The invention provides an antibacterial polylactic acid fabric and a preparation method thereof. The antibacterial polylactic acid fabric is prepared from a polylactic acid fabric, N-vinyl pyrrolidone(NVP) and a silver-containing compound, specifically, polyvinyl pyrrolidone (PVP) is grafted on the polylactic acid fabric through radiation grafting, and meanwhile, silver nanoparticles are loaded on the surface of the polylactic acid fabric through radiation reduction, so that the antibacterial polylactic acid fabric is obtained. The antibacterial polylactic acid fabric has antibacterial and hydrophilic functions at the same time, can be applied to the field of textile fabrics, and has good skin friendliness and hygroscopicity. 本发明提供了一种抗菌聚乳酸织物及其制备方法，所述抗菌聚乳酸织物由聚乳酸织物、N-乙烯基吡咯烷酮(NVP)和含银化合物制备得到，具体地，经过辐射接枝在聚乳酸织物上接枝聚乙烯基吡咯烷酮(PVP)，同时通过辐射还原在聚乳酸织物表面负载银纳米颗粒，从而得到抗菌聚乳酸织物。本发明的抗菌聚乳酸织物同时具有抗菌性和亲水性的功能，可应用于纺织面料领域，具有较好的亲肤性和吸湿性。
