-way moisture-conducting fiber film,
