Weaving method of polylactic acid filament fabric

The invention belongs to the technical field of polylactic acid fabrics, and discloses a weaving method of a polylactic acid filament fabric, which comprises the following steps: unwinding a polylactic acid filament cone yarn, and doubling and twisting a filament single yarn after netting and tension application by a netting nozzle; the conical angle of the polylactic acid filament cone yarn ranges from 30 degrees to 35 degrees. The tension is 50 to 60 CN; doubling and twisting polylactic acid filament yarn serves as warp yarn, the warp yarn is subjected to sectional warping to form a warp beam, the warp beam and weft yarn are woven on a weaving machine, and the polylactic acid filament fabric is obtained. According to the method, the number of times of yarn breaking during doubling and twisting of polylactic acid is small, the quality of doubled single yarn can be improved, and weaving procedures are facilitated. In addition, by improving the warping displacement and the like, the distance between the yarns
