The invention discloses an antibacterial cotton cloth and a preparation method thereof. The antibacterial cotton cloth is produced by the following method and the method comprises the following steps: adding the silver-carrying hydroxylapatite, sodium hexametaphosphate, deacetylated chitin and citric acid into the water to form a solution; placing an absorbent cotton cloth into the solution prepared by the step (1) for padding and the residual padding rate is 60-100%, then pre-baking for 1-3 minutes at the temperature of 80-100 DEG C and then baking for 1-4 minutes at the temperature of 130-170 DEG C, therefore, the antibacterial cotton cloth can be produced. The invention adopts the silver-carrying hydroxylapatite which has broad antibacterial spectrum and good compatibility with the human body as the antibacterial finishing agent, therefore, the cloth is highly safe; the molecule of the silver-carrying hydroxylapatite contains a hydroxy base group that can produce acting force with the cellulose molecule, thus being capable of improving the binding strength between the antibacterial finishing agent and the cotton gauze; and the cloth has good washing fastness; The antibacterial cotton cloth of the invention contains antibacterial finishing agent that can kill or restrain the growth of the bacteria, and simultaneously keeps the good permeability, moisture absorption property and softness of the cotton cloth.

The invention relates to the field of textiles, in particular to a solvent method based high-wet-modulus bamboo, wood and cotton mixed fiber and a preparation method thereof. The preparation method includes steps: activating, adding bamboo, wood and cotton mixed pulp into deionized water, adjusting a pH value, adding cellulase for activating, and adding alkali for adjusting the pH value; pressing;pre-dissolving, and adding water solution containing N-methylmorpholine-N-oxide in mass percent of 50-88%; dissolving, heating, vacuumizing, dewatering, dissolving, homogenizing and de-aerating; filtering; spinning, and adopting a dry-wet method for spinning forming; washing; bleaching; oiling; drying. The preparation method is simple in operation, free of industrial pollution, low in energy consumption, high in safety and suitable for large-scale industrial continuous production of solvent method based bamboo, wood and cotton mixed fibers. The bamboo, wood and cotton mixed fiber prepared according to the method keeps natural physical and chemical performances of bamboo, wood and cotton fibers and is free of chemical residues and high in wet modulus.
