Antibacterial polyester fabric and preparation method thereof

The invention relates to an antibacterial polyester fabric and a preparation method thereof, and is characterized in that the antibacterial polyester fabric is prepared by the following method: firstly, reacting silver oxide with prochloraz to prepare a silver complex; secondly, dissolving a silver complex and a sodium lignin sulfonate dispersing agent in tap water to prepare finishing liquid; and finally, performing antibacterial finishing on the polyester fabric in the finishing liquid to obtain the antibacterial polyester fabric. The initial bacteriostasis rate of the prepared antibacterial polyester fabric to escherichia coli reaches 98.0% or above, after 10 times of washing, the antibacterial polyester fabric still has high antibacterial performance to escherichia coli, and the bacteriostasis rate reaches 95.0% or above; the initial bacteriostasis rate of the antibacterial polyester fabric to staphylococcus aureus reaches 99.0% or above, after the antibacterial polyester fabric is washed for 10 times, th
