The invention discloses mildew-resistant mothproof aramid short fiber composite raw paper. Antibacterial agents prepared into a mixed antibacterial slurry, the mixed antibacterial slurry is added in raw materials, and a lasting antibacterial property, environmental protection and no pollution to the environment are achieved when the composite raw paper is compared with paper prepared through traditional methods of spraying, gluing, coating, dipping and the like. Aramid short fibers and calotropis gigantea fibers are modified, spinning is carried out again, novel composite fibers are prepared, the novel composite fibers are added in the raw materials, mutual combination is achieved, and the toughness and the intensity of paper are raised obviously. isooctyl triethoxysilane and other effective auxiliary agents are added, Si-C bonds and hydroxyls in cellulose can form chemical bonds, and therefore special surface properties are given to the fiber. the prepared composite raw material has sterilization, peculiar smell removing and harmful chemical substance decomposition functions, has a lasting and effective wide spectrum antibacterial effect on escherichia coli and staphylococcus aureus, and has advantages of environmental protection, self-cleaning, mildew resistance, moth resistance, no pollution to the environment, simple and practical preparation method and low cost.
