Zusammenfassung:	The invention provides a preparation method of a polylactic acid spinning fiber based on a photocatalytic antibacterial nano-material. The preparation method comprises the following steps: preparing the photocatalytic antibacterial nano-material, preparing a modified polylactic acid emulsion and preparing the polylactic acid spinning fiber based on the photocatalytic antibacterial nano-material. According to the polylactic acid spinning fiber based on the photocatalytic antibacterial nano-material, the porous activated carbon and the photocatalytic antibacterial nano-material are co-spun into the fiber, and by means of the characteristic of large specific surface area of the spinning fiber, the spinning fiber adsorbs bacteria and sterilizes at the same time, and has a better antibacterial function. The polylactic acid is covalently crosslinked with the photocatalytic antibacterial nano material and the porous activated carbon, so that the spinning fiber has better structural stability and solubility resistanc
