The invention relates to an antibacterial finishing method of cotton fabrics. The finishing method comprises the following steps: preparing a nano zinc oxide complex solution, preparing a quaternary ammonium salt polymer solution; mixing the nano zinc oxide complex solution and the quaternary ammonium salt polymer solution to obtain a zinc oxide-quaternary ammonium salt polymer composite antibacterial agent; mixing the zinc oxide-quaternary ammonium salt polymer composite antibacterial agent with water to obtain an antibacterial finishing solution with a concentration of 50 to 500 g/L; using the antibacterial finishing solution to carry out a dip padding treatment on cotton fabrics, and finally drying the cotton fabrics after the dip padding treatment. The adopted antibacterial finishing agent is a complex of quaternary ammonium salt polymer and nano zinc oxide. The cotton fabrics processed by the provided antibacterial finishing method have a good antibacterial performance. The using amounts of two antibacte
