The invention provides a processing method of a flame-retarding and antibacterial jacquard fabric, aiming at solving the technical problems that no corresponding manufacturing method for an existing jacquard fabric exists, the manufacturing is complicated and the like. The processing method of the flame-retarding and antibacterial jacquard fabric comprises the following steps: a, taking materials:weighing the following raw materials by mass percent: 15 to 25 percent of chitin, 10 to 18 percent of citric acid, 5.5 to 8.5 percent of a mite inhibition agent, 3.5 to 6.5 percent of a flame retardant, 2 to 4 parts of a de-foaming agent, 1 to 3 percent of a softening agent and 50 to 60 percent of water; b, preparing: adding the chitin, the citric acid, the mite inhibition agent, the flame retardant, the de-foaming agent, the softening agent and the water into material preparation equipment and stirring to obtain a finishing liquid; c, carrying out padding: carrying out padding on the jacquard fabric by adopting the finishing liquid obtained by step b; and d, drying: putting the finished jacquard fabric into a drying oven and drying to obtain the finished-product flame-retarding and antibacterial jacquard fabric. The processing method has the advantage of rapid processing speed.
